Introductionagrarian reform, redistribution of the agricultural resources of a country. Traditionally, agrarian, or land, reform is confined to the redistribution of land; in a broader sense it includes related changes in agricultural institutions, including credit, taxation, rents, and cooperatives. Although agrarian reform can result in lower agricultural productivity, especially if it includes collectivization, it may increase productivity when land is redistributed to the tiller. Pressure for modern land reform is most powerful in the underdeveloped nations. See also collective farm.
