Student Publications [Scholarly]
Climate-induced drought has become a growing concern across South Asia as rising temperatures and monsoon variability intensify hydroclimatic stress. This study evaluates historical (1979–2014) and future (2015–2100) hydroclimatic conditions in Rangpur using observed data and CanESM5 projections for three CMIP6 scenarios (SSP1-1.9, SSP2-2.6, SSP5-8.5). Multi-scale Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) were applied to detect droughts, while Tmax and Tmin Z-scores quantified heat anomalies and compound drought–temperature events. Historical records show strong rainfall variability with no significant long-term trend, but significant warming particularly in Tmin indicating increasing evaporative demand. Future projections reveal moderate precipitation increases (+ …

The U.S. Forest Monitor: Establishing A Historical Baseline For The Drivers And Climate Impacts Of Permanent Forest Loss, Christopher A. Williams, Natalia Hasler
Geography
This report introduces the U.S. Forest Monitor, a new system for tracking permanent forest conversion across the United States and reveals that forest loss is occurring at a significant and increasing scale. The burden of forest loss is unevenly distributed with 11 states representing 70% of all loss nationally. Forestland provides critical benefits including habitat and biodiversity, clean water and air, outdoor recreation, healthy soils, and climate regulation. Forests today face many threats, including fire, pest outbreaks and other stressors. Permanent deforestation, the focus of this report, involves the clearing of forests for another land use – like development and …

Where Do I Live, Again?: Finding Kentucky Geographic Information, Kurt X. Metzmeier
Brandeis School of Law Faculty Scholarship
Since the foundation of the United States, Americans have surveyed and recorded deeds to their properties in the county where they resided. However, until recently, those property surveys, as well as county maps, were the product of human surveyors drawing lines on paper. Only in the late 20th century, when satellites began surveying the globe and the internet made information readily accessible, did human maps give way to geographic information systems (GIS). This article surveys the GIS systems available to Louisville lawyers.

Tornado Impacts: St. Louis Neighborhoods And Physical Environment, Jeremiah J. Dyson, Kymberli Philpott, Ricardo Belle, Jamilah Bracely, Will Ranney, Cornell Evans
Undergraduate Research Symposium
This work explores the aftermath of the St. Louis May tornado last year that impacted parts of the area. Many homes, forests, properties, and other spaces such as wildlife habitats were destroyed. Through field explorations, geospatial technology, interviews, documentation, and comparing data, as a group we aimed to gain a better understanding of the geographic and sociological impact of the tornado, and the steps taken to help rebuild. With this project in mind, this work is also an explanation on what the preventative measures are to avoid mass destruction in natural disasters.

Terrestrial ecosystem regulation of carbon and water fluxes is critical for constraining climate–biosphere feedbacks but remains poorly quantified across space and time. Here, we evaluate whether co-located observations from NASA's Orbiting Carbon Observatory-3 (OCO-3) and the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) can reproduce ecosystem water use efficiency (WUE) dynamics observed at FLUXNET sites across temporal scales, vegetation types, climates, and drought conditions. We created the ECOCO3 data set, which harmonizes OCO-3 and ECOSTRESS observations in space and time. ECOCO3 captures broad seasonal and diurnal carbon and water flux patterns including midday drought responses. Sampling sensitivity analysis …

Extensive evidence demonstrates that people from minority backgrounds often face unequal exposure to extreme heat and have less access to green space that can provide cooling relief. What is less clear is whether these inequities extend to students on school playgrounds, where high temperatures can affect physical health, social and emotional well-being, and learning. We paired high resolution, satellite remote sensing surface temperature data for all 615 of the public schools in Orange County, California (serving ca. 450,000 students) with data on neighborhood household income, race/ethnicity of school enrollment, distance from the coast, and Normalized Difference Vegetation Index as a …

Nepal’s catastrophic 26 August 2026 Bhote Koshi–Trishuli flood should be understood not only as a humanitarian tragedy but also as a potentially major turning point in updating national settlement and reconstruction policy. Engineers and scientists have described the floods as a glacier–bedrock collapse that triggered an ice-rock avalanche and debris flow. As per the live updates on September 7, 2026, the total death toll was 1,355, and 4,996 people were missing (The Hindu, 2026). Indian and Nepali rescuers worked urgently to locate and rescue people buried under hydropower tunnels, buildings, mud, and landslide debris.

On the morning of 26 August 2026, the mountains above Nepal’s northern frontier delivered a disaster of almost unimaginable speed and scale. A massive mass of ice, rock, and sediment detached in the high Himalayan terrain near the Nepal–Tibet border, descended roughly 1,200 metres, interacted with the Lhende Khola system, and generated a debris-rich flood that surged through the Bhote Koshi and Trishuli river corridors, destroying settlements, markets, roads, bridges, hydropower facilities, and an international border crossing and transforming them into fields of mud, boulders, and wreckage within minutes (ICIMOD, 2026b; Reuters, 2026a). Satellite analysis indicates that a substantial section …

Geography Faculty Publications and Presentations
Most research into post-fire geomorphology has been conducted in regions with frequent fire, such as in dry Mediterranean and temperate climates and less has been conducted in wet forests where wildfire is now expanding with climate change. Because climate, soils, topography, vegetation, management legacies and fire history influence post-fire geomorphic processes, research into post-fire erosion and debris flow hazards across a broader set of climatologies is needed. The western Pacific Northwest (wPNW) of the United States is susceptible to multiple types of post-fire debris flows (i.e. shallow landslide-initiated and runoff-generated) that can be initiated by longer-duration lower-intensity rainfall compared to …

Modeling Bald Eagle Habitat Suitability In The Del Rio Springs Ecosystem Using Lidar And Spatial Analysis, Noah Morales, Hank Vincent, Ronny Schroeder
Modeling Bald Eagle Habitat Suitability In The Del Rio Springs Ecosystem Using Lidar And Spatial Analysis, Noah Morales, Hank Vincent, Ronny Schroeder
Student Works
This study expands upon prior research that utilized NDVI-based hotspot analysis from UAS and satellite imagery (Morales et al. 2026) to identify potential bald eagle nesting and foraging areas. While NDVI effectively captures vegetation density, it does not distinguish between vegetation types or landscape structural characteristics necessary for nesting. To address this limitation, this research integrates LiDAR-derived canopy height, terrain slope, and proximity to stream networks to develop a more refined habitat suitability model within the Del Rio Springs ecosystem.
Airborne LiDAR data were used to generate Digital Surface Models (DSM) and Digital Elevation Models (DEM), which were employed to …

Gis Methods To Distinguish Between Land Changes From Smallholder Agriculture And Mining In A Time Series For A Tropical Protected Area Forest, Pacifique Mubamba Madibi, Jean-Paul Kibambe Lubamba, Aiyin Zhang, Robert Gilmore Pontius
Geography
Tropical protected areas face pressures from smallholder agriculture and illegal mining, yet many monitoring approaches reduce these dynamics to net forest loss, obscuring whether change is alternating or persistent. In the Okapi Wildlife Reserve, Democratic Republic of the Congo, where the zoning plan allows only nonperennial crops in agriculture zones and forbids mining throughout the reserve, we analyzed annual Joint Research Centre–Tropical Moist Forest maps from 2000 to 2024 at 30 m spatial resolution. We applied Trajectory Analysis and DynamicPATCH across three study zones: agriculture, mining, and hunting–conservation. Trajectory Analysis classifies each pixel’s twenty-five-year non-forest time series into categories such …

The Timing Of Albedo Declines With Reforestation, Christopher A. Williams, Surendra Shrestha, Susan Cook-Patton, Natalia Hasler, Drew E. Terasaki-Hart, Samantha Yeo
Geography
Reforestation is a leading climate solution for removing carbon dioxide from the atmosphere, but generally decreases surface albedo, which diminishes its climate mitigation value. Knowing how quickly this albedo effect unfolds relative to carbon removal is critical for planning climate mitigation actions, yet the temporal changes in albedo are poorly described. This study uses satellite observations to characterize temporal changes in albedo with stand development for different forest types and ecoclimatic settings around the world. We find that about half of the climate warming effect from decreased albedo occurs within 40 years, but that it takes anywhere from 50 to …
Legal Geographies Of The Public Trust Doctrine, Alida Cantor, John P. Casellas Connors, Elizabeth Carlino
Legal Geographies Of The Public Trust Doctrine, Alida Cantor, John P. Casellas Connors, Elizabeth Carlino
Geography Faculty Publications and Presentations
The Public Trust Doctrine (PTD) is a legal principle that recognizes a duty of the government to hold certain natural resources in trust for public benefit. The doctrine has been extended within the United States to address issues of water, coastal access, wildlife conservation, and climate change. Its implementation is spatially uneven and subjective, however, raising geographic questions around scale, power, and political economy. This article uses a legal geographic approach to understand the PTD. Focusing on water, wildlife, and atmospheric resources, we analyze themes of scale and jurisdiction, property and commons, and legal and environmental subjectivity. We argue that …

Morphometric Analysis Of Gypsum Depressions Using Drone Imagery At Sinkhole Flat, Eddy County, New Mexico, Usa, Michael Sean Chenoweth
Research, Publications & Creative Work
Morphometric analysis is conducted on five karst depressions in Permian-age gypsum of southeast New Mexico. These depressions take on the form of classically shaped blind valleys and sinkholes. Blind valleys in this study are disappearing surface streams composed of multiple tributaries that connect to the main trunk channel leading to a cave entrance. A visible light (RGB) sensor mounted on a quadcopter is used to collect aerial imagery for karst depression mapping and analysis. Field measurements were taken for each depression for comparison with the drone imagery and its derivative layers such as digital elevation model (DEM) and slope. Drone …

Digital platform capitalism depends on geographic data to connect users with nearby goods and services, thus playing a role in both representing and shaping commercial landscapes. OpenStreetMap (OSM) represents a vast and low-cost geographic data source for platform capitalism; however, OSM is crowdsourced and exhibits uneven development across space, especially in rural areas. OSM researchers have observed that the map is built by a mix of local and remote volunteers, as well as corporate editors paid to identify and fill data gaps; however, deeper place-based inquiries are needed in order to better understand the process by which OSM contributors grow …

Institute for ECHO Articles and Research
The increasing frequency of wildfires under a changing climate has led to extensive ecosystem destruction, highlighting the need for reliable burned area assessment using satellite imagery. Single-satellite data are constrained by observation gaps and interference from smoke and clouds, whereas multi-satellite data fusion can mitigate these limitations. Nonetheless, the fusion techniques still encounter challenges such as spatial information loss from resolution differences and cross-satellite domain mismatch. This study presents a burned area mapping framework that integrates super-resolution (SR) with transfer learning to address spatial and domain gaps in multi-satellite data. Specifically, Landsat-8 imagery is super-resolved to 7.5 m resolution, and …

Nasa’S Ecostress Satellite Reveals Widespread Midday Depression In Ecosystem Evapotranspiration, Jingyi Bu, Jingfeng Xiao, Joshua B. Fisher, Yiqi Luo
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Plants often exhibit a midday depression in water use (i.e., transpiration), reflecting a constraint on their ability to sustain maximum water transport, which may occur at the cost of reduced photosynthesis. Eddy covariance observations and geostationary satellites cannot quantify this widespread phenomenon globally while resolving fine-scale spatial variability. Using evapotranspiration measurements from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) and machine learning, we quantify the global distribution of midday depression in evapotranspiration. Midday depression primarily occurs during peak-growing seasons in temperate zones and dry periods in the tropics, with a morning shift of the peak evapotranspiration time …

Blue Space As Amenity And Disamenity: Disparity In Interstitial Water Bodies, Mara Pirone
Geography Honors Projects
Access to environmental amenities is distributed unevenly across urban areas, often due to discriminatory institutional practices such as redlining and racial covenants. Urban blue spaces (lakes, streams, rivers) can serve as either an environmental amenity or dis-amenity, depending on development and investment strategies. This paper explores how institutional racism, measured by variables such as historic redlining and racial covenant practices, shapes access to blue space as an amenity in the Twin Cities. Our results show that access to large, well-maintained, and well-invested blue space is distributed unevenly. Studying this relationship shows how cities continue to promote environmental injustice in interstitial …

Covid-19, Politicization, And Vaccine Hesitancy: A Spatiotemporal Analysis Of Non-Medical Exemptions In Minnesota, 2014-2024, Benjamin Arnold
Geography Honors Projects
Vaccination rates have declined due to the growing hesitancy by many parents to vaccinate their children, signified by an increasing amount of non-medical exemptions. While there has been previous spatial analysis of exemption patterns as a threat to herd immunity, there has not been much post-COVID. This analysis provides a modern analysis of changing exemption clustering in Minnesota, while also considering the impact of public health being increasingly politicized. We used kindergarten vaccination data for 1475 elementary schools to analyze the evolution of clustering and predictors of NMEs across space and time in Minnesota, from 2014 to 2024.
