Desarrollo de una aplicación web para evaluar cultivos agrícolas a través del método de la MAP.
Provedor de dados: 32
Autores: Vásquez García, Adela.
La Matriz de Análisis de Política (MAP), nos permite determinar la situación actual en cuanto a la competitividad de determinada actividad agrícola y los instrumentos de política que la afectan, aportan elementos para el diseño de políticas diferenciadas, y para identificar los cultivos agrícolas que sean rentables desde los puntos de vista privado y social. En el presente estudio se desarrolló una aplicación web que evalúa cultivos agrícolas a través de la metodología de la MAP. Para conocer la precisión de la aplicación web en cultivos agrícolas, se hizo un ensayo capturando un cultivo de producción de trigo en Guanajuato (Distrito 005 Cortazar), realizado con base a información ya obtenida. Una vez efectuado el análisis se concluyó que la aplicación web...

Modelación hidrogeológica y evaluación de la sustentabilidad del acuífero Cuautitlán-Pachuca.
Provedor de dados: 32
Autores: Neri Ramírez, Efraín.
El acuífero Cuautitlán-Pachuca  ocupa la porción norte de la cuenca del Valle de México, jus¬tificando su nombre por la presencia de Cuautitlán en el Estado de México y Pachuca en el estado de Hidalgo. Dicho acuífero en la actualidad esta sobreexplotado. Por tal motivo en este trabajo se estimó la sustentabilidad del acuífero, utilizando el marco para la evaluación de sistemas de manejo de recursos naturales incorporando indicadores de sustentabilidad (MESMIS). Se realizó un estudio longitudinal comparando dos sistemas, el primero se analizó para el periodo 1970-1990 (sistema de referencia) y el segundo para el periodo 1991-2010 (sistema alternativo). Se analizaron 14 indicadores ambientales, económicos y sociales, para los dos periodos de tiempo....

The notion that effective environmental governance depends in part on achieving a reasonable fit between institutional arrangements and the features of ecosystems and their interconnections with users has been central to much thinking about social-ecological systems for more than a decade. Based on expert consultations this study proposes a set of six dimensions of fit for water governance regimes and then empirically explores variation in measures of these in 28 case studies of national parts of river basins in Europe, Asia, Latin America, and Africa drawing on a database compiled by the Twin2Go project. The six measures capture different but potentially important dimensions of fit: allocation, integration, conservation, basinization, participation, and...

Adaptation of forest management practices in the context of rapid climatic and socioeconomic changes is a global concern. Stakeholders in the forest-based sector as well as policy makers need improved methods and tools to assess potential impacts of changes in management on sustainability indicators. In this special feature, we introduce a methodological framework for classification of forest management approaches in European forestry and explore how changes in forest management might affect the delivery of various ecosystem goods and services and appropriate sustainability indicators over time and space from local to continental scales. The complementary papers in this special feature explore different aspects of sustainability and risks in representative...

Variance as a Leading Indicator of Regime Shift in Ecosystem Services
Provedor de dados: 7
Autores: Brock, William A; University of Wisconsin-Madison; WBrock@ssc.wisc.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
Many environmental conflicts involve pollutants such as greenhouse gas emissions that are dispersed through space and cause losses of ecosystem services.  As pollutant emissions rise in one place, a spatial cascade of declining ecosystem services can spread across a larger landscape because of the dispersion of the pollutant.  This paper considers the problem of anticipating such spatial regime shifts by monitoring time series of the pollutant or associated ecosystem services.  Using such data, it is possible to construct indicators that rise sharply in advance of regime shifts. Specifically, the maximum eigenvalue of the variance-covariance matrix of the multivariate time series of pollutants and ecosystem services rises prior to the regime shift. No...

Responsibility for the management of many protected areas in the Northern Territory, Australia, is shared between the management agency and the aboriginal owners of that land. We describe (1) the creation and types of indicators developed by partners in a participatory process to measure management effectiveness, (2) the assessment method used to monitor progress, and (3) the results of the first cycle of evaluations in four jointly managed parks. Although each pilot park area has distinctive features, we were able to identify a set of twelve common indicators that were applied across the four park areas. The agreed indicators, which were scored using a color scale to indicate level of achievement, were primarily concerned with process rather than outcome,...

New and alternative models for agri-food production and consumption have brought up questions regarding the effects they have on local development processes in terms of the economic exploitation of rural areas as well as environmental, cultural, and social factors. The agri-food system proposed by the Slow Food (SF) Presidia Project, which focuses on farm-to-market systems for local, high-quality, sustainable products, can respond to the new and emerging needs of both rural and urban populaces via several approaches in addition to food production itself. However, evaluating these parameters is challenging. The aim of this study was to develop an indicator-based tool to monitor the sustainability in agri-food systems that considers quality as well as...

Jody; UCLA Fielding School of Public Health ; jody.heymann@ph.ucla.edu.
The need to track climate change adaptation progress is being increasingly recognized but our ability to do the tracking is constrained by the complex nature of adaptation and the absence of measurable outcomes or indicators by which to judge if and how adaptation is occurring. We developed a typology of approaches by which climate change adaptation can be tracked globally at a national level. On the one hand, outcome-based approaches directly measure adaptation progress and effectiveness with reference to avoided climate change impacts. However, given that full exposure to climate change impacts will not happen for decades, alternative approaches focus on developing indicators or proxies by which adaptation can be monitored. These include systematic...

Managing agricultural biotechnology in Colombia
Provedor de dados: 69
Autores: Schuler,Ingrid; Orozco,Luis Antonio.
The international scenario for biotechnology shows a rapid tendency at industrialized countries in the increase of publications, patents, enterprises and novel solutions for the industry, the environment, health and agriculture. Nevertheless, Colombia has an important delay in relation to the international scientific development and the capacity to generate wealth and services for its productive systems. This delay has been one of the concerns of the country's policy during the last years, and more precisely since 2002, when for the first time biotechnology was included in a National Development Plan as one of the mechanisms for competitiveness and the use of biodiversity and genetic resources. This paper is the result of a survey conducted in 2005 aimed...

Models and indicators for assessing conservation and fisheries-related effects of marine protected areas
Provedor de dados: 5
Autores: Pelletier, Dominique; Claudet, Joachim; Ferraris, J; Benedetti Cecchi, L; Garcia Charton, J.
Two kinds of approaches have been used for assessing conservation and fisheries-related effects of marine protected areas (MPAs): (i) statistical modelling based on field data and (ii) mathematical modelling quantifying the consequences of MPAs on the dynamics of populations, communities, and fisheries. Statistical models provide a diagnostic on the impact of MPAs on the ecosystem and resources; they are also needed for devising and assessing sampling designs for monitoring programs. Dynamic models enable exploration of the consequences of MPA designs and other management policies. We briefly review how each of these approaches has been implemented up to now in the literature and identify potential indicators of MPA effects that can be obtained from each...

Indicator-Based Geostatistical Models For Mapping Fish Survey Data
Provedor de dados: 5
Autores: Petitgas, Pierre; Woillez, Mathieu; Doray, Mathieu; Rivoirard, Jacques.
Marine research survey data on fish stocks often show a small proportion of very high-density values, as for many environmental data. This makes the estimation of second-order statistics, such as the variance and the variogram, non-robust. The high fish density values are generated by fish aggregative behaviour, which may vary greatly at small scale in time and space. The high values are thus imprecisely known, both in their spatial occurrence and order of magnitude. To map such data, three indicator-based geostatistical methods were considered, the top-cut model, min–max autocorrelation factors (MAF) of indicators, and multiple indicator kriging. In the top-cut and MAF approaches, the variable is decomposed into components and the most continuous ones...

Towards multidisciplinary indicator dashboards for coral reef fisheries management
Provedor de dados: 5

The diversity of reef ecosystems, the multiplicity of reef resource uses and the breadth of the range of the island socio-cultural contexts concerned make coral reef fisheries (CRF) management in the South Pacific a complex task. The health and state of the targeted resources depend both on ecosystem characteristics (as determined by ecological and biological factors) and on fishing pressure, whose effects are only partly known. Increasing harvests from commercial and recreational fishing increasingly overlap with traditional Subsistence activity, creating an important CRF management challenge. This paper presents a new approach to CRF assessment and monitoring by providing a set of multidisciplinary indicators. The fisheries system is assessed from three...

Small-scale fisheries have traditionally received less research effort than large-scale fisheries and are generally under-studied in Europe. In spite of their comparatively low volume of catches and economic importance, small-scale fisheries are socially important and an integral part of the European coastal zone. Considering the high heterogeneity of situations and the paucity of quantitative data, we used an analytical methodology based on the comparative method. We carried out an analysis of small-scale fisheries (SSFs) in Europe based on a selection of nine case studies. Our objective was to obtain a comprehensive description of small-scale fleets covering different areas/fisheries/species, encompassing the diversity and specific conditions under which...

Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development that are taken into account. The approach adopted in this article is designed to encompass all the dimensions of sustainability including the institutional one (governance). The taking into account of this latter, in particular, together with the role played by aquaculture in sustainability at the territorial level gives the approach its original and innovative nature. The process of establishing the checklist of sustainability indicators in aquaculture relies on a hierarchical nesting approach which...

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.

Impact des mesures de gestion sur la dynamique de la pêcherie pélagique du golfe de Gascogne : Quelles certitudes ? Quels descripteurs ?
Provedor de dados: 5
Autores: Lehuta, Sigrid.
Quantitative evaluations of management measure impact on resource and fleet viability are required to provide diagnostics and feed decision process. Fisheries are complex systems where numerous dynamics interact at various spatial and temporal scales. This complexity and the difficulty to observe marine systems are responsible for the high uncertainty surrounding fishery functioning that makes it hard to identify adequate management measures. The increasing consideration of uncertainties in diagnostics argues in favor of robust management measures rather than optimal management measures. Identifying robust management measures requires the development of models that account for complexity and uncertainty in the description and prediction of management...

We present a method for combining individual indicator results into a comprehensive diagnostic of fishing impacts on fish populations and communities. A conceptual framework for interpreting combined trends in a set of simple indicators is proposed, relying beforehand on qualitative expectations anchored in ecological theory. The initial state of the community is first assessed using published information. Which combinations of trends are acceptable or undesirable is decided, depending on the initial status. The indicators are then calculated from a time-series and their time trends are estimated as the slopes of linear models. Finally, the test results are combined within the predefined framework, providing a diagnostic on the dynamics of fishing impacts...

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing.

Provedor de dados: 5
Autores: Bertrand, Jacques.
Since about twenty years, Ifremer have carried out fishery surveys along the French coasts. A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to these data series. Reference points for non-commercial populations and community indicators are seldom available, but reference directions are well established: it is known whether fishing will increase or decrease the indicator, hence the direction that should be avoided. A set of simple indicators of fishing impacts on fish populations and communities were estimated from time-series data provided by scientific surveys (population abundance and average length, community total biomass and number, average length and weight, and size spectrum). Trends in these indicators...

Whatever their geographical or political point of view, Sea and coastal strategies highlight an “abyssal need” for knowledge and frequently call for a reinforcement and a better valorization of research in Marine Sciences and Technologies (MST). But, when a French public research resources inventory is needed, in the perspective of constructing a consistent action plan, we lack a framework to define thematic and disciplinary perimeter to be taken into account, to identify available data, to choose practical evaluation or estimation methods. The following study is a proposal to answer these questions. The methodology is mainly based on data collected by French High Council for Evaluation of Research and Higher Education (Hcéres) and completed by an inquiry....

Evaluating the potential impact of fishing on demersal species in the Bay of Biscay using simulations and survey data
Provedor de dados: 5
Autores: Ravard, David; Brind'Amour, Anik; Trenkel, Verena.
Fishing affects fish populations through direct and indirect effects. It can change size structures and/or modify population mean weights. Reference values are thus needed to assess the status of populations in exploited ecosystems. These reference values can either be set by a historical approach, i.e. using information from before the onset of exploitation or overexploitation, or by a simulation approach. Using a model based on life-history parameters, we predicted population mean weights and length structures at equilibrium (in the absence of fishing and for fishing equal to different fishing mortalities) which we compared with contemporary data collected during scientific surveys in the Bay of Biscay. Contemporary mean weights were 88% to 30% smaller...

Combining time trends in multiple metrics for identifying persistent changes in population processes or environmental stressors
Provedor de dados: 5
Autores: Trenkel, Verena; Rochet, Marie-joelle.
P&gt;1. Metrics have become a standard way for summarizing environmental monitoring results. Different metrics react differently to natural variations and human-induced stressors. We suggest that combined analysis of time trends in selected biological metrics allows identification of biological processes (e.g. individual growth, mortality or recruitment) that have changed (increased or decreased) persistently. Alternatively, time trends in the abundance of sensitive species could indicate changes in environmental stressors. 2. We calculate the joint likelihood of time trends in three metrics and use it to evaluate the evidence in the data for different combinations of metric time trends. A simulation study provides guidelines for interpreting...

Autores: Pasquaud, Stephanie; Brind'Amour, Anik; Berthele, Olivier; Girardin, Michel; Elie, Pierre; Boet, Philippe; Lepage, Mario.
In view of the European Union (EU) requirements to diagnose and monitor the ecological status of estuarine ecosystems using fish-based indicators, we assessed the effect of the sampling protocol in meeting these objectives. Using three different sampling surveys, we evaluated the impact of four components, i.e. sampling gear, spatial extent, length of time series and temporal window analysed, on the detection of ecological trends in the Gironde estuary, estimated by different types of fish-based indicator. For each component, temporal trends of several fish-based indicators were analysed and for the final diagnosis these temporal trends were combined. The results showed that sampling gear had significant effects on the assessment of ecological trends, as...

From model-based prescriptive advice to indicator-based interactive advice
Provedor de dados: 5
Autores: Trenkel, Verena; Rochet, Marie-joelle; Mesnil, Benoit.
Traditional advice for fisheries management, especially in the ICES world, focuses on short-term stock projections relative to reference points. Primarily, two numbers, spawning-stock biomass and fishing mortality rate, are considered in the advice, although a range of biological processes are included in the stock assessment models. We propose an alternative form of final advice that would not rely on stock predictions and only two numbers, but on a suite of indicators that are combined to provide stock assessment and management advice. For a single stock, the approach consists of monitoring a set of indicators of population state and fishing pressure. Stock reference status at some time in the past is assessed, based on these indicators and/or other...

These last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries.  The aim of this PhD was to use indicators and predictive models for evaluating the impact of the Bonifacio Strait Natural Reserve (Corsica) implementation on fish communities and the benefits of such...

Is a management framework based on spawning-stock biomass indicators sustainable ? A viability approach
Provedor de dados: 5
Autores: De Lara, Michel; Doyen, Luc; Guilbaud, Therese; Rochet, Marie-joelle.
Fisheries management agencies have to drive resources on sustainable paths, i.e. within defined boundaries for an indefinite time. The viable-control approach is proposed as a relevant method to deal with sustainability. We analyse the ICES precautionary approach (PA) by means of the notion of viability domain, and provide a mathematical test for sustainability. It is found that the PA based on spawning-stock biomass (SSB) and fishing mortality (F) indicators is sustainable only when recruits make a significant contribution to SSB. In this case, advice based upon SSB, with an appropriate reference point, is sufficient to ensure sustainability. In all other cases, SSB is not a sufficient metric of stock productivity and must be complemented with other...

The french approach to managing water resources in the mediterranean and the new European Water Framework Directive
Provedor de dados: 5
Autores: Henocque, Yves; Andral, Bruno.
The main content of the new European Water Framework Directive is presented. Within its river basin management approach, a special mention of coastal waters status is made. Among the issues at stake are the setting up of river basin management plans, including coastal waters, and water quality assessment system leading to an harmonized definition of quality objectives and their appropriate indicators. The Rhone-Mediterranean-Corsica Water Master Plan, launched in 1996, is considered to be well fitted to this river basin approach and the necessary tools which go with it. It shows up how a river quality assessment system (SEQ) can be adapted to the coastal waters and how it can progressively lead to an efficient set of publishable environmental and...

Macroalgae delta N-15 values in well-mixed estuaries: Indicator of anthropogenic nitrogen input or macroalgae metabolism?
Provedor de dados: 5
Autores: Raimonet, Melanie; Guillou, Gael; Mornet, Francoise; Richard, Pierre.
Although nitrogen stable isotope ratio (delta N-15) in macroalgae is widely used as a bioindicator of anthropogenic nitrogen inputs to the coastal zone, recent studies suggest the possible role of macroalgae metabolism in delta N-15 variability. Simultaneous determinations of delta N-15 of dissolved inorganic nitrogen (DIN) along the land sea continuum, inter-species variability of delta N-15 and its sensitivity to environmental factors are necessary to confirm the efficiency of macroalgae delta N-15 in monitoring nitrogen origin in mixed-use watersheds. In this study, delta N-15 of annual and perennial macroalgae (Ulva sp., Enterommpha sp., Fucus vesiculosus and Fucus serratus) are compared to delta N-15-DIN along the Charente Estuary, after...

Choosing survey time series for populations as part of an ecosystem approach to fishery management
Provedor de dados: 5
Autores: Trenkel, Verena; Cotter, John.
Ecosystem assessments of fisheries based only on survey data will often have to use surveys that were designed historically for special purposes, e. g. for assessing abundances of two or three target species, or for tuning VPAs. An important question then is whether the previously collected data can provide informative time series of abundance indices and other state indicators for a wider range of target and non-target species. Some potential shortcomings of existing data series are treated in this paper leading to four questions which can guide the user to determine the suitability of an existing time series: did the survey cover the stock of each species adequately? Did survey catchability vary significantly between length or age classes? Did survey...

R.; O'Neill, F. G.; Piet, G. J.; Polet, H.; Sala, A.; Smith, C.; Van Denderen, P. D.; Van Kooten, T.; Zengin, M.
A framework to assess the impact of mobile fishing gear on the seabed and benthic ecosystem is presented. The framework that can be used at regional and local scales provides indicators for both trawling pressure and ecological impact. It builds on high-resolution maps of trawling intensity and considers the physical effects of trawl gears on the seabed, on marine taxa, and on the functioning of the benthic ecosystem. Within the framework, a reductionist approach is applied that breaks down a fishing gear into its components, and a number of biological traits are chosen to determine either the vulnerability of the benthos to the impact of that gear component, or to provide a proxy for their ecological role. The approach considers gear elements, such as...

The deep sea is the largest biome on Earth but the least explored. Our knowledge of it comes from scattered sources spanning different spatial and temporal scales. Implementation of marine policies like the European Union’s Marine Strategy Framework Directive (MSFD) and support for Blue Growth in the deep sea are therefore hindered by lack of data. Integrated assessments of environmental status require tools to work with different and disaggregated datasets (e.g. density of deep-sea habitat-forming species, body-size distribution of commercial fishes, intensity of bottom trawling) across spatial and temporal scales. A feasibility study was conducted as part of the four-year ATLAS project to assess the effectiveness of the open-access Nested Environmental...

Assessment of the ecological status of coastal areas and estuaries in France, using multiple fish-based indicators: a comparative analysis on the Vilaine estuary
Provedor de dados: 5
Autores: Brind'Amour, Anik; Lobry, Jeremy.
When reviewing the various fish-based community indicators aiming at assessing the ecological status of marine communities and/or ecosystems, a typology consisting of three major components emerges. The first component highlights the choice of relevant metrics associated with a level of organization (e. g. population or community). The second relies on the method used to combine the metrics (an aggregated indicator or a synoptic table). The third refers to the type of analysis (direct or indirect) that is used to establish the link between the metrics and a given pressure. In this paper we use the Vilaine coastal-estuarine fish communities as a case study to discuss and relate two different approaches to the suggested typology. The first approach...

A Geostatistical Definition of Hotspots for Fish Spatial Distributions
Provedor de dados: 5
Autores: Petitgas, Pierre; Woillez, Mathieu; Doray, Mathieu; Rivoirard, Jacques.
Research surveys at sea are undertaken yearly to monitor the distribution and abundance of fish stocks. In the survey data, a small number of high fish concentration values are often encountered, which denote hotspots of interest. But statistically, they are responsible for important uncertainty in the estimation. Thus understanding their spatial predictability given their surroundings is expected to reduce such uncertainty. Indicator variograms and cross-variograms allow to understand the spatial relationship between values above a cutoff and the rest of the distribution under that cutoff. Using these tools, a “top” cutoff can be evidenced above which values are spatially uncorrelated with their lower surroundings. Spatially, the geometric set...

La résilience urbaine en question : Enjeux, contexte et propositions d’opérationnalisation
Provedor de dados: 5
Autores: Heinzlef, Charlotte.
Faced with increasing risks, risk management has gradually evolved by integrating new approaches, such as the concept of resilience. An innovative and relevant concept in the systemic approach to risks, resilience is nevertheless struggling to become operational. This term, which has become abstract, is not very appropriate for local actors and often remains at the level of political discourse. The challenge of current research in risk management is therefore to work on the operationalization of the concept by proposing decision support tools. This article presents different methodologies to overcome the abstraction of the concept. From indicators to modeling tools or collaborative approaches, these approaches aim to operationalize resilience concept....

Coastal development, combined with the intrinsic mobility of coasts and the context of climate change, tends to increase the vulnerability of coastal territories. This article proposes, on one hand, a renewed interdisciplinary approach to the concept of vulnerability allowing to overcome the nature/society dichotomy. On the other hand, the paper presents an inter-sectoral researchers-managers approach to build a series of indicators to monitor the four components of systemic vulnerability (hazards, stakes, management and representations). These indicators lay the ground for an integrated observatory, source of data for research as well as to inform decisions regarding the adaptation of coastal territories.

The CUSUM out-of-control table to monitor changes in fish stock status using many indicators
Provedor de dados: 5
Autores: Petitgas, Pierre.
One method to assess fish stocks using a suite of indicators is the traffic light approach. In this approach, the time series of the different indicators are mapped on a common colour scale to highlight alerts that occur when indicators cross reference limit values. Until now, however, the procedure has lacked a statistical framework. Here, we propose the cumulative sum (CUSUM) monitoring scheme as a suitable statistical framework. CUSUM is a statistical process control method that detects deviations from a reference mean, according to defined performance criteria. With the CUSUM monitoring scheme, alarm signals can be triggered when indicators cross defined in-control limits that correspond to defined probabilities of false alarm and non-alarm (i.e.,...

Do explicit criteria help in selecting indicators for ecosystem-based fisheries management?
Provedor de dados: 5
Autores: Rochet, Marie-joelle; Rice, Jake.
An evaluation framework developed to help select an appropriate suite of indicators to support an ecosystem approach to fisheries management was tested experimentally by asking independent experts to weight the selection criteria provided and to score indicators against those criteria in several ecological settings. The steps in selecting indicators proved to be prone to subjectivity and value judgement, and differences in scores between experts were the main factor contributing to variability in evaluation results. Having to justify scores in a written document did not improve consistency among the experts. The framework, however, did enhance transparency by explicitly stating each issue to be addressed in the selection process, and by giving experts or...

An ecosystem-based approach to bivalve aquaculture management is a strategy for the integration of aquaculture within the wider ecosystem, including human aspects, in such a way that it promotes sustainable development, equity, and resilience of ecosystems. Given the linkage between social and ecological systems, marine regulators require an ecosystem-based decision framework that structures and integrates the relationships between these systems and facilitates communication of aquaculture-environment interactions and policy-related developments and decisions. The Drivers-Pressures-State Change-Impact-Response (DPSIR) management framework incorporates the connectivity between human and ecological issues and would permit available performance indicators to...

Underwater acoustics for ecosystem-based management: state of the science and proposals for ecosystem indicators
Provedor de dados: 5
Autores: Trenkel, Verena; Ressler, Patrick H.; Jech, Mike; Giannoulaki, Marianna; Taylor, Chris.
Ecosystem-based management (EBM) requires more extensive information than single-species management. Active underwater acoustic methods provide a means of collecting a wealth of ecosystem information with high space-time resolution. Worldwide fisheries institutes and agencies are carrying out regular acoustic surveys covering many marine shelf ecosystems, but these data are underutilized. In addition, more and more acoustic data collected by vessels of opportunity are becoming available. To encourage their use for EBM, we provide a brief introduction to acoustic and complementary data collection methods in the water column, and review current and potential contributions to monitoring population abundance and biomass, spatial distributions, and...

Probabilistic approach of water residence time and connectivity using Markov Chains with application to tidal embayments
Provedor de dados: 5
Autores: Bacher, Cedric; Filgueira, R.; Guyondet, T.
Markov Chain analysis was recently proposed to assess the time scales and preferential pathways into biological or physical networks by computing residence time, first passage time, rates of transfer between nodes and number of passages in a node. We propose to adapt an algorithm already published for simple systems to physical systems described with a high resolution hydrodynamic model. The method is applied to bays and estuaries on the Eastern Coast of Canada for their interest in shellfish aquaculture. Current velocities have been computed by using a 2 dimensional grid of elements and circulation patterns were summarized by averaging Eulerian flows between adjacent elements. Flows and volumes allow computing probabilities of transition between elements...

We develop a framework for the objective selection of a suite of indicators for use in fisheries management. The framework encompasses eight steps, and provides guidance on pitfalls to be avoided at each step. Step I identifies user groups and their needs, featuring the setting of operational objectives, and Step 2 identifies a corresponding list of candidate indicators. Step 3 assigns weights to nine screening criteria for the candidate indicators: concreteness, theoretical basis, public awareness, cost, measurement, historic data, sensitivity, responsiveness, and specificity. Step 4 scores the indicators against the criteria, and Step 5 summarizes the results. Steps 3-5 offer technical aspects on which guidance is provided, including scoring standards...

Until very recently, governments of many countries, as well as their supporting organizations, have primarily addressed the biological, technical and economic aspects of aquaculture. In contrast, social and cultural aspects of aquaculture production have taken a backseat. Drawing on the observation that aquaculture development in Western Societies has largely failed to address these social effects across different scales and contexts, this paper offers a new way of capturing and visualising the diverse social dimensions of aquaculture. It does so by testing the ability to operationalise a set of social dimensions based on categories and indicators put forward by the United Nations, using several case studies across the North Atlantic.

Estimating productivity of water at different spatial scales using simulation modeling
Provedor de dados: 31
Autores: Droogers,   Peter; Kite,   Geoff.
A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Social sustainability is “one of the three legs of the sustainability stool” (the other two are environmental and economic. There is limited literature that focuses on social sustainability to the extent that a comprehensive study of this concept is still missing. As a result, there have been very few attempts to define social sustainability as an independent dimension of sustainable development. Social sustainability is related to social capital, social inclusion, social exclusion and social cohesion in rural economies, terms that are measured by relevant social sustainability indicators. This paper aims to measure these indicators and to compare them. In order to measure these indicators, a household survey carried out in the context of the research...

The Sustainability and Cost-Effectiveness of Water Storage Projects on Canterbury Rivers: The Opihi River Case
Provedor de dados: 31
Autores: Hearnshaw,   Edward J.S.; Cullen,   Ross.
There is an increasing demand for water resources in the Canterbury region. The impact of this demand has lead to unacceptable minimum river flows, which has resulted in adverse affects to river ecology. In an effort to resolve this problem water storage projects have gained considerable attention. However, in order to consider all values of the impact of water storage projects, a systematic way of implementing an ecosystem services approach is developed. This ecosystem services approach coupled with various appropriate analytical methods are developed for the purposes of evaluating the cost-effectiveness of water storage projects and the sustainability of river systems impacted by water storage projects. For the purposes of evaluating the...

A Global Hunger Index: Measurement Concept, Ranking of Countries, and Trends
Provedor de dados: 31
Autores: Wiesmann,   Doris M.
Progress in combating hunger and undernutrition has been lagging for decades. Best practices to fight hunger and undernutrition have been available for a long while, but lack of political will among leaders and a lack of political power among the poor have hampered their implementation. Since indices have proven to be powerful tools for advocacy and are able to capture multifaceted phenomena, the Global Hunger Index (GHI) was developed to increase attention to the hunger problem and mobilize the political will to speed up urgently needed progress in the fight against hunger. The GHI captures three dimensions of hunger: insufficient availability of food, shortfalls in the nutritional status of children, and child mortality, which is to a large extent...

Autores: Jayne,   Thomas S.; Govereh,   Jones; Chilonda,   Pius; Mason,   Nicole M.; Chapoto,   Antony; Haantuba,   Hyde H.
Effective agricultural and food security policies in Africa need to be based on a solid empirical foundation. In Zambia, it is widely perceived that poverty rates are increasing, agricultural growth is stagnant, and real food prices are higher as food production declines. This study examines these trends and finds that all of these perceptions are wrong. Rural poverty rates have declined substantially in rural Zambia since the early 1990s, although they are still unacceptably high. Real staple food prices for consumers have declined by 20% over the past decade, thanks to major reductions in maize milling and retailing margins. And there is evidence of impressive production growth for some crops that are becoming increasingly important sources of income and...

With high food prices threatening the food security of millions of vulnerable households around the world, hunger and malnutrition are back in the headlines. The world is making only slow progress in reducing food insecurity, according to the Global Hunger Index (GHI). Some regions—in particular South and Southeast Asia, the Near East and North Africa, and Latin America and the Caribbean—have made significant headway in combating hunger and malnutrition since 1990, but in South Asia and Sub-Saharan Africa, the GHI remains high. Moreover, progress in Sub-Saharan Africa since 1990 has been marginal. The GHI is a tool developed by IFPRI for regularly tracking the state of global hunger and malnutrition. This year’s index reflects data until 2006—the most...

Farm Inputs and Agri-Environment Measures as Indicators of Agri-Environment Quality in Hungary
Provedor de dados: 31
Autores: Katona-Kovacs,   Judit; Takacs,   Peter; Szabo,   Gabor G.
The paper deals with agri-environmental indicators, examines farm inputs, on the basis of statistical data of the Organisation for Economic Co-operation and Development (OECD) (Szabo, Pomazi 2002) and the Eurostat (2004). The examined indicators are placed in the agricultural DPSIR model. The paper presents how the use of farm inputs changed in Hungary from 1980-2000. Farm inputs are related to the inputs of the EU-15, the study demonstrates that today they are below the EU- 15 average. Area under agri-environmental measures in 2003 - which covered the 4% of agricultural area of Hungary - as a response indicator is also presented and based in the land-use zone system developed by Godollo Agricultural University (Angyan et al., 1998).

Sustainability assessment of olive grove in Andalusia: A methodological proposal
Provedor de dados: 31
Autores: Gomez-Limon,   Jose Antonio; Riesgo,   Laura.
Recently the olive sector has had important changes in Andalusia due to both the enlargement and the intensification of farming. The expansion of the olive grove in Andalusia is causing sustainability problems, not only from the socio-economic dimension (profit reduction) but environmental (erosion, water pollution or biodiversity losses). The main objective of this study is to develop a methodology to analyse the sustainability of the olive grove farms in Andalusia. This methodology will allow us to bear with the three dimensions of sustainability (economic, social and environmental) as well as to obtain a precise diagnosis of the olive grove through a selection of a set of indicators. This methodology will be applied in future research works in order to...

This paper discusses how environmental indicators and multicriteria methodologies can support the ex post evaluation of Agri-Environmental Schemes. The paper is based on information from the Mid term evaluation of the Rural Development Programmes and develops around an example that compares Ireland and Emilia-Romagna. The results show that the application of Agri-Environmental Schemes only partially achieves to local objectives, and the way in which the Agri-Environmental Schemes are implemented can be reasonably improved. However, the tentative analysis emphasizes the scarcity of quantitative data that can be related to effectiveness, the lack of predetermined quantitatively defined target levels of objectives and the difficulty to assess the relative...

Sigma convergence in Hungarian agriculture
Provedor de dados: 31
Autores: Lamfalusi,   Ibolya.
The present paper provides an analysis of agricultural sigma convergence in four old Member States and in Hungary. The analysis was derived from the output and input data from the Economic Accounts for Agriculture between 1990-2005. The results obtained indicate significant convergence in the old Member States and Hungary. First of all this held true for incomes but the inputs do not reveal a perceptible pattern. However, in terms of outputs Hungary lags well behind the Old Member States, but the difference is not nearly as great for inputs. This can probably be explained by the fact that the rate of increase for inputs is higher than for producer prices, meaning the relative prices of agricultural output and input products (agricultural terms of trade)...

Exploratory Research into the Resilience of Farming Systems during Periods of Hardship
Provedor de dados: 31
Autores: Parsonson-Ensor,   Chris; Saunders,   Caroline M.
This paper investigates the management strategies and responses used by New Zealand sheep and beef farmers to ensure resilience during periods of hardship. Using two, farm level surveys conducted in 1986 and 2010, some aspects of resilient farming systems were identified. Despite apparent hardship current farmers seemed more willing to take risks, with many more borrowing to invest in on farm developments than those in 1986. The main similarity between time periods was the greatest response to economic changes being the adoption of a low input policy. This result was quite significant, as conventional farmers are generally believed to resort to other strategies or responses.

Assessing the Impact of Biodiversity on Tourism Flows: A model for Tourist Behaviour and its Policy Implications
Provedor de dados: 31
Autores: Macagno,   Giulia; Loureiro,   Maria L.; Nunes,   Paulo A.L.D.; Tol,   Richard S.J.
This analysis provides an example of how biodiversity can be measured by means of different indicators, and how the latter can be used to assess the influence of the biodiversity profile of a region on the tourism flows towards it. Previous studies have considered environmental amenities as one of the determinants of tourism destination choice. The central hypothesis of this paper is that the destination’s biodiversity profile can be considered as a key component of environmental amenities. The main objective of this study is to propose a different perspective on this topic, considering the role of biodiversity on tourists’ choice of destination and duration of stay. Domestic Irish tourist flows have been chosen as a case study. The first step of the...

Mapping drought patterns and impacts: a global perspective
Provedor de dados: 31
Autores: Eriyagama,   Nishadi; Smakhtin,   Vladimir U.; Gamage,   Nilantha.
The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

There is a growing recognition that well-defined and enforceable property rights to land are important for a range of economic and social functions. To assess land governance at the country level, the World Bank has elaborated a diagnostic tool based on empirical indicators that aims to identify areas for improvement and that could be used to monitor progress in the land sector. This tool, the Land Governance Assessment Framework (LGAF), was first tested in Peru, Ethiopia, Tanzania, Indonesia and in the Kyrgyz Republic, and is currently being implemented in a number of other countries worldwide. The present paper summarizes the main results obtained from the Kyrgyz pilot to illustrate the case of land governance issues that arise in a post-transition...

A gender performance indicator for irrigation:  Concepts, tools and applications
Provedor de dados: 31
Autores: van Koppen,   Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

Indicators for the assessment of the potential for employment creation in rural areas
Provedor de dados: 31
Autores: Fieldsend,   Andrew F.
The EU Framework 7 project “RuralJobs” has used the DPSIR model to show the link between ‘driving forces’ of employment and economic prosperity, and policy responses. These driving forces can be ‘endogenous’ or (neo-) ‘exogenous’ to the territory. They act on the labour market or employment (‘state’) through the ‘pressures’ of jobs (economic activities) and people (the labour force). In turn, the employment rate (jobs per person) influences the ‘impact’ (sustainable economic prosperity). ‘Responses’ can be policy responses or socio-economic responses. A set of 40 indicators was compiled from strategies and programmes relevant to employment in rural areas in the EU.

A Simple Measure for Agricultural Trade Distortion
Provedor de dados: 31
Autores: Roningen,   Vernon O.; Dixit,   Praveen M.
A simple measure is proposed that estimates the volume of trade distortion caused by the agricultural policies of trading countries. The index, called a TDS (Trade Distorted by support), would be useful for trade analysts to compare the trade impact of agricultural support policies across countries and commodities. The TDS index can be calculated largely from existing information on agricultural support. A TDS index might also be used to assess damages in trade dispute settlement cases.

Abstract The importance of physicals properties of soil has an appreciable influence on their functions, water quality, climate control, nutrient cycling, and biodiversity, among others. These provide more ecosystem functions than just the nutritional contribution to agricultural production. Currently, the soil is under management pressure to the food production energy and raw material, which has led to its physical deterioration and degradation. The objective of this study is to evaluate the effects of bulk density and soil aggregate size silvopastoral systems (from tropical dry forest pastures) on the growth of guinea grass (Megathyrsus maximus) cv.

Heritage and patrimony of the peasantry framework to address rural development and its application in Colombia
Provedor de dados: 109
Autores: Pachón Ariza,Fabio Alberto; Bokelmann,Wolfgang; Ramírez Miranda,César Adrián.
Abstract The theoretical framework “heritage and patrimony of the peasantry” and its suggested operationalization potentially offers an improvement over previous approaches to analyse rural development. The first application of the concept was carried out in Colombia, quantifying rural development indicators in six rural territories. The most critical indicators to define rural development in this context were identified as follows: biodiversity, recycling and communal values. Based on these findings, human patrimony has the lowest level of all the heritages of the Colombian peasantry. Public policies to overcome these matters in the post-conflict era, should be the priority of rural development strategies.

The thermoneutral zone is defined as the range of ambient temperature within which metabolic rate is at a minimum, and within which temperature regulation is achieved by non-evaporative physical processes alone. As temperature raises, animals the upper critical temperature is reached, which is the ambient temperature above which thermoregulatory evaporative heat loss processes of a resting thermoregulating animal are recruited. These temperatures depend on a variety of factors including animal species and breed, age, adaptation or animal status, among others. These are influenced by other environmental conditions such as...

Groundwater resources in the State of São Paulo (Brazil): the application of indicators
Provedor de dados: 42
Autores: Hirata,Ricardo; Suhogusoff,Alexandra; Fernandes,Amélia.
Indicators, for groundwater resources, have mostly been employed to define the present status and the degradation tendency, regarding both quantity (under- or overexploitation) and quality (natural and anthropic contamination). This work presents the application of indicators in order to draw a picture of the groundwater resources situation in the 22 Water Resource Management Units (WRMU) of the State of São Paulo. The seven Indicators (I1 to I7) applied provide a general overview of groundwater dependence (I1, I2), availability (I3, I4), and quality (I5, I6, I7). Considering public supply (Indicator 1), one observes that 9 WRMUs show high (&gt;50% of the population supplied by groundwater), 6, intermediate (49-25%), and 7, low (&lt;24%) dependence on...

Good agricultural practices in broiler chicken production in the state of Paraná: focus on animal welfare
Provedor de dados: 65
Autores: Souza,Ana Paula Oliveira; Molento,Carla Forte Maiolino.
ABSTRACT: Broiler chicken welfare regulation at farm level is scarce in Brazil. This research aimed to study good agricultural practices at farm level adopted by broiler chicken companies in the state of Paraná, analyzing them in relation to the promotion of animal welfare. Twenty exporting companies were contacted, 15 answered the questionnaire. The participating companies were responsible for 76.3% of the State broiler production. Indicators related to the availability and the quality of food and water are being adapted by the companies, but still need to be improved. Regarding environmental indicators, companies had concerns about air and litter quality and about the implementation of emergency systems on totally enclosed broiler houses. Natural light...
