4th EbA Knowledge Day – organized by the Secretariat of CBD, GIZ and IUCN at the Rio Conventions Pavilion of CBD COP 14 – convened under the overall theme of ‘Biodiversity conservation and infrastructure development.’ The event included input presentations, panel discussions and a market place showcasing practical examples of nature-based solutions and possibilities how to better align these to engineering-based solutions for disaster and climate resilience. Participants learnt from current approaches, opportunities and challenges for aligning biodiversity conservation with infrastructure development in the context of climate change adaptation and disaster risk reduction both at policy and implementation level. The event was organized in collaboration with the Friends of Ecosystem-based Adaptation (FEBA) and Partnership for Environment and Disaster Risk Reduction (PEDRR) networks.
