A network of irrigation canals was built in the steppe belt of the southern Soviet Union, and in the deserts of Central Asia. A project was proposed to plant trees in a gigantic network of shelterbelts or windbreaks across the steppes of the southern Soviet Union, similar to what had been done in the northern plains of the United States in the 1930s following drought and the extensive damage of the Dust Bowl years. The idea was that planting windbreaks around rivers of southern Russia and around collective farms would supposedly stop the drying winds from Central Asia that were thought to have caused the drought. The actions were surrounded by a great deal of propaganda which included a patriotic oratoria, the Song of the Forests, composed by Dmitri Shostakovich. The plan was to be overseen by the Glavnoe upravlenie pelzashchitnogo lesorazvedeniaa which came under a scientific technical committee that included Trofim Lysenko. Lysenko claimed that he was an expert on planting trees in "nests" - where members of the same species helped each other. He planted at high densities and claimed that plants underwent "self-thinning" working together against weeds in the early stages and then some plants would sacrifice themselves for the main plant. He further suggested that a oak seedling at the center would have four seeds around them in a plus pattern. One ecologist and opponent of Lysenko, Vladimir N. Sukachev recorded that by September 1951, 100% of the trees planted using the "nest method" in the Ural territories had died. Although the plan achieved none of its stated goals, some collective farms surrounded by plantations produced better yields due to improved water storage. The Soviet government launched a number of extensive projects in land improvement, hydroengineering for water control, irrigation and power, and in supporting areas. Planned for completion in 1965, the projects were mostly abandoned after the death of Stalin in 1953. Under Stalin's plan water from the Syrdarya was diverted for agriculture to Kizil-Orda in Kazakhstan and near Tashkent. Agricultural intensification continued with canal construction under Stalin's successors Nikita Khrushchev and Leonid Brezhnev. By the 1970's no water from the Syrdarya reached the Aral Sea while the Amudarya added only a trickle. The two rivers irrigated about 17 million acres which grew mainly rice and cotton. This led to the drying of the Aral Sea, shrinking to about a 10th of its original extent, and increased salinity.
