Life Critical shows an innovative approach to adapting old city neighbourhoods to the effects of climate change. It addresses the problems that these neighbourhoods face by exploiting the potential of nearby parks for climate adaption. Crucial for this approach is the proactive involvement of citizens and co-ownership, because without their support the changes to the parks are difficult to realize. This is demonstrated in two cities: Wielwijk in Dordrecht and Greater Horton in Bradford. Seven other EU cities showed direct interest in this project, of which Ghent (B) and Bergen (N) will participate in the transferability action.
