Gravity Recovery and Climate Experiment also known as GRACE has done some serious work about the Earth’s groundwater. As the global temperatures are rising, people are forced to pump out more ground waters due to high evaporation rate of the surface water. India, the second most populated country on planet has been at the top of ground water loss list.
The Indus basin is known as world’s largest groundwater source. Spread around the plains of India and Pakistan, this basin provides water to large section of people and supports agriculture which feeds the same. The millions of people are using ground water irresponsibly and pressure on this system is constantly increasing. GRACE satellites’ data was used by the University of California, Irvine to publish these findings.
Increased human consumption is biggest reason behind the ground water depletion, according to the report. The soil or deeper rock in the Earth’s crusts protects and stores water from the rains within the surface. This storage keeps area cool and green during summers or whenever there is absence of rains. World’s driest areas like desserts host some of the important sources of ground water. The life of the local population is dependent on these waters.
The socio-economic and political tensions will increase if water becomes less in these areas. We can already see India-Pakistan tension over the Indus Water treaty. In order to protect the lives of local populations, large scale water management techniques needs to be implemented. Water provider to 60 million people, the Arabian Aquifer system is most burdened in the world.
