PROA STP – Artisanal Fisheries Modernisation Programme is a structural project designed to profoundly transform the fishing sector in São Tomé and Príncipe, modernising the fleet, strengthening coastal infrastructure and professionalising the entire value chain. In a country whose Exclusive Economic Zone is 160 times larger than its territory, the project responds to critical challenges – obsolete fleet, lack of a functional port, almost non-existent cold chain and regulatory limitations – by offering an integrated solution that combines new vessels, traceability, environmental sustainability, effective governance and socio-economic inclusion. Anchored in the priorities of the PNIEA and the BEFIRM programme, PROA STP aims to reduce post-harvest losses, increase incomes, improve safety at sea and consolidate the sector's climate resilience, positioning fisheries as a true driver of the Blue Economy and national food security. Structured around four components — port and cold storage infrastructure, fleet and value chain renewal, conservation and sustainability, and strengthening of control and surveillance (MCS) — the project mobilises €23.5 million in direct investments and a total amount of €31.5 million, with the support of the AfDB, GEF, PNIEA, the Government and partners such as XSEALENCE. The expected benefits are transformative: post-harvest losses reduced to less than 15%, a 20–30% increase in valued production, the creation of more than 500 direct and 3,000 indirect jobs, full fleet traceability by 2030, and enhanced economic inclusion with ≥40% female participation. With sanitised markets, ice factories, cold rooms, a semi-industrial fleet, VMS/AIS, MONICAP™ Micro VMS and restoration of mangroves and coastal habitats, PROA STP represents a long-lasting impact investment, offering food security, ecological sustainability and real economic growth for the fishing communities of the two islands.
