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.

Looking at the images above it is understandable that the disappearance of the Aral Sea is known as the greatest environmental disaster (that we are not talking about). The amount of change that has taken place in this area is incomprehensible for the amount of time it has taken. Humans so often do not consider their actions on this planet , I believe what has taken place here is an utter shame.

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 .
