Dr. McDougal has produced an insightful work that usefully challenges a number of disciplinary and conceptual boundaries. The empirical work undergirds the thesis that the economics of transport and the social structure of trade networks jointly determine the degree to which rural-based conflict entrepreneurs can or even wish to prey on urban areas. The main finding is that rural-urban conflict frontiers can be surprisingly supple, or rigid. Many scholars, practitioners, and policymakers will find this book an enriching read to help them think afresh about the political economy of violent conflict. The form and function of armed conflict is changing in the twenty-first century. So too are explanations of how wars start, why they endure, and what makes them end. Topher McDougal is in the vanguard of a new generation of economists committed to explaining the drivers of these so-called new wars. In The Political Economy of Rural-Urban Conflict, McDougal takes readers beyond the greed and grievance debates that dominated the 1990s and 2000s. In his rivetting new book he explains how violent predation in settings as diverse as West Africa and South Asia are a function of trade networks at the core and periphery of city systems. This is essential reading for scholars and practitioners alike. Robert Muggah, Co-founder of the Igarape Institute and SecDev Foundation
