The project intersects the environmental humanities, critical theory, and cultural studies with the Desert Southwest. It explores the fullness of desert places with regard to cultures, borders, and languages, as well as nonhuman forces and intensities like heat, light, and distance. Dispelling the dominant notion of desert as void or wasteland, it sets a stage to suit the polyvocality of desert place. My work is interdisciplinary because the desert demands it. It begins with Cormac McCarthy’s Blood Meridian in order to reorient readers towards the rupture of the US War With Mexico which helped set the national and cultural borders in effect today. I then explore Denis Villeneuve’s film Sicario to emphasize the correlation between political hierarchy and verticality; those who can experience the desert from above are exempt from the conditions below, where Urrea’s The Devil’s Highway and Gaspar de Alba’s Desert Blood take place. The novels expose the immanence and violence of being on the ground in the desert and at the lower end of said hierarchies. Analyzing Yuri Herrera’s Signs Preceding the End of the World and Mora’s Encantado enables what I term a desert hauntology to produce a desert full of memory, myth, ancestors, and enchantment. Finally, the project puts visual artists James Turrell and Rafa Esparza in conversation to discover a desert phenomenology. The result is an instigation of how far is too far when decentering the human, and what role does place-based art play in creating and empowering community.

Summer daytime cooling efficiency of various land cover is investigated for the urban core of Phoenix, Arizona, using the Local-Scale Urban Meteorological Parameterization Scheme (LUMPS). We examined the urban energy balance for 2 summer days in 2005 to analyze the daytime cooling-water use tradeoff and the timing of sensible heat reversal at night. The plausibility of the LUMPS model results was tested using remotely sensed surface temperatures from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery and reference evapotranspiration values from a meteorological station. Cooling efficiency was derived from sensible and latent heat flux differences. The time when the sensible heat flux turns negative (sensible heat flux transition) was calculated from LUMPS simulated hourly fluxes. Results indicate that the time when the sensible heat flux changes direction at night is strongly influenced by the heat storage capacity of different land cover types and by the amount of vegetation. Higher heat storage delayed the transition up to 3 h in the study area, while vegetation expedited the sensible heat reversal by 2 h. Cooling efficiency index results suggest that overall, the Phoenix urban core is slightly more efficient at cooling than the desert, but efficiencies do not increase much with wet fractions higher than 20%. Industrial sites with high impervious surface cover and low wet fraction have negative cooling efficiencies. Findings indicate that drier neighborhoods with heterogeneous land uses are the most efficient landscapes in balancing cooling and water use in Phoenix. However, further factors such as energy use and human vulnerability to extreme heat have to be considered in the cooling-water use tradeoff, especially under the uncertainties of future climate change.
