Citizens in urban areas face increased stress from extreme rainfall and heat. Dynamic rainwater buffers in blue-green roof systems can this stress. Pouring rain is collected, and the vegetation produces oxygen for the city. RESILIO will realize 8.000 m2 of smart blue-green roof systems on social housing complexes in 5 Amsterdam neighborhoods and an additional 2.000 m2 for private house owners, subsidized by a grant scheme of the City of Amsterdam. The goal of the Amsterdam Agreement Smart Blue-Green Rooftops is to create partnerships with other international cities in order to actively learn from each other and achieve sustainable collaboration. The aim of the Smart Blue-Green Rooftops agreement is to exchange and share knowledge on smart dynamic micro-level water management in cities and improve and strengthen the governance of innovative climate-adaptive blue-green infrastructure solutions.
