WELCOME to the European NWRM platform

The EU Directorate General Environment promotes the use of nature-based green infrastructure solutions (official website) and this is progressively included in a range of policies of which for water. A range of activities and related relevant information portals are also available on climate change (Climate Adapt), on biodiversity (BISE), on forest (FISE).

As detailed on DG Environment official webpage, "Natural Water Retention Measures (NWRM) support Green Infrastructure by contributing to integrated goals dealing with nature and biodiversity conservation and restoration, landscaping, etc."

The current platform gathers information on NWRM at EU level. NWRM are green infrastructures applied to the water sector, which permit to achieve and maintain healthy water ecosystems, and offer multiple benefits.
From this page you can find out more about NWRM definition, browse NWRM related concepts, look for individual NWRMs or select them by benefits, access the practical guide that will help you find your way to implement NWRM, or directly access the different products: synthesis documents, catalogue of measures, catalogue of case studies. For easy navigation, please consult the user's guide. If ,you would like to have an overview on what this website could bring you, you can Access all main documents and datasets

You can also join us on LinkedIn and access the NWRM community of practice gathered on our discussion forum, and you can submit a case study...

Restoration of a natural floodplain meadow in the Quintarets at Isle-Jourdain

The major bed of the Save River includes a vast complex of wet meadows directly upstream of the municipality of Isle Jourdain (Gers), located partly in a floodplain area. A water abstraction well is located downstream of this complex for the supply of drinking water to the municipality. In order to reduce the risk of diffuse pollution from catchment, restore wetland habitats and contribute to downstream flood prevention, a 13 hectare parcel, riparian of the Save, was bought by the local community (CCGT) and leased to a farmer with a special contract. The field was converted to permanent natural grassland, and detention basins were dug to increase the storage capacity of the floodplain and development of wet plants community. The technique used for sowing the meadow is the "hay flower", hay from adjacent wetlands harvested late to include a wide seed bank, and makes it possible to obtain a floral procession adapted to the conditions of the meadow. This project has enhanced the natural grassland complex in the major bed of the Save. The project must still be completed by the conversion of another adjacent parcel, still cultivated.


Natural Water Retention Measures are multi-functional measures that aim to protect water resources and address water-related challenges by restoring or maintaining ecosystems as well as natural features and characteristics of water bodies using natural means and processes. […]
