Lightning-Ignited Wildfires In The Western United States: Ignition Precipitation And Associated Environmental Conditions, Dmitri Alexander Kalashnikov, John T. Abatzoglou, Paul Loikith, Nicholas J. Nauslar, Yianna Sotirios Bekris, Deepti Singh

Geography Faculty Publications and Presentations

Cloud-to-ground lightning with minimal rainfall (“dry” lightning) is a major wildfire ignition source in the western United States (WUS). Although dry lightning is commonly defined as occurring with <2.5 mm of daily-accumulated precipitation, a rigorous quantification of precipitation amounts concurrent with lightning-ignited wildfires (LIWs) is lacking. We combine wildfire, lightning and precipitation data sets to quantify these ignition precipitation amounts across ecoprovinces of the WUS. The median precipitation for all LIWs is 2.8 mm but varies with vegetation and fire characteristics. “Holdover” fires not detected until 2–5 days following ignition occur with significantly higher precipitation (5.1 mm) compared to fires detected promptly after ignition (2.5 mm), and with cooler and wetter environmental conditions. Further, there is substantial variation in precipitation associated with promptly-detected (1.7–4.6 mm) and holdover (3.0–7.7 mm) fires across ecoprovinces. Consequently, the widely-used 2.5 mm threshold does not fully capture lightning ignition risk and incorporating ecoprovince-specific precipitation amounts would better inform WUS wildfire prediction and management.

Yolov4_Cspbi: Enhanced Land Target Detection Model, Lirong Yin, Lei Wang, Jianqiang Li, Siyu Lu, Jiawei Tian, Zhengtong Yin, Shan Liu, Wenfeng Zheng

Faculty Publications

The identification of small land targets in remote sensing imagery has emerged as a significant research objective. Despite significant advancements in object detection strategies based on deep learning for visible remote sensing images, the performance of detecting a small and densely distributed number of small targets remains suboptimal. To address this issue, this study introduces an improved model named YOLOV4_CPSBi, based on the YOLOV4 architecture, specifically designed to enhance the detection capability of small land targets in remote sensing imagery. The proposed model enhances the traditional CSPNet by redefining its channel partitioning and integrating this enhanced structure into the neck …

‘Following The Line Of Least Resistance’: African American Women In Domestic Work, 1899–1940, Taylor Simsovic

Armstrong Undergraduate Journal of History

This paper examines the challenges faced by African American women employed in domestic service between 1899 and 1940, with a focus on how race, class, and gender intersected to shape their experiences. Specifically, the study investigates how these women continued to perform reproductive labor as they migrated from the South to Northern states during the Great Migration. Drawing on a range of primary and secondary sources, the analysis argues that Black women's persistent employment in undervalued labor within white American homes was driven by the mutually constitutive systems of capitalism, white supremacy, and patriarchy. These systems channeled Black women into …

Canary In The Forest?—Tree Mortality And Canopy Dieback Of Western Redcedar Linked To Drier And Warmer Summers, Robert A. Andrus, L. R. Peach, A. R. Cinquini, Joseph Hulbert, J. T. Yusi, Andres Holz, M. Fischer, Kevan B. Moffett, Multiple Additional Authors

Geography Faculty Publications and Presentations

Aim: Forest dieback is increasing from unfavourable climate conditions. Western redcedar (WRC)—a culturally, ecologically and economically important species—has recently experienced anomalously high mortality rates and partial canopy dieback. We investigated how WRC tree growth and dieback responded to climate variability and drought using tree-ring methods. Location: Pacific Northwest, USA. Taxon: Western redcedar (Thuja plicata). Methods: We collected tree cores from three tree health status groups (no canopy dieback, partial canopy dieback, and dead trees) at 11 sites in coastal (maritime climate) and interior (continental climate) WRC populations. From growth rates, we computed four growth indices that assessed the resilience to …

Settling Into Inequality: Resettled Afghans In The Washington Dc Metro Area, Harry Frey

Dissertations, Theses, and Capstone Projects

Since the Taliban returned to power in Afghanistan in August of 2021, nearly 90,000 Afghans who had fled their country have been resettled in the United States, constituting one of the largest groups of refugee arrivals in the U.S. in recent history. Working from a database I created from the administrative records of a non-profit refugee aid group, I use data and spatial analysis to examine the demographics of Afghans resettled in the DC metro area, the characteristics of the census tracts and counties in which they have been resettled, and their access to public transportation. I find that the …

Structural Tensions Limiting Success Of Infrastructure Upgrading: A Multi-Regime Perspective, George Kiambuthi Wainaina, Bernhard Truffer, James T. Murphy

Geography

Unfettered growth of slums is a daunting transition challenge and many upgrading programs fail to sustainably improve the livelihoods of slum residents. This paper elaborates a transitions perspective on structural tensions that may lead to success or failure of slum upgrading programs. We conceptualize slums as urban subsystems, governed by sociotechnical (infrastructure) and socioeconomic livelihood regimes (related to production and social reproduction). The framework permits examination of the tensions due to mis/alignments of rules associated with newly introduced infrastructures, and those that regulate existing production and social reproduction practices of slum residents. This approach extends transition studies by accounting for …

The Town That Built Its Own River: La Plaza Del Cerro At Taos County New Mexico, José A. Rivera Ph.D

Faculty Publications

Cerro is an unincorporated community in Taos County, New Mexico, and is situated near New Mexico State Highway 522 heading north to the Colorado border. Nearby is Cerro de Guadalupe, a peak that has an elevation of 8,796 feet and Cerro at 7,490 feet. The connection to Guadalupe Mountain gave the town its original name as “La Plaza del Cerro de Guadalupe.” Cerro was established in the early 1850s by settlers who arrived from nearby Questa and Taos. By itself, Guadalupe Mountain did not provide sufficient water to sustain an agrarian economy based on farming and livestock ranching as was …

Nonprofit Accountability: Effects Of Subsector On Online Accountability, Ibrahima F. Yaro, Trent A. Engbers

Midwest Social Sciences Journal

Scandals within the nonprofit sector over compensation and management have increased calls for nonprofits to demonstrate accountability. Many organizations have responded by disclosing information online and providing tools that allow web-based interactions with stakeholders. The literature on nonprofits’ online accountability has found that the level of nonprofit online accountability is affected by their size, age, asset, revenue, and location, but hasn’t been examined in terms of how subsector influences online accountability. Through a web-content analysis of fifty-five nonprofits, this research investigated how subsector (arts and culture, education, health, and human services) influences online accountability using a framework of four types …

A Mixed Methods Approach To Understanding The Links Between Mining, Climate Change And Selected Health Outcomes In India, Mary J. Cheruvillil

Whose Growth In Whose Planetary Boundaries? Decolonising Planetary Justice In The Anthropocene, Farhana Sultana

Geography and the Environment - All Scholarship

This critical analysis examines the geopolitics of planetary environmental injustice and the imperative for systems change to address the intertwined crises of climate breakdown and unsustainable economic growth. Climate breakdown has heightened attention to uneven anthropogenic use and abuse of the planet's biosphere and common pool resources. Recent arguments by climate scholars suggest that various planetary boundaries have already been breached, resulting in dramatic and harmful socio-ecological consequences. These trends raise crucial questions of equity and justice, especially concerning responsibilities and impacts. By centring Global South perspectives, prevailing ideologies promoting hyperconsumption, overproduction and waste are interrogated. The incommensurability of socioecological …

Methodological Analysis On Settler Territoriality And The Rise Of The Yellowstone Wild Bison Advocacy Movement, Red G.R. Burkett

Theses - ALL

Bison bison, also known as the North American Buffalo, are a keystone species of endemic megafauna in the Great Plains prairie ecosystem. Bison were driven nearly to extinction in the late 19th century when millions of buffalo were massacred by settlers in order to starve Indigenous civilians and force them onto federally-managed Reservations as a step in the centuries-long ethnic-cleansing of Turtle Island. Such genocidal methods were a primary tool in erasing the land claims of Indigenous nations and colonizing the territories of Indigenous communities who depended on bison as a primary source of food and materiel for social reproduction. …

Wildfire Risk Governance From The Bottom Up: Linking Local Planning Processes In Fragmented Landscapes, Matthew Hamilton, Max Nielsen-Pincus, Cody Evers

Environmental Science and Management Faculty Publications and Presentations

The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages among local-level risk mitigation planning processes. Improving resilience to the effects of environmental change requires a better understanding of factors that contribute to these linkages. Using data on the patterns of participation of 10,199 individual stakeholders in 837 community wildfire protection plans (CWPPs) within the western U.S., we document the emergence of a locally clustered but spatially extensive wildfire risk governance network. Our evaluation of factors that …

Urban Sustainability Implementation And Indicators In The United States: A Systematic Review, Heejun Chang, Arun Pallathadka, Idowu Ajibade

Geography Faculty Publications and Presentations

Urban sustainability is the goal of many cities in the world, yet very few have achieved a level of sustainability that goes beyond the most basic environmental objectives. The practice and assessment of sustainability implementation are greatly compounded by lack of funding, technical know-how, political will, and the power disparity between dominant institutions and marginalized communities. This systematic analysis of urban sustainability literature involved the review of 241 studies published between 2010 and 2022. We critically examined current debates and challenges in urban sustainability, identifying gaps and opportunities and providing recommendations for creating equitable, just, and sustainable urban futures. We …

Quantifying Damages To Soil Health And Emissions From Land Development In The State Of Illinois (Usa), Elena A. Mikhailova, Hamdi A. Zurqani, Zhenbang Hao, Mark A. Schlautman, Gregory C. Post, George B. Shepherd, Christopher C. Post, Renee M. Dixon

Geography Faculty Publications and Presentations

The concept of soil health is increasingly being used as an indicator for sustainable soil management and even includes legislative actions. Current applications of soil health often lack geospatial and monetary analyses of damages (e.g., land development), which can degrade soil health through loss of carbon (C) and productive soils. This study aims to evaluate the damages to soil health (e.g., soil C, the primary soil health indicator) attributed to land developments within the state of Illinois (IL) in the United States of America (USA). All land developments in IL can be associated with damages to soil health, with 13,361.0 …
