The overall objective of MeCCAM is to develop, implement and recommend climate mitigation and adaptation solutions and increase the resilience and sustainability in the fisheries sector. MeCCAM employs an integrated multi-actor approach to deliver relevant and feasible results to support the fishing industry and policymakers. The outputs include: decision support tools allowing fishers to mitigate and adapt to climate change; innovative fishing gears to improve selectivity, fuel efficiency, and minimise habitat damage; and an environmental impact management software to reduce carbon emissions, and other impacts across the value chain. The solutions will be designed and implemented within six case studies (CSs) which have been selected for their suitability to address a multitude of challenges posed by climate change. MeCCAM also builds adaptive capacity by delivering: climate-informed advice prototypes for CSs; mitigation and adaptation plans at the CS level, as well as general recommendations; CS-specific plans for commercial utilisation of emerging species; and a policy brief on how to improve governance for mitigation and adaptation in the sector. Project outputs will be evaluated for their environmental and socio-economic efficacy in close collaboration with stakeholders. MeCCAM´s evidence-based and demand-driven solutions have a high potential for transferability to various regions and contexts and will provide actors with tools and pathways to advance climate resilience. MeCCAM will, therefore, contribute to the European Green Deal, the Common Fisheries Policy, the European Biodiversity Strategy for 2030, the Farm to Fork Strategy, United Nation’s Sustainable Development Goals 12, 13 and 14, as well as the Ocean Decade challenges 2, 3, 4, and 6.
