Proceedings of a conf. on the major problems facing grasslands in arid & semi-arid regions of the U.S. & Mexico & to seek solutions to those problems. Grasslands in many parts of the Southwest & northern Mexico are facing serious threats -- from urbanization & subdivision development to spread of invasive plant species to conflicts over grazing policy. Target groups for participation included private landowners, non-profit groups, government agencies, environmental advocates, economists, scientists, etc. Emphasized practical, hands-on mgmt. methods, including time in grasslands managed under a variety of techniques.

The original "The Future of Arid Lands", was edited by Gilbert White and was published in 1956, comprised papers delivered at the "International Arid Lands Meetings" held in New Mexico in 1955. At these meetings, sponsored by UNESCO and the American Association for the Advancement of Science, experts considered the major issues then confronting the world's arid lands and developed a research agenda to address these issues. "The Future of Arid Lands - Revisited", was commissioned by UNESCO in 2005, and re-examines this earlier work. Written by researchers from the University of Arizona, this volume first looks at the state of science in 1956 and attendant contemporary views of arid lands development. It then considers how scientific understanding of the processes governing arid lands has since evolved, before extracting lessons from these comparisons that might guide current and future arid land managers and speculating on what the future might hold for arid lands.

This publication reviews both published and unpublished sources on Puebloan, Hispanic, and AngloAmerican irrigation systems in the Rio Grande Valley. Settlement patterns and Spanish and Mexican land grants in the valley are also discussed. The volume includes an annotated bibliography.
