A unique project has been realized within the management area of the Noorderzijlvest water board in the Netherlands: an area of more than 1,700 hectares has been turned into a wetland with room for nature and agriculture, as well as more room for water. This space for water is necessary to be able to absorb the rise in water levels as a result of climate change.

De Onlanden is one of the first climate buffers in the Netherlands, next to the city of Groningen. Nature can develop in this climate buffer and the plot structure outside the climate buffer is improved. By seeking the combination of the three interests of agriculture, nature and safety, a unique area has been created with, among other things, beautiful nature, large water valleys and recreational facilities. The plans for the Onlanden were drawn up in collaboration with the residents of the area.
