The construction of resilient and climate-neutral cities requires a shift in territorial management models to make them more sustainable and efficient. In West Brianza, urbanisation, fragmentation of natural areas and artificialisation of watercourses contribute to increase the exposure to CC risks. In order to strengthen the response capacity to the identified climate criticalities, four municipalities and a regional park authority have elaborated a Climate Transition Strategy able to provide a determined approach based on a shared vision of the territory.
