Freshwater Stores Shrank in Tigris-Euphrates Basin

Freshwater Stores Shrank in Tigris-Euphrates Basin | Geography 200 | Scoop.it
An arid region grew even drier between 2003 and 2009 due to human consumption of water for drinking and agriculture.

Elizabeth Bitgood's insight:

The use of water is an increasing problem in the arid regions of the world.  The use of more sophisticated irrigation systems allow for more planting which requires more water.  Coupled with increasing towns and cities needing fresh water for the inhabitants this decrease in fresh water will only continue to trend.

Year 10 - Inland water

Amy Marques's curator insight, April 24, 12:52 PM

What's happening in the Tigris-Euphrates Basin is similar to what is happening to the Aral Sea. Freshwater Stores Shrank in just 4 years. Humans are drastically altering the landscape and if we don't start to find others ways of doing things and change the way in which we do agriculture and use our water, there could be a serious water shortage for millions of people.

(Southwest Asia topic 2)

The area known as the Cradle of Humanity is becoming less hospitable. Though natural climate change can be attributed to the dryer conditions, humans have made just as much of an impact. Increased water usage leads to less reserve. Impacts stretch further, however. Less water flow below the dam can lead to changes in sedimentation patterns and disrupt wildlife habitats, potentially causing harm to wildlife.

NASA Satellites Find Freshwater Losses in Middle East

NASA Satellites Find Freshwater Losses in Middle East | Geography 200 | Scoop.it
A new study using data from a pair of gravity-measuring NASA satellites finds that large parts of the arid Middle East region lost freshwater reserves rapidly during the past decade.

 

"[This] data show an alarming rate of decrease in total water storage in the Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India," said Jay Famiglietti, principal investigator of the study and a hydrologist and professor at UC Irvine. "The rate was especially striking after the 2007 drought. Meanwhile, demand for freshwater continues to rise, and the region does not coordinate its water management because of different interpretations of international laws."

Elizabeth Bitgood's insight:

Water is a big issue in an arid area.  The fact that we can measure the amount of groundwater present in an area with a satellite is amazing to me.  The issue of water rights and control in this region will someday over take that of oil rights and use in my opinion.  Once people get used to free flowing water to use on demand it will cause problems politically when these sources of ground water inevitably dry up.

This is a perfect example of geospatial technologies can lead to a better understanding of how the Earth's physical systems are changing because of human geography.  Teaching geography is about showing how these systems are interconnected.
