MARCONS aims to coordinate efforts for advancing marine conservation in Europe and adjacent regions in order to help close the gap between research and policy in the European marine environment and contiguous regions. Through scientific advice and engagement with policy makers and marine managers, we are aiming to develop novel frameworks and decision support tools to aid policy makers to optimize trade-offs (i) between conservation and resource use and (ii) between conservation costs and benefits. We are developing harmonised and integrated research outputs and develop new methods and tools for more effective marine conservation. These include methods for the assessment of cumulative human impacts, including impacts of climate change, and its integration into conservation planning. Our aim is promote conservation principles and disseminate results to stakeholders, policy makers, and the wider public, whilst developing resolution strategies to address conflicts in the use of marine space.
