Mao's Great Leap Forward
"Private plot farming was abolished and rural farmers were forced to work on collective farms where all production, resource allocation, and food distribution was centrally controlled by the Communist Party. Large-scale irrigation projects, with little input from trained engineers, were initiated, and experimental, unproven new agricultural techniques were quickly introduced around the country. These innovations resulted in declining crop yields from failed experiments and improperly constructed water projects. A nationwide campaign to exterminate sparrows, which Mao believed (incorrectly) were a major pest on grain crops, resulted in massive locust swarms in the absence of natural predation by the sparrows. Grain production fell sharply, and hundreds of thousands died from forced labor and exposure to the elements on irrigation construction projects and communal farming. Famine quickly set in across the countryside, resulting in millions more deaths. People resorted to eating tree bark and dirt, and in some areas to cannibalism. Farmers who failed to meet grain quotas, tried to get more food, or attempted to escape were tortured and killed along with their family members via beating, public mutilation, being buried alive, scalding with boiling water, and other methods."
