This report focuses on ways we can use land andecosystem accounting techniques to describe andmonitor the consequences of biodiversity loss inthe coastal wetlands of the Mediterranean. Theseecosystems are characterised by the close coupling ofeconomic, social and ecological processes, and anyaccounting system has to represent how these keyelements are linked and change over time. This reportdiscusses the importance of estimating the ecologicaland social costs of maintaining these systems, and theproblems surrounding providing monetary estimatesof the services associated with wetlands. It also showshow individual wetland socio-ecological systems (SES)can be defined and mapped using the remotely sensedland cover information from Corine Land Cover.
