Really? Water is everywhere instead of people fighting able I think we should come to together and find a cheap, effective way to purify salt water with the ice caps melting and turning into salt water I think we should be looking into ways to convert salt water to fresh water

Gaza Water Confined & Contaminated | Visualizing Palestine

Gaza Water Confined & Contaminated | Visualizing Palestine | Walkerteach Geo | Scoop.it

Here is an interesting infographic that was posted to Flowing Data today.  It looks at water accessibility and quality issues in Gaza.  Very useful for highlighting the impact of conflict on basic human needs and natural resources.

Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | Walkerteach Geo | Scoop.it

By moving the slider, the user can compare 1990 false-color Landsat views (left) with recent true-color imagery (right). Humans are increasingly transforming Earth’s surface—through direct activities such as farming, mining, and building, and indirectly by altering its climate.


This interactive feature includes 12 places that have experienced significant change since 1990.  This is an user-friendly way to compare remote sensing images over time.  Pictured above is the Aral Sea, which is and under-the-radar environmental catastrophe in Central Asia that has its roots in the Soviet era's (mis)management policies.

Luke Walker's insight:

See how much the Aral Sea has changed due to the impact of humans on their environment for yourself. Drag the slider tool to see a before and after. Reference your textbook (p61) for the whole story.

Clearly the water level has decreased in Kazakhstan from 1990 until now. Farming, mining, and building are all indirectly changing the geography of some places. The use of rivers for cotton irrigation has shrunk by 3 quarters in the last 50 years and it is extremely affecting the Aral Sea. 

Edelin Espino's curator insight, December 13, 2014 3:10 PM

Is sad to see how humans are changing the environment forcing the wild creatures to abandon the places they've been living for hundred or years or die of starvation. I wonder what will happen in 300 years when there is no more big lakes and the oceans will be completed polluted .

Tanya Townsend's curator insight, November 20, 2015 2:57 PM

Great tool to show students how human use of natural resources can change landscapes and have permanent impacts on geographical landmarks such as the aerial sea. How do we stop it? Can we undo the damage done? How do we prevent these tragedies from happening in the future?

Aral Sea Basin

Aral Sea Basin | Walkerteach Geo | Scoop.it

"Dust blows from what was once the Aral Sea floor. Tragic mismanagement of a natural resource."


Via Seth Dixon
Luke Walker's insight:

This is exactly what we talked about in class this week. The Aral Sea is a perfect example of how man-made structures such as dams can impact hydrology and create physical water scarcity in certain regions of the world.

The after effects on human healthy are terrible.

Jess Deady's curator insight, April 30, 2014 8:36 PM

The Aral Sea Basin has been a topic of conversation throughout geography for many reasons. What used to be filled with water is now blowing dust because its that dry? This basin is no longer a natural resource.

Gene Gagne's curator insight, November 18, 2015 3:30 PM

Here is a question. Do you think perhaps in the future this could happen to lake Mead in Nevada/Arizona? With all the non-stop building and no rain perhaps one day could it run dry or do we have a way to stop it.

Gene Gagne's curator insight, December 1, 2015 7:17 PM

Once there is less water in a lake there is less water in the air therefore less rain. The long term consequences is that the fishing industry is destroyed where once upon a time there were 61000 workers and now there are under 2000. The water is more saltier. The lands are now ill suited and unbuildable. Also the people there are prone to health problems.
