Constraints and Knowledge Gaps for Different Irrigation Systems in Nigeria

Irrigation systems in Nigeria take various forms and most are privately managed by individual farmers. This diversity reflects the farmers’ needs to minimize setup costs and maximize the returns from these systems. Thus, in order to design appropriate policies to support irrigation expansion in Nigeria, it is critical to understand how choices are made in the installation of different irrigation systems and the constraints faced in the process. This working paper provides a framework for comparing constraints of different irrigation systems and the associated knowledge gaps. Available empirical data indicates differences in constraints between types of irrigation systems, but a review of the literature highlights the need for empirical studies on the specifics of these differences.
