Description
Expected Outcome:
Project results are expected to contribute to all of the following expected outcomes:
- farmers have access to water supply from managed aquifer recharge systems and to appropriate business models to cope with longer and more intense periods of water scarcity due to climate change, while preserving the good status of ground water bodies;
- water ecosystems are healthier and more resilient to climate change, and water related ecosystem services are protected and strengthened, while water resilience of farming systems is increased;
- policy makers are provided with improved insights on mechanisms and instruments to improve the water resilience of the agricultural sector to cope with climate change effects.
Scope:
Droughts in the EU are increasing in frequency, magnitude and impact, and the affected area is expanding. Water storage systems can limit abstractions from surface waters and groundwater reducing the environmental footprint of agriculture and food systems, and bring the demand and supply of water better in balance, strengthening the resilience of EU agriculture.
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 [1].

Activities are expected to achieve TRL 4-5 by the end of the project – see General Annex B.

Destination & Scope
This destination will support the EU Commission priorities ‘Sustaining our quality of life: food security, water and nature’ and ‘A new plan for Europe’s sustainable prosperity and competitiveness’.
The implementation of the European Green Deal will continue to guide R&I in this destination. R&I actions under this destination will take forward the zero-pollution ambition, contributing to reach the 2030 targets for pollution reduction in air, water and soil, as stipulated in the zero-pollution action plan. The activities will help establishing a clean industry, contributing to the EU Clean Industrial Deal[1], and will aim to address, among others, pollutants of concern, including of emerging concern, also in view of the environmental objectives of the European Chemicals Industry Action Plan[2]. Destination ‘Clean environment and zero pollution’ will help substituting hazardous chemicals and bringing innovation on safe and sustainable by design chemicals to ensure protection of human health and the environment. It will also continue the work on PFAS, the “forever chemicals”, started in the same destination in WP2025. It will also support the implementation of the revised Ambient Air Quality Directive[3] and the Industrial and Livestock Rearing Emissions Directive[4].
This destination will support the zero-pollution ambition in the industrial bio-based and bioeconomy sectors. The principles of the new EU bioeconomy strategy, underpinned by the principles of the circular economy, will allow for the replication value chains with improved resource efficiency and environmental performances, also enabled by innovative approaches designed in the Strategy for European Life Sciences, the EU Startup and Scaleup Strategy and the upcoming Biotech Act.
Furthermore, R&I activities under this destination will underpin EU water legislation and the European Water Resilience Strategy[5] by addressing water quantity and quality issues in specific sectors as well as across broader water systems, supporting EU policies and international conventions. The destination will also support the Marine Strategy Framework Directive[6], particularly in its efforts to assess and mitigate the impacts of human activities on marine ecosystems such as contamination and underwater noise.
R&I actions under this destination will aim to underpin the conclusions from the Strategic Dialogue on EU Agriculture and the Vision for EU Agriculture and Food[7], and support the next reform of the CAP with scientific evidence.
R&I actions under this Destination will encourage international cooperation, in line with the global approach on R&I. The Destination supports unlocking the unique assets for research and innovation of the EU outermost regions, in line with the EU strategy for outermost regions[8].
Expected impact: Proposals for topics under this destination should set out a credible pathway to "achieve a clean environment, ensure water resilience, and enable the transformative change necessary to reduce air, water and soil pollution to levels no longer considered harmful to health and natural ecosystems, while respecting planetary boundaries". More specifically, they should contribute to one or several of the following expected impacts:
- Advancing scientific understanding and innovative solutions for identifying, preventing and mitigating pollution aim to effectively protect human health and safeguard the environment, preserving cleaner water and seas, healthier air and soil, and resilient forests.
- Innovative circular bio-based systems and biotechnologies are developed and made available to all stakeholders to progress towards the clean environment and zero-pollution ambition.
- Farmers and other actors in the food chain are empowered to make informed decisions and to apply novel strategies to prevent, reduce and remediate pollution from agriculture and the food system, contributing to the zero-pollution ambition.
- Effective solutions to remediate and decontaminate aquatic pollution are developed, made available and implemented contributing to reducing pollution to levels no longer considered harmful to the environment.
