Book Description
Energy requirements for irrigation vary widely across California as a function of the proximity of water sources, the methods of irrigation, and the water requirements of the crops. The objectives of this study are to determine water and energy use for agricultural irrigation and during the 1977 season; describe the responses of agriculture to the drought conditions of 1977; and identify the present and potential water and energy conservation sstrategies applicable to California. The analysis of electricity and water requirements for irrigated agriculture was started as a part of a two-phase project. The purposes of the overall study are to assess the impacts of the drought on California electricity supply and demand, to evaluate remedial measures, and to develop a methodology for such assessments. The methodology used for determining electricity requirements to pump irrigation water focuses on the hydrologic basins of the Central Valley. The method employs several factors to calculate the final energy demand for pumping. The factors include unit energy use to obtain ground and surface water, average water use by individual crop, type of irrigation, and estimated crop acreage planted in 1977. Section II (''Energy/Water Use During Drought Year'') contains the assumptions and calculations used to determine the total electricity demand. The dry years of 1976 and 1977 present an opportunity to gain a better understanding of how farmers meet their irrigation needs with limited supplies of surface water. Section III (''Agriculture's Responses of Drought Conditions'') outlines the major strategies employed in 1977. Since the overall purpose of this present study is to determine if this information can help develop a long-term approach for water and energy conservation in irrigated agriculture, the present and potential conservation trategies applicable to California were identified and presented in Section IV.
Quantifying Water and Energy Linkages in Irrigation

Book Description
While Asia has the world's fastest-growing economy, 29 of 48 countries assessed by the Asian Water Development Outlook are water-insecure, posing a threat to the region's continued growth. As economies develop, increasing demands will be placed on water for food and water for energy. In the irrigation subsector, energy is required for ground and surface water pumping, as well as for fueling on-farm irrigation technology and other farm machinery. Water and energy are intrinsically linked, yet there is limited information on quantifying energy use in irrigation systems. This publication summarizes the results of a pilot study to quantify water and energy use in high-efficiency irrigation systems within drought-affected provinces in Viet Nam.
Water Conservation, Reuse, and Recycling

Book Description
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.

Science Breakthroughs to Advance Food and Agricultural Research by 2030

Pages : 243
Book Description
For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).
