In the context of the Post-2020 Global Biodiversity Framework, this report (and the briefing note) 1) articulates why we need a framework that works for cities; 2) reviews actions that cities are already taking in the realms of Conserve, Restore, and Thrive, based on the research of the NATURVATION project; and 3) makes the case that these actions should be acknowledged in the Framework and form the basis of any urban-focused commitment platform. Mobilisation of local and subnational stakeholders is critical to reaching the highest ambition of the Post-2020 Global Biodiversity Framework. Cities are already actively implementing nature-based solutions as our research findings demonstrate. But cities tend to take action in the context of specific kinds of parameters, and thus the Framework and commitment platforms need to appeal to this context.
