From Land Grab To Agrarian Transition? Hybrid Trajectories Of Accumulation And Environmental Change On The Cambodia–Vietnam Border, Timothy Gorman, Alice Beban Dec 2016

From Land Grab To Agrarian Transition? Hybrid Trajectories Of Accumulation And Environmental Change On The Cambodia–Vietnam Border, Timothy Gorman, Alice Beban

Department of Sociology Faculty Scholarship and Creative Works

In recent years, thousands of Vietnamese migrant farmers have crossed the border into Cambodia and leased land for export-oriented rice and shrimp production. Based on case studies in two Cambodian border provinces, we argue that these land transfers represent an intersection of broader processes of agrarian change that is re-shaping the Cambodian borderlands into a hybrid socio-ecological zone. Cambodian landlords and intermediaries use unequal access to politico-legal authority and the exclusionary power of the border to leverage control over their migrant tenants, thereby capturing a significant portion of the surplus from the migrants’ high-value commodity production systems and potentially creating …


Ethnobiology In The City: Embracing The Urban Ecological Moment, Marla R. Emery, Patrick T. Hurley Dec 2016

Ethnobiology In The City: Embracing The Urban Ecological Moment, Marla R. Emery, Patrick T. Hurley

Environment and Sustainability Faculty Publications

More than half the world's human population resides in cities (United Nations Economic and Social Affairs Population Division 2015). Unpacking this singular statistic, it becomes clear that people come to live in urban environments via numerous routes. Some have lived in cities all their lives and are descendants of city dwellers. In other cases, cities spread and encircle them (Hurley et al. 2008; Unnikrishnan and Nagendra 2015). Increasingly, rural residents are national and transnational migrants to cities, pushed by armed conflict, natural disasters, and economic need or opportunity (United Nations Economic and Social Affairs Population Division 2013). In the case …


Coupled Impacts Of Climate And Land Use Change Across A River-Lake Continuum: Insights From An Integrated Assessment Model Of Lake Champlain's Missisquoi Basin, 2000-2040, Asim Zia, Arne Bomblies, Andrew W.

Global climate change (GCC) is projected to bring higher-intensity precipitation and higher-variability temperature regimes to the Northeastern United States. The interactive effects of GCC with anthropogenic land use and land cover changes (LULCCs) are unknown for watershed level hydrological dynamics and nutrient fluxes to freshwater lakes. Increased nutrient fluxes can promote harmful algal blooms, also exacerbated by warmer water temperatures due to GCC. To address the complex interactions of climate, land and humans, we developed a cascading integrated assessment model to test the impacts of GCC and LULCC on the hydrological regime, water temperature, water quality, bloom duration and severity …


Estimating Economic Losses To Tourism In Africa From The Illegal Killing Of Elephants, Robin Naidoo, Brendan Fisher, Andrea Manica, Andrew Balmford Nov 2016

Estimating Economic Losses To Tourism In Africa From The Illegal Killing Of Elephants, Robin Naidoo, Brendan Fisher, Andrea Manica, Andrew Balmford

Rubenstein School of Environment and Natural Resources Faculty Publications

Recent surveys suggest tens of thousands of elephants are being poached annually across Africa, putting the two species at risk across much of their range. Although the financial motivations for ivory poaching are clear, the economic benefits of elephant conservation are poorly understood. We use Bayesian statistical modelling of tourist visits to protected areas, to quantify the lost economic benefits that poached elephants would have delivered to African countries via tourism. Our results show these figures are substantial (∼USD $25 million annually), and that the lost benefits exceed the anti-poaching costs necessary to stop elephant declines across the continent's savannah …


Crime In The Built Urban Environment: Exploring The Impact Of Road Networks And Land Use On Residential Burglary Patterns, Kathryn Wuschke, Justin Song, Valerie Spicer Nov 2016

Crime In The Built Urban Environment: Exploring The Impact Of Road Networks And Land Use On Residential Burglary Patterns, Kathryn Wuschke, Justin Song, Valerie Spicer

Criminology and Criminal Justice Faculty Publications and Presentations

For decades, environmental criminology theory has emphasized the connections between the built urban environment and criminal activity. The urban landscape determines both the origins and destinations of everyday journeys from home to work, school, shoppingor entertainment areas, and it provides the pathways on which residents travel. As such, the built environment guides and limits the locations that offenders may search within in order to identify potential criminal opportunities. For these reasons, access and proximity to major roads, as well as key local activity nodes such as shopping malls, transit stations and schools, have been frequently found to be an important …

Revolution And Education, Lilia D. Monzó, Peter Mclaren

Education Faculty Articles and Research

Denied the right to recognize patterns of violence and their relationship to class and specifically to the capitalist mode of production through an institutionalized historical amnesia, we live our lives as mere passengers on a train that stops at death’s door. In the self-proclaimed greatest super power, the United States, the mythical alliance to democracy serves to obfuscate its systematic plundering of life and earth in service to the transnational capitalist class. We have been brainwashed through state and corporate-sponsored lies, myth, and a national zealotry to forget and continue to repeat the atrocities of our past. We have been …

E-Cigarette Use Among Students And E-Cigarette Specialty Retailer Presence Near Schools, Georgiana Bostean, Catherine M. Crespi, Patsornkarn Vorapharuek, William J. Mccarthy

Sociology Faculty Articles and Research

Objective. This study examined the association between presence of e-cigarette specialty retailers near schools and e-cigarette use among middle and high school students in Orange County (OC), CA.

Methods. The OC subsample of the 2013-2014 California Healthy Kids Survey (N=67,701) was combined with geocoded e-cigarette retailers to determine whether a retailer was present within one-quarter mile of each public school in OC. Multilevel logistic regression models evaluated individual-level and school-level e-cigarette use correlates among middle and high school students.

Results. Among middle school students, the presence of an e-cigarette retailer within one-quarter mile of their school predicted …


Disaggregating The Evidence Linking Biodiversity And Ecosystem Services, Taylor H. Ricketts, Keri B. Watson, Insu Koh, Alicia M. Ellis, Charles C. Nicholson, Stephen Posner, Leif L. Richardson, Laura J. Sonter Oct 2016

Disaggregating The Evidence Linking Biodiversity And Ecosystem Services, Taylor H. Ricketts, Keri B. Watson, Insu Koh, Alicia M. Ellis, Charles C. Nicholson, Stephen Posner, Leif L. Richardson, Laura J. Sonter

Rubenstein School of Environment and Natural Resources Faculty Publications

Ecosystem services (ES) are an increasingly popular policy framework for connecting biodiversity with human well-being. These efforts typically assume that biodiversity and ES covary, but the relationship between them remains remarkably unclear. Here we analyse >500 recent papers and show that reported relationships differ among ES, methods of measuring biodiversity and ES, and three different approaches to linking them (spatial correlations, management comparisons and functional experiments). For spatial correlations, biodiversity relates more strongly to measures of ES supply than to resulting human benefits. For management comparisons, biodiversity of â € service providers' predicts ES more often than biodiversity of functionally …

Climate Change, Smart Growth, Racial Oppression, And White Privilege, Laura Stivers Oct 2016

Climate Change, Smart Growth, Racial Oppression, And White Privilege, Laura Stivers

Collected Faculty and Staff Scholarship

In this paper I will examine how people of differing environmental perspectives—namely anti-growth preservationists and environmental justice advocates—frame their responses to smart growth, using Marin County in the San Francisco Bay Area as a case study. Then I will offer a race analysis of these frameworks based on the thesis that to address climate change through smart growth we need to challenge the ways certain groups try to retain their white privilege. As foundation for this thesis I will develop the norms of reparations and restoration to argue for an equitable smart growth approach that entails structural transformation to address …


Independent Study Project: Investigation Into The Implications Of Zooarchaeological Studies For Climate Reconstruction In The North Atlantic; Zooarchaeological Research At The Agricultural University Of Iceland, Reykjavík, Hazel Cashman Oct 2016

Independent Study Project: Investigation Into The Implications Of Zooarchaeological Studies For Climate Reconstruction In The North Atlantic; Zooarchaeological Research At The Agricultural University Of Iceland, Reykjavík, Hazel Cashman

Independent Study Project (ISP) Collection

Zooarchaeology, the study of animal remains from archaeological sites, is crucial to the understanding of human interaction with the environment in the North Atlantic region and in Iceland, where the archaeological record is quite rich (Dugmore et al., 2005). Since its inception, zooarchaeology has drawn methods and concepts from both the natural and social sciences, as well as from history and the humanities, to inform an interdisciplinary understanding of the interactions between humans and their environments and the consequences of these interactions for humans and animals (Reitz and Wing, 2008). In this way, zooarchaeology can inform discussions about historical anthropogenic …

Continuing Efforts To Alleviate "Orange Pain" An Internship With The Da Nang Association Of Victims Of Agent Orange/Dioxin, Loan Heilner

Independent Study Project (ISP) Collection

This year marked the 55th anniversary of Vietnam’s Agent Orange Disaster. Decades after the end of the war, Vietnamese people are still largely being affected by the remnants of the United States’ Agent Orange herbicide sprays. Dioxin chemical has now been confirmed detrimental to human and environmental well-being, but unfortunately it still remains in high concentrations in certain areas of Vietnam. Dioxin chemical is passed on through genetics to new generations, but one of the leading causes of dioxin-related health defects today are due to environmental residue. In Da Nang, Agent Orange was stored and loaded at the local airbase …


Water Resource Change And Management: Implications Of Climate Change And Water Resource Management For Pastoral Herders In Bayan Ulgii, Rachel Ryan Oct 2016

Water Resource Change And Management: Implications Of Climate Change And Water Resource Management For Pastoral Herders In Bayan Ulgii, Rachel Ryan

Independent Study Project (ISP) Collection

Mongolia is the 8th most vulnerable country in the world to climate change. The water regime of Mongolia is therefore experiencing intensive change with significant effects in the availability, distribution, and security of water resources. The implications of this change are exacerbated when aligned with poor water resource management, an issue that is prevalent as water regime change challenges current water management systems. These implications specifically affect the vulnerable rural population of Mongolian herders who maintain the practice of nomadic pastoralism. In the western province of Bayan Ulgii, the change in the numerous glaciers and other water resources that are …

Geospasial Indonesia: The Utilization Of Spatial Data Through Geographic Information Systems Across Indonesia In Various Environmental Contexts, Kaitlyn Bretz Oct 2016

Geospasial Indonesia: The Utilization Of Spatial Data Through Geographic Information Systems Across Indonesia In Various Environmental Contexts, Kaitlyn Bretz

Independent Study Project (ISP) Collection

Spatial planning and mapping in Indonesia have had a precarious history for the past several decades. Laws controlling the creation of maps for land use planning have fluctuated greatly between executive administrations and the country is still struggling to create a single, unified national map. With the One Map Policy the future of mapping is optimistic, but in the meantime spatial data analyses are lacking. Geographic information systems (GIS) is a computerized system for the capture, storage, querying, analysis, and display of spatial data, and is used predominately by the government, private companies, and nongovernmental organizations (NGOs) across Indonesia. Community …


A Review Of Climate Change Induced Effects On Avian Prey Species And Their Consequences For Arctic Fox Populations Of Western Iceland, Mikala Jordan Oct 2016

A Review Of Climate Change Induced Effects On Avian Prey Species And Their Consequences For Arctic Fox Populations Of Western Iceland, Mikala Jordan

Independent Study Project (ISP) Collection

Island arctic fox populations are considered to carry the future wellbeing of the global population. Iceland has an island population with two arctic fox eco-types: western/coastal and eastern/inland. The western fox population is protected by the Hornstrandir Nature Reserve; no such protection exists for the eastern fox population. Food sources in both regions differ from each other and vary from summer to winter, but reliable and ample winter time food sources are the most critical for fox population’s survival. A literature review on arctic foxes and their prey species in the face of climate change is important for understanding possible …


Relocation, Resistance And Resilience: Squatter Community Responses To Government Intervention For Urban Development In Kathmandu, Reilly Brooks Oct 2016

Relocation, Resistance And Resilience: Squatter Community Responses To Government Intervention For Urban Development In Kathmandu, Reilly Brooks

Independent Study Project (ISP) Collection

“Squatting,” or residing on public land illegally, is a modern urban phenomenon in developing countries. This phenomenon is attributed to rapid urbanization due to rural-to-urban migration, which leads to rising costs of living, exclusionary housing markets, a lack of affordable housing and urban inequality. Ultimately, unplanned urban growth encourages the formation and expansion of squatter settlements. These settlements are commonly characterized as slum due to the impoverished living conditions, highly congested spaces and lack of public services (water, sanitation, education, etc.) Without land certificates, squatters are denied their right to adequate housing and land security, which should be protected by …


The Importance Of Nature: An Investigation On How Geography Influences Well-Being, Christina Cobb Oct 2016

The Importance Of Nature: An Investigation On How Geography Influences Well-Being, Christina Cobb

Independent Study Project (ISP) Collection

The objective of this community service project (CSP) was to study how a community’s location, specifically within nature, influences their well-being. I hoped to see how the community’s location, within Chapada Diamantina national park, influences the many ways health is promoted, and how these ways are affected by their location within nature. This project was built upon a review of the literature, which found that there is a theoretical basis for the notion that contact with nature is beneficial, a term deemed Biophilia. There is a robust body of academic research that highlights the health benefits deriving from contact …


Cultural Variability In The Link Between Environmental Concern And Support For Environmental Action, Kimin Eom, Heejung S. Kim, David K. Sherman, Keiko Ishii Oct 2016

Cultural Variability In The Link Between Environmental Concern And Support For Environmental Action, Kimin Eom, Heejung S. Kim, David K. Sherman, Keiko Ishii

Research Collection School of Social Sciences

Research on sustainability behaviors has been based on the assumption that increasing personal concerns about the environment will increase proenvironmental action. We tested whether this assumption is more applicable to individualistic cultures than to collectivistic cultures. In Study 1, we compared 47 countries (N = 57,268) and found that they varied considerably in the degree to which environmental concern predicted support for proenvironmental action. National-level individualism explained the between-nation variability above and beyond the effects of other cultural values and independently of person-level individualism. In Study 2, we compared individualistic and collectivistic nations (United States vs. Japan; N = 251) …


Welcome To The Streets: Tracing The Development Of Street Art In Nepal Since 2010, Malik Earle Oct 2016

Welcome To The Streets: Tracing The Development Of Street Art In Nepal Since 2010, Malik Earle

Independent Study Project (ISP) Collection

Graffiti is a process. There really is no beginning or ending to a piece. Graffiti art is practicing a design, bringing it to a wall, letting it take shape, and allowing it to interact with the environment. What makes graffiti unique, among other things, is its interaction with the environment. When international graffiti influences and local conditions drove inspired artists to bring their art to the streets, a new art form emerged in Nepal. “Local conditions” labels the forces ranging from personal drive to the history of public art in Nepal, which fuel the movement. The present study aims at …


El Rol De Los Supermercados Chinos En La Integración Social De La Población China En Buenos Aires / The Role Of Chinese Supermarkets In The Social Integration Of The Chinese Population In Buenos Aires, Dana Marrero Oct 2016

El Rol De Los Supermercados Chinos En La Integración Social De La Población China En Buenos Aires / The Role Of Chinese Supermarkets In The Social Integration Of The Chinese Population In Buenos Aires, Dana Marrero

Independent Study Project (ISP) Collection

Aunque la inmigración china es algo relativamente nuevo en la historia de Argentina, las personas de aquel país han tenido una presencia fuerte en la sociedad de Buenos Aires, la ciudad Capital. En gran parte, esto es debido al nicho económico en el que muchos de los trabajadores chinos se han concentrado: los supermercados. Los pequeños mercados de barrio manejados por dueños chinos son tan comunes que a menudo los porteños simplemente dicen frases como “voy al chino” para referirse a estos comercios. Y con razón: en el 2011, aproximadamente el 35% de todos los mercados de Argentina pertenecía a …

Opportunities For Biodiversity Gains Under The World's Largest Reforestation Programme, Fangyuan Hua, Xiaoyang Wang, Xinlei Zheng, Brendan Fisher, Lin Wang, Jianguo Zhu, Ya Tang, Douglas W. Yu, David S. Wilcove

Rubenstein School of Environment and Natural Resources Faculty Publications

Reforestation is a critical means of addressing the environmental and social problems of deforestation. China's Grain-for-Green Program (GFGP) is the world's largest reforestation scheme. Here we provide the first nationwide assessment of the tree composition of GFGP forests and the first combined ecological and economic study aimed at understanding GFGP's biodiversity implications. Across China, GFGP forests are overwhelmingly monocultures or compositionally simple mixed forests. Focusing on birds and bees in Sichuan Province, we find that GFGP reforestation results in modest gains (via mixed forest) and losses (via monocultures) of bird diversity, along with major losses of bee diversity. Moreover, all …


Climate Change And Vulnerability To Poverty: An Empirical Investigation In Rural Indonesia, Tomoki Fujii Sep 2016

Climate Change And Vulnerability To Poverty: An Empirical Investigation In Rural Indonesia, Tomoki Fujii

Research Collection School Of Economics

Scientists estimate that anthropogenic climate change leads to increased surface temperature, sea-level rise, more frequent and significant extreme weather and climate events, among others. In this study, we investigate how climate change can potentially change the vulnerability to poverty using a panel data set in Indonesia. We focus on the effect of drought and flood, two of the commonly observed disasters there. Our simulation results indicate that vulnerability to poverty may increase substantially as a result of climate change in Indonesia.


Multiple Post-Domestication Origins Of Kabuli Chickpea Through Allelic Variation In A Diversification-Associated Transcription Factor, R. Varma Penmetsa, Noelia Carrasquilla-Garcia, Emily M.

Multiple Post-Domestication Origins Of Kabuli Chickpea Through Allelic Variation In A Diversification-Associated Transcription Factor, R. Varma Penmetsa, Noelia Carrasquilla-Garcia, Emily M. Bergmann, Lisa Vance, Brenna Castro, Mulualem T. Kassa, Birinchi K. Sarma, Subhojit Datta, Andrew D. Farmer, Jong Min Baek, Clarice J. Coyne, Rajeev K. Varshney, Eric J.B. Von Wettberg, Douglas R. Cook

College of Agriculture and Life Sciences Faculty Publications

Chickpea (Cicer arietinum) is among the founder crops domesticated in the Fertile Crescent. One of two major forms of chickpea, the so-called kabuli type, has white flowers and light-colored seed coats, properties not known to exist in the wild progenitor. The origin of the kabuli form has been enigmatic. We genotyped a collection of wild and cultivated chickpea genotypes with 538 single nucleotide polymorphisms (SNPs) and examined patterns of molecular diversity relative to geographical sources and market types. In addition, we examined sequence and expression variation in candidate anthocyanin biosynthetic pathway genes. A reduction in genetic diversity and extensive genetic …


Concepts And Measurement Of Vulnerability To Poverty And Other Issues: A Review Of Literature, Tomoki Fujii Sep 2016

Concepts And Measurement Of Vulnerability To Poverty And Other Issues: A Review Of Literature, Tomoki Fujii

Research Collection School Of Economics

This paper reviews the growing body of literature on vulnerability. We first provide a survey of existing studies on the concepts and measurements of vulnerability to poverty by classifying them into welfarist, expected poverty, and axiomatic approaches. We then review a number of empirical studies on vulnerability to poverty in Asia and elsewhere. This review shows that poverty and vulnerability are related, but different, and that key determinants of vulnerability often include education and location. We also briefly review other areas of vulnerability analysis such as vulnerability to climate change and offer various policy implications arising from vulnerability analysis.


A Review Of Needs And Challenges Facing Unaccompanied Alien Children (Uac) Released Into U.S. Communities, Dorothy L. Mcleod Aug 2016

A Review Of Needs And Challenges Facing Unaccompanied Alien Children (Uac) Released Into U.S. Communities, Dorothy L. Mcleod

Center for the Human Rights of Children

Immigrant children (<18 years) who enter the United States alone and without legal status are defined as unaccompanied alien children (UAC ), according to United States law. Between 2013 and 2015, the number of unaccompanied immigrant children arriving at the United States-Mexico border increased dramatically, reaching a peak of over 55,000 in FY 2014. While a number of research and policy documents detail the movement of youth through the immigration system, little is known about this population after their release to sponsors in the U.S. The current research brief synthesizes the existing research using a multi-disciplinary approach. We have chosen to prioritize peer-reviewed research, but have also included information from governmental and NGO reports. Each of the following sections summarizes the research on a different aspect of youth’s postr-elease adjustment to life in the United States. We conclude the report with a list of unanswered research questions.

Pyrogenic Fuels Produced By Savanna Trees Can Engineer Humid Savannas, William J. Platt, Darin P. Ellair, Jean M. Huffman, Stephen E. Potts, Brian Beckage Aug 2016

Pyrogenic Fuels Produced By Savanna Trees Can Engineer Humid Savannas, William J. Platt, Darin P. Ellair, Jean M. Huffman, Stephen E. Potts, Brian Beckage

College of Agriculture and Life Sciences Faculty Publications

Natural fires ignited by lightning strikes following droughts frequently are posited as the ecological mechanism maintaining discontinuous tree cover and grass-dominated ground layers in savannas. Such fires, however, may not reliably maintain humid savannas. We propose that savanna trees producing pyrogenic shed leaves might engineer fire characteristics, affecting ground-layer plants in ways that maintain humid savannas. We explored our hypothesis in a high-rainfall, frequently burned pine savanna in which the dominant tree, longleaf pine (Pinus palustris), produces resinous needles that become highly flammable when shed and dried. We postulated that pyrogenic needles should have much greater influence on fire characteristics …


Of Migrants And Middlemen: Cultivating Access And Challenging Exclusion Along The Vietnam–Cambodia Border, Timothy Gorman, Alice Beban Jul 2016

Of Migrants And Middlemen: Cultivating Access And Challenging Exclusion Along The Vietnam–Cambodia Border, Timothy Gorman, Alice Beban

Department of Sociology Faculty Scholarship and Creative Works

In a possible sign of a new trend in Southeast Asia, economic pressures are driving smallholder shrimp farmers from Vietnam's Mekong Delta across the Cambodian border in search of new land. Building from ethnographic research with Vietnamese shrimp farmers in Kampot province, Cambodia, this paper explores the structures, mechanisms, and relations that facilitate and impede the ability of Vietnamese migrants to gain and maintain access to land in Cambodia. The Vietnamese migrants in our study bring capital and farming skills, but their ambiguous legal status and their lack of social networks and experience with the terms of access in Cambodia …
