Exploring The Potential Of Feature Selection Methods In The Classification Of Urban Trees Using Field Spectroscopy Data, Simbarashe Jombo, Elhadi Adam, Marcus J. Byrne, Khalid Adem Ali, Solomon W Newete
International Journal of Geospatial and Environmental Research
Mapping of vegetation at the species level using hyperspectral satellite data can be effective and accurate because of its high spectral and spatial resolutions that can detect detailed information of a target object. Its wide application, however, not only is restricted by its high cost and large data storage requirements, but its processing is also complicated by challenges of what is known as the Hughes effect. The Hughes effect is where classification accuracy decreases once the number of features or wavelengths passes a certain limit. This study aimed to explore the potential of feature selection methods in the classification of …
Scale Mis-Matches When Assessing Chloride Concentration And Corrosiveness Using Statewide Data For Trend Analysis, Rebecca L. Kauten
Scale Mis-Matches When Assessing Chloride Concentration And Corrosiveness Using Statewide Data For Trend Analysis, Rebecca L. Kauten
International Journal of Geospatial and Environmental Research
This study compares chloride concentrations and a series of corrosiveness indexes to determine whether trends in statewide databases appropriately detect local conditions. Chloride concentrations in local, urban streams generally persist at higher levels than what is typical of natural waters. Data collected for statewide water quality assessments are often at a broader geographical scale. Results and subsequent policies may indicate little to no environmental concern, meanwhile degradation at the local scale remains relatively undetected. Pulses of local snowmelt runoff may violate water quality criteria, but long-term trends measured at the statewide scale are in decline. Results highlight the need for …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft
Human–Wildlife Interactions
Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …
Advancing Best Practices For Aversion Conditioning (Humane Hazing) To Mitigate Human–Coyote Conflicts In Urban Areas, Lesley Sampson, Lauren Van Patter
Advancing Best Practices For Aversion Conditioning (Humane Hazing) To Mitigate Human–Coyote Conflicts In Urban Areas, Lesley Sampson, Lauren Van Patter
Human–Wildlife Interactions
Coyotes (Canis latrans) are now recognized as a permanent feature in urban environments across much of North America. Behavioral aversion conditioning, or humane hazing, is increasingly advocated as an effective and compassionate alternative to wildlife management strategies, such as trap and removal. Given a growing public interest in humane hazing, there is a need to synthesize the science regarding methods, outcomes, efficacy, and other relevant considerations to better manage human–coyote conflicts in urban areas. This paper was prepared as an outcome of a workshop held in July 2019 by Coyote Watch Canada (CWC) to synthesize the literature on …
A Neighborhood-Level Perspective Of Real Estate Determinants In Three U.S. Cities, Mikhail Samarin, Madhuri Sharma
A Neighborhood-Level Perspective Of Real Estate Determinants In Three U.S. Cities, Mikhail Samarin, Madhuri Sharma
International Journal of Geospatial and Environmental Research
This study examines the relationships between commonly available socio-economic and environmental determinants of real estate (crime, quality of schools, racial/ethnic diversity, and built environment) and real estate values in socially and politically recognized units in the three largest cities of the U.S.—New York, Los Angeles, and Chicago. Utilizing a variety of data sources used by potential real estate buyers, we conduct correlations, mapping, and multiple regression analyses to identify the degrees and strengths of associations between select determinants and real estate values at these politically recognized units. Results suggest that the cities exhibit similar patterns for crime-related characteristics and quality …
Triple Threat Gateway? Respiratory Health, Demographics And Land Use In Metro East St. Louis, Missouri-Illinois, Usa, Stacey R. Brown-Amilian
Triple Threat Gateway? Respiratory Health, Demographics And Land Use In Metro East St. Louis, Missouri-Illinois, Usa, Stacey R. Brown-Amilian
International Journal of Geospatial and Environmental Research
This paper examines a triple threat for residents of two counties in the St. Louis metropolitan area. Previous environmental justice research has focused on demographics and toxic facilities. This research builds upon those assessments by incorporating hospital discharge data and demographics as well as three different types of pollution sources. Air pollution monitors were unavailable to use during the time period of 2009-2011, therefore proxy measures of pollution in the form of major roadways, industrial land use parcels, and toxic facility information from the EPA Toxic Release Inventory are utilized. This study integrates both spatial coincidence and proximity analysis methods …
Green To Gray: Political Ecology Of Paving Over Green Spaces In Moscow, Russia, Mikhail S. Blinnikov, Liudmila Volkova
Green To Gray: Political Ecology Of Paving Over Green Spaces In Moscow, Russia, Mikhail S. Blinnikov, Liudmila Volkova
International Journal of Geospatial and Environmental Research
Moscow, Russia is the largest city in Europe with over 12.6 million residents. The remarkable fact is that it is also a biologically diverse ecosystem with a few dozen specially protected natural areas, including 15 large forest parks and a variety of smaller nature-places. The recent landscaping “improvements” conducted by the Moscow government since 2010 greatly increased negative impacts on the green infrastructure, e.g., a lot more paving, systematic grass mowing, widespread planting of exotic plant species, increased residential and commercial construction, more noise, etc. While quantification of the impacts of the above on the biota is not easy, we …
A Conceptual Agent-Based Model Of Farming Households’ Vulnerability To Winter Storms, Yiyi Zhang
A Conceptual Agent-Based Model Of Farming Households’ Vulnerability To Winter Storms, Yiyi Zhang
International Journal of Geospatial and Environmental Research
Vulnerability assessments are implemented to identify regions and groups at risk and factors that need to be addressed to reduce vulnerability. Existing assessments have allowed multidimensional factors to be examined in various settings and adopted complex models to simulate human-environment-weather interactions. However, these models are far less accessible than traditional models due to model abstraction and there has been limited research detailing a formalized way to simulate the interactions between rural households and external changes in response to a specific extreme weather event. To supplement applied efforts in vulnerability assessments and address the challenge in communicating agent-based models, this study …

Mapping And Describing Geospatial Data To Generalize Complex Models: The Case Of Littosim-Gen, Ahmed Laatabi, Nicolas Becu, Nicolas Marilleau, Cécilia Pignon-Mussaud, Marion Amalric, Xavier Bertin, Brice Anselme, Elise Beck
International Journal of Geospatial and Environmental Research
For some scientific questions, empirical data are essential to develop reliable simulation models. These data usually come from different sources with diverse and heterogeneous formats. The design of complex data-driven models is often shaped by the structure of the data available in research projects. Hence, applying such models to other case studies requires either to get similar data or to transform new data to fit the model inputs. It is the case of agent-based models (ABMs) that use advanced data structures such as Geographic Information Systems data. We faced this problem in the LittoSIM-GEN project when generalizing our participatory flooding …
Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou
Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou
International Journal of Geospatial and Environmental Research
This paper presents an exploratory spatial data analysis (ESDA) of road traffic crashes at different severity levels in West Virginia (WV). Although ESDA can support transportation safety decision-making by helping planners understand and summarize crash data, it is underutilized in practice. This paper describes the application of five representative easy-to-use method to identify crash patterns and high crash-risk counties in WV. Analysis of crash data from 2010 to 2015 indicated that traffic crashes in WV were not spatially correlated. However, crash severities were found to be positively correlated.
Ecosystem Services Of Urban Tree Canopy For The Mitigation Of Climate Change: Measuring Carbon Sequestration And Understory Temperature Reduction Of Knoxville’S Urban Forest, Tyler Hounshell
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
In the future, the city of Knoxville, Tennessee will be impacted by climate warming due to anthropogenic climate change. Yet, the ecosystem services provided by urban tree canopy in Knoxville’s urban forest can help mitigate the effects of climate warming. In addition to improving air quality, regulating water flow, and reducing noise pollution, Knoxville’s urban forest serves as a carbon sink and sequesters carbon dioxide on an annual basis. Utilizing methods for calculating carbon sequestration by trees in urban and suburban settings developed by the U.S. Energy Information Administration, the sequestration potential and its uncertainty is calculated until the year …

A Pilot Study On The Relationship Between Urban Green Spaces And Fine Particulate Matter, Sohyun Park, Seungman Kim, Jaehoon Lee
International Journal of Geospatial and Environmental Research
This study aims at identifying the relationships among various variables that influence city-wide PM2.5 pollution levels in the six largest cities in Texas. The variables were categorized into three groups for statistical analysis: 1) urban components (city land area, urban population, population density); 2) green space components (coverage, percentage, connectivity, and shape); and 3) meteorological factors (ambient temperature and wind speed). To identify the relationship between meteorological features and daily PM2.5 concentration, we used descriptive statistics for each city and all six cities combined. A bivariate statistical test was used to examine the correlation between urban and green …
