The book discuses the history of water management around the Aral Sea basin. From the 19th century on to mid 20th. Particularly focuses on the indigenous methods vs the Imperial Russian and later Soviet interventions in the environment to build civilization, stability, and agriculture, particularly cotton farming into the 20th century.
The author explores why water management was critical as a colonial project. Russians/Soviets sought to force nomads into more controllable sedentary lifestyles and make Central Asia a profitable colonial project through the exploitation of cotton. An industry that continues to dominate the central Asian economy despite the impact it has on the environment.
The book is rather dry and gets into the details of arguments made by politicians and engineers on projects that failed and succeeded, and why. Extraordinarily comprehensive work on the subject. Although the draining of the Aral Sea itself was a bit sudden in the book given the scale of the ecological disaster, it was by then part and parcel for the Soviet projects that saw the environment as something to exploited first and foremost.
