Global Water Crisis

Introduction: The current global population size is more than than three times what it used to be well-nigh carbon years ago. From about 1.6 billion in 1900, the population has grownup to 7 billion in 2012 ( commonwealth Reference Bureau 2011). Population growth, industrialization and urbanization come with increased pressure on piddle and other resources. As a result, the use of renewable water resources increased six-fold between the years 1900 and 2000 and will stick around to increase as the global population grows (World water supply Council 2012). Water famine is a cause for concern because water serves as a domestic and industrial resource, and habitat for aquatic organisms. or so one-seventh of the worlds population lacks access to faint water (Water.org) and a vast majority of such hoi polloi live in developing nations. Saskatchewan faces water shortage payable to the unpredictability and seasonality of water resources and water use in potash mining (Pomeroy et al, 2005).
System structure, function and human impact: Naturally, water is continuously being cycled through the environment the hydrological cycle. Water shortage arises because the rate of consumption exceeds the rate of natural replenishment. Human use has a profound effect on water availability.



Saskatchewans ten potash mines consume a total of about 10-15 million cubic metres of water on average per year (Reid, 1984). In the agricultural sector, water is mainly used for irrigation and bloodline rearing. Between 1990 and 2000, there was an exponential increase in the soma of irrigated hectares of land in Saskatchewan due to economic development (Government of Saskatchewan).
humor change is also a significant contributing factor. In the last century, the mean annual temperature in the prairies increased by about one degree Celsius or more in some areas (Saskatchewan Eco Network 2012). In Saskatchewan, the mean annual temperature is expect to increase by at least three degrees Celsius by the end of the 21st century...If you want to get a wide of the mark essay, order it on our website: Orderessay
