Global renewable surface water resources 2020, by main country

Brazil has the largest renewable surface water resources worldwide, at an estimated 8,647 billion cubic meters. This is roughly twice the amount of renewable surface water available in Russia, which has the second-largest figure. In contrast, many countries worldwide lack renewable surface water resources, such as Kuwait, which has the highest renewable water resources dependency ratio worldwide. Surface water is any body of water above ground, such as streams, rivers, and lakes.

巴西拥有全球最大的可再生地表水资源，估计达8,647立方千米。这一数字约为俄罗斯可再生地表水资源的两倍，而俄罗斯位居第二。相比之下，全球许多国家缺乏可再生地表水资源，例如科威特，其可再生水资源依赖比率位居全球之首。地表水是指地面以上的任何水体，如溪流、河流和湖泊。
