The International Union for Conservation of Nature (IUCN) defines Nature-Based Solutions (NBSs) as actions that protect, manage, and restore ecosystems to address societal challenges like climate change, while benefiting both biodiversity and human wellbeing. In the Aa of Weerijs catchment, where historic engineering drained excess water, emerging water shortages now call for new NBSs aimed at retaining water. Projects such as Co-adapt and Pro-Water have identified and mapped various NBS options, including installing small natural barriers in streams to slow water flow, reduce erosion, and enhance infiltration. These solutions are modelled and targeted to specific locations to improve climate adaptation strategies in the region.
