In 2014, UNEP’s Regional Seas Programme celebrated its 40th anniversary. We are reminded of how successful these 18 regional MEAs spanning seven continents have been at bringing nations and institutions together in responsible stewardship of their shared environment. Around the world, the Regional Seas have improved coastal zone management, reduced land-based pollution, protected priceless habitats, and perhaps most importantly demonstrated solidarity of purpose. Every one of the Regional Seas Programmes fulfills a unique role, by creating an essential link between local and global levels of action and between member countries and the international community.
