The United Nations’ target for global ocean protection is 10% of the ocean in Marine Protected Areas (MPAs) by 2020. There has been remarkable progress in the last decade, and some organizations claim that 7% of the ocean is already protected and that we will exceed the 10% target by 2020.

This paper argues that current protection has been overestimated because it includes areas that are not yet protected, and that areas that allow significant extractive activities such as fishing should not “count” as protected. The authors state that currently only 3.6% of the ocean is in implemented MPAs, and only 2% is in implemented strongly or fully protected areas and that rigorous projections suggest that we will not achieve the 10% target in truly protected areas by 2020.

It is concluded that if the world is to achieve the United Nations’ target of 10% of the ocean protected by 2020, countries need to implement what has been committed, enact what has been suggested, and create new fully protected areas. The authors underline that strongly or fully protected areas are the only ones achieving the goal of protecting biodiversity; hence they should be the MPA of choice to achieve global ocean conservation targets.
