Assessment of Irrigation Schemes in Ghana: Current Challenges, Emerging Opportunities, and Future Pathways

open access: yesApplied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Irrigation schemes are vital to agricultural growth in Ghana, offering reliable water access during dry seasons to support year‐round farming, increase yields, and enable crop diversification. Despite Ghana’s abundant water resources, only 2% of the estimated 1.9 million hectares of irrigable land have been developed. This includes approximately 15,980
