‘Highways and Hierarchies: Ethnographies of Mobility from the Himalaya to the Indian Ocean’ explores the contemporary proliferation of roads in South Asia and the Tibet-Himalaya region, showing how new infrastructures simultaneously create fresh connections and reinforce existing inequalities. Bringing together ethnographic studies on the social politics of road development and new mobilities in twenty-first-century Asia, this edited collection demonstrates that while new roads generate new forms of hierarchy, older forms of hierarchy are remade and re-established in creative and surprising new ways. Focused on South Asia but speaking to more global phenomena, the chapters collectively reveal how road planning, construction and usage routinely yield a simultaneous reinforcement and disruption of social, political and economic relations.
