This article addresses the question, to what extent and under which conditions nontimber forest product (NTFP) trade leads to both livelihood improvement and forest conservation. We based the analysis on a standardized expert-judgment assessment of the livelihood and environmental outcomes of 55 cases of NTFP trade from Asia, Africa, and Latin America. The results show that NTFP trade benefits several components of peoples' livelihoods, but may increase inequality between households. Involvement of women in the production-to-consumption system (PCS) tends to have a positive impact on intrahousehold equity. In 80% of the cases, the commercial production of NTFPs does not enable people to make financial investments to increase quality and quantity of...

The Northern Highlands Lake District of Wisconsin is in transition from a sparsely settled region to a more densely populated one. Expected changes offer benefits to northern Wisconsin residents but also threaten to degrade the ecological services they rely on. Because the future of this region is uncertain, it is difficult to make decisions that will avoid potential risks and take advantage of potential opportunities. We adopt a scenario planning approach to cope with this problem of prediction. We use an ecological assessment framework developed by the Millennium Ecosystem Assessment to determine key social and ecological driving forces in the Northern Highlands Lake District. From these, we describe three alternative scenarios to the year 2025 in which...

The data requirements for most quantitative fishery assessment models are extensive, and most of the fisheries in the world lack time series of the required biological and socioeconomic data. Many innovative approaches have been developed to improve data collection for fisheries. We explored the use of data from fishers&amp;#8217; interviews to estimate time series of approximate &amp;#8220;best&amp;#8221; catch rates. A total of 472 standardized interviews were conducted with 423 fishers along the southern Red Sea coast recording the best catch recalled and the change in average catch rates throughout the fishing career of interviewees. The results showed a decline of best catch rates in all fisheries, ranging from 4% to 10% per year for more than 50...

Assessments of ecosystem services have been proposed as one way of incorporating concerns about environmental change and ecosystem conditions into subnational development planning.  In Thailand a policy window for such initiatives is opening because of a transition in national policy toward area-based planning combined with broader political reforms to expand public participation and encourage more evidence-based decision making. We explored three case studies in Thailand in which central and local government agencies and research organizations partnered to engage local communities and other stakeholders in assessments of ecosystem services and human well-being.  The analysis focused on the role ecosystem assessments play in building and creating demand...

Analysis of gear interactions in a hake fishery: The case of the Gulf of Lions (NW Mediterranean)
Provedor de dados: 5
Autores: Aldebert, Yvonne; Recasens, Laura; Lleonart, Jordi.
The hake of the Gulf of Lions is the most important target species of the demersal fishery. It is exploited by four types of gear (two trawls, gillnet and longline) used by two countries (France and Spain). Some analyses of its dynamics, based on 19 88 length frequency data by gear, have been performed. These analyses consisted in a VPA (Virtual Population Analysis). phis a Y/R (Yield per Recruit analysis) carried out on two parameter scenarios by sex, under a steady state hypothesis (with constant recruitment). Some estimates of biomass and exploitation level were obtained, and sensitivity to the biological parameters and interaction between types of gear were studied. As a main conclusion, it can be seen that the types of gear fishing mainly small...

Provedor de dados: 5
Autores: Vigneau, Joel; Fifas, Spyros; Foucher, Eric.
The methodology used for obtaining absolute abundance indices for Eastern Channel scallop is described in this paper. For the survey (COMOR), stratified multi-stage random sampling is used. The number of sampled units is computed based on variance estimates from the last survey. Knowledge of gear (Brittany dredge with a diving plate) selectivity and efficiency parameters is required for estimating total exploitable biomass and absolute abundance indices by age and strata. Details of the mathematical development of all estimators are given. A non parametric bootstrap provides confidence intervals for all estimates.

A triage approach to improve the relevance of marine ecosystem services assessments
Provedor de dados: 5
Autores: Pendleton, Linwood; Mongruel, Remi; Beaumont, Nicola; Hooper, Tara; Charles, Mahe.
Ecosystem services assessments are increasingly being used to inform marine policy and planning. These assessments involve significant time, effort, and expertise. It is important at the outset to determine which of many ecosystem services should be quantified and which measures of ecological output, economic impact, or value should be assessed. Furthermore, the literature shows that in practice such assessments are unevenly applied and rarely used effectively in decision-making processes. We develop a structured decision-making approach, called a triage, to assess what types of ecosystem services should be assessed to improve the uptake and usefulness of such information in marine planning. Two case studies, in France and the United Kingdom, provide...

Autores: Devreker, David; Lefebvre, Alain.
This report is the second assessment of French marine water eutrophication status (descriptor 5) done in the framework of the MSFD. The goal of this report is to determine if French marine water reach the Good Ecological State as defined by the MSFD. It stands next to the initial evaluation made in 2012, from which it is an update. It introduces the second cycle of the Marine Environment Action Program. It shows that French marine waters, behind the 12 nm line, reach the GES as defined by the MSFD. Problems link to eutrophication occurs in marine waters above the 12 nm, where 6.5% of the area do not reach the GES.

Autores: Hylland, Ketil; Robinson, Craig D.; Burgeot, Thierry; Martinez-gomez, Concepcion; Lang, Thomas; Svavarsson, Jorundur; Thain, John E.; Vethaak, A. Dick; Gubbins, Mattew J.
This paper reports a full assessment of results from ICON, an international workshop on marine integrated contaminant monitoring, encompassing different matrices (sediment, fish, mussels, gastropods), areas (Iceland, North Sea, Baltic, Wadden Sea, Seine estuary and the western Mediterranean) and endpoints (chemical analyses, biological effects).  ICON has demonstrated the use of a framework for integrated contaminant assessment on European coastal and offshore areas. The assessment showed that chemical contamination did not always correspond with biological effects, indicating that both are required. The framework can be used to develop assessments for EU directives. If a 95% target were to be used as a regional indicator of MSFD GES, Iceland and offshore...

Radar altimeters have been measuring ocean significant wave height for more than three decades, with their data used to record the severity of storms, the mixing of surface waters and the potential threats to offshore structures and low-lying land, and to improve operational wave forecasting. Understanding climate change and long-term planning for enhanced storm and flooding hazards are imposing more stringent requirements on the robustness, precision, and accuracy of the estimates than have hitherto been needed. Taking advantage of novel retracking algorithms, particularly developed for the coastal zone, the present work aims at establishing an objective baseline processing chain for wave height retrieval that can be adapted to all satellite missions. In...

Scenario analyses have been used in multiple science-policy assessments to better understand complex plausible futures. Scenario archetype approaches are based on the fact that many future scenarios have similar underlying storylines, assumptions, and trends in drivers of change, which allows for grouping of scenarios into typologies, or archetypes, facilitating comparisons between a large range of studies. The use of scenario archetypes in environmental assessments foregrounds important policy questions and can be used to codesign interventions tackling future sustainability issues. Recently, scenario archetypes were used in four regional assessments and one ongoing global assessment within the Intergovernmental Science-Policy Platform for Biodiversity...

Coastal areas are complex socio-ecosystem where ecological, human and decisional compounds show multiple and reciprocal relationships. Because of the growth of population and tourism sector, coastal areas are permanently threatened through increase of recreational uses and diversification of related activities. To better understand coastal areas functioning, it is necessary to take into account uses and their management. Monitoring data over a ten years period revealed that recreational uses greatly increased especially within Marine Protecting Areas (MPA), during week-end days and warm season resulting to higher and more frequent frequentation peaks. While, practices within MPA are managed to decrease impacts, pressures associated with recreational uses...

Intersection-union tests for characterising recent changes in smoothed indicator time series
Provedor de dados: 5
Autores: Trenkel, Verena; Rochet, Marie-joelle.
Using indicator time series for assessment and management requires methods for characterising recent time trends. We propose an approach where first the indicator time series is smoothed using a generalised additive model with optimal selection of the degree of smoothness. Second an intersection-union test is carried out using two test statistics which are the occurrence of the global maximum (or minimum) within the most recent years and the signs of the estimated annual first derivatives of the smoothed indicator times series during the same period, including years with missing data. The proposed test is applied to fish abundance indices for the North Sea, for which it is they are able to pick up changes happening during the last 3-5 years in contrast to...

Evidence of a variable "unsampled" pelagic fish biomass in shallow water (&lt; 20 m): the case of the Gulf of Lion
Provedor de dados: 5
Autores: Brehmer, P; Guillard, J; Guennegan, Yvon; Bigot, Jean-louis; Liorzou, Bernard.
Studies of small pelagic fish biomass are limited by the fact that research vessels and fishing boats are usually restricted to working areas with a bottom depth &gt; 20 m. Consequently, "unsampled" areas can represent a large proportion of the continental shelf, and the biomass in those areas can be important and must be taken into account in assessment methods in order to avoid misleading interpretations in population dynamics. A time-series tell years long has been compiled from acoustic-assessment surveys of small pelagic fish stocks, and the results show an overall increase in the acoustic fish density towards the coast, where values were the highest. Additional experiments on transects covering shallow-water areas (5-20 m) were conducted from 2001 to...

This paper develops a critical overview of the various problems and uncertainties faced in tuna stock assessment, management and conservation. This presentation is based on Atlantic tunas, but also on various tuna stocks worldwide. Tuna jisheries management is characterized by major uncertainties in the stock assessment; since these stock assessments are always done only on jishery data which are often biased. Fortunately most tuna stocks are showing a strong resistance to overfishing. These major characteristics of tuna stocks and jisheries, and the bias in the scientific analysis, are presented and discussed. As a result, many of the reference point recommended for the precautionary approach applied to jisheries are often quite inappropriate for tuna...

Sardine series in PELGAS surveys : PELGAS 2000 to 2005
Provedor de dados: 5
Autores: Masse, Jacques; Duhamel, Erwan; Delaunay, Damien.
Survey data from 2000 to 2004 were used to analyse whether sardine show a preferential distribution in relation to bottom depth and/or latitude. For this analysis, four strata were considered; North or South of latitude 46°N (separating VIIIa and VIIIb) and bottom depths deeper or shallower than 110m. Sardine length distributions are plotted as the proportion of small (&lt; 18.5 cm) or big (larger than 18.5 cm) fish on the samples over the years. This division was chosen to take into account the bimodal structure of sardine length distributions (usually with a "valley" at 18.5 cm fish length). Small fish (mainly 1 year old) are generally found close to the coast and preferentially in the southern part. The year 2003 is different to the others but this year...

Scant information is available on student preferences, behavior, and learning that is accomplished when online assessments are completed either independently or in team settings.  This study investigates the performance of students in a macro-economics principles course that recently adopted online assessment with an "open book, open friend" policy.  Several strategies were developed that encouraged students to learn the material independently.  Data were collected throughout the semester to quantify the number of students who actually did have a friend assist them...

Implementation of subontology of Planning and control for business analysis domain
Provedor de dados: 31
Autores: Atanasova,   Irena.
Ontologies are at the heart of the semantic web. They define the concepts and relationships that make global interoperability possible. However, as these ontologies grow in size they become more and more difficult to create, use, understand, maintain, transform and classify.  As ontologies become common in more applications and as those applications become larger and longer-lived, it is becoming increasingly common for ontologies to be developed in different area of public sector of economics. Ontologies present special challenges to the problem of conceptual modeling.  This paper describes the process of the implementation of a subontology of forecasting and evaluations for business analysis domain in order to develop an easy and correct way to find the...

Autores: Mathews,   Leah Greden.
The benefits that students gain from designing and implementing their own independent undergraduate research projects is often presented as a valuable step in their academic career, and a stepping stone to graduate school success. However, it is not clear what benefits students receive when working as undergraduate research assistants on faculty research projects where they, the students, have little or no input into the project or its design. This paper reports on a survey of undergraduate students who participated as wage laborers on two separate faculty-directed research projects. The results of the study suggest that students gain valuable knowledge and skills that serve as constructive preparation for work, personal lives and graduate school careers;...

RESULTS OF THE NORTH DAKOTA LAND VALUATION MODEL FOR THE 2001 AGRICULTURAL REAL ESTATE ASSESSMENT
Provedor de dados: 31
Autores: Aakre,   Dwight G.; Vreugdenhil,   Harvey G.
This report summarizes the results of the North Dakota Land Valuation Model. This model is used annually to estimate average land values by county, based on the value of production produced on that land. The county land values developed from this procedure form the basis for the 2001 valuation of agricultural land for assessment of real estate taxes. The average all land value from this analysis is multiplied by the total acres of agricultural land on the county abstract to determine each county's total agricultural land value. The State Board of Equalization compares this value with the total value assessed to agricultural property in each county. Each county is required by state statute to assess a total value of agricultural property within 5 percent of...

Enriching Impact Assessment at CIMMYT
Provedor de dados: 31
Autores: La Rovere,   Roberto; Dixon,   John; Hellin,   Jonathan.
The International Center for Maize and Wheat Improvement (CIMMYT) is a CGIAR centre with a long tradition of impact assessment (IA). Until recently, such work had focused on the rates of adoption of improved germplasm and returns on investment. Limited attention was directed at measuring impacts in terms of livelihood security or poverty reduction. In 2005, therefore, CIMMYT's Impacts Targeting and Assessment Unit (ITAU) began to develop and promote more wide-ranging types of IA. In order to enhance its IA culture and institutionalize IA within the Center, ITAU organized a series of workshops that brought together different players amongst CIMMYT's staff and partners. Coupled with follow-up activities, these have made it possible for social and biophysical...

What Can the Poor Expect From Trade Liberalization? Opening the "Black Box" of Trade Modeling
Provedor de dados: 31
Autores: Bouet,   Antoine.
Trade liberalization is expected to act positively on development and poverty alleviation, both of which have become a high priority of international community. This explains why numerous studies have focused on assessing the expected benefits of trade liberalization on poverty. The main empirical tool for these assessments has been the use of multi-country Computable General Equilibrium Models (CGEM). These models, however, have produced divergent results. As demonstrated by recent studies, the associated increase in world welfare from full trade liberalization ranges from 0.2% to 3.1% — results that differ by a factor of 15 to 1! The impact on poverty headcount is also very divergent as the number of people lifted out from poverty ranges from 72 million...

Provedor de dados: 92
Autores: Coswosk,Judson Albino; Soares,Elaine Della Giustina; Faria,Luiz R.R.
ABSTRACT Bait traps are effective and commonly used method in the studies of orchid bees. Important questions in the context of this method, including those related to bait dispersion, how long baits remain attractive, the distance from which males are supposed to be attracted to lures and so on, are still open subjects. Data on the attractiveness of bait traps that have remained in the field during two weeks in a large Atlantic forest preserve are presented. Four main results emerge from the data: (i) the abundance of specimens collected per day decreased in all the attractants as the traps were left on the field; (ii) despite this decrease, the absolute number of individuals collected after eight and fifteen days is remarkably, mostly in eugenol and...

Autores: minteh, mustapha.
Abstract: Maintenance cost of agricultural machines accounts for about 10 to 15% of total production cost and this tends to increase as the machine gets older. To stabilized this already high cost, agricultural machinery maintenance engineers chose Preventive Maintenance (PM) strategy. However, the latter may not produce the desired results especially when machines are used under different operating context. In this paper, an assessment of the effects of PM strategy on reliability indicators (failure rate, mean time between failures (MTBF), mean time to repair (MTTR) and mechanical availability) of a rice combine harvester Mitsubishi TVR96 working under the operating context of Pacharr rice fields in The Gambia, is discussed. These reliability indicators...

Terrestrial impact structures as geoheritage: an assessment method of their scientific value and its application to Brazil
Provedor de dados: 42
Autores: SÁNCHEZ,JOANA P.; BRILHA,JOSÉ B.R.
ABSTRACT Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value should be considered as geological heritage and, consequently, be subjected to geoconservation strategies. In order to select the most important impact structures to be properly conserved and managed, this paper proposes a quantitative assessment method of the scientific value of these structures. The eight Brazilian impact structures were used to test this method that has the potential to be applied to any...
