Description: Das Projekt "Vorhersage der Erholung von angesaeuertem Suesswasser bis zum Jahr 2010 und darueber hinaus" wird vom Umweltbundesamt gefördert und von Universität Bayreuth, Bayreuther Institut für Terrestrische Ökosystemforschung, Lehrstuhl für Bodenökologie durchgeführt. Objective/Problems to be solved: RECOVER:2010 is designed to assess the impact of current and future anthropogenic pressures on sensitive European freshwater ecosystems. RECOVER:2010 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. This Pan-European assessment will use enhanced predictive models to 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. Scientific objectives and approach: Empirical data from different acidified European ecotypes will be evaluated to provide measures of time lags in response to changes in emissions of acidifying compounds, and indeed to separate out the different contributing processes. Regional controls on sulphur dynamics, and the role of nitrogen in the recovery process will be determined. Current conceptualisation of the recovery process has not considered potential interaction with natural variations such as climate induced impacts, and RECOVER:2010 aims to assess the magnitude and spatial extent of these confounding factors. Current dynamic modelling approaches will then be enhanced through improved process representation, and through the linking of hydrochemical changes to biological impacts and time lags in ecosystem recovery. An evaluation of Pan-European existing and proposed emission controls will then be undertaken to determine spatial and temporal patterns of response. Feedback from the modelling evaluation will be central to the development of strategies to optimise environmental benefit against economic cost. Similarly, the timing of mitigation measures such as the implementation of S and/or N emissions reduction, will greatly influence the expected recovery of both individual regions and Europe as a whole. These, previously un-addressed interactions, will be also explored within RECOVER:2010. Hence these are distinct scientific, methodological and policy challenges which interact within the concept of RECOVER:2010. Expected impacts: The development of sustainable options for emissions control reductions is required to balance economic, social and environmental constraints. RECOVER:2010 will specifically address such concerns, and the involvement of an end-user focus group comprising National and International Agencies, will ensure that the results of this project extend further than just the scientific domain.
