几十年来，世界各国一直在促进灌溉扩张，作为促进农业增长、平滑生产风险和减轻农村贫困的一种方法。尽管它有明显的优势，但次优的采用率仍然存在。根据现有的文献，灌溉采用的决定因素往往高度依赖于文化，上下文，和/或当地的制度因素。然而，来自不同地区的研究确定了一系列一致的因素。因此，为了能够从这些研究中得出可推广的推论，对灌溉采用研究进行了全球地理代表性评估，以确定影响灌溉的因素是否是地理，认识论或学科偏见的结果。研究结果表明，在研究农户灌溉决策时，存在多重地理偏差。在灌溉率很低或很高（>1%）、交通便利、年平均降雨量适中、耕地覆盖率适中的地区，正在对这一主题进行更多的研究。研究结果表明，有必要在灌溉很少或没有灌溉的地区扩大研究工作，以确定制约因素，并帮助加快这些地区农村社区的经济增长、减贫以及粮食和生计安全。
For decades, nations around the world have been promoting irrigation expansion as a method for improving agricultural growth, smoothing production risk, and alleviating rural poverty. Despite its apparent advantages, suboptimal adoption rates persist. According to the existing literature, determinants of irrigation adoption are often highly dependent on cultural, contextual, and/or local institutional factors. Yet, studies from diverse geographies identify a consistent set of factors. Thus, to be able to make generalizable inferences from such studies, a global geographic representativeness assessment of irrigation adoption studies was conducted to determine whether identified factors influencing irrigation were the result of geographic, epistemological, or disciplinary biases. The results indicate that multiple geographic biases exist with respect to studying farmers’ irrigation adoption decision-making. More research on this topic is being conducted in regions that have little to a high percentage of irrigation (>1%), are readily accessible, receive moderate amounts of average annual rainfall, and have moderate amounts of cropland cover. The results suggest the need to expand research efforts in areas with little to no irrigation to identify constraints and help accelerate economic growth, poverty reduction, and food and livelihood security for rural communities in these regions.
