The URWAN NbS Catalogue

A comprehensive catalogue of Nature-based Solutions (NbS) focused on sustainable water management and urban greening. The catalogue provides a detailed overview of innovative and replicable solutions that enhance water resilience, promote urban biodiversity, and improve the quality of life in cities and towns.

Organised into two main categories – WATER SNOB NbS and WATER SMART NbS – the catalogue explores how Nature-Positive Solutions can mitigate the effects of climate change, reduce runoff, and support circular water use, particularly in dense or vulnerable urban environments.

Each solution is presented with technical features, environmental benefits, and practical examples of integration in different urban contexts, from small villages to metropolitan areas.
