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 the Black Marsh of Saint-Coulban

Since 1984, the Hunting Federation of Ille-et-Vilaine Department has been rehabilitating a 550-hectare marshland that was heavily developed in the last century. Rehabilitation began with the replacement of corn crops by hay and pasture natural meadows via contractual agreement (with finacing) with the farmers. It continued with the restoration of a peat bog and a reed bed. In addition, due to the highly developed nature of the marsh and its drainage by a highly recalibrated and deepen watercourse, artificial water level management was also put in place to allow winter flooding. The project's objective is to improve the marsh to allow migratory waterbirds halting and to improve some of the marsh functionalities (carbon sequestration by peat and natural water purification). They have been achieved with regard to bird halting, but water level management is not currently optimised and will be reviewed to improve the hydrological functioning of the marsh.


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. […]
