Engaging the Polycrisis after Dark
To what extent does the current polycrisis intensify in urban settings during nighttime hours? Night lives are already characterized by precarity, urban inequalities, deeply seeded health and wellbeing concerns and a life ‘in the shadows’. In this Polycrisis series episode, Michele Acuto, Andreina Seijas and Alessio Kolioulis take us on a “walking roundtable”, recorded on the road after dark in London. The speakers discuss how nighttime perspectives shape how we encounter the urban polycrisis. They reflect on how night studies, and practice, prompt embedded thinking on the intersections of urban health, climate, economics and conflict with the experiences of dwelling, living and working in the city after dark. Crisis talk is being challenged through night talk, while the everyday dimensions of polycrisis are being considered, as they unfold in the mundanities of the night. The talk encourages us to engage with this world of urban research and practice by mixing a scholarly discussion, an insight into the urban challenges of a global city after dark, and a consideration of current solutions to improving nightlife inclusively, while taking us out on the streets of London after midnight.
