Topic > Water shortages in China - 1105

Water shortages are a growing problem for most countries around the world. For China, which has 20% of the world's population and only 7% of available water resources, this problem could become catastrophic (Hofstedt 2010, 72). Therefore, some actions and measures should be taken to avoid or at least weaken the future water crisis in China. In this work, the following three solutions will be proposed and analyzed in terms of efficiency and applicability: improvement of efficiency in water use; the adoption of local authorities on the control of water resources; reasonable water prices. Most of the water consumed in China is not used rationally. The cause that aggravates water shortages in China is the inefficient use of water. For example, 65%–70% of the water used in China is spent on agricultural needs, but more than half of this amount evaporates through percolation and waste (Roberts 2009). Furthermore, most of the remaining 20–25% occupied by Chinese industry are not recycled (Brown 2008a, 16; Roberts 2009). Obviously, improving water distribution technologies and management quality can be one of the options to reduce water scarcity in China. There are many different methods to improve the efficiency of water distribution. First, irrigation technologies should be improved. Farmers in China can use drip and constriction irrigation methods instead of traditional “surface” irrigation 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. Drippers spray the soil under the roots with water that is introduced into the plant via pipes, decreasing water evaporation, deep percolation and losses. On the contrary, the hair… half the paper… increasing the price of water and maintaining it at a reasonable level will inevitably lead to the increase in the cost of other products, which is unacceptable in China (Hofstedt 2010, 76 -77 ). Accordingly, this measure should be taken consistently, in accordance with the global situation in the world and in China in particular. In conclusion, this work evaluated several solutions to water scarcity in China: improving water use efficiency, adopting local agencies to control water resources, and reasonable water prices. It was revealed that all the proposed solutions could be effective, but they should be applied correctly, and probably their combination can help combat water scarcity in China. However, some other solutions should have been evaluated, such as water recycling, and this work could become a basis for further studies.
