Drying of the Aral Sea

Kaitlin Young's curator insight, October 7, 2014 11:27 AM

The Aral Sea’s receding waters could prove fatal to the surrounding agriculture. Both Uzbekistan and Kazakhstan diverted the rivers that flowed into the Sea in the 1960s to feed their growing cotton and rice farms. Over the last five decades, the lack of a water source flowing into the Aral Sea combined with harsher droughts due to climate change have caused the water to evaporate at an alarming rate. As the water evaporates, large deposits of minerals remain on the bare lake bed. Winds pick up the mineral deposits and often spread them onto farms, where the increased salinity destroys rice paddies and other crops. The destruction of crops causes less food production, so less money is made by the farmers and more money has to be spent to bring in food to avoid famine. Cotton crops are also destroyed, so the region loses yet another source of income.

The increased evaporation of the Aral Sea has also caused an incredible increase to salinity levels in the lake itself. The extremely salty water cannot be used without heavy removing the salt, which is incredibly unaffordable in an already stressed region. Small subsidence farmers and local farmers cannot use the resource at hand. The fishing industry has completely collapsed, thus removing another important resource from the area.

If a wounded economy and unreliable food was not enough, the air born minerals blown away from the lake are causing numerous health problems. Respiratory issues, such as asthma, are becoming more and more common in the communities surrounding the Aral Sea due to the minerals and industrial debris in the air. The disappearance of the Sea has created the perfect conditions for the collapse of a region. The struggle that the people have to endure often escalates into increased social and political unrest, and disputes often occur. The Aral Sea exemplifies how one small environmental change can set off a chain of devastating events that lead to irreversible effects.

The drying of the Aral Sea opens our eyes to how fragile our environment is and the scarcity of resources.  We need to become more aware of our resources, because as they saying goes, the "well will run dry."

Shanelle Zaino's curator insight, October 22, 2014 2:33 PM

This video shows a time lapse of the Aral Sea's near demise. A once viable fishing area this salt lake now resembles a desert. The Aral Sea is comprised of salt water however much of the water being funneled in was fresh. Through human tampering this body of water has nearly dried. Some areas have been "saved" through damming and heavy rain fall although it may be too late for the southern end of the Aral Sea.

aprender matemáticas tiene mucho que ver con ver la parte lúdica de las mismas.  estas páginas son muy adecuadas addemás para sistematizar diversas operaciones de manera atractiva, siendo más eficaces que las fichas repetitivas.

I Need Some Space

An armchair ride through our solar system, to the classical music overtures of the Zephyr Quartet.
I put this compliation together using After effects, Element 3d, some NASA models, Trapcode suite and a lot of time waiting for renders. The beautiful music is from the Zephyr Quartet's album 'Esque' with my sister Belinda Gehlert on violin, Emily Tulloch - violin, Jason Thomas – Viola and Hilary Kleinig playing Cello.
