Chapter 2 Water Condition
China has still economically developed and the population has grown over
1.3 billion. However, with regard to water, there is only 1/4 water of
world average.
According to an estimation, the population in China will grow to 1.6 billion
by 2030. As the result, the water resource for one person decrease to 1760㎥,
and it will reach to 1700㎥ which is the international indication for lack
of water. In many large cities of China, lack of water has already emerged.
When it sees at the city which has more than one million population, 30
large cities out of 32 large cities suffers from lack of water. Especially,
lack fo water is the most serious in Beijing.
In dry areas located in North, due to evaporation from water surface or overtaking of underground water, lack of water problem becomes more serious issue. On the other hand, South where provide lots of water, water contamination in rivers, lakes, and marshes became serious problem so that there is less water which people can use. Consequently, even rich water area such as delta area where has Chang Jiang and Zhu Jiang has issue of lack of water.
As you can see, the water issue in China is symbolic of world water issue.
Water issue in China where has been regarded as world industry or kitchen
is the problem for not only China but also the world.
In Japan Water Guard, as the measure toward world water issue, we carried
out water purification project for China contaminated water environment.
Points about China water condition
・Water resource for one person in China is 1/4 of world average
・90% of underground water in city and 75% of rivers, lakes, marshes are contaminated.
・Due to water contamination, 7 hundred million people suffer from drinking polluted water.
・Due to disease caused by water, significant large number of early death has emerged.
・Government has plan to decrease water contamination by funding toward sewer treatment facility
・Although certificated drinking water are sold in city such as Beijing, there are forged drinking water. Thus, it is difficult to buy safe drinking water.
