The emergence of food systems on a global scale transformed Dutch food regions into mono-functional production landscapes. It’s a crisis that manifests itself on multiple layers within our society, resulting in cultural fragmentation, environmental degradation and an undermining of regional autonomy. These urgent challenges call for new, adaptive and holistic approaches that ensure the protection and development of cultural- and environmental values, whilst ensuring profitable livelihoods for farmers. With their new role as agro-architects, landscape architects must have a leading role in the design of these sustainable food systems. Permanent Polder Food shows how design can be a means to transform the iconic Dutch food region Haarlemmermeer into a sustainable food system that is able to reject the conventional food landscape.
