Land Development program ("Khu dinh điền"): In early 1957, Diệm started a new program called the "Land Development" to relocate poor inhabitants, demobilized soldiers, and minority ethnic groups in central and southern Vietnam into abandoned or unused land in Mekong Delta and Central Highlands, and cultivating technological and scientific achievements to transform South Vietnam and ensure security and prevent communist infiltration. Diệm believed that the program would help improve civilians' lives, teach them the values of being self-reliant and hard working. At the end of 1963, the program had built more than two hundred settlements for a quarter of a million people. Nevertheless, the lacks of conditions in these areas along with the corruption and mercilessness of local officials failed the program.
