Here are some important causes of water shortage:
According to a number of studies, with less than three percent of the world's water now acceptable for human use, the impact of a water shortage from the climate change could be catastrophic. The question is if enough preparations are being made for such an occurrence.
Between andthe consumption of water climbed sixfold, or over two times the rate of population growth Anderson, The United Nation estimates that byfive billion of the world's expected 8 billion people will lack access to safe water Funk, In fact, at current usage rates, Delhi, India, will run out of groundwater by Anderson, Groundwater only adds up 0.
Since the annual supply of renewable fresh water remains relatively constant, the amount of water available per person will continue to decrease substantially along with the quickly rising population and associated environmental degradation.
Water scarcity worldwide that may reach crisis proportions in a matter of years. Many believe this is a Third World problem. The most critical shortages will be outside of the U. Water sources in the U. Aquifers here are draining more quickly than they can be replenished, and the largest one, which is called Ogallala and stretches from the states of Florida water shortage essay Dakota to Texas, has recorded localized dips in the water table of feet.
In addition, seven states in the West are attempting to get more water from the drought-ridden Colorado River, which is already reduced to 0. Rapidly increasing cities throughout the Southwest and West, such as Los Angeles, San Diego, Phoenix, and Las Vegas, have reported numerous droughts and stretched their water supplies to capacity and beyond McKenzie, For example, researchers at the Scripps Institution of Oceanography at the University of California, San Diego, and the University of Washington state that global warming will reduce glaciers and storage packs of snow in worldwide areas and impact millions of people.
Human-produced greenhouse gases, and the warmer climates that result, will significantly affect ice and snow-dependent regions and lead to major disruptions to water supply and resource management systems.
Based on researchers' findings, the forces leading to the warming trend will cause more water to fall as rain than as snow, which will fill reservoirs to capacity earlier than normal.
This change in climate will also lead to snow melting in earlier months than in prior decades and disrupt the usual timing of accessible water from snow runoff of streams. For instance, hydrological simulations in Europe warn that climate warming in the Rhine River Basin may reduce peak-demand water availability for manufacturing production, agriculture and consumer uses.
As a result, ship transportation, flood protection and hydropower generation could be threatened Sea Technology, Mohamed Dahab recently went to Stockholm Water Week session in Sweden and participated in "arguably one of the most diverse global water forums.
Stockholm Water Week examines the world's water situation with special emphasis on water supply and sanitation. It reviews the progress toward solutions and the commitment to sustaining the water environment within a global setting. Experimentation in several areas is taking place. However, all of these solutions have their price.
Desalination, for example, is very costly. The country's first large-scale seawater plant, a MGD facility that was having operational difficulties, finally began operations in Tampa, Florida.
As many as 20 desalination projects along the coast in California will be debated. Normally high-electricity consumption desalination plants are starting to become more economically feasible because of technological advances in water-purifying reverse-osmosis membranes, which are contained in a large plant by the thousands.
The newest can produce upward of 10, gallons a day, or an increase from 5, gallons in the late s. Composite materials may soon double a membrane's life, from five to ten years, and nanotube-based membranes will shorten the length each water molecule must travel.
They wonder if the cost and environmental effects, including the marine kills during intake and discharges of hyper-saline brine, are worth the expense and instead look at reclamation and reuse.
George Tchobanoglous, professor emeritus of civil and environmental engineering at University of California Davis, adds. But the focus must be on reclamation and reuse. Already, worldwide development is taking place where there is a lack of a natural water supply.
To sustain that development and bring peace to these areas of the world, reclaimed water may be the solution Funk,p. However, experts recognize the many barriers that face the use of reclaimed wastewater.
For example, public perception issues must be addressed. However, the present perception is if it was once wastewater, it is dirty Anderson, Water collected from roofs and stored underground can also be of considerable help: For instance, the airport terminal in Frankfurt, Germany, annually captures 16 million liters of rain on its roof and uses it for cleaning, gardening and toilets.
Water resources will also need integrated into the solution of people's social, economic, and health needs. Better water-management techniques include conserving supplies by repairing underground pipes, using more-economical methods of irrigation, and installing water-saving appliances Coles, Reason #4: Conserving water can also save energy..
In order to pump the water from a central facility into your home or office, energy is required to run that equipment. For example, studies have shown that in California alone, percent of all energy consumed goes towards moving water .

The California Drought Who Gets The Water And Who's Hung Out To Dry? Editor's Note: The California State Climatologist has noted that while El Niño rains will help the state, which is in its fifth year of drought, the water storage in long-term reservoirs remains below normal levels.
