The underappreciated value of brownfield sites: motivations and challenges associated with maintaining biodiversity

Protection and mitigation of biodiversity are essential within land-use planning; highlighted by the increased importance of nature during the global pandemic and the fight against climate change. Currently, the character of both the land and decision-makers can influence the weight biodiversity is ascribed within planning processes. Through analysis of semi-structured interviews, with various actors within the Northamptonshire planning system, this research explored the opportunities and challenges around promoting biodiversity across brownfield sites; the motivations for conservation by different planning actors; and what this means for the future of urban habitats on previously developed land. This research found that brownfield sites continue to be undervalued for their biodiversity potential, predominantly due to the downplaying of ecological expertise in decision-making. With England’s proposed planning reforms, this paper argues that tensions between brownfield redevelopment and biodiversity conservation stand to be further exacerbated as the government intends to “scythe through red tape” (Johnson).
