Essays On Common-Pool Resources: Evaluation Of Water Management And Conservation Programs, Kuatbay K. Bektemirov

Graduate Theses and Dissertations

This dissertation is comprised of three essays that examine water management and conservation programs through the context of sustainable development. These essays are distinct case studies of national, state and local policies. Their common approach is that they all use common-pool resources theory to generate specific recommendations for policymaking and water management.

The first essay explores opportunities for developing policy measures to prevent the collapse of the vital irrigation infrastructure in the Aral Sea region. The paper looks at the economic efficiency of various policy options, impacts on the country’s agricultural sector, and the regulations needed to make the cost-sharing …

In just the past 5 years, the field of Earth observation has progressed beyond the offerings of conventional space-agency-based platforms to include a plethora of sensing opportunities afforded by CubeSats, unmanned aerial vehicles (UAVs), and smartphone technologies that are being embraced by both for-profit companies and individual researchers. Over the previous decades, space agency efforts have brought forth well-known and immensely useful satellites such as the Landsat series and the Gravity Research and Climate Experiment (GRACE) system, with costs typically of the order of 1 billion dollars per satellite and with concept-to-launch timelines of the order of 2 decades (for …

Habitat Management For Northern Bobwhites In Wisconsin: A Long-Term Assessment, Leroy R. Petersen, Robert T. Dumke, Barbara F. Duerksen

National Quail Symposium Proceedings

An experimental habitat management program was initiated to improve the carrying capacity for northern bobwhites ( Colinus virginianus) on private lands by the Wisconsin Department of Natural Resources (WDNR) in 1974. During 1975-80, extensive habitat restoration was undertaken on a 60-mi2 (l55-km 2) study area in Richland County to restore hedge row cover, improve riparian corridors and woodlot edges, and construct plots of food and shelter to function as wintering sites for bobwhites. Previous investigations in Wisconsin have documented that the long-term decline of bobwhites was the result of habitat deterioration, principally hedgerow cover. Elsewhere, continuous declines in bobwhite abundance …

Consequences Of Severe Habitat Fragmentation On Density, Genetics, And Spatial Capture-Recapture Analysis Of A Small Bear Population, Sean Mccarthy Murphy, Ben C. Augustine, Wade Allen Ulrey, Joseph Maddox Guthrie, Brian K Scheick, J. Walter Mccown, John J. Cox

Forestry and Natural Resources Faculty Publications

Loss and fragmentation of natural habitats caused by human land uses have subdivided several formerly contiguous large carnivore populations into multiple small and often isolated subpopulations, which can reduce genetic variation and lead to precipitous population declines. Substantial habitat loss and fragmentation from urban development and agriculture expansion relegated the Highlands-Glades subpopulation (HGS) of Florida, USA, black bears (Ursus americanus floridanus) to prolonged isolation; increasing human land development is projected to cause ≥ 50% loss of remaining natural habitats occupied by the HGS in coming decades. We conducted a noninvasive genetic spatial capture-recapture study to quantitatively describe the …

Scaling, Similarity, And The Fourth Paradigm For Hydrology, Chirsta D. Peters-Lidard, Martyn Clark, Luis Samaniego, Niko E. C. Verhoest, Tim Van Emmerik, Remko Uijlenhoet, Kevin Achieng, Trenton E. Franz, Ross Woods

School of Natural Resources: Faculty Publications

In this synthesis paper addressing hydrologic scaling and similarity, we posit that roadblocks in the search for universal laws of hydrology are hindered by our focus on computational simulation (the third paradigm) and assert that it is time for hydrology to embrace a fourth paradigm of data intensive science. Advances in information-based hydrologic science, coupled with an explosion of hydrologic data and advances in parameter estimation and modeling, have laid the foundation for a data-driven framework for scrutinizing hydrological scaling and similarity hypotheses. We summarize important scaling and similarity concepts (hypotheses) that require testing; describe a mutual information framework for …

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This paper seeks to figure out the effect weather has on individuals’ behavior. A more focused approach to determining this effect is seeing how different weather conditions ranging from the temperature, the precipitation, the amount of inches of snowfall and the wind speed effect the ridership of Citi Bikes throughout all four seasons. The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi …

Electricity Demand Due To Policy Change In The U.K., Kevin W. Doherty

Journal of Environmental and Resource Economics at Colby

This paper examines United Kingdom Electricity Demand with regards to the Climate Change Act, which was enacted in November of 2008. Through actual demand data obtained from Nationalgrid, a U.K. based gas and electric utility company, this paper seeks to find out if the Climate Change Act has started to achieve its goal of reducing carbon emissions by looking at trends of electricity demand. Burning fossil fuels to produce electricity is a major contributor to global warming in the U.K. and policies enacted do not always live up to their ultimate goals. This paper tests how on track the Climate …

The Demographic Drivers Of California’S Environmental Voting, Lukas Yasuda

Journal of Environmental and Resource Economics at Colby

This study examines the demographics of California’s 53 congressional districts and the relationship with the voting patterns on three environmentally focused propositions in the 2008 and 2010 elections. Previous literature on the topic is mixed as some studies suggest that select attributes are found among environmental voting centers, yet other research describes the relationship as more complex than simple characteristics. Previous literature on the topic is mixed, with some studies suggesting that select attributes are found among environmental vote support hubs, whereas alternative research suggests the problem is more complex than simple characteristics. I collected data on income, education, age, …

How Individuals React To Smog Alerts In Beijing --Evidence From Beijing Subway Volume, Hanjing Shi

Journal of Environmental and Resource Economics at Colby

This paper is going to find out the impact of smog alerts on individuals’ outdoor activities in Beijing. I use the subway volume to represent the outdoor activities. There are four levels of smog alerts in Beijing – blue, yellow, orange, and, red. The blue one is the lowest, and the red one is the highest. People in Beijing in all do not react to smog alerts in all statistically significant both on working days and weekends. But when combine orange alerts and red alerts together, the results show that people react to severe alerts differently during non-weekend days and …

Nudging Neighbors: Analyzing Peer Effects Of The Lakesmart Program In The Belgrade Lakes, George A. Voigt

Journal of Environmental and Resource Economics at Colby

Peer effects are an increasingly studied field in economics, and can have large impacts at a local level. In this research we seek to identify whether there is an impact of early adopters on their neighbors to become adopters. The scope for this study is the LakeSmart program that operate in Maine. Specifically we are focusing on the Belgrade lakes, and analyzing data from 2005 to present in addition with a survey of demographic characteristics conducted in 2011. Results suggest that the impact of a neighbor on the likelihood of a household to be LakeSmart certified is statistically significant and …

Water Restrictions And Water Use: An Analysis Of Water Restriction Effects In Norfolk County, Rebecca L. Robinson, Ashley Conley

Journal of Environmental and Resource Economics at Colby

This paper aims to determine what effect water restrictions in Norfolk County, Massachusetts have on residential water usage. Using data from the Massachusetts Department of Environmental Protection, this paper analyzes subsequent municipal water usage within and across towns after water restrictions, both mandatory and voluntary, are implemented. Accounting for town fixed effects, the results indicate that for some towns, water restrictions do in fact have a significant impact on decreasing water usage.

The Epa's Air Quality Index, And Public Transportation Usage In The Chicago Metro Region, Nicholas R. Rosenberg

Journal of Environmental and Resource Economics at Colby

This paper assesses whether air quality influences public transportation ridership in the city of Chicago. Urban air pollution is a serious health risk, and a priority of urban municipalities. Public transportation is an attractive option for governments attempting to curb urban air emissions. I use data from the Chicago Transit Authority (CTA) and the EPA’s Air Quality Index (AQI) to explore the relationship between a day’s air quality and CTA ridership. I employ three different model specifications, rail, bus and total ridership, to test whether high AQI values (poor air quality) result in increased public transportation ridership in the city …

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

When Trash Costs Money: Analyzing The Impact Of Pay-As-You-Throw Programs In Massachusetts, Thomas W. Barry Iv

Journal of Environmental and Resource Economics at Colby

This paper evaluates whether municipalities with Pay-As-You-Throw (PAYT) programs dispose of less trash per household than municipalities without them. Given how much trash U.S. residents produce, the negative environmental effects associated with trash disposal, as well as how much the U.S. Environmental Protection Agency advocates for PAYT, it is important to closely analyze whether these programs actually do their job. This paper formally analyzes the effects of PAYT programs using the Massachusetts Department of Environmental Protection’s trash disposal data from 2011-2015. After controlling for municipality and time heterogeneity, my analysis shows that PAYT programs reduce trash per household by a …

Estimation Of The Virtual Water Content Of Main Crops On The Korean Peninsula Using Multiple Regional Climate Models And Evapotranspiration Methods, Chul-Hee Lim, Seung Hee Kim, Yuyoung Choi, Menas Kafatos, Woo-Kyun Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

Sustainable agriculture in the era of climate change needs to find solutions for the retention and proper utilization of water. This study proposes an ensemble approach for identifying the virtual water content (VWC) of main crops on the Korean Peninsula in past and future climates. Ensemble results with low uncertainty were obtained using three regional climate models, five potential evapotranspiration methods, and the Environmental Policy Integrated Climate (EPIC) crop model. The productivity results of major crops (rice and maize) under climate change are likely to increase more than in the past based on the ensemble results. The ensemble VWC is …

An Evaluation Of Emergent Macrophytes And Use Among Groups Of Aquatic Taxa, Kristopher J. Stahr, Mark A. Kaemingk

School of Natural Resources: Faculty Publications

Aquatic vegetation serves an important ecological role. Previous research on the interactions of macrophytes and aquatic organisms has focused primarily on submersed macrophytes due to their structural complexity and associated ecological impacts. However, the role of emergent vegetation is far less understood and often overlooked because they lack structural complexity. We evaluated 3 common emergent macrophytes and an open water habitat, and determined use among multiple aquatic taxa. Pelican Lake, Nebraska, USA, served as our study system because it is dominated by 3 emergent macrophytes: common cattail (Typha latifolia), softstem bulrush (Schoenoplectus tabernaemontani), and common reed …

Recreational Angler Site Choice And Behavior Within Midwestern Reservoirs, Brian S. Harmon

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

Anglers are the dominant predator in most inland fisheries. Although anglers make decisions across multiple scales, most research targets larger spatial and temporal scales of angler behavior, and thus little is known regarding angler behavior within a fishing trip. Outcomes of within-trip behavior affect larger spatial and temporal scales and are thus important to the management of recreational fisheries. Bank angler site choice was recorded at four reservoirs in the Salt Valley system across the open-water season of 2016. Previous research indicated that angler distribution did not match the distribution of fish, so another approach was taken. Counts of anglers …
