The World in 2050: Four Forces Shaping Civilization's Northern FutureThis БЂњSouth-to-North Water DiversionБЂ«megaproject will link together four major drainage basins and build three long canals running through the eastern, central, and western parts of the country. Its costs will include at least USD $62 billionБЂ”more than three times the cost of ChinaБЂ™s Three Gorges DamБЂ”the relocation of three hundred thousand people, and many negative environmental impacts. When finished, the amount of water artificially transferred from south to north each year will total more than half of all water consumption in California.521 Might another megaproject emerge to redirect water from north to south, say from Canada to the United States, or from Russia to the dry steppes of central Asia? There are certainly some precedents, and not just the one going on now in China. The last century saw the construction of many major engineering projects in the Soviet Union and North America, including two huge schemes to transfer water from one drainage basin to another: CanadaБЂ™s James Bay Project for hydropower, and CaliforniaБЂ™s State Water Project, a massive system of canals, reservoirs, and pumping stations to divert water from the northern to southern ends of the state ...» |
