> Marine protected areas (MPAs) are regarded as a key tool in combating overexploitation and species extinction in the oceans. Their purpose is to protect marine organisms and their habitats by prohibiting or regulating certain human activities. Their number has increased significantly in recent years, and yet in many places, success remains elusive, for all too often, the planned conservation measures are implemented and monitored half-heartedly or not at all.
> The vast majority of marine protected areas around the world are currently missing their conservation targets and failing to effectively protect local marine organisms and habitats. This lack of success has prompted experts to look more closely at the conditions that must be in place for ocean life to benefit from protected zones. The findings are clear: jointly developed conservation plans and a wealth of scientific knowledge, as well as funding, human resources and regular monitoring of outcomes, are needed in order to halt species decline in these marine regions.
