Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie
Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie
Geography ETDs
In the western US, relationships between fire, vegetation, climate, and urban areas are dynamic and evolving. This work used a forest landscape model, LANDIS-II, informed by future climate scenarios and projections of urban expansion to understand wildfire interactions within projected Wildland Urban Interface (WUI) areas. This simulation showed that in both 2050 and 2100 +93% of the WUI in southern California experienced fire. Future work needs to be done in parametrizing forest biomass to ensure the validity of projections. Additionally, increasing each climate scenario model's replicates will create more accurate projections.
Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller
Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller
Geography ETDs
Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …

La Gota Que Colma La Caguama: Cummulative Tensions Transformed Into The Defense Of Water, Anthony J. Meluso

Making water management decisions is often where dreams and visions about potential futures are constructed and contested (Swengedouw 2015). However, in a globalized world, it is not well understood how people can challenge dominant paradigms to shape desirable futures when they are also complicit in, and dependent on existing structures (Arts & Buizer 2009; Emery, Perks, & Bracken 2013: Kleinschmit, Böcher, & Giessen 2009). This project examines a brewery conflict in the Mexicali Valley that provides an example of how protesters were able to challenge dominant assumptions about water management in a complex, globalized environment. I draw on Laclau’s (2005) …
Impact Of Drought On Land Cover Changes In Diné Bikéyah – A Study Through Remote Sensing, Anjanette A.J. Hawk
Impact Of Drought On Land Cover Changes In Diné Bikéyah – A Study Through Remote Sensing, Anjanette A.J. Hawk
Geography ETDs
This study identifies land cover changes associated with a ten-year drought period and discusses the importance of vegetation change in Diné Bikéyah, a semi-arid land located in a remote part of the southwestern United States (US). This study concludes that drought produced slight changes in vegetation within a 540 km2 study area in the Tselani-Cottonwood Chapter (TCC) in Diné Bikéyah. The data for this study consist of three Landsat images for the years 1998, 2002, and 2009. The methods used to analyze these Landsat images included image pre-processing, calculation of normalized difference vegetation index (NDVI) images, and supervised (maximum …
