Riparian ecosystems are declining throughout the southwestern United States, where many have disappeared completely; yet progress toward checking their decline has been marginal, and the results of only a few recovery projects have been evaluated. In this guidebook, Mark K. Briggs has filled this gap in riparian conservation literature. Based on his experiences gleaned from evaluating the results of many riparian rehabilitation projects, Briggs presents these results in a manner that biologists, hydrologists, government planners, resource managers, and other concerned citizens can immediately apply toward developing site-specific recovery strategies. The book opens with a review of watershed characteristics and an examination of drainage systems, then proceeds to determining the causes of riparian decline. It introduces five factors that have a significant effect on the results of riparian rehabilitation--natural regeneration, water availability, channel stability, direct impacts such as livestock grazing and recreational activities, and soil salinity--and offers case studies that demonstrate how revegetation has been used both effectively and ineffectively. It also discusses strategies other than revegetation that may be effective in improving the ecological condition of a site. Many of the strategies presented are also relevant to nonarid climates and to urban areas. By emphasizing evaluation of riparian ecosystems, so that the causes of degradation can be understood, and by offering general approaches that can be tailored to specific situations, Riparian Ecosystem Recovery in Arid Lands takes a holistic approach to riparian recovery that will enable users to better judge whether recovery expenditures are likely to produce desired results. An unprecedented work, it will substantially add to efforts across the Southwest and elsewhere to restore these unique and priceless ecosystems.

Canals and Communities: Small-Scale Irrigation Systems (Arizona Studies in Human Ecology)

From the mountains of South America to the deserts of northern Africa to the islands of south Asia, people have devised myriad ways of moving water to sustain their communities and nourish their crops. Many of these irrigation methods have been used over long periods of time and continue to function in diverse ecological and sociopolitical contexts. This book presents case studies and comparative essays about local institutions for managing water resources. Drawn from around the globe, the cases clearly demonstrate that "indigenous" irrigation is often more sustainable, cost-effective, and flexible than has been generally believed. The contributors discuss a wide range of environments, cultural traditions, and historical contexts in which such systems operate, maintaining a common focus on incentives for cooperation, operational rules, collective-choice arrangements, principles of allocation, and conflict-resolution mechanisms. Canals and Communities can serve as a sourcebook for social scientists and development planners investigating the cultural ecology of irrigated agriculture, the ethnology of cooperative social formations, the politics of collective-resource institutions, and the sociology of rural development. The book also provides examples and generalizations about the cross-cultural characteristics of sustainable water resource management and intensive agriculture. Aside from its theoretical contributions to human ecology and anthropology, the book is of practical importance to development studies. The cases it presents make a convincing argument for perpetuating small-scale irrigation systems as part of the world's repertoire of irrigation knowledge and resources.
