A long-time US activist against the deleterious impact of oil-palm deforestation in Southeast Asia learned a great deal about the indigenous peoples’ struggles there to gain control over their lives and livelihoods.

Socio-Environmental Drought Response In A Mixed Urban-Agricultural Setting: Synthesizing Biophysical And Governance Responses In The Platte River Watershed, Nebraska, Usa, Samuel C. Zipper, Kelly Helm Smith, Betsy Breyer, Jianxiao Qui, Anthony Kung, Dustin Herrmann

National Drought Mitigation Center: Faculty Publications

Ensuring global food and water security requires a detailed understanding of how coupled socio-environmental systems respond to drought. Using the Platte River Watershed in Nebraska (USA) as an exemplar mixed urban-agricultural watershed, we quantify biophysical response to drought in urban (Lincoln NE) and agricultural systems alongside a qualitative analysis of governance response and adaptive capacity of both sectors. Synthesis of results highlights parallels and discontinuities between urban and agricultural preparations for and response to drought. Whereas drought prompted an increase in well installations and expansion of water-intensive crops, e.g., corn, in the agricultural sector, outdoor water use restrictions rapidly curtailed …

Camera System Considerations For Geomorphic Applications Of Sfm Photogrammetry, Adam R. Mosbrucker, Jon J. Major, Kurt R. Spicer, John Pitlick

United States Geological Survey: Staff Publications

The availability of high-resolution, multi-temporal, remotely sensed topographic data is revolutionizing geomorphic analysis. Three-dimensional topographic point measurements acquired from structure-from-motion (SfM) photogrammetry have been shown to be highly accurate and cost-effective compared to laser-based alternatives in some environments. Use of consumer-grade digital cameras to generate terrain models and derivatives is becoming prevalent within the geomorphic community despite the details of these instruments being largely overlooked in current SfM literature.

A practical discussion of camera system selection, configuration, and image acquisition is presented. The hypothesis that optimizing source imagery can increase digital terrain model (DTM) accuracy is tested by evaluating accuracies …

Computational Modeling Of A Williams Cross Flow Turbine, Sajjan Pokhrel

Browse all Theses and Dissertations

Hydropower is not only the most used renewable energy source in the United States, but in the world. While it is well known that large hydropower facilities, like the Hoover Dam, provide large amounts of electrical power, there is also a tremendous opportunity for hydroelectric power generation from small scale facilities that has largely been overlooked. The work being presented here studies a new cross flow turbine called the Williams Cross Flow Turbine (WCFT), which was designed to extract electric energy from low head, run-of-the-river, small hydropower sites. To spur the implementation of the WCFT in small hydropower applications, and …

Recovery And Resilience Of Urban Stream Metabolism Following Superstorm Sandy And Other Floods, Alexander J. Reisinger, Emma J. Rosi, Heather A. Bechtold, Thomas R. Doody, Sujay S. Kaushal, Peter M. Groffman

Publications and Research

Urban streams are exposed to multiple different stressors on a regular basis, with increased hydrological flashiness representing a common urban stream stressor. Stream metabolism, the coupled ecosystem functions of gross primary production (GPP) and ecosystem respiration (ER), controls numerous other ecosystem functions and integrates multiple processes occurring within streams. We examined the effect of one large (Superstorm Sandy) and multiple small and moderately sized flood events in Baltimore, Maryland, to quantify the response and recovery of urban stream GPP and ER before and after floods of different magnitudes. We also compared GPP and ER before and after Superstorm Sandy to …

A History Of The Participatory Map, Jo Guldi

History Faculty Publications

This article tells, for the first time, the story of the history of the participatory map: that is, the many-to-many map-making techniques that most people are familiar with through smartphone apps and Google maps. Archival research in previously untapped archives traces the origins of participatory mapping in subaltern conversations around the world, its embrace in the modern academy and development circles, its place in the World Bank, and its conversion to online formats like Google Maps and Open Street Map. The story begins in surprising places, as international networks in the 1970s began experimenting with many-to-many mapping, their members spanning …

Agricultural Land Use, Watershed Characteristics, And Hydrological Forces Contributing To The Impairment Of A Shallow Lake In The Western Corn Belt Ecoregion, Lynn Schultz

All Graduate Theses, Dissertations, and Other Capstone Projects

The Lake Titlow watershed (approximately 35,000 acres) in south-central Minnesota is part of the Minnesota River Basin. The lake is listed in the draft 2010 Clean Water Act Section 303d for nutrient pollution, eutrophication, and biological indicators for impairment of aquatic life and recreational use. Over 90 percent of pre-settlement wetlands are currently drained for agricultural land use. The Lake Titlow watershed is over 80 percent row crops and land use is implicated as a primary cause of impairment in the lake.

Water samples were collected from the Lake Titlow tributaries McLeod-Sibley Judicial Ditch Number 18 (JD18), Sibley County Ditch …

Assessment Of Coastal Governance For Climate Change Adaptation In Kenya, Lenice Ojwang, Sergio Rosendo, Louis Celliers, David Obura, Anastasia Muiti, James Kamula, Maina Mwangi

East Africa

The coastline of Kenya already experiences effects of climate change, adding to existing pressures such as urbanization. Integrated coastal management (ICM) is increasingly recognized as a key policy response to deal with the multiple challenges facing coastal zones, including climate change. It can create an enabling governance environment for effective local action on climate change by facilitating a structured approach to dealing with coastal issues. It encompasses the actions of a wide range of actors, including local governments close to people and their activities affected by climate change. Functioning ICM also offers opportunities for reducing risks and building resilience. This …

A Sustainability Index For Small Island Developing States., Philip Van Beynen, Fenda A. Akiwumi, Kaya Van Beynen

USF St. Petersburg Campus Faculty Publications

This paper proposes a novel approach to measuring the progress of Small Island Developing States (SIDS) towards sustainable development (SD) as set by the UN Sustainable Development Goals 2030. Currently, these goals do not provide adequate guidance on how countries might measure their progress towards sustainability. We use these goals and a subset of their targets to develop an index with concrete targets, through the use of pertinent sustainability indicators, that SIDS should aim to achieve a sustainable society. In addition to the three categorical pillars of sustainable development (social, economic, and environmental), we included the category Climate Change and …

A Model-Based Assessment Of Potential Impacts Of Man-Made Reservoirs On Precipitation, Jesse Winchester, Rezaul Mahmood, William Rodgers, Faisal Hossain, Eric Rappin, Joshua D. Durkee, Themis Chronis

High Plains Regional Climate Center: Staff Publications

Land-use land-cover change (LULCC) plays an important role in weather and climate systems. Human modifications of land cover include building reservoirs and thus creating artificial lakes for multipurpose use. In this research, the authors have completed a Weather Research and Forecasting (WRF) Model–based assessment of impacts of two large parallel lakes on precipitation. This area is located in the western part of the states of Kentucky and Tennessee and known as the Land between the Lakes (LBL). To determine the impacts, this study has replaced the lakes with grass, deciduous forests, and bare soil and conducted model simulations for three …

The Upper Columbia Basin Network I&M (Inventory and Monitoring) program and Craters of the Moon National Monument and Preserve are collaborating to monitor winter bat use in Arco Tunnel, which is a safely accessed cave in the northern portion of the monument that consistently has been found with the largest number of bats (~30/year) among the set of caves recently inventoried. The standard operating procedures documented here and the methods described in the associated protocol narrative will also be used to periodically inventory other caves within the monument and surrounding preserve as park resources and safety (winter environmental and …

Human Dimensions Of Habitat Loss In The Plains And Prairie Potholes Ecoregion, Lily A. Sweikert

Electronic Theses and Dissertations

The Plains and Prairie Potholes Ecoregion (PPPE), is located in the north-central contiguous United States and is one of the most imperiled grassland regions in the world. Most of the region is privately owned and used for the production of agricultural commodities. In addition to its direct benefits to humanity, the PPPE provides multiple ecosystem services including, soil and water quality improvements, carbon sequestration, weather amelioration, and wildlife habitat. Recent increases in expansion of row crop agriculture concerns conservation practitioners about the long-term integrity of the PPPE. Conservation practitioners are looking to improve their private landowner conservation initiatives in the …

Using Remote Sensing To Estimate Crop Water Use To Improve Irrigation Water Management, Arturo Reyes-Gonzalez

Electronic Theses and Dissertations

Irrigation water is scarce. Hence, accurate estimation of crop water use is necessary for proper irrigation managements and water conservation. Satellite-based remote sensing is a tool that can estimate crop water use efficiently. Several models have been developed to estimate crop water requirement or actual evapotranspiration (ETa) using remote sensing. One of them is the Mapping EvapoTranspiration at High Resolution using Internalized Calibration (METRIC) model. This model has been compared with other methods for ET estimations including weighing lysimeters, pan evaporation, Bowen Ratio Energy Balance System (BREBS), Eddy Covariance (EC), and sap flow. However, comparison of METRIC model outputs to …

Land Surface Phenologies And Seasonalities Using Cool Earthlight In Temperate And Tropical Croplands, Woubet Gashaw Alemu

Electronic Theses and Dissertations

In today’s world of increasing food insecurity due to more frequent and extreme events (droughts, floods), a comprehensive understanding of global cropland dynamics is critically needed. Land surface parameters derived from the passive microwave Advanced Microwave Scanning Radiometer on EOS (AMSR-E) and AMSR2 data enable monitoring of cropland dynamics and they can complement visible to near infrared (VNIR) and thermal infrared (TIR) data. Passive microwave data are less sensitive to atmospheric effects, cloud contamination, and solar illumination constraints resulting in finer temporal resolution suitable to track the temporal progression of cropland cover development compared to the VNIR data that has …

America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz

Honors Theses

In 2000, atmospheric chemist, Paul J. Crutzen, and limnologist, Eugene Stoermer, formally proposed the idea of “the Anthropocene,” a new geologic epoch in which humans are the dominant force shaping the Earth. To claim the Anthropocene's existence is to declare that human actions have altered the Earth in such a way that geologic indicators render it a distinct epoch in the stratification of geologic time. This new epoch emerges as a consequence of increased technological development employed to accommodate an anthropocentric human existence. That is, rapid advancements in technology have driven the transformation from a primarily naturally controlled planet to …

Environment And Sustainability In Nevada, Jennifer Stevens, Genevieve Minter, Robert Futrell

Social Health of Nevada Reports

When the inaugural Earth Day launched the first environmental decade in the U.S. more than forty years ago, protecting our air, water, land and other natural resources seemed a relatively straightforward task. Environmental polluters and exploiters would be brought to heel by tough laws. The U.S. and other industrialized nations responded to quality of life concerns associated with environmental degradation by adopting dozens of major environmental and resource policies and creating new institutions such as the U.S. Environmental Protection Agency to manage environmental programs. Following these national developments, states and local communities began systematic efforts to address environmental problems.

Species Distributions Models In Wildlife Planning: Agricultural Policy And Wildlife Management In The Great Plains, Joseph J. Fontaine, Christopher F. Jorgensen, Erica F. Stuber, Lutz F. Gruber, Andrew A. Bishop, Jeffrey J. Lusk, Eric S. Zach, Karie L. Decker

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We know economic and social policy has implications for ecosystems at large, but the consequences for a given geographic area or specific wildlife population are more difficult to conceptualize and communicate. Species distribution models, which extrapolate species-habitat relationships across ecological scales, are capable of predicting population changes in distribution and abundance in response to management and policy, and thus, are an ideal means for facilitating proactive management within a larger policy framework. To illustrate the capabilities of species distribution modeling in scenario planning for wildlife populations, we projected an existing distribution model for ring-necked pheasants (Phasianus colchicus) onto …

Accountability, Conservation And Community: Measuring The Local Economic Impacts Of Protected Areas, Catharine A.M. Brazeau

Theses and Dissertations (Comprehensive)

As a signatory to the Convention on Biological Diversity, Canada has committed to help protect biodiversity through an increase in effectively and equitably managed systems of protected areas (PAs) by 2020. If Canada fulfills this commitment, the country will see the largest expansion of PA networks in its history. Although employing ‘equitable and effective management’ suggests PAs have a responsibility to consider their effects on local stakeholders, on the whole, Canada’s PA agencies do not publicly and systematically report on their jurisdictions’ local economic impacts. To address this gap, this thesis aims investigate mechanisms for PA agencies to identify and …

Assessing Resilient Post-Disaster Recovery Of A Flash-Flood-Prone Area: A Study Of The City Of Jeddah, Kingdom Of Saudi Arabia, Abdurazag Tammar

Theses and Dissertations (Comprehensive)

Abstract

The increased incidence of natural disasters over recent decades has been accompanied by a corresponding dramatic proliferation of human casualties, economic damage and recovery costs. Post-disaster processes are therefore increasingly becoming the paramount focus of disaster-management stakeholders. Current research has noted the importance of improving community resilience with respect to household capacity, organizational capacity, and social capital, as the three main assessment dimensions to enable communities to recover effectively and efficiently from future disaster events. Community resilience involves proactive preparedness and mitigation initiatives. In the context of the Kingdom of Saudi Arabia, the lack of either precedent research or …

Power And Politics In Research Design And Practice: Opening Up Space For Social Equity In Interdisciplinary, Multi-Jurisdictional And Community-Based Research, Valoree Gagnon, Hugh Gorman, Emma Norman

Michigan Tech Publications, Part 1

Working collaboratively with communities is commonly considered a cornerstone of good practice in research involving social-ecological concerns. Increasingly, funding agencies also recognise that such collaborations are most productive when community partners have some influence on the design and implementation of the projects that benefit from their participation. However, researchers engaged with this work often struggle to actively engage community members in this way and, in particular, Indigenous peoples. In this article, we argue that useful strategies for facilitating such engagement are to leave space in the research plan for questions of interest to community partners and to encourage equitable interactions …

Evaporation From A Shallow, Saline Lake In The Nebraska Sandhills: Energy Balance Drivers Of Seasonal And Interannual Variability, Diego Andrés Riveros-Iregui, John Lenters, Colin Peake, John T. Ong, Nathan C. Healey, Vitaly A. Zlotnik

Department of Earth and Atmospheric Sciences: Faculty Publications

Despite potential evaporation rates in excess of the local precipitation, dry climates often support saline lakes through groundwater inputs of water and associated solutes. These groundwater-fed lakes are important indicators of environmental change, in part because their shallow water levels and salinity are very sensitive to weather and climatic variability. Some of this sensitivity arises from high rates of open-water evaporation, which is a dominant but poorly quantified process for saline lakes. This study used the Bowen ratio energy budget method to calculate open-water evaporation rates for Alkali Lake, a saline lake in the Nebraska Sandhills region (central United States), …

Assessing Riparian Ecosystem Condition And Monitoring Recovery From Natural And Anthropogenic Disturbance, Rachel Powers

Graduate Student Theses, Dissertations, & Professional Papers

Riparian ecosystems are the transition zones between river systems and uplands. They provide many valuable ecological functions including creating habitat for wildlife, stabilizing banks from erosion and providing a buffer that prevents excess nutrients from entering streams. Fires and other disturbances alter the function of these ecosystems. Currently, there is a lack of broadly used standardized assessments and monitoring methods in riparian areas within our current water policy framework. This study aims to examine this gap in riparian ecosystem protection by reviewing the assessment methods currently in use, selecting one method for field testing, and analyzing the effort involved in …

Fish Spawning Aggregations: Where Well-Placed Management Actions Can Yield Big Benefits For Fisheries And Conservation, Brad Erisman, William Heyman, Shinichi Kobara, Tal Ezer, Simon Pittman, Octavio Aburto-Oropeza, Richard S. Nemeth

CCPO Publications

Marine ecosystem management has traditionally been divided between fisheries management and biodiversity conservation approaches, and the merging of these disparate agendas has proven difficult. Here, we offer a pathway that can unite fishers, scientists, resource managers and conservationists towards a single vision for some areas of the ocean where small investments in management can offer disproportionately large benefits to fisheries and biodiversity conservation. Specifically, we provide a series of evidenced-based arguments that support an urgent need to recognize fish spawning aggregations (FSAs) as a focal point for fisheries management and conservation on a global scale, with a particular emphasis placed …
