AbstractA community program that included keynote addresses rounded out the day's events on Sept. 1. University of Arizona's President Robert Shelton greeted about 225 people attending the community event. Ben Grumbles, director of the Arizona Department of Environmental Quality, further extended the welcome. The keynote speakers were Uri Shani, director general of the Israeli Water Authority, and Shaddad Attili, chairman of the Palestinian Water Authority. Attili, who was unable to attend the event in person, provided his message via DVD. Ayman Jarrar, director general for the regulatory and water control directorates of the Palestinian Water Authority, joined Shani at the podium to answer questions. Shani described Israel's predicament confronting the dire consequences of ongoing drought affecting the Middle East. “The trend is very clear, and we need to understand it. If we don't work on the future development of water, we don't solve anything. Demand is increasing, and the supply is decreasing, and we are left with no solution,” he said. With brackish water threatening groundwater reserves, Shani said the importance of desalination as a water source has increased. Conservation measures, a national priority, have decreased Israeli water consumption. Agricultural allocations are half what they were nine years ago. Contributing to the conservation savings is the relatively minimal water lost to evaporation and leakage, about 10 percent in Israel compared to much higher rates in other areas of the developed world. The use of reclaimed water has also increased dramatically. Attili discussed the precarious state of Palestinian water supplies. He said that water is a daily problem in the Palestinian Territories, with many communities lacking basic infrastructure for delivery of clean water and for water treatment. “We are trying to create a vibrant Palestinian state; our state will not be vibrant if there is not enough water.” He stressed the need for Israel to increase water allocations. Going beyond an acknowledgment of the political work to be done, Attili spoke of water supplies as a humanitarian cause. He said, “In the end of the day, it is a basic human need.” Jarrar sounded a pessimistic note with regard to an immediate solution to Palestinian water problems. He said what is needed is “political will from both sides, which is unfortunately not available at this time.” He said, “We are suffering, and the time should come to end our suffering with regard to the water supply.” He expressed confidence in Uri Shani's willingness to work with the Palestinian Water Authority, but also made clear that final decisions on critical water issues were often politicized and made at a higher level of government than the water authorities. The keynote session ended on a hopeful and conciliatory note. Despite the obstacles, Jarrar expressed optimism that trust can be built between the two sides, leading to adequate water supplies for both Israelis and Palestinians and contributing to peace in the region. Shaddad Attili also expressed confidence that he and the Palestinian Water Authority can work with Uri Shani and the Israeli Water Authority to resolve conflict in the area of water. Shani found significance in the fact that part of the conflict is about water. He said, "The general method to extinguish fire is to use water. I believe water can lead to peace, and this is my hope. Nobody promised us to have easy solutions, but it can be done.” The AzIP workshop was organized to help both Israelis and Palestinians achieve the goal of resolving conflict over water and working together to find shared solutions.

Yield and Water Use of Barley Cultivars Compared Under an Irrigation Water Gradient at Marana, 1987Ottman, Mike; Ramage, Tom; Brown, Paul; Thacker, Gary; Ottman, Mike (College of Agriculture, University of Arizona (Tucson, AZ), 1987-09)This study was initiated to determine how barley cultivars perform outside the environment for which they were selected. Also, a comparison was made of water use by a one-irrigation barley with water use of a commercial cultivar selected for high yield conditions. Six barley cultivars bred for differing growing conditions (Westbred Gustoe and Westbred Barcott - high input; Arivat and Prato - medium input; and, Seco and 2-22-9 - low input) were compared under 12 water regimes delivered by a line -source sprinkler system. Water use of Seco, a one-irrigation barley, and Westbred Gustoe, a commercial barley, was monitored with a neutron probe. The barley cultivars bred for high, medium, and low input conditions performed best in their respective optimum water levels with the exceptions of Westbred Barcott and Prato. Westbred Barcott (high input) yielded relatively well over all water levels, and Prato (medium input), performed similar to a high input barley. Seco (low input) used slightly less water than Westbred Gustoe (high input), primarily due to its earlier maturity. The water extraction pattern with depth was similar for both cultivars due to the frequent shallow irrigations applied in this study. The water extraction pattern of Seco needs to be investigated under one- irrigation conditions.
The Arizona Water Commission's Central Arizona Project Water Allocation Model SystemBriggs, Philip C.; Arizona Water Commission, Phoenix, Arizona (Arizona-Nevada Academy of Science, 1977-04-16)The purpose and operation of the Central Arizona Project water allocation model system are described, based on a system analysis approach developed over the past 30 years into an interdisciplinary science for the study and resolution of complex technical management problems. The system utilizes mathematical and other simulation models designed for computer operations to effectively solve such problems as the CAP faces including those concerned with social and economic considerations. The model is composed of two major components: (1) a linear program designed to determine the optimal allocation of all sources of water to all demands and, (2) a hydrologic simulator capable of reflecting the impact of distribution alternatives on per-unit cost of delivery. The model, currently being use, has substantially contributed to a greater understanding of water usage potential in Arizona.
