. The Cost of Policy Inaction: The case of not meeting the 2010 biodiversity target. Figure illustrates the relationships between different ecosystem sendees in a different way than figures and In diagram 1, the service levels in a natural ecosystem are depicted to be in some kind of balance, fitting the capability of the particular ecosystem. In the second diagram, the system has been converted to extensive use for food production, thereby decreasing the potential and actual service levels of the other provisioning (energy, freshwater), regulating (climate) and supporting services (soil protection). In Diagram3, representing an intensive food production system, the other services have been reduced to very low levels. 1 Natural Food. Energy Freshwater Freshwater ntensive Sonne: Ben lin Brink 2008). Figure The consequences for ecosystem sen'ice levels of' maximising foodproduction Next to these generalised characterizations of the functional relationships between biodiversity, ecosystem processes and ecosystem services a great amount of information is available in specific case studies. Before introducing a simple model, a few of these cases are reviewed. Very little work has been done so far on the quantification of the functional relationships between biodiversity features such as mean species abundance, species richness, extinction risks etc and specific ecosystem sendees. The above characterisations are based on the ecological textbooks and the mass of qualitative case material published through the MA (2005b). Together with the cases inserted in Boxes in this chapter a set of simplified functional relationships for groups of ecosystem services have been developed in the COPI project to allow a bridge between the calculated future changes in areas (per type of land use) with associated changes in total biodiversity (because of the different biodiversity levels per land use type), and the wide variety of monetization case studies and estimat
