Denmark opens first fast-track wetland area in Gamtofte near Assens

Denmark’s first fast-track wetland area has officially opened in Gamtofte near Assens. Three hectares of former agricultural land at Brahesborg Estate have been designated to remain permanently wet. Peter Cederfeld, the estate owner, emphasizes that this initiative will help bind nitrogen and fulfill commitments made by the agricultural sector to reduce emissions.

Traditionally, converting farmland to wetland has been a lengthy process, often requiring landowners to obtain replacement land for larger areas. However, municipalities have now streamlined this process for smaller plots. Jannik Seslef, project manager at Assens Municipality’s Environment and Nature department, explains that the fast-track approach allows for simple agreements with farmers regarding compensation for the land, expediting the conversion to wetland.

Wetlands play a vital role in decreasing the nitrogen and phosphorus runoff into Danish coastal waters, fjords, and lakes. In the newly established wetland, a previously drained area has been excavated to create a pond, with a formerly piped stream now restored to flow at the surface.

While the shift to smaller wetland areas may reduce the total nitrogen absorption from agriculture, the shorter processing times are expected to encourage more landowners to convert their land. Seslef points out, “Many small streams can make a big river,” suggesting that multiple small projects could yield similar benefits to a singular large initiative, but achieved more quickly.

Currently, three hectares from Brahesborg Estate have been allocated for wetland use, but Cederfeld notes that further areas may be explored for similar projects, pending suitable conditions for natural drainage. The excavated pond is intended to capture nitrogen from surrounding agricultural land.
