"Some Chinese scientists say the diversion could destroy the ecology of the
southern rivers, making them as useless as the Yellow River. The government
has neglected to do proper impact studies, they say. There are precedents in
the United States. Lakes in California were damaged and destroyed when the
Owens River was diverted in the early 20th century to build Los Angeles.
"midlevel officials in water-scarce Hebei Province are frustrated that four
reservoirs in their region have sent more than 775 million cubic meters, or
205 billion gallons, of water to Beijing since September 2008 in an '
emergency' supplement to the middle route" of water diversion.
"Overseers of the eastern route, which is being built alongside an ancient
waterway for barges called the Grand Canal, have found that the drinking
water to be brought to Tianjin from the Yangtze is so polluted that 426
sewage treatment plants have to be built; water pollution control on the
route takes up 44 percent of the $5 billion investment, according to Xinhua
"Officials in Tianjin are so skeptical of the eastern route’s ability to
deliver drinkable water that they are looking at desalinization as an
alternative.
"At the start of the route, the water level of the Danjiangkou Reservoir on
the Han River has been raised 43 feet to 558 feet so that the water can flow
downhill to Beijing.
"The demands of the north will not abate. Migration from rural areas means
Beijing’s population is growing by one million every two years
"The planning for Beijing’s growth up to 2020 by the State Council already
assumes the water diversion will work * * * City planners see a Beijing full
of golf courses, swimming pools and nearby ski slopes — the model set by
the West.
Note:
(a) Danjiangkou Reservoir
http://en.wikipedia.org/wiki/Danjiangkou_Reservoir
(丹江口水库; a multi-purpose reservoir in Xichuan County, Henan and
Danjiangkou City, Hubei province; onstructed in 1958, and at the time was
one [of] the largest reservoirs in Asia; Primary inflows 丹江; Primary
outflows 汉江 (historically 汉水) )
(b) Owens River
http://en.wikipedia.org/wiki/Owens_River
(drains through the Owens Valley; terminates at Owens Lake; its flow is
greatly diminished by diversion into the Los Angeles Aqueduct since 1913. It
is a major example and cause in the long-running California Water Wars)
(c) If one reads the quotations, probably there is no need to read the
report itself. But do not forget to see the slide show.

"Affluent countries like Saudi Arabia, South Korea, China and India have
descended on fertile plains across the African continent, acquiring huge
tracts of land to produce wheat, rice and corn for consumption back home. *
* * And in countries like Congo and Zambia, China is acquiring land for
biofuel production.
"Since rainfall in Egypt is negligible to nonexistent, its agriculture is
totally dependent on the Nile.
"The Nile Waters Agreement, which Egypt and Sudan signed in 1959, gave Egypt
75 percent of the river’s flow, 25 percent to Sudan and none to Ethiopia.
* * * Ethiopia — never enamored of the agreement — has announced plans to
build a huge hydroelectric dam on its branch of the Nile that would reduce
the water flow to Egypt even more.
My comment:
(a) "It [Ethiopia] was one of only four African members of the League of
Nations. After a brief period of Italian occupation, Ethiopia became a
charter member of the United Nations."

(b) Two years ago an Ethiopian told me about Ethiopia's discontent with teh
1959 agreement, threatening to uniterally build dams at upstream of Niles,
which is totally comport with international law. Egypt threatened war in
return. |
