Water water everywhere and not a drop to drink (part 2)

In rural Finland there are over a thousand water cooperatives serving farm businesses and villages. Whilst licensed by the government and allotted a limit to the amount of water they can extract, the cooperatives have complete control over price. This means they can offer favourable rates to their members because their decision is not influenced by fluctuations of the market. The Finnish water cooperatives also have the network benefits of other partnering with other regional associations. If for instance the water quality in one area is not sufficient, due to extenuating natural circumstances, the cooperative may buy water from a neighbouring cooperative-owned water network, thus ensuring continued low prices and supply dependency.

Water water everywhere and not a drop to drink (part 1)

the human body weight, needs to be topped up on a regular basis and we cannot go without it for more than about week. As well as drinking it, we also use water for cooking and sanitation, not to mention industrial processes. Yet despite water being essential to our survival, more often than not in the West, we treat it with distain. A fact reflected in its low price (compared to petrol or electricity -- things we may be addicted to but can live without?) and how the developed world fritters it away (you may leave the kitchen tap running into an unplugged sink at home but you would not pour petrol from the station pump down the drain, right?).

What makes matters worse in terms of our taking water for granted, is that despite 70% of the Earth’s surface being covered by water, only 2.5% of the total volume is freshwater resources and fit for human consumption. Coupled with the facts from the WBCSD and FAO that in 60% of European cities with more than 100,000 people, groundwater is being used at a faster rate than it can be replenished, by 2025, 1,800 million people will be living in countries or regions with absolute water scarcity, and two thirds of the world population could be under stress conditions.

cons of hydro-power (hydroelectric) in China

First of all, many people that live in southwest China and other locations with huge hydropower potential will be relocated and forced to abandon their households once these big installation projects take place. The typical example is the Three-Gorge Dam.  Good news is that Southwest China isn't that heavily populated as some other parts of China, but still lots of people will have to abandon their homes and many of them are already worried about their future.
The change of the Three-Gorge Dam in china (in 1987 and 2006):
Three-Gorges Dam in China

For example, Dadu River that has the biggest hydropower potential capable of having 22 power plants installed in the near future will cause relocation of more than 100,000 people once if this project starts. Some environmentalists and ecologists call this massive hydropower project as the second worst ecological disaster in China's history, comparable to terrific deforestation that was happening in period between the 1950s and the 1990s.

Water ways are not the same as they used to be since hydroelectric power plants altered their way. And this has destroyed many different eco-systems. This scenario should be expected in southwest China.

China has many nature conservation areas but that isn't preventing them from building new hydroelectric power plants in these areas, despite of laws and different other regulations and this trend is mainly the result of increased energy demand. This problem has big, both economic and ecological impact. and China will have to choose whether to preserve this area as nature conservancies or to turn them into hydropower generator centers.

Water shortage (Water scarcity): global crisis

There are more than 600 cities in China. But most of them (To be exact, it's more than 400 cities) suffer from water scarcity. As many as 7 billion people throughout the world may face a water shortage by 2050 if the present situation continues. Sustainable & green development is so important to us.

The World Health Organization (WHO) says that at any time, up to half of humanity has one of the six main diseases -- diarrhea, schistosomiasis, or trachoma, or infestation with ascaris, guinea worm, or hookworm -- associated with poor drinking water and inadequate sanitation.

Water shortage (Water shortage) has been a global crisis.
water situation worldwide

China has about 1.3 billion people. Water scarcity is becoming more and more serious. In dry Northern China, due to overpumping and over-fast development of the industry, more cities are diverting water from agriculture and farmers are going out of business. Some Chinese rivers are so polluted with heavy metals that they can't be used for irrigation.
