ECONOMIC VALUES OF DANUBE FLOODPLAINS

The Danube floodplains are shared by several countries and provide a c omplex ecosystem with various habitats or biotopes. Three of them have been selected, forests, grasslands and wetlands, which produce servic es of value to society. Examples of the ecosystem's services are water purification, biodiversity, flood control, wind protection and food s upply. In order to make appropriate estimates of these services, ecosy stem models are needed to describe how these services are produced and how they are linked to the economies of the countries concerned. Such models are not currently available. Therefore, this study makes rough calculations of values by transferring results obtained in other stud ies to the Danube floodplains. The services subjected to valuation are provision of input resources, recreation and nutrient purification. T he estimated total annual value of the existing Danube floodplains amo unts to ECU 374/ha. The total annual value of the entire actual area o f Danube floodplains corresponds to ECU 650 million per year. Approxim ately two-thirds of this value is obtained in Romania. The value of th e land as a nutrient sink accounts for about one-half of the total val ue. It should be noted that the calculations are based on several simp lified assumptions and the results must therefore be interpreted with caution. (C) 1995 Academic Press Limited
