How much water?
Especially how much from every country? We don’t have enough data because of sparse
gauge station in high mountain. We try to apply GIS tool to obtaining water
resources and other related information by means of open data.

blended river flow
Surface Runoff here is blended river flow that represents a composite of observed and modeled river flow. (See details in Fekete, B. M., C. J. Vorosmarty, W. Grabs. 2002. High-resolution fields of global runoff combining observed river discharge and simulated water balances).
For mountain area, it close to natural runoff. For plain area, it close to actual runoff.

2. Water use trend of China vs GWRDP
Why talk about this? There are worry that China will divert
water from Yaluzangbu!
Great West Route Diversion Project (GWRDP)
‘Water of Tibet save China’ Li Ling, Guokai
Some others
Changjiang
Zhujiang
Huanghe
Huaihe
South to North Water Transfer Project and GWRDP
East Rout
MiddleWest
GWRDP???
Is GWRDP Feasible?
For Tibet Autonomous Region, it use very little water: only 1% of runoff withdrawn for human use, mainly for irrigation.
But North China is lacking of water. Will or not North China divert Yaluzangbu? For answer this, we should see the water use
trend of China!

The Kuznets curve law of industrial water use evolution
There is a turning point of water use form increasing to decreasing

Turning point
Conclusion about water use trend of China
Water use is closing the climax!
Not only for whole China, but also/especially for North China
So China has no need to divert water from Yaluzangbu!
Long term water supply and demand planning of China
Set up total water use limitation for Whole China and every province!
For year 2020, it should be less than 670 billion m3;
For year 2030, it should be less then 710 billion m3!
Compared to recent 598 m3, it’s permitted to increase about 100 billion. And engineering projects has been planned to provide those added supply, while no project of diverting water from Yaluzangbu is considered.
For my personal opinion, it’s not possible for water use of China to reach high to 650 billion!
GWRDP not only not necessary, also not feasible!
Too far: 2000km away Too high the lifting of water: more than 1000m Too difficult: high elevation, new technical
movement, too complex geological condition Too dangerous: too frequent geological disaster,
such as land sliding, earthquake Too expensive!
The Chinese government has never support and planned it!
Bo sea to Xinjiang Diversion Project: use salt water to harness desert, and let increased vapor to rain and change the desert to oases!
Romanticism of engineering
Hydropower station will come!
Not mega-dam! Only Small reservoir, canals and pipeline It’s sure there will be some disturbing to
ecosystem, but hydropower is greener compared to coal and sustainable. The key point is to look for the balance point between hydro-energy development and ecological protection.
3. Make Water Peace linkage
Will really water substitute for oil as the reason of war?
Will be a water war between India and China?
Long history of exchange
From ancient time, China had very strong linkage with South-East Asia and South Asia!
Buddha Silk Road Sea Silk Road Ancient Tea and Horse Road Shannxi, Sichuan,
Yunnan, Tibet to India
Follow the example of EU!
See each other as friend, not enemy. Attitude may auto-prove!
Seek for the truth! Take care of data and the fact; avoiding misunderstanding
Maintain exchange! Show good will for cooperation! China has no intention, no will to use water as
weapon to India! Even China want to do so, it’s not feasible! Pakistan and Bangladesh also located in the lower reach, if China flood India, can these two friend countries be saved?
What can we do by ourself?
Personal and civil exchange Knowledge sharing Professional explanation and propaganda to
media Cooperative research Suggestions to the government to promote
official cooperation
