Adopting Yield-Improving Practices To Meet Maize Demand In Sub-Saharan Africa Without Cropland Expansion, Fernando Aramburu-Merlos, Fatima A. M. Tenorio, Nester Mashingaidze, Alex Sananka, Stephen Aston, Jonathan J. Ojeda, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Maize demand in Sub-Saharan Africa is expected to increase 2.3 times during the next 30 years driven by demographic and dietary changes. Over the past two decades, the area croppedwithmaize has expanded by 17million hectares in the region, with limited yield increase. Following this trend could potentially result in further maize cropland expansion and the need for imports to satisfy domestic demand. Here, we use data collected from 14,773 smallholder fields in the region to identify agronomic practices that can improve farm yield gains. We find that agronomic practices related to cultivar selection, and nutrient, pest, and crop management can …

Responding To The Call: How States Handle Federal Family Engagement Guidelines And The Similarities And Differences Between States, Owen Boxer

Washington Semester Program

Throughout the history of American federal education legislation, policy has almost always been vague and left to state interpretation. This is no different for family engagement, which are two-way interactions between families and schools that build and change the capacities of both partners. Since 2015, federal money has been allocated to the Statewide Family Engagement Centers, including twelve SFECs given initial funding in 2018, to carry out family engagement activities on the state level. Using a mixed method approach, I conducted research to 1. examine how SFECs interpret federal guidelines (specifically those in the Every Student Succeeds Act of 2015), …

Here, we present full depth profiles of dissolved (d) and particulate Al, Mn, and Co along the latitude of 40 °S in the South Atlantic Ocean from the GEOTRACES GA10 cruises that operated in austral spring 2010 and summer 2011. The region is characterized by enhanced primary productivity and forms a key transition zone between the Southern Ocean and South Atlantic Subtropical Gyre. The mean concentrations of dAl, dCo, and dMn (±standard deviation) were 3.36 ± 2.65 nmol kg⁻¹, …

Carbon Stocks And Fluxes From A Boreal Conifer Swamp: Filling A Knowledge Gap For Understanding The Boreal C Cycle, Sj Davidson, Marissa Davies, E Wegener, S Claussen, M Schmidt, M Peacock, M Strack

School of Geography, Earth and Environmental Sciences

The carbon (C) dynamics of boreal coniferous swamps are a largely understudied component of wetland carbon cycling. We investigated the above- and below-ground carbon stocks and growing season carbon dioxide (CO ₂) and methane (CH ₄) fluxes from a representative boreal coniferous swamp in northern Alberta, Canada in 2022. Tree inventories, understory vegetation biomass and peat cores were collected across three sub-sites within the broader swamp, with gas flux collars placed in the dominant plant communities present. Alongside the C flux measurements, environmental variables such as water table depth, soil temperature and growing season understory green leaf phenology …

Conceptualising And Enacting Pathways To Transformative Climate Justice: Examples From The Philippines, Justin See, Anne Shangrila Fuentes, Emma Porio, Brooke Wilmsen

Sociology & Anthropology Department Faculty Publications

Scholarship on climate change adaptation is increasingly moving from incremental responses to climate injustice towards transformative approaches that deliberately change systems to achieve just and equitable outcomes. A transformative understanding of climate justice is relatively new and evidence of how this could be achieved is in its infancy. In this paper, we conceptualise transformative climate justice as comprised of three subcomponents: (1) inclusive justice (seeking to ensure that no one, especially the most vulnerable, is left behind), (2) epistemological justice (drawing upon diverse knowledges and worldviews), and (3) restorative justice (healing and restoration of communities and the environment). We then …

The Atlanta Beltline is an evolving project that has blossomed in Atlanta, and not only serves as a source of recreation but also to connect different surrounding communities. More specifically, the vast amount of artwork along the Atlanta Beltline is a clear representation of how welcoming and supportive of others the communities are. This research recorded every piece of artwork along the Atlanta Beltline on the Eastside segment. A photograph was taken for each piece of artwork along. It was followed by recording various attributes of each piece of artwork, such as date, time, location, direction, and whether the artwork …

Generating Channel Morphology Data Through Arcgis Pro, Ethan Manigbas

Symposium of Student Scholars

River cross-sections are often extracted using field surveys at measured intervals. This field-oriented approach allows for a tangible relationship between the data and its collector but at the expense of finance, time, labor, and potentially the environment. With the advancement of geospatial tools, such data can be found online, extracted, and even analyzed with contemporary Geographic Information Systems (GIS) in a completely virtual setting, transcending the need for fieldwork in select project topics. We tested this approach with the help of ArcGIS Pro software on the Vishnu Springs headwater stream located in the Western Illinois region of the Upper Mississippi …

No. 21: Refugee Migration And Urban Food Security: Somali Migrants In Nairobi, Kenya, Zack Ahmed, Jonathan Crush, Samuel Owuor, Elizabeth Onyango

Migration and Food Security (MiFOOD) Network

This paper investigates the relationship between refugee migration and urban food security, focusing on Somali migrants in Nairobi, Kenya. Despite the abundance of literature on urban refugees and their economic integration, scant research has addressed their food security challenges. Utilizing a household survey conducted in Nairobi’s Eastleigh neighborhood, the paper explores the levels, determinants, and spatial variations of food security among Somali refugees. Findings reveal that while migration to Nairobi generally improves food security compared to conditions in Somalia, substantial disparities exist within the refugee population, with a significant portion still facing severe food insecurity. Factors such as household type, …

Through a mixed-methods approach comprising household surveys in Ghana and in-depth interviews with migrants in Qatar conducted from March to June 2023, the paper explores how remittances influence the food security status of recipient households and the socioeconomic conditions of migrants. The findings suggest that remittances play a critical role in enhancing household food security in Ghana by enabling better access to food and improving dietary diversity. Migrants prioritize sending money for basic needs, …

Taking ‘Third World’ Lives Seriously: Decolonising Global Health Governance To Promote Health Capabilities In The Global South, Uchechukwu Ngwaba

The Transnational Human Rights Review

Behind glib claims of universalism in global health, evidenced by the push for universal health coverage in the Sustainable Development Goals 2030 (SDGs), lies an uncomfortable truth about the unequal, uneven and broken system of the existing framework for global health governance. A situation made more evident by the behaviour of powerful states of the Global North at the height of the Covid-19 pandemic through the hoarding of vaccines, refusal to accommodate waivers to the Trade-Related Aspects of Intellectual Property Rights (TRIPS) regime to allow cheaper versions of the Covid-19 vaccines to be manufactured for the Global South and the …

The Sect. Tricheroides In The Genus Knautia (Caprifoliaceae) Is More Complex Then Known: An Unusual New Species From Türkiye, Candan Aykurt, Mertcan Gülben, Sinem Günaydin, Duygu Sari, Ramazan Süleyman Göktürk, Emirhan Berberoğlu, Serkan Gülsoy

Turkish Journal of Botany

During a biodiversity survey in the Western Taurus Mountains (Antalya, Türkiye), a new species of the genus Knautia (Dipsacoideae, Caprifoliaceae), K. sivridaghense, was discovered. The new species, which is characterized by its dwarf caespitose perennial habit, is found in rocky places under mixed forests at elevations of 1400–1450 m. Knautia sivridaghense is distinguished from its morphologically similar species, K. goecmenii, especially by its dwarf caespitose perennial habit, unbranched stems, length of involucral bracts, and other floral characteristics. Our phylogenetic analyses based on the nuclear ITS and chloroplast petN(ycf6)-psbM regions confirm its placement within Sect. Tricheroides, contributing to the understanding of …

Longitudinal Spatial Trends In U.S. Pedestrian And Bicyclist Fatalities, Ossiris Rodriguez, Nicholas N. Ferenchak

Civil Engineering ETDs

Between 2009 and 2022 in the United States (U.S.), pedestrian fatalities increased 82.3% and bicyclist fatalities increased 70.8%. Several studies have researched crash characteristics such as the people and roadways involved in these crashes. But where are these fatalities occurring within our regions and what spatial characteristics of these locations could be influencing this trend? We analyzed pedestrian and bicyclist fatality data from the last two decades using NHTSA’s Fatality Analysis Reporting System (FARS) in relation to built-environment and socio-economic characteristics (such as street network density, transit access, poverty, and educational attainment) obtained from the U.S. Census and the U.S. …

Assessing The Geometry Of The Main Himalayan Thrust In Central Nepal: A Thermokinematic Approach, S. Ghoshal, N. Mcquarrie, D.M. Robinson, T.A. Ehlers

School of Geography, Earth and Environmental Sciences

Since the 2015 Gorkha earthquake in Nepal, the relationship between the geometry of megathrusts and the control it exerts over the nucleation and propagation of major earthquakes has become an important topic of debate. In this study, we integrate new geologic mapping, a newly interpreted cross section from the Daraundi valley of central Nepal, two published cross sections from the neighboring Marsyangdi and Budhi Gandaki valleys, and a suite of 270 thermochronometric ages to create an integrated and validated three-dimensional kinematic model for the central Nepal Himalaya. We use this model to investigate the assertion that the westward propagation of …

Access To Environmental Justice In Canadian Environmental Impact Assessment, Thomas Gilmour, Jocelyn Stacey

All Faculty Publications

Contemporaneous reforms to Canada and British Columbia’s environmental impact assessment legislation have the potential to advance Access to Environmental Justice. Access to Environmental Justice is the ability of individuals and communities who are disproportionately and negatively impacted by environmental decisions to access legal and regulatory processes and to have their concerns heard and addressed through environmental decision-making and dispute resolution. Access to Environmental Justice connects concepts of environmental justice, public participation, the rule of law, and access to justice to provide a framework for evaluating the implementation of environmental impact assessment laws. We conducted a preliminary analysis of early implementation …

Sentinel Surveillance Of Sars-Cov-2 Rates And Equity Impacts Using Labor And Delivery Patients In Phoenix, Arizona, Caitlyn J. Linehan, Trisalyn Nelson, Celeste V. Bailey, Esma Gel, Dean V. Coonrod, Cheryl K. Roth

Department of Supply Chain Management and Analytics: Faculty Publications

Proactive management of SARS-CoV-2 requires timely and complete population data to track the evolution of the virus and identify at risk populations. However, many cases are asymptomatic and are not easily discovered through traditional testing efforts. Sentinel surveillance can be used to estimate the prevalence of infections for geographical areas but requires identification of sentinels who are representative of the larger population. Our goal is to evaluate applicability of a population of labor and delivery patients for sentinel surveillance system for monitoring the prevalence of SARS-CoV-2 infection. We tested 5307 labor and delivery patients from two hospitals in Phoenix, Arizona, …

Chronic Inequities: Environmental & Structural Racism During Covid-19 And Hurricane Laura Disaster Recovery, Tomeka M. Robinson, Sabrina Singh

Critical Disaster Studies

The COVID-19 pandemic has amplified the realities of systemic health inequities within the United States. While the virus has severely impacted the entire country, people of color bear the brunt of this pandemic, from surges of COVID-19 cases in their communities to spikes in unemployment rates. Simultaneously, citizens are dealing with the impacts of natural disasters such as hurricanes along the Gulf Coast. The common denominator concerning these two stressors is that they can be exacerbated by institutional racism. This can be seen in the case of a small city in Southwest Louisiana, namely, Lake Charles, which has become a …

Book Review: The Shaming State: How The U.S. Treats Citizens In Need, Steve Matthewman

Critical Disaster Studies

Salman’s book centers two different constituencies, in two different locations, in the 2010s, who have been impacted by two different disasters. The first group are Iraqi refugees who have been resettled in Wayne County, Michigan. Trying to start again over half a world away, they are trapped in the transit lounge of life, never able to move on, never able to properly belong. They found a state in recession, the automobile industry collapsing, the city of Detroit bankrupt. Their particular county had higher unemployment than the state’s average and a poor median income as well. Economically speaking, ‘Michigan fared worse …

Preserving Shawnee Identity Through European Trade: How European Trade In Lower Shawneetown Expressed Indigenous Independence, Kelsey Grace Tuggle

Online Theses and Dissertations

The residents of Lower Shawneetown utilized trade to express independence from colonizing European powers. Unconventionally, the Shawnee articulated their freedom from colonization through direct trade be and diplomacy with European governments in the New and Old Worlds. The dynamics of trade in Lower Shawneetown were volatile, reflecting changes in Shawnee conceptualization of independence. European traders did not understand their actions through Shawnee colonial liberation, instead believing Lower Shawneetown trade furthered colonization efforts. Due to this inherent misinterpretation of Shawnee trade practices, European powers frequently engaged in hostilities against each other to court Lower Shawneetown’s favor.

Digital Deception: Geographies Of Crisis Pregnancy Centers Post-Roe, Patricia Simone Yoxall

Theses - ALL

Anti-abortion groups have opened thousands of ‘crisis pregnancy centers’ (CPCs) across the country that deceive pregnant people in order to discourage or outright prevent them from accessing abortion. Amidst tightening state restrictions, those seeking abortion are increasingly looking online for legal guidance, resources, and care itself. Activists and scholars have celebrated the possibility that the Internet might promise enduring access to abortion care through online pill provision. However, the two papers presented here provide evidence that CPCs are also increasingly adopting a new arsenal of digital strategies to identify and reach those they label “the abortion-determined,” interrupting new geographies of …

Burning Calories, Burning Ocean: Metabolic Rate In Bivalves As A Predictor Of Extinction Selectivity Through Time And During Rapid Global Warming, Siddharth Gavirneni

Theses - ALL

Organismal metabolic rate is linked to environmental temperature and oxygen consumption, and as such, may be a useful predictor of extinction risk during major climate- driven crises. However, metabolic attributes can be quantified in many ways, highlighting differing aspects of organisms’ ecology. Here, we estimate resting whole-body and mass-specific metabolic rates in post-Carboniferous bivalve taxa using body size and seawater paleotemperature to assess how metabolic rate determines survival both during and outside of intervals of rapid climate warming, or ‘hyperthermals’. Accounting for the effects of geographic range size, we find a pattern of preferential extinction of bivalves with lower total …
