While early attempts at land titling in Africa were often unsuccessful, the need to secure land rights has kindled renewed interest, in view of increased demand for land, a range of individual and communal rights available under new laws, and reduced costs from combining information technology with participatory methods. We used a difference-in-difference approach to assess the effects of a low-cost land registration program in Ethiopia, which covered some 20 million plots over five years, on investment. Despite policy constraints, the program increased land-related investment and yielded benefits significantly above the cost of implementation.
