The demand for water is rising rapidly, particularly in agricultural and environmental sectors. This has led to more competition to access limited and scarce water resources. Therefore, choosing an appropriate approach to manage water resources, distribution and allocation, to attain sustainable agriculture is critical for every country worldwide. The most well-known method to preserve or store water and adaptation strategy to climate change is irrigation. This paper wished to understand the impact of irrigation on farmers’ income in Laos, especially from rice, which is the main crop of rural people. The difference in differences (DID) method was employed to estimate the regression results. The DID was estimated by the pooled OLS of the effect on the log of households’ rice farm income and log of households’ total income with household head’s age, education, gender, household size, ethnicity and harvest areas variables pointing out the coefficients of the outcome variables of interest (after treatment) were 0.037 and 0.076 with positive sign but statistically insignificant. The result implies irrigation has no impact on rice products. In other words, irrigation does not increase households’ income. The finding indicates the type of irrigation, the location of the operation headquarters and the management system or governance are crucial factors for explaining the impact of irrigation on the rice products in Laos.

老挝农村灌溉和扶贫公共投资

对水的需求正在迅速上升，特别是在农业和环境部门。这导致了获取有限和稀缺水资源的更多竞争。因此，选择适当的方法来管理水资源、分配和分配，以实现可持续农业对全世界每个国家都至关重要。最广为人知的保存或储存水和适应气候变化策略的方法是灌溉。本文希望了解灌溉对老挝农民收入的影响，尤其是稻米，这是农村人口的主要作物。差异中的差异（DID）方法用于估计回归结果。DID 是根据户主年龄对家庭稻田收入对数和家庭总收入对数影响的汇总 OLS 估计的，教育、性别、家庭规模、种族和收获地区变量指出感兴趣的结果变量（治疗后）的系数分别为 0.037 和 0.076，具有正号，但在统计上不显着。结果表明灌溉对大米产品没有影响。换言之，灌溉不会增加家庭收入。调查结果表明，灌溉类型、运营总部的位置以及管理系统或治理是解释灌溉对老挝大米产品影响的关键因素。结果表明灌溉对大米产品没有影响。换言之，灌溉不会增加家庭收入。调查结果表明，灌溉类型、运营总部的位置以及管理系统或治理是解释灌溉对老挝大米产品影响的关键因素。结果表明灌溉对大米产品没有影响。换言之，灌溉不会增加家庭收入。调查结果表明，灌溉类型、运营总部的位置以及管理系统或治理是解释灌溉对老挝大米产品影响的关键因素。
