Change Points Detected In Decadal And Seasonal Trends Of Outlet Glacier Terminus Positions Across West Greenland, Ashley V. York, Karen E. Frey, Sadegh Jamali, Sarah B. Das

Geography

We investigated the change in terminus position between 1985 and 2015 of 17 marine-terminating glaciers that drain into Disko and Uummannaq Bays, West Greenland, by manually digitizing over 5000 individual frontal positions from over 1200 Landsat images. We find that 15 of 17 glacier termini retreated over the study period, with ~80% of this retreat occurring since 2000. Increased frequency of Landsat observations since 2000 allowed for further investigation of the seasonal variability in terminus position. We identified 10 actively retreating glaciers based on a significant positive relationship between glaciers with cumulative retreat >300 m since 2000 and their average …

Geography

Forests have re-taken centre stage in global conversations about sustainability, climate and biodiversity. Here, we use a horizon scanning approach to identify five large-scale trends that are likely to have substantial medium- and long-term effects on forests and forest livelihoods: forest megadisturbances; changing rural demographics; the rise of the middle-class in low- and middle-income countries; increased availability, access and use of digital technologies; and large-scale infrastructure development. These trends represent human and environmental processes that are exceptionally large in geographical extent and magnitude, and difficult to reverse. They are creating new agricultural and urban frontiers, changing existing rural landscapes and …

'Amageddon': The Unholy Trinity Of Class Monopoly Rent In The Emerald City, Elijah Connor Hansen

EWU Masters Thesis Collection

Intense redevelopment has steamrolled across Seattle’s South Lake Union and Belltown neighborhoods, home to the headquarters of the world’s largest ecommerce corporation, Amazon. After the corporation established a presence in what is now referred to as ‘Amazonia’ in 2007, the surrounding urban landscape underwent a colossal metamorphic overhaul as high-tech and biotech industries, along with bourgeois luxury high rises, replaced old warehouses and empty parking lots. These new industries have attracted tens of thousands of people to the city, resulting in an oversaturated housing supply and an ensuing housing affordability crisis as rents have continued to skyrocket year after year. …

Spatial Multi-Objective Land Use Optimization Toward Livability Based On Boundary-Based Genetic Algorithm: A Case Study In Singapore, Kai Cao, Muyang Liu, Shu Wang, Mengqi Liu, Wenting Zhang, Qiang Meng, Bo Huang

Research Collection School Of Computing and Information Systems

In this research, the concept of livability has been quantitatively and comprehensively reviewed and interpreted to contribute to spatial multi-objective land use optimization modelling. In addition, a multi-objective land use optimization model was constructed using goal programming and a weighted-sum approach, followed by a boundary-based genetic algorithm adapted to help address the spatial multi-objective land use optimization problem. Furthermore, the model is successfully and effectively applied to the case study in the Central Region of Queenstown Planning Area of Singapore towards livability. In the case study, the experiments based on equal weights and experiments based on different weights combination have …

Coal Mining Sector Contribution To Environmental Conditions And Human Development Index In East Kalimantan Province, Kunny Izza Indah Afkarina, Sindhung Wardana, Poerborini Damayanti

Journal of Environmental Science and Sustainable Development

Coal mining has been one of the issues that led to pros and cons in Indonesia. Research shows that mining activities are one of the factors that affect people’s incomes and local and national economic development. However, mining is a lucrative activity that leads to construction booms that attract population growth and lead to deforestation, thus affecting the environmental conditions of a region. The coal mining industry of Indonesian province of East Kalimantan, on the island of Borneo, provides most of the economic base needed to build the infrastructure and provide energy of the country. Kalimantan Province accounts for approximately …

Recent Disruptions In The Timing And Intensity Of Precipitation In Calakmul, Mexico, Sofia Mardero, Birgit Schmook, Zachary Christman, Sarah E. Metcalfe, Betsabé De La Barreda-Bautista

School of Earth & Environment Departmental Research

This study addresses changes in the timing and intensity of precipitation from 1982 to 2016 from three meteorological stations around Calakmul, Mexico, a landscape balancing biodiversity conservation and smallholder agricultural production. Five methods were used to assess changes in precipitation: the Mann-Kendall test of annual and wet season trends; a fuzzy-logic approach to determine the onset of the rainy season; the Gini Index and Precipitation Concentration Index (PCI) to evaluate the temporal distribution of precipitation; Simple Precipitation Intensity Index (SDII) to evaluate precipitation intensity; and the Rainfall Anomaly Index (RAI) to identify the deficit or surplus of rainfall compared with …

Socio-Ecological Interactions In The National Forests And Grasslands Of Central Oregon: A Summary Of Human Ecology Mapping Results, David Banis, Rebecca Mclain, Alicia Milligan, Krystle N. Harrell, Lee Cerveny

This human ecology mapping project generated socio-spatial data layers describing the …

Agronomic Or Contentious Land Change? A Longitudinal Analysis From The Eastern Brazilian Amazon, Stephen Aldrich, Cynthia S. Simmons, Eugenio Arima, Robert T. Walker, Fernando Michelotti, Edna Castro

Department of Earth and Environmental Systems

Since 1984, nearly 1,000 people have been killed in the Brazilian Amazon due to land conflicts stemming from unequal distribution of land, land tenure insecurity, and lawlessness. During this same period, the region experienced almost complete deforestation (< 8% forest cover by 2010). Land conflict exacts a human toll, but it also affects agents’ decisions about land use, the subject of this article. Using a property-level panel dataset covering the period of redemocratization in Brazil (1984) until the privatization of long-term leases in the eastern Amazon (2010), we show that deforestation is affected by land conflict, particularly in cases of expropriation of property for agrarian reform settlement formation. Deforestation on these settlements is much greater when soils are poor for agriculture and when the land has been the object of past conflict. Deforestation and conflict are episodic, and both agronomic drivers and contentious drivers of land change are active in the region. Ultimately, the outcome of these processes of contentious and agronomic land change is substantial deforestation, regardless of who was in possession and control of the land.

There Must Be Something In The Water: Understanding Pfas Contamination Of Groundwater As A National Security Issue, Kylie N. Ford

Student Theses 2015-Present

This report addresses the widespread pollution of domestic groundwater resources with Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) caused by firefighting activities performed at military installations across the United States. Two former military bases in Southeastern Pennsylvania are used as a single case study: the Naval Air Development Center (NADC) in Warminster and the Naval Air Station Joint Reserve Base (NASJRB) in Horsham. Chapter 1 gives a history of domestic military bases from the perspective of the infrastructure buildup and downsizing that occurred over the 20th Century, along with the environmental degradation revealed during brownfield redevelopment. The chapter then gives specifics about …

Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson

United States National Park Service: Publications

Understanding the mechanisms by which populations are regulated is critical for predicting the effects of large-scale perturbations. While discrete mortality events provide clear evidence of direct impacts, indirect pathways are more difficult to assess but may play important roles in population and ecosystem dynamics. Here, we use multi-state occupancy models to analyze a long-term dataset on nesting bald eagles in south-central Alaska with the goal of identifying both direct and indirect mechanisms influencing reproductive output in this apex predator. We found that the probabilities of both nest occupancy and success were higher in the portion of the study area where …

Food Deserts In Urban Areas, Regina Bellian

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This paper illustrates the issue of food deserts faced by urban areas in three parts. Part one focuses on defining food deserts and what exactly the term denotes as well as who is affected by their present existence socially, physically, and economically. Part two presents research on some of the current policies and programs in place to address the issue of food deserts and discusses a few of the difficulties in implementing them. These approaches are then further analyzed for effectiveness in varying regions. Part three explores a handful of alternative methods to combat this urban issue in order to …

A Feasibility Study On The Application Of Tvdi On Accessing Wildfire Danger In The Korean Peninsula, Kwang Nyun Kim, Seung Hee Kim, Myoung Soo Won, Keun Chang Jang, Won Jun Choi, Yun Gon Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

Wildfire is a major natural disaster affecting socioeconomics and ecology. Remote sensing data have been widely used to estimate the wildfire danger with an advantage of higher spatial resolution. Among the several wildfire related indices using remote sensing data, Temperature Vegetation Dryness Index (TVDI) assesses wildfire danger based on both Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST). Although TVDI has physical advantages by considering both weather and vegetation condition, previous studies have shown TVDI does not performed well compare to other wildfire related indices over the Korean Peninsula. In this study we have attempted multiple modification to …

Grandes Interrogações Sobre O Futuro Dos Povos Indígenas Isolados, Conselho Indigenista Missionário

Tipití: Journal of the Society for the Anthropology of Lowland South America

O presente artigo, de autoria coletiva da equipe do Conselho Indigenista Missionário (Cimi), pretende traçar um quadro geral da situação de vulnerabilidade dos povos indígenas em isolamento e contato inicial no Brasil, tendo como referência temporal o ano de 2016. É preocupante o avanço da exploração dos recursos naturais em territórios ocupados por esses povos, principalmente com a mineração e a exploração de madeira, seja dentro de terras indígenas destinadas aos povos em isolamento, em terras indígenas partilhadas por outros povos, ou em territórios onde a proteção ou o reconhecimento pelo Estado não se faz presente.

Territorialidad De Los Grupos Familiares De Pueblos Indígenas En Aislamiento (Pia) En La Región Del Yasuní, Amazonía Ecuatoriana, Roberto Esteban Narváez Collaguazo

Tipití: Journal of the Society for the Anthropology of Lowland South America

El artículo presenta información etnográfica y una interpretación etnológica sobre los Tagaeiri y Taromenane como parte de los grupos familiares en aislamiento que habitan en el Yasuní, su forma de vida tradicional y su territorio, en un contexto de actores externos que inciden en la generación de violencia y de amenaza a su supervivencia. Sobre los pueblos en aislamiento en Ecuador existe información referenciada en datos indirectos que han dado indicios de presencia a partir de registros de rastros e imágenes satelitales y algunos datos directos, como avistamientos, encuentros en la selva, fotografías aéreas y, el principal, encuentros que generaron …

Thinking Through Tubes: Flowing H/Air And Synaesthesia, Stephen P. Hugh-Jones

Tipití: Journal of the Society for the Anthropology of Lowland South America

The tube, as both object and concept, has cropped up from time to time in the ethnography of lowland South America, most notably in Rivière and Lévi-Strauss’s discussions of blowpipes, hair tubes and pottery and in Hill and Wright's writings on Yuruparí flutes and trumpets. Using data from Northwest Amazonia, this paper first seeks to provide a more rigorous definition of the tube as a concept, exploring its various manifestations and relating these to the body as an image of totalization and detotalization. With reference to myths about creation and Yuruparí, the paper then argues that flows from tubes provide …

Good Reasons Or Bad Conscience? Or Why Some Indian Peoples Of Amazonia Are Ambivalent About Eating Meat, Stephen P. Hugh-Jones

Tipití: Journal of the Society for the Anthropology of Lowland South America

Originally written for a conference on meat attended by farmers, anthropologists, people involved in cultural affairs, and other members of the public, and seeking to avoid emphasis on cultural difference, this paper explores common ground between Euro-American and Amerindian ambivalence about meat consumption. Meat-eating raises two shared concerns: an intuitive recognition of the resemblances between humans and animals and an uncomfortable awareness that human life often depends on the death and destruction of other living beings. I suggest that, behind some obvious cultural differences, Amazonian shamanic and ritual procedures aimed at the de-subjectification of meat share points in common with …

The "Uncontacted" As Third Infamy, George Mentore

Tipití: Journal of the Society for the Anthropology of Lowland South America

This paper principally addresses the "problem" of anthropological thinking, that is, on how and why it remains with us and not with the peoples who do not subscribe to our contested regimes of truth. From my research on the topic, it appears we have not achieved any substantial moral progress on the question of exposure to indigenous otherness since the first European "contact." This failure is primarily due to our hardheaded rationalist refusal to accept our inability to access the felt reality of the Other directly. Or, better still, of the failure of our language to obtain the shared reality …

Christianity + Schooling On Nature Versus Culture In Amazonia, Aparecida M. N. Vilaça

Tipití: Journal of the Society for the Anthropology of Lowland South America

Based on the analysis of Evangelical Biblical translations, as well as on the school writing of Wari' (Southwestern Amazonia) students, produced in indigenous secondary school classrooms and at the intercultural university, this article aims to show how, in both church and school, a nature separate from humans is invented with which they should relate in a utilitarian and also contemplative way. Simultaneously nature’s opposite is invented–a culture that excludes animals and subjects them.

Rexistência Nas Fronteiras Do Capitalismo/Colonialismo: A Ecologia Política Do Isolamento E Da Soberania, Felipe Milanez

Tipití: Journal of the Society for the Anthropology of Lowland South America

Ofereço a perspectiva da ecologia política para rever e atualizar a política de “isolamento” e “não-contato” com base nos conceitos de soberania e necropolítica, sugerindo uma nova proposta de prática política para situações de conflitos em territórios ocupados por povos indígenas que resistem à conquista pela guerra e distanciamento. Da perspectiva do estudo dos conflitos ambientais, a ecologia política questiona a noção de isolamento ao inseri-la como parte do sistema mundo capitalista/colonial. Diante do quadro crescente de fascistização social e violência do Estado, cuja pressão sobre os territórios tornou-se ainda mais intenso, é a morte e a vida destes coletivos …
