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 …
Spatial And Temporal Intricacies Of Natural Resource Use: Studies In Water, Forests, And Hydrocarbons, Dadhi Adhikari
Spatial And Temporal Intricacies Of Natural Resource Use: Studies In Water, Forests, And Hydrocarbons, Dadhi Adhikari
Economics ETDs
This dissertation examines spatial and temporal impacts of natural resource use. The second chapter integrates hydrological and economic systems to examine the impact of drought on these two systems and explores the spatial impact of policies aimed to mitigate the drought impact. The systems dynamics model developed for this chapter simultaneously considers the physical hydrology in the Middle Rio Grande water basin in New Mexico, the engineered water management system, and a behavioral model of residential water demand for three cities: Albuquerque, Rio Rancho, and Santa Fe, New Mexico. The simulation results showed that droughts that occur in later periods, …
