Cities are facing growing challenges from climate change—like floods and droughts—as well as from urbanization, such as heat, air pollution, and water pollution. These pressures affect both people’s quality of life and urban biodiversity.

To address this, cities are exploring nature-based solutions, which use natural processes to solve multiple problems at once. One example is floodable parks—green spaces that can temporarily store rainwater during heavy storms while still serving as recreational areas. These parks help reduce flood risks, cool cities, and support wildlife, making them valuable for both people and the environment.

However, floodable parks are still relatively new, and more research is needed to understand their full potential. This project will study such parks at different stages of development in six European cities. It will focus on their environmental and social benefits, especially biodiversity, and involve both experts and citizens to ensure practical and lasting impact.
