Relief organizations and analysts of complex humanitarian emergencies recognized the essential linkages between war and hunger in the 1980s, building on the lessons learned from the famines in Sudan and Ethiopia. How can international donors and nongovernmental organizations address humanitarian suffering without exacerbating conflict? Mark Duffield’s latest book, Global Governance and the New Wars: The Merging of Development and Security, examines this question and makes a significant contribution to our understanding of the political economy of war and humanitarianism. Duffield provides a systematic framework that highlights the relationship between the emerging networks of globalization and liberal order and the “new wars” in the developing world. He builds on earlier literature that examined the conflict-producing potential of relief and the economic motivations of insurgents and broadens the research agenda to analyze how international economic structures provide opportunities to increase conflict.
