8 Concluding remarks It is our feeling that European governments have been unjustifiably postponing the improvements and creation of new statistics to incorporate relevant economic exchange value quantifications of site-specific environmental services from ecosystems. The Spanish pilot experience taken from the scientific literature presents operational and reliable results that show the vast difference between conventional commercial income and real income (if environmental income is incorporated) that society and the landowner enjoy.
9 Concluding remarks Future CAP reform could introduce suitable incentives to improve biodiversity assets in European Union extensive and intensive agricultures (European Commission, 2005). The agreed action between private landowners and public administration will be better applied if economic quantification is developed on the basis of specific ecosystems. Thus, the European Farm Accountancy Data Network (FADN) could be modified and extended to incorporate the ecosystem perspective and not only family agricultural income, as is the case today.
10 Concluding remarks Demand values for environmental services must always be a useful tool for public policy action. Nevertheless, in preserving biodiversity the policy option could be taken to ignore social preferences, when the policy makers and society accept that a loss of income is tolerable, against the unknown benefit of mitigating the biodiversity loss rate.
