McGill Faculty Affiliate: Jon Unruh

Jon Unruh is an Associate Professor of Geography at McGill University. His research, applied, and policy work over the past 20 years has dealt with post-conflict land and property rights in the developing world, and the intersection of land tenure and environmental change. His past endeavors have focused on conflict resolution, land policy and law, restitution, legal pluralism, approaches to reconciling customary and formal tenure systems, and agriculture in postwar and peace-building scenarios. His experience includes work in Sudan, Liberia, Somalia, Mozambique, East Timor, Sierra Leone, Liberia, Zanzibar, Ethiopia, Uganda, Madagascar, and Colombia.
