More than 4 billion people around the world have at least one month in a serious shortage of water resources per year, the affected population accounted for 2/3 of the total global population, showing the global water shortage situation is more severe than expected.
The scientific development of the United States journal recently published a new research report, which analyses the global water shortage on a monthly basis.
The report also noted that about five hundred million of the world’s population is two times the amount of water they live in the region throughout the year, which means that a sharp decline in groundwater levels, the survival of a large population becomes precarious.
The monthly new study of human habitation around within about 50 kilometers of water resources analysis, covering the decade data from 1996 to 2005, who used water is more than twice the supply of water is defined as a serious shortage of water resources.
Analysts said after a number of research reports prediction, the global water shortage affects population ranged from 17 million to 31 billion, the latest research has revealed that a population of more than 40 billion in the year with at least a month will face the serious shortage of water resources. The global water shortage problem is more serious than the original, with the increasing of the population and the rising of the water consumption, the water shortage crisis is bound to deteriorate further.
