Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson

Public Administration Faculty Publications and Presentations

This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

Calvin University has committed to being carbon neutral by 2057. This entails removing all the natural gas consumption for heating, converting to electrical heating options, and then making carbon free electricity. This project looked into four different options: air source heat pumps, ground source heat pumps, renewable natural gas, and the efficiency of current equipment. Each option was examined throughout the course of the semester to determine feasibility of each solution, and which ones would be best to implement. As a class, section A decided ground source heat pumps along with thermostatic valves and the implementation of double pane windows …

Eat Your Invasives: A Practical And Historical Analysis Of Foraging For Invasive Foods, Grace Hartman

Honors Projects

This paper discusses both the historical and modern role of foraging and why people may decide to forage, as well as barriers new foragers may face and how they can be overcome. Furthermore, the paper discusses how foraging for invasive species can be used as a method of conservation and how simple foraging can be encouraged for this reason.

Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the carbon balance of tundra ecosystems. In this study, we address some of these uncertainties through a novel record of 119 site-years of summer data from eddy covariance towers representing dominant tundra vegetation types located on continuous permafrost in the Arctic. Here we found that earlier snowmelt was associated with more tundra net CO2 sequestration and higher gross primary productivity (GPP) only in June …

What Technologies And Barriers Are Present In Sustainable Heating And Cooling, Mason D. Nibbe

Environmental Studies Student Work

Sustainable heating and cooling practices can save homeowners money and reduce their carbon emissions. In the cold upper Midwest, Minnesota specifically, there are ways houses can be more efficient in terms of heating. The most efficient and practical are heat pumps systems, passive solar designs, and proper insulation of the building. This study is targeted at both existing buildings and the construction of new buildings. This project focuses on what sustainable heating and cooling practices, technologies, and barriers are present in the heating, ventilation, and air-conditioning (HVAC) industry.

Transportation Asset Management For The Electric Road System, Kamalen Maria Santos Diaz

Open Access Theses & Dissertations

Electric road systems (ERS) have been presented as a new solution towards a sustainable transportation future, fueling the widespread adoption of electric vehicles by eliminating range anxiety, reducing battery size, and being regional friendly. These systems consist of four components: electric power supply, roads, vehicles, and operations. Much of the early research conducted on ERS has been on how to initially construct these systems by focusing on the first three components, however, there is limited knowledge on how ERS will impact traditional road operations after the systems are in place. Transportation Asset Management (TAM), a major focus within the transportation …

Identifying How Summer Camp Experiences Affect Children’S Environmental Literacy, Quinn Kimbell

Department of Environmental Studies: Undergraduate Student Theses

Ensuring that children are prepared for environmental issues in the future can be aided by building the skill of environmental literacy. A key factor in building this skill is having natural experiences and creating one’s connection and perception of the environment. This paper aims to identify if summer camps increase children’s perception of the environment. This was completed by testing children with an environmental perception survey (Children’s Environmental Perception Scale) before and after attending a summer camp and assessing environmental pollution knowledge through drawing (modified Draw-An-Environment Test). The rural Nebraska summer camp subjected the children to many outdoor experiences, including …

Sustainability is a multi-faceted grand challenge. One of today’s largest challenges is related to sustainability: CO2 emissions from energy consumption. Calvin University purchases natural gas for the energy services it provides; however, it is a major contributor to the amount of CO2 emitted into the atmosphere. The ENGR 333 section B class was tasked with the question: What would it take to eliminate Calvin’s natural gas-related net CO2 emissions? After many hours of research and calculations, the ENGR 333 section B class answered this question with recommendations such as implementing ground source heat pumps, console heat pumps, air source heat …

Using Landsat Satellite Imagery To Estimate Groundcover In The Grainbelt Of Western Australia, Justin Laycock, Nick Middleton, Karen Holmes

Resource management technical reports

Maintaining vegetative groundcover is an important component of sustainable agricultural systems and plays a critical function for soil and land conservation in Western Australia’s (WA) grainbelt (the south-west cropping region). This report describes how satellite imagery can be used to quantitatively and objectively estimate total vegetative groundcover, both in near real time and historically across large areas. We used the Landsat seasonal fractional groundcover products developed by the Joint Remote Sensing Research Program from the extensive archive of Landsat imagery. These products provide an estimate of the percentage of green vegetation, non-green vegetation and bare soil for each 30 m …

Microplastic Accumulation In Terrestrial Gastropods And Soils, Gregory B. Bonilla

Masters Theses

Microplastics (MPs) have become an emerging threat to ecosystems across the world. Transport, impacts, and fates are grossly understudied, especially in terrestrial environments. Current research on MP bioaccumulation has focused mainly on aquatic organisms with little study of terrestrial organisms, including snails where data are nearly nonexistent. To address this, we collected and examined land snails and their surrounding soil for MP content in shell and tissue. From September 11, 2020, to October 25, 2021, cover boards were placed (n=30) along relatively undisturbed sites in hardwood, forested areas, and tall grasses in a Wildlife Management Area (WMA) in Oak Ridge …

Conflicts Between Ghg Accounting Methodologies In The Steel Industry, John Biberman, Perrine Toledano, Baihui Lei, Max Lulavy, Rohini Ram Mohan

Columbia Center on Sustainable Investment

Accurate, verifiable, and comparable greenhouse gas (GHG) emissions data throughout supply chains in the materials sector are necessary to drive decarbonization. This is particularly the case for the steel supply chain, a major source of GHG emissions with untapped potential for reduction. However, emissions accounting methods used by the steel industry suffer from gaps and misalignment, resulting in significant differences in reported GHG emissions. The result is a patchwork reporting landscape vulnerable to manipulation and miscommunication, generating little actionable data for policymakers, producers, customers, and investors. These shortcomings highlight the need for a harmonized carbon accounting framework for the steel …
