Nature-based re/development of neighborhoods worldwide

PHYSI helps decision makers to address critical urban sustainability challenges through nature-based solutions (NBS). We support people and organizations in developing and experimenting with NBS-enhanced scenarios to regenerate their neighborhoods. Through the Urban Nature Atlas, we provide a one stop shop to learn about best NBS practices worldwide and make the most of them where you live.

What NBS stands for

Nature-based solutions (NBS) use the natural properties of ecosystems. They have the potential to limit impacts of climate change, enhance biodiversity and improve environmental quality while contributing to economic activities and social well-being (Naturvation).

NBS hold significant promise in responding to contemporary social, economic and environmental challenges by delivering a wide range of goods and services. Yet there is a substantial gap between this promise and their uptake, which cannot be bridged by business-as-usual approaches.
