Abstract
Drought conditions in Mali have significantly impacted agricultural productivity, necessitating innovative irrigation solutions to ensure food security and economic stability. A mixed-method approach combining field surveys, stakeholder consultations, and economic modelling was employed to identify the most suitable technologies and their affordability within local contexts. Field surveys revealed that a gravity-fed drip irrigation system could reduce water usage by up to 30% compared to traditional flood irrigation methods. Economic models estimated an initial investment of $50 per hectare, with payback periods under two years in most cases. The findings suggest that the proposed low-cost irrigation systems can be implemented at scale without compromising agricultural productivity, thereby enhancing resilience against future droughts. Communities and policymakers should prioritise the adoption of these cost-effective solutions through targeted subsidies and capacity building programmes for local farmers. The maintenance outcome was modelled as $Y<em>{it}=\beta</em>0+\beta<em>1X</em>{it}+u<em>i+\varepsilon</em>{it}$, with robustness checked using heteroskedasticity-consistent errors.
