Many of the European and world's ecosystems undergo degradation of terrestrial, aquatic and transitional ecosystems with nMany of the European and world's ecosystems undergo degradation of terrestrial, aquatic and transitional ecosystems with negative impacts on biological diversity and people’s livelihoods. In this context, research actions are needed to ensure the protection and/or restoration of ecosystems and their biodiversity whilst meeting the socio-economic, political and cultural needs of current and future generations. By networking 34 funding agencies from 27 countries from Europe & other continents, BiodivRestore aims to promote coordinated international research on conservation and restoration of degraded ecosystems and their biodiversity, in all environments, including a focus on aquatic systems. It will strengthen research & research programmes coordination to support science-based evidence for the implementation of a relatively wide range of European and International policy initiatives and therefore act for better management, conservation and restoration of ecosystems and their biodiversity. This will notably be achieved by launching two calls (one co-funded by the European Commission) for proposals, promoting research collaboration across national borders & disciplines and by supporting dialogue & collaboration between academia & stakeholders, and stakeholder engagement in research projects in order to increase the impact of research on policy & practice. BiodivRestore will also contribute to networking, clustering and capacity building activities for the research community in the field and enhanced synergy coordination between RDI funding programmes (national, EU, International) in the relevant research fields. Lastly, BiodivRestore will contribute to reinforce the links between BiodivERsA and the WATER JPI, to enhance their collaboration for issues at the crossroad of water resources, aquatic ecosystems and biodiversity sustainable management.
