No One Size Fits All: Key Debates In Transnationalism Research, Chi Hong Nguyen

Essays in Education

Migration is often examined through different theories and approaches such as cultural theories, policy and economic frameworks and transnationalism. Most of these approaches unpack the key components of migration that include effects of social structures on agency, influences of transnational ties, migrants’ successes and lives in limbo as well as cultural norms and gender roles. These have succeeded in offering a well-informed understanding of migration as embodied processes that are formed by migrants’ interactions with the surrounding world. As an embodied approach, transnationalism looks into various aspects of migrants’ lives across space and time. It entails various units of analysis. …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft

Human–Wildlife Interactions

Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km². Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …

Advancing Best Practices For Aversion Conditioning (Humane Hazing) To Mitigate Human–Coyote Conflicts In Urban Areas, Lesley Sampson, Lauren Van Patter

Human–Wildlife Interactions

Coyotes (Canis latrans) are now recognized as a permanent feature in urban environments across much of North America. Behavioral aversion conditioning, or humane hazing, is increasingly advocated as an effective and compassionate alternative to wildlife management strategies, such as trap and removal. Given a growing public interest in humane hazing, there is a need to synthesize the science regarding methods, outcomes, efficacy, and other relevant considerations to better manage human–coyote conflicts in urban areas. This paper was prepared as an outcome of a workshop held in July 2019 by Coyote Watch Canada (CWC) to synthesize the literature on …

Environmentally Clean Access To Antarctic Subglacial Aquatic Environments, Alexander B. Michaud, Trista (Vick-Majors, Amanda M. Achberger, Mark L. Skidmore, Brent C. Christner, Martyn Tranter, John C. Priscu

Faculty Publications

Subglacial Antarctic aquatic environments are important targets for scientific exploration due to the unique ecosystems they support and their sediments containing palaeoenvironmental records. Directly accessing these environments while preventing forward contamination and demonstrating that it has not been introduced is logistically challenging. The Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project designed, tested and implemented a microbiologically and chemically clean method of hot-water drilling that was subsequently used to access subglacial aquatic environments. We report microbiological and biogeochemical data collected from the drilling system and underlying water columns during sub-ice explorations beneath the McMurdo and Ross ice shelves and …

Linking Irrigation To Landslides In Franklin County, Washington, Eric Savaria

Departmental Honors & Graduate Capstone Projects

Landslides occur when a slope is unstable and collapses with different contributing and mediating factors to slope instability, including human activity. This study evaluates the association between the occurrence of landslides and irrigation in Franklin County, Washington. The study sought to evaluate whether irrigation can be linked to an increase in the occurrence of landslide events within Franklin County. The study area was divided into a ‘treatment site’ and several ‘control sites.’ The treatment site is located in Franklin County where irrigation has occurred near the cliff, while the control sites are sloped and non-irrigated areas outside of Franklin County. …

Landscape Fragmentation In Coffee Agroecological Subzones In Central Kenya: A Multiscale Remote Sensing Approach, Gladys Mosomtai, John Odindi, Elfatih M. Abdel-Rahman, Régis Babin, Pinard Fabrice, Onisimo Mutanga, Henri E.Z. Tonnang, Guillaume David, Tobias Landmann

All Peer-Reviewed Publications

Smallholder agroecological subzones (AEsZs) produce an array of crops occupying large areas throughout Africa but remain largely unmapped. We explored multisource satellite datasets to produce a seamless land-use and land-cover (LULC) and fragmentation dataset for upper midland (UM1 to UM4) AEsZs in central Kenya. Specifically, the utility of PlanetScope, Sentinel 2, and Landsat 8 images for mapping coffee-based landscape were tested using a random forest (RF) classifier. Vegetation indices, texture variables, and wavelength bands from all satellite data were used as inputs in generating four RF models. A LULC baseline map was produced that was further analyzed using FRAGSTAT to …

Phenology Of Short Vegetation Cycles In A Kenyan Rangeland From Planetscope And Sentinel-2, Yan Cheng, Anton Vrieling, Francesco Fava, Michele Meroni, Michael Marshall, Stella Gachoki

All Peer-Reviewed Publications

The short revisit times afforded by recently-deployed optical satellite sensors that acquire 3–30 m resolution imagery provide new opportunities to study seasonal vegetation dynamics. Previous studies demonstrated a successful retrieval of phenology with Sentinel-2 for relatively stable annual growing seasons. In semi-arid East Africa however, vegetation responds rapidly to a concentration of rainfall over short periods and consequently is subject to strong interannual variability. Obtaining a sufficient density of cloud-free acquisitions to accurately describe these short vegetation cycles is therefore challenging. The objective of this study is to evaluate if data from two satellite constellations, i.e., PlanetScope (3 m resolution) …

Quantifying Surface Severity Of The 2014 And 2015 Fires In The Great Slave Lake Area Of Canada, Nancy H. F. French, Jeremy Graham, Ellen Whitman, Laura Bourgeau-Chavez

Michigan Tech Publications, Part 1

The focus of this paper was the development of surface organic layer severity maps for the 2014 and 2015 fires in the Great Slave Lake area of the Northwest Territories and Alberta, Canada, using multiple linear regression models generated from pairing field data with Landsat 8 data. Field severity data were collected at 90 sites across the region, together with other site metrics, in order to develop a mapping approach for surface severity, an important metric for assessing carbon loss from fire. The approach utilised a combination of remote sensing indices to build a predictive model of severity that was …

Rainfall Interception And Redistribution By A Common North American Understory And Pasture Forb, Eupatorium Capillifolium (Lam. Dogfennel), D. Alex Gordon, Miriam Coenders-Gerrits, Brent A. Sellers, S. M. Moein Sadeghi, John T. Van Stan Ii

Earth, Environment & Sustainability: Faculty Publications

In vegetated landscapes, rain must pass through plant canopies and litter to enter soils. As a result, some rainwater is returned to the atmosphere (i.e., interception, I) and the remainder is partitioned into a canopy (and gap) drip flux (i.e., throughfall) or drained down the stem (i.e., stemflow). Current theoretical and numerical modeling frameworks for this process are almost exclusively based on data from woody overstory plants. However, herbaceous plants often populate the understory and are the primary cover for important ecosystems (e.g., grasslands and croplands). This study investigates how overstory throughfall (P_T,o) is partitioned into …

Unfamiliar Territory: Emerging Themes For Ecological Drought Research And Management, Shelley D. Crausbay, Julio Betancourt, John Bradford, Jennifer Cartwright, William C. Dennison, Jason Dunham, Carolyn A.F. Enquist, Abby G. Frazier, Kimberly R. Hall, Jeremy S. Littell, Charles H. Luce, Richard Palmer, Aaron R. Ramirez, Imtiaz Rangwala, Laura Thompson, Brianne M. Walsh, Shawn Carter

Geography

Novel forms of drought are emerging globally, due to climate change, shifting teleconnection patterns, expanding human water use, and a history of human influence on the environment that increases the probability of transformational ecological impacts. These costly ecological impacts cascade to human communities, and understanding this changing drought landscape is one of today's grand challenges. By using a modified horizon-scanning approach that integrated scientists, managers, and decision-makers, we identified the emerging issues in ecological drought that represent key challenges to timely and effective responses. Here we review the themes that most urgently need attention, including novel drought conditions, the potential …

Data Detectives

In The Loop

A 2020 collaboration between DePaul and the Chicago Department of Public Health (CDPH) filled in missing racial data in the city’s COVID-19 case surveillance system to facilitate a more informed, racially equitable response. Using the algorithm an application was designed that lets CDPH researchers quickly receive calculated racial information when they enter surnames and zip codes. The application design team hopes to build other factors into the app, such as occupation, to improve its COVID-19 predictive modeling.

Spatiotemporal Variations Of City-Level Carbon Emissions In China During 2000–2017 Using Nighttime Light Data, Yu Sun, Sheng Zheng, Yuzhe Wu, Uwe Schlink, Ramesh P. Singh

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

China is one of the largest carbon emitting countries in the world. Numerous strategies have been considered by the Chinese government to mitigate carbon emissions in recent years. Accurate and timely estimation of spatiotemporal variations of city-level carbon emissions is of vital importance for planning of low-carbon strategies. For an assessment of the spatiotemporal variations of city-level carbon emissions in China during the periods 2000–2017, we used nighttime light data as a proxy from two sources: Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) data and the Suomi National Polar-orbiting Partnership satellite’s Visible Infrared Imaging Radiometer Suite (NPP-VIIRS). The results …

"Anishinaabe Time": Temporalities And Impact Assessment In Pipeline Reviews, Sakihitowin Awasis

Geography & Environment Publications

Indigenous ways of living that embrace multiple temporalities have been largely supplanted by a single, linear colonial temporality. Drawing on theoretical insights from Indigenous geographies and political ecology, this article considers how pipeline reviews come into being through contested temporalities and how dominant modes of time dispossess Indigenous peoples of self-determination in energy decision-making. In particular, Anishinaabe clan governance – a form of kinship that provides both social identity and function based on relations to animal nations – is undermined in colonial decision-making processes. Through analysis of documents from Canada’s National Energy Board and interviews with Anishinaabe pipeline opponents, I …

The Quest For Greener Pastures: Evaluating The Livelihoods Impacts Of Providing Vegetation Condition Maps To Pastoralists In Eastern Africa, Elia Machado, Helene Purcell, Andrew M. Simons, Stephanie Swinehart

Publications and Research

The survival of millions of pastoral households in Eastern Africa has become increasingly at risk. Due to mounting socioeconomic and climatic stressors, pastoral households are faced with making migration decisions under increasing uncertainty about resource availability and limited coping strategies. We assess the potential of providing vegetation condition maps to support the migration decision of pastoralists in Ethiopia and Tanzania and the effect of map usage on their herd condition and size. The maps were generated from remotely sensed data using the Normalized Difference Vegetation Index (NDVI) as a proxy for vegetation condition and overlain with pastoralists’ preferred grazing areas. …

Agate Fossil Beds National Monument, Paleontological Resources Management Plan (Public Version), Scott Kottkamp, Vincent L. Santucci, Justin S. Tweet, Jessica De Smet, Ellen Stark

United States National Park Service: Publications

Executive Summary

Since Agate Springs Ranch was founded by James H. Cook in 1887, exquisite examples of transitional Miocene mammalian fauna have been found along this stretch of the Niobrara River valley. Collectively these paleontological discoveries, along with the existing archeological and historical Native American collection, were the basis for establishing Agate Fossil Beds National Monument (AGFO) as a unit of the National Park System (NPS). The fossil remains from the Harrison and Anderson Ranch formations span a short, but important, time period within the Miocene Epoch. AGFO has provided science with an intimate look into North American mammalian evolution …

High-Severity And Short-Interval Wildfires Limit Forest Recovery In The Central Cascade Range, Sebastian Upton Busby, Kevan B. Moffett, Andres Holz

Geography Faculty Publications and Presentations

Increasing forest fuel aridity with climate change may be expanding mid-to-high-elevation forests’ vulnerability to large, severe, and frequent wildfire. Long-lasting changes in forests’ structure and composition may occur if dominant tree species are poorly adapted to shifting wildfire patterns. We hypothesized that altered fire activity may lower existing forest resilience and disrupt the recovery of upper-montane and subalpine conifer forest types. We empirically tested this hypothesis by quantifying post-fire forest structure and conifer tree regeneration after spatially large, severe, and rapidly repeated wildfires (
