Coal Geology & Exploration
China is rich in high-rank coalbed methane(CBM) resources, which accounts for more than 90% of the total production of CBM in China. The efficient development and utilization of high-rank coal and coalbed methane(CBM) resources is of great practical significance for ensuring national energy strategic security and helping to achieve the strategic goals of “carbon peak and carbon neutrality”. The coalbed methane industry in China is generally characterized by low exploration and development degree, poor adaptability of main technology, low rate of return on investment and small development scale. The large-scale and efficient development of coalbed methane is faced with great …

Li-ion batteries (LIBs) are known to be one of the primary power sources for energy storage andconversion devices, including portable electronics and electric vehicles. State-of-the-art LIBsmanufacturing process is largely seeking advanced electrode production method with minimumenvironmental concern. Current manufacturing method is based on slurry casting process where atoxic solvent N-methyl pyrrolidone (NMP) is used. NMP is declared as a priority substance in USAunder the Toxic Substance Control Act (TSCA) for having “unreasonable risk” and requires immediateregulatory action. Thus, sustainable fabrication of slurry-based electrode involving greener alternativeof NMP is needed urgently to mitigate risks to both environment and workers. Likewise, wide …

Rapidly changing environmental and social conditions require thinking outside boxes and pioneering unconventional practices. But not just any innovative line of thought or novel practice will be a positive response to the major problems of our time; some might make things worse. How can we recognize unconventionality that orients us toward being more sustainable rather than less? One approach is to attend to complexity. Conventional thinking – that which is embedded throughout culture and is generally accepted – sees complexity as a characteristic of the world (earth systems are complex; society is complex) and as a problem to be simplified, …

The Design Of An Agricultural Youth-Centered Rural Development Program In Rwanda, Laetitia Igiraneza Sinyigenga
Honors Program: Senior Projects (Public)
Rwanda is primarily a rural, young, and agriculture-based country. The referred variables- agriculture, rural population, and youth- can be creatively merged to engage and empower youth for rural development. This paper indicates the utilization of cross-disciplinary knowledge to design an agricultural youth-centered rural development program in Rwanda. The program uses the interdependence of economic sectors (agriculture and education) with resources (environmental & natural resources and human resources) to boost rural community development. The program’s main activities- mentorship, agribusiness training, tutoring, exposure visits, and community work- highly reflect the requirement for advancing the selected main economic sectors and resources. There is …

Climate Change Adaptation, Migration, And Promising Developments For Pacific Island States, Ashley Jonas
Department of Environmental Studies: Undergraduate Student Theses
The people of the Pacific Islands face an existential crisis due to climate change, despite the fact that they are the least responsible for contributing to carbon emissions. The effects of climate change, namely sea-level rise, pose a verified threat to low-lying islands, infiltrating water supplies, crops, and infrastructure. As a result, there is a need for improved solutions for adapting to the impacts of climate change and for easier access to legal migration pathways when the consequences are insurmountable. Through comparative discourse analysis of scholarly sources, intergovernmental policies, and non-governmental organizations, the thesis finds that Small Island Developing States …

The societal impact of industrial pollution produced by economic activities is a global concern. This paper presents a causal analytic framework to evaluate the effectiveness of government policy on the reduction of industrial pollutants in 284 Chinese cities between 2005 and 2016. This study reports on the interaction between industrial pollution reduction and the level of regional economic development from four dimensions by using analysis of variance (ANOVA),multivariate analysis of variance (MANOVA) and a bootstrap autoregressive-distributed lag (ARDL) test. The results indicate that city government policies, economic power, the influence of megacities, and the geographical region of the cities have …

Agricultural Carbon Markets: How Could They Work?, Andrew Havens
Department of Environmental Studies: Undergraduate Student Theses
The resurgence of voluntary markets in which consumers can purchase carbon credits generated by agricultural carbon sequestration has brought up many questions for farmers looking to potentially enter the market. Past carbon markets, such as the Chicago Climate Exchange, ended when a recession hit, causing demand for credits to swiftly decline. How can modern voluntary markets face these challenges along with new ones and be successful? This research paper, completed as an undergraduate thesis project at the University of Nebraska-Lincoln, examines the economic and scientific factors behind soil carbon sequestration credits. An extended literature review combined with estimation of a …
