What happens when we bring questions of power, territory, infrastructure, and ecological transformation into the same conversation? In this bonus episode of the Cities and Geopolitics miniseries, Nitin Bathla is joined by Malini Ranganathan and Garrett Graddy-Lovelace to explore the emerging field of geopolitical ecology. Moving beyond conventional understandings of geopolitics as a matter of states, borders, and great-power competition, the conversation examines how ecological processes, environmental governance, agrarian transformations, and everyday struggles over land, water, energy, and food have become central to contemporary geopolitical contestations. Drawing on examples ranging from agricultural frontiers and resource extraction to environmental justice movements, the discussion explores how geopolitical projects are materialised through ecological relations and how ecological crises, in turn, reshape political orders across scales. The episode reflects on the growing entanglement of environmental change, security, infrastructure, and global inequality, while considering what a geopolitical ecology perspective can contribute to understanding a rapidly urbanising and warming planet consumed by wars and blockades. The speakers discuss the intellectual origins of geopolitical ecology, its relationship to political ecology and critical geopolitics, and its potential to illuminate emerging struggles over territory, sovereignty, and planetary futures in the twenty-first century.
