Since the field of Urban Political Ecology (UPE) emerged in the 1990s, it has focused on unsettling traditional understandings of the 'city' as an ontological entity separate from 'nature' or 'the environment'. This volume seeks to turn UPE's critical energies towards a politically engaging debate over what role extensive urbanization processes can and should play in addressing socio-environmental equality in the context of climate change. The collection brings together theoretical discussions and rigorous empirical analysis by key scholars spanning three generations, in order to move UPE squarely into current debates about urbanization and climate change. The editors put forth an integrated UPE agenda that is enriched, not split, by the expansion of the scope of its inquiry and well-suited to address contemporary environmental issues in theory and practice.
