Drought leaves 18 million thirsty in China
20/8/2006 9:34
Hot weather and a severe drought have left millions of people short of
drinking water and millions of hectares of cropland damaged in China.
By
Thursday, 18.03 million people in 15 Chinese provinces and regions were
suffering drinking water shortages caused by the drought, according to Chinese
Ministry of Water Resources.
Forecasts from the meteorological department
say that the hot and dry conditions will continue in the areas hit by drought
and rain is very unlikely.
"The severe drought will not ease up and is
very likely to get worse," the ministry said on its website.
The State
Flood Control and Drought Relief Headquarters has allocated 100 million yuan
(12.5 million U.S. dollars) to the drought-hit areas.
The worst drought
in 50 years left 7.5 million people in Southwest China's Chongqing Municipality
and 3.1 million people in the neighboring Sichuan Province in great
thirst.
The water depth in the Chongqing section of the Yangtze River,
China's longest, hit 3.5 meters (11.5 feet), its lowest in 100 years. About 2.5
million hectares, or 6.18 million acres, of crops were affected.
The
drought is just a small part of a much-larger problem. All of China is running
out of water. By mid-August 2006, drought conditions throughout China had
affected a total 13.88 million people nationwide and destroyed 665,000 hectares,
or 1.64 million acres, of crops in just three months, according to the State
Flood Control and Drought Relief Headquarters.
Although possessing the
fourth-largest fresh water reserves in the world, China, by virtue of its
population, has the second-lowest per capita water holdings in the world,
averaging about 2,200 cubic meters of water per person, a quarter of the world
average.
Figures from the Ministry of Water Resources show that 400 of
China's more than 600 cities lack water and 110 cities, including the national
capital Beijing and adjacent port city Tianjin, face extreme shortages. Beijing
in 2008 can expect to face a water shortage of up to 1.1 billion cubic
meters.
Outside of the cities, the agricultural heartland, which feeds
much of the country and houses the majority of the population, is facing a
similar problem as surface water resources and water tables continue to decline
in volume.
The water shortage nationwide will reach 50 billion cubic
meters by 2030 -- up from the current 6 billion cubic meters, according to the
Ministry of Water Resources.
"While a decade of near double-digit
economic growth has increased people's income and living standards, it
simultaneously has put a serious strain on natural resources and in some cases,
pushed them to breaking point," said He Shaoling, a researcher with China
Institute of Water Resources and Hydropower Research. "The most notable of these
is fresh water."
Droughts, over-exploitation of water resources,
increasing pollution levels, inefficient delivery methods and temperature
increases have led to water scarcity in China, she said, which is "an
unavoidable issue threatening national security".
"The crucial point of
China's developing water crisis is the problem of supply and demand," said Ma
Jun, Beijing author of China's Water Crisis and currently an environmental
consultant with Sinosphere Corporation. "It is urgent to balance the water
shortage with ballooning water demand while allocating water resources more
effectively between north and south, rural and urban, industrial and
individual."
Home to more than 45 percent of China's population, the
northern plains contain only 19 percent of the nation's fresh water stocks,
while housing 58 percent of its cultivated land. The Yellow River, the main
river in the north and heart of Han Chinese civilization, dried up during 21 out
of the 27 years between 1972 and 1999.
Elsewhere in the north, hundreds
of thousands of relatively new wells aimed at drawing ground water and aided by
advances in modern, efficient pumping methods are now drying up as the water
table continues to drop by one meter per year.
While the landlocked
northern areas of China are tortured by drought, the southern coastal cities
also fail to escape the dry spell in spite of richer water resources. "Chemical
spills, rampant pollution and poor stewardship of the land have tainted much of
the area's water supply," said Prof. He.
Though the water resources of
the Yangtze River drainage basin are rich with an annual water runoff of more
than 980 billion cubic meters, which is 37 percent of all the water runoff of
the country, the problems of water pollution and extravagant use of water still
cause severe water shortages.
In rural areas, the situation is grimmer.
More than 300 million people in rural areas are short of clean drinking water
and pollution is so severe that the Ministry of Water Resources estimates 40
percent of water in the country's 1,300 or so major rivers is fit only for
industrial or agricultural use.
The Ministry's 2003 report revealed that
the water condition in 70 percent of cities along the Yellow River failed to
meet the healthy standard while only two lakes out of 11 in the Yangtze River
drainage basin meet water quality standards.
In November 2005, a
nitrobenzene spill caused by an explosion at a PetroChina refinery in
northeastern Jilin Province forced authorities in Harbin, capital of the
neighboring Heilongjiang Province, to temporarily cut water supplies to more
than 3 million local people. The incident prompted the resignation of China's
environmental chief.
Meanwhile, as new industrial developments continue
to mushroom, demand for water is constantly generated. Factories and urban
residents used 34 percent of the nation's water in 2004, up from 25 percent in
1998, according to the Ministry of Water Resources. Consequently, that has hurt
grain production, which fell 8.4 percent to 469.4 million tons during the same
period, according to the National Bureau of Statistics.
"The farmers now
face strong competition for water from cities and industry," said Prof. He
Shaoling. Across the whole of the North China Plain, where half of China's wheat
is grown, 3.6 million wells have been sunk, mostly for irrigation. "The aquifer
below is being steadily drained and the water table is 90 meters below the
surface and dropping by three to six meters a year," she said, adding that
cities have dumped untreated pollutants and waste into the water, making crops
wither and the water unusable.
"This will result in the reduction in the
quality of life of agricultural peasants as crop sizes decrease in line with
water availability," she said. "Also, it will undermine the food security of
China. If current agricultural yields and population increases continue at
present rates of expansion, China may be forced to go to international markets
to import staples," she said.
To address China's water shortage and help
alleviate drought in the north, the government is spending almost 500 billion
yuan (62.5 billion U.S. dollars) on a diversion scheme to ship the water north.
China will build a canal north from the Three Gorges Dam that ultimately will
tunnel under the Yellow River to bring some 38-48 billion cubic meters of water
to the dry Yellow, Huaihe, and Haihe rivers.
"The south-to-north water
diversion project will alleviate shortages in China's northern plain, but it
won't come close to solving them," said Ma Jun. "We should give priority to
conservation because there is now inefficient use of water in agriculture, in
the cities, in the urban and industrial uses along the river."
China has
been a production marvel when it comes to labor costs, but not for water costs.
To produce a unit of GDP, China uses approximately six times more water than the
Republic of Korea and ten times more than Japan, according to Zhai Haohui, vice
minister of water resources.
"What China needs most is a dependable and
safe internal water supply and a clean environment to act as a stable platform
for sustainable economic growth," he said.
So far the government has
adopted a multi-faceted strategy to the water issue, he said. Water conservation
and recycling programs have been introduced and the water price in major cities
including Beijing raised as part of an attempt to stem demand.
In
addition, steps are being taken to curb rapid deforestation and soil erosion
across the country. More innovative forms of water creation, including
artificially seeding clouds with dry ice, are introduced, and hydropower, which
creates large evaporating reservoirs, is increasingly being replaced with wind
power.
"A better management of water resources is also required to reduce
the number of regional fights over water from the Yellow River," Ma Jun said.
"Local officials should be judged not just by how fast their local economies
grow, but also by how well they protect the environment."
"Water is the
lifeline of a country's economy and a regional economy. Economic growth cannot
be allowed to come at a steep environmental cost. It is time for the government
to cope with the realities of declining water stocks and their implications for
the whole society," he said.
