Introduction Water is possibly among the most integral resources in the world. Water is one of the main resource for human development, it is even one of the major resources for agriculture, transportation and industrialisation. According to USGC (2015) about 70 percent of the earth is covered with water and from that only 2.5% is fresh water.Though water is an integral part of human life many people do not have access to it. The water (2015) claims that 663 million people or about 1 in 10 people in the world do not have access to fresh water. Industrialisation has aggravated water pollution and that has decreased the amount of freshwater available, one such example of a polluted fresh water river is the Chao Phraya River in Thailand (Greenpeace,2015). As freshwater bodies are becoming more scarce and expensive, fresh water should be provided in the most feasible way possible. This report will illustrate Desalination and Cloud seeding as the two techniques for providing fresh water in the arid regions of the world. Firstly, this report will look at the present situation of arid regions. Next, this report will examine the requirements needed for the techniques such as monetary and environmental requirements. Finally, comparisons would be made between the options and recommendations would be given. Background The Oxford dictionary (n.d) defines arid regions as those that have little or no rain.
