The international online expert workshop "Fostering applied research on the synergies between biodiversity and climate" organised by the Federal Agency for Nature Conservation (BfN) on 8 and 9 June 2022 brought together around 30 leading scientists to exchange knowledge and perspectives on this topic, highlight good practice application examples, and identify existing gaps to prioritise future research. A particular focus was on exploring the potential of nature-based solutions (NbS) and ecosystem-based approaches to adaptation and mitigation to deliver multiple environmental, social and economic benefits. The second focus was on how applied research - in particular research using transdisciplinary and participatory approaches - can help in unlocking this potential.
