Water-Related Technologies for Sustainable Agriculture in Arid/Semiarid Lands. Selected Foreign Experience

摘要

This report complements the forthcoming Office of Technology Assessment on water and agriculture in U.S. arid/semiarid lands. The full assessment focuses on U.S. experience. The global significance of agricultural research and development on arid/semiarid lands is underscored by the fact that as much as 20 percent of the Earth's surface is arid and semiarid, containing nearly 16 percent of the world's population. Described in the report are selected foreign experiences using technology to develop and sustain agriculture in arid lands.
