In an attempt to identify solutions to the effects of erratic rainfall patterns and droughts that limit agricultural production growth, the Rwandan government has recently increased investments in irrigation development. In this study, we analyze the adoption of small-scale irrigation technologies (SSITs) and its impact on land productivity using cross-sectional data from a sample of 360 farmers in Rwanda. The study uses the propensity score matching technique to address potential self-selection bias. Our results reveal that adoption decisions are significantly influenced by factors such as education, farm size, group membership, gender, extension services, access to credit, access to weather forecast information, risk perceptions, access to a reliable source of water for irrigation, awareness of rainwater harvesting techniques, and awareness of subsidy programs. In addition, the results show that the adoption of SSITs has a significantly positive impact on land productivity. The study concludes with policy implications that highlight the need to promote the adoption of SSITs among farmers as a strategy to improve agricultural productivity and food security in Rwanda.

为了找出限制农业生产增长的不稳定降雨模式和干旱影响的解决方案，卢旺达政府最近增加了对灌溉发展的投资。在这项研究中，我们使用来自卢旺达 360 名农民的样本的横截面数据分析了小规模灌溉技术 (SSIT) 的采用及其对土地生产力的影响。该研究使用倾向得分匹配技术来解决潜在的自我选择偏差。我们的结果表明，采用决策受教育、农场规模、团体成员、性别、推广服务、获得信贷、获得天气预报信息、风险认知、获得可靠的灌溉水源、意识等因素的显着影响雨水收集技术，和补贴计划的认识。此外，结果表明，采用 SSIT 对土地生产力有显着的积极影响。该研究的结论是政策含义，强调需要促进农民采用 SSITs 作为提高卢旺达农业生产力和粮食安全的战略。
