The document summarizes a European Union Horizon 2020 topic on developing nature-based solutions to reduce hydro-meteorological risks like flooding and drought. It identifies key research institutes and networks involved in water management projects that would be well-suited to participate in proposals for this topic. Top institutes are in the Netherlands, Spain, UK, Germany, Italy, and Denmark. The proposals should develop, demonstrate, and deploy innovative ecosystem-based approaches to risk reduction in rural and natural areas like mountains and coasts.
