Need help with my writing homework on Fresh Water Provision Techniques in Arid Regions. Write a 1500 word paper answering; To make matters worse, the little water received in these areas is usually not safe for domestic, agriculture, and commercial use, and there an urgent need to provide fresh water. Policymakers explore various freshwater provision techniques, as discussed in subsequent sections of this report.  .
In endeavors to provide fresh water to the world's arid regions, different techniques are employed that include ground water drilling, desalinization, and piping techniques. These techniques often vary from those employed in areas where precipitation is high. Therefore, climatic conditions in arid regions dictate to a large extent what technique(s) is most appropriate. Key issues in water provision and water resource management, which dictate appropriate techniques, will include the availability of adequate supply, conservation measures, cost-effectiveness, pricing, and sustainability. .  .
Groundwater is normally obtained from aquifers through drilling and piping the water to the surface for various uses. This technique involves identifying areas in arid regions that have sufficient and quality underground water for agriculture, domestic, and commercial use. The technique is more preferred to its low cost of establishment compared to other techniques like desalination. To ensure sustainable use of underground water, policymakers and regulatory authorities establish water databases by registering wells and their yields, documenting water composition, controlling drilling in all phases, and regular monitoring of water table and salinity changes. However, this technique's challenge is that over time demand for fresh water has increased both socially and economically, requiring more wells to be dug.
For example, over the last three decades, demand for water within the United Arab Emirates and other Gulf states, which are often classified as arid regions, was estimated to increase from 4,250Mm3/ year in 1980 to 35,395Mm3/ year by 2010 (Alsharhan et al. 2001, 277). Therefore, this means that governments in arid regions have to drill more wells or explore alternative freshwater supply techniques.  .
