Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | CLIL-DNL Geography | 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.

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.

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 .

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?
