Out of Africa – Did the Colonial Powers ever Really Leave?

Out of Africa – Did the Colonial Powers ever Really Leave? | Geography 200 | Scoop.it
Africa may have achieved independence, but the old colonial ties are still important as France’s decision to send troops to Mali to fight Islamist extremists shows.

Elizabeth Bitgood's insight:

This infographic was very interesting.  By using color coding it highlights the areas of influence the colonel powers still maintain over their old possessions.  This map is helpful in understanding how this affects the politics of theses regions today.

Colony powers are still located within Africa. Just because Africa is technically independent doesn't mean that British Colonial power isn't still in place.

This article reminds us all of the growth-stunt that colonialism in Africa brought to the continent.  It is not surprising to see that most African countries still depend heavily on their old colonial masters for survival.  People who may casually follow African politics might think that colonialism started with the Berlin Conference and ended in 1990 or so, but one could argue that it hasn't ended due to the urgent dependency African countries still have on their old colonizers.  Africa might be the most beautiful continent in the world but has the worst story of any in the world.

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.

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.

(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.

Similar to the Aral Sea,  the Tigris and Euphrates river basins have become drier and drier between 2003 and 2009. It is important to see all the aspects that have caused the rive to dry out and its do to there own people in this region. About 60 percent of the loss was attributed to the pumping of groundwater from underground reservoirs. Most of the problems are due to that about one-fifth of the water losses came from snowpack shrinking and soil drying up, partly in response to a 2007 drought. These could be some of the environmental issues but also there has been tremendous population increases in this region. This water is perfect drinking water for the people of South East Asia and the countries surrounding it but numbers are extremely high. 

It is important to analyze how us humans can change the geography of a certain area in such little time.

The middle east has lost a huge portion of its freshwater over the past decade. The two natural-color images above were acquired by the Landsat satellites and show the shrinking of the Qadisiyah Reservoir in Iraq between September 7, 2006 and September 15, 2009. The first graph shows the elevation of the water in that reservoir between January 2003 and December 2009. The second graph shows water storage from January 2003 to December 2009. Obtaining ground data information in the middle east can be difficult.The researchers calculated that about one-fifth of the water losses in their Tigris-Euphrates study region came from snowpack shrinking and soil drying up, partly in response to a 2007 drought.
