Challenges Of Saving Water Essay

Saving water is one of the most “talked about” topics when it comes to environmental crisis management. The water crisis is ranked as #1 global risk based on impact to society (as a measure of devastation), and ranked as #8 global risk based on likelihood (likelihood of occurring within 10 years) as announced by the World Economic Forum, January 2015. Approximately one in nine people lack access to safe water i.e., over 750 million people around the world, which is twice the population of the United States alone [1]. This fear of water scarcity has led the scientists to explore for traces of water beyond the Earth’s atmosphere and NASA recently managed to confirm an indirect evidence of transient liquid water at the Gale Crater on the planet Mars [2]. To understand why water saving is an urgent need, it is important to recall and realize the water distribution over the earth surface. Earth’s surface is

The per capita water consumption in UAE is 550 liters/day, which is way more than double the global national average of 250 liters/day. The total consumption has exceeded 24 times the natural recharge capacity whereas groundwater supply has fallen by 18% since 2003. In 2009, the total water demand in UAE was 4.5 billion m3 which was met by groundwater (72%), desalinated water (21%) and retreated water (7%). Water consumption in UAE is primarily divided among three sectors – Private households, Agriculture, and Industries. Private household sector accounts for about 24% of total water consumption in the UAE. One of the largest contributors to water consumption has been the use of air conditioning systems, because of high temperatures almost throughout the year. An air-conditioning system not only consumes large amounts of energy, but also uses large quantity of water via chilled water pumps
