Communicating Nature-Society Relationships In Coastal Louisiana: An Evaluation Of The Ecosystem Services Framework, Vanessa Van Heerden

LSU Doctoral Dissertations

The ecosystem services (ES) framework is a tool to communicate the value of natural environments to human well-being by monetizing services that natural environments provide to humans. The Louisiana Coastal Master Plan uses the ecosystem services provided by the Mississippi River Delta as rationale for why coastal Louisiana should be protected. Here, I am interested in determining how the ecosystem services framework is used to communicate nature-society relationships in coastal Louisiana. I conducted a meta-analysis and spatial analysis to understand the spatial relationships of ecosystem services in the wetlands of coastal Louisiana. I then conducted a survey of residents of …

Shifting Sustainable Mobility Agendas In Graz (Austria) And Hangzhou (China): The Multi-Level Process From Livable To Smart Cities, Outi Luova

CSID Journal of Infrastructure Development

Several studies on various urban sustainability projects have observed their conceptual and technological similarity throughout the world but, at the same time, identified significant divergences in their actual local framing and implementation. By analysing sustainable mobility policies in Hangzhou (China) and Graz (Austria) and changes in their agendas during a period of thirty years, this article contributes to that discussion with new empirical insights. The development trajectories in Hangzhou and Graz will be compared to identify similarities and divergences and to suggest future paths for comparative studies in sustainable urban mobility. The study draws inspiration from multi-level governance theory and …

Investing In Nature Can Improve Equity And Economic Returns, Justin Andrew Johnson, Uris Baldos, Erwin Corong, Thomas Hertel, Stephen Polasky, Raffaello Cervigni, Toby Roxburgh, Giovanni Ruta, Colette Salemi, Sumil Thakrar

Department of Agricultural Economics Faculty Publications

Sustainable development requires jointly achieving economic development to raise standards of living and environmental sustainability to secure these gains for the long run. Here, we develop a local-to-global, and global-to-local, earth-economy model that integrates the Global Trade Analysis Project (GTAP)-computable general equilibrium model of the economy with the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model of fine-scale, spatially explicit ecosystem services. The integrated model, GTAP–InVEST, jointly determines land use, environmental conditions, ecosystem services, market prices, supply and demand across economic sectors, trade across regions, and aggregate performance metrics like GDP. We use the integrated model to analyze the …

Civil and Environmental Engineering Faculty Publications

Numerous strategies have been suggested to reduce dependence on synthetic products, such as physical, microbial, and natural methods. Among the natural remedies, plant extracts have emerged as a popular option owing to their eco-friendly character, ease of degradation, and harmless nature to humans. In our study, we used the acetone and hexane extracts of Rhaphiolepis indica fruit to combat two fungal pathogens that were isolated from infected bean plants and showed root rot symptoms. The two pathogens were confirmed to be pathogenic by pathogenicity assays conducted in vivo. The morphological and molecular identification by ITS-region sequencing revealed that the two …

Improving The Land Trust Model’S Impact On Environmental Conservation In Northern California, Peter Talbot

Master's Projects and Capstones

For years, the land trust sector of California and much of the United States has operated with a dollars and acres mentality that has prioritized fundraising as a result of acreage protected. Within California, nearly 5.8 million acres of land have been protected by 132 land trusts throughout the state. To accommodate for the diverse cross-section of land and the many needs of the population, land trusts take on numerous shapes and sizes. A unique aspect of this diversity is the rich agricultural and natural spaces found throughout the state. This mix of land and variety of land uses has …

Climate Change: The Ultimate Cereal Killer: The Impact Of Temperature And Precipitation On Agricultural Yields, Hayley Huber, Robert Salita, Ruth Abraham

Gettysburg College Headquarters

The global food supply depends on agricultural production, but as the negative effects of climate change are exacerbated by human activity, how will agriculture need to change to accommodate both climate change and the increasing population? In order to understand what adaptations will be necessary, we perform analysis on the relationship between climate change (temperature and precipitation) and crop yields (barley, rice, and soybean). We take a multinational approach, using ten countries for each model, to see the global impact of climate change on production. Testing many models, we settle on country-specific time trends, eliminating many confounding variables by focusing …

Climate Center Research (2021-2023)

Extreme heat is a serious issue that causes significant individual and collective health, safety, and economic costs. Some populations are more vulnerable to extreme heat, and extreme heat has an outsized impact on socially and politically marginalized populations such as low-income households and communities of color.

More Washingtonians will be vulnerable to extreme heat in the future due to the state’s aging population, urbanization, and climate change. Climate models project 4 to 6°F summer warming in the Pacific Northwest in the 2050s relative to the last half of the 20th century and the number of extreme heat days is projected …

An Integrated Analysis Of Urban Sustainability In Portland: Issues, Indicators, Stakeholders, And Geospatial Assessment, Arun Kumar Pallathadka

Dissertations and Theses

This dissertation presents three individual studies that collectively explore the concept of urban sustainability. The research is grounded in the recognition that many cities worldwide are striving to achieve sustainable development, yet existing sustainability frameworks often lack comprehensive definition and consideration. Moreover, the existing sustainability frameworks and methods are often not clearly structured to allow for their replication and adaptation to meet the unique needs of diverse local settings. To address this gap, the dissertation utilizes the Social-Ecological-Technological Framework, with particular emphasis on equity, to investigate key issues in urban sustainability, such as indicators, stakeholder engagement, tradeoffs, and assessment. The …

Liquid Border, Yingfan Jia

Masters Theses

A River is a mighty and constantly-evolving force, leaving behind an intricately designed and constantly changing system. Not just a river, the Rio Grande stretches all the way from Colorado before intersecting with the US-Mexico Border in southern Texas - a point where the powerful forces of nature now merge with a clearly-defined political boundary. The outcome of this is a unique ecological niche, which may often go unnoticed despite its distinctiveness.

Texas is famous for its farms and ranches, and the Rio Grande Valley of South Texas was once an agricultural hub. However, urbanization and the depletion of water …

Cohabitation X Adaptation, 2100: A Climate Change Epoch, Kyle Andrews

Masters Theses

Some seventy-seven odd years in the future, the world as we know it will only be recognizable by those who are willing to accept it. The bustling metropolis of Boston Massachusetts has been transformed to appease the tides of Mother Nature as a consequence of human intervention. In the decades prior, humanity viciously fought to contain the effects of climate change, until many realized the colossal undertaking of such a battle. Municipalities across the globe had begun to accept that fighting the earth was no longer an option. Instead, the only hope forward was to adapt to a reality in …
