Nature4Cities is a Horizon 2020 research project whose goal was to create a comprehensive reference platform for nature-based solutions. The platform offers technical solutions, methods and tools to empower urban planning decision making concerning nature-based solutions. The platform helps addressing the contemporary environmental, social and economic challenges faced by European cities.

Within the Nature4Cities project, Innova Integra created a customised version of the CITIZENS-SAY citizen collaboration platform that facilitates inclusive planning, development and use of nature-based solutions by bringing professional stakeholders and the citizens that may benefit from new nature-based solutions. The project began in 2017 and was successfully completed in 2021.
