These trust funds are independent entities financed by a range of international and national sources. As of April 2015, total commitments to endow Mauritania’s trust fund (BACoMaB) had reached EUR 22.3 million, with funds sourced from the Mauritanian Government via the EU FPA as well as from a range of international donors. Guinea-Bissau’s more recent BioGuinea Foundation, established in 2011, has received commitments of EUR 5 million, including EUR 1 million from the Guinea-Bissau government. Building a shared understanding of the economic benefits that marine conservation can bring to the fisheries sector was vital. This required lobbying, consensus building and co-ordination by non-government organisations (NGOs) acting as brokers. Both cases also highlight the importance of a secure legal and institutional basis for MPA management and financing to prevent wavering political support and changing priorities threatening the long-term stability of conservation financing.
