The New Delivery Model established in Regulation EU 2115/2021 entails significant changes to Common Agricultural Policy (CAP) governance with the introduction of Strategic Plans and new monitoring, review and evaluation requirements. The CAP is expected to contribute significantly to the Green Deal’s ambitions, securing the achievement of sustainability and resilience goals for the EU’s Agri-food systems. Innovative governance models are essential to enable result-based policymaking to deliver the best policy pathways to facilitate the green transition. Tools4CAP will (1) support the implementation of National Strategic Plans 2023-2027, and (2) lay the foundations for sound preparation of Post-2027 Strategic Plans. Accordingly, Tools4CAP establishes a flexible and participatory Coordination & Support Action designed to boost learning, exchange processes, and adoption of innovative solutions and good practices for the design, monitoring and evaluation of CAP Strategic Plans. Tools4CAP’s methods and tools will cover three key areas: (1) quantitative modelling tools for ex-ante and ex-post evaluations, (2) participatory and multi-governance decision tools, and (3) novel data and monitoring solutions. The project will deliver a comprehensive inventory of methods and tools used in the 27 Member States, methodological guidelines on innovative solutions and a Handbook of good practices. Results will be integrated in a Capacity Building Toolkit, designed to enhance science-policy interfaces. Tools4CAP utilises a Stakeholder Engagement Platform to boost bottom-up adaptation of innovative methods and tools. It will establish a Replication Lab to demonstrate their use in 10 Member States and to promote their uptake across the EU-27. The project will also set up a Capacity Building Hub to help end-users (ministries, management authorities, paying agencies, other stakeholders) reinforce their capacity to use innovative tools, including models used by the European Commission.
