In the global South, urban infrastructures and environments are marked by significant heterogeneity and the presence of multiple overlapping systems, configurations and actor networks that keep the city working – water flows, electricity is available, and waste is collected. This occurs in the face of what has been traditionally characterized as failed or incomplete infrastructures and the presence of governance practices that often deviate from formalized norms and policies. However, increasingly academics are arguing that such heterogeneity represents not failure but spaces of possibility and transition. This introduction lays out some of the theoretical underpinnings and conceptual ideas that frame urban environmental and infrastructural governance in the everyday. We then outline how the contributions of this Special Issue (SI) reveal the contested, negotiated, and situated nature of everyday urban governance and the multiple ways that politics become spatialized and power shapes contemporary cities, urban environments, and infrastructures. The SI brings together an interdisciplinary and diverse range of contributions focusing on case studies in secondary and metropolitan cities in India, Tanzania, Malawi, Kenya and Guinea-Bissau, and Brazil. Read together, the papers in this issue contribute to four primary debates and discussions in urban studies and social science studies of the urban environment. These include responding to noted absences in studies of urban political ecologies, contributing to new understandings of the urban political, focusing on the practices that produce political subjectivity and render groups governable, and highlighting everyday spaces of possibility for a more equitable urban future.
