The acceptance of density: Conflicts of public and private interests in public debate on urban densification

Urban densification is crucial for sustainable urban growth. Yet, its implementation often leads to local conflicts. To understand the interplay between private and public interests, we analysed media reports on densification policies and projects in Switzerland from 2009 and 2019, a period when Switzerland revised its Spatial Planning Act, limiting land take and promoting densification. Our results reveal a disconnect between private and public interests. Residents and other established stakeholders tend to dominate the public debate. Arguments in the face of impending building often reflect conflicting social values related to distributive justice, such as rising housing costs, loss of identity of place, and erosion of social cohesion. NIMBYism, the “Not In My Backyard” phenomenon, is insufficient to explain criticism or the rejection of urban densification measures. Other factors, such as ecological concerns, have gained impact. Moreover, our study highlights that the Swiss direct democratic instrument of popular initiatives tends to stimulate public debate and, thereby, has the potential to better bridge public interests with the effects of densification policies on residents and communities.
