Losing Ground: Targeting Agricultural Land Take by Enabling a Circular Economy in Construction

Abstract

Among the numerous causes of soil degradation, one of the most severe and difficult to reverse is land take. Land take results in the loss of valuable ecosystem services that negatively impact soil health, especially in agricultural areas. The main drivers of land take are increased provision of housing, schools, hospitals, industrial and commercial sites, transport networks and infrastructures, mines, quarries and waste dumpsites. Globally, the rate and scale of land take is increasing. Given the impact on soil ecosystem services such as the carbon, hydrological and nitrogen cycles, preventing agricultural land take is essential if the triple planetary ecological crises of climate change, biodiversity loss and pollution are to be addressed. Most countries use sustainable management techniques to limit land take by development projects. In this opinion paper, we argue that the circular economy concept could help to establish an alternative perspective on how to understand and address the agricultural land take problem. Law and policy need to foster a systemic transition to a circular economy throughout the entire construction sector’s multiple material life cycles if it is to significantly reduce land take. We use England as a case study to show how the UK government can revise and build on current policy to enable a transition to a more circular construction sector. The case study provides valuable lessons for other countries at a crossroad on land use policy on how fostering a circular construction economy can reduce land take and maintain agricultural soil’s ecological services.
