The great value of the resources and habitats of the coast, one of the most productive area of our planet, have caused an intense development of these zones. Human activity related to aquaculture, fishing, agriculture, industry, energy production, maritime transport, tourism, etc. submits the coast regions to a very strong pressure. The sustainable development of these areas requires approaches that reconcile the limits of natural resources and their ecosystems, with the interests of the society; and lead to the implementation of international planning policies supported by the European Union.
