要旨/Abstract: This paper presents evidence from a randomized controlled trial evaluating a bundled digital intervention combining weather index insurance, localized weather forecasts, and agricultural extension services delivered via SMS to smallholder maize farmers in southern Mali. The study analyzes data from approximately 1,500 maize farming households across diverse agro-climatic zones and finds that the intervention generates economically and statistically significant improvements in farming practices, leading to substantial increases in maize yields and farm income. These effects are driven by better-informed decision-making enabled by timely and relevant weather information and agronomic advice, which induces adjustments in input use. A cost-benefit analysis indicates that the intervention is highly cost-effective. We discuss implications for scaling digital agricultural services in low-income settings and highlight avenues for future bundles.
