Developing methods to assess the presence, functions and sensitivity of groundwater ecosystems

investigación innovación I+D+i desarrollo tecnológico europeo. HORIZON Research and Innovation Actions Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: the knowledge of existing groundwater ecosystems [1] is improved, supporting policymakers and technical experts in assessments of their presence, functions and condition or status, and their role for climate change mitigation; society benefits from enhanced knowledge and awareness of pollution and overexploitation risks to groundwater ecosystems and the ecosystem services provided by them, including of possible implications for other related ecosystems (associated aquatic and dependent terrestrial ecosystems) and for human health as well as for food and water security, disaster risk reduction and resilience building; the EU water polices are supported with new scientific evidence and public authorities are better equipped for setting effective measures for the protection of groundwater biodiversity and their possible links to groundwater-dependent ecosystems. Scope: The European Environment Agency (EEA)’s report on Europe's state of water (2024) [2] highlighted that 77% of groundwater, which supplies two thirds of the EU's drinking water, is in good chemical status.
