Fresh Water
1. Introduction

Fresh water is an indispensable resource for human livelihood, agricultural irrigation and economic development (Brooks, 2007). However, due to the rapid population growth and the limited reserves, increasing regions have faced serious scarcity of fresh water (Williamson, 2010). Saudi Arabia is one of the driest countries in the world (CIA, 2011). According to World Bank (2011), the world average fresh water consumption is nearly 7000m³/year/person, while the water resource per capita in Saudi Arabia is less than 1200m³/year/person. In order to satisfy the demand for water, Saudi Arabia currently supplies fresh water via deep drilling of fossil groundwater (UNESCO, 2009). Nevertheless, society increasingly recognises that those water resources are non-renewable and are liable to be reduced by the overexploited boreholes and wells. Thus Saudi Arabia needs to find alternative and sustainable methods to solve these issues. Since there is abundant sea water around Saudi Arabia, large-scale desalination could be the ideal solution to water scarcity. However, the expensive cost and the detrimental influence on the environment might limit the scale and sustainability of this method. Due to the cheap cost and the minor environmental damage, wastewater reuse is regarded as another potential solution. However, it seems to have a low social acceptance.

Therefore, this report will compare the feasibility of desalination and water reuse in terms of cost, social acceptance and environmental impacts, thereby exploring the most suitable method to deal with the scarcity of water in Saudi Arabia.

2. Background

Saudi Arabia is located in the Middle East, bordering the Persian Gulf and the Red Sea (CIA, 2011). It is famous for the abundant reserves of oil and gas. However, the fresh water resources in Saudi Arabia are very limited. According to World Bank (2011), there is no one river and lake with perennial water throughout this country.

    Water is the most valuable and indispensable resource for all forms of life. People need it for every activity: domestic use, agriculture and industry. Access to fresh water is regarded as a universal human right (United Nations Committee in Economics, Social and Cultural Rights, 2003). Drought has become an increasingly important problem in many parts of the world. Water scarcity is most common in arid and semiarid regions of the world, which cover one third of the Earth’s land surface (Smallwood, 2011). UNESCO and the Italian Ministry for the Environment and Territory (IMET) have launched “The Water Programme for Africa, Arid and Water Scarce Zones”, which seeks to develop the potential management of water resources to protect the fragile environment of water scarce regions. Additionally, limited fresh water resources available in these regions are also threatened with deterioration in quality due to hydrological changes. The accessible water in arid regions are often restricted to groundwater. Surface flows are usually limited to flash floods due to short duration and high intensity rainfall events. The purpose of this report to describe the feasibility of different techniques for providing fresh water to arid region, like Africa. Firstly, this report will consider the background to this problem and then it will compare and analyze two water provision methods in Africa, desalination and dams. Finally, this report will offer some recommendations.…

    Access to clean water is considered a basic human right and in many countries when sustainable development is considered, water is at the top of the list of priorities (Omer, 2008). The value of water is increasingly felt in areas such as Sudan, where precipitation is inadequate while temperatures are high resulting in dry or arid conditions (Food and Agriculture Organisation (FAO), cited in USAID, 2010). Two-thirds of the country is arid and rainfall is less than 400mm annually. Regardless of the fact that about 60% of Sudan lies within the Nile basin, it only draws 18.5x109 m3 from the Nile’s annual flow of 84x109m3 and added to its internal supply of 12x109m3, the water availability falls considerably below the water stress limit of 1000m3 per head (ibid).…

    Two years ago, when I was in high school, our social science teacher told us there had a serious drought in Southern California. Most of us did not know anything about it and we felt so surprised about this new. Today, when I heard this new again, I can’t believe that the drought still exist in Southern California, I thought it already solved by the government because it had been two years when I heard this new. From most of my research, it said that it had been fourth year for California to have the drought. Water supply is no longer enough in California, our government was trying to think a best useful way to solve this problem. Some people think that desalination is a good solution because it cost less money and can also recycle the energy.…

    Egypt is particularly destitute of water because the majority of these regions are extremely arid. According to Peel et al. (2007, p.1638), the climate of Egypt is hot desert climate. In other words rainfall is quite rare in these regions and the evaporation of water is serious due to high temperature. Furthermore, the increasing population make the water supply for Egypt bear more stress. As illustrated by the data from Engelman and LeRoy (1993,pp.55-56), the regional average per capital water availability was 2385 m3/year in 1995 after which it sharply descended to 1046 m3/year in 1990 and is excepted to be keeping declining to 676 m3/year by 2025. Generally, lacking of water has been the most obstacles for Egypt to support the society and develop the economy. Thus, it is of great significance to explore the suitable water provision methods to meet the increasing water demand of Egypt.…

    Fracking Water Shortage

    Aquifers are being depleted at an increasing rate and our water tables are sinking. We must reduce our water usage, while still maintaining our human needs. Fracking must be stopped, not only does it pollute people's drinking water, it also depletes our aquifers. When fracking occurs water is forced way below our water tables, never to be accessed again. IN this age we cannot afford to waste water in that way. Countries living in desert-like conditions should not expand their agriculture. Expanding to the desert will allow for a short time for those countries to be less depend upon others for food sources. However, the aquifers will be depleted and there will be a lack of food left. Countries in areas with water shortages will have to find ways to either farm with minimum water or seek outside assistance. We need to invest in more reach in desalinization. At the moment desalinization is a very expensive option that water companies are beginning to invest in. Governments in countries with few water resources should invest in these practices, even if it is expensive. Running out of water should not be an option. They should invest in more rainwater collection. We need to readdress how we look at the water. It is not necessarily a never ending cycle of harmony, we must invest in…

    According to Talbot, there are currently around 16,000 desalination plants in the world (2014). Although a con to this method involves needing a lot of energy, the benefit in having these desalination plants is that it gives saline or salt water a better purpose rather than it being an undrinkable source. Also, it helps countries that do not have a lot of access of large bodies of freshwater and rainwater, such as Saudi Arabia, Kuwait, and Algeria. The method is now being adapted into the U.S. in order to fix problems such as the recent California drought.…

    During the last few decades, the development of new and efficient technologies has opened the possibility to use desalination at larger scales than previously used. Currently, many countries have already installed desalination plants, and for some places it constitutes their main water source. In the United States, severe and extended droughts in California led the government to search for alternative water sources; and thus, it inspired the development of a desalination project to help satisfy the state’s water demands. The Carlsbad desalination water plant is the largest plant in the western hemisphere; nevertheless, besides the overwhelming support from the inhabitants of the state and the authorities, there is still many controversy on the actual benefits from its…

    While desalination sounds like a great way to solve the world’s water issues, there are many problems related to the sustainability of this process. Obviously, as discussed earlier, desalination has many negative impacts on the marine environment, but there are as well other reasons that it is not sustainable. For instance, desalination requires a very high-energy demand, which contributes to the reliance on fossil fuels and therefore the emission of pollutants such as greenhouse gasses. On average desalination requires 15,000 kWh per million gallons. Compare that to a modest 500 kWh per million gallons on average for traditional water treatment (Cooley 2013). The burning of large amounts of fossil fuels to desalinate water, and as a consequence…
