Assessment of Irrigation Scheme Management and Operation in the Hadejia Valley, Jigawa State

This study assesses the management and operational performance of smallholder irrigation schemes in the Hadejia Valley, Jigawa State, North West Nigeria. The Hadejia-Jama'are floodplain irrigation systems represent one of Nigeria's most ecologically important and agriculturally productive irrigation environments, supporting intensive dry season farming of rice, vegetables, and wheat. However, scheme management challenges including water distribution inequity, infrastructure deterioration, and weak water user association governance have constrained productivity and sustainability. This study uses a mixed-method assessment design, combining physical inspection of irrigation infrastructure on 15 scheme sites in Hadejia, Kafin-Hausa, and Kaugama local government areas with surveys of 120 scheme participants and 20 water user association committee members. Management performance is assessed using water distribution equity index, infrastructure condition scores, maintenance contribution rates, and conflict frequency indicators. Findings reveal that water distribution is significantly unequal, with head-end farmers receiving 2.3 times more water than tail-end farmers as measured by plot moisture indicators. Infrastructure condition is deteriorating on 58 percent of main canal sections. Water user association financial management is weak, with average maintenance fund utilisation rates of only 34 percent. The study concludes that scheme management deficiencies are constraining irrigation productivity in the Hadejia Valley. It recommends water user association capacity building, infrastructure rehabilitation, and demand-based water distribution systems.
