Climate change impacts are here and now. The impacts on people, prosperity and planet are already pervasive but unevenly distributed, as stated in the new EU Blueprint strategy (European Commission-EC, 2019). To reduce climate-related risks, the EC and the IPCC agree that transformational adaptation is essential. The TranformAr project aims to develop and demonstrate products and services to launch and accelerate large-scale and disruptive adaptive process for transformational adaptation in vulnerable regions and communities across Europe. The 6 TransformAr lighthouse demonstrators face a common challenge: water-related risks and impacts of climate change. Based on existing successful initiatives, the project will develop, test and demonstrate solutions and pathways, integrated in Innovation Packages, in 6 territories. Transformational pathways, including an integrated risk assessment approach are co-developed by means of 9 Transformational Adaptive Blocks. A set of 22 tested actionable adaptive solutions are tested and demonstrated, ranging from nature-based solutions, innovative technologies, financing, insurance and governance models, awareness and behavioral change solutions. The project team, led by the University of Antwerp, gathers 22 partners from 11 countries and a well-balanced mix of sectoral and adaptation experts (5 RTOs and 1 SME), paired with 6 territories (4 local authorities and 2 charities), 8 additional solutions providers and 1 EU water-related NPO specialized that will support to structure a European Community of practice. Massive resilience increase and acceleration of transformation adaptation will be fostered by clustering various investors, testing bankable solutions, and defining viable (non-)commercial exploitation strategy for the TransformAr solutions, products and services.
