Ecology And Christian Education: How Sustainability Discourse And Theological Anthropology Inform Teaching Methods, Chad Rimmer

Consensus

This paper will sketch theoretical synergies between sustainability discourse and a Christian ecotheological approach to religious education, and point to pedagogical possibilities for bridging the two disciplines. Theology and natural science operate with certain anthropological assumptions. Those underlying anthropologies inform the teaching methods of environmental and religious education. Anthropologies that conceive of human being outside of ecological relationships are a root problem of our current ecological crisis. Many economic, political and social discourses colonize people from the land, particularly children, exacerbating the root causes of sustainability. This paper affirms that linking sustainability discourse and religious education is a way to …

Sustainability And Climate In Religion: A Case Of Study Of The Green Churches Network In Africa (Toile Des Églises Vertes En Afrique) Teva, Marcel Ngirinshuti

Consensus

Faced with the ecological crisis, many churches are involved in the search for concrete solutions. Since 2016, the Green Churches Network in Africa (TEVA), a network of churches, denominational structures and associations, which are committed to caring for the "common home" (planet-earth) in Africa. This organization currently has (as of 2019) 1,808 parishes grouped into 19 churches in 12 African countries. The vision of TEVA is to reach 2020 green parishes by the end of 2020. Starting with the fact that ecological questions are often perceived as utopian and very complex, TEVA aims to promote knowledge of African ecological issues …

Women, Climate Change And Eco-Theology, Mary (Joy) Philip

Consensus

The impact of climate change is not proportionate to the ones that contribute to it. It is the world’s poorest and those in vulnerable situations, especially women and children, who bear the brunt of environmental, economic and social shocks. This paper highlights the fact that women are disproportionately affected by climate change, when they are primarily the ones that have been caring for and preserving the earth. This paper also argues for the need for eco-consciousness and the increased participation of women in climate initiatives, as women have a theology and spirituality undergirded by eco-consciousness.

La Habana: A History Of Society, Livelihood, Movement, And Land Use On The Iquitos-Nauta Highway, Katie Brown

Undergraduate Honors Theses

With increasing infrastructural projects and land titling in the Peruvian Amazon, many changes are occurring within small roadside communities. In this case study, we investigate how these changes impact livelihoods, land use, travel patterns, and social relations within the broader concepts of development, privatization of land, and commodification of nature. Specifically we focus on the caserío La Habana situated on the Iquitos-Nauta highway in the Loreto region of Peru. Semi-formal interviews and ethnographic methods were conducted to gather information on social organization, history of the community, land use practices, migration patterns, opinions on the road, and livelihood strategies. After data …

Effect Of Post-Consumer Content And Bioplastic Incorporation On Polymeric Resin In Consumer Applications, Shelby Bicknell

Electronic Theses & Dissertations

Controversy surrounds the use of plastic products, primarily due to their potentially negative impact on the environment at the end of their lifecycle. The most widely used plastics are manufactured from petrochemicals such as petroleum, coal or natural gas. Petrochemical plastics are not able to readily breakdown in the environment, which aggravates the existing pollution problems. Fortunately, there are eco-friendly alternatives to petrochemical-based plastics. Bioplastics may be derived from renewable sources, biodegradable, or both. Bio-based plastics are plastics that may be derived from renewable biomass sources including, but not limited to, vegetable oils, cornstarch, straw, woodchips, and food waste. They …

Low-Carbon Rebuilding Strategies For California Communities Impacted By Wildfires, Tessa Grezdo

Master's Projects and Capstones

In recent years, California’s wildfires have intensified and communities that have been impacted by these wildfires are now beginning to rebuild. Materials that are both fire-resistant and low in embodied carbon should be used when rebuilding in fire-prone regions. Embodied carbon in buildings contributes to about 11% of global greenhouse gas emissions. To help California reach its climate mitigation and resilience goals, this study examined the utilization of low-carbon and fire-resistant building materials during the post-wildfire rebuilding process. Embodied emissions are significantly reduced when building designs incorporate low-carbon materials. This study examined low-carbon and fire-resistant exterior building materials that can …

Energy Intensity Variation Among California Urban Water Supplies, Madeline Willett

Master's Projects and Capstones

Drought, population growth, and warmer temperatures will continue to strain and stress California's water supplies. Surface water and groundwater will not suffice as primary water supplies in the future. As California looks to build a more resilient water supply portfolio, the energy intensity of the water supplies in California could increase. This study examines 4 cities in California and their varied water supplies. Urban Water Management Plans (UWMP) are used to calculate the projected change in energy intensity of each city's supply. The results show that there is such variation in climate and water supply sources across California that there …

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle

Master's Projects and Capstones

Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an extent …

Bull Kelp (Nereocystic Lutkeana) Restoration And Management In Northern California, Olivia Johnson

Master's Projects and Capstones

Northern California’s coastal marine ecosystems support one of the most productive and biodiverse habitats on the planet. Bull kelp forests (Nereocystic lutkeana) form habitats for an abundance of marine mammals, sea bird, fish, and invertebrates. In recent years, compounding ecological and climatic factors have disrupted the balance of the bull kelp forests and led to an unprecedented loss of bull kelp biomass and canopy cover. These areas that are typically teeming with marine life have shifted into a stable state of sea urchin barrens due to over grazing of bull kelp by purple sea urchins (Strongylocentrotus pupuratus). These sea urchin …

A Review Of The Methods And Metrics In Research, Implementation, And Management Of Integrated Multi-Trophic Aquaculture, Cassandra Erickson

Master's Projects and Capstones

As seafood demand rises with the growing population, methods of providing sustainable and reliable protein are needed. Wild fishery stocks have decreased so aquaculture is seen as the way to meet these growing demands. The aquaculture industry has continued to grow 8.3% every year since 1970 primarily through using intensive cultivation of a single species creating negative effects on the marine environment. An increase in nutrients from these intensive cultivations can lead to eutrophication, a decrease in oxygen, and alter the ecosystem structure and biodiversity. Integrated multi-trophic aquaculture (IMTA) aims to offset the increased input of nutrients through fish farming …

Contrasting Storm Surge Barriers And Nature-Based Flood Mitigation For Port-Estuaries, Philip Orton

Sustainability Seminar Series

Deepwater port-estuaries have virtually no accepted and effective nature-based solution for sea level rise, because there is typically too little space for wetlands and deep shipping channels provide relatively friction-free pathways for floodwaters to reach neighborhoods. The Corps of Engineers is evaluating flood risk reduction strategies for the Port of New York and New Jersey and its estuarine waterways, with initial results pointing to gated storm surge barriers as the optimal solution. Jamaica Bay is one relatively unused port sub-estuary where a surge barrier is proposed, and I will demonstrate with computational modeling how a gradual “sedimentary restoration” over several …

The world-wide economic impact of global warming crises affecting trade, supply in products, availability of fossil fuels, and prices for goods and services makes moving towards renewable energy and sustainability more imperative than ever. Discussions and initial commitments to reduce global warming has been an important first step in creating a sustainable future; however, corporations now need enforceable policies and procedures to remain accountable.

Building Adaptive Capacity In Tribal Communities Of The Missouri River Basin To Manage Drought And Climate Extremes: A Case Study From The Wind River Indian Reservation, Crystal J. Stiles, Natalie Umphlett, Mitch Cottenoir

High Plains Regional Climate Center: Staff Publications

Native American peoples of the Northern and Central Plains have long endured harsh climate conditions, such as floods and droughts, and they possess valuable traditional knowledges that have enhanced their resilience to these extreme events. However, in recent times, limited capacity to adapt to a rapidly changing climate combined with a lack of resources have increased tribes’ vulnerability to climate extremes and their associated impacts. In response, a number of projects have been developed to assist tribes with their self-identified climate- and drought-related needs, particularly in the context of on-reservation decision-making. In this case study, we present an engagement strategy …

The Impact Of Extreme Heat On Environmental Justice Communities In California: Assessing Equity In Climate Action Plans, Karishma S. Becha

Master's Projects and Capstones

Climate change projections suggest extreme heat events will be more frequent over the next few decades. Extreme heat has both negative environmental and social impacts as it affects energy security, public health by increasing the risk of heat-related illnesses and stresses food and crop supply through prolonged droughts. The impacts of extreme heat will also disproportionately affect communities of low economic status. Because of this, there is a need for better climate action plans that can adapt to and mitigate the impacts brought upon by extreme heat that does not disproportionately impact vulnerable communities. This research analyzed local government Climate …
