During the Vietnam War, between 1962 and 1971, the United States military sprayed 20,000,000 US gallons (80,000,000 L) of chemical herbicides and defoliants in Vietnam, eastern Laos and parts of Cambodia, as part of Operation Ranch Hand. The program's goal was to defoliate forested and rural land, depriving guerrillas of cover; another goal was to induce forced draft urbanization, destroying the ability of peasants to support themselves in the countryside, and forcing them to flee to the U.S. dominated cities, thus depriving the guerrillas of their rural support base and food supply.<br/><br/> The US began to target food crops in October 1962; in 1965, 42 percent of all herbicide spraying was dedicated to food crops. Rural-to-urban migration rates dramatically increased in South Vietnam, as peasants escaped the destruction and famine in the countryside by fleeing to the U.S.-dominated cities. According to Vietnamese Ministry of Foreign Affairs, 4.8 million Vietnamese people were exposed to herbicides, resulting in 400,000 people being killed or maimed, and 500,000 children born with birth defects.
Operation Ranch Hand was a U.S. Military operation during the Vietnam War; lasting from 1962 until 1971. It was part of the overall herbicidal warfare program during the war called 'Operation Trail Dust'. Ranch Hand involved spraying an estimated 20 million US gallons of defoliants and herbicides over rural areas of South Vietnam in an attempt to deprive the NLF (Viet Cong) of vegetation cover and food. Areas of Laos and Cambodia were also sprayed to a lesser extent. Nearly 20,000 sorties were flown between 1961 and 1971.
