Political and economic water wars are already being waged in several regions, reflected in dam construction on international rivers and coercive diplomacy or other means to prevent such works.

政治和经济上的谁战争已经在不少地区打响，国际河流上的水坝建设以及用强制外交或其他手段防止这类工程的尝试就是明证。比如，埃塞俄比亚在青尼罗河上修建大坝便引起了静悄悄的谁战争，埃及已表示要进行隐蔽或公然的军事报复。
