Coral reef conservation by means of the global network of Marine Protected Areas

that are theoretically protected against any illicit activities, less than 0.1 % are really free from all exploitation. The effectiveness of management methods varies between countries, but it is particularly low for the zones of high coral diversity like the Indo-Pacific region or the Caribbean. The aim of setting up Marine Protected Areas is to limit the impact of human activities. However, 85% of coral reefs situated within the MPAs are prey to local threats such as sedimentation, pollution, coastal development or overfishing, including in most centres of coral diversity.

It is now established that coral reef resilience (1) depends on functional organization, for example the presence of herbivorous fish and their predators. However, these populations are often characterized by migratory movements which expose juveniles and adults alike to the risk of fishing beyond the reserve boundaries. Some fish have territories of several square kilometres. Therefore it is not possible for reserves less than 12 km2 in surface area (as are 40% of MPAs) to provide enough protection for several key functional groups. A critical minimum size of about 10 km2 is necessary.

The criteria of size and isolation of MPAs as well as the distribution of coral reefs in the world, the creation of a network of MPAs, each of which would incorporate reserves of 10 km2, 15 or so kilometres between each other, would involve the designation of more than 2500 new MPAs. This would correspond to more optimal protection of 25 590 km2 of reefs, amounting to 5 % of the world's coral reefs, a figure far from the objectives declared at the 2002 world sustainable development summit which would require 20 to 30% of the major ecosystems to come under protection between now, in 2006, and 2012.
