Bulletin of Chinese Academy of Sciences (Chinese Version)

The carbon market serves as a crucial policy tool in the pursuit of carbon peaking and carbon neutrality goals. It holds significant importance in driving the innovation of green and low-carbon technologies in China, facilitating the realization of nationally determined contributions, and bolstering China’s global leadership in climate action. The core function of the carbon market is carbon pricing, which can only be effective and achieve various objectives like carbon emissions reduction and sustainable development when carbon costs are reasonably constrained. Environmental effectiveness, cost effectiveness, and incentive effectiveness are three important dimensions to evaluate the effectiveness of the carbon market, …

Natural Resource Factors Promoting Urban And Rural Integrated Development In The New Era: Target Selection And Policy Design, Zhimin Zhang, Guohua Yuan, Ruilin Liu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Reconstructing the reverse flood of natural resource elements in rural and urban regional systems is the basic form of requirement for realizing urban-rural integration. Taking target selection-realistic obstacles-institutional demand-system construction as the logical main line, starting from the current situation of natural resource element allocation under the framework of urban-rural integrated development, it sorted out the problems existing in the urban-rural integrated development of natural resources such as asymmetrical property rights design, inconsistent bearing plans of various types, lack of natural resource revenue sharing mechanism, and poor asset flow channels and trading systems, with unified layout, power return, paid use, …

Bulletin of Chinese Academy of Sciences (Chinese Version)

China is establishing a carbon budget management system at both provincial and municipal levels. The carbon budget system, as a policy tool for integrating total carbon emission management and economic planning, has already been effective in developed countries. This paper provides a comprehensive review of the concept, core elements, and practical experiences of the carbon budget system, and compares international practices with China’s low-carbon management system in the context of national circumstances. It extracts elements from international experiences that provide empirical insights, exhibit reference value, and require localization and innovation. Based on the analysis, this study proposes the following policy …

Sustainable Transportation: Transforming Utah Through Community Action, Isabella Erwin, Kendall Becker, Patrick A. Singleton, Scott Hotaling

All Current Publications

Transportation in the United States accounts for 4% of global greenhouse gas emissions. Over half of these emissions come from on-road vehicles. Nationwide, Utah has the third highest rate of car ownership, and the resulting air pollution from on-road vehicles has significant implications for the climate and public health. This fact sheet provides information on how Utah’s government and other entities are working to expand modes of transport that minimize harm to communities and the environment.

Estimating Post-Fire Flood Infrastructure Clogging And Overtopping Hazards, Ariane Jong-Levinger, Douglas Houston, Brett F. Sanders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Cycles of wildfire and rainfall produce sediment-laden floods that pose a hazard to development and may clog or overtop protective infrastructure, including debris basins and flood channels. The compound, post-fire flood hazards associated with infrastructure overtopping and clogging are challenging to estimate due to the need to account for interactions between sequences of wildfire and storm events and their impact on flood control infrastructure over time. Here we present data sources and calibration methods to estimate infrastructure clogging and channel overtopping hazards on a catchment-by-catchment basis using the Post-Fire Flood Hazard Model (PF2HazMo), a stochastic modeling approach that utilizes continuous …

Northern Fur Ssal Vibrissae Organochlorine Contaminant Concentrations, Dimitri Giarikos, Amy Hirons, Courtney White

SECLER Data

The eastern Pacific stock of northern fur seals (Callorhinus ursinus) on the Pribilof Islands has experienced population declines since 1980. The decline may be due to anthropogenic persistent organic pollutants (POPs) which bioaccumulate, are toxic, and persistent. This study conducted a comparison of 21 organochlorine (OC) and 39 polybrominated diphenyl ether (PBDE) analyte concentrations utilizing archived vibrissae (whiskers) from individual fur seals sampled in 1993 (n=30) and 2013 (n=41). The PBDEs had values five times greater than the legacy status OCs. There were no significant mean concentration differences between 1993 and 2013 for total organochlorines (ΣOCs), or total …

Groundwater Modeling Of The Ogallala Aquifer: Use Of Machine Learning For Model Parameterization And Sustainability Assessment, Tewodros Aboret Tilahun

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Addressing groundwater depletion problems in heterogeneous aquifer systems is a challenge. The heterogeneous Ogallala Aquifer, a critical source of groundwater in the central United States, has undergone decades of decline in water levels due to pumping. This project aims to build a robust groundwater model to evaluate optimal scenarios for sustainable use of the groundwater resource within a section of the Ogallala aquifer located in the Middle Republican Natural Resources District (MRNRD). This study follows a comprehensive approach involving parameterization, construction, and optimization. The model is parametrized using hydraulic conductivity and recharge values obtained from a random forest-based machine learning …

Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois

Electronic Theses and Dissertations

Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important topic to research as only a few long-term studies of Chinese tallow control have been conducted. A 10-year re-measurement of 22 paired plots installed in 2012 on the Pineywoods Mitigation Bank near Diboll, Texas following herbicide treatments examined Chinese tallow and native tree stand structure. Each …

Association Between Residential Distance To Airport And Blood Lead Levels In Children Under 6 Living In North Carolina, 1992–2015, Abdul-Nasah Soale

Faculty Scholarship

Even with progress in lead poisoning prevention, research has consistently shown there is no safe blood lead level (BLL) for children.1 Behavioral and cognitive deficits are associated with lead exposure, even at low levels.2 Unfortunately, many piston-engine aircraft are still fueled by leaded aviation gas (avgas). The US Environmental Protection Agency (EPA) estimates that 5.2 million people live within 500m of an airport where avgas is used.3 Our past research in six North Carolina (NC) counties indicates that children living within 500m of airports where avgas is used have ∼4% higher BLLs than children who lived beyond 2,000m (reference group); …
