Development-induced displacement and resettlement (DIDR) occurs when people are forced to leave their homes in a development-driven form of forced migration. Historically, it has been associated with the construction of dams for hydroelectric power and irrigation, but it can also result from various development projects such as mining, agriculture, the creation of military installations, airports, industrial plants, weapon testing grounds, railways, road developments, urbanization, conservation projects, and forestry.
Development-induced displacement is a social problem affecting multiple levels of human organization, from tribal and village communities to well-developed urban areas. Development is widely viewed as an inevitable step towards modernization and economic growth in developing countries; however, for those who are displaced, the result is most often loss of livelihood and impoverishment.
