A predictive index based on environmental filters for the bioassessment of river basins without reference areas in Atlantic Forest biome, Brazil Biota Neotropica
Souza,Natália Freitas de; Baptista,Darcílio Fernandes; Buss,Daniel Forsin.
Abstract: Biological assessments that use the reference condition approach are based on the concept of comparing a site's observed biology to sites where disturbance is minimal or absent. However, in many regions of the world, such areas are scarce or nonexistent. In this study, an alternative approach proposed by Chessman and Royal for bioassessment without reference areas based on environmental filters was tested in Brazil. This approach assumes that key environmental features act in the selection of potential colonists, from a regional pool of taxa, based on the ecological traits (tolerances) possessed by each taxon. We developed the approach by: 1) determining the regional pool, based on a large Atlantic Forest biome database; 2) selecting...

A proposed ecosystem-based management system for marine waters: linking the theory of environmental policy to the practice of environmental management Ecology and Society
O'Higgins, Tim; Scottish Association for Marine Science (SAMS), Scottish Marine Institute, Scotland; Tim.O'Higgins@sams.ac.uk; Cormier, Roland; Gulf Fisheries Centre, Fisheries and Oceans Canada; Roland.Cormier@dfo-mpo.gc.ca; Diedrich, Amy; School of Earth and Environmental Sciences, James Cook University, Australia; amy.diedrich@jcu.edu.au.
New coastal and marine management strategies have recently been developed in many countries and regions. From an ecosystem approach perspective, the aim of such strategies is the maintenance of ecosystem integrity while enabling the sustainable use of ecosystem goods and services. There is, however, a need for harmonized definitions and standardized processes to deal not only with the interjurisdictional and multidisciplinary complexities that are associated with such strategies but also with the extensive timelines and resources implicated in the planning and implementation of these strategies. The ecosystem-based management system proposed here is based on three pillars that facilitate the integration of an ecosystem approach to coastal and oceans policy...

A Reconsideration of Environmental Federalism AgEcon
Oates, Wallace E..
This paper provides a review and assessment of the debate over environmental federalism-the issue of the roles of different levels of government in environmental management. The paper begins with the presentation of three benchmark cases that provide a framework for thinking about the issue. It then offers a review, first of the theoretical literature and second of some new, provocative empirical literature on the race to the bottom. The paper contends that there remains, under certain circumstances, an important role for decentralized government in the setting of environmental standards and the design of regulatory programs. The central government, in addition to setting standards for "national" pollutants, has a fundamental contribution to make in...

A Revised Conceptual Framework for Payments for Environmental Services Ecology and Society
Sommerville, Matthew M.; Department of Life Sciences, Imperial College London; m.sommerville06@imperial.ac.uk; Jones, Julia P. G.; School of Environment and Natural Resources, University of Bangor; julia.jones@bangor.ac.uk; Milner-Gulland, E. J.; Department of Life Sciences, Imperial College London; e.j.milner-gulland@imperial.ac.uk.
Over the past decade, “Payments for Environmental Services” (PES) have received a great deal of attention as a natural-resource management approach. We propose a revised definition and framework for PES implementation that focuses on the use of positive incentives as the philosophy behind PES and conditionality as the method for influencing behaviors. We note the importance of additionality of PES interventions to justify their value in a wider context. Finally, we highlight the need to understand the local institutional context in terms of the characteristics of buyers, sellers, and their relationship for implementation to be effective. Our framework acts as a platform to begin examining how the variety of options for structuring PES...

A Tool and Process that Facilitate Community Capacity Building and Social Learning for Natural Resource Management Ecology and Society
Raymond, Christopher M; Institute for Land, Water and Society, Charles Sturt University; Enviroconnect Pty Ltd; chris.raymond@enviroconnect.com.au; Cleary, Jen; Centre for Rural Health and Community Development, University of South Australia; jen.cleary@unisa.edu.au.
This study presents a self-assessment tool and process that facilitate community capacity building and social learning for natural resource management. The tool and process provide opportunities for rural landholders and project teams both to self-assess their capacity to plan and deliver natural resource management (NRM) programs and to reflect on their capacities relative to other organizations and institutions that operate in their region. We first outline the tool and process and then present a critical review of the pilot in the South Australian Arid Lands NRM region, South Australia. Results indicate that participants representing local, organizational, and institutional tiers of government were able to arrive at a group consensus position on the...

Adaptive Management Planning Projects as Conflict Resolution Processes Ecology and Society
Walkerden, Greg; Macquarie University; gmw@bwassociates.com.au.
Adaptive management planning projects use multiparty, multidisciplinary workshops and simulation modeling to facilitate dialogue, negotiation, and planning. However, they have been criticized as a poor medium for conflict resolution. Alternative processes from the conflict resolution tradition, e.g., principled negotiation and sequenced negotiation, address uncertainty and biophysical constraints much less skillfully than does adaptive management. When we evaluate adaptive management planning using conflict resolution practice as a benchmark, we can design better planning procedures. Adaptive management planning procedures emerge that explore system structure, dynamics, and uncertainty, and that also provide a strong negotiation process, grounded in...

Adoption of cleaner production practices by dairy farmers in southern Chile Ciencia e Investigación Agraria
Nahuelhual,Laura; Engler,María A; Carrillo,Bernardo; Moreira,Víctor; Castro,Ingrid.
Rising concerns about the environmental costs of dairy production have resulted in an increasing use of farm practices that diminish negative production externalities. Yet, little empirical evidence exists regarding the factors influencing the adoption of pollution-reducing strategies by dairy farmers. In this study, we estímate a logit probability model to explain first-stage adoption of capital-intensive cleaner production (CP) practices, using a sample of 100 médium and large-size dairy farms located in southern Chile. Voluntary approaches to pollution control in agriculture are relatively recent in Chile and diffusion has been slow and uneven among farmers. Only 43% of the farmers surveyed were using some CP practices at the time of the interview. The...

An experimental comparison of three Towed Underwater Video Systems using species metrics, benthic impact and performance ArchiMer
Sheehan, Emma V.; Vaz, Sandrine; Pettifer, Erin; Foster, Nicola L.; Nancollas, Sarah J.; Cousens, Sophie; Holmes, Luke; Facq, Jean-valery; Germain, Gregory; Attrill, Martin J..
Managing ecological systems, which operate over large spatial scales, is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable, but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (TUVSs) were experimentally compared. Three technically different TUVSs were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine Conservation Zone, off the south coast of England. For each TUVS, species metrics (forward facing camera), seabed impact (backward facing camera) and operational performance (strengths and limitations of equipment and video...

Best management practices and environmental management in aquaculture: indicators for monitoring in multiple scales. Repositório Alice
RODRIGUES, G. S.; QUEIROZ, J. F. de; FRIGHETTO, R. T. S.; SAMPAIO, F. G.; FRASCÁ-SCORVO, C. M. D.; COUTO, K. R.; RODRIGUES, I. A..
Abstract: The promotion of sustainable aquaculture depends on the documented adoption of Best Management Practices (BMPs), associated with the monitoring of environmental health, of the availability of natural resources (especially uncontaminated waters and sediments), and of the efficient use of inputs. In order to ensure a traceable and organized procedure to help fish farmers to comply with these requisites, a set of environmental performance indicators has been integrated into an Environmental Impact Assessment (EIA) system, under the coordination of the Brazilian Ministry of Fisheries and Aquaculture (MPA), through a research project carried out in the Furnas reservoir (Minas Gerais State, Brazil). This choice of location aims at supporting a national...

Causes of Diversification in Agriculture Over Time: Evidence From Norwegian Farming Sector AgEcon
Culas, Richard J.; Mahendrarajah, Mahen.
Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread...

Choosing the best non-parametric richness estimator for benthic macroinvertebrates databases Rev. Soc. Entomol. Argent.
Basualdo,Carola V..
Non-parametric estimators allow to compare the estimates of richness among data sets from heterogeneous sources. However, since the estimator performance depends on the species-abundance distribution of the sample, preference for one or another is a difficult issue. The present study recovers and revalues some criteria already present in the literature in order to choose the most suitable estimator for streams macroinvertebrates, and provides some tools to apply them. Two abundance and four incidence estimators were applied to a regional database at family and genus level. They were evaluated under four criteria: sub-sample size required to estimate the observed richness; constancy of the sub-sample size; lack of erratic behavior and similarity in curve...

Companies and Regulators in Emissions Trading Programs AgEcon
Kruger, Joseph.
Much has been written about the economic and environmental performance of U.S. emissions trading programs for "acid rain" (sulfur dioxide) and nitrogen oxides. Less explored have been the unique roles and interactions of environmental regulators and the companies they regulate. I first examine how these roles change the way that regulators and companies operate within their own organizations and with each other. Next, I use examples from U.S. trading programs to illustrate the design and administrative features that allow program administrators and industry to best fulfill their respective roles. Finally, I examine briefly whether these features are present in the EU Emissions Trading System and determine the implications for its effectiveness.

Corporate Codes of Conduct: Is Common Environmental Content Feasible? AgEcon
Fischer, Carolyn; Parry, Ian W.H.; Aguilar, Francisco X.; Jawahar, Puja.
In a developing country context, a policy to promote adoption of common environmental content for corporate codes of conduct (COCs) aspires to meaningful results on two fronts. First, adherence to COC provisions should offer economic benefits that exceed the costs of compliance; i.e., companies must receive a price premium, market expansion, efficiency gains, subsidized technical assistance, or some combination of these benefits in return for meeting the requirements. Second, compliance should produce significant improvements in environmental outcomes; i.e., the code must impose real requirements, and monitoring and enforcement must offer sufficient incentives to prevent evasion. With those goals in mind, we explore options for establishing common...
