Leading landscape architect and planner Carl Steinitz has developed an innovative GIS-based simulation modeling strategy that considers the demographic, economic, physical, and environmental processes of an area and projects the consequences to that area of various land-use planning and management decisions. The results of such projections, and the approach itself, are known as "alternative futures."

Alternative Futures for Changing Landscapes presents for the first time in book form a detailed case study of one alternative futures project—an analysis of development and conservation options for the Upper San Pedro River Basin in Arizona and Sonora, Mexico. The area is internationally recognized for its high levels of biodiversity, and like many regions, it is facing increased pressures from nearby population centers, agriculture, and mining interests. Local officials and others planning for the future of the region are seeking to balance the needs of the natural environment with those of local human communities.

The book describes how the research team, working with local stakeholders, developed a set of scenarios which encompassed public opinion on the major issues facing the area. They then simulated an array of possible patterns of land uses and assessed the resultant impacts on biodiversity and related environmental factors including vegetation, hydrology, and visual preference. The book gives a comprehensive overview of how the study was conducted, along with descriptions and analysis of the alternative futures that resulted. It includes more than 30 charts and graphs and more than 150 color figures.

Scenario-based studies of alternative futures offer communities a powerful tool for making better-informed decisions today, which can help lead to an improved future. Alternative Futures for Changing Landscapes presents an important look at this promising approach and how it works for planners, landscape architects, local officials, and anyone involved with making land use decisions on local and regional scales.

Arizona’s San Pedro Valley is a natural corridor through which generations of native peoples have traveled for more than 12,000 years, and today many tribes consider it to be part of their ancestral homeland. This book explores the multiple cultural meanings, historical interpretations, and cosmological values of this extraordinary region by combining archaeological and historical sources with the ethnographic perspectives of four contemporary tribes: Tohono O’odham, Hopi, Zuni, and San Carlos Apache.

Previous research in the San Pedro Valley has focused on scientific archaeology and documentary history, with a conspicuous absence of indigenous voices, yet Native Americans maintain oral traditions that provide an anthropological context for interpreting the history and archaeology of the valley. The San Pedro Ethnohistory Project was designed to redress this situation by visiting archaeological sites, studying museum collections, and interviewing tribal members to collect traditional histories. The information it gathered is arrayed in this book along with archaeological and documentary data to interpret the histories of Native American occupation of the San Pedro Valley.

This work provides an example of the kind of interdisciplinary and politically conscious work made possible when Native Americans and archaeologists collaborate to study the past. As a methodological case study, it clearly articulates how scholars can work with Native American stakeholders to move beyond confrontations over who “owns” the past, yielding a more nuanced, multilayered, and relevant archaeology.
