City Of Santa Fe's Offset Program: A Comprehensive Demand Analysis And Program Review, Francesca Shirley

Water Resources Professional Project Reports

In principle, Development Water Offset programs (offset programs) are designed to allow for urban growth without increasing water demand. Offset programs necessitate a reduction in existing water demand, typically achieved through plumbing retrofits, equal to the expected new demand, resulting in a net zero increase in water use. The City of Santa Fe (Santa Fe) has administered an offset program since 2002. The program banks water saved from its retrofit rebate programs. The banked water savings, known as Conservation Credits, can then be purchased by developers, and dedicated to new development projects. Under the water bank model, new demand has …

Oscars Vs. Ozone: The Motion Picture Industry’S Impact On Climate Change And What They Are Doing About It, Alexis J. Simpson

Senior Theses

This thesis focuses on demonstrating that the motion picture industry, which includes film and television production (and thus will also be called ‘the film and television industry’), has notably contributed to the global effects of climate change. Such contributions can stem from the industry’s emissions and waste, with examples including travel for cast and crew, energy use for production equipment (some of which run on diesel), and disposable physical sets and costumes. The intention here is to give an accurate picture of current production practices and share examples of progress in the industry that are combating the negative impacts of …

Lithium Extraction From Aqueous Solution Using Magnesium Doped Lithium Ion-Sieve Composite, Ujjwal Pokharel

Civil & Environmental Engineering Theses & Dissertations

This study focused on the development of a magnesium doped ion-sieve composite to extract lithium from an aqueous solution using adsorption process. The extraction process will provide a sustainable alternative to the currently practiced solar evaporation/concentration method which is very slow (takes 24 months) and water intensive. Currently, most of the lithium in the world comes from the mining of lithium or from the evaporative extraction process from the brine. Additionally, the Salton Sea area geothermal brines are recognized as potentially important domestic sources of lithium. Lithium concentration in geothermal brines from the Salton Sea area is reported to be …

Numerical Modelling Of Uniaxial Compressive Strength Laboratory Tests, Phu Minh Vuong Nguyen, Andrzej Walentek, Petr Waclawik, Kamil Soucek, Michał Antoniuk

Journal of Sustainable Mining

In the last decades, numerical modelling has been widely used to simulate rock mass behaviour in geo-engineering issues. The only disadvantage of numerical modelling is the reliability of required input data (e.g. mechanical parameters), which is not always fully provided due to the complexity of rock mass, project budget, available test methods or human errors. On the other hand, it was proven in many cases that numerical modelling is a helpful tool for solving such complex problems, especially when coupled with the results of laboratory and in-situ tests. This paper presents an attempt to determine the proper numerical constitutive model …

Self-Organization For Community Resilience In An Invisible Agricultural Community, Anna Erwin, Chelsea A. Silva, Zhao Ma

School of Earth, Environmental, & Marine Sciences Faculty Publications

This study investigates how self-organizing efforts by residents of informal settlements, primarily migrant and informal farmworkers, shape community resilience in Majes, a water-scarce irrigation district in the Atacama Desert of Peru. We collected 45 semi-structured interviews with residents and authorities in Majes and analyzed findings through a framework of self-organizing. Analyses revealed that self-organizing by residents of informal settlements incorporated the three components of White’s theory of Community Agency and Community Resilience, which contends that marginalized communities increase resilience by fostering a commons praxis, practicing a prefigurative politics, and developing opportunities for economic autonomy. We also found …
