Using Willingness-To-Pay Surveys When Assessing Dam Removal: A New Hampshire Case Study, Jo Beth Mullens, Veronica Wanstreet

The Geographical Bulletin

As dams in the United States age and become obsolete and river restoration emerges as a new priority, dam removals have increased . Feasibility studies serve to detail the costs and benefits of such proposed dam removals; however, most do not consider intangibles such as the benefits derived from reconnecting seasonal fish habitat or improving the biological diversity within a river . In this research, a willingness-to-pay survey was used to assign a monetary value to intangible goods associated with the proposed removal of an historic dam on the Ashuelot River in southwestern New Hampshire . Within the town where …

Photosystem Stress Of Understory Balsam Fir (Abies Balsamea) In Ontario, Canada As Measured By Chlorophyll Fluorescence, Shannon R. Mccarragher, David Goldblums

The Geographical Bulletin

The goal of this research was to assess the health and physiological stress of understory balsam fir (Abies balsamea) seedlings and saplings within Lake Superior Provincial Park (LSPP) in Ontario, Canada to provide an indication of the degree to which they are affected by ambient light levels . The photochemical efficiency of balsam fir photosystem II was tested by measuring fluorescence . Seedlings and saplings within four sites were sampled and measured for their daily photochemical efficiencies . It was hypothesized that the sampled balsam fir would display little, if any, light stress because balsam fir is relatively shade tolerant …

A New Technique For Predicting The Sky-View Factor For Urban Heat Island Assessment, Richard R. Shaker, Taly Dawn Drezner

The Geographical Bulletin

The urban heat island (UHI) has been documented in large and small urban areas worldwide . Many metrics have been created to model the UHI . Among these, sky-view factor (SVF) has been accepted as a robust survey technique for capturing the urban geometry associated with longwave radiation storage and thus the urban heat island . SVF assessment has improved both in collecting and processing, but has limitations for modeling the UHI, as its accuracy is limited to areas of high urban density and geometry commonly found in the arrangement of human built landscapes . This paper develops a simple, …

Geolinguistics: The Incorporation Of Geographic Information Systems And Science, Shawn Hoch, James J. Hayes

The Geographical Bulletin

Modern geographic information systems (GIS) and its incorporated spatial analysis tools allow sophisticated and efficient analysis of spatial data by researchers in many fields . Although the field of linguistics has long been of interest to geographers and spatial variation of language to linguists, researchers have made little use of the power of GIS and GIScience theory to address hypotheses regarding spatial variation of language and correlated physical and social variables . Discussion of modern GIS tools for spatial analysis, quantitative analysis, and cartography in geolinguistics has been largely absent from the literature . Linguists have applied GIS technology in …

Long-Term Change Around Skytrain Stations In Vancouver, Canada: A Demographic Shift-Share Analysis, Nicole M. Foth

The Geographical Bulletin

This study examines the long-term demographic implications of the SkyTrain, a lightrail rapid transit system, on surrounding neighbourhoods in Vancouver, Canada . Using demographic Census data from 1981 and 2006, shift-share analysis shows the residents’ characteristics change over time . Results demonstrate that SkyTrain neighbourhoods near stations have become physically denser, wealthier and more educated compared to Vancouver as a whole . From these results, the article explores the contextual reasons why denser development occurred around the SkyTrain stations and the effect on residential demographics in the area

Tropical Deforestation In The Ecuadorian Chocó: Logging Practices And Socio-Spatial Relationships, Santiago López, Rodrigo Sierra, Milton Tirado

The Geographical Bulletin

This article examines the implications of forest management on biodiversity at a local level and the relationships between deforestation and its geographic and demographic contexts at a regional level in the Ecuadorian Chocó region . We evaluated the implications of logging practices on biodiversity through the comparison of two 5-ha vegetation quadrats in two areas with and without forest management . Results of the local evaluation showed that the managed forest had higher tree density, larger basal area, and more commercial tree species per hectare than the unmanaged area . Yet, forest gaps were notably large in both research sites …

Predicting Gypsy Moth Population Size In Porcupine Mountains Wilderness State Park Using A Satellite Disturbance Index, Jonathan B. Thayn, Courtney M. Ballard, Emily L. Eichholzer, Michael J. Genard, Jordan A. Hawks, John P. Richard

The Geographical Bulletin

The pattern of gypsy moth defoliation in the Apostle Islands suggests that moths arrived first to the most isolated islands, not those that are nearest the mainland or the most visited by tourists. Gypsy moths are primarily wind-dispersed, so at least some of the moths may have been blown across Lake Superior. The Porcupine Mountains, about 55 km away, are a potential source for these moths. We used a satellite image-based disturbance index to map the extent of defoliation in and around Porcupine Mountains Wilderness State Park. Using these data and moth trap data provided by the Slow the Spread …

Analyzing Tornadic Frequency And Regional Climate Change Relationships In Kansas, 1950-2016, Michael S. Molloy, Bimal K. Paul

The Geographical Bulletin

Due to climate change, severe thunderstorms with the potential to produce tornados are expected to be less frequent and more intense over the next several decades. The goal of this research is to determine whether regional climate change is occurring and inf luencing the frequency of tornadic activity occurring in Kansas. Using decadal averages of temperature and precipitation along with decadal tornado totals, we conducted multiple regression analyses to determine if there is a relationship between tornados, precipitation, and temperature from CE 1950 to 2016. We found that four out of seven decades were above the 30-year average of 12.1 …

Relationship Of Flood Peaks To 24-Hour Rainfall In The Eastern Texas Hill Country, South-Central Texas, Richard A. Earl, Jeanett Bosarge, Heather Wooten, Sarita Hedgepeth, Joel Sherrouse

The Geographical Bulletin

The eastern Texas Hill Country is noted for its extreme storm rainfall amounts and the resulting flood discharges. The resulting flash f loods contribute to Texas leading the U.S. in automobile-related, flood fatalities. These f loods produce considerable groundwater recharge to the Edwards Aquifer. A better knowledge of relations between precipitation and peak flood discharges can improve f lood hazard warning and provide estimates of groundwater recharge from ungauged ephemeral streams. The purpose of this study was to analyze the relationship between 24-hour precipitation amounts and peak discharge for four ephemeral streams, with drainage areas between 0.3 to 18.8 mi.2 …

Heat Reduction Capabilities Of Urban Tree Species, Renee Baker

The Geographical Bulletin

Cities are predicted to house 61% of the world’s population within the next 30 years and their ecological footprints extend much farther than the extent of developed land. In addition, they trap 15-30% more radiation than their rural counterparts, making air temperatures 0.6 - 1.3° C warmer. Higher temperatures drive chemical reactions and increases the energy expended in buildings for cooling. In this study, the thermal effects of tree species in Santa Barbara, California were observed using data from the Airborne Visible Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) satellite on June 3, 2014, and MASTER data from June 4, 2014. A …

Enhancing Community Flood Resilience By Incorporating Landscape Hydrological Sensitivity And Connectivity, Wenlong Feng

Dissertations

Rapid urban expansion and dramatic climate change have significantly increased the intensity and frequency of floods worldwide. With rising flood risks, conventional flood defense strategies that rely on structural measures become ineffective. The present designations for flood-prone areas, such as FEMA's flood maps, are becoming unreliable. Flood risk management is shifting toward enhancing community flood resilience, highlighting the importance of non-structural approaches. Landscape resilience has become a foundation of community flood resilience. However, past urban development typically undermined natural hydro-ecological functions and landscape resilience because of poor recognition of landscapes' ecological role, hydrological sensitivity, and hydrological connections. This study aims …

No. 01: South Africa At War: Food Insecurity, Migrant Exclusion And Covid-19 Policies, Jonathan Crush, Sean Sithole

Migration and Food Security (MiFOOD) Network

The policy audit critically examines the South African government’s response to the COVID-19 pandemic, particularly focusing on the militaristic enforcement of lockdowns and the resulting food insecurity and exclusion of migrant populations. The report aims to inform policy-makers about the impacts of these policies and provide recommendations for crisis management.

On 27 March 2020, South Africa imposed a nationwide lockdown to combat the spread of COVID-19. This lockdown, enforced by the police and the military, was characterized by stringent measures including curfews, bans on inter-provincial travel, and the closure of non-essential businesses. These measures, while necessary to control the pandemic, …

Waterhouses : Landscapes, Housing, And The Making Of Modern Lagos, Mark Duerksen

Ohio University Press Open Access Books

Waterhouses is about the places the people of Lagos have inhabited, imagined, and made home for the past two centuries. It asks what a house in Lagos is and explores how the answer to that question has been historically constructed and reconstructed in turn with the city’s changing landscapes. Written for historians of African and Atlantic history, scholars and practitioners of urbanism, and anyone looking to make sense of Africa’s most populous metropolis today, the book is an approachable history of how houses and water have formed modern Lagos.

The book argues that in the coastlands from which Lagos rose, …

Creating Skateboarding Spaces Or Corralling Skaters? The Rise Of Public Skateparks In Rural Northeast Alabama, Stephen G. Tsikalas, Mark Allen Jones, Jr.

The Geographical Bulletin

The construction of a series of public skateboarding parks (skateparks) in rural areas in northeast Alabama came about between 2005 and 2007. Skateparks are expensive projects for rural Alabama city governments to undergo; yet, numerous parks have been built within the last decade. Our research explores why these parks were built, where space was allocated for the park, who funded them, and how the space is regulated. The majority of our data come from interviewing city authorities or parties that had a role in funding or campaigning for a skatepark. We have found the establishment of these parks had mix …

Performance Art And Pedestrian Experience: Creating A Sense Of Place On The Third Street Promenade, Kalli F. Doubleday

The Geographical Bulletin

It is well attested that wherever people gather, acrobats, poets, musicians, dancers, and tricksters also appear and perform. Although street performers can be found throughout the entire world, they are curiously shunned in New York City, while Plovidiv, Bulgaria in March 2015 decided to follow other European cities in having auditions or qualifiers for performers in public places. This research adds to scholarship on performance art as a beneficial element in developing a sense of place in urban environments, particularly pedestrian malls. A hundred surveys were collected from Promenade visitors to highlight these connections in a case study of street …

#Makeamericaspollsgreatagain: Evaluating Twitter As A Tool To Predict Election Outcomes, Jaryd Hinch

The Geographical Bulletin

Traditional political polling methods have become less reliable as society adopts more smartphone technology. Internet and social media use have also risen due to increased smartphone use, which have given a digital voice to political views. This study assessed one social media platform, Twitter, as a means for predicting election outcomes more accurately than traditional methods. Michigan and Wisconsin’s ‘tweets’ related to the 2016 presidential election campaign slogans of candidates Hillary Clinton and Donald Trump were compiled and a numerical comparison was performed. WordCloud technology was employed for a visual representation of the numerical data. Numerical comparison yielded results and …

Paleo Environment And Archaeology Provide Cautionary Tales For Climate Policymakers, Brett Kaufman, Christopher S. Kelly, Richard S. Vachula

The Geographical Bulletin

Federal climate policy in the United States is still in its infancy and is in large part characterized by efforts to reach a consensus on the very existence and causality of climate change. This has stemmed from a sociopolitical rift within the country, with the objectivity and usefulness of science attacked by detractors. Scientists who are most qualified to defend their methods and provide information to policymakers rarely have an institutional incentive to share this knowledge, but should be encouraged to communicate their findings to the public, especially those who receive public funding. By not doing so, they are effectively …
