Faced with the greater frequency and intensity of extreme weather phenomena due to climate change and also the growing number of crises and clashes due to exceptional circumstances that have an impact on communities and make them more fragile, local authorities are ramping up their actions. They are multiplying their efforts in a bid to adapt, bolster their ability to cope and also do things differently faced with the serious situations their regions but also residents and infrastructures are exposed to: drought, water shortages, repeated and prolonged heatwaves, massive wildfires, storms, flooding, soil and coastal erosion, the collapse of biodiversity, deterioration of the environment and ecosystems…

Faced with the increase in risks, schemes designed to help adjust are gradually being introduced to protect and develop new planning, construction and regional organisation methods that are more efficient and resilient with the support of expertise, more tried and tested techniques and technologies or ones that are newer and more sophisticated. Local authorities are also learning how to co-operate at local level to transform their adaptation to economic, environmental and social risks into regional projects and collective resilience strategies
