Protecting Brazilian Amazon Indigenous Territories Reduces Atmospheric Particulates And Avoids Associated Health Impacts And Costs, Paula R. Priest, Florencia Sangermano, Allison Bailey, Victoria Bugni, María Del Carmen Villalobos-Segura, Nataly Pimiento-Quiroga, Peter Daszak, Carlos Zambrana-Torrelio

Geography

Indigenous territories are considered important for conservation, but little is known about their role in maintaining human health. Here we quantified the potential human health and economic benefits of protecting these territories in the Brazilian Amazon, by using cardiovascular and respiratory diseases cases, pollutant and forest cover data. Between 2010 and 2019, 1.68 tons of Particulate Matter of small size (PM2.5) were released every year, with negative effects for human health. A lower number of infections was also found in municipalities with more forested areas, and with a low level of fragmentation, which probably is related to the …


Examining Current Bias And Future Projection Consistency Of Globally Downscaled Climate Projections Commonly Used In Climate Impact Studies, Lucas Berio Fortini, Lauren R. Kaiser, Abby Frazier, Thomas W. Giambelluca 2023 Pacific Island Ecosystems Research Center

Examining Current Bias And Future Projection Consistency Of Globally Downscaled Climate Projections Commonly Used In Climate Impact Studies, Lucas Berio Fortini, Lauren R. Kaiser, Abby Frazier, Thomas W. Giambelluca

Geography

The associated uncertainties of future climate projections are one of the biggest obstacles to overcome in studies exploring the potential regional impacts of future climate shifts. In remote and climatically complex regions, the limited number of available downscaled projections may not provide an accurate representation of the underlying uncertainty in future climate or the possible range of potential scenarios. Consequently, global downscaled projections are now some of the most widely used climate datasets in the world. However, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we explore the utility of two …

Socioeconomic Geographies And Municipal Decision Making Of New York's Climate Smart Communities Program, Stephen Corbisiero 2023 Binghamton University

Socioeconomic Geographies And Municipal Decision Making Of New York's Climate Smart Communities Program, Stephen Corbisiero

Digital and Data Studies Student Scholarship

Nearly all of New York’s residents live in a municipality designated as a Climate Smart Community, but few are familiar with one of the state’s major legislative accomplishments. The initiative allows municipalities to earn points toward a climate smart certification by implementing sustainable technologies in their communities, which in turn makes them eligible for increased grant funding from New York State. As climate change begins to have a greater impact on human and natural life, investing in green infrastructure has never been more important. New York’s Climate Smart Communities program is widespread, but adoption rates vary greatly throughout the state …


Development Of A Historic Digital Elevation Model (Hdem) From Archival Aerial Imagery Over The Black Mountain Alluvial Fan, Canada, Emma Menio 2023 University of Arkansas-Fayetteville

Development Of A Historic Digital Elevation Model (Hdem) From Archival Aerial Imagery Over The Black Mountain Alluvial Fan, Canada, Emma Menio

Graduate Theses and Dissertations

In a rapidly changing Arctic, reconstructing landscapes pre-warming is essential to understanding impacts due to climate-inducted geomorphic change. High-latitude elevation datasets extend temporally back to the 2000s, while region-wide warming became measurable in the 1980s. Historic aerial imagery archives provide datasets of high-resolution imagery from the mid- to late- 1900s with stereo-capability that can be harnessed to create historic digital elevation models, or hDEMs. A major issue with reconstructing a surface from the past is finding a way to constrain it in space, given a lack of ground control from that era, especially at high latitudes. The main purpose of …


Endangered Whales Still Get Tangled In Fishing Gear: Let’S Change The Way We Approach The Problem, Tora Johnson 2023 University of Maine at Machias

Endangered Whales Still Get Tangled In Fishing Gear: Let’S Change The Way We Approach The Problem, Tora Johnson

Maine Policy Review

The Gulf of Maine lobster industry has been roiled by conflict over whale entanglement for decades. With fewer than 350 North Atlantic right whales remaining, federal regulators are again seeking to implement new measures to protect them from tangling in fishing gear, while the lobster industry faces myriad challenges. My 2005 book Entanglements examined the complex and fraught debate between whale advocates and fishermen. Each side believed the other was inherently evil, greedy, and unduly powerful. Of course, the truth lay somewhere between. Between them were the brave souls who went to sea to wrestle fishing gear off of entangled …

Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason 2023 University of Arkansas-Fayetteville

Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason

Graduate Theses and Dissertations

Shortleaf pine (Pinus echinata) approaches the westernmost limits of its range in the Arkansas Ozarks. Despite heavy logging of shortleaf pine throughout its range during the 19th and 20th centuries, the species was not easily accessible for harvest and transportation in the most rugged areas of the Boston Mountains and, as a result, there are a few extant stands of old-growth shortleaf pine in the region. The shortleaf pine stands in the interior Boston Mountains are unusual in that they exist primarily above bluff lines at topographic breaks in the hardwood canopy and are not disturbed by fire as frequently …

People, Place, And Planet: Global Review Of Use-Inspired Research On Water-Related Ecosystem Services In Urban Wetlands, Jason Sauer, Heejun Chang 2023 Portland State University

People, Place, And Planet: Global Review Of Use-Inspired Research On Water-Related Ecosystem Services In Urban Wetlands, Jason Sauer, Heejun Chang

Geography Faculty Publications and Presentations

With climate change and urbanization, city planners and developers have increasing interest and practice in constructing, restoring, or incorporating wetlands as forms of green infrastructure to maintain water-related ecosystem services (WES). We reviewed studies that valued in functional or monetary units the water regulation and purification services of urban wetlands around the globe. We used the adaptive management cycle (AMC) as a heuristic to determine the step that a study would represent in the AMC, the connections between the cycle steps that were used or considered, and the stakeholders involved. Additionally, we identified the social, ecological, and/or technological dimension(s) of …

Relating Social, Ecological, And Technological Vulnerability To Future Flood Exposure At Two Spatial Scales In Four U.S. Cities, Jason Sauer, Arun Pallathadka, Idowu Ajibade, Marta Berbés-Blázquez, Heejun Chang, Elizabeth M. Cook, Nancy B. Grimm, David Iwaniec, Robert Lloyd, Gregory C. Post

Geography Faculty Publications and Presentations

Flooding occurs at different scales and unevenly affects urban populations based on the broader social, ecological, and technological system (SETS) characteristics particular to cities. As hydrological models improve in spatial scale and account for more mechanisms of flooding, there is a continuous need to examine the relationships between flood exposure and SETS drivers of flood vulnerability. In this study, we related fine-scale measures of future flood exposure—the First Street Foundation's Flood Factor and estimated change in chance of extreme flood exposure—to SETS indicators like building age, poverty, and historical redlining, at the parcel and census block group (CBG) scales in …


Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire 2023 Western Michigan University

Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire

Masters Theses

Previous studies have identified that changes in plant phenology are most likely induced by climate variability. One such change is the end of season (EOS) for deciduous forests in the United States. In essence, the EOS represents the end of plant productivity for a given year; the phase in which plant dormancy is reached. However, our wealth of knowledge on plant phenology largely overlooks the phases that occur in autumn, especially the EOS, with many previous studies focusing on spring phenology. This study uses remote sensing MODIS aerial imagery data and historical meteorological data to analyze any relationships that may …


Sc-Fuse: A Feature Fusion Approach For Unpaved Road Detection From Remotely Sensed Images, Aniruddh Saxena 2023 University of Nebraska-Lincoln

Sc-Fuse: A Feature Fusion Approach For Unpaved Road Detection From Remotely Sensed Images, Aniruddh Saxena

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

Road network extraction from remote sensing imagery is crucial for numerous applications, ranging from autonomous navigation to urban and rural planning. A particularly challenging aspect is the detection of unpaved roads, often underrepresented in research and data. These roads display variability in texture, width, shape, and surroundings, making their detection quite complex. This thesis addresses these challenges by creating a specialized dataset and introducing the SC-Fuse model.

Our custom dataset comprises high resolution remote sensing imagery which primarily targets unpaved roads of the American Midwest. To capture the diverse seasonal variation and their impact, the dataset includes images from different …


Vaupés Multilingualism And The Substance Of Language, Stephen Hugh-Jones 2023 University of Cambridge

Vaupés Multilingualism And The Substance Of Language, Stephen Hugh-Jones

Tipití: Journal of the Society for the Anthropology of Lowland South America

By focusing on ordinary conversational language, relying on a notion of “group” derived from unilineal descent theory, and neglecting mythology and ritual, studies of Vaupés Tukanoan multilingualism have inadvertently tended to reproduce a Western ideology of language as marking national identity and concerned with conveying meaning. This paper suggests that attention to musical, ritual, and shamanic contexts reveals multilingualism in a different light, with ritual speech acts as constitutive of social groups, names as vehicles of reproduction, and breath as a substance-like bodily element and source of vitality. The more esoteric, rhetorical, musical, or visual ornamentation is given to breath, …


Clever Animals: Naturalcultural Interactions In Karitiana Hunting Practices (Rondônia, Brazil), Felipe Vander Velden 2023 Universidade Federal de São Carlos

Clever Animals: Naturalcultural Interactions In Karitiana Hunting Practices (Rondônia, Brazil), Felipe Vander Velden

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article addresses hunting practices and human-animal relations among the Karitiana, a Tupi-Arikém-speaking indigenous people in the southwestern Brazilian Amazon, asserting that if humans can learn from animals in long-lasting hunting experiences in the forest, animals can also learn how to deal with their human predators as well as their knowledge and techniques. Furthermore, animals must be understood here as species and individuals. This is an almost natural conclusion drawn from Amazonian ethnography, which suggests that distinctions between humans and the nonhumans that we call animals are not classified according to a categorization in which human beings have resourcefulness and …

The Age Of The Onanya - Regarding The Spread Of Ayahuasca Use Throughout The Ucayali Basin, Carlos Suárez-Álvarez 2023 Independent scholar

The Age Of The Onanya - Regarding The Spread Of Ayahuasca Use Throughout The Ucayali Basin, Carlos Suárez-Álvarez

Tipití: Journal of the Society for the Anthropology of Lowland South America

The spread of ayahuasca shamanism throughout the Upper Amazon has become a matter of debate among scholars since, in 1994, anthropologist Peter Gow formulated the controversial suggestion that it could be a recent phenomenon in the Ucayali basin, usually considered the stronghold of a millenary tradition. Following Gow, Brabec de Mori argued that the Shipibo-Conibo people, a paradigmatic example of the antique practice of ayahuasca shamanism, adopted both the brew and the associated shamanic practices in a “relatively recent” past. Gow and Brabec pointed at the Maynas missions as the origin of this shamanic complex, and the mestizo and Cocama …


Into An Interference Zone: Childbirth And Care Among Mehinako People, Aline Regitano 2023 University of Sao Paulo

Into An Interference Zone: Childbirth And Care Among Mehinako People, Aline Regitano

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article addresses issues of care and corporeality during gestation, childbirth, the postpartum period, and childcare through a case study conducted with Mehinako people. Among this Amazonian people, care forms the person, having an elementary function in the daily construction of kinship relations through means of affection. A recent trend has caused expressive transformations in the way women experience corporeality and the making of a person: the displacement of birth from the home to hospitals, motivated by women’s fear, desire, and curiosity. In the city, Indigenous women transit through medical institutions, which I propose may be read as interference zones …


Jean E. Jackson: A Pioneering Ethnographer In The Colombian Amazon, Patience Epps, Danilo Paiva Ramos, Flora Dias Cabalzar 2023 University of Texas at Austin

Jean E. Jackson: A Pioneering Ethnographer In The Colombian Amazon, Patience Epps, Danilo Paiva Ramos, Flora Dias Cabalzar

Tipití: Journal of the Society for the Anthropology of Lowland South America

This essay celebrates the work of Jean E. Jackson, a pioneering female ethnographer who devoted most of her fifty-year career to the Indigenous peoples of Colombia. Her research, represented in an extensive set of publications from the early 1970s to the present, engages with themes of identity, stigma, and social inequality, manifested across a range of contexts. Jackson’s ethnographic contributions include her ground-breaking early work on Indigenous Tukanoan society in the Colombian Vaupés, focusing on the practice of linguistic exogamy (obligatory marriage across language groups) among the Bará people. Later, she expanded her focus to address Indigenous experiences in the …
