Enhancing Agricultural Sustainability Under Climate Change: A Multi-Scale Framework Integrating Climate Extremes, Resource Efficiency, And Data-Driven Modeling, Shahryar Fazli

Computational and Data Sciences (PhD) Dissertations

Agricultural systems are increasingly challenged by climate variability, where shifting temperature regimes, hydrological variability, and the rising frequency of compound and cascading extremes threaten global food security and resource sustainability. Addressing these challenges requires integrated frameworks that bridge biophysical monitoring, predictive modeling, and adaptive decision-making. This dissertation develops a data-driven, multi-scale framework to quantify and enhance agricultural resilience by integrating remote sensing, climate analytics, and machine learning across the United States, with a focus on California and the Western U.S.

First, hyperspectral and thermal remote sensing data from EMIT and OpenET are integrated to characterize crop nitrogen–water interactions and assess …

Long-Term Analysis Of Pm2.5 Elemental Composition And Source Contributions In Coastal Urban Environments Of Corpus Christi And Houston In Texas, Sai Deepak Pinakana, Jeremy A. Sarnat, Amit U. Raysoni

School of Earth, Environmental, & Marine Sciences Faculty Publications

Long-term assessments of fine particulate matter play a key role in identifying persistent and emerging emission contributors. Coastal urban areas are highly susceptible to transboundary dust and wildfire events in addition to local pollution sources. Multi-decadal assessments in these regions using chemical speciation data could offer insights into major pollutant sources and their trends. This study utilizes nearly two decades of PM2.5 elemental composition data at two major coastal cities in Texas: Houston and Corpus Christi. Fourteen trace elements were analyzed to characterize the seasonal variability and long-term source evolution using a combination of Spearman’s correlation analysis, principal component analysis, …

Seasonal Variations In Radar Backscatter And Corn Vegetation In The South Fork Iowa River Watershed During The Growing Season Of 2025, Monika Bhusal

Scholars Week

Remote sensing provides complementary information on crop development and surface conditions, but radar backscatter over agricultural areas can be influenced by vegetation and soil characteristics. This study examines seasonal relationships between Sentinel-1 radar backscatter and Landsat-derived vegetation greenness over corn-growing areas in the South Fork Iowa River Watershed, Iowa, during the 2025 growing season. Landsat 8/9 was used to derive the Normalized Difference Vegetation Index (NDVI), while OPERA RTC-S1 imagery provided VV and VH backscatter and a VH/VV polarization measure. USDA Cropland Data Layer was used to identify corn growing areas, and analysis was restricted to areas with common satellite …

Summit County, Utah: Changes To Climate, Snowpack, And Wildfire (1979-2025), Scott Hotaling, Gordon O. Gianniny, Joseph D. Birch, Elizabeth Cohen, Kendall Becker

All Current Publications

Summit County is climatically unique from the rest of Utah due to its high mean elevation. It’s also economically unique, with world-class ski resorts near working agricultural lands. In this fact sheet, we synthesize how Summit County’s environment is changing, with an emphasis on the last 50 years. We focus on changes in temperature, precipitation, and snowpack; growing season length; and wildfire because of their impacts on the economy, natural resources, and local communities' well-being. Our goal is to support the region's future planning efforts. To that end, we highlight risks to Summit County’s future and opportunities that may arise …

Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith

International Journal of Speleology

Tourist activity is widely recognised as a source of cave microclimate disturbance, yet visitor-induced variability is difficult to distinguish from natural environmental fluctuations. The coronavirus pandemic created a natural experiment at Poole’s Cavern, United Kingdom, in which periods of complete closure could be compared with contrasting visitor access regimes. Two years of high resolution temperature records from six monitoring points were analysed. Harmonic regression and a state space model removed deterministic diurnal cycles and lower frequency temperature variability. The remaining residual variability differed systematically among visitor access regimes and between daytime and nighttime conditions. Spectral analysis of the residuals identified …

Harmful Algal Bloom Monitoring In South Florida Using Water And Aerosol Payloads On Uncrewed Aircraft, Kayla D. Taylor, Justin Fratto, Avinash Muthu Krishnan, David Zink, Blake Neal, Jose Cabrera, Emel Sen-Kilic, Marc Compere, Kevin Adkins

Student Works

Harmful algal blooms (HABs) threaten aquatic ecosystems, public health, and tourism and fishing industries throughout the United States, including Florida. Because HABs can develop and spread rapidly, geographically representative sampling efforts can be very difficult and labor-intensive, and traditional monitoring methods, such as satellite-based remote sensing, often lack the spatiotemporal resolution needed to characterize bloom dynamics. This project, funded by the Environmental Protection Agency (Grant No. 05D36825), aims to develop an uncrewed aircraft (UA)-based water and aerosol sampling approach to improve HAB monitoring and support prediction and mitigation efforts. One year into our funding period, we have integrated a multi-depth, …
