Celebrating Extinction? The Disconnect Between Reality And Media Representation Of Bluefin Tuna In Japan, Gene Fukui

Honors Papers

The Japanese media has perpetually glorified Bluefin tuna as the symbol of Japanese culture, cuisine, and national identity. Meanwhile, Bluefin tuna stocks are plummeting due to overfishing, and some species are international recognized as endangered. Blame is primarily placed on Japan, as the nation consumes 80% of Bluefin in the world and the government has admitted to overfishing several times. This has led to international environmental organizations and Western governments continually criticizing Japan for its unsustainable fishing practices.

This paper provides an explanation as to why there is no domestic movement within Japan to put an end to overfishing: the …

Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman

All Master's Theses

In response to a dual problem of critical water scarcity and rapid population growth, leaders of metropolitan Las Vegas implemented a region-wide, internationally marketed sustainability campaign. Preliminary studies found that, while sustainability policy attains its rhetorical goals, solutions initiated not only perpetuate but also purposefully expand the original dual problem to justify continuous water resource acquisitions. To examine this sustainability conundrum constructed by leadership—problem-perpetuation rather than problem-resolution—a critical examination in resource management asked two basic questions: what is being sustained and by what means? Via this inquiry, specific processes by which leaders perpetuate problems can be identified; and, so-informed, new …

Science-Fictional North Korea: A Defective History, Seo-Young J. Chu

Publications and Research

Kafkaesque, Orwellian, eerie, surreal, bizarre, grotesque, alien, wacky, fascinating, dystopian, illusive, theatrical, antic, haunting, apocalyptic: these are just a few of the vaguely science-fictional adjectives that are now associated with North Korea. At the same time, North Korea has become an oddly convenient trope for a certain aesthetic – an uncanny opacity; an ominous mystique – that many writers and artists have exploited to generate striking science-fictional effects in texts with little or no connection to North Korean reality. (The 2002 Bond film Die another Day, for example, draws from North Korea’s science-fictional aura to animate North Korean super-villains who …

Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distribution, abundance, and diversity of life on Earth have been greatly shaped by human activities. This includes the geographic expansion of parasites; however, measuring the extent to which humans have influenced the dissemination and population structure of parasites has been challenging. In-depth comparisons among parasite populations extending to landscape-level processes affecting disease emergence have remained elusive. New research methods have enhanced our capacity to discern human impact, where the tools of population genetics and molecular epidemiology have begun to shed light on our historical and ongoing influence. Only since the 1990s have parasitologists coupled morphological diagnosis, long considered the …

Modeling Black Bear Population Dynamics In A Human-Dominated Stochastic Environment, David L. Lewis, Stewart W. Breck, Kenneth R. Wilson, Colleen T. Webb

United States Department of Agriculture Wildlife Services: Staff Publications

Many large carnivore populations exist in human-influenced stochastic environments where availability of natural food sources vary annually and anthropogenic food sources can supplement energetic demands, but at a potential demographic cost due to human–wildlife conflict and subsequent conflict management. Understanding how these competing factors influence a population is complex and difficult to study, but here we demonstrate the utility of using a stochastic projection matrix model and perturbation analysis to gain insight into this problem. We modeled a black bear population subjected to stochastic failures of fruiting and masting species, but with access to garbage in urban environments.We parameratized our …

Assessing Farmers’ And Landowners’ Attitudes Towards Environmental Sustainability And Their Motivations Towards Walking Tourism In Sheep’S Head Way, Co. Cork, Gráinne Dwyer

Irish Business Journal

Numerous studies within academic literature examine motivations of walkers engaging with nature-based tourism activities, such as hillwalking.

Unintended Outcomes Of Farmers' Adaptation To Climate Variability: Deforestation And Conservation In Calakmul And Maya Biosphere Reserves, Claudia Rodriguez-Solorzano

Dartmouth Scholarship

Minimizing the impact of climate change on farmer livelihoods is crucial, but adaptation efforts may have unintended consequences for ecosystems, with potential impacts on farmers’ welfare. Unintended outcomes of climate adaptation strategies have been widely discussed, however, empirical exploration has been neglected. Grounded in scholarship on climate adaptation, environmental governance, social–ecological systems, and land-use change, this paper studies whether farmers’ climate adaptation contributes to deforestation or forest conservation. The paper draws on interviews with 353 farmers from 46 communities in Calakmul Biosphere Reserve in Mexico and Maya Biosphere Reserve in Guatemala.

Resolving The Conflict Between Mining And Sustainability, David A.C. Manning

Applied Environmental Research

Mining is essential for human health and prosperity, and is increasing as the global populationgrows. The need for minerals appears to conflict with what is commonly understood as 'sustainability',as geological resources are non-renewable on a human timescale. However, the Brundtland definition of sustainability includes the concept of 'needs', implying that there has to be a balanced approach thatconsiders poverty alleviation. It identifies the three pillars of sustainability: economic, social and environmental.In the UK, mining has a legacy extending back over 6000 years. The approach taken to sustainability will be illustrated by 3 examples from northern England. In the 18thand 19thcenturies, …

Artisanal-Small Scale Mining In Myanmar, Aung Kyin

Applied Environmental Research

In many parts of the world, artisanal or small-scale mining activities are at least as important as large-scale mining activities. The numbers of people employed are actually considerably greater than in large companies. In 2002, an estimated 13 million people a large percentage of those are women and children are artisanal and small scale miners operating mainly in developing countries. Although the numbers of small-scale miners and their dependents are estimated at up to 80-100 million people, governments are frequently reluctant to give legal recognition to artisanal miners [1].This paper discusses approaches to developthe Artisanal - Small Scale Mining (ASM) …

Sustainable Mining In Myanmar, Kyi Htun

Applied Environmental Research

Myanmar is endowed with abundant natural and mineral resources. However, environmentaldegradation and social impacts have increased in recent years due to foreign investment in the mining sector and the application of modern technology in mining and processing methods to increase productivity. The growing trend towards new mining methods, particularly the shift from underground to open-cut method to mine and process low-grade ores contribute to generation of large volumes of waste rock and tailings, presenting a major disposal challenge. Wastes containing sulfides will further degrade the environment. Absence of an efficient legal framework for Artisanal and Small Scale Mining (ASM) for …

Mineral Resources Potential Of Vietnam And Current State Of Mining Activity, Nguyen Ngoc Khoi

Applied Environmental Research

Vietnam, with an area of 331,210 km2, occupies the eastern side of the Indochina peninsula. It forms a narrow (locally only 40-70 km)band of land, extending over 1,500 km along the East Sea (South China Sea). Vietnam is constituted mainly by the folded belts surrounding two shields, cratonised in the Upper Proterozoic: the Yangtze craton and the Indochina shield, located in the Mekongbasin and occupying most of Cambodia and the contiguous parts of Laos and Vietnam.

Environmental And Economic Of Flooring Building Materials, Nachawit Tikul

Applied Environmental Research

Green building design requires use of building materials that minimize environmental impact, necessitating selection of building materials by their environmental profile as well as economic cost-benefit considerations. The objective of this research is to determine the environmental impacts per square meter of three flooring materials; ceramic tiles, marble tiles, andparquet produced in Thailand. Life cycle cost (LCC) of the three materials are determined and compared. The study finds that ceramic tiles cause the greatest environmental impact, especially during the material extraction phase. When calculating all costsincurred throughout the life-cycle, the cost of untreated solid wood parquet is highest.

Incremental Concentration Of Black Carbon Aerosol From Road Traffic In Inner Bangkok, Panwadee Suwattiga

Applied Environmental Research

Commonly referred to as soot, black carbon (BC) is a primary aerosol emitted from incomplete combustion of organic materials such as fossil fuels, biofuels and biomass. BC aerosolis a dominant anthropogenic solar radiation absorber, absorbing approximately 1 million times more radiation per unit of mass than CO2. Recent research has found that BC is the second largest anthropogenic contributor to global warming. BC aerosol is not only a short-lived climate forcer (SLCF) but also an air pollutant that adversely affects human health. Emission sources of BC aerosol are mainly residential, industrial, transportation related and/or and open burning sources. In a …

Sustainable Mining In Thailand: Paradigm Shift In Environmental Management, Saneh Niyomthai, Annuwat Wattanawan

Applied Environmental Research

Thailand'smining industry has always been considered as an industrial activity generating significant environmental burdens. This is because environmental management in the sectorwas given lower prioritycompared with economic benefits. The resulting adverse environmental effects in areas surrounding some mining areas required government interventions.Accordingly, the sustainable development of mineral resources requires a delicate balance of economic, environmental and societal considerations. To respond to this challenge, Thailand needs a paradigm shift in environmental management towards sustainablemining, in order to maximize benefits from exploitation of the mineral resources,whilst ensuring co-existence and mutual benefits of mining activities and their surrounding communities.This article seeks to provide …

Ecology Collection

A photo-identification study on Risso’s dolphins was carried out off Bardsey Island in Wales (July to September, 1997-2007). Their local abundance was estimated using two different analytical techniques: 1) mark-recapture of well-marked dolphins using a “closed-population” model; and 2) a census technique based on the total number of iden-tified individual dolphins sighted over the study period. The mark-recapture estimates of 121 (left sides; 64 - 178, 95% CI; CV 0.24) and 145 dolphins (right sides; 78 - 213, 95% CI; CV 0.24) closely matched the census technique estimates (population size of 90 - 151). It was found that the dolphins …
