  • Essay / Water shortage in China - 1105

    Water shortage is a growing problem in most countries around the world. For China, which is home to 20% of the world's population and only 7% of available water resources, this problem could become catastrophic (Hofstedt 2010: 72). Therefore, certain actions and measures should be taken to avoid or at least mitigate a future water crisis in China. In this work, the following three solutions will be proposed and analyzed in terms of effectiveness and applicability: improving water use efficiency; adopt local water resources control agencies; a reasonable price for water. Most of the water consumed in China is not used rationally. The cause that intensifies China's water shortage is inefficient water use. For example, 65 to 70 percent of China's water consumption is devoted to agricultural needs, but more than half of this amount evaporates, infiltrates, and is lost (Roberts 2009). Furthermore, the majority of the 20-25% occupied by Chinese industry is not recycled (Brown 2008a, 16; Roberts 2009). Obviously, improving water distribution technologies and water management quality can be one of the options to reduce water shortage in China. There are many different methods for improving water delivery efficiency. First, irrigation technologies need to be improved. Chinese farmers can use drip and constriction irrigation methods instead of traditional “surface” methods such as furrow and flood irrigation. The drip irrigation method is mainly used in arid and semi-arid areas and increases irrigation efficiency by transporting water directly to the roots of irrigated plants. The emitters spray the soil beneath the roots with water that is introduced into the plant through pipes, reducing water evaporation, deep percolation and leakage. In contrast, fur... middle of paper ... raising the price of water and keeping it at a reasonable level will inevitably lead to an increase in the cost of other products, which is unacceptable in China (Hofstedt 2010, 76). -77). Therefore, this measure must be adopted consistently, depending on the overall situation in the world and in China in particular. In conclusion, this work evaluated several solutions to China's water shortage: improving water use efficiency, adopting local water resource control agencies, and reasonable water pricing. It was revealed that all the proposed solutions could be effective, but they need to be properly applied and, probably, their combination can help combat water shortage in China. However, some other solutions should have been evaluated, such as water recycling, and this work could serve as a basis for further studies..
