This report presents complete texts or summaries of 21 presentations given at a seminar on the use of remote sensing technology in LDC's. Its purpose was to provide an overview of remote sensing uses to LDC administrators and decision-makers, while also treating in detail some key remote sensing techniques. The seminar was sponsored by AID's Office of Science and Technology and was organized and conducted by the Environmental Research Institute of Michigan. A total of 53 speakers, delegates, and observers (a list is provided), representing 17 nations and 4 international organizations, participated. The papers presented deal with the seminar's main themes. Papers 1-6 treat the causes and effects of desertification and the uses of remote sensing technology to solve desertification problems, including a discussion of technology transfer and resource monitoring. Papers 7-10 deal with agricultural production, including the use of area sampling frames to estimate agricultural production, multipurpose agriculture surveys, the use of satellite data in agricultural information systems, and agriculture monitoring and assessment. Paper 11, on the interrelationships between agriculture, forestry, and human land use, leads to papers 12-13 on the use of remote sensing in forestry and range inventory and monitoring. Papers 14-17 treat the uses of satellite data in exploring ground water sources, particularly in Egypt, Nigeria, and West Africa. Papers 18-19 review the relationship between remote sensing technology and Latin America's development needs. The final two papers discuss, respectively, the role of the United Nations in remote sensing and whether remote sensing can be considered an appropriate technology.
