Coral reefs A wide range of donor-based and innovative or market-based funding sources can be used to enhance the management of coral reefs. Protected Areas Domestic government budgets are the single largest source of protected area funding in most countries. In the developing world, many protected areas rely on funding from international agencies and other foreign donors, including multilateral donors (e.g. European Union, World Bank, regional development banks, and Global Environment Fund) and bilateral donors (e.g. USA, Canada, Australia, New Zealand and European countries). Significant funding also comes from private sources, including business and philanthropic foundations as well as nongovernmental organizations and local communities.
