|Abstract:||The key objectives of the Land-Ocean Interactions in the Coastal Zone (LOICZ) core project of the International Biosphere-Geosphere Programme (IGBP) are to: - gain a better understanding of the global cycles of the key nutrient elements carbon (C), nitrogen (N) and phosphorus (P); - understand how the coastal zone affects material fluxes through biogeochemical processes; and -characterize the relationship of these fluxes to environmental change, including human intervention To achieve these objectives, the LOICZ programme of activities has two major thrusts. The first is the development of horizontal and, to a lesser extent, vertical material flux models and their dynamics from continental basins through regional seas to continental oceanic margins, based on our understanding of biogeochemical processes and data for coastal ecosystems and habitats and the human dimension. The second is the scaling of the material flux models to evaluate coastal changes at spatial scales to global levels and, eventually, across temporal scales. It is recognized that there is a large amount of existing and recorded data and work in progress around the world on coastal habitats at a variety of scales. LOICZ is developing the scientific networks to integrate the expertise and information at these levels in order to deliver science knowledge that addresses our regional and global goals. LaguNet is an example of such a scientific observational network studying the fluxes of nutrients and other contaminants from lagoon catchments to the near-coastal environment. The idea of developing a network of Italian researchers involved in the study of lagoons and coastal transitional ecosystems was developed during a workshop "Coastal and estuarine systems of the Mediterranean and Black Sea regions: carbon, nitrogen and phosphorous fluxes" organized in Athens (2-5 February 2001) by LOICZ with the support of UNEP and ELOISE. In the proceedings of the workshop is included a first series of estimates on the fluxes of nitrogen and phosphorus from selected transitional ecosystems of the Italian coast which contributed to filling an information gap on information on the Mediterranean region. In this monograph, LOICZ budgets around italian coast have been analysed.|
