Realizing Where I Should Be: Notes On Reflexivity And Positionality In Fieldwork, Dylan M. Harris
Realizing Where I Should Be: Notes On Reflexivity And Positionality In Fieldwork, Dylan M. Harris
The Geographical Bulletin
An awareness of positionality, an attention to accountability, and a commitment to reflexivity are increasingly key elements to conducting geographical fieldwork. As such, the ‘field’ is not only a place where we go to conduct research. The ‘field’ is a place where people live, where histories are present, and where our actions are never objective. This short article discusses my experiences as an early career researcher as I came to terms with these realities during preliminary dissertation research in Nepal. As a result of several formative moments – including surviving a landslide – I slowly began to realize that issues …

Fieldwork In Oil And Gas Development Communities: Experiences Of A Research From The Global South, Avantika Ramekar
The Geographical Bulletin
Fieldwork in communities affected by resource extraction is tricky and involves complex interactions between institutional networks, community histories, location of the resource, and researcher positionality (Jenkins et al. 2015). My research assessed risk perceptions regarding oil and gas development using Hydraulic Fracturing and Directional Drilling (HFDD), and factors contributing to levels of perceived risk. I employed an explanatory sequential mixed methods design (Wetherholt 2016) that used a combination of procedures. Mixed method research is a common approach to understanding the perspectives of those living in environments of change. In this case, a mailed questionnaire (focused on gathering quantitative data, with …

Becoming An Ally And Understanding The Geographies Of Gender Identity: Lessons From Fieldwork, Shamayeta Bhattacharya
The Geographical Bulletin
My “field”, Kolkata, India inspired my “work”, i.e., my research work. Before coming to the United States in 2017 for graduate school, I was associated with several queer organizations in Kolkata (also my hometown) and developed friendships and association which was the major motivation for my dissertation “SHAKTHI: Studying Healthcare Accessibility among Kothi, Transgender, and Hijra Individuals.” The word, SHAKTHI, in Sanskrit means “power” or “empowerment”. My dissertation is by and for transgender and gender diverse (TGD) people, with a goal to empower them. It is theoretically grounded in transgender geography, health geography, and geospatial analysis. During my dissertation coursework, …

Our personnel included geographers and government officials from the Soviet Academy of Sciences, Tajik Academy of Sciences, Goscomproda (Tajik Ministry of Environment), and the NGO Tajik Socio-Ecological Union. The initial 1991 field season involved living in Moscow through the coup attempt that ultimately disbanded the Soviet Union. …
Debunking Muslim Stereotypes: Learning Religious Tolerance And Acceptance Through Geographic Fieldwork, Elizabeth Nelson
Debunking Muslim Stereotypes: Learning Religious Tolerance And Acceptance Through Geographic Fieldwork, Elizabeth Nelson
The Geographical Bulletin
According to the SAGE Handbook of Fieldwork, “fieldwork” refers to primary research that occurs “in the field,” the “field” being a setting that is outside the controlled settings of the library or laboratory (McCall 2006, 2). As a human geographer, my fieldwork involves participant-observation within the ethnographic tradition that requires the insertion of me (the researcher) into the subject matter of my work – the lives and experiences of Algerian immigrants and their descendants living in Paris, France. As a Western scholar doing research on a postcolonial population embedded within their former colonizer’s social systems, it is important for me …
Generating Channel Morphology Data Through Arcgis Pro, Ethan Manigbas
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 …

Recovery Of Microtopography Following Prairie Restoration: Implications For Biodiversity Monitoring, Karli Cich, Scott Powell
Recovery Of Microtopography Following Prairie Restoration: Implications For Biodiversity Monitoring, Karli Cich, Scott Powell
The Geographical Bulletin
Tallgrass prairies are often restored from agricultural fields where the natural microtopography has long since been removed. Therefore, our study investigates the degree to which restored prairies recover microtopography. Differences in microtopography were measured using precise elevation data collected from LiDAR to compare differences in microtopography between crop fields, fallow fields, newer restored prairies, and older restored prairies. We also compared plant biodiversity indices between newer and older restored prairies using nested plot vegetation sampling. Our first research question is how microtopography differs between the sites. Our results show that older restored prairies had the most microtopographic variation, followed by …

Modeling The Impact Of Ocean Temperature Increases On The Distribution Of Seagrasses Around The Korean Peninsula Using A Machine Learning Technique, Jina Jang, Seohyeon Kim, Jeong Seong
The Geographical Bulletin
Seagrasses are important resources which form a vital part of the ocean ecosystem. They are also considered blue carbon because of their capability of sequestrating carbon. Seagrass distribution can be affected by many factors including ocean temperature. It is highly likely that recent climate change may increase ocean temperature significantly in East Asia and consequently alter seagrass distribution patterns. This study aims at predicting the impact of ocean temperature increases on seagrass habitats around the Korean Peninsula. Using the Maximum Entropy (MaxEnt) Model, seagrass habitat distributions were modeled when sea temperature rises by 1°C, 2°C, 3°C, and 4°C. Results show …

A Remote Sensing Investigation Of The 2022 Invasion Of Eastern Ukraine On Agricultural Landcover, Michael S. Agbozo, Luke J. Marzen, Chandana Mitra
The Geographical Bulletin
Ukraine-Russian political relations over the years have alternatively experienced periods of tranquility and turmoil with violent conflicts since 1917, including the events of the 2014 annexation of Crimea and the 2022 Russian invasion of the entirety of Ukraine. These conflicts remain developmental threats and their assessment requires multi-perspective analysis. Understanding the spatial dimensions of such conflicts and their consequences on physical and social spaces at varying scales could provide credible scientific impetuses on which targeted post-conflict remediations could be built. This preliminary study therefore takes advantage of the capabilities of satellite remote sensing, to provide quick and effective spatiotemporal analysis …
Open-Source Based Change Pattern Analysis Of Urban Green Spaces Using Landscape Metrics, Mohammad Anwar Alattar
Open-Source Based Change Pattern Analysis Of Urban Green Spaces Using Landscape Metrics, Mohammad Anwar Alattar
The Geographical Bulletin
A growing number of studies have been conducted on urban green spaces (UGSs), given their essential role in mitigating urbanization externalities. The current available methods for acquiring and analyzing UGSs data suffer from several limitations. For example, free satellite imagery exhibits pixel distortion and fails to account for fine-grained structure such as accurate geometry or size. Moreover, official UGSs datasets are typically updated periodically, not continuously. This work provides a Python-derived open-source based analysis for acquiring, modeling and analyzing UGSs change patterns using landscape metrics. To demonstrate the feasibility of the proposed approach, it is applied on the New York …

Evaluating The Use Of Unpiloted Aerial Systems To Detect And Monitor Beech Bark Disease In New England Forests, Isabelle Lopez, Benjamin T. Fraser, Russell G. Congalton
The Geographical Bulletin
The American beech (Fagus grandifolia) plays a key role throughout eastern North American forests. However, beech bark disease (BBD) causes widespread mortality of beech trees. We investigated whether imagery collected using an unpiloted aerial system (UAS) could differentiate beech tree health. Reference data were collected from 140 beech trees in New Hampshire and were visually classified as having “no/trace damage,” “moderate damage,” or “heavy damage.” Multispectral imagery was collected from a UAS, and 44 image features were derived for each beech crown. We used machine learning to identify the importance of each feature in distinguishing between the three health classes …

Gis For Public Health: Exploring Diseases Of Despair In Metro Atlanta, Chanice Brown
Gis For Public Health: Exploring Diseases Of Despair In Metro Atlanta, Chanice Brown
Symposium of Student Scholars
Diseases of despair are a set of behaviors that can cause a significant amount of mortality within a population. These behaviors, which typically include drug abuse, alcoholism, and suicides, have existed for quite some time. However, the idea of “Diseases of Despair” is fairly recent. In 2015, researchers Anna Case and Angus Deaton first coined the concept while studying an increase in mortality and decrease in life expectancy amongst middle-aged, white populations in different rural communities. They theorized that external pressures, like economic insecurity and increased morbidity, were driving these populations to seek out dangerous methods to relieve their stress. …

“Leaves From My Journal”: William T. Beatty’S Civil War Account Of The 2nd Ohio Volunteer Infantry, H. Jason Combs, Tate Combs, Paul R. Burger
The Geographical Bulletin
During his time in service, Beatty kept a journal and meticulously recorded dates and key events, though Beatty was not unique in doing so, as diaries, journals, and letters were essential correspondence during the Civil War (Maness and Combs 2010). However, Beatty, who moved to Gibbon, Nebraska following the war in 1872, later shared his original journal entries which were reprinted in the Buffalo County Beacon (Gibbon, Nebraska’s newspaper). Over the course of thirty-three newspaper articles – running from February 1, 1883 to September 21, 1883 – Beatty provided his personal account in the Buffalo County Beacon and referred to …
Of Revolution Or Postcoloniality? Identity Practices Of Algerian Immigrants And Their Descendants In France, Elizabeth Nelson
Of Revolution Or Postcoloniality? Identity Practices Of Algerian Immigrants And Their Descendants In France, Elizabeth Nelson
The Geographical Bulletin
Using qualitative research techniques, this article demonstrates how colonial memory and postcolonial dynamics permeate the everyday lives and encounters of Algerian-origin people in France and inform the ways they conceive of, and experience, social membership and belonging. This work investigates what it means to be a racialized minority in a postcolonial context and to learn and experience the boundaries of ‘Frenchness’ and ‘Algerianness.’ It is based on the narratives of Algerian immigrants who have migrated to Paris, France and their French-born children. The empirical evidence highlights how Algerian immigrants and their descendants encounter and structure their interactions with French society. …
