Why do you think the shorelines of the Aral Sea have receded 60-80 km? The Aral Sea Crisis This has happened because in the early 1960s, the two rivers that channelled water to the Aral Sea were diverted to irrigate areas of the surrounding desert to grow rice, melons, cereals and cotton.
Focus Questions The Aral Sea Crisis What two main rivers channel into the Aral Sea? What two countries does the Aral Sea border? Why was the water from the main two rivers diverted? What government was responsible for diverting the flow of the two main rivers?
Focus Questions The Aral Sea Crisis 5. What percentage of its original size is the Aral Sea now? 6. Is it likely that the Aral Sea will ever return to its original size? 7. What are some of the consequences of this crisis? (List at least four.) 8. What are some possible environmental solutions?
