Summary
This Project realized a combination of three natural water retention measures: the restoration of meadows and pastures (A1) as well as a large floodplain (N3). Furthermore reduced tillage (A7) was introduced to the area. The location of the measures was in north-west Germany within the river basin district Weser (DE4000). They were directed at national policy contexts, namely the Lower Saxony otter protection program and the Lower Saxony wetlands protection program, although they also mitigate impacts identified by the WFD. As mentioned above, the measures also served the creation of large scale floodplains. As result a wide variety of stakeholders were involved in the implementation, ranging from nature conservation agencies and water managers to local farmers. Therefore, different parts of the measures could be financed by different sources.
Apart from the main objectives of the project, it was also an important success in terms of cooperation of different stakeholders.

Lessons, risks, implications...
Key lessons
A continuous and open discussion between all involved groups led to a high acceptance of the overall process. It was a key lesson of this measure that cooperation between different sectors (flood protection, nature conservation etc.) as well as different stakeholder groups (government agencies, NGO†™s) are able to cooperate in effective networks, when a consistency of goals is given.

Landacquisition for the implementation of NWRMs was paid by the State of Lower Saxony.
Other measure were financed from different sources due to the various goals. NWRM unrelated constructions of dykes and technical facilities were paid from water management sources, whereas reconstructions of roads were paid by rural development funds. The cost for a specially prepared trail with nature information were covered by European funds. |

Willing stakeholders a positive public perception were the major enabling factors. A continuous and open discussion between all involved groups led to a high acceptance of the overall process. The availability of financial resources and cooperation between all stakeholders led to a smooth implementation of all measures.
