The study had three main goals: (1) to assess the vulnerability of groundwater-dependent agriculture to climate variability, (2) to identify historical and current processes of adaptation to the vagaries of climate in the region— these refer to both system wide adaptations and individual farmer’s adaptations, and, (3) to assess the use of and needs for seasonal climate forecast information in agricultural decision making. The report is targeted at institutional stakeholders (i.e., agricultural extension personnel), physical scientists (particularly climatologists), and policymakers (at the level of NOAA and other federal agencies). Specific recommendations are made to these groups in order to improve the delivery of seasonal forecasts, set research priorities, and inform public policy.

Tribes have a direct government-to-government relationship with the U.S. government wherein no decisions about their lands and people are made without their consent. In Arizona, for example, American Indian reservations occupy nearly 30 percent of the land. Native Americans have a legal and moral claim to significant quantities of water as well. Because of their special legal standing in the United States, tribes are not just another group of stakeholders to be considered in the research and policy process. The purpose of this paper is to provide a legal and political background for interactions between the United States and tribal governments and provide models for those interactions, with special attention to research and outreach.
