This article reports on the potential macroeconomic benefits of peace stemming from a reduction in farmer-pastoralist violence in four Middle Belt states of Nigeria (Benue, Kaduna, Nasarawa, and Plateau). Farmers and pastoralists routinely clash over access to farmland, grazing areas, stock routes, and water points for both animals and households. Farmer-pastoralist violence in these states is a relatively low-intensity form of conflict, but it is regionally widespread and chronic, and its incidence is arguably increasing. Using estimates of potential income benefits of peace at the household-level derived from a related study, we herein derive macroeconomic benefits via an input-output model of the Nigerian economy. We estimate these benefits to amount to around 2.8 percent of the nominal Nigerian GDP (or around 0.8 percent of the total Nigerian GDP, inclusive of the informal sector), representing a major macroeconomic opportunity. We break out these benefits by sector, showing that the sectors that stand to gain most from peace are the crop production, food and beverage, livestock, and chemical and petroleum industries.
