The aim of the MRSEI-CLIMAQS project is to set up a network of partners to prepare a project in response to the "HORIZON-CL6-2024-FARM2FORK-02-7-two-stage: Minimising climate impact on aquaculture: mitigation and adaptation solutions for future climate regimes" call for projects, which is of the "Innovative Action" type. Two projects will be funded for an overall budget of 9 million euros, and we would like to request 4.5 million euros for our CLIMAQS proposal. The evaluation will take place in two stages, the first of which will be blind, with a submission date of February 22, 2024. For the second stage, the complete project must be submitted by September 17, 2024. The CLIMAQS consortium plans to deploy multiple solutions around 6 workpackages to address the challenges of aquaculture in the context of climate change. The workpackages include solutions for diversification (WP1), innovative aquaculture systems and IMTA (Integrated Multi-Trophic Aquaculture, WP2), genetic selection (WP3), species nutrition (WP4), environmental monitoring and risk prevention (WP5) and aquaculture spatial planning (WP6). The various solutions proposed by the project partners will be tested through the implementation of case studies, and evaluated in terms of circular economy, economic, social and environmental sustainability, notably through socio-economic assessments (SHS) and life-cycle analyses in a 7th workpackage (WP7). The consortium currently comprises 7 organizations from 5 different European countries, with the French partner acting as coordinator. The coordinating group, comprising two researchers and a project engineer, has already been involved in a number of European projects at various levels of responsibility. More generally, the partners already identified are currently collaborating or have already collaborated in several European projects. However, to test and evaluate certain solutions, the network has identified a lack of skills in socio-economics, sociology, sustainable development and spatial planning, which we are seeking to identify and involve in our European project as part of this proposal to set up a European network. CLIMAQS will be designed to contribute to the expectations of the targeted call (Expected outcomes) and to the broader objectives (Expected impacts) of Cluster 6's Destination "Fair, healthy and environment-friendly food systems from primary production to consumption". The consortium has already identified a number of scientific and technical spin-offs, as well as economic, social, public policy and public perception impacts. Target groups have been identified, including aquaculture businesses, associations of professionals, environmental monitoring agencies, local authorities, European and national political players, civil society and consumers, and the scientific community. Indicators to measure these benefits are planned. All of this will be developed and specified in the plan for disseminating, exploiting and communicating the project's results. Following an initial video conference meeting in May 2023, two further face-to-face meetings are planned, mainly to optimize relations between partners and workpackages, the budget, and finalize the writing of the project to be submitted in February 2024. Expenditure for these two events is the most significant (missions, room hire and catering), to which have been added the costs of proofreading documents by an English-speaking scientist and the production of iconographies.
