Write a report assessing the feasibility of different techniques for providing fresh water to arid regions of the world - Essay Example 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. Due to this shortage, these regions face difficulties in not only economic development but also human resources development, with people living there facing numerous struggles. Thus focusing on the current tough situation in arid regions, and the resultant difficulties, this report will discuss about two different water provision techniques of desalination and water transfer, and how they can provide fresh water to those regions. Although, 70 percent of the Earthââ¬â¢s surface consists of water, only around 2.5 percent is fresh water, with the rest being salt water contained in the oceans. (ââ¬Å"And not a drop to drink?â⬠, n. d). Among the already minimal proportion of fresh water, just about 1 percent is easily accessible for the people to ââ¬Ëtapââ¬â¢ and utilize, and that 1 percent is found mainly in rivers, lakes as well as some underground sources. ââ¬Å"Only this amount is renewed regularly by rain and snowfall, and therefore available on a sustainable basis.â⬠(ââ¬Å"And not a drop to drink?â⬠, n. d). However, the key issue here, this 1 percent is not evenly distributed throughout the world, with arid regions bereft of those natural fresh water sources. ââ¬Å"The Amazon carries 16 percent of global river flow (or run-off). But arid zones, which cover 40 percent of the worlds landmass, have only 2 percent of run-off.â⬠(ââ¬Å"And not a drop to drink?â⬠, n. d). Co nsidering 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. Clarke
