Mexico’s progress towards meeting the Aichi Targets includes the expansion of the protected area system. Unfortunately, the budget of the National Commission for Protected Areas (CONANP) is not keeping pace, resulting in chronically underfunded protected areas. Thus, supplementary funding from private, bilateral and multilateral donors is crucial for their effective operation. In order to address lacking financial resources and to ensure long-term sustained funding, the Mexican Fund for the Conservation of Nature (FMCN) and CONANP created the Fund for Protected Areas to support the management of 29 federal protected areas. Based on this experience, FMCN created the Gulf of California Marine Endowment (GCME) in 2007 with the goal of contributing long-term conservation of the marine protected areas (MPAs) in the Gulf of California. The GCME currently has a capital of US$9.5 million and a fundraising target of US$30 million.
