In their role as change agents, rural development personnel often modify the environment in which they are operating when they introduce different technology, institutional modifications, etc. Because these actions can change the relationship between the rural population and its habitat and may encourage out-migration or in-migration, rural development personnel should become more sensitive to the relationship between rural development and migration. Intended for personnel working in the area of agriculture aid, this guide explores that relationship and points out needs for further research. Part I is designed to teach basic concepts, focusing on (1) conditions/measures which tend to act as disincentives to migration; (2) rural development activities which tend to act as incentives to migration; and (3) rural development activities which tend to encourage migrants to rural areas to remain in their new destinations. Part II considers specific aspects of migration. Section I of Part II covers the urban bias, including its development, its effect on migration and rural development; the urban-rural dichotomy; and the urban-rural-continuum. The second section discusses the significance of distance; its relevance to rural development agents; and several research approaches to distance, including physical, sociological, itemized, and global-comprehensive approaches. Section III considers human rights in relation to migration, and the final section outlines a theoretical approach to the role of development on some aspects of migration. (DS)
