In the Western Cape fruit growing area, a traditional long-standing practice of paying farm workers with rations of alcohol is known as the DOP system. Beyond limiting the wages earned by the workers, this practice promotes a dependence on alcohol persisting and permeating through generations within the local communities. A cycle of poverty is maintained leading to detrimental consequences such as domestic violence and foetal alcohol syndrome as explained in a case study called Dop till you Drop.
