The opening section deals first with the benefits of arid land irrigation and the effective use of water in irrigated agriculture. This section also tackles the public health and socio-economic impacts of irrigation, as well as the planning and managing of irrigation and drainage systems. The Arid Lands was originally published as Report on the Lands of the Arid Regions of the United States in Wallace Stegner (–93) is the author of The Gathering of Zion and Mormon Country, both available in Bison Books editions. John Vernon is Distinguished Professor of English at Binghamton University and the author of ten by: 7. In the arid land along the Colorado River, use of the river's water is strictly controlled: farms along the river each have a limited allocation that they are allowed to use for irrigation. But the trees that grow in narrow strips along the river's banks also use its water. The Colorado River (Spanish: Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern 1,mile-long (2, km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across.
Consequently, Colorado farmers, politicians, and businesses developed sophisticated irrigation systems and complex laws for capturing, storing, and moving water from source to field. Beginnings. Though irrigation in the West has been practiced for over a millennium, its continuous use in Colorado stems from the mids. irrigation and salt-threatened arid land reclamation and management provided the guiding principles for develop-ment of irrigation throughout the western U.S. from (with passage of the Reclamation Act) to the close of the 20th century (3). The science of irrigated agriculture and arid zone soil science in general relied heavily on the. The International Commission on Irrigation and Drainage is dedicated to enhancing the worldwide supply of food and fibre for all people by improving water and land management and the productivity of irrigated and drained lands through appropriate management of water, environment and application of irrigation, drainage and flood management techniques. From its source high in the Rocky Mountains, the Colorado River channels water south nearly 1, miles, over falls, through deserts and canyons, to the lush wetlands of a vast delta in Mexico and.
Hispano settlers began building widespread irrigation systems to cultivate the once unusable arid lands (Hicks et al. ). Water resources were shared equitably among the community via a canal system, and anyone that wanted water had an opportunity to use this common-pool resource. tion of Colorado River water, a large portion of the remainder of the area became affected by high water tables. This can be attributed to the shutting down of wells and allowing the ground water to rise by the abundant use of irrigation Ovate.;, Along with this, a salinity problem developed. A means had to be provided to drain the land. Current land-use modifications influence ground-water recharge through vegetation, irrigation, and impermeable area. High mountain ranges bounding the study area—the San Bernadino Mountains and Sierra Nevada to the west, and the Wasatch and southern Colorado Rocky Mountains to the east—provide external geologic controls on ground-water. Other extensive areas reclaimed from a desert or near-desert status by irrigation are found in Israel, Egypt and other countries of the Middle East, India, Mexico, Peru, Russia, and tion of arid lands has been practised in the Middle East for thousands of years and extensive irrigation projects were developed in what is now southwestern United States by American Indians long before.
