Book Description
Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

Book Description
Prehistoric farmers in Mexico invented irrigation, developed it into a science, and used it widely. Indeed, many of the canal systems still in use in Mexico today were originally begun well before the discovery of the New World. In this comprehensive study, William E. Doolittle synthesizes and extensively analyzes all that is currently known about the development and use of irrigation technology in prehistoric Mexico from about 1200 B.C. until the Spanish conquest in the sixteenth century A.D. Unlike authors of previous studies who have focused on the political, economic, and social implications of irrigation, Doolittle considers it in a developmental context. He examines virtually all the known systems, from small canals that diverted runoff from ephemeral mountain streams to elaborate networks that involved numerous large canals to irrigate broad valley floors with water from perennial rivers. Throughout the discussion, he gives special emphasis to the technological elaborations that distinguish each system from its predecessors. He also traces the spread of canal technology into and through different ecological settings. This research substantially clarifies the relationship between irrigation technology in Mexico and the American Southwest and argues persuasively that much of the technology that has been attributed to the Spaniards was actually developed in Mexico by indigenous people. These findings will be important not only for archaeologists working in this area but also for geographers, historians, and engineers interested in agriculture, technology, and arid lands.
