Global Reasons of Water Shortages Global Reasons of Water Shortages Water shortage is the world’s greatest challenge today. Shortage of water affects all continents with an estimated 3 million people lacking access to safe drinking water (Cech, 2010). Water shortages are caused by a number of factors with the major causes being climate change that has contributed to altered weather patterns leading to floods and drought, escalated pollution, increased demand for water and misuse of the obtainable water (Chamberlain, 2008). Other reasons for water shortage include environmental degradation such as deforestation for human settlement and wastage. These reasons in conjunction with uncontrolled population have led to straining of the available water sources limiting access to the resource.
Generally, water scarcity is caused by the growing demand for fresh water and depletion of the already strained water sources as people clear and settles on land near water catchment areas (Chellaney, 2013). In essence, such scarcities arise out of two mechanisms; absolute insufficiency and economic inadequacy. Physical insufficiency is attributed to insufficient natural sources of water as demanded by the dependent population. On the other hand, economic water shortages entail unsustainable management of the scarce water resources. This is the major cause of water shortage in developing countries. As earlier mentioned, climate change being one of the major reasons for water shortage in the world contribute to waning glaciers, condensed steam and shrinking lakes (Miller & Spoolman, 2009). There is an increasing need for global leaders to control global warming, pollution and environmental conservation if the problem of water scarcity is to be fully addressed.

Water shortages at Jordan

...Water Shortage in Jordan Water Shortage in Jordan People cannot survive without water; it is the reason why water shortage is a threatening issue in many world countries including Jordan. According to the official government resource, Jordan is a water-poor country because the supply of water is less than 1000 cubic meters per capita. In 1996, the consumption of water in Jordan equaled 170 cubic meters per capita which was far below the norm (Jordans Water Shortage, 1998). Growing populating and naturally hot climate challenge people and motivate them to find an effective model of water supply and consumption to make sure that the country can function event in such difficult natural conditions.

Global Water Crisis

...is not physically accessible by human beings. In fact, UNEP (2010) estimates that two-thirds of fresh water is tucked in frozen glaciers, meaning, it is not readily available for human and animals consumption, as well as for agriculture. In terms of accessibility, UNEP (2010) posits that approximately 1.1 billion people lack access to water, and a further 2.7 billion experience water scarcity at least a month annually. The World Bank estimates that 80 countries experience water shortages, translating to 2 billion people lacking access to clean water. One of the factors that has contributed to the global...
