Long Distance Exchange in Pre-Hispanic Chaco Canyon and the Mimbres Valley, New Mexico: A Comparison
Given that a major share of a society's culturally significant cognitive features is expressed most productively by means of language, in this study I rely on aspects of language to ascertain Wixárika landscape conceptualization and materialization. Through the linguistic analysis of placenames and place-talk, I determine the meanings with which the Wixárika landscape is imbued. Through the analysis of the utterance of placenames, I provide examples of how the landscape is instilled with meaning. Utilizing native terminology, I characterize the content of the Wixárika landscape, and describe the process, in terms of movements, whereby the landscape is actualized.
Results indicate that the Wixárika conceptualize their landscape in diverse ways, including as a dwelling, a repository of memories, and a source of identity. The process and manifestation of Wixárika landscape conceptualization yield insights pertinent to understanding ancient landscapes, especially with regard to content and scope. This study is significant in that it represents the landscape from an indigenous perspective. It also sheds light on the construction of a living landscape, and thus is a useful framework for contemplating the past.
In this three-paper dissertation, I evaluate the adaptive capacity of the water management systems of two medieval Khmer cities, located in present-day Cambodia, over the course of centuries. Angkor was the capital of the Khmer Empire for over 600 years (9 th -15 th centuries CE), except for one brief period when the capital was relocated to Koh Ker (921 – 944 CE). These cities both have massive water management systems that provide a comparative context for studying resilience; while Angkor thrived for hundreds of years, Koh Ker was occupied as the capital of the empire for a relatively short period. In the first paper, I trace the chronological and spatial development of two types of settlement patterns (epicenters and lower-density temple-reservoir settlement units) at Angkor in relation to state-sponsored hydraulic infrastructure. In the second and third papers, I conduct a diachronic analysis using empirical data for the adaptive capacity of the water management systems at both cities. The results suggest that adaptive capacity is useful for identifying causal factors in the resilience and failures of systems over the long term. The case studies also demonstrate the importance and warn of the danger of large centralized water management features.
This study investigates the impact of urban form and landscaping type on the mid-afternoon microclimate in semi-arid Phoenix, Arizona. The goal is to find effective urban form and design strategies to ameliorate temperatures during the summer months. We simulated near-ground air temperatures for typical residential neighborhoods in Phoenix using the three-dimensional microclimate model ENVI-met. The model was validated using weather observations from the North Desert Village (NDV) landscape experiment, located on the Arizona State University's Polytechnic campus. The NDV is an ideal site to determine the model's input parameters, since it is a controlled environment recreating three prevailing residential landscape types in the Phoenix metropolitan area (mesic, oasis, and xeric). After validation, we designed five neighborhoods with different urban forms that represent a realistic cross-section of typical residential neighborhoods in Phoenix. The scenarios follow the Local Climate Zone (LCZ) classification scheme after Stewart and Oke. We then combined the neighborhoods with three landscape designs and, using ENVI-met, simulated microclimate conditions for these neighborhoods for a typical summer day. Results were analyzed in terms of mid-afternoon air temperature distribution and variation, ventilation, surface temperatures, and shading. Findings show that advection is important for the distribution of within-design temperatures and that spatial differences in cooling are strongly related to solar radiation and local shading patterns. In mid-afternoon, dense urban forms can create local cool islands. Our approach suggests that the LCZ concept is useful for planning and design purposes.
