One of the biggest problems in the world is water scarcity. Almost all countries suffer from it and many of them cannot find the most effective solution to avoid this difficulty. The meaning of the world water crisis is very easy to understand, but solving it is very difficult. The amount of world water is limited, as the population is growing fast; the necessity of water use is growing even faster. This essay will examine the water crisis specifically in China, because it is the country with the most serious water shortage problems in the world. Also, this essay will suggest possible solutions on solving these problems and evaluate them. Although to stop the water shortage problems is difficult and costly, and takes a lot of…show more content…
So according to Zhao, Liu, and Deng (2005), agriculture exploits almost 70 percent of freshwater available in China, and there is an expectation that this quantity will grow because of the increase of world food production. Chinese people need a comprehensive scientific approach with long-term, coordinated efforts to solve this serious problem. So the first possible solution is recycling water in order to meet environmental needs, provide an additional source of water and have sustainable development and a viable economy. For this approach the Chinese Government needs advanced technologies that clean the water properly and also huge investment, so this would lead to having a big impact on economic development of the country. However, according to Chang (2009), the water which has been recycled is an essential resource of water for “non-potable”(not for drinking) uses in China and this water can be used for flushing toilets, car washing, agricultural irrigation, fire fighting, landscape irrigation, industrial processes and street washing. But one major disadvantage of this approach is that after water recycling there is no proof of that this water is clean enough for reusing it. For example, there might be quite an amount of pollutants, such as some chemicals, bacteria, even heavy metals and organic compounds (Wang, 1989). So as consequences, there
The Water Crisis and Solutions Essay

There is a global shortage of drinking water. A person might wonder how this can be if seventy percent of the earth’s surface is covered by water. Most of the Earth’s water is unsuitable for human consuption. Ocean water is salt water, which makes up 97.5% of all water on the planet. Freshwater is only 3.5% of all the water on Earth. Drinking water is sourced from bodies of freshwater.
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster…show more content…
Instead of increasing the supply of water to meet demand, a more viable method of addressing the water crisis is to manage consumption. The world population continues to grow, and trying to increase the supply of water is risky at best and usually costs exorbitant amounts of money, making this option available only to wealthy or economically developed countries. Therefore, controlling the use of water in municipalities or having a national policy of water conservation would allow the world’s supply of freshwater to better sustain itself through rainfall and other methods. Conserving water also saves energy, and energy is needed to treat, transport, and heat freshwater.
For water-saving programs to succeed, however, several things must be in place. The water saving program implemented by the city of Zaragoza in Spain highlights some basic actions required for such a program to succeed. Firstly, “rather than being a collection of fragmented, individual initiatives, the setting up of the Zaragoza Water Commission allowed the effective coordination of consultation, implementation and evaluation of different activities, with the aim of achieving a common goal.” (Water demand management, 2010) Secondly, the goal of reducing water use by all types of consumers requires the cooperation of a wide range of stakeholders. Working closely with stakeholder representatives allows the identification of realistic and acceptable water
