Most of the marine protected areas (MPAs) around the world, estimated to number about 5000, have been established both on an ad hoc basis and through systematic planning processes. The Convention on Biological Diversity (CBD) requires that Party states establish, by 2012, comprehensive, effectively managed, and ecologically representative national and regional systems of protected areas, and that there should be effective conservation of at least 10% of each of the world's ecological regions by 2010. Many countries have established their own national targets which provide an incentive for the introduction of a systematic conservation planning approach to the establishment of MPAs, and there are now many initiatives to develop ecologically representative MPA networks (UNEP-WCMC, 2008, p. i).
5 Jun 2018 - Managed marine protected areas are an effective tool in coastal ocean conservation. They are also ripe to be included in investment structures. The upsides for everyone may help push the protected area of the world’s seas from 2% to 30% by 2030.
