No. 15: The Food Security Implications Of Gendered Access To Education And Employment In Maputo, Cameron Mccordic, Liam Riley, Inês Raimundo

Hungry Cities Partnership

The multiple linkages between gender and household food security in cities have been observed in diverse settings, at multiple scales, and through a variety of disciplinary lenses. The Hungry Cities Partnership is rooted in the importance of inclusive growth of cities, which includes a fundamental concern with genderbased injustices that reduce inclusivity, sustainability and food security by underpinning structural poverty. This discussion paper is motivated by the gap in policy-ready quantitative data needed to identify the ways in which gender inequality, food insecurity, and public policy are interconnected. Analysis of the 2014 survey of household food security in Maputo identified …

Data: Pre-Fire Disturbance History Modulates Relationships Between Ground Cover And Post-Fire Conifer Regeneration, Nathan Gill, Dan Jarvis, Tom Veblen, John Rogan, Dominik Kulakowski

Student Works

Understory vegetation and ground cover drive many important ecosystem processes, including tree seedling regeneration. The exact effect of ground cover on tree seedling establishment, survival, and growth depends on biophysical context. In subalpine forests, this context is largely determined by disturbances such as beetle outbreak, blowdown, and fire. Compounded disturbances that overlap in short succession can alter stand properties and trajectories in ways that are not predictable from the additive impact of individual disturbances. The aim of this study is to examine how compounded Dendroctonus rufipennis (spruce beetle; SB) outbreak followed by fire and compounded wind blowdown followed by fire …

From Icon Of Empire To National Emblem: New Evidence For The Fallow Deer Of Barbuda, Sophia Perdikaris, Allison Bain, Sandrine Grouard, Karis Baker, Edith Gonzalez, A. Rus Hoelzel, Holly Miller, Reaksha Persaud, Naomi Sykes

School of Global Integrative Studies: Faculty Publications

Barbuda and Antigua’s national animal is the fallow deer, Dama dama dama, a species native to the eastern Mediterranean that has been transported around the world by people during the last 8000 years. The timing and circumstances by which fallow deer came to be established on Barbuda are currently uncertain but, by examining documentary, osteological and genetic evidence, this paper will consider the validity of existing theories. It will review the dynamics of human–Dama relationships from the 1500s AD to the present day and consider how the meaning attached to this species has changed through time: from a …

Accuracy Of Unmanned Aerial System (Drone) Height Measurements, Daniel Unger, I-Kuai Hung, David Kulhavy, Yanli Zhang, Kai Busch-Peterson

Faculty Publications

Vertical height estimates of earth surface features using an Unmanned Aerial System (UAS) are important in natural resource management quantitative assessments. An important research question concerns both the accuracy and precision of vertical height estimates acquired with a UAS and to determine if it is necessary to land a UAS between individual height measurements or if GPS derived height versus barometric pressure derived height while using a DJI Phantom 3 would affect height accuracy and precision. To examine this question, height along a telescopic height pole on the campus of Stephen F. Austin State University (SFASU) were estimated at 2, …

Integrating Unmanned Aircraft Systems To Measure Linear And Areal Features Into Undergraduate Forestry Education, Reid Viegut, David Kulhavy, Daniel Unger, I-Kuai Hung, Brian Humphreys

Faculty Publications

The use of Unmanned Aircraft Systems (UAS) in undergraduate forestry education continues to expand and develop. Accuracy of data collection is an important aspect of preparation for "society-ready" foresters to meet the complex sustainable environment managing for ecological, social and economic interests. Hands-on use of a DJI Phantom 4 Pro UAS by undergraduates to measure the length and area of 30 linear features and areal features on Earth's surface were estimated. These measurements were compared (measured within the ArcMap 10.5.2 interface) to hyperspectral Pictometry imagery measured on the web-based interface and the Google Earth Pro interface. Each remotely estimated measurement …

Austin State University (SFASU) campus was performed within a senior level spatial science course in order to create a method for mitigation of desire paths and for campus beautification. Each desire path on campus was identified with the length of each path measured in the field and categorized by the condition of the path in order to assess and determine a necessary solution for each path identified. In addition, Pictometry^® high spatial resolution digital imagery was used to determine …

Public Places And Empty Spaces: Dislocation, Urban Renewal And The Death Of A French Plaza, Roza Tchoukaleyska

Geography & Environment Publications

This article examines the dislocations produced when competing understandings of public space come into contact. Focusing on Montpellier, France, where an urban renewal program has seen portions of the city-centre renovated, the article considers the breaking apart of a North African commercial cluster under the guide of French heritage protection. Arguing that such action is tiedto municipal urban politics and wider trajectories that place diverse identities in a separate category, I trace the process through which a plaza encompassed in the urban renewal program has been labelled as “empty” and “dead” space. Suggesting that the relocation of a well-used outdoor …

Flume Tests On Fluvial Erosion Mechanisms In Tillbed Channels, L Pike, Peter Ashmore, S Gaskin

Geography & Environment Publications

Semi-alluvial stream channels eroded into till and other glacial sediments are common in areas of extensive glacial deposition such as the Great Lakes region and northern interior plains of North America. The mechanics of erosion and erosional weakness of till results in the dominance of fluvial scour and mass erosion due to spontaneous fracture at planes of weakness under shearing flow. There have been few controlled tests looking at erosional mechanisms and resistance of till in river channels.We subjected small blocks of till to unidirectional flows in a laboratory flume to measure the threshold shear stress for erosion and observed …

Landscape Transformation During Ceramic Age And Colonial Occupations Of Barbuda, West Indies, Allison Bain, Anne-Marie Faucher, Lisa M. Kennedy, Allison R. Leblanc, Michael J. Burn, Rebecca Boger, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This research documented the history of landscape transformation on the island of Barbuda in the Lesser Antilles, Caribbean through cross-disciplinary research approaches. Excavations confirmed a human presence for the seasonal exploitation of conch meat and other mollusks during the Archaic Age (c.3000–500 BC), but more substantial impacts to terrestrial ecosystems likely began during the Ceramic Age (c.500 BC–AD 1500). Our combined sedimentary and charcoal records revealed that human-induced environmental transformations began with Ceramic Age peoples as they cleared vegetation for settlements and gardens with intentional burning. Sedimentary charcoal indicated a dramatic decline in fire during post-Ceramic Age abandonment, continuing through …

No. 22: Predictors Of Household Food Insecurity In Maputo And Matola, Mozambique, Cameron Mccordic, Ezequiel Abrahamo

Hungry Cities Partnership

The rapid growth of Maputo and Matola (neighbouring cities in Southern Mozambique) has dramatically changed each city’s demographic and food insecurity profile. Previous research in Maputo indicates that household access to infrastructure plays an important role in determining vulnerability to food insecurity. This paper investigates (a) whether this relationship is also true of Matola and (b) whether the demographic composition of households plays a role in defining vulnerability to food insecurity in either city. Using household survey data collected by HCP in 2014 in Maputo and Matola, the paper demonstrates that inconsistent access to water, electricity, medical care, cooking fuel …

No. 13: The Growth Of Food Banking In Cities Of The Global South, Daniel N. Warshawsky

Hungry Cities Partnership

As the number and size of food banks increase globally, it is critical to research how food banks fit into existing food systems and their role in reducing food insecurity and food waste. After examining the political ecology of urban food waste in food systems, this discussion paper examines the globalization of food banking and its growth in the Global South. Through a case study of FoodForward SA, it critically analyzes the roles that urban food banks play in cities of the Global South. Since many countries in the South have both the highest levels of food insecurity and the …

As the first city-wide survey of household food security in Nairobi, this report provides researchers and policy-makers with detailed data and information about the overall food security picture, as well as important insights into the operation of the city’s food system. In particular, the report demonstrates the vital importance of Nairobi’s food markets …

No. 08: The Urban Food System Of Windhoek, Namibia, Ndeyapo Nickanor, Lawrence Kazembe, Jonathan Crush, Jeremy Wagner

Hungry Cities Partnership

The surprisingly high rate of supermarket patronage in low-income areas of Windhoek, Namibia’s capital and largest city, is at odds with conventional wisdom that supermarkets in African cities are primarily patronized by middle and high-income residents and therefore target their neighbourhoods. What is happening in Namibia and other Southern African countries that make supermarkets so much more accessible to the urban poor? What are they buying at supermarkets and how frequently do they shop there? Further, what is the impact of supermarket expansion on informal food vendors? This report, which presents the findings of the South African Supermarkets in Growing …

Risk Perception In Small Island Developing States: A Case Study In The Commonwealth Of Dominica, Hannah Eboh

Graduate Research Theses & Dissertations

Small Island Developing States (SIDS) face high vulnerability to natural hazards. Understanding risk perception in SIDS is an essential step towards reducing vulnerability on these at-risk island states. A case study in the Eastern Caribbean's Commonwealth of Dominica, which has a notable volcanic risk, is used to explore risk perception. Specifically, focus groups were conducted in 18 villages throughout Dominica where participants produced hand-colored maps to show where they believed volcanic risk existed on the island and shared their reasoning behind their maps.

Surveys were administered to all focus group participants to collect necessary socio-demographic information. Subsequently, participant’s hand-drawn maps …

A Directory Of Cartographic Inventors: Clever People Who Were Awarded A Us Patent For A Map-Related Device Or Method, Mark Monmonier, Adrienne Lee Atterberry, Kalya Fermin, Gabreille E. Marlzolf, Madeleine Hamlin

Geography and the Environment - All Scholarship

As its title and subtitle imply, this book is a collection of short biographies of people awarded United States patents for inventions intended to improve map use or map making. We say “intended” because, as with most patented innovations, their clever ideas seldom made it to store shelves, magazine ads, or mail order catalogs—a fate shared with most improvements proposed in cartography’s scientific-technical journals.

This collection is a spinoff of a project focused on inventions rather than inventors. The project’s principal product was Monmonier's book Patents and Cartographic Inventions: A New Perspective for Map History, published in 2017 by …

A Method For Determining Damage Within Historic Cemeteries: A First Step For Digital Heritage, Justin E. Malcolm

Honors Undergraduate Theses

While it is true that historic cemeteries are places that contain a wealth of knowledge about the history of a community they are sometimes not well maintained. The information within can be lost as grave-markers are damaged either by natural causes or human interaction. In larger cemeteries preserving these significant places can sometimes be difficult due to a number of different factors. Therefore focusing preservation efforts on specific locations where damage is more likely to occur is crucial to ensure that the monuments that are the most at risk are preserved. One possible way of accomplishing this is through the …

From Bison To Cattle: The Ecology Of The Southern Plains 1500-1750, Jenni Tifft-Ochoa

Calvert Undergraduate Research Awards

Bison made their home on the Southern Plains for millennia. However, their migratory patterns began to shift in the 17^th and 18^th centuries. My research investigated what caused this drastic shift and how it had far reaching effects on the ecology of the Southern Plains. Using archives from two prominent Catholic priests, I began to piece together why the bison left the Southern Plains. Rather than focus on the Europeans as the main players, I instead focused on the Indigenous peoples, the animals, and the land as the centralized actors in this project. I discovered that the introduction …

Using Virtual Reality And Photogrammetry To Enrich 3d Object Identity, Cole Juckette, Heather Richards-Rissetto, Hector Eluid Guerra Aldana, Norman Martinez

Department of Anthropology: Faculty Publications

The creation of digital 3D models for cultural heritage is commonplace. With the advent of efficient and cost effective technologies archaeologists are making a plethora of digital assets. This paper evaluates the identity of 3D digital assets and explores how to enhance or expand that identity by integrating photogrammetric models into VR. We propose that when a digital object acquires spatial context from its virtual surroundings, it gains an identity in relation to that virtual space, the same way that embedding the object with metadata gives it a specific identity through its relationship to other information. We explore this concept …

Modeling Pre-Settlement Wetlands In Northern Minnesota, Johnathon T. Salfer

All Graduate Theses, Dissertations, and Other Capstone Projects

Modern land use has dramatically altered the native landscape across much of Minnesota and the United States. “Manifest Destiny” has ingrained the idea in American society that wetlands and related lands of “low value” need to be tamed and made profitable. In many places, wetlands have been drained and removed so that agriculture can take over. In recent years, people have begun to see the unintended consequences of this method, and importance is now being given to natural wetlands through various government projects and programs. Using National Wetlands Inventory (NWI) data, Drainage Index (DI) values calculated from Soil Survey Geographic …
