Community-based natural resource management in Roatan: Strengths and challenges.

This study explored the transformative journey of community-based natural resource management (CBNRM) in the Bay Islands National Marine Park, Honduras, revealing the interplay of cooperation, funding, and communication in fostering successful conservation initiatives. Using a mixed-method approach, we investigated the historical and legislative process and enabling conditions that led to the transition to CBNRM, based on Gruber's 12 key principles. In regards to the present CBNRM system, we looked at its strengths, its challenges, and whether its functioning is seen as satisfying by local resource-users. Findings showed that key CBNRM principles-including an enabling environment, conflict resolution, research-based decision-making, public trust, and monitoring-fostered the transition. Furthermore, satisfaction with reef management and perceived patrol effectiveness, which are pivotal aspects in CBNRM, exceeded 70% in Roatan. Challenges such as strengthening local institutions and enhancing compliance were identified. Nonetheless, co-managers are actively working to resolve these challenges by focusing on enforcement, diverse funding acquisition mechanisms and community participation. The study underscores the pivotal role of local NGOs and collaborative committees in facilitating successful CBNRM. By providing evidence-based insights, we highlight the efficacy of multilevel, co-management models in resource management and emphasize the value of adaptable strategies. These findings contribute to a deeper understanding of CBNRM dynamics in Latin America and the Caribbean, which may ultimately foster successful conservation initiatives in the Global South.

Design trade-offs in rights-based management of small-scale fisheries.

Small-scale fisheries collectively have a large ecological footprint and are key sources of food security, especially in developing countries. Many of the data-intensive approaches to fishery management are infeasible in these fisheries, but a strategy that has emerged to overcome these challenges is the establishment of territorial user rights for fisheries (TURFs). In this approach, exclusive fishing zones are established for groups of stakeholders, which eliminates the race to fish with other groups. A key challenge, however, is setting the size of TURFs-too large and the number of stakeholders sharing them impedes collective action, and too small and the movement of target fish species in and out of the TURFs effectively removes the community's exclusive access. We assessed the size of 137 TURFs from across the globe relative to this design challenge by applying theoretical models that predict their performance. We estimated that roughly two-thirds of these TURFs were sized ideally to overcome the challenges posed by resource movement and fisher group size. However, for most of the remaining TURFs, all possible sizes were either too small to overcome the resource-movement challenge or too large to overcome the collective action challenge. Our results suggest these fisheries, which target mobile species in densely populated regions, may need additional interventions to be successful.

Diseño de Compensaciones en la Administración Basada en Derechos de las Pesquerías de Pequeña Escala Resumen Las pesquerías de pequeña escala tienen una gran huella ecológica de manera colectiva y son fuentes importantes de seguridad alimenticia, especialmente en los países en desarrollo. Muchas de las estrategias cargadas de datos para la administración de las pesquerías son inviables en este tipo de pesquerías, pero una estrategia que ha emergido para sobrellevar estos retos es el establecimiento de los derechos de uso territorial para las pesquerías (TURFs, en inglés). Como parte de esta estrategia se establecen zonas exclusivas de pesca para los grupos de accionistas, lo que elimina la competencia por la pesca con otros grupos. Sin embargo, un reto importante es el establecimiento del tamaño de los TURFs - si son muy grandes, el número de accionistas que los comparten impide la acción colectiva; si son muy pequeños, el movimiento de las especies diana de peces dentro y fuera de los TURFs le retira efectivamente el acceso exclusivo a la comunidad. Evaluamos el tamaño de 137 TURFs ubicados en todo el mundo en relación con este reto del diseño aplicando modelos teóricos que pronosticaron su desempeño. Estimamos que aproximadamente dos tercios de estos TURFs tenían el tamaño ideal para superar los retos que presentan el movimiento del recurso y el tamaño del grupo pesquero. Sin embargo, para la mayoría de los TURFs restantes todos los tamaños posibles eran o muy pequeños para superar el reto del movimiento del recurso, o muy grandes para sobrellevar el reto de la acción colectiva. Nuestros resultados sugieren que estas pesquerías que se enfocan en especies móviles dentro de regiones pobladas densamente pueden requerir de intervenciones adicionales para ser exitosas.
