Kurzfassung/Abstract
The Danube river basin covers more than 800,000 square kilometres – 10% of continental Europe – and extends into the territories of 19 countries. Seven of these countries (Austria, Bulgaria, Germany, Hungary, Romania, Serbia, Slovenia) were partners in the ‘Improving water quality in the Danube river and its tributaries by integrative floodplain management based on Ecosystem Services’ (IDES) Project. The IDES Project aimed to improve water quality in the Danube River and its tributaries.
The quality of life depends on the functionality of the ecosystems through the services they provide (provisioning, maintenance and regulation, and cultural). However, pressures from agriculture (changes in land use, excessive use of fertilisers and pesticides, and soil degradation) and other sectors (energy, transport and tourism) modified and degraded those ecosystems. Consequently, human activities had direct, negative impacts on these services.
Mapping and assessing the ecosystem services in the floodplains of the Danube river basin provided an overview of the current status and offered the basis for science based/informed decision-making. Although there are multiple methods to evaluate ecosystem services, there was no specific method available to evaluate ecosystem services on floodplains. The IDES Manual presents a new approach for ecosystem service-based integrative floodplain management, one which considers all relevant societal interests and objectives. Twenty-six ecosystem services which are typically provided by river-floodplain systems in the Danube river basin were selected from the three main groups of services, and evaluated. Factsheets for the indicator-based evaluation of ecosystem services were created as an easy-to-use tool for decision-makers in different sectors (water management, agriculture, energy, transport and tourism). Several visualisation methods were described and applied in five pilot areas in Austria, Hungary, Romania, Serbia and Slovenia. The different pilot areas were selected to represent different territorial and Summary practical challenges; for instance, conflicts with agriculture, forestry, flood prevention, navigation and fisheries.
The IDES approach was co-developed with local stakeholders through a series of knowledge sharing interactions that identified the most relevant ecosystem services, pressures and measures to reduce negative impacts. Fuzzy Cognitive Models, elaborated together with stakeholders, proved to be the most suitable tool to reflect the discussion among the stakeholders on how ecosystem services, pressures and measures to improve water quality are interlinked. The models were then used to draw conclusions and discuss the ideal and optimal scenarios for improving the situation. The optimal (more feasible and site-specific) scenarios rather than the ideal (where no pressure is exerted on ecosystems) scenarios were chosen to give a realistic chance of an actual implementation. Using nature-based solutions in the floodplains to reduce the nutrient load, implement flood mitigation, address climate change adaptation, or improve water quality can be a win-win solution for a more sustainable development. Collaboration between scientists and other stakeholders fostered the integration of optimal scenarios to improve water quality in the Danube river basin into national roadmaps and the Transnational Strategy.
Multiple scientific partners and stakeholders at different levels (national, regional and local) were brought together under the Project framework. Communication between scientists and decision-makers has been strengthened. The success of IDES is best represented by the agreement among stakeholders on a common approach for the evaluation of ecosystem services in the Danube river basin, and the setting of a common goal to achieve better water quality by implementing nature-based solutions. The integration of the ecosystem services concept into all relevant policies and its operationalisation using different tools (including the IDES Tool) are necessary steps towards reaching together environmental, social and economic goals.
