在大多数跨界河流流域，水是其沿岸国家之间争论的焦点。考虑到这一点，本文评估了上游取水对中游和下游子流域的水安全在国家流域网格空间分辨率的月度影响。在442个次流域地区，大约有21.8亿人全年经历不到1%的水压力加剧。此外，由于上游取水，336个次流域地区的21.2亿人至少在一个月内经历了水紧张程度的变化，从没有水紧张到水紧张类别之一。尽管在许多流域有明显的上游影响，但不存在具有严重社会、经济、政治和环境后果的水争端。这可能表明，严重的水争端是复杂的社会经济和政治互动的结果，而不仅仅是因为上游取水造成的缺水。因此，了解这种关系对于确定跨界河流流域内水冲突的拐点至关重要。
Water, in most of the transboundary river basins, is a bone of contention among their riparian states. Taking this into account, this article assessed the monthly impact of upstream water withdrawal on the water security of middle stream and downstream sub-basins at a country-basin mesh spatial resolution. Roughly 2.18 billion people in 442 sub-basin areas experience water stress intensification by less than 1% throughout the year. In addition, 2.12 billion people in 336 sub-basin areas experience water stress level change, from no water stress to one of the water stress categories, for at least one month as the result of upstream withdrawal. Even though there is a clear upstream impact in many of the basins, water disputes with severe social, economic, political, and environmental consequences are nonexistent. This might be an indication that grave water disputes are the result of complex socio-economic and political interactions, not merely because of water deficits due to upstream water withdrawal. Therefore, understanding this relationship is crucial in identifying inflection points for water conflicts within transboundary river basins.
