In cities of the Global South, access to land is a pressing concern. Typically neither states nor markets provide suitable land for all users, especially low-income households. In the context of urban growth and inequality, acute competition for land and the regulatory failures of states often result in conflict, which is sometimes violent, affecting urban authorities and residents. Conflicts are often mentioned in analyses of urban land, but rarely examined in depth. This paper develops a framework for land conflict analysis, drawing on relevant literature and the papers in this special issue. In order to explore the drivers, dynamics and outcomes of urban land conflicts, diverse disciplinary perspectives are discussed, including environmental security, political ecology, legal anthropology, land governance, conflict analysis and management, and urban conflict and violence. The papers focus on conflicts in the peri-urban areas of Xalapa, Mexico, and Juba, South Sudan, and during informal settlement upgrading in eThekwini (Durban), South Africa, and Nairobi. A second paper on South Africa examines how current tenure law reflects the characteristics and outcomes of previous conflicts. We suggest that an analytical framework needs, first, to consider definitional categories, including the material and emotional dimensions of access to land, conflict and violence, and tenure. Second, it needs to identify and examine the interests and behaviour of the many actors involved in urban land conflicts. And third, it needs to analyse the interactions and relationships between those involved at different levels, from the individual/household, through the local to the citywide, national and international.
