IUCN, the International Union for Conservation of Nature, is the world's oldest and largest environmental network, with more than 1,000 government and NGO member organization, and almost 11,000 volunteer scientists in over 160 countries. IUCN’s Global Marine Programme (GMP) pioneers pragmatic solutions to marine environmental challenges. The Programme highlights science and technology for the sustainable management and conservation of marine ecosystems by connecting scientists and conservationists with decision-makers in governments and with private and public sector partners across its extensive network to develop policy, laws and best practices. Through its comprehensive network, GMP provides a convening power, connecting members and partners on both national and regional scales. IUCN’s recognized imprimatur serves to amplify leading voices in ocean conservation. GMP uses its strategic communication and outreach skills to advance science-based solutions, mobilize decision-makers, the media and raise public awareness on key marine issues from climate change and endangered species to fisheries and marine world heritage. In addition GMP works alongside IUCN’s World Commission on Protected Areas (WCPA) Marine to promote the establishment and effective management of a world-wide representative network of marine protected areas.
