Recommended: Solutions for water scarcity

Water is an essential for human beings and their healthy living. The total volume of water on Earth is about 1.4 billion cubic meters. km, of which only 2.5 % , or about 35 million cubic meters. km , is a fresh water . Most of the fresh water reserves are concentrated in the multi-year ice and snow of Antarctica and Greenland. This is why the problem of water is becoming increasingly important every year. These problems arising from droughts and floods, water quality degradation, poor management of water resources; inability to mitigate or adapt to climate change; the increasing number of extreme weather situations as well as the food crises, which are often associated with a lack of water resources. The Water Project stated that 80% of illnesses in arid regions are linked to poor water conditions. 1 out of every 5 …show more content…

This allows the most efficient way to absorb the wealth of the ocean water. Desalination of salt water is perspective because a large numbers of arid areas adjacent to ocean coast, or are close to it. Thus, ocean and sea water are raw materials for industrial use. Nowadays exist about 30 ways to of desalination of sea water. All methods of turning salt water into fresh water require more energy. In general, the share of electricity accounts for about half of the cost of desalination, the other half goes to the maintenance and depreciation of equipment. So, the cost of desalinated water depends mainly on the cost of electricity. (FWR, 2011) However, where is a lack of fresh water and exist the conditions for the desalination the cost factor recedes into the background. In some areas desalination is environmentally advantageous than bringing water from far away. Desalination of salt water is developing quite rapidly. As a result, every two or three years, the total capacity of installations

    Presently, in the USA the California state is starting suffer with water crises. Therefore, the state started planning many desalination plants. There are three current desalination station, and the government is planning more fifteen. Figure 9 shows the desalinations plants in the California state. There are many critics about the desalinization plants.20 Arguments use against the plants are which use huge amounts of energy, and is very danger for the marine life.20 Desalinated water construction costs approximately $2,000 an acre foot.20 In addition, to produce one gallon of drinking water need two gallons of seawater.20 This process consumes about 38 megawatts to remove 100 million gallons of seawater per day.20

    The water that they don't use and all of the salt goes back into the water. For example, ¨The second problem with desalination is discharging water. It is water that is released back into the ocean. Desalination typically uses two times more seawater than it produces in freshwater. To make 50 million gallons of fresh water, Carlsbad will need to draw in 100 million gallons of seawater. The leftover water will be returned to the ocean. However, it will not go back the way it came in: It will be much saltier. Normally, returned ocean water is twice as salty as when it was pulled in.¨ This shows that he water will not mix well with other water so the desalination should not be

    Desalinating ocean water seems like it would be too costly and impractical but the difference in cost between fresh water and desalinated water is minimal when you look at the benefits that come along with being able to use ocean water. As of 2008, the price of fresh water ranged anywhere from ten to twenty cents per cubic meter and the price of desalinated water ranged from around one to two dollars per cubic meter. At first you see that the cost is nearly ten to twenty times greater for desalinated water but by using desalinated water not only are you conserving fresh water but you could also potentially curb the problem of sea levels

  • The Water Crisis and Solutions

    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 for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.

    The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.

    Freshwater in the world makes up only a small portion of water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only <1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.
