AbstractClimate change (CC) is a global problem bringing multiple different changes in different regions that exacerbate the conflict between landscape demands. Policy in EU and elsewhere are facing the huge challenge of CC by developing specific regulations and strategies (e.g., European climate law, RDP 2014–2020) generally shaped in the United Nations Frameworks Convention on Climate Change (UNFCCC). The “new EU strategy on adaptation to climate change” sets out how the EU can adapt to the unavoidable impacts of CC and become climate resilient by 2050. Unfortunately, the factual implementation of these policies remains critical. Most often there is a lack of science‐based decision support tools empowering regional and local levels to act toward climate resilience. Here we have produced a strong interdisciplinary research effort to support the implementation of the EU strategy on adaptation to CC by providing free web‐based Decision Support Systems having a strong focus on factual territories. Our Geospatial Decision Support System aims to support local authorities/communities, scientists, and other stakeholders in EU and more in detail in Italy in better understanding and implementing local adaptation to climate change by means of a “Climate Change Resilience” toolbox oriented to evaluate the climatic anomalies and thermal crop adaptation. Specifically, in this research, two implemented tools have been discussed: (i) tool on General climatic variation and (ii) tool on Crop thermal adaptation. These tools are demonstrated in two different case studies at both EU and national level. Such a toolbox has been produced in the framework of the LANDSUPPORT Horizon 2020 project (www.landsupport.eu).
