We examine the impacts of perceived landmine risk on the welfare of agricultural villagers more than two decades after the end of civil conflict in Cambodia, which lasted from 1970 to 1998, using Cambodian censuses. Using an instrumental variable approach, we find that the perceived risk of landmines has some long-lasting effects despite significant efforts toward demining. Perceived landmine risk is associated with lower crop productivity, higher crop diversity, and higher labor rates among children aged 5–14 years. However, we do not find any significant transition away from agricultural production due to perceived landmine risk or effects on school attendance among the 5–9-year cohort or on child marriage among the 13–14-year cohort.
