News From The Chapters 1997-1998, C. Nicholas Raphael

The Geographical Bulletin

The 1997-98 school year saw an increase in volunteering for GTU members. A new initiation criterion for members is to donate five hours for the semester at any of the many off campus sites that needed help. This is an activity sponsored through the Campus Volunteer Center and is a good way to offer community service. We hosted two successful canoe trips this year: the fall trip was on our own Evergreen Lake and the spring trip was on the Vermillion River. Our members, along with the Anthropology Club, continued to keep our ISU Nature Trail clean with regularly scheduled …

Latino Migration To Green Bay, Wisconsin In The 1990s, Marcelo Cruz

The Geographical Bulletin

This paper explores Latino urban migration to Green Bay, Wisconsin, an intermediate size city of approximately 100,000 people. According to the census of 1990 there were approximately 1,500 Latinos living in Brown County with 1,000 ofthese living in the city of Green Bay. By 1997, estimates of the Latino population in Green Bay are from 6,000 to 7,000. Such a growth rate makes Latinos the fastest growing minority group in the city. The paper explores the nature of the migration process within the spatial and temporal context of Latino presence in the major urban centers of Wisconsin, and analyzes settlement …

The Geography Of Kuwaiti Oil Transportation 1970-1980, Waleed Ai-Menais

The Geographical Bulletin

The transportation of oil from Kuwait between the years 1970- 80, which was a period of relative political stability, is discussed. Based on physical, geopolitical and economic factors the country elected to use tankers rather than pipelines as did many other Gulf countries. During the period 1970- 80 the oil field to transport facilities, onshore and offshore rapidly expanded and technologically improved. Paralleling this active growth, oil tanker construction and capacity had increased. In recent years geopolitical circumstances in Kuwait and emerging Asian markets justify the option of tankers moving oil via the Gulf over pipeline transport to Mediterranean ports.

Wealth Generation In Metropolitan America: F.I.R.E. As Savior?, Darryl T. Cohen, Keith G. Debbage

The Geographical Bulletin

The current restructuring of the American economy from goods producing industry to service providing industry has been a focus of concern for many social scientists. While some argue in favor of the rapidly expanding service sector, pointing out that growth in services creates employment and generates income, others emphasize that many service sector jobs pay considerably less than comparable manufacturing sector jobs, which continue to be lost in many metropolitan areas. The Finance, Insurance and Real Estate (F.I.R.E.) industry in particular, is a branch of the service sector that is often associated with the generation of affluence and productivity. This …

The Relevance Of Gamma Theta Upsilon To Geography In The 1990s, James A. Tyner, Daniel Donaldson

The Geographical Bulletin

The status of geography has long been a concern to its practitioners. Efforts have been proposed to increase both the visibility and vitality of geography at all educational levels. These efforts include the activities of social organizations such as Gamma Theta Upsilon (GTU). This paper tests the hypothesis that geography departments with active chapters of Gamma Theta Upsilon, a geography honor society, will experience a greater increase in declared geography majors than will departments with inactive GTU chapters. Findings confirm our hypothesis, and suggest that Gamma Theta Upsilon, as a visible and active honor society on university campuses, does contribute …

Projections And Perceptions Editorial Comment: Has Land Use Development Lost Touch With The American Landscape? The Need For Geographers In Planning, William M. Marsh

The Geographical Bulletin

There is a predictable sameness creeping over the fact of the North American landscape. In the past several decades, highways, shopping centers, residential subdivisions and most other forms of development have taken on a remarkable similarity from coast to coast. Not only do they look alike, but modern developments also tend to function alike, including the way they relate to the environment; that is, in the way land is cleared and graded, streets are laid out, stormwater is drained, buildings are sited and designed, and landscaping is arranged. We know that this fa~ade of development masks an inherently diverse landscape …

Global Estimates Of The Storage And Transit Time Of Water Through Vegetation, Andrew Felton, Joshua B. Fisher, Koen Hufkens, Adam J. Purdy, Seth A. Spawn-Lee, Lou F. Duloisy, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The time it takes for water to transit from the ground back to the atmosphere affects weather, climate, biogeochemistry and ecosystem function. The transit time of water through vegetation, defined as the age of water transpiring from vegetation since time of entry, is a particularly understudied aspect of the terrestrial hydrologic cycle. Here we use a synergy of satellite remote sensing measurements over a five-year period to estimate global aboveground vegetation water storage to be on average 484 km³, roughly half of which is stored in Earth’s water-limited savannah, grassland and shrubland ecosystems. We then combine these storage …

From Land Reform To Landfare: Land Claims And The Welfare State In Kerala, India, Sudheesh R.C

Articles

While large-scale land reform may still be underway in many countries, other contexts have states responding to land claims through scattered land provision measures. This article puts forward “landfare” as a lens to capture such measures and unpacks its features in one location. The article first explains this term, outlining its location in and departure from the land reform scholarship. It next shows how Kerala, India, widely cited in the scholarship for its 20th century land reform, addresses the land claims of its Adivasi citizens in the 21st century through landfare. Through an exploration of Adivasi land claims and an …

From Climate To Conflict: Unravelling Multidimensional Vulnerabilities Of Small-Scale Fisheries In The Jaffna Peninsula Of Sri Lanka, Mahinda Senevi Gunaratne, R. B. Radin Firdaus, Augustine Sosai Sihivaitthasan, Sarjiyanto Sarjiyanto, Mohd Hafiidz Jaafar

The Qualitative Report

Vulnerability studies have often centered on climate change and catastrophic climatic events. Contrary to this trend, this study explores the multidimensional vulnerabilities faced by small-scale fisheries (SSFs) in the Jaffna peninsula of Sri Lanka. We employed the Integrated Vulnerability Analysis for Sustainability (IVAS) Framework for this analysis. Data was collected through focus group discussions and key informant interviews using semi-structured questionnaires. We analyzed our data following Reflexive Thematic Analysis using ATLAS.ti software and identified 15 vulnerability drivers across five domains specific to the local context, revealing that SSFs in the Jaffna peninsula are highly susceptible to multiple vulnerabilities.

Using Spatial Network Analysis To Explore Migration Of Extended Families In Historical Research, Rock Miller

Theses and Dissertations

This project proposes a geoinformatics approach for understanding the migration of extended families in historical contexts. It uses full-count longitudinal census data (developed by the Minnesota Population Center) and graph methods to define multi-generational extended family relationships and to model the locational structures of these families as a spatial network. Graph algorithms and mapping methods are used to interrogate these structures as reflections of the patterns of family outmigration and extension over time. The study is based on a set of extended families resident in a 15-county study area in the Bluegrass region of Kentucky in 1870, and their evolution …

Forest Above-Ground Biomass Estimation Using Nasa Gedi Lidar Waveforms And Global Tree Allometry, Ian Grant

Theses and Dissertations

Above-ground forest biomass plays a crucial role in global carbon cycles, yet accurately estimating biomass at global scales remains challenging. This thesis addresses two key challenges in processing NASA’s Global Ecosystem Dynamics Investigation (GEDI) space-borne lidar data to estimate above-ground biomass density (AGBD): accounting for global variation in forest structure and developing robust physical interpretations of lidar returns. The first component of the thesis analyzes global patterns of tree allometry using the Tallo tree allometry dataset, examining relationships between tree dimensions across biomes, continents, and plant functional types. This analysis reveals consistent allometry across continents for some biomes (e.g., tropical …

Devising Optimized Maize Nitrogen Stress Indices In Complex Field Conditions From Uav Hyperspectral Imagery, Jiating Li, Yufeng Ge, Laila A. Puntel, Derek M. Heeren, Geng Bai, Guillermo R. Balboa, John A. Gamon, Timothy J. Arkebauer, Yeyin Shi

School of Natural Resources: Faculty Publications

Nitrogen Sufficiency Index (NSI) is an important nitrogen (N) stress indicator for precision N management. It is usually calculated using variables such as leaf chlorophyll meter readings (SPAD) and vegetation indices (VIs). However, no consensus has been reached on the most preferred variable. Additionally, conventional NSI (NSI_uni) calculation assumes N being the sole yield-limiting factor, neglecting other factors such as soil water variability. To tackle these issues, this study compared various variables for NSI calculation and evaluated two new N stress indicators in minimizing the impact of confounding water treatment. The following ground- and aerial-derived variables were compared …

Coffee Farmgate Price And Post-Harvest Processing In Honduras., Isaac Desouza

Theses and Dissertations--Agricultural Economics

Volatile commodity markets and changing climate expose coffee farmers to price and production risk. Proponents recommend specialty coffee as a strategy to combat price risk, because its unique attributes differentiate it from commodity coffee. Extrinsic and intrinsic attributes define specialty coffee and affect prices at many levels of the supply chain. Despite much work on extrinsic attributes, little is known about how intrinsic attributes relate to farmgate price. Post-harvest processing is itself an intrinsic trait and driver of coffee quality. In 2024 we surveyed 261 coffee farmers from La Paz, Honduras, to uncover relationships between capital, post-harvest processing, and farmgate …

Changes In Small Area Flow Accumulation And Watershed Creation In Fredericksburg, Virginia, Jacob P. Lohr

Research and Creativity Symposium

This study explores the application of watershed analysis tools—including the Flow Accumulation, Flow Direction, and Fill tools—on small-scale areas within the rapidly developing City of Fredericksburg. By applying these GIS tools to high-resolution LiDAR-derived Digital Elevation Models (DEMs), the study examines water flow patterns before and after urban development. Results from two primary study sites demonstrate that, when properly utilized, these tools can effectively delineate small-scale hydrological changes from urban development. However, analysis of a third site reveals challenges associated with DEM cleaning. Particularly, the limitations of the Fill tool, highlighting the need for manual editing and further refinement for …

Military Forensic Archaeology: The Process And Recovery Of U.S. Missing-In-Action (Mia) Service Personnel, William Belcher, Luann Wandsnider, Ella N. Axelrod, Finn Kennison, Alicia Lawson

Department of Anthropology: Faculty Publications

The United States (U.S.) Department of Defense's (DoD) Defense POW/MIA Accounting Agency (DPAA) is the largest skeletal identification laboratory in the world and receives several hundred cases per year for identification related to Missing-in- Action (MIA) U.S. service members. While there are various sources for these accessions, by far the largest source is through unilateral or bilateral (done in cooperation with another governmental entity or nongovernmental organization) as well as public-private partnership excavations. While the DPAA-style military forensic archaeology follows archaeological principles and recording standards, the work is goal-oriented, evidence/trace-driven, and time-constrained— a common occurrence with cultural resource management sites …

Subsurface drainage is implemented throughout the Midwest United States to remove excess moisture from soil to enhance crop growth. Hydric soils are ubiquitous throughout Minnesota and are commonly drained due to their historically saturated conditions. Changing a soil's hydrology can impact its formation and properties. The alteration of physical, biological, and chemical soil properties can occur to both hydric and non-hydric soils, impacting overall soil health. The purpose of this study is to examine the short-term effects of tile drainage on the soil health of hydric and non-hydric soils in southern Minnesota. Research methods include: 1) collect soil-sediment cores to …

Spatial Implications Of Potential Treeline Campfire Restrictions In Selected Usfs-Managed Colorado Wildernesses, Rebecca Hippensteel

Masters Projects

High-elevation ecosystems in Colorado’s Wilderness areas are ecologically sensitive and particularly vulnerable to campfire impacts, which can damage vegetation, alter soil chemistry, and degrade wilderness character. This study presents a preliminary proof of concept evaluating the spatial implications of banning campfires at or above 11,000 feet—used here as a proxy for treeline—in twelve U.S. Forest Service-managed Wilderness areas. Using 30-meter resolution Digital Elevation Models from the USGS National Map and Earth Explorer, a raster-based analysis in ArcGIS Pro identified and quantified acreage above 11,000 feet. Across the twelve Wilderness areas, 268,601 acres were found to lie above treeline, representing an …

Unseen Connections: A Storymap Exploring Case Studies In Water-Energy Transitions And Environmental Justice, Alida Cantor, Elizabeth Bartholomew, Kate Berry, James Blair, Dustin Mulvaney, Nancee Hunter

Geography Faculty Publications and Presentations

Climate change is one of the most important challenges in the world today. Communities and decision makers at many levels, from local to international, are working to ensure that energy, water, and other societal infrastructures can transition and adapt to address climate change (IPCC, 2023). One major mitigation strategy involves the decarbonization of energy systems (Rockström et al. 2017). Despite wide recognition of the need to decarbonize globally, renewable energy infrastructures and technologies are often locally controversial, involving claims of environmental injustice and disputes over land and water (Cantor, Turley, and Maxfield 2023; Jerez, Garcés, and Torres 2021; Turley et …
