Their loss and/or degradation in the 20th century amounts to 73 per cent of marshes in Greece, 86 per cent of the most important wetlands in France, 60 per cent of wetlands in Spain and 15 per cent of lakes and marshes in Tunisia (MEDWET, 1996). The reasons for this have been the prevention of water-borne diseases, the development of agricultural land and the expansion of cities. Fundamental changes have occurred in our understanding of the functions and values of wetlands, and these have prompted many recent international efforts to protect and sustainably use the Mediterranean wetlands. Today, nearly 100 Mediterranean wetland sites have been listed as being of international importance under the Ramsar Convention. Since 1991, these efforts have been coordinated through MEDWET, a partnership between the European Commission, the Ramsar Bureau, the governments of France, Greece, Spain, Italy, Portugal and several non-governmental organizations. MEDWET is an initiative for concerted action, joint fund raising and mutual co-operation in wetland conservation policy. It adopts the ‘wise use’ imperative of the European Union, but also takes explicitly into account a number of factors considered to affect specifically the management of Mediterranean wetlands, namely: • poverty and economic inequality • pressure from population growth, immigration and mass tourism • social and cultural conflicts The Venice Declaration, detailing...
