A Multi-Country Assessment Of Factors Related To Smallholder Food Security In Varying Rainfall Conditions, Meredith T. Niles, Molly E. Brown
A Multi-Country Assessment Of Factors Related To Smallholder Food Security In Varying Rainfall Conditions, Meredith T. Niles, Molly E. Brown
College of Agriculture and Life Sciences Faculty Publications
Given that smallholder farmers are frequently food insecure and rely significantly on rain-fed agriculture, it is critical to examine climate variability and food insecurity. We utilize data from smallholder farmer surveys from 12 countries with 30 years of rainfall data to examine how rainfall variability and household resources are correlated with food security. We find that on average, households that experienced a drier than average year are 3.81 months food insecure, while households within a normal range of rainfall were 3.67 months food insecure, and wetter than average households were 2.86 months food insecure. Reduced odds of food insecurity is …
How Livestock Production In Eastern Nebraska May Affect Nitrate Concentrations In Platte River, Yuzhe Luo
How Livestock Production In Eastern Nebraska May Affect Nitrate Concentrations In Platte River, Yuzhe Luo
Department of Environmental Studies: Undergraduate Student Theses
The Platte River is one of the largest rivers in Nebraska and serves as a valuable water source to cities along its watershed. Water is essential for both human life and social and economic development. The human body cannot survive without water for more than 3 days, and many industries require water to function. At a regional scale, the total amount of water is relatively constant, which means if some water sources were contaminated there will be less water available to use.

Investigation Of Setting Time And Compressive Strength Of Ready-Mixed Concrete Blended With Returned Fresh Concrete, Negasi Niguse Gebremichael
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Center for Sustainable Transportation Infrastructure (CSTI), in its 2012 study, estimated that out of all the concrete leaving the plant, between 2% and 7% of concrete returns to the plant unused as a returned fresh concrete (RFC). Disposal of both the truck wash water and RFC is a growing concern for the industry. Most industry personnel contacted during the investigation, agree that reusing is superior to recycling of this substantial RFC economically and environmentally. This study will determine if the reuse of RFC in subsequent batches compromises the quality of newly blended concrete.
The effect of RFC on fresh …

Public sector leaders and decision makers in the California water industry have learned from previous severe drought conditions that to sustain water supplies during extremely dry seasons, there is a substantial need for behavioral changes associated with water conservation efforts among the businesses and residents of the community to maintain an adequate water supply. The intent of this study is to compare four California water agencies that have been designated as sustainable groundwater agencies (GSA), and determine what current programs and/or practices those agencies are using to meet the mandated requirements of the Sustainable Groundwater Management Act of 2014 (Act …

Identifying Worldviews On Corporate Sustainability: A Content Analysis Of Corporate Sustainability Reports, Nancy E. Landrum, Brian M. Ohsowski
School of Environmental Sustainability: Faculty Publications and Other Works
Companies commonly issue sustainability or corporate social responsibility (CSR) reports. This study seeks to understand worldviews of corporate sustainability, or the corporate message conveyed regarding what sustainability or CSR is and how to enact it. Content analysis of corporate sustainability reports is used to position each company report within stages of corporate sustainability. Results reveal that there are multiple coexisting worldviews of corporate sustainability, but the most dominant worldview is focused on the business case for sustainability, a position anchored in the weak sustainability paradigm. We contend that the business case and weak sustainability advanced in corporate sustainability reports and …

A Fix For A Thirsty World - Making Direct And Indirect Reuse Legally Possible, Heather Payne
William & Mary Environmental Law and Policy Review
Reliably providing safe drinking water to the public is an essential function of state and local governments. Across the United States, government officials and public water system managers are exploring mechanisms for ensuring water security. One method for increasing public drinking water security that has garnered the attention of water officials and the public is returning treated wastewater to the drinking water supply. However, in the absence of federal regulations on water reuse, states need guidance to develop the statutory framework necessary to make potable reuse legal. This Article details the processes of direct and indirect potable reuse and reviews …
Issues Related To Carbon Dioxide Pipeline Transportation Infrastructure In Louisiana, Michael Allen Layne Iii
Issues Related To Carbon Dioxide Pipeline Transportation Infrastructure In Louisiana, Michael Allen Layne Iii
LSU Master's Theses
There is no single solution to mitigate anthropogenic climate change; a multifaceted approach with economic incentives is needed. Carbon dioxide (CO2) enhanced oil recovery (EOR) is one such solution which provides an economic incentive, in the capture and sale of oil, for sequestering CO2 underground. While carbon capture and subsequent geological injection are both mature technologies, there has been little discussion or appreciation for the role of pipelines. The current CO2 pipeline infrastructure will need to significantly expand in order to accommodate increasing EOR production. However, pipeline construction costs, and institutional factors impacting development, may be …
Development, Energy, And Climate Change Policy: Enabling Sustainable Development Through Access To Energy, Robert J. Brecha
Development, Energy, And Climate Change Policy: Enabling Sustainable Development Through Access To Energy, Robert J. Brecha
Biennial Conference: The Social Practice of Human Rights
Human rights, human development, and climate change clearly overlap in many ways. Development, as quantified by the Human Development Index (HDI), for example, has historically been strongly correlated with energy consumption. This fact is recognized in Sustainable Development Goal (SDG) 7, to “ensure access to affordable, reliable, sustainable and modern energy for all.” Currently the world is in the midst of a large wave of human migration, much of it involuntary and due to stymied development opportunities as well as political upheaval. Climate change will become, or already is, an exacerbating factor in migration dynamics.
A pertinent question is how …
Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Journal on Empowering Teaching Excellence
Non-science, first year regional undergraduate students from rural Utah communities participated in an online introductory geology course and were asked to forecast the rise of CO2 in the Earth’s atmosphere. The majority of students predicted catastrophic rise to 5,000-ppm sometime over the next 3,100 years, resulting in an atmosphere nearly uninhabitable to human life. However, the level of concern the students exhibited in their answers was not directly proportional with their timing in their forecasted rise of CO2. This study showcases the importance of presenting students with actual data and using data to develop student forecasted models. …

The Complete Chloroplast Genome Of Primulina And Two Novel Strategies For Development Of High Polymorphic Loci For Population Genetic And Phylogenetic Studies, Chao Feng, Meizhen Xu, Chen Feng, Eric J.B. Von Wettberg, Ming Kang
College of Agriculture and Life Sciences Faculty Publications
Background: Primulina Hance is an emerging model for studying evolutionary divergence, adaptation and speciation of the karst flora. However, phylogenetic relationships within the genus have not been resolved due to low variation detected in the cpDNA regions. Chloroplast genomes can provide important information for phylogenetic and population genetic studies. Recent advances in next-generation sequencing (NGS) techniques greatly facilitate sequencing whole chloroplast genomes for multiple individuals. Consequently, novel strategies for development of highly polymorphic loci for population genetic and phylogenetic studies based on NGS data are needed. Methods: For development of high polymorphic loci for population genetic and phylogenetic studies, two …

At the beginning of the 20th century, over 40% by weight of all the materials consumed through the production of goods within the United States were comprised of renewable resources (Matos and Wagner 1998). In contrast, by the end of the 20th century renewable material usage had dropped to less than 8% by weight (Matos and Wagner 1998). Combined with both an increase in the overall rate at which we consume resources as well as growing awareness of the inherently finite availability of nonrenewable resources, the early decades of the 21st century may mark the beginning of a shift back …

Building Planner Commitment: Are California’S Sb 375 And Oregon’S Sb 1059 Models For Climate-Change Mitigation?, Keith Bartholomew, David Proffitt
TREC Final Reports
California’s Sustainable Communities and Climate Protection Act (SB 375) and the Oregon Sustainable Transportation Initiative (SB 1059) have made them the first states in the nation to try and reduce greenhouse gas (GHG) emissions using the transportation-planning process. Evaluating how these pioneering laws have changed local planning processes – as well as plans themselves – in each state provides insight into the laws’ effectiveness at changing development patterns in a way that reduces GHG emissions, without waiting decades to see the effects in the built environment. Both states’ laws require metropolitan planning organizations (MPOs) and the municipalities that comprise them …

Artizein: Arts and Teaching Journal
How can the teaching of biology contribute to sustainability education? The authors of this article suggest that their approach has the potential to increase the students’ level of engagement with the natural environment. The scope of biology teaching can be widened by allowing room for more experience and art-based activities. Such a change may deepen and expand the learners’ insights in natural phenomena, which in turn might foster or enhance an attitude of care-taking for the natural environment.

Arts-Based Education For Enchanting, Embodied And Embedded Sustainability, Hans Dieleman
Artizein: Arts and Teaching Journal
This article sketches two contrasting ideal-typical narratives of sustainability, a disenchanting and an enchanting one, and argues that current thinking in sustainability is mainly situated in the narrative of disenchantment. This narrative is based on various obsolete philosophical assumptions, and hampers the transformation process, as it distances the population from being part of this. It then sketches the narrative of enchanting sustainability and shows how this has the capacity to engage, intrigue and motivate people to be involved. It is rooted in an arts-based approach of connecting aesthetics, associative thinking, reflective practice, emotion-based working, aspiration and intentionality. The article moves …
Sustainability Of Community-Managed Rural Water Supply Systems In Amazonas, Peru: Assessing Monitoring Tools And External Support Provision, Jacob E. Mangum
Sustainability Of Community-Managed Rural Water Supply Systems In Amazonas, Peru: Assessing Monitoring Tools And External Support Provision, Jacob E. Mangum
USF Tampa Graduate Theses and Dissertations
Globally, there is still a large number of people without access to safe drinking water; a known health risk. In rural areas of countries like Peru, when potable water systems are built the responsibility for maintaining these systems is given to volunteer water committees. Despite its prevalence as a management model, there is a consensus that community management alone cannot ensure sustainable water service. Therefore, the overall goal of this research is to assess the sustainability of community-managed water systems in rural areas of the department of Amazonas, Peru. Specifically, this research examines two mechanisms that have been shown to …

Sustainability For Whom? Place-Makers Of Detroit, Dominica, Ecuador, And Mexico, Emma Gaalaas Mullaney
Sponsored Events -- List
Drawing from more than a decade of work with farmers in rural and urban areas across the Americas, Professor Gaalaas Mullaney highlights some key findings about how small-scale farmers have a big influence on the conservation of cultural and ecological richness in their region. In each of these diverse places, innovative farmers work at the margins of dominant political and economic institutions with only occasional recognition of the value that they produce. What can these farmers teach us about how to cultivate place-based sustainability? How is sustainability related to social and economic justice?

Although hardly noticed or formally recognized, urban foraging by humans probably occurs in all urban settings around the world. We draw from research in India, South Africa, Sweden, and the United States to demonstrate the ubiquity and varied nature of urban foraging in different contexts. Across these different contexts, we distill seven themes that characterize and thereby advance thinking about research and the understanding of urban foraging. We show that it is widespread and occurs across a variety of urban spaces and places. The species used and the local practices vary between contexts, and are in constant flux as urban …

Morphodynamics Of Atolls, Reef Flats, And The Islands Atop Them, Andrew Ashton
Morphodynamics Of Atolls, Reef Flats, And The Islands Atop Them, Andrew Ashton
Sustainability Seminar Series
The atolls that dot the tropical oceans of (primarily) the Pacific and Indian Oceans contain shallow and emergent coastal environments that often comprise the only subaerial, inhabitable land of many island chains and island nations. Created foremost by calcifying organisms, and composed of both biogenic rocky substrate and detrital sediment, these shallow environments are shaped by waves, currents, and tides. The low-lying, geomorphically active reef islands sitting atop of atolls face considerable hazards from climate change. I will present a series of recent and ongoing research projects addressing the formation mechanisms and potential climate change response of coastal atoll environments, …
