摘要

Mangrove ecosystems are vital to coastal communities, providing essential resources that support livelihoods. This study examines the ethnoecological importance of mangroves in Andrevo and Ambondrolava, southwestern Madagascar, by assessing patterns of resource use and analyzing community-based management strategies, together with their ecological outcomes and associated challenges. A mixed-methods approach, combining questionnaire surveys, focus group discussions, and forest inventory assessments, was applied. The results show that mangroves are key resources for house construction, traditional medicine, fishing materials, and fuelwood in both study areas. The implementation of community-based mangrove management (CBMM) appears to have contributed to forest recovery, as evidenced by higher stem density and natural regeneration. Most households also reported an expansion of mangrove cover over the past decade, largely attributed to local conservation and restoration efforts. However, the effectiveness of CBMM is constrained by insufficient institutional support, weak enforcement of regulations at the community level, inconsistencies between statutory laws and customary governance systems, and restoration practices that often rely on one or two species planted in ecologically unsuitable locations. These findings highlight the close relationship between local communities and mangroves in southwestern Madagascar and underscore the key challenges facing local mangrove management and governance.
