As recognised by the CE Cooperation Strategy, climate change is expected to affect the region considerably in the near future, with a predicted alteration of precipitations leading to hectic variations in the discharge of rivers and negative effects on availability of water resources with potentially increasing users conflicts. Strategic documents in the countries involved in DEEPWATER call for groundwater recharge through MANAGED AQUIFER RECHARGE (MAR) schemes, a viable approach for collecting excess surface water and precipitation in periods characterized with water abundance, and storing it for dry times in underground aquifers. However, at a transnational CE level, implementation of MAR schemes that are successfully applied in other EU regions are yet to be deployed. DEEPWATER-CE aims at developing integrated environmental management capacities of responsible public actors of CE for a comprehensive transnational approach to plan and manage water resources and adoption of MAR schemes as a solution to climate change induced water scarcity. This is done with analysing the CE conditions for applicability of tailored MAR solutions, identify the CE areas of highest need through climatic scenarios and study the MAR feasibility in CE identified pilot sites, building on results of relevant previous FP7 and H2020 projects. After PP5 - State Water Holding 'Polish Waters' official withdrawal 7 Partners from 5 CE countries, relevant APs and decision makers representing competent public and private organisations will improve their capacity to apply a comprehensive approach to water planning and management that encompasses ecological, social, and economic objectives, considering the needs of cross-sectorial stakeholders and target groups that are involved since the project very start, building on existing knowledge and best practices and translating the pilot findings into ready-to-implement policy recommendations on MAR adoption through action plans.
