Back To The Future – Pastoral Land Use In A Forest Land – Sustainability Challenges For The 21St Century, J. Morgan Williams
IGC Proceedings (1993-2023)
To contribute meaningfully to a session entitled “Deforestation” with a proposed paper title of “Trees in Pastoral Zones; Landuse Standards in the 21st Century” necessitates I carefully define the scope of my contribution. My paper will draw on my experiences as an ecologist working in the pastoral lands of New Zealand in roles that have led me to delve increasingly into what constitutes sustainability (of people, land and economy) for a tiny multicultural nation maturing amidst the remnants of a unique Gondwanaland ecosystem. As New Zealand’s Parliamentary Commissioner for the Environment (PCE) I now examine a very wide range …
The Effects Of Grazing Management And Fertilization On Grassland Diversity And Productivity, Warren Mcg. King, David R. Kemp
The Effects Of Grazing Management And Fertilization On Grassland Diversity And Productivity, Warren Mcg. King, David R. Kemp
IGC Proceedings (1993-2023)
The effects of management practices on plant species diversity and productivity within a naturalised grassland was studied as part of a large-scale experiment designed to investigate issues of sustainability in temperate Australia. Fertiliser increased the production but reduced the diversity of the sward. The main decline was in exotic weed species. Strategic grazing resulted in a small increase in pasture diversity but a reduction in productivity. There was a consistent decline in diversity as productivity increased, across all treatments.

IGC Proceedings (1993-2023)
The spatial pattern of vegetation in the following 3 semi-natural grasslands in Banska Bystrica, Slovakia, was observed in August, 1998: (1) a grassland sown with improved herbage plants after plowing in 1991, (2) a grassland oversown with improved herbage plants in 1991, and (3) a natural grassland without any treatment at the time of establishment. A new method of measuring vegetation was adopted: in each grassland, 50 quadrats 50 cm × 50 cm, composed of 4 smaller cells 25 cm × 25 cm, were set up, and all the species in each cell were recorded. The sown grassland displayed the …
Unbuilding: How Deconstruction Is Saving The Planet By Giving Building Materials A Second Life, Diana M. Ducroz
Unbuilding: How Deconstruction Is Saving The Planet By Giving Building Materials A Second Life, Diana M. Ducroz
Capstones
In 2018, more than 600 million tons of construction and demolition (C&D) waste was generated in the United States, more than twice the volume of ordinary trash created by American households and businesses. Even though 80-95% of this concrete, asphalt, steel, wood, drywall, glass and brick can be reused, repurposed or recycled, a quarter of it – or 145 million tons in 2018 – ends up in landfills. Thirty million tons of wood alone – often sturdy, irreplaceable old-growth lumber – is being trashed every year.
Now, a budding ‘build reuse’ movement, made up of environmentalists, architects, historic preservationists, city …
Electric Vehicle Integration In San Francisco, Lisa Farmos
Electric Vehicle Integration In San Francisco, Lisa Farmos
Master's Projects and Capstones
California’s Executive Order N-79-20 requires all new cars and passenger trucks sold in California to be zero-emissions by 2035. Electric vehicles (EVs) are the primary alternative fuel solution. However, there are widespread barriers to ownership, particularly for those in lower socioeconomic classes. A literature review of barriers to EV ownership shows the primary barrier is insufficient overnight charging infrastructure. Geospatial data of EV charging infrastructure and 2020 census tract data were used to map average income versus EV charging infrastructure in San Francisco. Data maps confirm the literature review findings: there is a positive correlation between income and EV charging …

IGC Proceedings (1993-2023)
The historical context, recent trends, and possible future role of forages in cropping systems are reviewed. Three recent themes will be developed: 1) The successful exploitation of genetic diversity resulting in commercial development of new legume species as pasture cultivars with specific traits better suited to the needs of current farming systems. 2) Improved understanding of key soil processes under grazed pastures, particularly soil water and soil nitrogen, and how these processes impact on indicators of sustainability like deep drainage and nitrate leaching. 3) An emerging capacity for predicting the effect of pasture-crop sequences on soil processes, crop growth and …
Land Use And Land Cover Change Impact On Sustainability In The United Arab Emirates: A Big-Data Approach Using Google Earth Engine, Wissam Atwah
Open Access Theses & Dissertations
The relevance of land use and land cover change (LULCC) impact on sustainability and well-being is increasing due to the urban growth challenges. LULCC data offers significant insight into the historic development patterns and their relations to various sustainability indicators. Different from the previous LULCC studies that merely focused on investigating LULCC problems in a small area (e.g., a city of an urban area) within a short span of time (e.g., a year), the current study intends to assess the long-term urbanization trend within a 20-year period for a whole country through the tracking of LULCC changes within the period. …
Solar Generated Electricity: An Analysis Of What Sectors Are Most Affected By Renewable Portfolio Standards And Related Policies, Logan Knollenberg
Solar Generated Electricity: An Analysis Of What Sectors Are Most Affected By Renewable Portfolio Standards And Related Policies, Logan Knollenberg
Dissertations and Theses
The aim of this thesis is to analyze state-specific Renewable Portfolio Standards (RPS) to understand their design and spillover effect onto non-utility (commercial, residential, industrial) sectors. Past research has overlooked non-utility sectors, often focusing on overall renewable energy growth and electricity generation from a combined end-result perspective. Solar capacity and solar generated electricity data from 5 states are used to establish which non-utility sectors experienced the highest level of solar growth from RPSs and related policies between 2010 and 2019. An explanatory sequential design is utilized, where interrupted time series analyses and exploratory case studies are performed to analyze each …
Theoretical Investigations Of The Structural, Dynamical, Electronic, Magnetic, And Thermoelectric Properties Of Corhysi (Y = Cr, Mn) Quaternary Heusler Alloys, Abdullah Hussain Hzzazi
Theoretical Investigations Of The Structural, Dynamical, Electronic, Magnetic, And Thermoelectric Properties Of Corhysi (Y = Cr, Mn) Quaternary Heusler Alloys, Abdullah Hussain Hzzazi
Graduate Theses and Dissertations
Thermoelectric materials have potential properties for utilizing waste heat. The computations are used to estimate the electronic structure of CoRhYSi (Y = Cr, Mn) Quaternary Heusler alloys, as well as their elastic and magnetic characteristics. The full-potential linearized augmented plane wave is used in the calculations. The exchange-correlations are addressed using Perdew–Burke and Ernzerhof's generalized gradient approximation (GGA-PBE). With the exception of CoRhCrSi and CoRhMnSi, which are simple ferromagnets that are approximately half metallic in nature, electronic structure calculations demonstrate that these compounds have a gap in the minority states band and are obviously half-metallic ferromagnets. The magnetic moments of …

A 60- Year Record Of The Demotechnic Index Of States, 1960-2019, Gavin James Kellough
A 60- Year Record Of The Demotechnic Index Of States, 1960-2019, Gavin James Kellough
Graduate Theses and Dissertations
A country’s dependency on energy resources can be interpreted through the calculation of energy indices. The Demotechnic Index (DI) was used to determine the trajectory of energy efficiency of each state in the United States over the period 1960-2019. The DI serves as a measure of the energy intensity of states and a proxy for energy sustainability of each state.The DI is the ratio of total energy use to total metabolic energy demand of a population. Mathematically, DI = (E_T-E_M)/E_M E_T represents the total energy used (metabolic energy + technological energy in kilojoules annually, kJ/y), while EM represents the basic …

Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern
Dissertations, Theses, and Capstone Projects
Coastal resiliency is becoming significantly more critical to the livelihood of coastal communities as the frequency and intensity of storm events increases and is exacerbated by rising sea levels due to climate change. In October 2012 Superstorm Sandy impacted the New York-New Jersey area costing over $70 billion in storm damages and 147 lives lost, as storm surges surpassed record highs for the region. Protruding more than 100 miles into the Atlantic Ocean with over 1,000 miles of shoreline, Long Island is particularly vulnerable to the increasingly ferocious and numerous storms as well as the rising sea levels that climate …

International Grassland Congress Outlook – A Historical Review And Future Expectations, L. R. Humphreys
International Grassland Congress Outlook – A Historical Review And Future Expectations, L. R. Humphreys
IGC Proceedings (1993-2023)
Features of the history of the International Grassland Congress are mentioned. Aspects of a number of failed themes in grassland science are described with respect to molecular biology, intensive systems of ruminant production, carbohydrate use in plant growth, plant succession and range condition, and stocking method. Future expectations are focused on meeting a balance of objectives, maintaining reductionist science, taking new initiatives in plant improvement and in the development of animal production systems, and reducing barriers to international trade. The adoption of grassland science depends upon the growth of new learning, especially through cyclical interaction between scientists and farmers.

Spatial Analysis Of Landscape Characteristics, Anthropogenic Factors, And Seasonality Effects On Water Quality In Portland, Oregon, Katherine Gelsey, Daniel Ramirez
REU Final Reports
Urban areas often struggle with deteriorated water quality as a result of complex interactions between landscape factors such as land cover, use, and management as well as climatic variables such as weather, precipitation, and atmospheric conditions. Green stormwater infrastructure (GSI) has been introduced as a strategy to reintroduce pre-development hydrological conditions in cities, but questions remain as to how GSI interacts with other landscape factors to affect water quality. We conducted a statistical analysis of six relevant water quality indicators in 131 water quality stations in four watersheds around Portland, Oregon using data from 2015 to 2021. Indiscriminate of station …

Diminishing Opportunities For Sustainability Of Coastal Cities In The Anthropocene: A Review, John W. Day, Joel D. Gunn, Joseph Robert Burger
Biology Faculty Publications
The world is urbanizing most rapidly in tropical to sub-temperate areas and in coastal zones. Climate change along with other global change forcings will diminish the opportunities for sustainability of cities, especially in coastal areas in low-income countries. Climate forcings include global temperature and heatwave increases that are expanding the equatorial tropical belt, sea-level rise, an increase in the frequency of the most intense tropical cyclones, both increases and decreases in freshwater inputs to coastal zones, and increasingly severe extreme precipitation events, droughts, freshwater shortages, heat waves, and wildfires. Current climate impacts are already strongly influencing natural and human systems. …

Towards Machine Learning-Based Demand Response Forecasting Using Smart Grid Data, Matthew S. Johnson
Theses, Dissertations and Culminating Projects
Demand response is a valuable tool for improving the reliability, stability, and financial efficiency of smart grids. With the intention of altering customer power consumption patterns, utility companies often implement strategies such as time-of-use (TOU) programs. Although effective in some situations, TOU programs struggle to perform in highly developed countries due to the complexity of human behavior. In this study, we analyze power consumption readings from smart meters from 5567 households in London, UK from November 2011 to February 2014 to measure the success of the TOU program. We additionally consider the variability of weather conditions and customer demographics when …
