As a major component of the Climate Assessment Project for the Southwest, this study is part of a larger effort to assess the vulnerability of natural and human systems to climate variability and change in the southwestern U.S. As importantly, this assessment seeks to fulfill the project’s larger mission of working directly with communities to improve their ability to respond adequately and appropriately to climatic events and climate change. The goal of this study is to demonstrate the utility of a rapid ethnographic approach for (1) conducting a community-level assessment of climate related vulnerability and (2) extending the findings to other assessments.

Conventional wisdom often views the urban water sector as being among the more sensitive sectors in the arid U.S. Southwest. To test this assumption, the Climate Assessment Project for the Southwest analyzed the water budgets of five Arizona cities to determine how severe the impacts would be from the deepest one-, five-, and ten-year droughts on record. Case study sites for the analysis included the Phoenix Active Management Area, Tucson Active Management Area, Santa Cruz Active Management Area, and the Benson and Sierra Vista subwatersheds of the San Pedro River.

Most of the state's cattle ranches rely solely on rain-fed range to support their herds. Drought conditions can result in significant declines in forage production and nutritional quality. Failure to respond to these changes with appropriate management can compound the effects of drought on already stressed vegetation resulting in poor range condition and animal performance. The project discussed in this paper has three broad purposes: first, to compile a profile of Arizona's ranchers, with an emphasis on socioeconomic characteristics of ranchers in the southeastern portion of the state; second, to identify and understand the physical, social, and political-economic factors that make the livelihoods of ranchers vulnerable to climatic variability; and third, to determine whether or not ranchers can mitigate their vulnerability with improved access to information on climate. The project is in its initial stages and thus no conclusive data are available at this time. In this paper we will outline our assumptions in entering the project, our methodology, and some preliminary assessments from our work to date.

This summary report overviews a State of Arizona and U. S. Department of Energy funded drilling project to determine if near-term hot dry rock (HDR) geothermal potential exists in the eastern portion of the White Mountains region of Arizona. A 4,505 feet deep slim-hole exploratory well, Alpine1/Federal, was drilled within the Apache-Sitgreaves National Forest at Alpine Divide near the Alpine Divide camp ground about 5 miles north of Alpine, Arizona in Apache County (Figure 1). A comprehensive technical report, in two parts, details the results of the project. Part 1, Alpine1/Federal, Drilling Report, discusses the drilling operations,
logging program, permitting and site selection for the hole. Part 2, Temperature Gradients, Geothermal Potential, and Geology, summarizes the temperature gradients, heat flow, geothermal potential, and subsurface geology.
