While we are talking about access to water for maybe millions of people in India or for a billion people around the world, the sad story doesn’t just end there.
If a deep dive into the past can make mankind retain the natural resources just the way they are, that would have been phenomenal. But, we do have a little say about it.
Right to consumption. Rightful to conserve.
Fresh water across the world is depleting and is racing towards danger levels. A recent study by NASA indicated that Northern and Eastern parts of India is in the hotspot. It also mentioned that wet lands in the country are getting wetter and dry lands are getting drier. The result is because of the drastic change of climatic conditions and nature cycles.
Gravity Recovery and Climate Experiment (GRACE) with a first of its kind study used 14 years of observations to find the actual difference in the decline of fresh-water in the country.
“This is the first time that we’ve used observations from multiple satellites in a thorough assessment of how freshwater availability is changing, everywhere on Earth,” said Matt Rodell of NASA’s Goddard Space Flight Center in Greenbelt, Maryland,
“A key goal was to distinguish shifts in terrestrial water storage caused by natural variability – wet periods and dry periods associated with El Nino and La Nina, for example – from trends related to climate change or human impacts, like pumping groundwater out of an aquifer faster than it is replenished,” Rodell added.
It was once believed that water from lakes, rivers and ground-water are fresh and ready to use for drinking and agriculture. But, it is not the same case anymore. There are areas where the fresh-water availability is relatively stable, but in some areas it either go up or decline. There is no in-between.
“What we are witnessing is major hydrologic change,” said co-author Jay Famiglietti of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
“We see a distinctive pattern of the wet land areas of the world getting wetter – those are the high latitudes and the tropics – and the dry areas in between getting dryer. Embedded within the dry areas we see multiple hotspots resulting from groundwater depletion,” Famiglietti warned.

Though observations couldn’t possibly tell the reason behind the inconsistent trends, mankind is to be blamed for taking the resources for granted.
Is it too late for us to reconsider our usage pattern towards water resources?
