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...

This new volume in the Innovations and Challenges in Micro Irrigation series covers an array of technologies to estimate evapotranspiration and to evaluate parameters that are needed in the management of micro irrigation, with worldwide applicability to irrigation management in agriculture. Topics include recent evapotranspiration research, performance evaluation of filters and emitters, evaluation of fertigation and ground water with treated wastewater effluent, performance of pulse drip irrigated potato under organic agriculture practices in sandy soils, impact of polyethylene...

The scarcity of surface water which has so marked the Great Plains is even more characteristic of its subdivision, the Texas High Plains. Settlers on the plateau were forced to use pump technology to tap the vast ground water resources--the underground rain--beneath its flat surface.

The evolution from windmills to the modern high-speed irrigation pumps took place over several decades. Three phases characterized the movement toward irrigation. In the period from 1910 to 1920, large-volume pumping plants first appeared in the region, but, due to national and regional circumstances,...

This book addresses strategies for food security and sustainable agriculture in developing economies. The book focuses primarily on India, a fast developing economy, whose natural resource base comprising land and water supporting agricultural production is not only under enormous stress, but also complex and not amenable to a uniform strategy. It critically reviews issues which continue to dominate the debate on water management for agricultural and food production.

The book examines the validity of the claim that large water resources projects cause serious social and...
