Mangroves are found throughout the tropics, providing critical ecosystem goods and services to coastal communities and supporting rich biodiversity. Globally, mangroves are being rapidly degraded and deforested at rates exceeding loss in many tropical inland forests. While historically not prominent, mangrove loss in Madagascar’s Mahajamba Bay is increasing.
Eight years of octopus fishery records from southwest Madagascar reveal significant positive impacts from 36 periodic closures on: (a) fishery catches and (b) village fishery income, such that (c) economic benefits from increased landings outweigh costs of foregone catch. We discuss the implications of our findings for broader co-management arrangements, particularly for catalyzing more comprehensive management.
Madagascar’s diverse marine ecosystems serve as critical biodiversity habitats and are also essential to the livelihoods, food security and culture of coastal people, including semi-nomadic Vezo fishers based along the southwest coast.
A report from the ‘Scaling success in octopus fisheries management in the Western Indian Ocean’ workshop held in Zanzibar on 3-5 December 2014, which addresses the key issues faced by small-scale fisheries in the Western Indian Ocean.
Perhaps the most understudied ecosystem services are related to socio-cultural values tied to non-material benefits arising from human–ecosystem relationships. Here we apply a discrete choice experiment (DCE) to determine indigenous fishers’ preferences and willingness-to-pay for bequest gains from management actions in a locally managed marine area in Madagascar, and use our results to estimate an implicit discount rate.
