Coal Mining Sector Contribution To Environmental Conditions And Human Development Index In East Kalimantan Province, Kunny Izza Indah Afkarina, Sindhung Wardana, Poerborini Damayanti Dec 2019

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 …

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 Dec 2019

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.


Breaking Ground On New Agricultural Models: Industrial Agriculture And The Local Food Movement, Elizabeth Nealon Dec 2019

Breaking Ground On New Agricultural Models: Industrial Agriculture And The Local Food Movement, Elizabeth Nealon

Student Theses 2015-Present

This paper discusses and examines the longstanding issues surrounding industrial food production as it currently exists and the various ways that purpose-driven enterprises and environmentally-conscious consumers in the United States have been able to steer food production in a more sustainable direction. Over the course of the technological revolution, people living in metropolitan areas have become so distanced from farms and the processes of food production that many are ignorant of the realities of the food industry. Chapter 1 addresses these issues by presenting quantitative data that lays out a timeline of the evolution of the food and agriculture industry …

Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson Dec 2019

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 …

Rising Seas Are Coming For The Dead, Kristen Ancillotti Dec 2019

Rising Seas Are Coming For The Dead, Kristen Ancillotti

Capstones

When people think of preparing for a disaster, they focus on how to safeguard homes, prevent damage to roads, and create efficient flood drainage. But as sea levels rise, it’s not only the living that are affected. Coastal cemeteries are washing away or slowly turning into marshland, and in some instances, caskets can be seen floating in the streets after storms. Projections from NOAA indicate that the global mean sea level is likely to rise at least 12 inches by 2100, and in a worst case scenario in which greenhouse gas emissions are at their highest, as high as 8.2 …


A Geographical Analysis Of Gentrification And The Changing Foodscape In Seattle 2010-2017, Alice Tiffany, Michele Romolini Dec 2019

A Geographical Analysis Of Gentrification And The Changing Foodscape In Seattle 2010-2017, Alice Tiffany, Michele Romolini

Honors Thesis

Anguelovski defines food privilege as “the exclusive access to desirable ‘natural’ and fresh food thanks to one’s economic, cultural, and political power” (Anguelovski 2015a). Previous studies have demonstrated that access to fresh, healthy, affordable food is correlated with socioeconomic status (LA Food Policy Council 2017; Walker et al. 2010; Alkon & Agyeman 2011; Raja et al. 2008). However, as is being increasingly noted, the introduction of environmental amenities, such as farmers markets and community gardens, can have unintended consequences and trigger environmental gentrification (Kern 2015; Pearsall 2010; Eckerd 2011; Curran & Hamilton 2012; Wolch et al. 2014; Alkon & Cadji …

Plastic Packaging And The Associated Environmental Challenges. A Case For A California Plastic Packaging Framework, Zahra Ghayour-Kelly Dec 2019

Plastic Packaging And The Associated Environmental Challenges. A Case For A California Plastic Packaging Framework, Zahra Ghayour-Kelly

Master's Projects and Capstones

While plastic has become an almost irreplaceable material in modern life, continuous new evidence of its adverse effects on human health and the environment is emerging. Currently there are limited options to address the negative impacts of plastic production and disposal on the environment. Plastic production and distribution creates greenhouse gas emissions. Additionally, limited end-of-life waste management options for the growing plastic waste stream place a great burden on local communities and the environment. Among the many products made of plastic, packaging is the largest and fastest-growing sector. Plastic packaging that is multilayered and fused is very commonly used, yet …

Is Our Coal-Onial Era Ending Anytime Soon?, Hadiqa Faraz Dec 2019

Is Our Coal-Onial Era Ending Anytime Soon?, Hadiqa Faraz

Undergraduate Economic Review

In this paper, I estimate the long-run co-integrated relationship between energy demand and economic growth for 20 countries from the year 2000 to 2016. I use panel unit-root and heterogeneous panel co-integration tests to test for non-stationarity of the panels and to determine whether there is a long-run link between energy consumption and GDP per capita. The estimated model uses a first-difference OLS model to estimate income elasticity of energy demand; the empirical results of this model show that there is a long-run relationship between energy consumption per capita and GDP per capita. In the long-term, on average, with 1% …


Thermodynamic Model Of Co2 Deposition In Cold Climates, Sandra K. S. Boetcher, Ted Von Hippel, Matthew J. Traum Dec 2019

Thermodynamic Model Of Co2 Deposition In Cold Climates, Sandra K. S. Boetcher, Ted Von Hippel, Matthew J. Traum

Publications

A thermodynamic model, borrowing ideas from psychrometric principles, of a cryogenic direct-air CO2-capture system utilizing a precooler is used to estimate the optimal CO2 removal fraction to minimize energy input per tonne of CO2. Energy costs to operate the system scale almost linearly with the temperature drop between the ingested air and the cryogenic desublimation temperature of CO2, driving siting to the coldest accessible locations. System performance in three Arctic/Antarctic regions where the proposed system can potentially be located is analyzed. Colder ambient temperatures provide colder system input air temperature yielding lower CO2 removal energy requirements. A case is also …


The Treadmill Of Information: Development Of The Information Society And Carbon Dioxide Emissions, Joseph M. Simpson, Riley E. Dunlap, Andrew S. Fullerton Dec 2019

The Treadmill Of Information: Development Of The Information Society And Carbon Dioxide Emissions, Joseph M. Simpson, Riley E. Dunlap, Andrew S. Fullerton

Sociology Faculty Publications (Archived)

The world is facing a crisis of global warming due to the release of CO2 and other greenhouse gasses by human activities. Many scholars and stakeholders argue that information and communication technology (ICT) development will mitigate CO2 emissions. Advocacy of technological solutions to CO2 mitigation is consistent with ecological modernization theory's assertion that reflexive societies will modernize sustainably. In contrast, we define the “treadmill of information” as the unique contribution of ICT development to environmental degradation. We examine the impact of ICT development on total CO2 emissions and source-sector emissions from electricity, buildings, manufacturing, and transportation …


Do Changing Resource Conditions Displace Anglers? A Study Of Contingent Travel Behaviors And Substitution Patterns On Minnesota’S North Shore, Adam Hestetune Dec 2019

Do Changing Resource Conditions Displace Anglers? A Study Of Contingent Travel Behaviors And Substitution Patterns On Minnesota’S North Shore, Adam Hestetune

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Angling in Minnesota’s North Shore faces unique threats from the impacts of climate change. These impacts, such as changes in the presence and/or abundance of specific species, present management challenges which might also influence the demand for recreational angling throughout the region. Anglers’ adaptations to climate change in the North Shore region could shift densities, timing, and spatial use of the region’s fish populations, increasing the stress on ecological systems. Developing an empirically-grounded understanding of the contingent behaviors of anglers is imperative if the region’s fish populations are to be managed sustainably. Using a travel cost model, we measured the …

Political Polarization And Long-Term Change In Public Support For Environmental Spending, Eric W. Johnson, Philip Schwadel Dec 2019

Political Polarization And Long-Term Change In Public Support For Environmental Spending, Eric W. Johnson, Philip Schwadel

Department of Sociology: Faculty Publications

Public support for environmental protection has evinced declines in recent years that are widely attributed to growing antipathy among self-identified Republicans. Fractures in what was long considered broad and enduring support for the environment in the United States have called attention to the broader sociopolitical context in which individual opinion on the environment is formed, and especially the role of political parties and their leaders in shaping opinion. Empirical analyses of environmental support, however, remain strongly focused on individual-level correlates of support. We apply recent methodological advances in age-period-cohort models to scrutinize changes in Americans’ willingness to pay more for …


Current And Historic Visitor Experiences In Coastal Alaskan Wilderness: Visitor Motivations And Experience Quality In Glacier Bay National Park & Preserve, Gabriella R. Furr Dec 2019

Current And Historic Visitor Experiences In Coastal Alaskan Wilderness: Visitor Motivations And Experience Quality In Glacier Bay National Park & Preserve, Gabriella R. Furr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Visitors to parks and protected areas (PPAs) engage in a variety of activities and choose different modes of travel, especially when the location itself has few limitations, such as open-water settings with relatively few backcountry visitors. Managers must understand why visitors are recreating in a particular place and the quality of their experiences in order to offer appropriate and meaningful opportunities. This study seeks to better understand visitor motivations (the “why”), to develop and measure effective indicators for evaluating the quality of visitor experiences, and to contextualize these findings with a unique investigation of historical Glacier Bay National Park data. …

Globally, protected areas offer refugia for a broad range of taxa including threatened and endangered species. In the United States (US), the National Park Service (NPS) manages public lands to preserve biodiversity, but increasing park visitation and development of surrounding landscapes increase exposure to and effects from bioactive contaminants. The risk (exposure and hazard) to NPS protected-stream ecosystems within the highly urbanized southeast region (SER) from bioactive contaminants was assessed in five systems based on 334 pesticide and pharmaceutical analytes in water and 119 pesticides in sediment. Contaminant mixtures were common across all sampled systems, with approximately 24% of the …
