High Carbon And Biodiversity Costs From Converting Africa's Wet Savannahs To Cropland, Timothy D. Searchinger, Lyndon Estes, Philip K. Thornton, Tim Beringer, An Notenbaert, Daniel Rubenstein, Ralph Heimlich, Rachel Licker, Mario Herrero

Geography

Do the wet savannahs and shrublands of Africa provide a large reserve of potential croplands to produce food staples or bioenergy with low carbon and biodiversity costs? We find that only small percentages of these lands have meaningful potential to be low-carbon sources of maize (1/42%) or soybeans (9.5-11.5%), meaning that their conversion would release at least one-third less carbon per ton of crop than released on average for the production of those crops on existing croplands. Factoring in land-use change, less than 1% is likely to produce cellulosic ethanol that would meet European standards for greenhouse gas reductions. Biodiversity …

Using Spatiotemporal Methods To Fill Gaps In Energy Usage Interval Data, Kristin K. Graves

Theses and Dissertations

Researchers analyzing spatiotemporal or panel data, which varies both in location and over time, often find that their data has holes or gaps. This thesis explores alternative methods for filling those gaps and also suggests a set of techniques for evaluating those gap-filling methods to determine which works best.

Health Exposure, Socio-Economic Vulnerability, And Infrastructure At Risk To Current And Projected Coastal Flooding In New York City, Lesley Patrick

Dissertations, Theses, and Capstone Projects

This work uses a GIS-based methodology to develop and map a composite physical exposure, social vulnerability, and critical facilities index for New York City populations exposed to the current and predicted 100- and 500- year coastal floods. The objective is to illustrate how sea-level rise may affect future 100- and 500-year coastal floods in New York City, how these changes in future flood scenarios will affect the number and distribution of people at risk and their associated physical and socioeconomic impacts, and how these impacts will vary among neighborhoods.

Sea-level rise throughout the 21st century will result in increased flood …

Carbon Emission Policy In The United States: State Patchwork Vs. National Policy, Samuel T. Frank

Dissertations, Theses, and Capstone Projects

The lack of a national law in the United States to mitigate climate change has prompted many states and cities to take the lead in implementing policies to reduce their carbon emissions and adapt to the threats posed by a warming planet. This project adopts two established systems that classify states by their relative involvement in climate policy (Wheeler 2010; Lutsey et al. 2008) and combines them into a single, six-point ranking scale. States are then cross-tabulated against EPA data showing the amount and trajectory of each state's carbon emissions from the electrical power sector over the period 2005-2010. States …

Super Fun Superfund: Polluted Protection Along The Gowanus Canal, Jessica Ty Miller

Dissertations, Theses, and Capstone Projects

This research reflects on the patterns of uneven development occurring in the Gowanus Canal in Brooklyn, social and physical changes taking place there, and how these elements of the canal relate to the changing purpose of urban waterways. Gowanus has mimicked the development of New York City since the 1600's through several phases: city settlement and development, abandonment, and redevelopment. The redevelopment phase in Gowanus couples environmental clean up with gentrification and displacement. Using an urban political ecology framework, this research attempts to answer the following questions: Why, after many years of pollution, is the area being cleaned up? Will …

And Then There Were Two: Why Is The United States One Of Only Two Countries In The World That Has Not Ratified The Convention On The Rights Of The Child?, Mark Engman

International Human Rights Law Journal

Twenty-five years ago, the United Nations General Assembly (‘U.N. General Assembly’) unanimously adopted the Convention on the Rights of the Child (hereinafter the “CRC”), which became the most widely accepted human rights treaty in history. Today, every nation in the world is a party to the CRC – except for two: Somalia, and the United States. This article will analyze the politics behind America’s failure to ratify this treaty. That may seem a little out of place in a law journal, but in reality the United States’ (‘U.S.’) acceptance or rejection of international law is as much a matter of …

Principled Humanitarian Organizations And The Use Of Force: Is There Space To Speak Out?, Scott Paul, Elizabeth Holland

International Human Rights Law Journal

Humanitarian organizations are fundamentally concerned with addressing the suffering of civilians. The decision by an armed actor to resort to force can result in greater protection or greater harm, and has at least as significant an impact on civilian lives as any decision made during the conduct of hostilities. Yet, humanitarian organizations rarely publicly advocate for or against the use of force. This article explores the perceived and actual limitations that humanitarian principles place on the public advocacy of humanitarian organizations regarding the recourse to force. It begins with a discussion of the relevant legal framework and explication of the …

Transitional Justice In Sri Lanka: Rethinking Post-War Diaspora Advocacy For Accountability, Mytili Bala

International Human Rights Law Journal

Sri Lanka’s 26-year civil war against the Liberation Tigers of Tamil Eelam came to a bloody end in May 2009, amidst allegations of war crimes and crimes against humanity on both sides. Since then, Tamils in the diaspora, long accused of funding the war, have become vocal proponents for war crimes accountability. Some might label certain forms of diaspora advocacy as “lawfare” or “long-distance nationalism.” However, these labels fail to account for the complex memories and identities that shape diaspora advocacy for accountability today. In order for Sri Lanka to move forward from decades of conflict, transitional justice mechanisms to …

No Child Is An Island: The Predicament Of Statelessness For Children In The Caribbean, Catherine A. Tobin

International Human Rights Law Journal

In a region characterized by human mobility, many children in the Caribbean are born in a different country than their parents. In fact, the Caribbean is considered one of the regions with the highest percentage of people migrating. This article will analyze the root causes of statelessness for children in the Caribbean, focusing primarily on the dangerous interplay between ineffective birth registration systems and lack of safeguards for children who would be otherwise stateless. The article will also address recent shifts in migration and nationality policies in countries such as The Bahamas and the Dominican Republic that have exacerbated existing …

A Close Look At The Relationship Between Poverty And Political Violence In Nepal, Lauren C. Griffin

Global Tides

Today, one quarter of Nepal’s population of 27 million lives on a daily income of less than two dollars (Sharma 8). Villages are deprived of an ample water supply, and some areas still lie in ruins from the aftermath of the Maoist insurgency. This paper will seek to understand the role of poverty in the historically and presently unfolding political environment of Nepal. Several factors show direct correlation between poverty and insurgent activity, such as land ownership, level of education and socio-economic standing. Nepal has had a volatile and bloody past in the midst of medieval dynasties, an authoritative monarchy …

Eastern Washington Wildfires: Tracking Land Recovery In The Colockum Tarps Wildfire Area, Michael Balda, Allison Shinn

Symposium Of University Research and Creative Expression (SOURCE)

Eastern Washington State has seen an increase in wildfire activity because of policies of fire suppression and changing climate. The Colockum Tarps wildfire started on July 27, 2013, in Malaga, Washington, due to a water pump malfunction. After ignition, the fire quickly moved south-southwest and burned a total area of 80,408 acres of grasslands and forest. We combined fieldwork and geospatial analysis of aerial photography and satellite imagery to examine vegetative recovery within the fire area. Using ArcGIS and PCI Geomatica, we analyzed 2013 National Agricultural Imaging Program (NAIP) images and a wildfire perimeter shapefile from the Bureau of Land …

Here I Am And Here I’M Not: Queer Women’S Use Of Temporary Urban Spaces In Post-Katrina New Orleans, Vigdís María Hermannsdóttir

LSU New Orleans Theses and Dissertations

This thesis builds on previous work on the relationship between queer identities and urban space. Drawing from an analysis of two recurring New Orleans-based queer women’s events, I examine how lesbians and queer women not only use but also actively produce social spaces of their own through participation in events organized specifically for lesbians and queer women. Using qualitative methods, I examine the ephemeral and transient quality of lesbian and queer women’s social spaces in post-Katrina New Orleans and the processes through which such spaces come into being. I argue that lesbian and queer women’s production of ephemeral social spaces …

Network Analysis Of The Walkability Of Denver’S Light Rail And Bus Rapid Transit Network And How This Can Be Improved, Ryan Ferriman

Geography and the Environment: Graduate Student Capstones

This study evaluates how well the existing and proposed light rail and bus rapid transit lines in Denver serve residents who want to get by without a car. The number of residents and jobs within half mile and one mile walking distances of stations are calculated using network and buffer analysis methods. Results are compared to determine the accuracy benefit of conducting a network analysis rather than the more common buffer analysis. The study looks at ways to boost the number of residents and employees within walking distance by maximizing access around each station. It also quantifies the available land …

Internal Ecologies And The Limits Of Local Biologies: A Political Ecology Of Tuberculosis In The Time Of Aids, Abigail H. Neely

Dartmouth Scholarship

South Africa is known for its high rates of HIV and tuberculosis (TB), where HIV has provided fertile ground for the transmission of TB. Indeed, HIVTB coinfection is widely understood as one of the, if not the, biggest health problems in the country. In practice, doctors and nurses understand that unusual cases of tuberculosis indicate HIV and they make diagnosis and treatment plans accordingly. International treatment standards and protocols inform this practice as doctors pay little attention to individual people and the political, economic, cultural, social, and environmental contexts in which they live. Political ecology, with its nested, place-based analysis, …

Estimating Stormwater Runoff For Community Gardens In New York City, Mara Gittleman

Theses and Dissertations

While much of the literature cites community gardens as providing urban ecosystem services, there is very little research quantifying these benefits. This thesis compares the stormwater runoff rates of urban vacant lots, community gardens, and residential developments in New York City and evaluates community gardens as green infrastructure.

Creation Of Weighted Theissen Polygons Using Python, Colin Spohn

Senior Honors Projects, 2010-2019

Abstract:

This project is an exploration into creating and manipulating Thiessen polygons. Thiessen polygons are zones created around points to show the area closer to each point than any other point in the set. Thiessen polygons are used to extend climate data from individual stations across areas. After creating the new procedure applications of the algorithm were considered.

The manipulation explored in the project focused on allowing the borders of traditional Thiessen polygons to be shifted based on values among the points. These manipulated Thiessen polygons have been dubbed weighted Thiessen polygons.

These weighted Thiessen polygons were created using the …

Mountain Passes And Saddle Points, James Bisgard

All Faculty Scholarship for the College of the Sciences

Variational methods find solutions of equations by considering a solution as a critical point of an appropriately chosen function. Local minima and maxima are well-known types of critical points. We explore methods for finding critical points that are neither local maxima or minima, but instead are mountain passes or saddle points. Criteria for the existence of minima or maxima are well known, but those for mountain passes or saddle points are less well known. We give an accessible treatment of some criteria for the existence of such points (including the mountain pass lemma), as well as describe a method that …

Structure And Composition Of The Kennesaw State University Arboretum: Past And Present, Stephanie A. Roper

Symposium of Student Scholars

The purpose of this study is to determine the trends in composition and structure of the Kennesaw State University (KSU) Arboretum, located on the Kennesaw Campus. To assess the trends, we identified the tree species, and measured the diameter (dbh) and locations of all stems including new growths (i.e. greater than 1cm dbh) in the permanent plot during the summer of 2014. Density, dominance, and frequency values were calculated and all trees were plotted from data collected in 2008, 2010, and 2014. Findings show that there have been an increase in Fagus grandifolia (beech), a significant decline in Cornus florida …

Gold Mining And Unequal Exchange In Western Amazonia: A Theoretical Photo Essay, Gordon L. Ulmer

disClosure: A Journal of Social Theory

I combine fieldwork photography and ethnographic documentation of gold mining in Madre de Dios, Peru, to examine the localized material, social, environmental, and health outcomes of the global gold boom. This 'theoretical photo essay’ examines how local and global forces coalesce around gold mining and influence peoples and environments in Western Amazonia. I use embodiment theory in anthropology, ecological economics, and theories of underdevelopment to understand local consequences of the global gold trade and to elucidate how opulence and the machinations of capital accumulation in economic centers of the world occur at the expense of human lives and environments in …

Monitoring Invasive Plant Species: Summer Internship At Habitat Wildlife Sanctuary, Belmont, Massachusetts, Holly M. Zanoni

Sustainability and Social Justice

Habitat Wildlife Sanctuary, located in Belmont, Massachusetts is a dynamic suburban sanctuary that effectively upholds Mass Audubon’s three-part mission of advocacy, conservation, and education. Invasive plants threaten ecological integrity; however, proactive measures are taken to mitigate further encroachment. This is accomplished by surveying and taking inventory for presence of invasive species, then prioritizing them, and finally by incorporating high priority species into the immediate management strategy. Four invasive plants were formally analyzed using geographic information science during the 2014 growing season: Garlic mustard, Black swallowwort, Japanese knotweed, and Dame’s Rocket. The resulting density maps detected pattern changes from 2011, 2012, …
