The Global Programme “Sustainable Fisheries and Aquaculture”, implemented by GIZ, aims to increase fish supply from sustainable and resource-friendly fisheries and aquaculture to boost a healthy and diverse nutrition. The solution presented here supports sustainable fishing practices in artisanal fishing communities and preserves aquatic resources. It combats illegal, unreported, and unregulated (IUU) fishing by establishing multi-stakeholder platforms (MSPs) to develop a legal framework for sustainable fisheries management. The project also provides training to fishers on legal fishing practices, implements a robust registration and licensing system, and builds cooperative community-based management structures. It improves patrol quality and conducts public campaigns to raise awareness about sustainable fishing practices and the dangers of IUU fishing. These efforts help restoring fish populations, stabilize the fishing sector’s profitability, and improve the livelihoods and safety of fishing communities.
