Water scarcity has increased dramatically in many parts of the world and has become a major environmental problem globally in recent years. To address this challenge, researchers are continuously exploring and investigating different water sources and the relevant abstraction method. South Asian countries are not an exception in this regard. Specifically, how optimization has been done during the water abstraction process is becoming a key research agenda in South Asian region. This study attempts to systematically review the optimization of groundwater abstraction research in the South Asian region. First, bibliometric analysis has been performed to quantitatively assess the current research trends in the optimization of groundwater abstraction research. Second, a qualitative analysis has been done to get more insights into the different abstraction methods and simulation models used in groundwater abstraction research. This study has addressed the gap and explored research streams through scientific and conceptual mapping of the optimization of groundwater abstraction research. As revealed, the year 2020 is the most productive in groundwater abstraction research. Indian Institute of Technology and India were found to be the most impactful institution and countries in this field. The most studied area in groundwater abstraction research was found to be sustainable groundwater management, the geochemical process of controlling groundwater evolution, the Spatio-temporal variability of groundwater and the supply-demand of water during dry seasons. As revealed, statistical and mathematical modelling analysis is the most used approach in these studies. The findings of this study suggested that the water scarcity problem can be fixed by improving the design and operational techniques of the groundwater abstraction method and by using the different water sources collectively. This study further provides future directions and opportunities for research in the field of the groundwater abstraction process.
世界许多地区的水资源短缺问题急剧增加，近年来已成为全球主要的环境问题。为应对这一挑战，研究人员不断探索和研究不同的水源及相关取水方法。南亚国家在这方面也不例外。具体而言，取水过程中的优化方式正成为南亚地区的一项关键研究议程。本研究试图系统回顾南亚地区地下水取水优化研究。首先，进行了文献计量分析，以定量评估地下水取水优化研究的当前趋势。其次，进行了定性分析，以更深入了解地下水取水研究中使用的不同取水方法和模拟模型。本研究通过对地下水取水优化研究进行科学和概念性映射，填补了空白并探索了研究方向。结果显示，2020年是地下水取水研究产出最多的一年。印度理工学院和印度被发现是该领域最具影响力的机构和国家。地下水取水研究中研究最多的领域是可持续地下水管理、控制地下水演变的地球化学过程、地下水的时空变异性以及旱季的水供需情况。结果显示，统计和数学建模分析是这些研究中最常用的方法。本研究结果表明，通过改进地下水取水方法的设计和操作技术以及共同使用不同水源，可以解决水资源短缺问题。本研究还为地下水取水过程领域的未来研究提供了方向和机会。
