Technical efficiency of irrigated rice systems: An empirical study in the Senegal River Valley

Abstract

This study examines the productive performance of irrigated rice systems in the Senegal River Valley (SRV). Employing a translog stochastic frontier model with simultaneous estimation, the research demonstrates that the use of improved seeds, fertilizers, modern capital, and part-time labor significantly enhances yields within a framework of increasing returns to scale. While the average technical efficiency score is 82.9% indicating a potential 17.1% productivity gain without additional inputs significant disparities exist: Large Irrigated Schemes (84.9%) and Private Irrigated Schemes (80.5%) notably outperform Village Irrigated Schemes (68.1%). Technical inefficiency is primarily mitigated by larger plot sizes, the practice of double cropping, and improved access to credit.These findings suggest prioritizing investments in the rehabilitation of VIS and promoting land consolidation to capitalize on economies of scale. Furthermore, strengthening agricultural credit mechanisms and securing water management to generalize annual double cropping are essential levers for closing the efficiency gap and achieving food sovereignty.
