Development Of A Framework To Support Community-Scale Nutrient Recovery For Local Crop Fertilization And Production, Scott A. Lopez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nutrient and resource recovery (NRR) has become increasingly crucial as regions face deteriorating sanitation infrastructures, limited support, and growing environmental challenges. Implementing region-specific NRR technologies and systems could provide effective circular economy insights into addressing these challenges. Because of the multidisciplinary challenges associated with the design and implementation of NRR strategies, various government and local decision-makers need to collaborate effectively in the decision-making process. Structured decision-making (SDM) methodologies are practical when determining the most appropriate NRR strategy for nutrient-rich waste streams. However, applications of computational SDM limited because of the vast amounts of data that are needed to analyze the …

Estimating Evapotranspiration And Analyzing Soil Moisture And Heat Flux Parameters At Taneum Creek, Central Washington, Edward Vlasenko

All Master's Theses

In the past two decades, stream restoration work, primarily in the form of wood emplacement, has been undertaken in the Taneum Creek watershed, resulting in increased channel-floodplain connectivity. One of the goals of stream restoration was to boost dry season groundwater storage in the shallow floodplain aquifer. However, any gains in groundwater due to increased connectivity may be nullified by increased evapotranspiration (ET) losses because of denser floodplain vegetation. Within the floodplain aquifer budget, ET is a major flow of water out of the system and is not well quantified.

In order to quantify ET, a monitoring site was established …

Middle Savannah River: An A/R/Tographic Ecopedagogical Ethnography Experimenting With Rhizomatic Perspectives, Lisa Augustine-Chizmar

College of Graduate Studies: Theses & Dissertations

This research is an experiment in perspective. Using the four commonplaces (Schwab, 1978), I practiced letting the Savannah River teach me what there is to know about the water, the land, the people, and the other entities that depend on ki through artistic, ethnographic, and ecopedagogical lenses. The ethnographic findings describe the social actors that depend on ki and give a voice to the River. The a/r/tographic findings display the River on a canvas map through two hundred years using paint, clay, photography, video, abstract acrylics, and fabric. Together, these methods contribute to a unique ecopedagogical journey. This word cloud …

Building The Soil And The Community At Hollands Track Farm, Newdegate, Western Australia, Jamie Bowyer, Nick Kelly

Natural resources published reports

The Kelly family have been farming at Hollands Track Farm, about 18 km south-west of Newdegate, since 1965. They currently produce grains, beef, eggs and sheep. Long-term annual average rainfall is 350 mm. The Kellys were early adopters – in the 1990s – of the no-till farming system, which is now widely used in Western Australia. Around 2002 they sold the last of their sheep and moved to a continuous cropping program with increased fertiliser and chemical use. They were very good at this system, and it served them well. They really enjoy the challenge of growing good crops. Over …

24/7 Clean Energy, Todd Aagaard

University of Colorado Law Review

In the face of the rapidly escalating climate crisis, the electricity sector is moving toward renewable energy. To date, policies and strategies have focused on increasing overall renewable energy generation, with little regard for timing and location. The result has been a misalignment of supply and demand in renewable energy markets. Renewable power projects produce energy when and where it is least expensive, leaving supply scarce at other times and places. Consumers, meanwhile, continue to use power when and where they need it. This mismatch increases the electricity grid’s dependence on fossil fuel–fired electricity to meet electricity demand at times …

Shallow Water Coral Distribution And Its Response To Climate Change, Amaury De Jesus

Dissertations and Theses

Shallow water corals are one of the main reef-building organisms that secrete carbonates as their skeletons, and therefore, are one of the major sinks of CO2 in the ocean. These reef builders are also very crucial to marine environments and human society. As the global energy demand continues rising, fossil fuel burning increases at a faster pace despite the increase in energy supply using clean and renewable energy. The increase of CO2 in the atmosphere has been shown to exacerbate global warming and may cause ocean acidification, threatening the habitat of shallow-water corals. Many recent observations show alarming signs of …
