This report focuses on ways we can use land and ecosystem accounting techniques to describe and monitor the consequences of biodiversity loss in the coastal wetlands of the Mediterranean. These ecosystems are characterised by the close coupling of economic, social and ecological processes, and any accounting system has to represent how these key elements are linked and change over time. This report discusses the importance of estimating the ecological and social costs of maintaining these systems, and the problems surrounding providing monetary estimates of the services associated with wetlands. It also shows how individual wetland socio-ecological systems (SES) can be defined and mapped using the remotely sensed land cover information from Corine Land Cover.
