Autores: Romero Romano, Carlos Osvaldo.
Actualmente el uso excesivo de fertilizantes sintéticos en la producción agrícola y el mal uso de estiércoles generados en las actividades pecuarias, ha generado una serie de problemas ambientales en todo el mundo, ejemplo de esto es la contaminación de las aguas superficiales y subterráneas por efecto de elementos como nitrógeno, en forma de nitrato, y fósforo, como fosfato, a la vez que cationes como potasio (K+), magnesio (Mg++), etc. Por otro lado, el uso excesivo de fertilizantes genera el empobrecimiento de los suelos agrícolas; debido a la pérdida de materia orgánica y la biota del suelo. Con base a esta problemática, en este trabajo se presentan tres investigaciones; que pueden resultar como alternativas para la reducción del uso de fertilizantes...

The United Nations (UN) Rio+20 summit committed nations to develop a set of universal sustainable development goals (SDGs) to build on the millennium development goals (MDGs) set to expire in 2015. Research now indicates that humanity&amp;#8217;s impact on Earth&amp;#8217;s life support system is so great that further global environmental change risks undermining long-term prosperity and poverty eradication goals. Socioeconomic development and global sustainability are often posed as being in conflict because of trade-offs between a growing world population, as well as higher standards of living, and managing the effects of production and consumption on the global environment. We have established a framework for an evidence-based architecture for new goals...

Six of New Zealand&amp;#8217;s 16 regional councils are trialling collaborative planning as a means of addressing complex challenges in freshwater management. Although some work has been undertaken to evaluate similarities and differences across those processes, the success or failure rests with the public&amp;#8217;s acceptance of the processes and their outcomes. This is the first study to evaluate public perceptions of freshwater management in regions with collaborative processes.  We surveyed 450 respondents in Hawke&amp;#8217;s Bay, Northland, and Waikato, some of whom live in catchments in which collaborative processes are under way and some of whom do not. In addition to assessing awareness of the collaborative planning processes, the survey...

A Participatory Modeling Process to Capture Indigenous Ways of Adaptability to Uncertainty: Outputs From an Experiment in West African Drylands
Provedor de dados: Ecology and Society
Autores: d'Aquino, Patrick; CIRAD; daquino@cirad.fr; Bah, Alassane; UMISCO ESP UCAD Dakar; alassane.bah@gmail.com.
Over the centuries, local communities have shaped atypical rules to deal with the uncertainty of their environment. They have developed complex prototypes for flexible overlapping institutions and arrangements to adapt their rules and uses to their uncertain environment. Today, this indigenous way of flexibly institutionalizing access rules could provide blueprints for dealing with uncertainty issues resulting from global change as well as designing practical guidelines for implementing resilient management. However, transforming indigenous skills for developing institutional flexibility into operational management rules that are appropriate in the current environmental and socioeconomic context is a huge challenge. However, communities could easily...

The evolution and performance of river basin management in the Murray-Darling Basin
Provedor de dados: Ecology and Society
Autores: Ross, Andrew; Australian National University; a.ross@anu.edu.au; Connell, Daniel; Australian National University; daniel.connell@anu.edu.au.
We explore bioregional management in the Murray-Darling Basin (MDB) in Australia through the institutional design characteristics of the MDB River Basin Organization (RBO), the actors and organizations who supported and resisted the establishment of the RBO, and the effectiveness of the RBO. During the last 25 years, there has been a major structural reform in the MDB RBO, which has changed from an interstate coordinating body to an Australian government agency. Responsibility for basin management has been centralized under the leadership of the Australian government, and a comprehensive integrated Basin plan has been adopted. The driving forces for this centralization include national policy to restore river basins to sustainable levels of extraction,...

China and Vietnam have developed some of the most ambitious payments for ecosystem services (PES) initiatives for watershed conservation and forest management. These include the Sloping Land Conversion Programme in China and pilot projects designed to implement Decision 380 and the subsequent national PES law in Vietnam. This study reviews how these two government-driven initiatives are achieving their environment and development objectives in terms of their institutional arrangements, implementation in practice, and sustainability prospects. Although it remains too soon to determine the effects of these programs on watershed services, early evidence indicates that they are resulting in vulnerable land being retired from cultivation supported, in some...

Autores: Casagrandi, Renato; Dipartimento di Elettronica e Informazione, Politecnico di Milano; casagran@elet.polimi.it; Rinaldi, Sergio; CIRITA, Politecnico di Milano; rinaldi@elet.polimi.it.
This paper shows that it is difficult, if not impossible, to formulate policies that guarantee that tourism can be maintained for a long time without severely impacting on the environment. The analysis is purely theoretical and is based on very simple and general assumptions about the interactions between the three main components of the system: the tourists, the environment, and the capital. These assumptions are encapsulated in a so-called minimal model, used to predict the economic and environmental impact of any given policy. This paper is of value for three reasons. First, it introduces the approach of minimal descriptive models in the context of tourism, which has traditionally been dominated by the use of black-box econometric models. Second, the...

Provedor de dados: Ecología Austral
Autores: Machado,Renata F; Cerezer,Felipe O; Hendges,Carla D; Cáceres,Nilton C.
We evaluated several factors that might be related to the home-range size of felids at both inter and intraspecific levels. At the interspecific level, we tested the influence of body mass on home range size of 19 felid species, while controlling for phylogeny. At the species level, we evaluated the effect of sex and habitat type (open vs. closed) on the home range size of three species of felids occurring in America, Panthera onca, Leopardus pardalis and Puma concolor, which are among the most studied species concerning home ranges. Body mass, sex, and home range data were extracted from the Pantheria database (for 19 species, for interspecific comparisons) and from 48 studies for intraspecifc comparisons. We assessed the influence of body mass on the...

Provedor de dados: Engenharia Agrícola
Autores: Coradi,Paulo C.; Martins,Márcio A.; da Costa,Douglas R.; Vigoderis,Ricardo B.; Tinôco,Ilda de F. F.
ABSTRACT Animal welfare is essential for livestock yield gains, which has been ethically justifiable and socially acceptable. Thus, our research aimed to test computational fluid dynamics model (CFD) to simulate heated air within a poultry barn. Data were simulated in CFD software based on Navier-Stokes equations (geometry of 3 m x 6 m, considering a symmetric mesh). As boundary conditions, a temperature of 38ºC was considered for walls where heating pipe outlets are, to the west side, besides a heat flow of zero, in symmetry to the same side. As for the sides east, south and north, walls were taken as isolated, i.e. heat flow equals to zero. The aviary heating system did not achieve a homogeneous temperature distribution, heat flow, heated air pressure...

Provedor de dados: Engenharia Agrícola
Autores: Pereira,Danilo F.; Tavares,Bartira de O.; Lean,Priscilla A. B. Mac.
ABSTRACT: Lighting, either in its intensity or in its luminous spectrum, affects the eggs quality. This study evaluated the effect of four lamps (sodium vapor lamp, mercury vapor lamp, fluorescent lamp and incandescent lamp) that have different luminous spectra in the form of commercial poultry eggs. For this, 60 laying hens of the same age were separated for 63 days in four aviaries with reduced and distorted scale. In each treatment, different lamps were installed which provided similar luminous intensities. At the end of the period, these eggs were taken as samples for the fluorescent, incandescent, mercury vapor and sodium vapor lamps. In this way, images were made of these eggs, using a camera installed on a fixed tripod on a flat table with black...

Sistema silvipastoris - SSPs - combinam espécies lenhosas (árvores, arbustos, palmeiras entre outros) ao sistema de produção animal, em alguma forma de arranjo temporal ou espacial. Os SSPs são ferramentas importantes do desenvolvimento sustentável, já que combinam produção com a conservação dos recursos naturais. Alem de buscar atender a várias necessidades dos produtores rurais (alimento, madeira, lenha, forragem, plantas medicinais e fibras), podem auxiliar na conservação dos solos, recupração de microbacias, recomposição ordenada de áreas florestais, e manutenção da biodiversidade, entre outros. A implantação e o manejo da SSPs são mais complexos que em sistemas pecuários convencionais, mas ainda assim, pode representar um significativo aporte de...

A agricultura e o sistema alimentar do novo capitalismo.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: LOPES, M. A.
O capitalismo e a agricultura moderna que dele emergiu ajudaram a tirar milhões de pessoas da pobreza, produzindo inovações que melhoraram de forma marcante os padrões de vida e o bem-estar humano no último século. A Revolução Verde, na segunda metade do século 20, bem ilustra o impacto do capitalismo industrial no campo. Houve um vasto aumento na produção agrícola devido à incorporação de cultivos de alto rendimento, mecanização das lavouras, amplo uso de fertilizantes químicos e proteção de plantas com defensivos. Ainda assim, cresce a percepção de que o atual paradigma de capitalismo já não atende as necessidades do presente e muito menos nos habilita ao enfrentamento de riscos que poderão emergir do futuro. O texto apresenta estas e outras reflexões...

Na criação tecnificada de suínos, muita preocupação tem sido atribuída ao destino final dos resíduos gerados por este sistema, principalmente na geração de fertilizantes orgânicos e sua aplicação no ambiente. No ano de 2010, foram abatidos, aproximadamente, 36,8 milhões de cabeças e espera-se que até o ano de 2020 este número aumente, com incremento na produção de 24% (MAPA, 2010). Assim, a demanda para o aproveitamento dos resíduos gerados na criação de suínos será cada vez maior, fazendo com que a pesquisa necessite desenvolver recursos tecnológicos que equalizem a relação produção/qualidade ambiental.

Você sabe que as abelhas são insetos? Os insetos são os seres mais adaptados do planeta e considerados a forma de vida dominante na Terra! Isso porque existem mais de setecentas mil espécies de insetos. São tantos e com formas de corpo tão diferentes que às vezes é difícil reconhecê-los. Mas todos eles têm algumas características em comum. Você quer saber o que abelha, borboleta, gafanhoto, pulga, formiga e mosca têm em comum? Todos têm um par de antena, três pares de pernas e um esqueleto externo, chamado de exoesqueleto. Existem outras semelhanças e várias diferenças. Alguns insetos, como o mosquito da dengue, causam doenças e são nocivos. Mas a maioria tem um importante papel na vida humana e de outros animais. Entre os insetos importantes, as abelhas...

Os pesticidas compreendem um largo espectro de produtos quimicos usados na agropecuaria para controlar pragas, doencas de plantas e animais e combater ervas invasoras de culturas e pastagens. A eficacia comprovada desses produtos, aliada a crescente demanda setorial, viabilizou rapidamente a producao industrial, com o objetivo de incrementar a produtividade dos sistemas agropecuarios direcionados para a producao de alimentos. Os efeitos imediatos de toxicidade humana e ambiental foram durante muitos anos negligenciados ou considerados de menor relevancia.

The influence of the environment on the variability of monthly tuna biomass around a moored, fish-aggregating device
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Doray, Mathieu; Petitgas, Pierre; Nelson, Laetitia; Mahevas, Stephanie; Josse, E; Reynal, Lionel.
Fish-aggregating devices (FADs) are increasingly used worldwide to enhance tuna catches. Meanwhile, ecosystem-based management of this fishery is constrained by a paucity of information regarding the interaction of FAD-associated tuna aggregations with their local environment. This paper reports the results of a nine-month study around a FAD moored near Martinique Island, aimed at assessing the effects of the local environment on the variability of monthly estimates of proximate tuna biomass. Dual-frequency, active acoustics provided highresolution quantitative data on the pelagic community around the FAD, from fish to micronekton forage. Geostatistics were used to compute biomass estimates of the tuna aggregation comprising most of the FADassociated fish...

Compactation for a better management of marine biomass: applications to fish discards and by-products
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Perez-galvez, Raul.
In the framework of the future application of a zero-discard policy in EU fisheries, this thesis aims to develop and implement an efficient and integral waste management both on board the fishing vessels and in land (fish auctions and fish processing industry). To this end, it proposes a compaction operation able to reduce the volume and the water activity of the fish wastes, thus favouring their handling and reducing the economical costs associated to their transport and storage. To asses the viability of a waste compaction operation, the main operation factors governing the process were identified, and their influence upon the performance of the compacting operation was investigated by a statistical approach. Sardine was chosen as fish species since it...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Soletchnik, Patrick; Ropert, Michel; Mazurie, Joseph; Fleury, Pierre-gildas; Le Coz, Florence.
Oyster mortality was monitored at multiple sites along the French coastline (around 5 500 km) between 1993 and 2005. Mortality data for one- and two-year-old oysters were collected over 10–12 years in 39 oyster culture sites bordering 3 different "seas": the English Channel, Bay of Biscaye and Mediterranean. Combining these data with records from environmental monitoring databases, 11 of these sites had consistent chronological data sets including both environmental data and mortality records. Mortality in one-year-old oysters was clearly summer mortality (49% of their annual mortality) whereas mortality of two-year-olds occurred mostly in spring (51%). Analysis of variance revealed that "coastal area" was the main influence on mortality of one-year-olds...

In the context of the Water Framework Directive, the French Water Agencies were asked to justify exemptions, for disproportionate cost reasons, to the “good water” status in a series of river basins in 2015. The ministry of the Environment and the economists of the Water Agencies agreed on the fact that this justification would be based on cost-benefit analyses. A great number of cost-benefit analyses were carried out on water bodies or groups of water bodies. This article reports on this experience conducted by the French Water Agencies. It highlights the fact that the large majority of restoration projects generated higher costs than benefits. It suggests that the implementation of the Water Framework Directive could be considerably limited by the use of...

In the marine environment, positive law generates multiple zones and regulatory limits that overlap in space, justifying a cartographic representation as a relevant approach to promote understanding (synthetic vision), analysis (highlighting legal anomalies, inconsistencies and redundancies), dissemination and communication to different audiences (awareness-raising). The article presents a methodology leading to the mapping of marine and coastal environmental law in West Africa, using a geographic information base to produce static or interactive cartographic representations via a Geographic Data Infrastructure (GDI). It shows the contribution of this type of mapping to a transversal approach in a multi-activity, multi-sectoral and multi-scale context. A...

Autores: Person, Roland; Aoustin, Yannick; Blandin, Jerome; Marvaldi, Jean; Rolin, Jean-francois.
For a long time, deep-sea investigation relied on autonomous bottom landers. Landers call vary in size from 200 kg weight to more than 2 t for the heaviest scientific landers and are used during exploration cruises oil medium periods, from one week to some months. Today, new requirements appear. Scientists want to understand in detail the phenomena outlined during exploration cruises, to elaborate a model for future forecasting. For this, it is necessary to deploy instrumentation at a precise location often for a long period. A new mode of ocean science investigation Using long-term seafloor observatories to obtain four dimensional data sets has appeared. Although this concept has been proposed for many years, the high level of investment required limits...

Autores: Pergent, G; Mendez, S; Pergent-martini, C; Pasqualini, V.
While the extension of aquaculture along the coasts of the Mediterranean islands is today an economic priority, no data is available on the impact of these facilities on the littoral environment in general, and in particular on the Posidonia oceanica meadows that are responsible for the richness and diversity of these biotopes. The impact of fish farming facilities in the marine littoral environment is assessed at three Mediterranean sites in Corsica and Sardinia. Various parameters are considered: (i) the amount of light available, (ii) the nature of the sediment, and (iii) the vitality of the Posidonia oceanica beds. The findings confirm the impact of the aquaculture facilities within the water column (increase in turbidity, enrichment of the sediment in...

Autores: Fromentin, Jean-marc; Fonteneau, Alain; Restrepo, Victor.
During the last SCRS plenary meeting, the sub-committee on environment suggested to present a document on the ‘Ecosystem Approach to Fisheries’ (EAF). This document firstly recalls the general scientific and institutional background of EAF, then we propose a synoptic view of EAF, including four main domains: governance, exploitation, resources and impacts on ecosystems. The way that EAF is tackled within the various tuna commissions is then summarised. Finally, we rapidly examine the way the SCRS could cope with EAF issues and we suggest to merge the sub-committee on environment with this on by-catch into a single subcommittee on ecosystem.

Protection of marine benthic habitats in the Pacific islands. A case study of Guam
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gawel, Mj.
Guam consists of a single main island surrounded by shallow fringing coral reefs. The marine species and ecology of Guam's coral reefs have been studied extensively, especially through programs of the University of Guam's Marine Laboratory. In addition to overfishing and destructive fishing practices, the marine benthic communities of Guam have been damaged by major storm waves; loss of corals to crown of thorns starfish predation; damage by recreational swimmers, divers and watercraft operators; grounding of ships and pollutant discharges of sewage and of stormwater. But the most serious damage is due to accelerated siltation, sedimentation and turbidity due to erosion related to land use practices. Steps are being taken to protect Guam's coral reefs and...

Autores: Henry, L. -a.; Stehmann, M. F. W.; De Clippele, L.; Findlay, H. S.; Golding, N.; Roberts, J. M.
Highly localized concentrations of elasmobranch egg capsules of the deep-water skate Bathyraja richardsoni were discovered during the first remotely operated vehicle (ROV) survey of the Hebrides Terrace Seamount in the Rockall Trough, north-east Atlantic Ocean. Conductivity–temperature–depth profiling indicated that the eggs were bathed in a specific environmental niche of well-oxygenated waters between 4·20 and 4·55° C, and salinity 34·95–35·06, on a coarse to fine-grained sandy seabed on the seamount's eastern flank, whereas a second type of egg capsule (possibly belonging to the skate Dipturus sp.) was recorded exclusively amongst the reef-building stony coral Solenosmilia variabilis. The depths of both egg-laying habitats (1489–1580 m) provide a de...

Autores: Pernet, Fabrice; Barret, Jean; Marty, Claire; Moal, Jeanne; Le Gall, Patrik; Boudry, Pierre.
Mortality of oysters Crassostrea gigas occurred along the coasts of France during summer 2008, causing a serious crisis in French oyster production. During spring to summer 2008, 5 groups of 1-yr old oysters of different origins and ploidy levels deployed in the Thau lagoon (France) were sampled for biometrical and biochemical analyses; environmental parameters were monitored in the same area. Mortality occurred in 2 episodes: 13 May to 10 June and 24 June to 9 July. Wild-collected oysters showed mortality sooner than other groups but total overall mortality was 85% in all groups. Mortality occurred when seawater temperature was &gt;19 degrees C during the reproductive season when energetic reserves of oysters were at their lowest. Energy reserve levels...

Autores: Gilbert, Franck; Galgani, Francois.
A new method for the assessment of several contaminant effects on marine microalgae (Tetraselmis suesica, Skeletonema costatum) has been developped. The method is based on the measure of cells esterase activity using a fluorimetric stain, fluorescein diacetate (FDA). The experiments are performed in microplates using a fluorimetric microplate reader. The different steps of the experiments and the data processing are controlled by an original specific software. Application of the system for rapid ecotoxicological tests (determination of LC 50) and for assessment of environment quality by observation of water samples are proposed.

Mass mortality outbreaks (90-100%) in both juvenile and adult blue mussels were reported in 2014 along the Pertuis Charentais area of the French Atlantic coast. A series of studies were carried out to learn more about the phenomenon through detecting pathogens, describing environmental conditions and establishing the physiological status of the animals. Bacteria identif ied as belonging to the V. splendidus species were detected in dying mussels and seem able to cause mortality in blue mussels in the laboratory. Unusual environmental conditions (large amounts of fresh water, re-suspension of sediments during a series of storms, and a high renewal rate of specific water masses in Brittany’s Pertuis area) may be partially responsible for sparking the phenomen

The multifactorial etiology of massive Crassostrea gigas summer mortalities results from complex interactions between oysters, opportunistic pathogens and environmental factors. In a field survey conducted in 2014 in the Mediterranean Thau Lagoon (France), we evidenced that the development of the toxic dinoflagellate Alexandrium catenella, which produces paralytic shellfish toxins (PSTs), was concomitant with the accumulation of PSTs in oyster flesh and the occurrence of C. gigas mortalities. In order to investigate the possible role of toxic algae in this complex disease, we experimentally infected C. gigas oyster juveniles with Vibrio tasmaniensis strain LGP32, a strain associated with oyster summer mortalities, after oysters were exposed to Alexandrium...

Water samples were collected around the communities of a hydrothermal mussel, Bathymodiolus sp., in the Lucky Strike (1700 m depth) and Menez Gwen (850 m depth) areas, Mid Atlantic Ridge, and analysed for chemical constituents. The environment surrounding the organisms consists in sea water (88 to 100%) mixed with hydrothermal fluid with pH between 6.2 and 8, Sigma S (H2S + HS-) concentrations from 0 to 62 mu mol l(-1). High dissolved organic carbon (DOC) concentrations suggest a highly productive ecosystem. Production of ammonium and DOG, consumption of nitrate and sulfide in the vicinity of the organisms are among the environmental changes found in relation with local biological activity. Concentrations of Cu and Pb were high, implying that the organisms...

Trophic conditions and water temperature strongly influence bivalve physiological processes and metabolism. In black-lip pearl oyster Pinctada margaritifera, these parameters have been shown to affect shell biomineralization. The present study investigated the effect of preoperative food level (i.e., microalgal concentration) and temperature on pearl biomineralization. Donor and recipient oysters were conditioned at different levels of food and temperature during the preoperative phase to evaluate the influence of these factors on 1) pearl retention rate (grafting success), 2) expression of genes involved in biomineralization in the mantle and pearl sac and 3) pearl quality traits. Our study confirmed the influence of both microalgal concentration and...

The pearl oyster (Pinctada margaritifera) aquaculture in French Polynesia and the indirect impact of long-distance transfers and collection-culture site combinations on pearl quality traits
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ky, Chin-long; Broustal, Floriane; Potin, Dan; Lo, Cedrik.
In French Polynesia, the P. margaritifera pearl aquaculture industry is spread over a vast area, as large as Europe. All the oysters for this the highly economically important activity are supplied from just a few collection lagoons, but they are grown in numerous sites across three archipelagos (Gambier, Society and Tuamotu). Many oyster transfers thus indirectly bring about grafting combinations mixing different geographic origins and production sites. This study aims to examine the impact of such graft combinations on cultured pearl quality traits. For this, six homogeneous and standardised experimental graft combinations (N = 6197) were conducted at commercial scale in the two growing locations the most frequently used in French Polynesia: Arutua atoll...

Relating environmental factors to species occurrence is a fundamental step in a better understanding of the community structure, the spatial and temporal dynamics of populations and how species may respond to environmental changes. In this paper, we used phytoplankton occurrence data, from a French national phytoplankton monitoring network, and environmental variables with the aim of characterizing the realized ecological niches of phytoplankton groups. We selected 35 phytoplankton taxa representing the most important taxa in terms of occurrence frequency and abundance along the French coast of the eastern English Channel, the Southern Bight of the North Sea and the Atlantic Ocean. We show that environmental variables such as nutrient concentration, water...

This article presents the results of multidisciplinary research (geochemistry, sociology) into the increasing concentrations of silver (Ag and nanoAg) in the environment and their potential impact on aquatic environments. We investigate simultaneously the risk of contamination of these environments by silver and the process of the social and political construction of this risk by water managers, health authorities, agencies and committees responsible for expert evaluations, environmental associations, and potential users of silver or nano-silver. Four updated models of risk construction allow us to understand the logic of arguments mobilized at this stage of the emerging risk. This interdisciplinary cooperation opens up possibilities for dealing with some...

Aims: This work investigates the maintenance of viability and potential virulence of Vibrio parahaemolyticus in a viable but nonculturable population (VBNC) state by reverse transcription-polymerase chain reaction (RT-PCR).   Methods and Results: Housekeeping genes, 16S-23S rDNA and rpoS, as well as virulence genes, tdh1 and tdh2, were selected and detected by PCR in a pathogenic strain of V. parahaemolyticus (Vp4). Their expression was then studied by RT-PCR in V. parahaemolyticus Vp4 cultivated in rich medium at 37degreesC. The 16S-23S rDNA and rpoS, tdh1, tdh2 genes were transcripted at the mid-logarithmic, stationary and late stationary phases, corresponding to various physiological states. The expression of these genes was also studied by RT-PCR in a...

Interactions entre traits de personnalité des téléostéens, environnement et polluants
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Alfonso, Sebastien.
In the frame of this thesis, we first studied the establishment of personality in teleost, the consistency across context and different life stages as well as the associated physiological mechanisms. Personality appeared consistent across contexts over a short time period but it was no longer the case over a long period of time, especially between different life stages. Physiological mechanisms of stress regulation, as well as activity and neural plasticity, differed according to individual boldness. Then, we studied the physiological and behavioural responses of teleost fish chronically exposed to an environmentally relevant mixture of POP (PCBs and PBDEs), as well as those of their unexposed offspring. Different behavioural alterations in larval...

This study aims to improve understanding of causes of mortalities in oyster Crassostrea gigas in pertuis charentais related to environmental parameters and the kinetics of targeted infectious agents, such as bacteria Vibrio splendidus (group ) and V. aestuarianus and Ostreid herpesvirus OsHV-1. Two sampling campaigns were carried out on the site of Agnas in 2009 and 2010, before, during or following mortality events of spat from March to September. The approach is to detect and quantify in short time step infectious agents from tissues of farmed oysters placed on rack and in various samples taken nearby: native oysters and other species (wild mussels and barnacles), seawater and sediment. With physical and chemical automatic probes placed on the site,...

The Celtic Sea Through Time and Space: Ecosystem Modeling to Unravel Fishing and Climate Change Impacts on Food-Web Structure and Dynamics
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hernvann, Pierre-yves; Gascuel, Didier; Grüss, Arnaud; Druon, Jean-noël; Kopp, Dorothee; Perez, Ilan; Piroddi, Chiara; Robert, Marianne.
Both trophic structure and biomass flow within marine food webs are influenced by the abiotic environment and anthropogenic stressors such as fishing. The abiotic environment has a large effect on species spatial distribution patterns and productivity and, consequently, spatial co-occurrence between predators and prey, while fishing alters species abundances and food-web structure. In order to disentangle the impacts of the abiotic environment and fishing in the Celtic Sea ecosystem, we developed a spatio-temporal trophic model, specifically an Ecopath with Ecosim with Ecospace model, for the period 1985–2016. In this model, particular attention was paid to the parameterization of the responses of all trophic levels to abiotic environmental changes....

Déterminisme de la croissance de l'huître creuse, Crassostrea gigas, en Bretagne : Méthodologie d'élaboration d'un modèle global.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dormoy, Jean-marc.
Based on a four years survey of Pacific Oyster Crassostrea gigas growth in the main shellfish farming areas of Brittany from 1989 to 1992, this report is a first attempt to explain the differences between sites and years. The determinist growth models do not suit to this objective, for methodological and practical reasons. Nevertheless, they provide the conceptual basis of a global model by identifying the reliable environmental parameters for a statistical explanation of growth results. The present study proposes a methodology for a global statistical model using the main stages of the ecological and biological processes of shellfish growth. These propositions are based on the analysis of the determinist model's constraints, and also on the identification...

Is pearl colour produced from Pinctada margaritifera predictable through shell phenotypes and rearing environments selections?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ky, Chin-long; Le Pabic, Lore; Koua, Manaarii Sham; Molinari, Nicolas; Nakasai, Seiji; Devaux, Dominique.
The black-lipped pearl oyster, Pinctada margaritifera is the most important farmed mollusc species in French Polynesia. Donor oyster selection among wild P. margaritifera individuals, chosen according to their inner shell colour, makes it possible to obtain the broadest range of cultured pearl colours of any species. This study demonstrates the relative influence of using black [B] or red [R] outer shell phenotypes, combined with green [G] or yellow [Y] inner shell phenotypes, on pearl darkness level, colour categories and lustre. A large scale grafting experiment was designed and carried out over five grow-out locations, covering three archipelagos: Tuamotus, Society and Gambier. Results revealed that the [B + G] phenotypes may be used as donors to...

Trawling pressure and environmental changes may affect the composition of fish assemblages. Our knowledge on large spatio-temporal patterns of demersal fish composition remains incomplete for the Mediterranean Sea. We investigated (1) the spatio-temporal stability of demersal assemblages, (2) the relationships between these assemblages and potential structuring factors (trawling pressure and environmental conditions) in order to assess the dynamic of the assemblage structure at the scale of the northern Mediterranean Sea. We analysed a dataset of 18062 hauls from 10 to 800 m depth performed annually during the last two decades across 17 Geographical Sub-Areas (GSAs) (MEDITS program). A multi-table analysis (STATICO-CoA) evidenced a strong inter-GSAs...

Pattern of recruitment variability in the geographical range of the exploited northeast Atlantic fish species
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brunel, Thomas; Boucher, Jean.
It has long been argued that populations living on the edges of the species geographical range should exhibit stronger environmentally imposed variations in abundances than populations living near the centre of this range. This so-called 'Species Range Hypothesis' is tested here for the recruitment of 62 marine fish populations of the northeast Atlantic, belonging to 17 species. The pattern of increasing recruitment variability from the centre towards the edges of the species range was modelled by a quadratic linear regression between an index of interannual variability in recruitment and an index of population position in species range. The relationship between recruitment variability and exploitation rate was also investigated.   A wide range of...

Low pH reduced survival of the oyster Crassostrea gigas exposed to the Ostreid herpesvirus 1 by altering the metabolic response of the host
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fuhrmann, Marine; Richard, Gaëlle; Quere, Claudie; Petton, Bruno; Pernet, Fabrice.
Environmental change in the marine realm has been accompanied by emerging diseases as new pathogens evolve to take advantage of hosts weakened by environmental stress. Here we investigated how an exposure to reduced seawater pH influenced the response of the oyster Crassostrea gigas to an infection by the Ostreid herpesvirus type I (OsHV-1). Oysters were acclimated at pH 8.1 or pH 7.8 and then exposed to OsHV-1. Their survival was monitored and oyster tissues were sampled for biochemical analyses. The survival of oysters exposed to OsHV-1 at pH 7.8 was lower (33.5%) than that of their counterparts at pH 8.1 (44.8%) whereas levels of OsHV-1 DNA were similar. Energetic reserves, fatty acid composition and prostaglandin levels in oyster did not vary...

Cod (Gadus morhua) Migrations in the Gulf of St. Lawrence and Areas South of Newfoundland
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Moguedet, Philippe.
During the years 1975, 1976, 1980 and 1982 cod (Gadus morhua) tagging experiments were conducted, inside the Gulf of St. Lawrence and outside in areas south of Newfoundland, by French scientists from IFREMER St. Pierre and Miquelon laboratory, in order to study the population distribution and migration and to complement the experiments carried out by Canadian scientists. The analysis from all recoveries and results from these experiments are presented here. The relevance is that the comparison with the Canadian results would lead to a better understanding of the cod stock exchanges in the area. The migratory patterns were believed to be mainly a response to seasonal environmental condition changes. In winter the cod were noted to migrate from the central...

Previous pathological studies have not permitted to implicate infectious disease in summer mortalities of oysters Crassostrea gigas, in the Arcachon bay. In 1983, these summer mortalities, occurring mostly among 1 year old oysters, have been the subject of new investigations. In order to establish the causes of mortalities, oysters of the same origin were held in two areas characterized by different prevalence of mortality for 6 months, during which measurements of physiological and biochemical condition and certain histological observations were made. The study has been completed by environmental observations. Different rates of mortality appeared between the two selected areas: 30 %in Taussat in the upper part of the bay, under a continental influence...

The development of marine fish farming in europe : a parallel with salmon culture
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Harache, Yves; Paquotte, Philippe.
This paper is aimed at analysing the similar trends and different constraints which influence marine fish farming of new species such as sea-bass, sea-bream and turbot in Europe in comparison with the Norwegian salmon farming success. In a general context of low progression, European aquaculture has been characterised by the development of  intensive fish farming. The most notable fact is the recent increase in intensive salmonid farming,  with a turnover of almost 2 millions Ecu. More recently, the intensive farming of sea bass and sea bream has increased very rapidly in the Mediterranean Basin, although on a more reduced extent. Turbot farming is developing slowly too on the French and Spanish Atlantic coast, taking benefit of the temperate climate in...

Metabolism of the Pacific oyster,     Crassostrea gigas     , is influenced by salinity and modulates survival to the Ostreid herpesvirus OsHV-1
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fuhrmann, Marine; Delisle, Lizenn; Petton, Bruno; Corporeau, Charlotte; Pernet, Fabrice.
The Pacific oyster, Crassostrea gigas, is an osmoconforming bivalve exposed to wide salinity fluctuations. The physiological mechanisms used by oysters to cope with salinity stress are energy demanding and may impair other processes, such as defense against pathogens. This oyster species has been experiencing recurrent mortality events caused by the Ostreid herpesvirus 1 (OsHV-1). The objectives of this study were to investigate the effect of salinity (10, 15, 25 and 35‰) on energetic reserves, key enzyme activities and membrane fatty acids, and to identify the metabolic risk factors related to OsHV-1-induced mortality of oysters. Acclimation to low salinity led to increased water content, protein level, and energetic reserves (carbohydrates and...

Donor effect on cultured pearl nacre development and shell matrix gene expression in Pinctada margaritifera reared in different field sites
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ky, Chin-long; Broustal, Floriane; Koua, Manaarii Sham; Quillien, Virgile; Beliaeff, Benoit.
Understanding the respective roles played by donor and recipient pearl oysters in pearl quality determination in relation to the environment is a challenge for the pearl industry. In most Pinctada species, pearl size is mainly related to recipient oyster growth performance, but also relies to some extent on the biomineralisation activity of the pearl sac, a tissue that originates from the donor oyster mantle. We examined donor effect on pearl size in response to culture in the lagoons on Arutua and Apataki atolls. Overall nacre weight and thickness were greater in Arutua than in Apataki, but sensitivity to the environment differed between donors. Some donors were associated with significantly heavier and thicker nacre in Arutua (I group), while others had...

Autores: Saffache, P.
The progradation of the shores of the Gallon Bay (Martinique) has been measured based on diachronic mapping analysis. The sedimentary volume which accumulates along the coast and in the bay (under the water surface) is unknown. Erodibility has been surveyed on a square meter scale and extrapolated to the watersheds. The results show that most sediments originate from the farmed surfaces, they are then entrained by the runoff and the Gallon river and deposited along the coast, where the bathymetry and currentology of the bay facilitate sediment retention. The harmful effects of anthropogenic influence in the area are discussed.

Scientific programming in environmental science often relies on short-term (3 to 5 years) trend-based projections for contextual elements like the demography or the economy to construct or justify its choice of priorities. However, this approach does not take into account numerous factors of change or disruption over a longer term (10 to 20, or even 50 years), although a decade or two are needed to effectively deal with the stakes of research. These stakes become more acute over the long term, as consequences of predicted changes (e. g. climate) or other factors such as pollution, biodiversity erosion, reduction of ecosystemic services.... This complex question justifies turning to a foresight approach. Because it enables tipping points to be envisaged for...

In French Polynesia, the aquaculture of P. margaritifera is carried out in numerous grow-out sites, located over three archipelagos (Gambier, Society and Tuamotu). To evaluate the impact of macro-geographical effects of these growing sites on pearl quality traits, five hatcheries produced families were used as homogeneous donor oysters in an experimental graft. The molluscs were then reared in two commercial locations: Tahaa island (Society) and Rangiroa atoll (Tuamotu). At harvest, eight pearl quality traits were recorded and compared: surface defects, lustre, grade, circles, shape categories, darkness level, body and secondary colour and visual colour categories. Overall inter-site comparison revealed that: 1) all traits were affected by grow-out...

Autores: De Fries,Lucas; Rosa,Gilberto da; Silva,José Pezzi da; Vilella,Fábio Silveira; Becker,Fernando Gertum.
ABSTRACT Fish reproduction in floodplain rivers is often linked to flow regime and with the inundation of floodplain habitats. However, in confined rivers, where floodplains are absent, the relation between reproduction and flow can in comparison be expected to be distinct. In this study, we describe the reproductive life-history of Hemiancistrus fuliginosus and Hypostomus isbrueckeri in a confined river and discuss its differences relative to floodplain loricariids and also the implications for effects of dam construction and flow regulation. We found the reproductive peak of both species occurred during lowering waters, just after maximum river flow, in contrast to floodplain species that tend to spawn during rising waters. The studied species presented...

L’étude porte sur l’exploitation, la biologie et la dynamique du poulpe (Octopus vulgaris, Cuvier) des eaux mauritaniennes. La répartition spatio-temporelle dans la région du Cap Blanc ne semble être liée ni à la taille, ni au sexe, mais varie au cours de l’année. L’analyse de l’état actuel de la pêcherie basée sur les congélateurs céphalopodiers met en évidence une augmentation de l’effort de pêche et la poursuite de chute des p.u.e. La composition des captures révèle une progression du pourcentage des individus de poids inférieur à 200 grammes (« poulpo »). L’étude biologique montre qu’il existe deux saisons de reproduction par an (mai-juillet et septembre-novembre) qui engendrent deux recrutements, l’un en mai et l’autre à partir de septembre. La...

Autores: Emara, H.I.; El-Deeb, M.K.Z.
Polycyclic aromatic hydrocarbons (PAHs), the real contaminants of petroleum, were detected in the surface seawater of Alexandria coastal area in winter and spring seasons of 1995. Their order of predominance, particularly for the individual components were principally due to the processes of input, transport and fluxes. Variation of PAHs was not following seasonal changes but it was slightly affected by partial dissolution of the lowerboiling aromatic hydrocarbons. The most abundant component of aromatic hydrocarbons was pyrene (PAH),112ngI-1 followed by naphthalene(56ngI-1) and its alkylated derivatives (dicyclic), then phenanthrene(14ngI-1) and its methylated derivatives (tricyclic). The potential fish carcinogenic PAH, dibenz [a &amp; c] anthracene was...

Heat and salt storages in the offshore water of the Red Sea
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Kamel, M.S.; Eid, F.M.
The seasonal changes of heat and salt storages in the offshore water of the Red Sea were studied using a historical data collected from different cruises during the period from 1924 to 1998. The heat storage within water column of different depths exhibits a seasonal variability. The heat storage is low during winter and high during summer. Also, the heat storage increases from north to south. The maximum values of heat storage are found in the southern central part of the Red Sea. It reached about 29.9x109 J/m2 within the water column of 300m depth. The seasonal change of heat storage from the annual mean is negative during winter and spring, while it is positive during summer and autumn. It has higher values during winter and summer, while its value...

Inception Report The Preparatory Survey on the Project for Fisheries Pormotion in Republic of Ghana
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ghana Ports and Harbours Authority.
Challenges the fishing ports of Ghana, notably Sekondi Port include the congestion and the deteriorating efficiency due to the increase of users and decreasing quality of catch due to the shortage and ageing of landing facilities, fish handling sheds and ice-making facilities. The Government of Ghana made a request to Japan for an extension of the wharf, construction of additional breakwater, cold storage and ice-making facility at Sekondi Fishing Port in 2010 in order to overcome these challenges. In response the Government of Japan conducted a survey for the project to promote efficiency and improvement of Ghana's fishery sector. The survey was to examine the need, relevance and urgency of the proposed project.

Pre-concentration and separation of Fe (III), Co (II), Ni (II) and Zn (II) by solid-phase extraction using silica modified with N-propylsalicylaldimine
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Hamed, M.A.
N- propylsalicylaldimine based on porous silica, as ion exchanger, was used for the separation and preconcentration of Fe3+, Co2+, Ni2+ and Zn2+ from surface water samples collected from eleven locations at Nile river, Mediterranean and Red seas as well as tap water of Mansoura city. The effects of pH value, time of stirring, concentration of eluting acids and some common ionic species on the separation and preconcentration of the investigated metal ions in synthetic aqueous solutions were studied. The results indicate that the optimum conditions for separation are pH = 9.0-9.5 and time of stirring = 30 min. HCl is better eluent for the investigated metal ions than HNO3 except for Fe3+. Citrate and EDTA gave severe interference on the recovery of the metal...

Enhancing environmental awareness through marine education
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Collins, M.A.J.
Throughout this colloquium reference has been made to a number of environmental problems, most of them due to human activities (e.g. clearing mangrove forests, dynamite fishing, sewage pollution, etc.). While attempts are being made to correct these problems through new legislation and educating adults in more environmentally friendly practices, it is my thesis that we should be putting much more effort into the environmental education of young, school-age children since such efforts will, in the long run, have the greater impact on environmental awareness.

The work of the media in whale strandings
Provedor de dados: Open Marine Archive
Autores: Noël, L.
The stranding of sperm whales at the Belgian coast in November 1994 attracted the general attention of the media. Excessive shows of passion often encountered in other parts of the world when cetaceans die, were not observed. An examination of the articles which appeared in the press shows that the event was merely treated as a major, but common news item. Priority was given to the daily developments. The work of the authorities and that of the scientists were given similar status as the anecdotic aspects. The importance given to controversies regarding the management of the situation must be stressed. The media did not go deeply into the biology of sperm whales, the stranding that occurred abroad, or the various hypotheses that were discussed. How could...

Abstract: The objective of this work was to compare uni- and multivariate biometric methods to evaluate the adaptability and stability of an important group of white oat (Avena sativa) cultivars grown in Southern Brazil. The used experimental design was a randomized complete block, in a factorial arrangement of 12 environments x 7 cultivars, with three replicates. The analysis of variance and the methods of Eberhart &amp; Russel, Annicchiarico, and the harmonic mean of the relative performance of predicted genetic values (MHPRVG) were assessed. In the general comparison of the methods, the 'UPFA Gaudéria' and 'URS Guapa' genotypes were more stable regarding grain yield. The 'UPFA Gaudéria' and 'URS-21' genotypes stood out for hectoliter weight, presenting...

How Do Public Disclosure Pollution Control Programs Work? Evidence from Indonesia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Afsah,   Shakeb; Blackman,   Allen; Ratunanda,   Damayanti.
Although a growing body of evidence suggests that publicly disclosing information about plants' environmental performance can motivate emissions reductions, this phenomenon remains poorly understood. To help fill this gap, this paper presents original data from a survey of plants participating in the Program for Pollution Control, Evaluation and Rating (PROPER), Indonesia's widely-acclaimed public disclosure program. These data suggest that a key means by which PROPER spurs abatement is improving factory managers' information about their own plants' emissions and abatement opportunities. This finding contrasts with the prevailing view in the literature that public disclosure enhances pressures to abate placed on firms by external agents such as community...

Environmental Policy, Education and Growth: A Reappraisal when Lifetime Is Finite
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pautrel,   Xavier.
This article demonstrates that when finite lifetime is introduced in a Lucas (1988) growth model, the environmental policy may enhance growth both in the short- and the long-run, while pollution does not influence educational activities, labor supply is not elastic and human capital does not enter the utility function. This is because finite lifetime and the appearance of newborns at each date creates a turnover of generations which disconnects the aggregate consumption growth to the interest rate. We show that the shorter is the horizon, the greater the effect of the environmental policy on growth, because the higher the “generational turnover effect”. We also demonstrate that when time is not the single production factor in education, the environmental...

On the Implications of Technological Innovation for Environmental Policy
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parry,   Ian W.H.
This paper draws on a number of recent studies to shed light on several policy issues raised by the impact of environmental policies on technological innovation. First, to what extent does induced innovation raise the overall net benefits to society from environmental policies? Second, how does induced innovation affect the appropriate choice among alternative environmental policy instruments? Third, how does it affect the optimal stringency of environmental regulations? Fourth, should environmental policies be supplemented with additional policies to promote innovation, such as research contracts or prizes for new technologies?

Analysing options for the Red Gum Forests along the Murray River
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bennett,   Jeffrey W.; Dumsday,   Robert G.; Gillespie,   Robert.
The Victorian Environmental Assessment Council is conducting an investigation into the management of the public land River Red Gum Forests of the Murray River Valley in Victoria. In this paper the authors apply the results of an earlier Choice Modelling exercise commissioned by VEAC to estimate the non-use values of the forests. A Benefit Cost Analysis of VEAC's draft recommendations included assessment of the market and non market values associated with different River Red Gum forest management strategies. It is concluded that the use of water for environmental flows is competitive with its use for irrigation. Other economic values associated with timber harvesting, grazing and duck hunting are small in comparison with the water values.

An experimental study of wine consumers’ willingness to pay for environmental characteristics
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bazoche,   P.; Deola,   C.; Soler,   Louis-Georges.
The reduction of pesticides use is becoming a priority for the public authorities in many countries. We conducted an experiment with wine consumers to see whether end-consumers value the dissemination of information about environmentally-friendly production practices. The experiment was devised to (i) evaluate whether there is a premium for environmentally-friendly wines, (ii) determine whether or not consumers are sensitive to label owners who implement and guarantee the environmental actions, (iii) and assess the impact of public messages about the consequences of pesticide use. Some 139 participants were divided randomly into two groups. One group had no specific information about the current state of pesticide use in farming. The other group was given...

Colombia's Discharge Fee Program: Incentives for Polluters of Regulators?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen.
Colombia's discharge fee system for water effluents is often held up as a model of a well-functioning, economic-incentive pollution control program in a developing country. Yet few objective, up-to-date evaluations of the program have appeared. Based on a variety of primary and secondary evaluative data, this paper finds that that the program has been beset by a number of serious problems including limited implementation in many regions, widespread noncompliance by municipal sewage authorities, and a confused relationship between discharge fees and discharge standards. Nevertheless, in several watersheds, pollution loads dropped significantly after the program was introduced. While proponents claim the incentives that discharge fees created for polluters...

Autores: Clay,   Daniel C.; Reardon,   Thomas.
The triple challenge of rapid population growth, declining agricultural productivity, and natural resource degradation are not isolated from one another; they are intimately related. However, strategic planning and development programming tend to focus on individual sectors such as the environment, agriculture, and population; they do not explicitly take into account the compatibilities and inconsistencies among them. Farm households and their livelihood strategies are at the core of the intersectoral linkages approach advocated in this chapter. Three key aspects of the population-environment-development debate are discussed: first, the finding that inconsistencies between public and individual household behavior regarding childbearing and family planning...

Autores: Kipperberg,   Gorm; Bond,   Craig A.; Hoag,   Dana L.
This paper analyzes Colorado Corn producers’ preferences over both private- and environmental public-good production system attributes. Current production practices are characterized by intensive water and chemical use, resulting in non-point source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations find positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The results also find presence of significant preference heterogeneity and a complementary...

The agriculture has an outstanding importance both in social and economic point of view, especially in the countries where the agriculture plays a vital role in economy. This paper mainly focuses on the situation in the Central and Eastern European countries (CEECs). The share of agriculture in CEECs is more significant both in GDP and employment than in the old member states of EU. To be competitive on the single market, we have to know the advantages and disadvantages, strength and weakness of different sectors of agriculture. Traditionally, in these countries to measure the effectiveness, the partial factor analyses are used. To get more accurate overview, we need to use more wide technique to sampling measurement. This paper summarizes the measurement...

Investing in Livestock Development in Water-Scarce Semi-Arid Watersheds: Technological, Institutional and Policy Dimensions
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Puskur,   Ranjitha.
Watershed Development Programmes (WDPs) in India were conceived as tools for correcting the regional imbalances in agricultural development created by Green Revolution, through investments in soil and water conservation (SWC) and natural resource management (NRM) in rainfed areas. Though the overall impact of WDPs has been positive and significant, with increase in physical and economic access to groundwater, landless and marginal households hardly benefited from watershed development. Recent evidence points out that in many watersheds inequities increased, since for non-land owning and -well owning households access to drinking water, grazing lands and other natural resources decreased. This paper is based on a research project carried out by the...

Efficiency of a Biofuel Subsidy Policy in the Presence of Environmental Externalities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bayramoglu,   Basak.
The object of this paper is to analyze, in a general equilibrium setting with four markets, the efficiency of a biofuel subsidy policy. The analysis takes into account environmental externalities associated both with the production and the consumption of biofuels, as well as associated with the production of agricultural raw material. Our preliminary numerical results, applied to the biodiesel subsidy policy in France, first show that this policy increases the utility of the representative consumer compared to the laissez-faire solution. The same policy action leads, however, to an increased level of agricultural and GHG emissions, in comparison with the laissez-faire solution.

Why farmers continue to use pesticides despite environmental health and sustainability costs
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Use of chemical inputs such as pesticides have increased agricultural production and productivity.  However, negative externalities, too, have increased.  The externalities include damage to the environment, agricultural land, fisheries, fauna and flora.  Another major externality has been the unintentional destruction of beneficial predators of insects which has led to a virulence of many species of agricultural pests.  Mortality and morbidity among agricultural workers, especially in developing countries from exposure to pesticides, are also common.  The costs from these externalities are large and affect farmers’ returns.  However, despite these high costs, farmers continue to use pesticides and in increasing quantities.  In this paper, we examine this...

Cross-Border Environmental Management and the Informal Sector: The Ciudad Juarez Brickmakers' Project
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen; Bannister,   Geoffrey J.
The considerable difficulties associated with cross-border environmental management are compounded when polluters are unlicensed micro-enterprises such as auto repair shops and traditional brick kilns; such "informal sector" firms are virtually impossible to regulate in the conventional manner. This paper describes an example of an innovative and promising approach to the problem: the Cd. Juarez Brickmakers' Project, a private-sector-led, binational initiative aimed at abating highly polluting emissions from Cd. Juarez's approximately 350 informal brick kilns. We draw three lessons from the Project's history. First, private-sector-led cross-border initiatives can work -- indeed they may be more effective than public sector initiatives -- but they require...

Autores: Toma,   Luiza; Ashworth,   Cheryl J.; Stott,   Alistair W.
This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates the effects of animal welfare changes on the pig production systems (pig meat) and further on trade flows (trade in pig meat) and environment (water and air pollution). We consider two animal welfare simulation scenarios, namely the status quo – no animal welfare change as regards pig neonatal mortality (baseline scenario) and the case of improving pig neonatal survival (alternative scenario) and compare the impacts on trade and environment between the two...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: MacAuley,   Molly K.
The lay of the policy land for addressing and managing environmental risk includes the hillock of the precautionary principle, the mountain of the practice and ethics of monetary valuation, and the tectonic plates of real-world innovations in markets and trading exchanges for nonmarketed environmental goods. This paper offers an overview of these contemporary and as yet unresolved issues and asks how each might be addressed in disparate environmental risks such as lightning, climate change, and severe weather. The overview focuses on issues that may be of interest to the American Meteorological Society's annual policy colloquium.

NAFTA's investment treaty has led to several expropriation compensation claims from investors hurt by new environmental regulations. Expropriation clauses in international treaties solve post-investment moral hazard problems such as hold-ups. However, these clauses can interact with National Treatment clauses in a manner that hinders investment. A police powers carve-out from the definition of expropriation can be Pareto-improving and can increase the level of foreign investment.

Macroeconomic Implications of Demography for the Environment: A Life-Cycle Perspective
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pautrel,   Xavier.
This article studies how demography affects the outcome of the environmental policy in a macro-economic perspective, incorporating age-earning profiles in an OLG model à la Blanchard (1985) to capture the age structure effect of the demographic shocks. It first demonstrates, conversely to previous works of the related literature that a decrease in the birth rate may lower the steady-state per capita stock of physical capital even if the aggregate labor supply is exogenous. It also demonstrates that the ageing of population influences the macro-economic impact of the environmental policy according to the cause of the ageing and the life-cycle earnings assumption. Thus, with decreasing age-earning profiles, a lower birth rate reduces the detrimental impact...

However, a new low-salinity shrimp farming system has developed that seems to have fewer disease and environmental problems than previous systems but competes with rice production for land and water resources.  The present study found that shrimp farming exhibits increasing returns to scale and is much more profitable than rice farming, which offers opportunities for rice farmers to improve their incomes through diversification.  No evidence was found for external environmental effects of shrimp production on rice production or vice versa.  A total ban on shrimp production in rice farming areas...

Autores: Dargatz,   David.
The NAHMS Beef '97 Study was designed to provide both participants and the industry with information on the nation's cow-calf population for education and research.  The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically-valid sample yielding 2,713 producers from 23 states.  The 23-state target population represented 85.7 percent of U.S. beef cows on January 1, 1997, and 77.6 percent of U.S. beef operations.  Federal and state Veterinary Medical Officers (VMO's) and Animal Health Technicians (AHT's) collected data for this report on-farm from March 3, 1996, through May 23, 1997, from 1,190 operations that had five or more beef cows on January 1, 1997.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brookins,   Carole L.
The world is producing greater opportunity for more people than ever before in the history of mankind. The global agri-food system is dynamic, not static. In order to understand the future trends and potentials for utilizing and improving our agri-food system, it is critical to focus on forces that will improve both productivity and policy to meet the demands of the ever-changing global market. This paper identifies five major trends that will impact the global economy and create structural change in commodity markets.

RISK, GOVERNMENT PROGRAMS, AND THE ENVIRONMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roberts,   Michael J.; Osteen,   Craig D.; Soule,   Meredith J.
Nearly all farm business ventures involve financial risk. In some instances, private and public tools used to manage financial risks in agriculture may influence farmers' production decisions. These decisions, in turn, can influence environmental quality. This bulletin summarizes research and provides some perspective on private and public attempts to cope with financial risks and their unintended environmental consequences. Specifically, it examines the conceptual underpinnings of risk-related research, challenges involved with measuring the consequences of risk for agricultural production decisions, government programs that influence the risk and return of farm businesses, and how production decisions influence both the environment and the risk and...

The Environmental Impacts of Electricity Restructuring: Looking Back and Looking Forward
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Palmer,   Karen L.; Burtraw,   Dallas.
In the mid-1990s, when the Federal Energy Regulatory Commission was preparing to release Order 888 requiring open access to the transmission grid, the commission, environmental groups, and the Environmental Protection Agency, among others, raised the question of how open access and greater competition in wholesale electricity markets might affect the environment. If open access worked as expected, underutilized older coal-fired generators in the Midwest and elsewhere might find new markets for their power, leading to associated increases in air pollution emissions. Restructuring also might lead to retirements of inefficient nuclear facilities, whose generation would be replaced by fossil generation, further increasing emissions. On the other hand, some...

Recursive Sustainability: Intertemporal Efficiency and Equity
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Knapp,   Keith C.
PV-optimality in a capital-resource economy can imply decreasing utility over some portion of the time horizon. Various criteria have been proposed to maintain intergenerational equity defined as nondeclining utility, but these have some limitations and problems. This paper proposes a new welfare criteria incorporating present value to maintain efficiency, and an equity function with convex costs on declining utility. This criterion is economically efficient, time-consistent and recursive. An extension of dynamic programming to multiple value functions is developed to solve this problem. Increasing the equity weight increasingly eliminates declining portions of utility time paths. Sustainability implies increasing consumption in the early time periods and...

POLITICS AND MARKETS IN THE ARTICULATION OF PREFERENCES FOR ATTRIBUTES OF THE RAPIDLY CHANGING FOOD AND AGRICULTURAL SECTORS: FRAMING THE ISSUES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abdalla,   Charles W.; Shaffer,   James D.
Industrialization of the food and agricultural sectors changes the pattern of external effects. Participants helped or harmed in the process attempt to influence outcomes through markets and politics.  Decisions about property rights and boundaries determine benefits and burdens and the relative cost of animal agriculture in different jurisdictions.  Prescriptions to redefine property rights are influenced by selective perception of rights to share in the benefits and be protected from costs.  Political choices about the appropriate jurisdiction (state versus local) for addressing environmental and nuisance effects of animal agriculture affect whose preferences count and will influence the development of these sectors.

We examine whether the use of the environment, proxied by CO2 emissions, as a factor of production contributes, in addition to conventional factors of production to output growth, and thus it should be accounted for in total factor productivity growth (TFPG) measurement and deducted from the .residual. A theoretical framework of growth accounting methodology with environment as a factor of production which is unpaid in the absence of environmental policy is developed. Using data from a panel of 23 OECD countries, we show that emissions. growth have a statistically significant contribution to the growth of output, that emission augmenting technical change is present along with labor augmenting technical change, and that part of output growth which is...

This paper studies firms’ incentives to invest in environmental R&amp;D under different market structures (Cournot and Bertrand) and environmental policy instruments (emission standards, taxes, tradable permits and auctioned permits). Because of market strategic effects, R&amp;D incentives vary widely across market structures and instruments. For example, when firms’ products are strategic substitutes (i.e., Cournot), either emission standards, taxes or auctioned permits can provide the most incentives. But when firms’ products are strategic complements, either taxes or auctioned permits provide the most incentives. If markets are perfectly competitive, however, permits and emission standards offer similar incentives that are lower than those offered by...

This study examined the size and the determinants of the price premium a sample of Edmonton-area consumers was willing to pay for organic wheat bread. The development of these premiums included consideration of providing information on health or environmental advantages of organic production and consideration of sensory (taste) acceptance. To do this conventional and organic wheat was grown under similar conditions and milled and baked into 60% whole wheat bread under identical conditions. Samples of these breads were presented to consumers for sensory acceptance and a survey of their attitudes, behaviours and characteristics. The survey included a closed-ended contingent valuation question to examine consumers' willingness-to-pay (WTP) premiums for the...

Environmental Issues of Agriculture: Social Perception Analysis in Southern Spain
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Salazar-Ordonez,   Melania; Sayadi,   Samir.
Agriculture largely shapes the European ecosystems. Today the environmental social interest and the awareness that some farming practices destroy the natural environment is undeniable. Thus, the European decision maker’s emphasis on integrating social demands within the Common Agricultural Policy becomes unquestionable. In this context, this paper analyses: i) the degree of social compliance with soilerosion control from agriculture in Andalusia (southern Spain); ii) the degree of society’s concern about its agriculture; and iii)the respondent’s features that influence both perceptions.

We review the legal provisions of the WTO regime that have important implications for national, market-based environmental policies. We evaluate those provisions for their effects on a member country's ability and incentives to design economically efficient environmental policies. International trade institutions do not recognize the polluter pays principle, posing some challenges for unilateral policies addressing cross-border pollutants and leakage. Nor do they recognize the economic equivalence of emission tax and permit regimes, leading to different potential constraints on policy design and leaving some environmental policies open to influence by protectionist motives. As many legality issues have yet to be disputed and resolved, opportunities exist...

In Honduras, traditional coffee processing is the cause of two major problems: poor coffee quality and contaminated water.  In this paper we present a method that determines the trade-off between economic efficiency and contamination in a Honduran sub-watershed.  The method is a bioeconomic model based on mathematical programming that stimulates the functioning of the interlinked economic and ecological processes in the sub-watershed.  We compare various scenarii where the model is given the possibility of replacing traditional coffee processing plants with a network of improved ecological plants.  For different levels of contamination the model determines the optimal location and size of new coffee processing plants along river streams by minimizing...

Greener Acres or Greener Waters? Potential U.S. Impacts of Agricultural Trade Liberalization
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johansson,   Robert C.; Cooper,   Joseph C.; Vasavada,   Utpal.
This paper examines the elimination of all agricultural policy distortions in all trading countries and agricultural production decisions in the United States, as well as subsequent environmental quality in the presence and absence of nondegradation environmental standards. The results suggest that trade liberalization has the potential to increase domestic production and boost agricultural returns by as much as 8.5 percent. Consumer surplus would likely fall, and the discharge of nutrients, sediment, and pesticides would likely increase. However, environmental policies can limit these adverse environmental impacts and mute the potential decrease in consumer surplus, while leaving increased returns to agricultural production.

Risky Activities and Strict Liability Rules: Delegating Safety
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mondello,   Gerard.
This paper studies the delegation of activities that pose serious risks to health and the environment in an economy regulated by strict liability schemes. Strict liability induces judgment-proof possibilities. Two civil liability regimes are then compared: a strict liability scheme and a capped strict liability one. The argument is led under a twofold asymmetric information assumption between the principal and the agent: the efficiency level in effort for safety and the agent’s level of wealth. The paper shows that standard strict liability under information asymmetries deters the efficient agent to compete and favors adverse selection. Then, under conditions, a capped strict liability regime is a better regime than a standard strict liability one because...

Market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies. These combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology. Both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives, and can be cost-effectively harnessed through the use of economicincentive based policy. In the presence of weak or nonexistent environmental policies, investments in the development and diffusion of new environmentally beneficial technologies are very likely...

The introduction of renewable biofuels was associated with global food crisis and unintended environmental consequences. This paper incorporates energy environment and agricultural sector to the classic Hecksher-Ohlin model to address these issues. A household production function model was introduced to model consumer energy choices and concern about externalities related to climate change and open space. The conceptual model links energy and food markets and derives guidelines for the development of climate change and land-use policies. The results suggest that globalization and capital  flows increase demand for energy, leading to decline in food production, increase in food prices, and loss of environmental land. Globally optimal outcomes may require...

Compliance with the principles of sustainability is now a general requirement with respect to any tourism strategy, tourism policy or management. Much has been written about the issue of sustainability and its relationship to tourism management and development. Still, their actual relationship is not always clear, and whilst a number of methodologies profess to be sustainable, there is no clear statement as to how that can be achieved. It is generally accepted, irrespective of the sustainability model used, that there are three key components or strands to sustainability: economic, social and environmental. It is in working towards a balance between the competing demands of all three components that progress towards sustainability can be achieved. One...

Metrics for evaluating environmental trade-offs can be developed with varying levels of consistency across case study sites. A key issue is whether standard evaluation experiments can be conducted over multiple sites, or whether experiments have to be tailored to each case study application. To test how useful a consistent approach is, choice modelling (CM) has been used in a number of countries. Choice modelling assess the trade-offs households are prepared to make between water use restrictions, maintaining environmental conditions in waterways, and increased water costs.   This research paper reports the results of the Queensland survey. The results show that it is not possible to downplay case study framing issues and that it is not appropriate to...

Hazardous Activities and Civil Strict Liability: The Regulator’s Dilemma
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mondello,   Gerard.
This paper addresses the conditions for setting up strict civil liability schemes. For that it compares the social efficiency of two main civil liability regimes usually enforced to protect the environment: the strict liability regime and the “capped strict liability scheme”. First, it shows that the regulator faces an effective dilemma when he has to enforce one of these schemes. This because the social cost of a severe harm (and the associated optimum care effort) is determined independently of any liability regime. This independency has economic consequences. First, victims and polluters pit one against another about the liability regime that the government should enforce. Hence, financially constrained polluters prefer the ceiling of responsibilities...

Policy makers and policy analysts are frequently faced with situations where it is unclear whether market-based instruments hold real promise of reducing costs, relative to conventional command-and-control approaches. We develop rules-of-thumb that can be employed with minimal amounts of information to estimate the potential cost savings associated with marketbased policies, with an application to the environmental policy realm. Our hope is that these simple formulae can aid policy analysts and policy makers in the early stages of exploring alternative policy instruments by helping them identify approaches that merit greater attention and more detailed analysis. We illustrate the use of the rules-of-thumb with an application to nitrogen oxides control in...

The cost of meeting environmental regulations can be a critical factor in determining the competitiveness of a product, since the cost advantages of producers in one country are often very slim. The existence of negative externalities means that prices are lower than would prevail if all costs where included in the prices of the products. Additional costs associated with new regulations have an effect on the continued importance of a country's agricultural exports. Governments often assist their agricultural sectors in overcoming the disadvantages through subsidies, tax breaks, technical assistance or other means. This assistance increasingly takes the form of green payments, which are currently exempt from the WTO limits imposed on domestic subsidies....

Environmental Provisions in Recent Regional Trade Agreements (2008 &amp; 2009)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Colyer,   Dale.
Despite a failure to achieve closure on the Doha Round of WTO negotiations, regional and bilateral trade agreements involving a variety of countries have continued to be negotiated, signed and implemented. Most of the recent trade agreements have contained some environmental provisions, ranging from a pledge to protect the environment to very extensive environmental requirements. These results appear to reflect a recognition that trade has environmental consequences and that trade agreements can be constructed to help mitigate such effects.

Precaution: principles and practice in Australian environmental and natural resource management
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Peterson,   Deborah C.
Since the late 1980s, the concept of precaution has been incorporated into numerous international agreements and laws, as well as in domestic statutes and policies in many countries. This paper examines the international emergence of the concept and its application in Australia. Despite rapid growth in adoption of the so-called ‘precautionary principle’, the concept remains highly controversial, and its success in terms of improving environmental and natural resource management has been questioned. A common misconception is that the principle prescribes action. In fact, internationally accepted definitions are about decision-making processes. This paper argues that implementation guidelines are essential to ensure that precautionary decision-making is...

MEASURING THE ENVIRONMENTAL IMPACTS OF TECHNICAL PROGRESS IN LOW-INCOME AGRICULTURE: EMPIRICAL EVIDENCE ON IRRIGATION DEVELOPMENT AND FOREST PRESSURE IN PALAWAN, THE PHILIPPINES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Shively,   Gerald E.
Data from the Philippines are used to measure impacts of technical progress in lowland agriculture on upland forests. Irrigation development, labor demand, and employment are studied. Total annual labor use increased following irrigation.  Employment of household members living along forest margins increased also. Time allocation data from the uplands show that increases in employment among households living along the forest margin were accompanied by reductions in forest clearing and forest-degrading activities.  Empirical findings show irrigation-induced increases in agricultural employment can reduce pressure on tropical forests.  Implications for policies and trends in use of labor saving methods that could undermine the observed changes are discussed.

Analysis of Environmental and Economic Efficiency: Application of the Overseer model and simulated data
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ramilan,   Thiagarajah; Scrimgeour,   Frank G.; Marsh,   Dan.
New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

A Multicommodity EU Policy Framework Incorporating Public Good Criteria into the Direct Payment System in Agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dunne,   W.; O'Connell,   J.J.
For decades the CAP has been the major influence in shaping EU agriculture and food production. The economic and policy environment in the EU is now very different from that which prevailed in the earlier decades. The future economic, social and geographic diversity of the EU will be further increased by enlargement. Agricultural policies and the related operational frameworks will inevitably change to accommodate this added diversity and the changing societal and consumer values. This paper evaluates how the current shape of EU agriculture has been influenced by the reforms to date. It also attempts to focus on where EU farming may be, or wish to go, over the next decade. The evaluation is restricted to the beef sector as it has been to the forefront in...

Agriculture and Environmental Issues in Free Trade Agreements
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Colyer,   Dale.
Including environmental issues in trade agreements is controversial, although these issues are an integral part of the NAFTA and WTO agreements as well as being the subject of numerous multilateral environmental treaties and agreements. Despite its inclusion, many members are opposed to allowing the environment an extensive role in the WTO. Nonetheless, the Doha Ministerial Declaration recognizes the environment in negotiating the next trade liberalization agreement. Agriculture and agricultural trade, which were integrated with international trade disciplines in the Uruguay Round, have environmental implications, and the inclusion of agriculture in the WTO introduces complex issues that also have environmental consequences.

Autores: Baek,   Jungho; Koo,   Won W.
The cointegration analysis and a vector error-correction (VEC) model are applied to examine the short- and long-run relationships among foreign direct investment (FDI), economic growth, and the environment in China and India. The results show that FDI inflow plays a pivotal role in determining the short- and long-run movement of economic growth through capital accumulation and technical spillovers in the two countries. However, FDI inflow in both countries is found to have a detrimental effect on environmental quality in both the short- and long-run, supporting pollution haven hypothesis. Finally, it is found that, in the short-run, there exists a unidirectional causality from FDI inflow to economic growth and the environment in China and India - a change...

Location differences in communities’ preferences for environmental improvements in selected NSW catchments: A Choice Modelling approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mazur,   Kasia; Bennett,   Jeffrey W.
To elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean), a choice modelling (CM) study was conducted.  This report presents results of research designed to investigate variations in WTP across different communities. The communities included local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effects’. The analysis involved both conditional logit and random-parameters logit models.   Natural resource management (NRM), including Catchment Management Authorities (CMAs), can use the non-market values obtained from this study to guide their investment decisions.

The Impact of Environmental and Health Motivations on the Organic Share of Produce Purchases
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Durham,   Catherine A.
As demand and supply of organic produce has increased, it has become possible to distinguish between the many individuals that express a preference for organic and the share of their purchases that is organically produced. This study examines the share of a consumer’s produce purchases that are organic, and how that is influenced by economic factors, environmental and health motivations, and demographic characteristics. Results from a model of organic preference are compared to those from a model of organic buying proportions. Buying proportion models are also estimated separately for those that preferred organic and those that preferred conventional produce. A limitation in this study is that it evaluates stated buying proportions rather than actual...

Agri-environmental conservation – the case for an environmental levy
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Crean,   Jason.
Recent environmental assessments have highlighted the extent of land degradation in Australia and the significant costs involved in addressing it. With projected investment costs running into tens of billions of dollars, it is not surprising that greater attention is now being focussed on who should pay. One idea gathering significant momentum has been the imposition of an environmental levy. Such a levy would raise public funds to be spent on resource degradation issues and has been proposed to work through the taxation system in a similar fashion to the Medicare levy, albeit for a more limited 10 year period. The paper assesses the arguments behind the imposition of an environmental levy and considers some of the issues associated with its effective...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roberts,   Roland K.; Mahajanashetti,   S.B.; English,   Burton C.; Larson,   James A.; Tyler,   Donald D.
Meta-response functions for corn yields and nitrogen losses were estimated from EPIC-generated data for three soil types and three weather scenarios.  These metamodels were used to evaluate variable rate (VRT) versus uniform rate (URT) nitrogen application technologies for alternative weather scenarios and policy option.  Except under very dry conditions, returns per acre for VRT were higher than for URT and the economic advantage of VRT increased as realized rainfall decreased from expected average rainfall.  Nitrogen losses to the environment from VRT were lower for all situation examined, except on fields with little spatial variability.

Autores: Chalak,   Morteza; Pannell,   David J.
Weeds can cause significant problems to natural ecosystems. Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. This paper addresses this gap in the literature by assessing the cost-effectiveness of a comprehensive range of control strategies for blackberry (Rubus anglocandicans) in natural environments in Australia. We developed a stochastic dynamic simulation model and a deterministic dynamic optimisation model. The stochastic model calculates the expected net present value (NPV) of a range of control strategies, including any combination of treatment options. The optimisation model identifies the treatment combination that maximises NPV. Both models represent the...

The Free Trade Area of the Americas (FTAA), a free trade area under negotiation among the United States and 33 countries in the Western Hemisphere, will progressively liberalize trade and investment in the region. It is scheduled to become effective by the end of 2005. The FTAA will lead to a 6-percent increase in annual U.S. agricultural exports to the Hemisphere and a 3-percent increase in annual U.S. agricultural imports from the Hemisphere. The FTAA will increase annual U.S. agricultural exports and imports worldwide by about $1 billion each. The expansion of U.S. agricultural trade due to the FTAA will result from both the direct effect of trade liberalization and the indirect effect of accelerated economic growth in increasing agricultural demand in...

Autores: Acemoglu,   Daron; Aghion,   Philippe; Bursztyn,   Leonardo; Hemous,   David.
This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed to improving the technology of machines in either sector. We characterize dynamic tax policies that achieve sustainable growth or maximize intertemporal welfare. We show that: (i) in the case where the inputs are sufficiently substitutable, sustainable long-run growth can be achieved with temporary taxation of dirty innovation and production; (ii) optimal policy involves both “carbon taxes” and research subsidies, so that excessive use of carbon taxes is avoided;...

Do Lower Prices For Polluting Goods Make Environmental Externalities Worse?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Brennan,   Timothy J.
Lower prices for polluting goods will increase their sales and the pollution that results from their production or use. Conventional intuition suggests that this relationship implies a greater need for environmental policy when prices of "dirty" goods fall. But the economic inefficiency resulting overproduction of polluting goods may fall, not rise, as the cost of producing those goods falls. While lower costs exacerbate overproduction, they also reduce the difference between private benefit and the total social cost--the sum of private and external costs--associated with that overproduction. We derive a test, based on readily observed or estimated parameters for conditions in which the latter effect outweighs the former. In such cases, making a dirty good...

The Costs and Benefits of Effluent Management Compliance in the Waikato Region of New Zealand
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gauntlett,   William.
Dairy farming in the Waikato Region has contributed greatly to the reduction of water quality. Part of this is attributable to the issue of inappropriate disposal of dairy effluent. Regional authority data shows both costs and benefits of complying with effluent management regulations. Private costs result from system and management improvements, while private benefits are largely due to reduced fertiliser requirements. Decreases in the volume of 'non-compliant effluent', resulting from improved compliance, are used as an indicator to illustrate reduced environmental effects. The benefits of becoming compliant outweigh the costs for half the farms analysed. More incentives are required to promote compliance from the other farms although their environmental...

This study examines media coverage of genetically modified (GM) crops in a risk communication framework. Content analysis is employed to investigate how specific environmental, food safety, and landmark events, such as the monarch butterfly and Pusztai controversies, and the cloning of Dolly-the-sheep, were reported by the media. Media coverage is from United Kingdom and United States newspapers over the period 1990 through 2001. On balance, findings show that the UK press has been more negative than the U.S. press in its coverage of GM crops.  In addition, environmental and food safety events had a significant impact on the level and cycle of GM crop coverage.

Effects of abolition of the EU milk quota system for Dutch agriculture and environment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Helming,   John F.M.; van Berkum,   Siemen.
Following model calculations presented in this paper he removal of the EU quota system will result in 21% more milk production in the Netherlands. Large dairy farms expand and achieve higher income levels compared to a scenario with quota continuation, as increasing scale of production and decrease of quota costs outweigh price reductions and extra manure disposal costs. Production in the category of relatively small farms, however, declines and farms in this category will leave business. Sector income will only marginally fall while production expansion will remain within the limits of present environmental policies related to manure and nutrient applications.

This paper develops a new measure of total factor productivity growth in agricultural production which incorporates environmental effects. The new measure is called the Total Factor Nutrient-Orientated Productivity (TFNP) Index, and incorporates a materials balance condition. TFNP measures changes in nutrient-orientated efficiency and can be decomposed into efficiency change (EC), technological change (TC) and nutrient-orientated technological change (NTC) components. An empirical analysis, involving country-level data from OECD countries during 1990-2003, is provided using DEA methods. Estimates of mean technical and nutrient-orientated efficiency are 0.798 and 0.526, respectively. Estimated mean TFNP growth is 1.5% per year, with nutrient-orientated...

Autores: Driml,   Sally; Clouston,   Beth; Bortman,   Amy.
The Queensland Government Environmental Offsets Policy provides an overarching framework for environmental offsets in Queensland. The policy provides a consistent and transparent approach to the use of offsets. It contains principles and guidelines for developing and applying more detailed ‘specific-issue’ policies for offsetting important environmental values such as vegetation or fish habitats. Currently, offsets use in Queensland can be characterised as a compliance mechanism as they are required to meet development conditions. Developers will face higher costs if they need an offset and this provides a greater incentive to avoid and minimise impacts on areas with significant environmental values.

Challenges and Issues in the Next Decade: A Proactive Role for Agricultural and Resource Economists
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Armbruster,   Walter J.
Economic and environmental challenges in the global economy raise significant issues that require public policy and private sector attention over the next decade. Price volatility, invasive species, sustainable biofuels production, and climate change all affect our agricultural and resource base and its future. Agricultural and resource economists must provide analyses of public policy and private sector strategies based on innovative research that integrates insights across disciplinary boundaries. Proactive communication of the results to decision makers can make a difference in how these important societal issues are addressed and help to shape the future.

THE TRADE AND ENVIRONMENTAL DEBATE: RELEVANT FOR SOUTHERN AGRICULTURE?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Marchant,   Mary A.; Ballenger,   Nicole.
This paper introduces and briefly discusses the economics of two important trade and environment policy issues--international harmonization of environmental standards and the use trade measures for environmental purposes.  Both issues are likely to generate lively international debate among environmentalists, industry representatives, and trade negotiators over the next few years.  As the international community seeks new multilateral rules in these areas, agricultural producers will want to know how they will be affected.  Thus, this paper also examines the potential impacts of environmental policy on the competitiveness of commodities unique to the Southern region of the United States.

FEEDLOT '99, PART I: BASELINE REFERENCE OF FEEDLOT MANAGEMENT PRACTICES, 1999
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS: Veterinary Services (VS). The NAHMS Feedlot '99 Study included feedlots of 1000-head or greater capacity from the 12 leading cattle feeding states. Feedlots included in the study represented 84.9 percent of U.S. feedlots of this size and contained 96.1 percent of the U.S. feedlot cattle inventory on feedlots with 1000-head or greater capacity as of January 1, 2000. For the purposes of the study, operations were grouped into two size categories: those with capacities of between 1000 and 7999 head, and those with capacities of 8000 head or more. Beef animals were the main type of cattle placed in feedlots regardless of operation size. Approximately one-half of the placements...

Framing for incentive compatibility in choice modelling
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mazur,   Kasia; Bennett,   Jeffrey W.
The incentives that motivate respondents to reveal their preferences truthfully have been a long-standing area of research in the non-market valuation literature. A number of studies have been undertaken to investigate incentive compatibility in nonmarket valuation. Most of these used laboratory environments rather than field surveys (e.g. Carson and Burton, 2008, Harrison, 2007, Lusk and Schroeder, 2004, Racevskis and Lupi, 2008). Only a few studies investigating incentive compatibility have considered multi-attribute public goods with an explicit provision rule in a choice experiment (Carson and Groves, 2007, Collins and Vossler, 2009, Carson and Burton, 2008). The design of a choice modelling study that avoids strategic behaviour has proven particularly...

Policy-Induced Technology Adoption: Evidence from the U.S. Lead Phasedown
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kerr,   Suzi; Newell,   Richard G.
The theory of environmental regulation suggests that economic instruments, such as taxes and tradable permits, create more effective technology adoption incentives than conventional regulatory standards. We explore this issue for an important industry undergoing technological responses to a dramatic decrease in allowed pollution levels - the petroleum industry's phasedown of lead in gasoline. Using a panel of refineries from 1971 to 1995, we provide some of the first direct evidence that alternative policies affect the pattern of adoption in expected ways. Importantly, we find that the tradable permit system used during the lead phasedown provided incentives for more efficient technology adoption decisions. Where environmentally appropriate, this suggests...

Scrap Tires in Ciudad Juarez and El Paso: Ranking the Risks
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen; Palma,   Alejandra.
According to conventional wisdom, rapidly growing stocks of scrap tires on the U.S.-Mexico border pose a variety of health and environmental risks. This article assesses these risks in Paso del Norte, the border's second-largest metropolis comprised principally of Ciudad Juarez, Chihuahua, and El Paso, Texas. We find that air pollution from tire pile fires poses the greatest threat. Scrap tires in Paso del Norte do not contribute significantly to the propagation of mosquito-borne diseases or to shortages of space in solid waste disposal sites. The burning of scrap tires at industrial facilities is minimal and might not have significant adverse environmental impacts even if it were more common.

Autores: Colyer,   Dale.
Paper presented at the 24th West Indies Agricultural Economics Conference, Granada, July 19-12, 2002.  Environmental issues have become important in trade agreement negotiations.  NAFTA explicitly includes environmental provisions and they are affecting ongoing WTO and FTAA negotiations.  The final role of the environment in the FTAA is uncertain, given opposition by most of the members.  The draft FTAA agreement does not contain a separate section on the environment, but a U.S. position paper indicates that environmental provisions are important and that U.S. negotiators will seek to incorporate environmental concerns into specific chapters such those on investment and agriculture.   The large number and varied economic and environmental conditions of the...

A dráguló olajár „felszínre hozta” a fosszilis energiahordozók környezetbarát energiahordozókkal való kiváltásának problémáját. Az olajkészletek korlátozottsága mellett a bizonytalan kitermelés és a folyamatosan növekvő árak a bioüzemanyagok felé irányítják a politikai döntéshozók és a befektetők figyelmét. Az olajimportőr országoknak a bioüzemanyag-gyártás nyersanyagainak hazai termelése lehetővé teszi importköltségeik visszafogását, az üvegházhatást okozó gázok kibocsátásának csökkentését, valamint a mezőgazdasági termelők jövedelem-színvonalának javítását. A bioüzemanyagok elterjedése ugyanakkor enyhíti a kapacitása határán dolgozó olajfinomító ipar üzemanyag-ellátási terheit is, ami jelentős mértékben hozzájárul(t) az üzemanyagárak emelkedéséhez.

Food QUALITY VERIFICATION: WHO DO CONSUMERS TRUST?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hobbs,   Jill E.; Innes,   Brian G.; Uzea,   Adrian D.
Food markets are increasingly characterized by an array of quality assurances with respect to credence attributes, many of which relate to agricultural production methods. A variety of organizations are associated with these quality assurance claims, including private, third party and public sector organizations. How do quality verifications from different sources affect consumer food choices? Who do consumers trust for assurances about credence attributes? This paper draws upon two recent studies to explore Canadian consumer attitudes toward environmental quality claims in a bread product and animal welfare quality claims in a pork product, along with attitudes toward quality verification from different sources. Analysis from two discrete choice...

Community Pressure and Clean Technology in the Informal Sector: An Econometric Analysis of the Adoption of Propane by Traditional Mexican Brickmakers
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen; Bannister,   Geoffrey J.
In many developing countries the informal sector, comprised of low-technology unlicensed micro-enterprises, is a major source of pollution. Environmental management in this sector is exceptionally challenging. Though clean technologies offer a means of mitigating the problem, to our knowledge there has been no rigorous empirical research on why informal (or even small-scale) firms do and do not adopt them. As a first step towards filling this gap, this paper presents the results of an econometric analysis of the diffusion of propane among informal 'traditional' brickmakers in Cd. Juárez, Mexico--a leading source of air pollution owing to their reliance on cheap, highly polluting fuels such as used tires and scrap wood. The two key policy implications of...

Police-powers, regulatory takings and the efficient compensation of domestic and foreign investors
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Aisbett,   Emma; Karp,   Larry S.; McAusland,   Carol.
In customary international and public law, “takings” resulting from regulations designed to protect the public good are generally excluded from compensation rules; this exclusion is known as a police powers carve-out (PPCO). Increasingly, this PPCO is being challenged, particularly in international investment law. This paper analyzes the efficiency properties of a PPCO in a model with endogenous regulation, investment and entry. We design a one-parameter family of carve-out/compensation schemes that induce efficient regulation and firm level investment even when the regulator suffers fiscal illusion and the social benefit from regulation is private information to the regulator. We show that offering a carve-out reduces the subsidy to risky industry...

Technologies for Meeting Future Global Demands for Food
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Crosson,   Pierre; Anderson,   Jock R.
Food can be produced under a number of technological conditions. Some observers hold that modern crop production technologies, typified by those embodied in the Green Revolution, are so intensive in the use of external inputs that they damage the environment and so are not sustainable. Those observers argue that "alternative" technologies that use fewer, safer external inputs mark the path toward agricultural sustainability. But the question arises: will those alternative technologies permit increases in global food production on the required scale? In this paper, we address this question and the conflicting arguments regarding the answer.

Forestry in the Next Millennium: Challenges and Opportunities for the USDA Forest Service
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Binkley,   Clark S.
Throughout the globe, forestry faces predictable trends associated with the transition from reliance on natural forests to ones created through human stewardship. Laid over the ordinary economics of this transition are increases in the values of the environmental services that forests provide. The three general approaches to forest management--natural forest management, plantation forest management, and preserve management--are evaluated in this economic context. The USDA Forest Service has interesting opportunities to apply each approach, but doing so will require profound organizational changes.

Autores: Chalak-Haghighi,   Morteza; Pannell,   David J.
Weeds can cause significant problems to natural ecosystems. Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. This paper addresses this gap in the literature by assessing the cost-effectiveness of a comprehensive range of control strategies for blackberry (Rubus anglocandicans) in natural environments in Australia. We developed a stochastic dynamic simulation model and a deterministic dynamic optimisation model. The stochastic model calculates the expected net present value (NPV) of a range of control strategies, including any combination of treatment options. The optimisation model identifies the treatment combination that maximises NPV. Both models represent the...

Effects of Environmental Regulation and Urban Encroachment on California’s Dairy Structure
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sneeringer,   Stacy E.
Environmental regulatory compliance costs are often cited as a factor in dairy location decisions, but few studies estimate the impacts of regulation in this sector. This article uses California dairy regulations to examine the pollution haven hypothesis in agriculture. Dairy industry regulation has varied regionally within the state, with the more strictly regulated Southern California region losing production and the more environmentally lenient Central Valley gaining production. Results show that even after controlling for population density and property values, regulation had significant negative effects on dairying in Southern California.

Welfare economics of conventional vs. alternative agriculture
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schamel,   Guenter.
We develop a agricultural model assuming that conventional production is causing environmental externalities while more benign alternative production methods generate non-market amenity benefits and obtain a price premium in the marketplace. We analyze policies targeting external benefits and costs to capture interaction effects: polluting input taxes reduce the returns and subsidies needed to induce more benign production. Thus, it is only optimal to subsidize if the additional marginal amenity benefit exceeds the marginal external cost reductions due to the input tax. Terms of trade effects imply that large (land abundant) exporters have strategic incentives to overvalue external costs while large (land scarce) importers have strategic incentives to...

Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction.  Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products.  Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk.  Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM.

Autores: Hipp,   Janie S.; Francis,   Harriet F.
Agriculture has seen a steady movement toward the increased use of contracts.  Agricultural contracts now guide the interrelationships of parties throughout the modern production system, extending well beyond the livestock sector.  With this predominance come new issues that require us to reexamine contract theory and the roles of the parties.  This review examines legislation, regulations, and recent court rulings in seemingly unrelated areas that have specific relationships to the development of contracts in production agriculture: environmental law and labor law.

We seek to contribute to the emerging economic theory on trade, the environment and development. Using panel data across countries, econometric models are estimated to predict the effects of openness on organic water pollutant (BOD) and carbon dioxide (CO2) emissions. Results indicate that freer trade significantly increases emissions of both pollutants, thus reducing environmental quality. Moreover, the panel nature of the data allows heterogeneity across countries to be controlled, so that comparisons can be made of how different national characteristics influence the environmental impact of freer trade. By testing the effects of democratic versus autocratic governance, it is found that while greater democracy can induce significant reductions in BOD...

Obstacles to a Doubly Green Revolution
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen.
Increasingly, conventional wisdom dictates that agrarian policy in developing countries should foster a "doubly green revolution" that both protects the environment and boosts output. Like the first green revolution, such a transformation will entail convincing millions of farmers to adopt new practices and, as a result, will confront well-documented barriers to technological change in developing-country agriculture. It will also face a number of new obstacles, including a divergence between the interests of policymakers and farmers, a policy environment biased in favor of input-intensive agriculture, and the fact that many environmentally friendly technologies entail relatively high set-up costs. At least in the short run, institutional constraints will...

Panel data from 241 farm households were collected three times over a period of four years in five rice-producing provinces of Thailand. Data included socio-economic data describing household and farm characteristics, rice input and output data including detailed accounts of pesticide use and other pest management practices and farmers' knowledge of crop management and agro ecosystem factors. Using the concept of environmental impact quotient parameters on the health and environmental consequences of a change in pesticide use was computed.  Data analysis was...

Social Opportunities and Private Convenience of Choices at Farm Level: An Approach to the Links Between Farm Income and Sustainable GDP
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Idda,   Lorenzo; Sini,   Maria Paola.
This work proposes a method to identify and evaluate the links between the economic and environmental management of a farm, its income, and sustainable GDP. The approach is designed to link micro and macro economic aspects and is based on certain indicators, chosen from among those obtained from analysis of the farm accounts, suitable for representing socially desirable objectives. Three different types of farm accounts are employed. An MADM method of quantitative MCDM analysis was used to make a joint evaluation of various objective indicators in different types of farm management. The work only presents the most interesting result of the research, which was the method itself and does not include the results of a specific case study which was made. This...

SOCIETAL PERCEPTIONS OF AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wachenheim,   Cheryl J.; Rathge,   Richard W.
Tension between farm operators and their surrounding neighbors within rural communities continues to escalate as residents become increasingly removed from production agriculture.  An expanding gap exists between public perceptions of the effects of the structure and production  practices of modern agriculture, and reality.  Combined with a shrinking farm population and support base, misperceptions may have important consequences for farm legislation and regulations.  Obtaining knowledge about how the public views agriculture is a necessary step in correcting misperceptions and may help the industry and policy makers understand  the beliefs and values of the populace.  Collecting information about perceptions of agriculture among residents of the North...

Unprotected Resources and Voracious World Markets
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Margolis,   Michael; Shogren,   Jason F.
The Theory of the Second Best implies that any country with less-than-ideal resources can lose from international trade. Recently it has been suggested this means the South (poor countries) are better off suppressing trade with the North, especially trade in natural resource products, since the North has better developed rights to protect its natural resources. Here we show that the suppression of such trade may also impede the development of property rights in the South, but that even taking this into account, trade liberalization need not improve Southern welfare. We find that within a cone of world prices on the boundary of which lies the South's autarky price vector, welfare losses still occur even when local governments in the South make optimal...

Manure Application Rules and Environmental Considerations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Massey,   Raymond E.; Gedikoglu,   Haluk.
Three manure application limits (N Limit, Annual P Limit and P Banking) were modeled with particular attention to the number of hours needed to appropriately distribute manure.  The benefit and costs estimates indicated that P Banking was more profitable than N Limit which was more profitable than Annual P Limit.  The number of hours required indicated that the Annual P Limit would not be completed within a two month window approximately 2 of 10 years.  The increased number of hours for the Annual P Limit also increased the probability of a runoff event following manure application, relative to the other two scenarios.  This work indicates that regulations that require Annual P Limits of manure cost the farmer and may have the unintended consequence of...

Environmental Policy, Education and Growth with Finite Lifetime: the Role of Abatement Technology
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pautrel,   Xavier.
This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and lifetime is finite. When the human capital’s share in the abatement services production is higher (respectively lower) than in the final output production, a higher environmental tax reduces (resp. increases) the allocation of human capital in production sectors (abatement service and final output) and boostes (resp. decreases) the BGP rate of growth. When abatement services are produced with the final output, the environmental taxation does not influence growth.

Mathematical programming models suit policy makers' needs for assessing impacts of new policies and modellers' needs for new parameters, constraints and activities to represent the phenomenon under study. The AROPAj model aims at taking into account any geographical extension of the European Union as well as the continuously changing Common Agricultural Policy. As well as the European policies will include more and more environmental problems, AROPAj will be more and more designed toward environmental assessments. Two improvement axes are set up. Biophysical models are used to refine the design of farming systems represented in the economic model and to estimate nitrogen pollutant emissions. Down-scaling methods are coupled with the regional farm group...

Like Products, Health and Environmental Exceptions: The Interpretation of PPMs in Recent WTO Trade Dispute Cases
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Read,   Robert.
This article is concerned with the ongoing debate on process and production methods (PPMs) and the extent to which existing GATT 1994 articles and WTO agreements are able to deal with these issues. The article provides an overview of GATT articles III.4 on like products and XX on general exceptions as well as the SPS and TBT agreements. It then summarises four recent GATT/WTO trade dispute cases involving PPM issues: tuna-dolphin; shrimp-turtle; gasoline standards; and asbestos. The WTO panel and appellate body decisions in these cases are analysed with regard to articles III.4 and XX in the context of the evolution of WTO case law with respect to PPMs. Inferences are also drawn concerning the likely implications for a potential trade dispute over GM...

Agriculture, Environmental Services and Agro-Tourism in the Dominican Republic
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Catalino,   Alejandro Herrera; Lizardo,   Magdalena.
This paper analyzes the links between agriculture and tourism. A contingent valuation study assesses tourist's willingness to pay (WTP) for agro-tourism and agriculture's positive environmental services and related positive externalities. The paper analyzes factors influencing tourist preferences in the Dominican Republic (DR) -- tourist income, the local tourist destination, sex, and nationality stand out among these factors. Estimates are given for different WTP scenarios according to farming systems. The study argues that a well developed agro-tourism industry would result in a market mechanism generating additional income of US $251 to US $364 million annually. Agro-tourist activities would have the added benefit of promoting sustainable agricultural...

The Effects of a Provision Rule in Choice Modelling
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mazur,   Kasia; Bennett,   Jeffrey W.
This research report investigates the effects of including a provision rule in choice modelling non-market valuation studies. Split samples with and without a provision rule were used to test for differences in household willingness-to-pay for improvements in environmental quality in the Hawkesbury-Nepean catchment. Local/rural and distant/urban sub-samples of residents were selected.   The results of the study show that the inclusion of a provision rule had an effect on preferences in the distant/urban communities; however, the impact of a provision rule in the local/rural community sub-samples was negligible.

Environment protection: challenges for future farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pannell,   David J.
There has been increased public demand for environment protection, including in rural areas. Government programs and policies have responded to these demands in various ways, such as by attempting to increase farmer awareness of environmental issues, increasing budgets for rural environmental programs, increasing environmental regulation, purchasing water from irrigators for environmental purposes, and encouraging farmer adoption of new environmentally friendly practices. These changes create a number of challenges for farmers, including challenges related to maintaining farm productivity, meeting community expectations, living with less water and evaluating new opportunities. These challenges are described and discussed. While there certainly are...

Autores: Bewsell,   Denise; Kaine,   Geoff.
The adoption of environmental management practices is addressed in this paper. The use of consumer behaviour theory and a market research approach is discussed by describing how it was used in the study. Qualitative methods were used to gather data from dairy farmers in four New Zealand catchments. The environmental practices explored were; excluding stock from waterways, reducing phosphorus use, improving soil macroporosity, managing effluent and improving the efficiency of border-dyke irrigation. The findings are discussed, highlighting that farm contextual factors influenced farmers’ decision making in terms of adopting environmental management practices. The results suggest that environmental practices need to be linked to farm context. This should...

Health-enhancing Activities and the Environment: How Competition for Resources makes the Environmental Policy Beneficial
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pautrel,   Xavier.
In a two-period overlapping generations model, this paper demonstrates that the relationship between the environmental taxation and the economic activity (level- and growth-output) becomes inverted-U shaped, when the detrimental impact of pollution on health and the private decision of each working-age agent to improve her health are taken into account. Especially, a tighter environmental tax is more likely to promote (rather than to harm) output-level and –growth when health is very sensitive to pollution, the weight of health in preferences is high, the polluting capacity of the production technology is high and the rate of natural purification of pollutants is low. The inverted-U shaped relationship between the environmental tax and the economic...

Pollution, Health and Life Expectancy: How Environmental Policy Can Promote Growth
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

This article investigates the influence of environmental policy on growth assuming that the channel of transmission relies on the link between pollution, health and the survival probability, in an overlapping generations model à la Blanchard (1985) where growth is driven by a mechanism à la Romer (1986). We demonstrate that environmental policy has an ambiguous effect on growth in the steady-state when the detrimental impact of pollution on health and lifetime is taken into account: for low levels of taxation, environmental policy promotes growth while it is harmful to growth for high levels. Furthermore, we show that the environmental policy is more likely to promote growth (i.e. it stimulates growth for a wider range of environmental taxes) when public...

Commodity payments in Europe and North America are production based, encouraging greater chemical use and cropping area. Thus, each region undermines the other’s price supports at the expense of the environment. Countries can, however, sever the link between yield levels and payments. Allowing farmers to exit agriculture poses challenges for the US, but perhaps not for Canada and the EU.

Global climate changes are taking place and its impacts on economy are already occurring in fields like tourism, agriculture, forestry, infrastructure, insurance industry or capital market. Specialists draw attention that climate change has negative effects and positive effects. For example, in some parts of Europe, especially in north, the agricultural may benefit from temperature rise increasing carbon dioxide levels in the atmosphere. The most important part of these changes is due to greenhouse gas (GHG) emissions from human activity. Between greenhouse gases, carbon dioxide (CO2) is the largest contributor with a weight around of 80% of total GHG emissions. The agriculture is the most affected sector by the climate change, but agricultural activities...

Muddling Through while Environmental Regulatory Capacity Evolves: What Role for Voluntary Agreements?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Blackman,   Allen; Sisto,   Nicholas.
The city of Leon, Guanajuato, is Mexico's leather goods capital and a notorious environmental hotspot. Over the past two decades, four high-profile voluntary agreements aimed at controlling pollution from Leon's tanneries have yielded few concrete results. To understand why, this paper reconstructs the history of these initiatives, along with that of local environmental regulatory capacity. Juxtaposing these two timelines suggests that the voluntary pollution control agreements were both motivated by-and undermined by-gaps in the legal, institutional, physical, and civic infrastructures needed to make regulation effective. Our analysis offers a concrete definition of environmental regulatory capacity, provides insights into how it evolves, and demonstrates...

The Effects of Environmental Regulation On Technology Diffusion: The Case of Chlorine Manufacturing
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Snyder,   Lori D.; Miller,   Nolan; Stavins,   Robert N.
We use a hazard model to estimate the effect of environmental regulation on the diffusion of membrane cell production technology in the chlorine manufacturing industry. We estimate the effect of regulation on both the adoption of the membrane technology at existing plants and on the exit of existing plants using older technologies. We find that environmental regulation did affect the diffusion of the cleaner technology in the chlorine industry. However, it did so not by encouraging the adoption of membrane cells by existing facilities, but by reducing the demand for chlorine and hence encouraging the shutdown of facilities using the environmentally inferior options.

This paper discusses the findings from a pilot study of New Zealand agricultural consultants aiming to describe the role of agricultural consultancy within the New Zealand RD&amp;E system with specific reference to their role in environmental management. The study comprised a literature review, interviews with informed persons and case studies. Agricultural consultants generally operate chiefly in the area of farm economics and management, but their positioning makes them well-placed for impacting positively on environmental management on farms. They assist producer decision-making by providing industry intelligence, up-to-date information and analysis of options.

With complementary Chinese data sets and alternative corruption measures, we explore the consequences of corruption. Adopting a novel approach we provide evidence that corruption can have both, positive and negative effects, on economic development. The overall impact of corruption might be the balance of the two simultaneous effects within a specific institutional environment (“grease the wheels” and “sand the wheels”). Corruption is observed to considerably increase income inequality in China. We also find that corruption strongly reduces tax revenue. Looking at things from an expenditure point of view we observe that corruption significantly decreases government spending on education, R&amp;D and public health in China. We also observe that regional...

Risky Activities and Strict Liability Rules: Delegating Safety
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mondello,   Gerard.
This paper studies the delegation of activities that pose serious risks to health and the environment in an economy regulated by strict liability schemes. Strict liability induces judgment-proof possibilities. Two civil liability regimes are then compared: a strict liability scheme and a capped strict liability one. The argument is led under a twofold asymmetric information assumption between the principal and the agent: the efficiency level in effort for safety and the agent’s level of wealth. The paper shows that standard strict liability under information asymmetries deters the efficient agent to compete and favors adverse selection. Then, under conditions, a capped strict liability regime is a better regime than a standard strict liability one because...

Abatement Technology and the Environment-Growth Nexus with Education
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pautrel,   Xavier.
This article challenges the conventional result that a tighter environmental tax has no long-run effect on human capital accumulation in the presence of pollution arising from final output production. It demonstrates that the technology used in the abatement sector determines the existence and the direction of the growth-effect. A tighter environmental tax rises (respectively reduces) human capital accumulation in the presence of pollution arising from final production, if the abatement sector is relatively more intensive in human (resp. physical) capital than final sector. That result always holds for finite lifetime but for infinite lifetime it only holds when labor supply is endogenous. The transitional impact of a tighter environmental policy is also...

On the Economics of Precision Agriculture: Technical, Informational and Environmental Aspects
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anvec,   Tihomir; Whelan,   Brett; McBratney,   Alex.
The paper presents an integrated framework of biophysical and economic modelling as a novel approach towards precision agriculture research. A theoretical economic model determining the optimal number of precision agriculture management units within a given field of land is presented. The model is expanded to account for the value of the research information provided be the precision agriculture researchers. Since the inherent environmental values associated with precision agriculture are often omitted from the economic analysis, an attempt is made to incorporate these values into the model. The versions of the model are empirically tested using the data available.

Diagnosis and evaluation of fungi presence in the air of two different ventilation sytems for broiler houses
Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Gigli,ACS; Baracho,MS; Nääs,IA; Silva,RA; Zago,R; Dall'Anese,FP.
Intensive broiler production in tropical climates requires adequate air circulation to control heat stress. Excess of air speed may lead to dust production and reduction of air quality and, consequently, production parameters. Brazilian regulations prohibit the presence of pathogens that may deteriorate air quality, and the presence of fungi in the air inside the poultry houses is limited to 750CFU/m³. The aim of this study was to evaluate the presence of fungi in two distinct types of broiler houses. The research compared two types of air ventilation: conventional (G1) and positive tunnel ventilation (G2). The fungi were collected using a dust sampling pump, with the air flow calibrated to 1.5 L/min. The filter impregnated with dust was submitted to...

Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Queiroz,ML de V; Barbosa Filho,JAD; Duarte,LM; Brasil,D de F; Gadelha,CRF.
The objective of this study was to determine the critical points of the operation of broiler catching for transport to the processing plant from animal and operational perspectives. During catching, chickens, environmental variables (temperature and relative humidity) were constantly monitored to determine the Enthalpy Comfort Index (IEC). Also, the physiological variable rectal temperature (RT) was monitored as an indicator of stress suffered by the birds during this handling procedure. Bird welfare were evaluated by analyzing their behavior. The bag method was effective to prevent the struggling of birds while being taken from the broiler house to the transport truck, reducing physical injuries and losses during catching.

Egg quality in layers housed in different production systems and submitted to two environmental conditions
Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Barbosa Filho,JAD; Silva,MAN; Silva,IJO; Coelho,AAD.
The production system using cages is a highly polemical issue in Europe, because of the space restriction imposed to laying hens. It is considered that the cage system might compromise important comfort movements, welfare and egg quality. This study evaluated egg quality and welfare of two strains of hens housed in a conventional system (battery laying cages) or litter system with nest and perches, and submitted to heat stress or comfort conditions. Two groups of 20 birds (10 Hy-line W36 and 10 Hy-line Brown) were submitted to two environmental conditions (26°C and 60% RH or 35°C and 70% RH) and two housing systems (cages or litter) in the early production phase. Egg quality was analyzed based on egg weight, eggshell thickness, specific gravity, and Haugh...

Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Ferreira,Alexandre C. de B.; Bogiani,Julio C.; Sofiatti,Valdinei; Silva Filho,João L. da.
ABSTRACT Cotton stalk regrowth must be controlled after harvest to ensure the phytosanitary quality and sustainability of cotton farming systems. Mechanical destruction generally does not conform to the no-tillage system, and the control of cotton stalk regrowth by herbicides is little studied in Brazil. The objective of this study was to evaluate the efficiency of herbicides to control glyphosate-resistant transgenic cotton stalk regrowth. The study was conducted in three environments of the Brazilian Cerrado region, two in Santa Helena de Goiás (SHGO), during 2013 and 2014, and one in Luís Eduardo Magalhães (LEM-BA) in 2014. In each of the three environments, the experiment was carried out in a randomized complete block with four replications. Each...

Autores: Monteiro,Divanildo Outor; Pinheiro,Victor Manuel Carvalho; Mourão,José Luís Medeiros; Rodrigues,Miguel António Machado.
This work presents strategies that can be implemented in order to minimize the environmental impact of swine slurry on soil, water, and air. This reduction can be achieved through decrease in nitrogen excretion and ammonia emissions. The correct feed formulation according to animal requirements, the increase in diet digestibility and improvement in animal performance can reduce nitrogen excretion. The use of additives either in the diet or in the manure as well as some equipment rearrangements can reduce ammonia emission.

What mineral and vitamin levels to recommend in swine diets?
Provedor de dados: Revista Brasileira de Zootecnia
Autores: Gaudré,Didier; Quiniou,Nathalie.
Minerals, including trace-elements, and vitamins are currently introduced into the pig diet in order to obtain suitable performances for the modern pig genotype bred in confinement. Most of the mineral and vitamin contents of cereals and usual protein compounds are characterized by their poor and variable availability. Supplemental diets are then usually needed. This paper, based on literature data, reviews the pig requirement for minerals and vitamins in order to ensure economic and profitable performance. Recent research has focused on phosphorus due to environmental considerations. The widespread use of microbial phytase has decreased the need for inorganic phosphates.

Autores: Leite,Daniela Dantas de Farias; Queiroz,Alexandre José de Melo; Figueirêdo,Rossana Maria Feitosa de; Lima,Leiliane Silva Lopes.
ABSTRACT Jackfruit (Artocarpus heterophyllus Lam.) is a fruit with pulp rich in carbohydrates, calcium, phosphorus, iron and B-complex vitamins. A large amount of waste is generated in the pulp processing, in which the seeds are included. Jackfruit seeds are often consumed after cooking, and may also undergo roasting, milling and incorporation into bakery products. The remaining jackfruit seeds can be germinated as a means to increase its utilization, constituting a process that confers positive biochemical modifications to the nutritional quality. Thus, the objective of this work was to dry the germinated seeds of the jackfruit tree in a convective drier at 55, 65 and 75 °C with drying air velocities of 1.0 and 1.3 m s-1, and adjusting different...

The economic and environmental impact of trade in forest reserve obligations: a simulation analysis of options for dealing with habitat heterogeneity
Provedor de dados: Revista de Economia e Sociologia Rural
Autores: Chomitz,Kenneth M.; Thomas,Timothy S.; Brandão,Antônio Salazar P.
A tradeable development rights (TDR) program focusing on biodiversity conservation faces a crucial problem: defining which areas of habitat should be considered equivalent. Restricting the trading scope to a narrow area could boost the range of biodiversity conserved but could increase the opportunity cost of conservation. The issue is relevant to Brazil, where TDR-like policies are emerging. Long-standing laws require each rural property to maintain a legal forest reserve (reserva legal) of at least 20%, but emerging policies allow some tradeability of this obligation. This paper uses a simple, spatially explicit model to simulate a hypothetical state-level program. We find that wider trading scopes drastically reduce landholder costs of complying with...

Provedor de dados: Scientia Agricola
Autores: Montardo,Daniel Portella; Dall'Agnol,Miguel; Paim,Nilton Rodrigues.
Red clover (Trifolium pratense L.) is one of the most important temperate legume species, used to lessen the lack of forage during the critical fall-winter period in Rio Grande do Sul, RS, Brazil. However, its utilization has been restricted mainly because of its lack of persistence. This work evaluates the dry matter yield and persistence of red clover half-sib progenies in two physiographic regions of RS: "Depressão Central", in Eldorado do Sul and "Encosta Superior do Nordeste", in Veranópolis. Experiments were carried out for two growing seasons and results were compared to two red clover commercial checks, Qüiñequeli and Estanzuela 116. The region of Veranópolis was more adequate for red clover forage production, enabling better yield and persistence....

Provedor de dados: Scientia Agricola
Autores: Leal Filho,Walter.
The on-going economic development of EU-countries as well of the countries in the C&amp;E European region has been leading to a significant use of a great deal of natural resources as well as to noticeable environmental problems. The lack of a wide-spread environmental awareness from the side of those acting in various sectors (industry, public administration, users) sometimes inhibit the implementation of legislation already available as well as the introduction of new technologies deriving, from example, from marine research. An example of this state of affairs is seen in respect of the implementation of the recommendations deriving from Baltic 21 and VASAB 2010, which illustrate the advantages from a cross-sectorial, open mechanism for the dissemination...

Abstract The jelly palm plant [Butia capitata (Martius) Beccari] is a native palm of the Cerrado biome used for many purposes in northern Minas Gerais State, Brazil. Dormancy is common in palm seeds, resulting in slow and uneven germination that may take years to complete. Modification in the growth pattern, anatomical parameters, physiological and biochemical characteristics of the plant can be verified due to changes in the light spectrum transmitted through colored shade nets used. Therefore, the objective of this study is to evaluate the effect of colored shade nets on the leaf and root anatomy of the jelly palm plant. The experiment was performed in a completely randomized design, with five treatments, ten replicates and eight plants per replicate,...

Sporothrix schenckii in a hospital and home environment in the city of Pelotas/RS - Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Mattei,Antonella S.; Madrid,Isabel M.; Santin,Rosema; Silva,Franklin V.; Carapeto,Luiz P.; Meireles,Mário C.A.
This study describes the isolation of S. schenckii in hospital and home environments in Brazil. Samples were collected from surfaces of a veterinary service place and at home. S. schenckii was detected in 1.5% of the samples from the hospital environment. However, this fungus was isolated from all sampled areas in home environments. The isolation of S. schenckii deonstrates that these surfaces could act as infection sources to anials and huans. Therefore, employees and pet owners could be exposed to this agent, and the contamination, through surfaces, could occur through the traumatic inoculation of the fungus or by direct contact with pre-existing lesions.

Converting a Conventional Vehicle into an Electric Vehicle (EV)
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Silva,Jardel Eugenio da; Urbanetz Junior,Jair.
Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their price, electric cars were forgotten. Only almost a century later, they returned in the market due to a significant increase in fossil fuels prices, as well as to a growing environmental concern. EVs present a number of advantages over ICE vehicles: they are simpler and require less use and replacement of parts, resulting in lower maintenance costs; moreover, they do not release pollutants into the...

Wool production and reproductive performance components of similar genotypes, brought from distinct production areas, were evaluated during five years trial at similar environments, such as, joining season and stocking rate on winter improved pasture. The least squares means revealed that the origin (breed) effect concentrated upon the Corriedale ewes wool production, whereas in Romney females it affected the reproductive performance. In the abscence of interaction between origin (breed) and year for most variables, it was assumed that the farm management procedures and/or selection criteria applied on hoggets were determinant of the subsequent lifetime production within each genotype examined. Expecting a better reproductive performance in Romneys, mainly...

Wastes from the seafood industry can be easily processed into products with new forms of use. The present study was aimed at determining the chemical composition and functional properties of shrimp waste protein concentrate and lyophilized flour. The raw material used in this study consisted of waste (head) of Litopenaeus vannamei. The protein concentrate was obtained by ethanolic extraction, being subsequently submitted to drying in oven at 70° C, while the flour was obtained by lyophilization of shrimp wastes. Moisture, ash, protein and calcium contents showed significant difference between fresh shrimp head waste samples (IN) and protein concentrate and lyophilized flour samples. The protein content for protein concentrate (PC) and lyophilized flour...

The objective of this study was to evaluate the effect of reduced-crude protein (CP) and available phosphorus (aP) diets, added with phytase and amino acids for broilers in the growing (14 to 21 days old) and retirement (35 to 42 days) phases on nitrogen, potassium and phosphorus balance. Ninety Cobb broilers were distributed in a completely randomized design with three treatments and six replications with five and three birds per experimental unit in the growing and retirement phases, respectively. Diets were elaborated to contain reduced CP and aP levels (19 and 17% CP in the growing phase, with 0.34% aP; and 18 and 16% CP in the retirement phase, with 0.30% aP), supplemented with crystalline amino acids and 500 FTU of phytase/kg diet. These were...
