Abstract

Integrated Coastal Zone Management (ICZM) is related to a balance between economic, and natural system. The aim of this paper is to describe the possibilities to reach a more sustainable way to plan the social and economic development of a region using ICZM. Facing ICZM within a complex administrative region like Latium is not an easy task, because of the presence of deep (economic, natural, social, etc.) differences along the coastline: very long coastline (over 300 km) starting from Tuscany and arriving to Garigliano river (bordering with Campania). Along the coastline we can notice the presence of: wetlands and important natural preserved areas (coastal lakes in Pontina Plan, e.g.), former marshes, drained in the past centuries (Pontina Plan, Maccarese); archeological remains and historical monuments; touristic resorts; strongly urbanized areas, even for the presence of houses for tourist accommodation, the most utilized accommodation form with an high environmental and landscape impact; agricultural activities; fisheries; ports. On the other hand, using ICZM, we have necessity to face different levels of interpretation of coastal line (natural, environmental, economic, social, …) with very different skills needed. Furthermore, the coastline in not really a “Line” but a “strip” more or less large, including the so called hinterland (the territories bordering the coastline, with their economic activities, land use, urbanization, natural and protected areas, …) and a band of the see facing the coastline. For these reasons it is necessary to make a chose when you decide to face an analysis based on ICZM: face the whole problem with the involvement of many researcher with different skills and capacities or take only some aspects of the problem and deep them to discover weaknesses present in the management of coastline. This is true even if we want to intervene to solve problems: we can chose to face the problem of coast erosion if we consider this problem prominent, or we can chose to face the sea pollution, or we can look at social and economic problems related to environmental quality and the quality of life in the region.
