Smart irrigation systems have been introduced to improve agricultural productivity in coastal Mozambique, particularly among smallholder farmers who face challenges with water scarcity. A mixed methods approach was employed, integrating quantitative data on system usage and qualitative insights from farmer interviews to evaluate system efficacy and acceptability. Overall, 65% of farmers adopted the smart irrigation systems with significant water savings averaging at 20%, indicating a promising adoption rate and efficiency improvement. The mixed methods study highlights the potential for smart irrigation systems in enhancing agricultural sustainability among smallholder farmers in coastal Mozambique. Policy makers should consider incentivizing the adoption of these systems through subsidies or other support mechanisms to further promote their use.
