ClimaResponse aims to enhance sub-national public authority capacities to efficiently plan and implement climate change adaptation (CCA) and disaster risk reduction (DRR) strategies, which we refer to as climate resilience (CR). Climate change is projected to increase the severity and frequency of extreme weather events and their manyfold impacts within the BSR. However, many local authorities lack coordinated, longerterm procedures and processes to increase their preparedness and mitigate these risks. To overcome these documented challenges that sub-national authorities face, ClimaResponse will co-create and pilot social and technological innovations that will be integrated into a step-wise model for CR planning and implementation within a digital platform. The platform builds on existing resources and structures within the consortium, the BSR as well as the EU, but brings to local authorities (LAs) the level of detail in guidance and examples that make the uptake of innovations more feasible. The innovations are evidence based and complement are situated along the different phases of CCA and DRR (planning/implementation/evaluation) and are relevant to risk mitigation, preparedness and recovery. The digital platform content will be piloted and tested within the consortium as well as with external LAs throughout the BSR. The platform will be embedded into the work of multiplier organisations such as regional, national and a macro-regional network of LAs.
