Wetland socio-ecological systems provide livelihood benefits for many poor people throughout the developing world, yet their sustainable development requires local utilisation strategies that balance both environmental and development outcomes. Community-based local institutional arrangements that mediate peoples’ relationships with their environment and facilitate adaptive co-management offer one means of achieving this, and increasingly many NGOs and development practitioners have sought to integrate local institutional capacity-building into development projects. In the context of wider academic debates surrounding the long-term sustainability of externally-facilitated local institutions, this paper draws on the experiences of the three-year Striking a Balance (SAB) project in Malawi which sought to embed sustainable wetland management practices within community-based local institutional arrangements. Drawing on field data collected through participatory methods at three project sites some five years after the cessation of project activities, we examine the extent to which SAB’s local institutional capacity-building has been successful, and from this draw some lessons for externally-driven project interventions which seek win-win outcomes for people and the environment. With reference to Elinor Ostrom’s design principles for long-enduring common property resource institutions, we suggest that the observed declining effectiveness of SAB’s local institutions can be attributed to issues of stakeholder inclusiveness and representations; their sustainability was arguably compromised from their inception on account of them being nested within pre-existing, externally-driven village ‘clubs’ whose membership and decision-making was not congruent with all the wetland stakeholders within the community.

Las organizaciones son un ente social y económico que según la teoría clásica debe ser vista como una estructura administrativa. Para Mooney (1947) existen principios los cuales baso en la teoría organización, en donde busca establecer relaciones entre principios, procesos y efectos. Por lo que el satisfacer las necesidades de una población debe ser un proceso que involucre intereses particulares .En este caso la organización debe ser estudiada y evaluada como un sistema que tiene diferentes jerarquías y agentes que interactúan entre si, para cumplir un objetivo. Las relaciones que se generan dentro de una organización, y en este caso una organización privada tienden a dar respuesta a muchas necesidades que como procesos se presentan en el diario vivir; es así como se habla del éxito de las organizaciones basado en la competitividad que generan las habilidades y actitudes del personal, el número de variables, fenómenos y efectos, que busca que los empleados asuman actitudes que conlleven a tomar buenas decisiones (Garcia, 2009 ). Es importante resaltar en las organizaciones, los fenómenos de liderazgo, poder e influencia, cada concepto independiente pero visto conjuntamente desde un panorama organizacional, donde toda relación intraespecifica deben determinarse en los diferentes comportamientos, conductas y culturas del personal de la empresa (Fuentes, 2004). La depredación, competencia y cooperación, son conceptos que indudablemente están presentes en todos los procesos de la organización y serán determinantes en la perdurabilidad de la misma. Por último, la presente investigación pretende establecer los efectos de los fenómenos sociales de liderazgo, poder e influencia sobre las interacciones intra-especificas (competencia, cooperación y depredación) al interior de una organización, de tal manera que se logre explicar el efecto y la correlación que existe entre unos y otros fenómenos (Castro, 2012).

En la permanente búsqueda de mejores condiciones que las organizaciones realizan con el propósito de dar respuesta a los cambios del entorno y la complejidad de la interacción con las organizaciones del mismo sector, se encuentra necesario identificar las características que les permiten a estas, sobrevivir, mantenerse en el mercado o crecer en él. En este orden de ideas, en este documento se desarrolla la caracterización de la forma como dos organizaciones importantes y líderes del sector asegurador en Colombia: Seguros Bolívar y Suramericana de Seguros, compiten, desde el punto de vista comercial, con el propósito de identificar como esto influye en cada organización. La investigación se centró en explicar a partir de los autores revisados y analizados con respecto al concepto de la competencia, en particular, la forma como se enfrenta la organización al entorno tanto interno como externo, la influencia de cada organización según su estructura, su importancia, la disponibilidad de los recursos necesarios para desarrollar sus actividades, el impacto y las implicaciones organizacionales a partir de la forma cómo se enfrenta el entorno. Para lo anterior y con base a la revisión conceptual, se realizó la recolección de datos y cifras tanto de las organizaciones como del sector al cual pertenecen, adicionalmente se realizaron entrevistas tanto estructuradas como semi estructuradas al área de ventas, debido a que es el área de las organizaciones encargada de generar estrategias de ventas, posicionar productos en el mercado, identificar el perfil del consumidor, conocer y comprender el mercado y la competencia. Lo anterior con el fin de caracterizar a las organizaciones analizadas, determinando cómo responden a la competencia y al entorno, para finalmente establecer cuáles son los comportamientos recurrentes, similares y diferentes entre ellas. Por lo tanto, los resultados obtenidos en la investigación permiten establecer si dos empresas con estructuras, tamaño y participación en el mercado similares compiten de igual forma y que implicación tiene esto en el comportamiento organizacional.

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

The Corumbau Marine Extractive Reserve was created in a region of rich biodiversity, located in the South of Bahia State, Brazil, to meet the revindications of artisanal fishermen in a context of increasing predatory industrial fisheries. The aim of the Marine Extractive Reserve is to improve the sustainability of fisheries stocks and the economy of artisanal fishermen's families, protecting the local biodiversity for the locals' collective use. However, at Corumbau the natives are facing social problems that have increased due to tourism growth. The present research contributes to the Management Plan in sectors that are crucial to assess the aspirations and subjective aspects related to the natives' daily life at individual, familiar and communitary levels. The Participatory Appraisal with a Gender Equity Perspective (PAGP) was applied to five communities at RESEX Corumbau, showing, by gender, the greatest problems artisanal fisheries' families are facing. Tourism is growing in the area, reflecting the residents different and contradictory interests. It can develop commerce and jobs, but also intensify some social and environmental problems in this area. © Society for Human Ecology.

Trade in non-timber forest products (NTFPs) has been touted as promoting forest conservation and enhancing the well-being of local residents through increased cash income, which is considered a positive outcome. However, research on cooperation has demonstrated that increased market access and income may strengthen or weaken cooperation. Because cooperation is essential for community resilience in small-scale societies, negative effects on people's well-being can be expected if increased NTFP trade reduces cooperation. To evaluate whether NTFP trade affected cooperation, we used household data (survey and systematic observations) to compare the frequency of cooperation in two communities of Brazilian Amazon Caboclos, one of which engaged in NTFP trade, while the other did not. Cooperation was less frequent in the community trading NTFPs, but neither household cash income nor household participation in NTFP exploitation was associated with cooperative behavior. Decreased frequency most likely derived from indirect effects of NTFP trade, such as less time to fish or socialize, or other outcomes observable only at the community level, such as income inequality, the influx of new residents and consequent population growth. Our results indicate that conservation and development projects based on NTFP trade may negatively impact social and economic well-being of local communities.
