If shows how such techniques allow a detailed mapping of land use changes and includes details of the location of the agricultural land lasses, the nature of the land use changes that caused these and the qualify of the agricultural land that was lost. The paper also describes which non agricultural land uses were responsible for most of the agricultural land losses and discusses what these findings imply for India and for other nations where urbanization is reducing the supply of high quality agricultural land.
