write a homework on Feasibility of Different Techniques for Providing Fresh Water to Arid Regions of the World. Write a 1250 word paper answering; Lack of vegetation can often be viewed in these areas and as observed there is a possibility that in the coming years these areas might turn out to be deserts. In addition, these areas witness about 700mm of rainfall in an annual basis and these areas are often subjected to periodic droughts and water shortage which have been the main concerns for the people living in these areas (International Institute for Sustainable Development, n.d.). In relation to these areas, it is very important to increase awareness about sustainable management related to water resources. Correspondingly, the essay intends to analyse the feasibility of various techniques used for providing fresh water to arid regions of the world.

Arid regions and the people living in these regions have been facing increased problems regarding water shortages due to which various techniques have been used in order to reduce the problem and provide fresh water to the people living in these areas. It is considered that programmes of sustainable development must be introduced in these areas that would create awareness amid people regarding the management of water resources as these places usually have an inadequate supply of underground water. Besides, the available freshwater in these areas has become salty as the aquifers in these regions are continuously getting destroyed. As it has been viewed that these areas have limited sources of water, therefore it is considered that various techniques must be used that would provide an adequate supply of freshwater. These techniques include desalination, treatment of wastewater and using boreholes to harvest groundwater.

Desalination: This process is also termed as distillation which involves changing salty water into fresh water by removing the salt that is mixed with seawater. It is the most ancient and common method of water treatment which is considered quite feasible for providing fresh water for the people living in arid regions as this process removes the impurities present in salt&nbsp.water.&nbsp.
