Synthesising evidence on irrigation scheme performance in West Africa
2022
Redicker, Sarah | Dimova, Ralitza | Foster, Timothy
Emerging evidence and site-specific assessments suggest that irrigation infrastructure projects and reforms in West Africa have failed to achieve proposed targets. We evaluate this proposition by conducting a systematic review of 47 irrigation scheme assessments evaluating performances of 147 irrigation schemes. We find that 83% of the assessments identify the considered irrigation schemes as underperforming in terms of achieved benefits and/or maintenance over time. The observed problems are rooted in unclear project objectives, lack of post-project accountability, and failure to consider all stakeholders. Lessons from the past need to be taken on board to avoid unsuccessful investments in the future.
