The region of het Groene Hart in the Netherlands currently faces many issues, of which soil subsidence is the most urgent. The problems are mainly caused by the dairy industry, which covers 80% of the region. A fundamental change in land-use is therefore needed. In this paper first the Groene Hart region will be described and explored, after which the current issues will be presented. Next, different sustainable farming methods will be explored to find alternatives to the current landuse. Finally, natural building materials suitable to grow on peat soil will be described, which can be
used to design a circular, zero-impact farm.
