Innovative Measure On Achieving Common Prosperity: Carbon Transfer Payment, Peili Lu, Lanling Peng, Jiaqi Shen, Yanrui Jin, Yong Geng

Bulletin of Chinese Academy of Sciences (Chinese Version)

To achieve carbon peak and carbon neutrality, as well as common prosperity, is the key decision of the Chinese government. By addressing coordinated regional development and based upon balanced and reasonable distribution of income and carbon emission rights principles, the study aims to develop an equilibrium model to achieve regional carbon transfer payment. Carbon transfer payment can help adjust regional fiscal revenues so that the income distribution system is more in line with the scientific normal distribution characteristics under the common prosperity goal. Such a measure can address both equity and efficiency, balance carbon emission rights and development rights, contribute …

Evaluating The Sensitivity Of Heatwave Definitions Among North Carolina Physiographic Regions, Jagadeesh Puvvula, Azar M Abadi, Kathryn C. Conlon, Jared J. Rennie, Hunter Jones, Jesse E. Bell

School of Natural Resources: Faculty Publications

Exposure to extreme heat is a known risk factor that is associated with increased heat-related illness (HRI) outcomes. The relevance of heat wave definitions (HWDs) could change across health conditions and geographies due to the heterogenous climate profile. This study compared the sensitivity of 28 HWDs associated with HRI emergency department visits over five summer seasons (2011–2016), stratified by two physiographic regions (Coastal and Piedmont) in North Carolina. The HRI rate ratios associated with heat waves were estimated using the generalized linear regression framework assuming a negative binomial distribution. We compared the Akaike Information Criterion (AIC) values across the HWDs …

Spatio-Temporal Changes In Vegetation In The Last Two Decades (2001–2020) In The Beijing–Tianjin–Hebei Region, Yuan Zou, Wei Chen, Siliang Li, Tiejun Wang, Le Yu, Min Xu, Ramesh P. Singh, Cong-Qiang Liu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

In terrestrial ecosystems, vegetation is sensitive to climate change and human activities. Its spatial-temporal changes also affect the ecological and social environment. In this paper, we considered the Beijing–Tianjin–Hebei region to study the spatio-temporal vegetation patterns. The detailed analysis of a moderate-resolution imaging spectroradiometer (MODIS) data were carried out through the Google Earth Engine (GEE) platform. Our results show a slow and tortuous upward trend in the average leaf area index (LAI) in the study region for the periods 2001–2020. Specifically, Beijing had the highest LAI value, with an average of 1.64 over twenty years, followed by Hebei (1.30) and …

Assessing The Risk Of Land Subsidence In The Lower Limpopo River Basin, Mozambique With Remote Sensing, Gabriella Zuccolotto

Electronic Theses and Dissertations

Land subsidence is a threat to coastal cities around the world. In the lower Limpopo River Basin, the presence of compaction-prone alluvial sediments, groundwater use, and reports of saltwater intrusion suggest that subsidence could be occurring. Using interferometric synthetic aperture radar (InSAR) from Sentinel-1, combined with in-situ sea level and river height measurements, this study aims to determine if land subsidence could contribute to increased saltwater intrusion. InSAR results indicate that subsidence in the lower Limpopo River valley has occurred at an average rate of -2.98 cm/yr based on data from the dry seasons (May to October) of 2017-2021. River …

Perspectives On Sustainability In Short-Term Faculty-Led Programs, Amanda Staton

Capstone Collection

Sustainability is a relatively new topic to the field of International Education. Despite this, its importance is tantamount for the continuation of the industry for future generations. The industry’s significant negative environmental impacts from international student mobility poses a real barrier to the continuation of the industry due to climate change. This research emerged due to the lack of existing research on sustainability in Study Abroad, especially short-term faculty-led programs, which are currently the most popular modality of Study Abroad. Short-term faculty-led programs currently hold a reputation in existing literature for being the most unsustainable form of Study Aboard with …

Social Equity Is Key To Sustainable Ocean Governance, Katherine M. Crosman, Edward H. Allison, Yoshitaka Ota, Andrés M. Cisneros-Montemayor, Gerald G. Singh, Wilf Swartz, Megan Bailey, Kate M. Barclay, Grant Blume, Mathieu Colléter, Michael Fabinyi, Elaine M. Faustman, Russell Fielding

Anthropology and Geography

Calls to address social equity in ocean governance are expanding. Yet ‘equity’ is seldom clearly defined. Here we present a framework to support contextually-informed assessment of equity in ocean governance. Guiding questions include: (1) Where and (2) Why is equity being examined? (3) Equity for or amongst Whom? (4) What is being distributed? (5) When is equity considered? And (6) How do governance structures impact equity? The framework supports consistent operationalization of equity, challenges oversimplification, and allows evaluation of progress. It is a step toward securing the equitable ocean governance already reflected in national and international commitments.

A Decade Review Of Disease Surveillance Research Trends In The International Journal Of Health Geographics (2009 To 2018), Rose Jimenez, Paradorn Wongchanapai

Publications and Research

The field of health geographics is rapidly growing in its methods and epistemologies. This is a review of the open-source journal International Journal of Health Geographics, and the trends in disease surveillance over ten years (2009-2018). Drawing from research review methodologies, we wrote a Python script to quantify research trends within the field of geographic disease surveillance, finding many articles focusing on population health, techniques of GIS, qualitative techniques, and geospatial technology for health monitoring. This was foundational in conducting an in-depth qualitative lexical analysis of article content and epistemologies. Overall, we concluded that over the time period, the …

Low Levels Of Hybridization Between Sympatric Cold-Water-Adapted Arctic Cod And Polar Cod In The Beaufort Sea Confirm Genetic Distinctiveness, Robert E. Wilson, Sarah A. Sonsthagen, Philip Lavretsky, Andrew Majewski, Einar Árnason, Katrín Halldórsdóttir, Axel W. Einarsson, Kate Wedemeyer, Sandra L. Talbot

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

As marine ecosystems respond to climate change and other stressors, it is necessary to evaluate current and past hybridization events to gain insight on the outcomes and drivers of such events. Ancestral introgression within the gadids has been suggested to allow cod to inhabit a variety of habitats. Little attention has been given to contemporary hybridization, especially within cold-water-adapted cod (Boreogadus saida Lepechin, 1774 and Arctogadus glacialis Peters, 1872). We used whole-genome, restriction-site associated, and mitochondrial sequence data to explore the degree and direction of hybridization between these species where previous hybridization had not been reported. Although nearly identical …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard Melstrom, Mark A. Kaemingk, John C. Whitehead, Nicholas W. Cole, Christopher J. Chizinski, Kevin L. Pope

School of Environmental Sustainability: Faculty Publications and Other Works

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Genetic Freedom Of The Seas In The Age Of Extractivism: Marine Genetic Resources In Areas Beyond National Jurisdiction, Irus Braverman

Contributions to Books

Published as Chapter 4 in Laws of the Sea: Interdisciplinary Currents, Irus Braverman, ed.

Areas beyond national jurisdiction are the largest environment on earth and marine genetic resources are its new, and perhaps final, frontier. It is no wonder, then, that the scope and protection of marine genetic resources in this oceanic space have been hotly contested and that a new doctrine for ocean governance has been coined in this context: mare geneticum. This chapter examines different definitions of marine genetic resources debated in the ongoing treaty negotiations over areas beyond national jurisdiction (the BBNJ), the conflicting interests involved, and …

Amphibious Legal Geographies: Toward Land–Sea Regimes, Irus Braverman

Contributions to Books

Published as ine introduction to Laws of the Sea: Interdisciplinary Currents, Irus Braverman, ed.

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the juridical thinking that has enshrined the land/sea divide into contemporary governmental infrastructures, disciplinary traditions, and regulatory apparatuses, and charts the disastrous implications that such a legal fixation on the land/sea binary has wrought on human and other-than-human lifeworlds. As the collection proceeds, a second broad theme emerges, building on the first: when one rethinks the abstraction of law as played out on the ground, the …

Heavy Metal Levels And Sources In Suspended Particulate Matters Of The Glacier Watersheds In Northeast Tibetan Plateau, Rui Wu, Zhiwen Dong, Xiping Cheng, Janice Brahney, Xiaoyu Jiao, Lihua Wu

Watershed Sciences Faculty Publications

This study collected summer meltwater runoff samples from several glacier watersheds of the northeast Tibetan Plateau during June-July 2017, and measured the concentrations of 17 trace elements (Li, Be, Sc, V, Cr, Co, Ni, Cu, Zn, Ga, Rb, Mo, Cd, In, Sb, Cs, Ba) in meltwater suspended particulate matter (SPM), in order to reveal the elemental concentration, spatial distribution, and water quality in remote glacier watershed under regional anthropogenic activities. Results showed that, the concentration of heavy metal elements was relatively high in Yuzhufeng Glacier basin, ranging from 0.57 μg/L (In) to 1,551.6 μg/L (Ba), whereas in Qiyi Glacier basin …

Rock Climbing And Conservation In Land Management: Can They Coexist?, Marissa Heller

Geography ETDs

As participation in outdoor recreation is growing in the U.S., a dilemma is presented for conservation planners and land area managers who must manage the increasing demand for recreation while simultaneously working to protect species. Rock climbers and other outdoor recreationalists have asserted that a relationship exists between recreation and the conservation of public lands. However, mounting evidence suggests that rock climbing continues to cause a multitude of negative impacts to ecosystems. Here, I investigate the extent to which land management practices allow for rock climbing and conservation to coexist, and how it is that well developed plans protect ecologically …

An Integrated Gis & Flood Vulnerability Index Approach To Evaluating Risk & Environmental Equity In Urban Karst Communities, Chloe Cooper

Masters Theses & Specialist Projects

This study examines how the usage of an integrated GIS (Geographic Information Systems), flood vulnerability assessment, and management approaches can aid in hazard response planning in karst groundwater systems, particularly in urban environments. In order to also better understand the impacts of flood events on socially vulnerable groups, this research was focused on historically excluded communities. Additionally, place-based vulnerabilities were primarily assessed based upon three main factors in the vulnerability framework and how these components intersect: social, environmental conditions, and economic. By understanding which areas of the City of Bowling Green, an iconic urban karst area, are most vulnerable and …

Fire And Human Management Of Late Holocene Ecosystems In Southern Africa, Benjamin Davies, Mitchell J. Power, David R. Braun, Matthew J. Douglass, Stella G. Mosher, Lynne J. Quick, Irene Esteban, Judith Sealy, John Parkington, J. Tyler Faith

School of Natural Resources: Faculty Publications

Globally, fire is a primary agent for modifying environments through the long-term coupling of human and natural systems. In southern Africa, control of fire by humans has been documented since the late Middle Pleistocene, though it is unclear when or if anthropogenic burning led to fundamental shifts in the region's fire regimes. To identify potential periods of broad-scale anthropogenic burning, we analyze aggregated Holocene charcoal sequences across southern Africa, which we compare to paleoclimate records and archaeological data. We show climate-concordant variability in mid-Holocene fire across much of the subcontinent. However, increased regional fire activity during the late Holocene (~2000 …

Analysis Of Seismicity And Related Seismic Risk In Muslim Countries: Case Studies From Afghanistan And Pakistan, Ikramuddin Bahram

Graduate Theses and Dissertations

How communities respond to a natural hazard is influenced by how they perceive it. This dissertation evaluated the gap between intent and action regarding earthquake hazards in Muslim countries with a focus on Afghanistan and Pakistan. Cultural biases provided predictions of risk perceptions and risk-taking preferences that were often more powerful than measures of knowledge and experience. In Muslim communities, perception of risk was influenced by the teachings of Islam and related rituals, traditions, and culture.

This study evaluated the seismicity and earthquake hazard in Afghanistan and Pakistan. Assessments of seismic risk and perception of danger were conducted to examine …

Integrated Assessment Of Urban Overheating Impacts On Human Life, N. Nazarian, E. S. Krayenhoff, B. Bechtel, D. M. Hondula, R. Paolini, J. Vanos, T. Cheung, Winston T. L. Chow, Et Al

Research Collection College of Integrative Studies

Urban overheating, driven by global climate change and urban development, is a major contemporary challenge that substantially impacts urban livability and sustainability. Overheating represents a multifaceted threat to the well-being, performance, and health of individuals as well as the energy efficiency and economy of cities, and it is influenced by complex interactions between building, city, and global scale climates. In recent decades, extensive discipline-specific research has characterized urban heat and assessed its implications on human life, including ongoing efforts to bridge neighboring disciplines. The research horizon now encompasses complex problems involving a wide range of disciplines, and therefore comprehensive and …

Modern Pyromes: Biogeographical Patterns Of Fire Characteristics Across The Contiguous United States, Megan E. Cattau, Adam Mahood, Jennifer K. Balch, Carol Wessman

Human-Environment Systems Research Center Faculty Publications and Presentations

In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to characterize the spatiotemporal patterns of contemporary fire characteristics across the contiguous United States (CONUS). We derived fire variables based on frequency, fire radiative power (FRP), event size, burned area, and season length from satellite-derived fire products and a government records database on a 50 km grid (1984–2020). We used k-means clustering to create a hierarchical classification scheme of areas with relatively homogeneous fire characteristics, or modern …

Human-Wildlife Coexistence With Coyotes In Los Angeles County, Ca And Cook County, Il, Alan Eapen

Legacy Theses & Dissertations (2009 - 2024)

The expansion of coyotes (Canis latrans) into urban and suburban areas where human concentration is high has led to human-coyote conflicts often leading to increased management actions against coyotes. Recently in Los Angeles and Cook Counties, municipalities have developed coyote management plans to foster human-wildlife coexistence in an effort to reduce conflict, an emerging concept that promotes the cohabitation of humans and animals in shared landscapes. The thesis investigates coyote management plans and policies concerning human-coyote interactions in Los Angeles and Cook Counties to address human-wildlife. Using a case study analysis of Los Angeles and Cook Counties, this study analyzed …

Defining An Epidemiological Landscape That Connects Movement Ecology To Pathogen Transmission And Pace-Of-Life, Kezia Manlove, Mark Wilber, Lauren White, Guillaume Bastille-Rousseau, Anni Yang, Marie L.J. Gilbertson, Meggan E. Craft, Paul C. Cross, George Wittemyer, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Pathogen transmission depends on host density, mobility and contact. These components emerge from host and pathogen movements that themselves arise through interactions with the surrounding environment. The environment, the emergent host and pathogen movements, and the subsequent patterns of density, mobility and contact form an ‘epidemiological landscape’ connecting the environment to specific locations where transmissions occur. Conventionally, the epidemiological landscape has been described in terms of the geographical coordinates where hosts or pathogens are located. We advocate for an alternative approach that relates those locations to attributes of the local environment. Environmental descriptions can strengthen epidemiological forecasts by allowing for …

Conservation Conflict: Rare Plant Conservation And Energy Development And Potential In The Colorado Plateau, Joshua Carrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Colorado Plateau provides numerous sources of energy, particularly natural oil and gas. This energy potential is being actively extracted for consumption on both public and private lands. Elements of biodiversity (e.g., listed and sensitive plant and animal species) are distributed among all land tenures, yet the laws protecting them can vary depending if they occur on public, private, or tribal land. Therefore, it is necessary to understand the geographic ranges of threatened, endangered, and sensitive species and their relationship to land ownership to preserve habitat and conserve species populations. I developed species distribution models (SDMs) to examine the predicted …

Conservation Genetics Of A Declining Bumble Bee In Western North America; The Influence Of Geography, Dispersal Limitation, And Anthopogenic Activity, Ashley T. Rohde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conservation biology addresses the problem of species loss by identifying species in need of protection. Conservation biology has subfields to address different aspects of biodiversity loss, including genetics and sociology. I used genetic approaches to assess the conservation status of western bumble bees, a bumble bee species of conservation concern.

The western bumble bee is a bumble bee species that ranges from Alaska to New Mexico and as far east as Wyoming and Colorado. This species is disappearing in some places. It may soon be listed as endangered in the United States and is already listed as endangered in parts …

A Climate Of Confessionalization: Famine And Difference In The Late Ottoman Empire, Matthew Ghazarian

Environmental Science and Policy: Faculty Publications

After the 1877–78 Russo-Ottoman War, the Ottoman Empire saw the rise of ethnic and sectarian clashes in Anatolia, the Balkans, and elsewhere, and the task of explaining that rise remains unfinished. Many have examined the intellectual formations of ethnic and sectarian solidarities after 1878, but the availability of new ideas cannot alone account for their widespread uptake. Why after 1878 did ordinary people respond more to calls upon ethnic and sectarian solidarity? Drawing on sources surrounding the 1879 famine in the Ottoman East, this article steps away from imperial metropoles to examine overlapping environmental, financial, and technological disjunctures. Adopting the …

A Climate Resilience Research Renewal Agenda: Learning Lessons From The Covid-19 Pandemic For Urban Climate Resilience, Mark Pelling, Winston T. L. Chow, Eric Chu, Richard Dawson, David Dodman, Arabella Fraser, Bronwyn Hayward, Luna Khirfan, Timon Mcphearson, Anjal Prakash, Gina Ziervogel

Research Collection School of Social Sciences

Learning lessons from the COVID-19 pandemic opens an opportunity for enhanced research and action on inclusive urban resilience to climate change. Lessons and their implications are used to describe a climate resilience research renewal agenda. Three key lessons are identified. The first lesson is generic, that climate change risk coexists and interacts with other risks through overlapping social processes, conditions and decision-making contexts. Two further lessons are urban specific: that networks of connectivity bring risk as well as resilience and that overcrowding is a key indicator of the multiple determinants of vulnerability to both COVID-19 and climate change impacts. From …

El Niño And The Human-Environment Nexus: Drought And Vulnerability In Singapore 1877-1911, Fiona Williamson

Research Collection College of Integrative Studies

This chapter brings a climatic perspective to the study of Singaporean history by exploring the impacts of the strong El Niño inspired droughts of 1877, 1902 and 1911. The narrative focuses on unpacking the nexus of nature-inspired versus human-induced vulnerability to drought within the contexts of colonial urbanisation and looks at the short-to medium-term impacts of the events on society. It also explores how such events inspired new questions about the climate and regional teleconnections, as a wealth of evidence became available due to the increasingly connected nature of scientific institutions, scientific literature, and communications systems across the Indian Ocean …

Early Pleistocene Marine Isotope Stage (MIS)-31 (1.081–1.062 Ma) is a unique interval of extreme global warming, including evidence of a West Antarctic Ice Sheet (WAIS) collapse. Here we present a new 1,000-year resolution, spanning 1.110–1.030 Ma, diatom-based reconstruction of primary productivity, relative sea surface temperature changes, sea-ice proximity/open ocean conditions and diatom species absolute abundances during MIS-31, from the Scotia Sea (59°S) using deep-sea sediments collected during International Ocean Discovery Program (IODP) Expedition 382. The lower Jaramillo magnetic reversal (base of C1r.1n, 1.071 Ma) provides a robust and independent time-stratigraphic marker to correlate records from other drill cores in the …

The Changing Urban Forest In Gallup, New Mexico: Contextualizing Urban Tree Programs And Planning Processes, Joseph A. Scala

Geography ETDs

Tree plantings are often proposed as a solution to a variety of urban problems. The purpose of this project is to investigate the historical formation of urban tree cover in Gallup, New Mexico, and the extent to which urban tree plantings can benefit areas with inequitable urban tree distribution. To do this, I employ a mixed methods approach that includes correlation analysis, historical analysis, and analysis of urban tree canopy change from 1972-2005. The findings from this study indicate that Gallup’s history of tree plantings is heavily influenced by its history of economic development. Additionally, the findings demonstrate that if …
