Agenda: Evolving Regional Frameworks For Ag-To-Urban Water Transfers, University Of Colorado Boulder. Natural Resources Law Center, Western Water Policy Program, Western Water Assessment (Program), Red Lodge Clearinghouse

Evolving Regional Frameworks for Ag-to-Urban Water Transfers (December 11)

The permanent transfer of water from agricultural users to municipalities has become a common feature of water management in several western states. In many cases, these voluntary market‐based transfers provide significant benefits to both the buyers and sellers, but many third parties—including remaining irrigators, rural businesses and communities dependent upon agricultural economies—have been negatively impacted. While some impacts of these so‐called “buy and dry” transfers are largely unavoidable, many can be lessened by temporary arrangements that only shift water to cities in years when municipal supplies are inadequate, such as drought and post‐drought storage recovery, and by consolidating individual farm‐to‐city …

Environmental Evaluation Of A Quaternary Wastewater Treatment Wetland, Olivia Demeo, '09 Dec 2008

Environmental Evaluation Of A Quaternary Wastewater Treatment Wetland, Olivia Demeo, '09

Outstanding Senior Seminar Papers

Constructed wetlands for wastewater treatment have become a sustainable alternative to environmentally harmful traditional wastewater treatment methods. This case study evaluated the Schroeder Wildlife Sanctuary, a wetland area constructed for removal of nutrients from wastewater. An environmental evaluation of the wetland was completed that addressed three parameters: the water quality of wetland effluent, the avian biodiversity within the sanctuary, and an assessment of community outreach and education initiatives. Water quality testing was conducted using rudimentary LaMotte and Hach testing kits. The data was contrary to the literature and showed no nutrient removal occurring. However, the results were inconclusive because the …

Growing Food Justice In West Bloomington, Illinois, Daniel Burke, '09 Dec 2008

Growing Food Justice In West Bloomington, Illinois, Daniel Burke, '09

Outstanding Senior Seminar Papers

In some places in the United States, guns are more accessible than tomatoes. In a nation where food is in relative abundance, how can this be? Food security is the ready availability of nutritious and safe food and the assured ability to obtain it through normal sources (Morris et al 1992). Food justice asserts that no one should live without enough food because of economic constraints or social inequities. In this way, food justice frames the lack of healthy food sources in poor communities as a human rights issue (People's Grocery 2008). However, in some communities, access to fresh, healthy …


Integrating Landscapes That Have Experienced Rural Depopulation And Ecological Homogenization Into Tropical Conservation Planning, Aerin L. Jacob, Ismael Vaccaro, Raja Sengupta, Joel N. Hartter, Colin A. Chapman Dec 2008

Integrating Landscapes That Have Experienced Rural Depopulation And Ecological Homogenization Into Tropical Conservation Planning, Aerin L. Jacob, Ismael Vaccaro, Raja Sengupta, Joel N. Hartter, Colin A. Chapman

Geography

If current trends of declining fertility rates and increasing abandonment of rural land as a result of urbanization continue, this will signal a globally significant transformation with important consequences for policy makers interested in conservation planning. This transformation is presently evident in a number of countries and projections suggest it may occur in the future in many developing countries. We use rates of population growth and urbanization to project population trends in rural areas for 25 example countries. Our projections indicate a general decline in population density that has either occurred already (e.g., Mexico) or may occur in the future …


Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker Dec 2008

Water Quality Impacts From Agricultural Land-Use In The Karst Groundwater Basin Of Qingmuguan, Chongqing, China, Ted W. Baker

Masters Theses & Specialist Projects

Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, water resources are especially sensitive to contamination and pollution in karst areas. Pollutant concentrations going into fluvial systems travelling through the subsurface in karst areas are often very similar to the concentrations arriving at outlets such as springs. Areas connected by karst conduit flows must be distinctly determined and special attention should be …

Lifestyle Of Shellmound Builders In Brazil (Galley Proofs), Sabine Eggers, C. C. Petronilho, K. Brandt, J. Filippini, Karl J. Reinhard

School of Natural Resources: Faculty Publications

The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800–4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test …

Improving Beekeeping On Unguja Island, Larken Root Oct 2008

Improving Beekeeping On Unguja Island, Larken Root

Independent Study Project (ISP) Collection

The purpose of this study was to investigate the current practices and methods for improvement of beekeeping on Unguja Island in Zanzibar. Beekeeping has been occurring for many years in Unguja but has retained traditional techniques with little improvement. Improvement can occur in the form of introduction of modern equipment, formation of beekeeping organizations, advancing and diversifying products, and gaining governmental support. Beekeeping is worthy of expansion because of its potential to increase rural income in a sustainable way as well as support conservation of forest areas. The study found that there has so far been little improvement of income …

La Lucha Por Una Comunidad Sustentable Los Campesinos Tonocote De Breayoj: Manejo De Recursos, Desarrollo Y Elecciones, David Flannelly

Independent Study Project (ISP) Collection

A study about the environment and sustainability has to be soley about topics solely relating directly to nature, right? With this preconception in my mind I went off to study an indigenous subsistence farming community in the northwestern region of Argentina. Initially I solely wanted to focus on the management of resources of the community, the trees, water, and animals. Fate had other plans for my indepent study project. I arrived in the community right in the middle of the last week of historical elections for the province and the community. A new political party of farmers and other poor …

Defining A Fire Year For Reporting And Analysis Of Global Interannual Fire Variablility, Luigi Boschetti, David P. Roy Aug 2008

Defining A Fire Year For Reporting And Analysis Of Global Interannual Fire Variablility, Luigi Boschetti, David P. Roy

GSCE Faculty Publications

The interannual variability of fire activity has been studied without an explicit investigation of a suitable starting month for yearly calculations. Sensitivity analysis of 37 months of global MODIS active fire detections indicates that a 1-month change in the start of the fire year definition can lead, in the worst case, to a difference of over 6% and over 45% in global and subcontinental scale annual fire totals, respectively. Optimal starting months for analyses of global and subcontinental fire interannual variability are described. The research indicates that a fire year starting in March provides an optimal definition for annual global …


Plant Recruitment In A Northern Arizona Ponderosa Pine Forest: Testing Seed- And Leaf Litter- Limitation Hypotheses, Scott R. Abella Aug 2008

Plant Recruitment In A Northern Arizona Ponderosa Pine Forest: Testing Seed- And Leaf Litter- Limitation Hypotheses, Scott R. Abella

Public Policy and Leadership Faculty Publications

Seed availability and leaf litter limit plant establishment in some ecosystems. To evaluate the hypothesis that these factors limit understory plant recruitment in Pinus ponderosa forests, I conducted a seeding and litter removal experiment at six thinned sites in the Fort Valley Experimental Forest, northern Arizona. Experimental seeding of four native species (Penstemon virgatus, Erigeron formosissimus, Elymus elymoides, and Festuca arizonica) and raking of litter occurred in 2005. Seeding resulted in a substantial recruitment of 14 to 103 seedlings/m2 (1 to 10/ft2) one month after seeding for two species (P. virgatus and E. elymoides), but these densities subsequently declined by …

Numerical Analysis Of Non-Constant Pure Rate Of Time Preference: A Model Of Climate Policy, Tomoki Fujii, Larry Karp Jul 2008

Numerical Analysis Of Non-Constant Pure Rate Of Time Preference: A Model Of Climate Policy, Tomoki Fujii, Larry Karp

Research Collection School Of Economics

When current decisions affect welfare in the far-distant future, as with climate change, the use of a declining pure rate of time preference (PRTP) provides potentially important modeling flexibility. The difficulty of analyzing models with non-constant PRTP limits their application. We describe and provide software (available online) to implement an algorithm to numerically obtain a Markov perfect equilibrium for an optimal control problem with non-constant PRTP. We apply this software to a simplified version of the numerical climate change model used in the Stern Review. For our calibration, the policy recommendations are less sensitive to the PRTP than widely believed. …


Does The Corn/Soybean Farmer Have Time For Alternative Crops? [Abstract], Lori A. Hoagland, Laurie Hodges, Glenn A. Helmers, James R. Brandle, Charles A. Francis Jul 2008

Does The Corn/Soybean Farmer Have Time For Alternative Crops? [Abstract], Lori A. Hoagland, Laurie Hodges, Glenn A. Helmers, James R. Brandle, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Diversification of traditional row-crop farming in the Corn Belt is seen as advantageous in providing a wider economic base, decreasing economic risk associated with the link between commodity grain and cattle, increasing net farm income, and increasing biodiversity in the region. As farm size has increased to provide sufficient farm income, farm operations during the critical planting and harvesting windows are seen as limits to additional on-farm enterprises.
