The 2009 Navajo Nation Long Range Transportation Plan is a twenty-year comprehensive plan developed and updated by the Navajo Division of Transportation in a five-year cycle. The plan identifies the Nation’s multi-modal transportation needs over the next 20 years and develops strategies to meet them. The plan provides long range planning policies and implementation strategies for the Navajo Indian Reservation Roads Program improvements. It is based on a comprehensive analysis of all pertinent factors and issues affecting the Navajo Nation’s existing and future transportation needs.

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.

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.

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.

This version of the Major Streets and Routes Plan revises the original plan and the 2004 revisions. Looking ahead to pending updates to the classification systems of towns and cities in Maricopa County, the original MSRP stipulated a periodic review and modification of the street functional classification portion of the plan. This revision incorporates the following changes: (1) as anticipated, many of the communities in the County have updated either their general or transportation plans in the time since the adoption of the first MSRP; (2) a new roadway classification, the Arizona Parkway, has been added to the Maricopa County street classification system and the expressway classification has been removed; and (3) a series of regional framework studies have been conducted by the Maricopa Association of Governments to establish comprehensive roadway networks in parts of the West Valley.
