São Tomé and Príncipe, located in the Gulf of Guinea, on the western equatorial coast of Central Africa, is a global biodiversity hotspot, with a high degree of endemism. However, both islands face challenges related to overfishing and widespread habitat degradation. Bringing together a consortium of national and international NGOs, in partnership and under the guidance of the Fisheries and Aquaculture Directorate of the Ministry of Agriculture and other government authorities, Rural Development and Fisheries, in dialogue with the Environment Directorate of the Ministry of the Environment, the project contributes to improving local livelihoods through the promotion of responsible fishing practices and investments in the supply chain. The project aims to facilitate participatory mapping of MPAs and sustainable use zones. It is also supporting the development of monitoring protocols and develops patrol skills to enable fishermen and the relevant government authorities to monitor co-managed areas.
