“Natural Water Retention Measures in Urban Environments” (NWRM) showcases how the WES (Water and Environment Support) project supports Mediterranean countries in adopting nature-based solutions to better manage water resources and build resilience to climate change. The video explains how NWRMs, such as rainwater harvesting, permeable surfaces, rain gardens, swales, detention basins and retention ponds, use natural processes to retain water, reduce runoff, improve stormwater quality, recharge groundwater, and mitigate floods and droughts in urban areas. Through technical assistance, policy guidance and capacity building, the WES project helps authorities and practitioners understand the benefits of these measures and integrate them into national and local water management frameworks. The video highlights the role of the EU in driving these efforts and calls for collective action to embrace NWRMs as cost-effective, sustainable solutions that protect water resources and create healthier, climate-resilient Mediterranean cities.
