Off-Peak Ndvi Correction To Reconstruct Landsat Time Series For Post-Fire Recovery In High-Latitude Forests, Cuizhen Wang, Aiai Wang, Dianfan Guo, Haibo Li, Shuying Zang

Faculty Publications

Collecting long-term satellite image series in high latitudes has been challenging due to its short growing season. For off-peak imagery, its reflective properties need to be corrected to maintain the spectral consistency. This study compares three statistical approaches to reconstructing a 30-year normalized difference vegetation index (NDVI) series for forest recovery assessment after the 1987 Black Dragon Fire in the Greater Hinggan Mountains Forest, Northeast China. To correct the off-peak NDVI to peak NDVI, the Landsat paired regression takes advantage of the scene-to-scene linear relationship between the two images, the GIMMS booster approach compensates the NDVI increment rate based on …

Machine Learning For Modeling Wildfire Susceptibility At The State Level: An Example From Arkansas, Usa, Abdullah Al Saim, Mohamed H. Aly

Geosciences Faculty Publications and Presentations

Fire susceptibility modeling is crucial for sustaining and managing forests among many other valuable land resources. With 56% of its area covered by forests, Arkansas is known as the "natural state". About 1000 wildfires occurred and burned more than 10,000 acres each year during 1981-2018. In this paper, we use remote-sensing-based machine learning methods to address the natural and anthropogenic factors influencing wildfires and model fire susceptibility in Arkansas. Among the 15 explored variables, potential evapotranspiration, soil moisture, Palmer drought severity index, and dry season precipitation were recognized as the most significant factors contributing to the fire density. The obtained …

Ecopsychologists' Vital Importance In The Time Of Climate Crises, Nicole B. Auckerman Psyd

Antioch University Dissertations & Theses

Ecopsychology is a systems-based philosophy that expands the therapeutic lens to include client interactions with and perceptions of the natural environment as an integral element of well-being or pathology. Ecopsychology, known forward as EP, also looks at the pathology of our culture and what kind of diagnoses lead to practices that put our planet at risk. In recent decades, the field has amassed a substantial amount of empirical evidence supporting its effectiveness but remains largely underutilized. First generation EP suggested a cultural reordering shifting away from consumer culture and reordering our way of life. Second generation posits working within the …

Avery, Kelly K. Caylor

Geography

Mapping the characteristics of Africa’s smallholder-dominated croplands, including the sizes and numbers of fields, can provide critical insights into food security and a range of other socioeconomic and environmental concerns. However, accurately mapping these systems is difficult because there is 1) a spatial and temporal mismatch between satellite sensors and smallholder fields, and 2) a lack of high-quality labels needed to train and assess machine learning classifiers. We developed an approach designed to address these two problems, and used it to map Ghana’s croplands. To overcome the spatio-temporal mismatch, we converted daily, high resolution imagery into two cloud-free composites (the …

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 …

Disentangling The Last 1,000 Years Of Human–Environment Interactions Along The Eastern Side Of The Southern Andes (34–52°S Lat.), William Nanavati, Cathy Whitlock, Maria Eugenia De Porras, Adolfo Gil, Diego Navarro, Gustavo Neme

Geography Faculty Publications and Presentations

Researchers have long debated the degree to which Native American land use altered landscapes in the Americas prior to European colonization. Human–environment interactions in southern South America are inferred from new pollen and charcoal data from Laguna El Sosneado and their comparison with high-resolution paleoenvironmental records and archaeological/ethnohistorical information at other sites along the eastern Andes of southern Argentina and Chile (34–52°S). The records indicate that humans, by altering ignition frequency and the availability of fuels, variously muted or amplified the effects of climate on fire regimes. For example, fire activity at the northern and southern sites was low at …

The Law Of Scale Independence, Jonathan D. Phillips

Geography Faculty Publications

Geography and geosciences deal with phenomena that span spatial scales from the molecular to the planetary, and temporal scales from instantaneous to billions of years. A strong reductionist tradition in geosciences and spatial sciences tempts us to seek to apply similar representations and process-based explanations across these vast-scale ranges, usually from a bottom-up perspective. However, the law of scale independence (LSI) states that for any phenomenon that exists across a sufficiently large range of scales, there exists a scale separation distance at which the scales are independent with respect to system dynamics and explanation. The LSI is evaluated here from …

Spatial Downscaling Of Goes-R Land Surface Temperature Over Urban Regions: A Case Study For New York City, Abdou Bah, Hamidreza Norouzi, Satya Prakash, Reginald Blake, Reza Khanbilvardi, Cynthia Rosenzweig

Publications and Research

The surface urban heat island (SUHI) effect is among the major environmental issues encountered in urban regions. To better predict the dynamics of the SUHI and its impacts on extreme heat events, an accurate characterization of the surface energy balance in urban regions is needed. However, the ability to improve understanding of the surface energy balance is limited by the heterogeneity of surfaces in urban areas. This study aims to enhance the understanding of the urban surface energy budget through an innovation in the use of land surface temperature (LST) observations from remote sensing satellites. A LST database with 5–min …

Social Production Of An Internal Colony: Urban Space In Black Chicago, 1945-1970, Connor M. Barnes

Swarthmore Undergraduate History Journal

Utilizing an internal colonial model combined with Henri Lefebvre’s ideas about the social production of space, this paper argues the urban space in Black Chicago was intentionally constructed to maximize the control and exploitation of Black Chicagoans. Driven by material interests, primarily, and inextricably tied to America’s race-based hierarchy, hegemonic institutions confined and restricted Black space via discriminatory housing practices to ensure continued economic exploitation. To enforce the spatial barriers they had erected, hegemonic institutions weaponized the police force, using it to occupy and control Black space. This essay establishes theoretical background of internal colonialism and social production of space, …

Regenerative Tourism Model: Challenges Of Adapting Concepts From Natural Science To Tourism Industry, Asif Hussain, Marie Haley

Journal of Sustainability and Resilience

The study proposes a regenerative tourism model. The application of the natural science ideas of regeneration needs to be clarified before the tourism industry can adopt a regenerative tourism model. Without such clarification, there is a high risk of ‘green washing’ and inappropriate adaption of a regenerative model. The borrowing of natural science to industry and its application in social sciences confuse the essence of the true concept of regeneration. In a regenerative agriculture context restoring a holistic system that mimics nature and includes social and economic spheres contributes to improving the whole system. When a social system aims to …

Unraveling The Geographies Of The U.S. Public Education System: An Analysis Of Scale, Segregation, And Hegemony, Olivia Ildefonso

Dissertations, Theses, and Capstone Projects

Other than one or two studies that focus on specific state-wide systems of public education, there has been no accounting for how the U.S. public education system came about in relation to space and scale. My dissertation research seeks to fill in this gap. Through focusing on the development of public education in the North and the South, I provide a foundation for understanding the grounded and contested processes of scale production that largely determined the U.S. public education system’s design and function.

In each of the seven chapters, I detail how fights over the structure and purpose of public …

Past-Futures Of Harlem: Black Urban Space At The Limits Of Spatial Justice, Dane C. Ruffin

Dissertations, Theses, and Capstone Projects

The racial capitalist development of the U.S. metropolitan landscape has been shaped by the involuntary displacement and dispersal of Black communities. From the dispossession of the Half-Free Negro Lots around the Fresh Collect pond in the seventeenth century to the clearing of Seneca Village to build Central Park in the nineteenth century to the turn of the twentieth-century police-facilitated “race riot” in the Tenderloin district of Manhattan, which fueled the move to Harlem, the four-hundred year history of Black Manhattan alone provides substantial evidence of this and is in no way unique in this regard. Incomplete, yet ongoing, is what …

A Comparison Of Sporadic-E Occurrence Rates Using Gps Radio Occultation And Ionosonde Measurements, Rodney Carmona, Omar A. Nava, Eugene V. Dao, Daniel J. Emmons

Faculty Publications

Sporadic-E (E_s) occurrence rates from Global Position Satellite radio occultation (GPS-RO) measurements have shown to vary by a factor of five between studies, motivating the need for a comparison with ground-based measurements. In an attempt to find accurate GPS-RO techniques for detecting E_s formation, occurrence rates derived using five previously developed GPS-RO techniques are compared to ionosonde measurements over an eight-year period from 2010–2017. GPS-RO measurements within 170 km of a ionosonde site are used to calculate E_s occurrence rates and compared to the ground-truth ionosonde measurements. The techniques are compared individually for each ionosonde site …

Drivers And Distribution Of Solar Pv In New York State, Jessica Stretton

Theses and Dissertations

This paper investigates the drivers and distribution of solar photovoltaic (PV) installations in New York State using statistical analysis and GIS. Rooftop residential solar projects were found across the state but were most heavily concentrated around the cities of New York, Schenectady and Ithaca. Larger scale, ground-mounted projects were located upstate and the less densely populated areas of the Lower Hudson Valley. Although there were more projects and kW generation downstate, individual solar PV installations were more likely to be larger in size upstate.
