Public support for urban climate adaptation policy through nature-based solutions in Prague

In this study, authors investigated perception of and economic preferences for adaptation to climate change through a choice experiment (preferences of a sample (n = 550) from Prague, Czech Republic, for a citywide policy which would increase the use of six commonly used NbS in public spaces and on public buildings across the city). Results showed that the NbS policy is widely supported by the public over the status quo and that this preference is mirrored in citizens’ concerns about climate change and the risks posed by heatwaves particularly. Species diversity matters in the portrayed scenarios, suggesting that (bio)diverse NbS generate additional public value over single species measures and that policy which targets biodiversity may gain support. Implementation of NbS in public spaces (e.g., street trees, rain gardens) is preferred over measures implemented on public buildings (green roofs and facades). Furthermore, adverse experiences with heatwaves has increased support for the policy.
