Download file to see previous pages Arid regions of the world, found mainly in Africa and Middle-East Asia, typically lack physically accessible, hygienic, and adequate water supply, necessary for multiple aspects such as domestic use, industry and agriculture. Thus focusing on the current tough situation in arid regions, and the resultant difficulties, this report will discuss two different water provision techniques of desalination and water transfer, and how they can provide fresh water to those regions. Although, 70 per cent of the Earth’s surface consists of water, only around 2.5 per cent is fresh water, with the rest being salt water contained in the oceans. (“And not a drop to drink?”, n. d). Among the already minimal proportion of fresh water, just about 1 per cent is easily accessible for the people to ‘tap’ and utilize, and that 1 per cent is found mainly in rivers, lakes as well as some underground sources. “Only this amount is renewed regularly by rain and snowfall, and therefore available on a sustainable basis.” (“And not a drop to drink?”, n. d). However, the key issue here, this 1 per cent is not evenly distributed throughout the world, with arid regions bereft of those natural freshwater sources. “The Amazon carries 16 per cent of global river flow (or run-off). But arid zones, which cover 40 per cent of the world's landmass, have only 2 per cent of run-off.” (“And not a drop to drink?”, n. d). Considering these shortfalls, people living in these regions face drinking water shortage, deterioration of agricultural production as well as industrial activity. There are a variety of estimates concerning the amount of water humans need on a daily basis. ...Download file to see next pagesRead More

...in order for the water to be fresh. Conclusions The extraction of underground water is the most viable option, but will require the use of technology in the extraction of the salts present in the water to make it fresh. Underground water it the most available and is in the arid areas through oasis. When technology is incorporated, the water quality can be improved and lead to the development of success. Rain water harvesting could be the cheapest water provision technique, but the climatic conditions do not favour its use. There are no...

...to the ocean. With the increase in population and industrial growth, the demand for water is increasing day by day. According to Lenton and Muller (2009), around 780 million people do not have access to safe drinking water currently. They further state that 47% of the world’s population will be facing a serious water crisis by the year 2030 if proper measures are not put in place to conserve water. An arid area is defined as a region that is extremely dry and has little or no vegetation (Walton 2000). The main factors that affect aridity are temperature, evaporation rate and rainfall.

One of the options available is the construction of dams. On a smaller scale, we can have sand dams and the ground water dams (Borst and Haas, 2006) which are cheaper and do not require a lot of capital investment. Sand dams are built above into the riverbed of a...
