近年墨西哥国内旱情严重，本国用水需求激增，在平衡国内需求和国际义务上面临巨大挑战。 然而，近十年来，受气候变化影响，墨西哥干旱频率、强度和持续时间呈上升态势。自去年11月底以 来，墨西哥多地遭遇严重旱情，截至今年中旬，墨西哥46.5%的土地处于中度至异常干旱状态。此外， 墨西哥北部农业和城市迅速发展，导致实际用水量远超预期，对水资源的过度消费和管理不善也进一步 加剧水资源短缺。 牛海彬表示，长期以来，美墨之间水资源分配的运作相对成熟，双方均建设多座水坝、水库以协调跨国 用水。但如今墨西哥在平衡国内用水和国际义务上面临很大压力。 对于美国总统特朗普发出的不还"水债"就加征关税的威胁，墨西哥总统辛鲍姆9日表示，墨西哥计划增 加对美供水量。 据新华社报道，美国总统特朗普8日在社交媒体发帖称，如果墨西哥不立即向美国供水，美国将对墨西 哥产品额外征收5%的关税。他声称墨西哥违反了两国的水资源共享条约。 特朗普称，墨西哥在过去5年未能遵守协议，现在欠美国超过约9.8亿立方米供水量，美国要求墨西哥在 12月31日前释放约2.47亿立方米供水，其余部分尽快交付。 辛鲍姆对此表示，干旱和输水管道的规模限制了墨西哥向美国输送"更 ...
