Proposals should:

• extend, improve and customize managed aquifer recharge (MAR) techniques at farm, basin and catchment level, covering most representative EU agricultural contexts in view of climate change;
• develop a methodology to help assessing the most suitable location or situations to implement these MAR techniques and validate with a representative sample of case-study regions, taking into account for the differential impact of climate change;
• develop a user-friendly monitoring, reporting and verification system (MRV) to follow the impact on ground water quality and quantity, as well as associated water ecosystems and dependent terrestrial ecosystems;
• evaluate the potential impact and sustainability of managed aquifer recharge techniques in rural areas, including on the groundwater ecosystems, associated water ecosystems and dependent terrestrial ecosystems, and drinking water from a multi-objective approach, and its integration with evidence-based engineered and Nature-based Solutions to reduce runoff, soil erosion and improve landscape climatic resilience;
• calculate the cost-benefits of MAR techniques and propose different business models for the compensation or remuneration of individual farmers or land managers (payments schemes, nature, carbon or water credits, …) for hosting MAR initiatives;
• demonstrate the feasibility of these business models at local level (catchment, river basin, …) by at least 2 case studies in different pedoclimatic zones and evaluate the possible barriers for adoption by farmers or land managers;
• provide a framework of governance models that could fit the different local socio-economic, regulatory and pedo-climatic conditions.

The actions funded under this topic are relevant to the EU policies related to the EU Vision for Agriculture and Food, as well as to the European Water Resilience Strategy and the EU Climate Adaptation Strategy.

Proposals must implement the multi-actor approach and ensure adequate involvement of relevant stakeholders, including farmers, land managers, water governance bodies and local authorities.

Proposals are encouraged to build on the results of relevant projects funded under Horizon 2020 and Horizon Europe and ensure collaboration with relevant ongoing and forthcoming projects from the Mission Soil and the Mission Ocean & Waters.

Proposals should follow the Guidance document on managed aquifer recharge techniques of the CIS Working Group on Groundwater.
