Comprehensive And Agricultural Greenhouse Gas Emissions Inventories For Nebraska And The Midwest As Baselines For Climate Change Mitigation, Eric R. Holley
Comprehensive And Agricultural Greenhouse Gas Emissions Inventories For Nebraska And The Midwest As Baselines For Climate Change Mitigation, Eric R. Holley
School of Natural Resources: Dissertations, Theses, and Student Research
Climate change is the paramount challenge of today for a sustainable future. Mitigation of greenhouse gas (GHG) emissions is necessary to reduce the associated risks and impacts on society. Using the EPA’s SIT and literature review, comprehensive GHG-emissions inventories were developed for the state of Nebraska over 25 years (1990-2015) and agricultural GHG emissions inventories were developed for the Midwest U.S for one year (2016). Nebraska’s net emissions increased from 56.2 million metric tons of carbon dioxide equivalent (MMtCO2e) in 1990 to 87.4 MMtCO2e in 2016. Agriculture was found to be the sector with the most …

Widespread Severe Wildfires Under Climate Change Lead To Increased Forest Homogeneity In Dry Mixed-Conifer Forests, Brooke Alyce Cassell, Robert M. Scheller, Melissa S. Lucash, Matthew Hurteau, E. Louise Loudermilk
Widespread Severe Wildfires Under Climate Change Lead To Increased Forest Homogeneity In Dry Mixed-Conifer Forests, Brooke Alyce Cassell, Robert M. Scheller, Melissa S. Lucash, Matthew Hurteau, E. Louise Loudermilk
Environmental Science and Management Faculty Publications and Presentations
Climate warming in the western United States is causing changes to the wildfire regime in mixed-conifer forests. Rising temperatures, longer fire seasons, increased drought, as well as fire suppression and changes in land use, have led to greater and more severe wildfire activity, all contributing to altered forest composition over the past century. To understand future interactions among climate, wildfire, and vegetation in a fire-prone landscape in the southern Blue Mountains of central Oregon, we used a spatially explicit forest landscape model, LANDIS-II, to simulate forest and fire dynamics under current management practices and two projected climate scenarios. The results …

Psu Green Building Internship Final Report, 2019: Karl Miller Center Post-Occupancy Study, Everett Stilley, Junyoung Lee
Campus Sustainability Office Publications, Reports and Presentations
This study examined the effectiveness of the passive cooling strategies in the Karl Miller Center (KMC) at Portland State University. Due to the warm temperatures reached in Portland during the summer months and the absence of a mechanical cooling system on the Pavilion side of the KMC, classrooms can exceed thermal comfort preferences on a number of occasions. Previous studies have recommended taking certain classrooms “offline” after 12pm in the summer, where they are only available for morning classes. This study aimed to update the classroom prioritization as well as analyze the employed cooling strategies and begin a long term …

Mountain lakes are often situated in protected natural areas, a feature that leads to their role as sentinels of global environmental change. Despite variations in latitude, mountain lakes share many features, including their location in catchments with steep topographic gradients, cold temperatures, high incident solar and ultraviolet radiation (UVR), and prolonged ice and snow cover. These characteristics, in turn, affect mountain lake ecosystem structure, diversity, and productivity. The lakes themselves are mostly small and shallow, and up until recently, have been characterized as oligotrophic. This paper provides a review and update of the growing body of research that shows that …

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the …

This report provides Portland State University’s (PSU) Campus Sustainability Office (CSO), with an objective third party LEED O+M Materials Assessment of PSU’s University Services Building (USB). The data collected for this audit provides CSO with insight into the building’s current waste composition and diversion rate. Additionally, it identifies opportunities to reduce the amount of recoverable materials ending up in the landfill stream. Community Environmental Services (CES) conducted material audits for 100% of USB’s landfill-bound, commingled recycling, and compost streams during a 24-hour period. While, audited construction and demolition (C&D) materials were generated over the course of a week.

Climate-driven increases in wildfires, drought conditions, and insect outbreaks are critical threats to forest carbon stores. In particular, bark beetles are important disturbance agents although their long-term interactions with future climate change are poorly understood. Droughts and the associated moisture deficit contribute to the onset of bark beetle outbreaks although outbreak extent and severity is dependent upon the density of host trees, wildfire, and forest management. Our objective was to estimate the effects of climate change and bark beetle outbreaks on ecosystem carbon dynamics over the next century in a western US forest. Specifically, we hypothesized that (a) bark beetle …

Parkmill’s Design, Construction, and Mechanical Systems
The Parkmill building is located on the lower south section of Portland State University’s (PSU) urban campus between SW Park Avenue and SW Mill Street.The lot space, originally selected for the design proposal in 1956, was located between two buildings including the acquired Parkway Manor (currently designated as PSU housing) and former frame house-type buildings. The proposed building would supplement the evening and summer curriculum courses offered by the General Education Division (GED) in partnership with Portland State College and would become a vital resource for students in the Portland metropolitan area.

Portland State University (PSU) serves as a Landlord to over 60 third-party tenants, including retail, food service, office, food cart, and other tenant types. To encourage and standardize the adoption and practice of sustainability behaviors among these tenants, PSU hired a Green Leasing Intern during the summer of 2017. The intern, graduate student Emily Quinton, managed by members of the PSU Planning, Construction & Real Estate (PCRE) team, was tasked with researching best practices, drafting green leasing language, and developing tenant engagement and incentive-based approaches to implementation. This report serves as the culminating deliverable for that internship. Additional internship documentation …

Forests around the world are experiencing increasingly severe droughts and elevated competitive intensity due to increased tree density. However, the influence of interactions between drought and competition on forest growth remains poorly understood. Using a unique dataset of stand-scale dendrochronology sampled from 6405 trees, we quantified how annual growth of entire tree populations responds to drought and competition in eight, long-term (multi-decadal), experiments with replicated levels of density (e.g., competitive intensity) arrayed across a broad climatic and compositional gradient. Forest growth (cumulative individual tree growth within a stand) declined during drought, especially during more severe drought in drier climates. Forest …

Geography Faculty Publications and Presentations
This study analyzed watershed response to climate change and forest fire impacts in the upper Umatilla River Basin (URB), Oregon, using the precipitation runoff modeling system. Ten global climate models using Coupled Intercomparison Project Phase 5 experiments with Representative Concentration Pathways (RCP) 4.5 and 8.5 were used to simulate the effects of climate and fire-burns on runoff behavior throughout the 21st century. We observed the center timing (CT) of flow, seasonal flows, snow water equivalent (SWE) and basin recharge. In the upper URB, hydrologic regime shifts from a snow-rain-dominated to rain-dominated basin. Ensemble mean CT occurs 27 days earlier in …
