A 7500 mile journey across Asia along the old Silk Road

Another shot of the Qaraqum Canal. Construction was started by the Soviets in 1954 and completed in 1988. The intention was to open up huge tracts of former desert land to agriculture, mainly cotton monoculture. However, the primitive construction of the canal means allows almost 50% of the water to escape en route. The canal is also a major factor leading to the Aral Sea environmental disaster.
