A COMPARISON ON FARMERS’ PARTICIPATION IN FARMERS’ ORGANIZATIONS AND IMPLICATIONS FOR RURAL EXTENSION IN MINAS GERAIS

Boas, Ana Alice Vilas; Goldey, Patricia.

This paper describes a comparison on farmers’ participation in farmers’ organisations and attempts to explain why they prefer to carry out production and marketing activities by themselves. It also examines the implications of the findings for rural extension and related services. A total of 122 interviews were conducted with different categories of farmers and with the extension workers. The comparative analysis of two case studies (Cruz Alta and Pantano) showed that socio-economic characteristics were not very significant in determining the level of farmers’ participation in farmers’ organizations in Minas Gerais. The ability of managers emerged as one of the most important factors in the success or failure of farmers’ organizations. The presence of...

A MINŐSÉGMENEDZSMENT A HAZAI BAROMFI-FELDOLGOZÁSBAN

Vermard, Youen; Marchal, Paul; Mahevas, Stephanie; Thebaud, Olivier.

The scope of this paper is to describe, evaluate, and forecast fishing trip choices of the Bay of Biscay pelagic fleet using random utility modeling (RUM). First, alternative fishing trip choices of this fleet were identified using multivariate statistical methods based on species landings weighted by value and defined as distinct fishing activity or fisheries (termed metiers). A RUM was specified, which included trip components as attributes during the period 20012004 ( a lagged percentage of the value per unit of effort of the main species caught, total value per unit of effort, and inertia in terms of changes from one metier to another). For the main metiers, the proportion of correct effort allocation is 90% during the calibration period of 2001-2004....

A New Methodology for Assessing the Effectiveness of Marine Protected Areas

Mikaczo, Andrea.

A vizsgálatok alapján megállapítható, hogy a magyar baromfi-feldolgozó iparág megfelelően teljesíti mind a hazai, mind az EU-s előírásokat, követelményeket. Az élelmiszerbiztonsági előírásoknak való megfelelés valamennyi érintett vállalkozásban elsődleges szempont. A magas minőségi színvonal elérésére és teljesítésére irányuló további módszereket, mint pl. az integrált menedzsment irányítási rendszereket is alkalmazzák a vállalkozások, de az ezekre való törekvést nem a vállalat belső igénye, hanem a piac indukálja. Remélhetőleg a jövőben egyre több élelmiszeripari vállalkozás ismeri fel az ISO 22000 szabvány alkalmazásának előnyeit, ami ötvözi a HACCP és az ISO 9001 alkalmazását, és kifejezetten az élelmiszeripari termelésre specializált szabványként...

La efectividad de manejo se entiende como el grado en que los objetivos de manejo de un área protegida han sido cumplidos. Antes del 1993 no existían en la literatura trabajos sobre este tema, y solo se encontraban artículos que trataban sobre los objetivos y beneficios de las áreas protegidas vistos desde una perspectiva biológica solamente. En el presente trabajo se desarrolla una nueva metodología para evaluar la efectividad de manejo de un área marina protegida y la misma se aplica a un estudio de caso real. La metodología propuesta constituye una herramienta interdisciplinaria que pudiera mejorar el manejo de las áreas marinas protegidas. Esta metodología constituye un paso adelante que se nutre de las contribuciones anteriores y provee un nuevo...

A New Paradigm for Adaptive Management

Ecology and Society

Felton, Adam; Southern Swedish Forest Research Centre, Swedish University of Agricultural Sciences; adam.felton@slu.se; Rosvall, Ola; Rosvall Forest Consulting AB; Ola.rosvall@gmail.com.

Uncertainty is a pervasive feature in natural resource management. Adaptive management, an approach that focuses on identifying critical uncertainties to be reduced via diagnostic management experiments, is one favored approach for tackling this reality. While adaptive management is identified as a key method in the environmental management toolbox, there remains a lack of clarity over when its use is appropriate or feasible. Its implementation is often viewed as suitable only in a limited set of circumstances. Here we restructure some of the ideas supporting this view, and show why much of the pessimism around AM may be unwarranted. We present a new framework for deciding when AM is appropriate, feasible, and subsequently successful. We thus present a new...

A Participatory Modeling Process to Capture Indigenous Ways of Adaptability to Uncertainty: Outputs From an Experiment in West African Drylands

Ecology and Society

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...

Abundance, feeding and reproduction of Salminus sp. (Pisces: Characidae) from mountain streams of the Andean piedmont in Venezuela

Neotropical Ichthyology

Rodríguez-Olarte,Douglas; Taphorn B.,Donald C..

To obtain basic information for management, aspects of the ecology of Salminus sp. (Pisces: Characidae), were studied in piedmont rivers of the southwestern flank of the Andes in Venezuela. Collections were made with seines of various lengths and mesh sizes, and both underwater and terrestrial observations were recorded to estimate abundance and feeding events. Interviews with local fishermen and inhabitants were made to obtain data on use. The species is present along the entire length of the Andean piedmont in Venezuela, although in some rivers it is now scarce. Small individuals form mixed schools with Brycon whitei, but larger Salminus sp. usually only school with others of the same species. Average abundance was greater in larger rivers, and didn't...

Addressing surprise and uncertain futures in marine science, marine governance, and society

Bretagnolle, Vincent; Benoit, Marc; Bonnefond, Mathieu; Breton, Vincent; Church, Jon M.; Gaba, Sabrina; Gilbert, Daniel; Gillet, François; Glatron, Sandrine; Guerbois, Chloé; Lamouroux, Nicolas; Lebouvier, Marc; Mazé, Camille; Mouchel, Jean-marie; Ouin, Annie; Pays, Olivier; Piscart, Christophe; Ragueneau, Olivier; Servain, Sylvie; Spiegelberger, Thomas; Fritz, Hervé.

Many social-ecological system(SES)-based approaches have been proposed to address environmental problems. Most social-ecological frameworks developed to date, however, lack clear operational linkages between humans and nature to efficiently guide SESs toward resilience. A conceptual framework designed to be operational is therefore necessary, as well as a network of research platforms with which to apply it. We defined explicit coupling processes that can be used as leverages to pilot an SES toward sustainability. We proposed to formalize an SES as a dynamic entity composed of two coupling interfaces, i.e., adaptive management and ecosystem services, both set within a landscape context to provide an actionable framework. These interfaces describe the way...

On an increasingly populated planet, with decreasing biodiversity and limited new opportunities to tap unexploited natural resources, there is a clear need to adjust aspects of marine management and governance. Although sectarian management has succeeded in addressing and managing some important threats to marine ecosystems, unintended consequences are often associated with overlooking nonlinear interactions and cumulative impacts that increase the risk of surprises in social-ecological systems. In this paper, we begin to untangle science-governance-society (SGS) interdependencies in marine systems by considering how to recognize the risk of surprise in social and ecological dynamics. Equally important is drawing attention to our state of preparedness,...

Adoption of Bt Cotton: Threats and Challenges

Chilean J. Agric. Res.

Faisal Bilal,Muhammad; Farrukh Saleem,Muhammad; Ashfaq Wahid,Muhammad; Shakeel,Amir; Maqbool,Mudassar.

Adopting new technology always involves advantages and risks; Bt cotton (Gossypium hirsutum L.) is a new technology well known in developed countries for its many advantages, such as reduced pesticide application, better insect pest control, and higher lint yield. However, its success in developing countries is still a question mark. Global adoption of Bt cotton has risen dramatically from 0.76 million ha when introduced in 1996 to 7.85 million ha in the 2005 cotton-growing season where 54% of the cotton crops in the USA, 76% in China, and 80% in Australia were grown with single or multiple Bt genes. Bollworms are serious cotton pests causing 30-40% yield reduction in Pakistan and 20-66% potential crop losses in India. The major advances shown in this...

AGRICULTURAL COOPERATIVE MANAGERS AND THE BUSINESS ENVIRONMENT

Adrian, John L., Jr.; Green, Thomas Wade.

Managers of agricultural cooperatives were contacted to determine their knowledge/capabilities and perspectives of the cooperative environment with special emphasis given to the importance of cooperative principles to the operation and success of the business, division of responsibility between management and the board of directors, and business decision making in the areas of financial analysis plus selected scenarios. Managers showed strong adherence to traditional cooperative principles and basic decision areas. Self-assessments were positive and consistent with performance measures. The opportunity exists to improve manager knowledge/capabilities related to cooperative principles, division of responsibility between managers and the board, and financial...

Agroforestry system as a buffer zone in a Brazilian Atlantic Forest conservation unit: an artificial nest predation perspective

Biota Neotropica

Galvão,Camila André; Francisco,Mercival Roberto; Schlindwein,Marcelo Nivert.

Abstract Here we inferred about the effectiveness of a buffer zone composed by an Agroforestry System (AS) for providing reproductive conditions for Atlantic Forest birds by comparing artificial nest predation rates between a buffer zone, a primary forest area, and a set of small and isolated Atlantic Forest fragments. We have used 237 nests throughout the three areas, of which 100 (42.2%) were depredated. Predation frequencies were 28.6% in the continuous forest, 100% in the AS, and 51.9% in the fragments, differing significantly. We could detect nest predators in 48 of the 100 depredated nests (48%) using camera traps. Differences between areas may be attributed to changes in nest predator species. We support previous evidences that the conservation of...

Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs

Algunas consideraciones sobre manejo del suelo y del agua para el desarrollo de la agricultura tradicional en el Noreste de Brazil.

Claudet, Joachim.

Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...
