Institutional Change, Incentive Effects, and Choice of Technology in Sudan's Irrigated Subsector: A Model of the Rahad Scheme

摘要

Sudan's irrigated subsector is the largest and among the most modern in Sub-Saharan Africa. A linear programming model of an average farm in the Rahad scheme is used to analyze the implications of technological and institutional change for cropping patterns, farm income, and demand for imported inputs. A base run and several alternative scenarios test how tenant farmers would react to a number of incentives and constraints.
