Predicting recovery in acidified freshwaters by the year 2010, and beyond


From 04/2000 to 03/2003

Principal Investigator: Egbert Matzner
Staff: Christine Alewell, Elisabeth Herrmann, Annette Prechtel, Dorothea Wiesner
Grant: RECOVER 2010 Predicting recovery in acidified freshwaters beyond 2010

RECOVER:2010 is designed to assess the impact of current and future anthropogenic pressures on sensitive European freshwater ecosystems. Initially, it will evaluate the present extent of recovery of acidified freshwaters, and identify and quantify the dominant driving processes governing the timing and magnitude of recovery. Subsequently, the predictive capability of existing biogeochemical models such as MAGIC7 will be improved through enhanced process representation and the incorporation of linkages between hydrochemical changes and biological impacts. Pan-European application of the models to different ecosystem types, will evaluate the degree of compliance with respect to restoration of acidified waters by the year 2010, as specified under the Water Framework Directive. Similarly, agreed and proposed UN-ECE protocols on emissions control will be critically assessed, and economic costs and environmental benefits evaluated, with respect to the recovery of freshwaters. The project also aims to develop an end-user focus group linking research and policy, and so enhance the relevance of the project.
