Will armies battle each other, as the cry for “blue gold” gets furious? Will “water wars” be as prevalent as conflict for the “black gold” of oil? Two documentary films have wetted public interest – Blue Gold: World Water Wars, and Last Call at the Oasis, and a dystopia novel – The Water Wars – warns of its imminence.
In actuality, history’s pages are already splashed with dozens of conflicts. In 2,450 B.C. the Sumerian cities of Lagash and Umma warred over Tigris-Euphrates water. More recently, Senegal and Mauritaniabattled in 1989 over grazing rights in the Senegal River Valley – hundreds were killed, 250,000 fled their homes. The Pacific Institute provides an excellent map and timeline of 225 water skirmishes.
