    It is commonly accepted by many that the world faces a crisis over restrictions on water supply and we cannot continue to expect water to be a finite resource. According to A. Kirby (2000), the earth is covered by water in approximately two thirds of its surface. However, the vast majority of this water is too salty to use and, alarmingly, there is only 2.5% of it available for consumption by the human species. Furthermore, two thirds of that small percentage is locked in the icecaps and glaciers and with only 0.08% of supply accessible a picture begins to emerge of the challenges facing the world. Humans utilise approximately 70% of its water supply in developing its agriculture and related activities but the World Water Council has stated that it believes this figure could rise by up to 17% by the end of 2020. It could be argued that in ten years time millions of lives could be at risk because of the careless nature of our attitude to the production, treatment and consumption of water. Even in the present day it is estimated that approximately 30,000 children in poor and third world countries are dying each year from diseases directly related to the transfer and storage of water. The world’s water shortage issues have arisen because of the people who live in it, the rise in their population but most importantly their waste of this product. Overpopulation is another problem which causes water shortages.…

    With these solutions, water can be conserved efficiently because for the first method, it’s easy enough to do as an individual. Also for the second method which were about “shade balls”, it will make a great difference in saving water because if it didn’t exist, then the droughts would’ve gotten worse making it harder to live in those conditions. And finally for desalination, it is a great method for giving access to clean water. These methods have shown that if used, then the water that is left in our world may actually be saved if we took it to our…

    Water is an essential source of life, but there are categories of water which includes fresh or salt water. Most of earth’s land roaming animals needs fresh water for survival, including 6.7 billion people and their crops. The lack of fresh water makes a chain reaction of bad factors like illness, bad crops and unsanitary living conditions. Without water people cannot water their crops which leads to hunger, then bad health, and soon after illnesses that prevents them from working and going to school. It is easy to see why water is treated as an economic good because it has to be collected, managed, processed and supplied; it is a very expensive process that water goes through before it is clean and can be giving out to people to drink.…

    Everything which lives needs water to survive. There are a lot of places in the world where we can find such problem as lack of clean water, and most of these places are developing countries. These include areas in the north of China, India, and the western United States. Global climate change only exacerbates the problem of water shortage. The World population is currently 7 billion people, and each of them needs at least a liter of water a day. What is more, with the explosive growth of the world population, water scarcity is becoming more noticeably. Comprising over 80 percent of the earth surface and over 66 percent of human body, water will be the most important resource in the whole world forever. If oil, gas and coal will be enough humanity for 50-100 years, clean drinking water will end much earlier. Clean water is continuously renewed resource, but at the same time, it has come to an end. Dirty water is the cause of 80 percent of diseases in third world countries (Clarke, 1991). Likewise due to lack of water people on the earth will simply have nothing to eat, such as one kilogram figs need 2500 liters of water, and for the normal development of 1 hectare of wheat requires not less than 2000 liters of water. A lot of water is used not only for dinking, but for agriculture (around 90 percent). The purpose of this report is to determine feasibility of different techniques how to deliver or get clean water in arid regions of the world by the example of North Africa.…

    An important aim of water use in dry places can be stated in terms of maximization of the product or revenue obtained from that water use. What is to be maximized is the social benefit from the water used and not the quantity of water used itself. The economic concept also base on the economic value of water comes from the many uses to which water can be put in satisfying people’s needs. Water can have a very high economic value because it is scarce and because it is capable of being applied to many different uses. As a consumer good in ordinary households, water is needed first to drink, then for cooking, then for toilets and bathing, then for cleaning things like clothes and dishes, next for washing cars and driveways, and finally, in dry regions, for landscape irrigation.
