Urban Planning for Climate Change: A Toolkit of Actions for an Integrated Strategy of Adaptation to Heavy Rains, River Floods, and Sea Level Rise

Cities and urban systems are the places most responsible for climate change, but at the same time they are the places where its effects are felt the most. A state-of-the-art analysis showed that Ecological-Environmental, Settlement, and Infrastructure and Service Systems are the components of cities most exposed to risk phenomena. Therefore, it is important to identify site-specific actions aimed at enhancing ecosystem services and building hierarchical ecological networks (green and blue infrastructures), according to an Ecosystem-based Approach (EbA). In this regard, the contribution presents the results of a research work on the theme of multi-risks connected to climate change, referring to heavy rains and river flood phenomena and sea level rise and proposes a systematisation of international best practices in the field of the Ecosystem-based Approach (EbA). Each best practice analysed is traced back to the three urban resilience macro-strategies of "defence", "adaptation", and "relocation/de-anthropisation", already conceptualised by the authors during their joint research activity. The aim is to outline a synthetic toolkit of site-specific design actions, exportable to other contexts, intended as a tool to support the innovation of urban planning tools at the local level.
