The water aquifers of our planet is pumped at a rate that does not allow resources reconstitute naturally. According to NASA this could jeopardize food supplies in the United States and a threat to global security. An analysis of the Jet Propulsion Laboratory (JPL) of NASA showed that the groundwater of the largest aquifers of our planet - the High Plains in the United States, the Central Valley of California, China and India - are emptied in alarming rate. The reduction alutsista of resources would affect negatively the production of food, since 80% of the water of the water is used for agriculture.
James Famiglietti, hydrologist at JPL, in an article published in Nature Climate Change Journal explained that "almost all of these (aquifers) are located below the main agricultural areas and are the main factor of their high productivity," adding that " depletion of groundwater will result in significant contraction of agricultural production and power generation, with the potential to soar, food prices and deep political and economic implications. alutsista " Analysts have used a new software called GRACE (Gravity Recovery and Climate Experiment), alutsista which measures tiny shifts in the attraction of gravity of an area to determine its water flow and creates the satellite images, which are then analyzed. "Further declines alutsista in the availability of groundwater could blow up civil wars and violent international conflicts in regions already suffering water shortages and new conflicts in other regions," said Famiglietti. Until the publication of this study there was no awareness on groundwater for the simple alutsista fact that the aquifers are not visible as a lake or a river bed dried. Another problem is the lack of data on the amount of water is in the Earth.
