Groundwater Banking In Imperial Irrigation District: Planning For Future Water Scarcity On The Colorado River, Sara Morton May 2015

Groundwater Banking In Imperial Irrigation District: Planning For Future Water Scarcity On The Colorado River, Sara Morton

Master's Projects and Capstones

Urban and rural economies throughout the southwestern United States and Mexico rely on surface water imported from the Colorado River. The Imperial Irrigation District (herein IID or District) has rights to use 3.1 million acre-feet (MAF) per year of Colorado River Water (Regional Water Management Group 2013 and Imperial Irrigation District 2009). Of this water entitlement, IID uses 97 percent for agricultural production. In addition, IID supplies water to San Diego and Los Angeles urban areas.

The population reliant on Colorado River water is expected to rise from approximately 40 million people today, up to 76 million people over the …

Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera

Master's Projects and Capstones

Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …

Urban Scale Modeling Of Atmospheric Carbon Dioxide And Validation Of Emission Inventories, James E. Powell, Christopher L. Butenhoff, Andrew L. Rice May 2015

Urban Scale Modeling Of Atmospheric Carbon Dioxide And Validation Of Emission Inventories, James E. Powell, Christopher L. Butenhoff, Andrew L. Rice

Student Research Symposium

There exists a pressing need for high resolution emissions inventories for cities. For greenhouse gases, cities and regions need a careful analysis of their carbon footprint to design effective policies to control and mitigate emissions. High resolution emissions inventories can be used in conjunction with meteorology models and atmospheric measurements to place top-down constraints on emissions. High resolution emissions inventories for criteria pollutants like NOx, CO, and O3 enable urban-scale air pollution modeling down to the neighborhood level. For example, the Vulcan project estimates CO2 using county-scale vehicle miles traveled (VMT) from the National Mobile Inventory …

Genetic And Morphological Variation In Ecuadorian Astroblepid Catfishes, Katherine M. Lawry May 2015

Genetic And Morphological Variation In Ecuadorian Astroblepid Catfishes, Katherine M. Lawry

School of Natural Resources: Dissertations, Theses, and Student Research

The Andean ichthyofauna remains a poorly understood component of Neotropical biodiversity, and stands in stark contrast to the lowland ichthyofauna in terms of number of species and range of distribution. The Climate Variability Hypothesis (CVH) predicts rapid turnover of species along elevational gradients in tropical climates, but it remains unclear whether stream fishes follow this pattern. Astroblepid catfishes represent a distinctive assemblage of species that inhabit high elevation streams throughout the Andes from Panama to Bolivia, and constitute the only native fish family present in the Ecuadorian highland region. In this research, population samples of Astroblepids collected throughout Ecuador’s Napo …


Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie May 2015

Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie

School of Natural Resources: Dissertations, Theses, and Student Research

Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered the wetland landscape in both …

Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel Apr 2015

Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This dissertation consists of three essays. The first essay examines the impact of the 2012 drought and the biofuels mandate on the U.S. grain and livestock markets. A stochastic equilibrium displacement model is used to analyze the impact on eight commodity markets viz. beef, pork, poultry, corn, distillers’ grain (DG), soybean, soymeal, and ethanol. Among the eight markets, corn and beef are found to be the most vulnerable to drought. The use of Renewable Identification Number (RIN) credits as an instrument to mitigate the impact of drought has limited effectiveness. A mandate waiver of about 23% is required to fully …

Comparison Of Fish Assemblages In Restored And Natural Mangrove Habitats Along An Urban Shoreline, Joseph R. Peters, Lauren A. Yeager, Craig A. Layman Apr 2015

Comparison Of Fish Assemblages In Restored And Natural Mangrove Habitats Along An Urban Shoreline, Joseph R. Peters, Lauren A. Yeager, Craig A. Layman

Environmental Science and Management Faculty Publications and Presentations

The installation of living shorelines is one strategy used to ameliorate habitat degradation along developed coastlines. In this process, existing hard structures, such as sea walls and riprap revetments, are supplemented with habitat forming species, e.g., oysters and mangrove trees, to improve habitat quality and function. Shoreline restorations in Biscayne Bay, Florida, USA, often utilize red mangroves, Rhizophora mangle (Linneaus, 1753), in addition to riprap revetments, to help stabilize the shoreline. This riprap-mangrove habitat provides structure for marine organisms to utilize and is believed to improve shoreline habitats in areas previously cleared of mangroves. We examined whether habitat provisioning was …

Verifying national greenhouse gas (GHG) emissions inventories is a critical step to ensure that reported emissions data to the United Nations Framework Convention on Climate Change (UNFCCC) are accurate and representative of a country's contribution to GHG concentrations in the atmosphere. Furthermore, verifying biogenic fluxes provides a check on estimated emissions associated with managing lands for carbon sequestration and other activities, which often have large uncertainties. We report here on the challenges and results associated with a case study using atmospheric measurements of CO₂ concentrations and inverse modeling to verify nationally-reported biogenic CO₂ emissions. The biogenic CO₂ emissions inventory was …
