Among the major challenges that have continued to threaten the existence of man on planet earth is the decreasing availability of water. Water resources are now being used for generating electricity and manufacturing industrial products among other uses that have recently emerged (Business Council of Australia 2011). Rainfall remains the major source of fresh water. Regions that receive adequate rainfall are often rich in water resources. Often, such regions produce high agricultural yields, and have abundant fresh water sources such as rivers and lakes. On the other hand, regions that receive very low rainfall (such as deserts) have scarce water resources (IBG 2011). With an average annual rainfall that falls below 200mm, deserts are the driest regions on our planet. Due to scarcity of rainfall, Africa, Saudi Arabia, and Australia are among the regions on our planet that have been hit by a recurring problem of water scarcity (Royal Geographical Society 2008).

A negative effect of climate change is a decrease in the amount of available precipitation. Usually, precipitation is often reduced as a result of decreasing rainfall and increasing temperatures. Sadly, like most other parts of the world, the trend in Africa, Australia, and Arabia has been a decrease in rainfall and an increase in temperatures. Diagram 1.1 shows how surface temperatures have been rising at Lake Tanganyika; an indication of rising temperatures in the region. Here, droughts are now increasingly common; hence, resulting in water shortage. Such a direction has been observed in worst affected regions like Ethiopia in Africa. Here, temperatures have been increasing by an average of about four degrees in the past decades. Lake Tanganyika, East Africa Source: UNDP Generally, deserts (like the Sahara) have been increasing in size over the years. The current trend where the ice caps of major mountains like Mt.

Other useful approaches that can be employed to tackle the problem of water shortage include employing water recycling techniques and desalination of sea water (Shaw 2008). So as to stem the water scarcity challenge in Africa, Saudi Arabia and Australia, a good management policy is required. While some of the measures that can be undertaken to tackle the water challenges here are required to operate at the local level within the areas that have been affected, some of the measures that are needed will require an integrated global approach. While measures like planting of trees and cleaning of rivers require a more local based approach, tackling the challenge of greenhouse effect (as it was realised in the Kyoto protocol) requires an integrated global approach.

Syria, Iraq, Lebanon) have reliable sources of surface water; the majority, however, depend either on groundwater or on desalination for their water supply, both of which enable them to use water in amounts far exceeding the estimated renewable fresh water in the country.” .“Yet water scarcity will be at the forefront of the international agenda for decades to come.Gaining potable water through desalination is already a great source of water supply for many countries as Saudi Arabia but it is constraint by its high cost.Water scarcity has also high influence on industrial development.In very dry years an overexploitation of the water resources was observed with the cause that the sea water table reaches already a critical value.
In Egypt alone, water levels in the Nile River have declined by nearly 200 feet because of increased water use, causing increased withdrawals from the Nubian Sandstone aquifer.Over the past 4 years, there have been cases where the solutions used to water the plants which also contain minerals as well as chemicals for the plants growth, have contaminated nearly 25% of the shallow waters used not only for drinking water, but again used for agricultural farming methods.The International Water Management Institute estimated in 2010 that by 2025, Egypt and Libya will suffer from physical water scarcity where the water used will exceed 60% of its usable supplies, and Chad and Sudan will have severe economic water scarcity.These are some of the...
Many researches indicate that water transfer can meet the huge water demand which will promote both industrial and agricultural developments (Lorang and Aggett, 2005).However, 2.5 % of fresh water are unusable while another 0.497 % is polluted water, only 0.003 % of the whole water on earth is available for drinking water.It is known that 70 % of the earth’s surface is covered by water but 97% of this is saltwater and the other 3 % is fresh water that consists of surface and ground water.If an arid region is short of sufficient water resources but with the strong economic capability, it should own a large scale of the water transfer project as it may meet the huge industry and agriculture demand.In conclusion, it appears that arid region...
