The Battle For The Sea: Tourism Development And Public Ocean Access In Jambiani, Zanzibar, Sophie Beauchesne

Independent Study Project (ISP) Collection

The battle for coastal access is a prevalent and controversial issue in both the Global North and the Global South (Mongeau, 2001; Ojo, 2013). Due to investment in coastal land, vulnerable communities around the world are losing their access to the sea (Ojo, 2013; Bennett, Govan & Satterfield, 2015). Battles for ocean access in the Global North tend to focus on recreational activities, but what is to be said about ocean access in the Global South, where access to the sea is needed for the survival of entire communities? (Mongeau, 2001;). Using geographical mapping, environmental condition assessments and open-ended interviews …

Energy Literacy In Portugal: A System Map And Framework To Increase Energy Literacy Through The Renewable Energy Transition, Molly S. Fox

Independent Study Project (ISP) Collection

Western society lives with a great dependence and an almost simultaneous ignorance of energy consumption (van den Broek, 2019). The systemic landscape of energy knowledge and dissemination is more critical than ever as Portugal races to meet decarbonization goals. This paper fills a knowledge gap by updating the current social landscape of energy literacy in Portugal through a comprehensive system map and framework to increase energy literacy levels through the renewable energy transition. By conducting a semi-systematic literature review, meta-narratives and themes were identified and used to create theoretical concepts, a framework, and a system map. This research found that …

Institute for ECHO Faculty Books and Book Chapters

Dragon fruit is widely grown in Southeast Asia and other tropical or subtropical regions. As a high-value cash crop ideal for exportation, dragon fruit cultivation has boomed during the past decade in southern Vietnam. Light supplementing during the winter months using artificial lighting sources is a widely adopted cultivation technique to boost productivity in the major dragon fruit planting regions of Vietnam. The application of electric lighting at night leads to a significant increase of nighttime light (NTL) observable by satellite sensors. The strong seasonality signal of NTL in dragon fruit cultivation enables identifying dragon fruit plantations using NTL images. …

A Statistical Method For Quantifying Animal Interaction; Combining Time Geography And Simulation, Zachary J. Smith

USF Tampa Graduate Theses and Dissertations

Dynamic interaction (DI) describes the synchronous interaction of one or more individual animals over time. Current methods to quantify DI from tracking data are lacking. They typically require synchronized tracking data which limits their applicability to most studies. They also often do not have built-in tests of significance to evaluate interaction, and if so, rely on random walk models that lack biological realism. This research aimed to develop and evaluate a new way of measuring animal interaction that overcomes these limitations. The goal was to create a statistical method for quantifying and evaluating interaction that is relevant across computational, behavioural, …

Geothermal Development In Kenya: Gender Based Socio-Cultural And Socio-Economic Implications, Faye N. Ricker

USF Tampa Graduate Theses and Dissertations

This dissertation is an ethnographic case study that analyzes the gendered socio-cultural and socio-economic implications for a community that was displaced in order to develop a geothermal energy system in Kenya. The implications are rendered particularly interesting because the displaced community is also one of the communities served by the geothermal power grid. The analysis employs a composite framework of Feminist Political Ecology and the Political Ecology of Climate Change Mitigation. This work explores gendered perceptions and control of energy, livelihood activities, place attachment, and the cultural/spiritual significance of geothermal energy.

Geothermal energy is a potentially promising source of low-carbon …

The Natural Gas Hydrate(NGH) is known as the most promising strategic resource in the 21st century because of its huge energy density, convenient use, high combustion value, and cleanness, and it is an alternative energy source with huge potential for conventional oil and gas resources. The occurrence of the NGH in the Sanlutian area of Muli Coalfield in Qinghai Province is the result of the interaction between the abundant gas sources and the hydrate stability zone in cold highland areas. The NGH in coal-bearing strata is defined as the coal measure gas hydrate, belonging to unconventional coal measure gases. To …

Digital And Spatial Humanities Mapping: Eurasia-Pacific Early Trade And Belief Linkages, Igor Sitnikov, David Blundell

Monsoon: South Asian Studies Association Journal

The Eurasia-Pacific is a dynamic region of rapid economic growth, cultural awareness, natural resource exploration, and military buildup. The concept of the region is relatively new, featuring contested vast areas of geo-resource space of numerous cultures and languages. The current findings in anthropology and archaeology and even its more specific subfields such as folklore are important contribution to the understanding of periodic environmental changes and technical innovations were the main forces of transformations in social structures that have determined the mechanisms and levels of cross-cultural trade activity across the region. We have traced early trade and belief linkages across Eurasia-Pacific …

Ganges In Indian Sculpture And Literature: Mythology And Personification, Nalini Rao

Monsoon: South Asian Studies Association Journal

The river Ganges is a symbol of wealth, purity and eternity, and its sacred waters have inspired sages, philosophers, and artists in India who have immortalized its divine imagery. However, it has rarely been understood from a historical point of view, as to how it became so sacred and to view it from a multi-dimensional and interdisciplinary perspective with an accumulation of layers of historical thought and practices, provides a rationale for the living practices around the river. The paper explores the evolution of the concept of sacredness and eternity of River Ganges through art- historical and archaeological evidence. It …

Climate Change Adaptation, Migration, And Promising Developments For Pacific Island States, Ashley Jonas

Department of Environmental Studies: Undergraduate Student Theses

The people of the Pacific Islands face an existential crisis due to climate change, despite the fact that they are the least responsible for contributing to carbon emissions. The effects of climate change, namely sea-level rise, pose a verified threat to low-lying islands, infiltrating water supplies, crops, and infrastructure. As a result, there is a need for improved solutions for adapting to the impacts of climate change and for easier access to legal migration pathways when the consequences are insurmountable. Through comparative discourse analysis of scholarly sources, intergovernmental policies, and non-governmental organizations, the thesis finds that Small Island Developing States …

Canopy Spectral Reflectance Detects Oak Wilt At The Landscape Scale Using Phylogenetic Discrimination, Gerard Sapes, Cathleen Lapadat, Anna K. Schweiger, Jennifer Juzwik, Rebecca Montgomery, Hamed Gholizadeh, Philip A. Townsend, John A. Gamon, Jeannine Cavender-Bares

School of Natural Resources: Faculty Publications

The oak wilt disease caused by the invasive fungal pathogen Bretziella fagacearum is one of the greatest threats to oak-dominated forests across the Eastern United States. Accurate detection and monitoring over large areas are necessary for management activities to effectively mitigate and prevent the spread of oak wilt. Canopy spectral reflectance contains both phylogenetic and physiological information across the visible near-infrared (VNIR) and short-wave infrared (SWIR) ranges that can be used to identify diseased red oaks. We develop partial least square discriminant analysis (PLS-DA) models using airborne hyperspectral reflectance to detect diseased canopies and assess the importance of VNIR, SWIR, …

School of Natural Resources: Faculty Publications

White‐tailed deer (Odocoileus virginianus) and hunters on 2 Wildlife Management Areas (WMAs) within the Chattahoochee National Forest of northern Georgia, USA, significantly declined in number from the 1980s to 2018. Managers were interested in understanding how they could manipulate hunter distribution according to deer management goals. To understand the spatial distribution of hunting pressure and factors driving hunter resource selection, we analyzed GPS tracking data from 58 deer hunters over the 2018–2019 and 2019–2020 hunting seasons. We evaluated hunter selection on 3 spatial scales relative to elevation, slope, and distance from roads, trails, wildlife openings, deciduous forest, mixed …

Autonomous, Long-Range, Sensor Emplacement Using Unmanned Aircraft Systems, Adam Plowcha, Justin Bradley, Jacob Hoberg, Thomas Ammon, Mark Nail, Brittany Duncan, Carrick Detweiler

School of Computing: Faculty Publications

Automated, in-ground sensor emplacement can significantly improve remote, terrestrial, data collection capabilities. Utilizing a multicopter, unmanned aircraft system (UAS) for this purpose allows sensor insertion with minimal disturbance to the target site or surrounding area. However, developing an emplacement mechanism for a small multicopter, autonomy to manage the target selection and implantation process, as well as long-range deployment are challenging to address. We have developed an autonomous, multicopter UAS that can implant subsurface sensor devices. We enhanced the UAS autopilot with autonomy for target and landing zone selection, as well as ensuring the sensor is implanted properly in the ground. …

Ecosystem Duties, Green Infrastructure, And Environmental Injustice In Los Angeles, Sayd Randle

Research Collection College of Integrative Studies

In Los Angeles, water managers and environmentalist NGOs champion green infrastructure retrofits, installations intended to maximize the water-absorbing capacity of the urban landscape. In such arrangements, the work of water management is necessarily spread among a more-than-human community, including (but certainly not limited to) humans, plants, soils, and gravels. This article analyzes the human labor within these collaborations, tracking when and how this work gets enrolled in networks of water management and circuits of value. I develop the term ecosystem duties to characterize these exertions and as a useful analytic for assessing emergent dynamics of environmental justice.

Does Restoration Of Urban Riparian Zones Impact Stream Water Quality In Portland, Oregon, Ash Ivanov

University Honors Theses

Riparian zones influence urban stream quality through factors such as shading the stream, adding nutrients through leaf litter, stabilizing the stream banks to reduce turbidity, and filtering toxins out of the water. Riparian restoration often involves changing plant assemblage to be more diverse and include primarily native species instead of non-native, improving connection to the stream through changing stream morphology, improving species habitat, and reducing pollution. The goal of this study was to determine if urban riparian restoration projects in the region were successful, and if not, why that may be the case. The study was performed in the Portland, …

Landslide Detection In The Himalayas Using Machine Learning Algorithms And U-Net, Sansar Raj Meena, Lucas Pedrosa Soares, Carlos H. Grohmann, Cees Van Westen, Kushanav Bhuyan, Ramesh P. Singh, Mario Floris, Filippo Catani

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Event-based landslide inventories are essential sources to broaden our understanding of the causal relationship between triggering events and the occurring landslides. Moreover, detailed inventories are crucial for the succeeding phases of landslide risk studies like susceptibility and hazard assessment. The openly available inventories differ in the quality and completeness levels. Event-based landslide inventories are created based on manual interpretation, and there can be significant differences in the mapping preferences among interpreters. To address this issue, we used two different datasets to analyze the potential of U-Net and machine learning approaches for automated landslide detection in the Himalayas. Dataset-1 is composed …

The Role Of Place Attachment And Situated Sustainability Meaning-Making In Enhancing Student Civic-Mindedness: A Campus Farm Example, Brandon H. Sorge, Francesca A. Williamson, Grant A. Fore, Julia L. Angstmann

Scholarship and Professional Work - LAS

This research explores the role that place attachment and place meaning towards an urban farm play in predicting undergraduate students’ civic-mindedness, an important factor in sustainability and social change. In 2017 and 2018, three STEM courses at a private university in the Midwest incorporated a local urban farm as a physical and conceptual context for teaching course content and sustainability concepts. Each course included a four to six-week long place-based experiential learning (PBEL) module aimed at enhancing undergraduate STEM student learning outcomes, particularly place attachment, situated sustainability meaning-making (SSMM), and civic-mindedness. End-of-course place attachment, SSMM, and civic-mindedness survey data were …

The Tibetan Plateau and its surroundings, also known as the Third Pole, play an important role in the global and regional climate and hydrological cycle. Carbonaceous aerosols (CAs), including black carbon (BC) and organic carbon (OC), can directly or indirectly absorb and scatter solar radiation and change the energy balance on the Earth. CAs, along with the other atmospheric pollutants (e.g., mercury), can be frequently transported over long distances into the inland Tibetan Plateau. During the last decades, a coordinated monitoring network and research program named “Atmospheric Pollution and Cryospheric Changes” (APCC) has been gradually set up and continuously operated …

Environmental Science and Management Faculty Publications and Presentations

Roads are not the only determining factor for wildlife movement across the landscape, but due to the extensive distribution of the road network their impact can be dramatic. Although it has been well documented that roads decrease habitat connectivity for wildlife due to animal-vehicle collisions, habitat fragmentation, and avoidance behavior, approaches for identifying connectivity across the landscape often do not fully examine the barrier effect of roads. Here, we explored the extent of the impact of roadways on wildlife connectivity by using Omniscape to model connectivity including and without the barrier effect of roads, then evaluating the difference between these …

Chlorine Taste Threshold And Acceptability As A Water Disinfectant Among Indigenous Ngäbe And Non-Indigenous In Rural Panama, Ashley Osler

USF Tampa Graduate Theses and Dissertations

More than two billion people globally still lack access to safely managed drinking water (WHO & UNICEF, 2021). Although gains in access to water service over the past two decades have been large, universal access to safe and affordable drinking water (SDG 6, target 6.1) is not on track to be achieved. In Panama, safely managed drinking water access has not been measured. However, the data on basic water access illustrates the large disparities between rural and urban areas of Panama. While 98% of urban Panamanian households have basic access to water, only 86% of rural Panamanian households, and 54% …

Sustainable Land System Transformations In Shifting Cultivation Landscapes, Dominic Martin

Sustainability Seminar Series

During my talk, I will give a broad introduction on shifting cultivation, associated sustainability challenges, and the case of north‐eastern Madagascar. Thereafter I will focus on land system transformations in shifting cultivation landscapes – both in Madagascar and elsewhere – showing that their drivers and consequences are highly diverse and context‐dependent. This is calling for a critical and contextualized appraisal of the continuation of, as well as the transition away from shifting cultivation when designing land system

North American Breeding Bird Survey Underestimates Regional Bird Richness Compared To Breeding Bird Atlases, Roi Ankori-Karlinsky, Michael Kalyuzhny, Katherine F. Barnes, Andrew M. Wilson, Curtis Flather, Rosalind Renfrew, Joan Walsh, Edna Guk, Ronen Kadmon

Environmental Studies Faculty Publications

Standardized data on large-scale and long-term patterns of species richness are critical for understanding the consequences of natural and anthropogenic changes in the environment. The North American Breeding Bird Survey (BBS) is one of the largest and most widely used sources of such data, but so far, little is known about the degree to which BBS data provide accurate estimates of regional richness. Here, we test this question by comparing estimates of regional richness based on BBS data with spatially and temporally matched estimates based on state Breeding Bird Atlases (BBA). We expected that estimates based on BBA data would …
