Farmers and fresh water : voluntary conservation to protect our land and waters
Farmers and fresh water : voluntary conservation to protect our land and waters : hearing before the Committee on Agriculture, Nutrition and Forestry, United States Senate, One Hundred Thirteenth Congress, second session, December 3, 2014.
In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.
Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.
The Man Who Thought He Owned Water is author Tershia d’Elgin’s fresh take on the gravest challenge of our time—how to support urbanization without killing ourselves in the process. The gritty story of her family’s experience with water rights on its Colorado farm provides essential background about American farms, food, and water administration in the West in the context of growing cities and climate change. Enchanting and informative, The Man Who Thought He Owned Water is an appeal for urban-rural cooperation over water and resiliency. When her father bought his farm—Big Bend Station—he also bought the ample water rights associated with the land and the South Platte River, confident that he had secured the necessary resources for a successful endeavor. Yet water immediately proved fickle, hard to defend, and sometimes dangerous. Eventually those rights were curtailed without compensation. Through her family’s story, d’Elgin dramatically frames the personal-scale implications of water competition, revealing how water deals, infrastructure, transport, and management create economic growth but also sever human connections to Earth’s most vital resource. She shows how water flows to cities at the expense of American-grown food, as rural land turns to desert, wildlife starves, the environment degrades, and climate change intensifies. Depicting deep love, obsession, and breathtaking landscape, The Man Who Thought He Owned Water is an impassioned call to rebalance our relationship with water. It will be of great interest to anyone seeking to understand the complex forces affecting water resources, food supply, food security, and biodiversity in America.
Balancing Water for Humans and Nature, authored by two of the world's leading experts on water management, examines water flows - the 'blood stream' of both nature and society - in terms of the crucial links, balances, conflicts and trade-offs between human and environmental needs. The authors argue that a sustainable future depends fundamentally on our ability to manage these trade-offs and encourage long-term resilience. They advocate an ecohydrological approach to land/water/environmental problems and advance a strong, reasoned argument for viewing precipitation as the gross fresh water resource, ultimately responsible for sustaining all terrestrial and aquatic ecosystem services. This book makes the most coherent and holistic argument to date for a new ecological approach to understanding and managing water resources for the benefit of all. Basing their analysis on per capita needs for an acceptable nutritional diet, the authors analyse predictions of the amounts of water needed for global food production by 2050 and identify potential sources. Drawing on small-scale experiences in Africa and Asia, they also cover the vulnerability of the semi-arid tropics through a simplified model of green and blue water scarcity components.
Explains how farming can be both environmentally and economically sound. An increase of efficiency in applying farm chemicals means a decrease in the risk of groundwater contamination and an increase in profits. Provides research and management tips on ways to cut back on pesticides and fertilizer without cutting yields, ways to determine which pesticides are less likely to leach, and ways to apply chemicals more efficiently. Also includes sections on chemical storage, wells, septic systems, livestock waste management, irrigation, chemigation, water testing, and water treatment. An ideal resource for farmers and anyone else concerned about water quality.
