high intensity. (Most of the rain falls in just 100 hours out of 8‚760 hours in a year). Because of such short duration of heavy rain‚ most of the rain falling on the surface tends to flow away rapidly leaving very little for recharge of groundwater aquifers. Most of the traditional water harvesting systems in cities have been neglected and fallen into disuse‚ worsening the urban water scenario. Most of the Air Force Stations are situated in cities/towns which have acute water shortages. The case of

freshwater aquifer. Next‚ water with “fracking fluid” is injected into the drilled area to crack the shale. This water comes back up to the surface and is put into a pit to evaporate. The natural gas flows up‚ and is then stored. The process is simple enough‚ but so are the consequences. Hydraulic fracturing has detrimental environmental consequences and should be banned. As stated before‚ to get to the shale of gas‚ the drill passes through the fresh water aquifer. The aquifer is where the

shorter pipeline transporting oil has had twelve leaks in its one year. A longer pipeline raises serious concerns for environmentalists. In the state of Nebraska‚ the Ogallala Aquifer supplies water for agricultural purposes and to more than two million people. If a minor oil spill occurs in that area‚ ground water and the aquifers would be contaminated. While the building of the pipeline raises about 3500-4500 temporary jobs‚ this type of oil spill would kill hundreds of thousands of permanent jobs as

of ground water is eminent; such places include parts of Mexico‚ India‚ China‚ and the Middle East. Overpumping of groundwater leads to salt-water contamination and can make water undrinkable; this has happened in Florida‚ Turkey‚ and Bangkok. As aquifers lose water‚ their substrate can become weaker and less capable of supporting overlying strata‚ and the land surface above may subside. For this reason‚ cities from Venice to Bangkok to Beijing are slowly sinking. Mexico City’s downtown has sunk over

Water is our past. Water is our future. Without it‚ we cannot survive‚ and there are no alternatives. Many people have likened the issue of water scarcity to our current economic struggle over petroleum. Without petroleum‚ we can’t drive our cars‚ and maybe we have to walk to school or work. This is not the case for water‚ as we are not dealing with simple inconveniences (as grandiose as they may be)‚ we are dealing with the issue of sustaining life itself. The global lack of abundance of usable

Rain water harvesting is a technique of recharge of ground water by capturing and storing rain water. This is done by constructing special water-harvesting structures like dug wells‚ percolation‚ lagoon‚ check dams etc. Rain water harvesting is not only proving useful for poor and scantly rainfall regions but also for the rich ones. The annual average rainfall in India is 1‚200 mm. It is astonishing fact that Cherrapunji (Assam)‚ the place receiving the second highest rainfall is 11‚000 mm still

Over the last 50 years our water demand has tripled‚ which is causing water tables all over the world to fail‚ and when these aquifers are depleted‚ worldwide food production will fall. I have looked over the data provided‚ and have come to the conclusion‚ that if we do not control our population‚ we will likely experience worldwide famine‚ maybe even have it as the catalyst for
