Water shortage is a growing problem for most countries in the world. For China, which has 20% of world’s population and only 7% of available water resources, this problem may become catastrophic (Hofstedt 2010, 72). Therefore some actions and measures should be performed to avoid or at least to weaken future water crisis in China. In this work the following three solutions will be proposed and analyzed in terms of efficiency and applicability: water usage efficiency improvement; adopting the local agencies on controlling water resources; reasonable water pricing.
Most of water consumed in China is not rationally used. The cause which intensifies the water shortage in China is water inefficient use. For instance, 65%-70% of Chinese water

(Hasan and Özay 2002, 73-74). As Albiac (2008) reports, development of pipe network distribution and drip irrigation methods in other countries led the farmers to have remarkable irrigation efficiency in drought (143). Such technologies have already been used in China, but they are not widely spread in China’s agriculture. One investigation in China on rice paddy irrigation systems development was performed and it revealed that using the fry-foot paddy irrigation (when no water flooded the field) instead of flooding irrigation (when the rice field is completely flooded) significantly (40-60%) reduces water consumption (Xiaoping, Qiangsheng and Bin 2004, 351). Furthermore, drip irrigation method was applied in arid Northern China and it raised the water usage efficiency (Du et al 2007). However, introduction of new irrigation technologies faced some difficulties in China. As Hodstedt (2010) noticed in his article, the water saved by these technologies such as drip irrigation systems was simply spent on more food production and, therefore, did not reduce the water shortage. Also, as he reported, this caused two other environmental problems. Firstly, the water, which was the supply for underground water and aquifers as it was lost by deep percolation and leakage, became unavailable after the water-saving technologies were introduced and this strengthened the aquifers depleting along with its overpumping. Secondly, after
One reason for China's water shortage is pollution. Only 56% of municipal sewage is treated in some form (doc F). 20 Billion of untreated wastewater is directly deposited into water bodies (doc E). When something gets in water you can not drink it because it is polluted.
China water scarcity is ,so bad south china is having to give north China, 45 billion cubic meters of water per year. The Glaciers are shrinking ,so North China dry season will be very dry(doc A).There are three main causes of China’s water scarcity crisis is bad Government policy, population growth and urbanization ,and Of these, the biggest driver is industrialization.
According to the International Water Management Institute environmental research organisation global water stress is increasing, and a third of all people face some sort of water scarcity. Where demand exceeds supply and no effective management operates, there will be conflicts between the various players involved.
North China is lacking water.China is a big country and needs water, but most of its rivers are drying up. There are three main causes of China’s water scarcity crisis: Global warming, urbanization, and industrialization. Of these three important drivers, there is one that is much more important than the others, industrialization.
China’s water supply is in danger. Throughout time, there many glaciers, rivers, and other sources of water until scarcity reigned. Due to Population rapidly growing, Global Warming, and developing industries, China’s water supply decreased significantly. Population was growing to quickly, Global Warming melting and shrinking our main sources of water, and lastly, development of industries requiring a big supply of water for their business such as manufacturing. As you can see, these factors has been affecting China greatly. There are three main causes of China’s water scarcity crisis: Global Warming, Population Growth/Urbanization, and Industrialization. Of these, the biggest driver is Industrialization.
In accordance with many facts, China’s Water Scarcity Crisis has many factors. However, the three most important causes of China’s water-scarcity crisis are Global Warming, Population Growth and Urbanization and especially Industrialization. With the erupting downfall of the great country’s water crisis, China needs to address all these components immediately. If not, the country might as well write out their death
Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.
As we all understand, the Earth has many landmarks and it is these physical features that create an abundant and organized system within which we thrive. One of the most abundant natural resources on the planet is water and the importance of this element is as crucial as any other. For the fortunate few who get to utilize it, this amazing reserve provides us with our necessity for daily consumption as well as our ability to grow just about anything we please. Common irrigation practices are essential for gathering water into a contained area to grow crops that would not typically survive in areas without heavy rainfall. As a matter of fact, “irrigation is an ancient practice that originated along the Tigris and Euphrates Rivers in what is now Iraq” and is now the result of an estimated 40 percent of all crops grown around the world (Water Encyclopedia). This tactic has provided many different cultures with numerous varieties of crops as well as growth in crop yield which in turn dramatically advances human civilization. As we develop into a more progressive society, the tools and systems used to grow our crops also become more intelligent as well as sustainable
The world’s supply of water is in steep decline as more and more is being used each year by more and more people around the globe. Currently, 800 million people do not have access to a drinking source. At the current rate, 1.8 billion people could be living in areas of absolute water scarcity by 2025.
For those causes and effects, the California officials have come up several solutions for solving this problem. The first solution is education. The residents in California do not have enough concept of saving water, so they use a lot of water to water their lawns and plants, wash their clothes daily although they have just worn a t-shirt with jean for two hours, and keep water flowing when they are brushing their teeth. Through education, people will notice the problem of water shortage in their home country, and understand the correct way to save water. The second solution is adding the cost of using an amount of water, and we will set a water usage average line for the residents. It means that you will be cost extra money when the amount
According to history of China, water consumption, growing population and demand for higher living standards were increasing steadily since the 1950s, when industrial development of the country started. In theory that could lead to new economic era and growth of the country, but in practice that caused one of the most important environmental problems in China. First of all, the pollution of water resources in this country goes deep into history in the 1970s. According to Wang (1989), the situation hasn’t changed for the better and the rate of pollution increased rapidly. Even nowadays the government of China cannot tackle
Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes
After intense search we were able to find different types of irrigation systems that represent different forms of irrigation which are also the most commonly used in their category and generally here in the central valley. There are three categories that form the irrigation system: flood, sprinkler, and drip. Flood irrigation providing us with furrow irrigation, sprinkler irrigation having the center pivot irrigation, and drip irrigation having its own beneficial water conservation uses, each which waters our crops but not all in the most effective way possible. Furrow irrigation for example tends to flood the crops with water in order to water them, which is not good for the crops as they will be taking in too much water and drowning. When farmers use furrow irrigation they use as much water at once in
There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is beginning to show its effects in first world countries, but is a current major problem facing lesser developed countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. In developed countries the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the vast majority of the population. Seventy one percent of
As the worlds population grows, it is forced by circumstances that it has created to face the limitations of the worlds resources. Most people in the US have always been fortunate enough to have enough of whatever they wanted. When something they like breaks or wears out, they throw it away or buy a new one, and they often don’t even make an attempt to repair an item. They neglect basic maintenance until they damage their belongings beyond repair, and expect that they’ll always have enough. But some things are beyond their control, beyond there power or financial ability to replace or repair. The world’s drinking water supply is one of these without concern, without attention, without preventative maintenance and reclamation and
