The strength of construction material is a crucial consideration in the process of structural design and construction. Conventional materials such as concrete or steel have been widely utilized due to their predictable material performance. However, a significant obstacle to the widespread use of bamboo in structural elements lies in the challenge of its standardization. Many previous research studies have explored bamboo’s load bearing capacity, but the information remains limited due to variations in species, size, age, physical properties, moisture content, and other factors, making it difficult to predict their load-bearing capacity. This study aims to propose Artificial Neural Network (ANN) …

Experiences With Environmental Gentrification: Evidence From Chicago, Tania Schusler, Amy Krings, Richard T. Melstrom

School of Environmental Sustainability: Faculty Publications and Other Works

Environmental contamination and limited access to green spaces disproportionately burden communities of color with negative impacts on residents’ health. Yet, cleaning up contamination and creating green spaces has in some cases been associated with displacing long-term residents as the neighborhood becomes desirable to more affluent, often Whiter, populations through environmental gentrification. We used mixed methods to investigate environmental gentrification in the city of Chicago, IL, USA. We examined quantitatively the relationship between green areas, brownfield cleanups, and indicators of gentrification, including race and ethnicity, income, households without children, and home ownership. We explored through qualitative interviews how key informants perceive …

College Student Food Security During The Covid-19 Pandemic, Frances Rafferty, Tania Schusler, Mariana Valencia Mestre

School of Environmental Sustainability: Faculty Publications and Other Works

Food insecurity among college and university students has increased in the past decade. The COVID-19 pandemic has presented unique public health challenges, including increased food insecurity. In a cross-sectional survey of students at a private university in the midwestern U.S. (N=253) we examined how student food security status changed during the pandemic and what relation-ships exist between changes in food security and various aspects of student identities. Twenty-nine percent of responding students indicated that they became less food secure during the pandemic, and the overall reported food insecurity rate increased by 130.77%. Change in respondent food security status during the …

Connectivity And Racial Equity In Responding To Covid-19 Impacts In The Chicago Regional Food System, Rowan Obach, Tania Schusler, Paulina Vaca, Sydney Durkin, Ma'raj Sheikh

School of Environmental Sustainability: Faculty Publications and Other Works

The COVID-19 outbreak led to major disruptions in food systems across the globe. In the United States’ Chicago region, the outbreak created immediate concerns around increased hunger, food insecurity, supply chain disruptions, and loss of local livelihoods. This was especially evident in communities of color, which faced disproportionate impacts from the pandemic. In March 2020, the Chicago Food Policy Action Council (CFPAC) coordinated a Rapid Response Effort that convened people in working groups related to emergency food assistance, local food producers, small businesses, and food system workers to address urgent needs that arose due to the pandemic. Each working group …

Reclaiming The Food System: Learning From Community Responses To The Impacts Of Covid-19, Tania Schusler

School of Environmental Sustainability: Faculty Publications and Other Works

The dominant food system is racially and economically unjust, environmentally unsustainable, and vulnerable to shocks, such as the COVID-19 pandemic. This research explored how non-profit organizations in the Chicago region who responded to increased food insecurity and other pandemic impacts are opening pathways to re-organize the food system towards racial equity and resilience to future shocks. Workshops held in 2022 brought together 26 individuals from 20 non-profit organizations in the Chicago region with majority people of color across their leadership, staff, and board. This report summarizes participants’ descriptions of how their organizations pivoted in response to the pandemic’s impacts and …

Determination Of The Ecological Water Quality In The Orienco Stream Using Benthic Macroinvertebrates In The Northern Ecuadorian Amazon, Federico Sinche, Manuel Cabrera, Lenin Vaca, Edin Segura, Pablo Carrera

School of Environmental Sustainability: Faculty Publications and Other Works

In recent years, pollution of watercourses in nearby protected ecosystems has increased due to urbanization. Standard physiochemical methods and probes are one way to monitor watercourses for quality. However, they often do not provide the full ecological status of the body of water. In this work, we set out to assess the ecological water quality of an urban stream by using benthic macroinvertebrates as bioindicators. We conducted the work on the Orienco stream in Lago Agrio in the province of Sucumbíos in the Northern Ecuadorian Amazon (NEA). The stream has become a sink of raw domestic sanitary wastewater from rural …

This research sheds light on perceptions of environmental gentrification in Chicago. It also identifies policies and practices that hold potential to promote environmentally healthy neighborhoods and equitable development without displacement.

Executive Summary

Purpose

Access to greenspace, clean air, water, food, and safe, affordable, and stable housing are all important to good health. Yet, low income and communities of color endure disproportionate pollution burdens that negatively affect health. While cleaning up contamination or implementing “green” improvements like parks, playgrounds, bike trails, and other greenspaces can reduce health disparities, these environmental improvements sometimes contribute to rising rents and property values, which can …

In Search Of Environmental Sustainability At The Base Of The Pyramid, Mark Heuer, Nancy E. Landrum

School of Environmental Sustainability: Faculty Publications and Other Works

This paper proposes a revision to Hart and Sharma’s 2004 model for corporate engagement with the base of the pyramid (BoP) by making the BoP community and the natural environment, not the firm, the central focus for engagement. The revised model proposes that core stakeholders must include the BoP community, the poor, weak, and illiterate, as they can benefit most from the community collective action model presented herein to address sustainability in the natural environment. These are the core stakeholders rather than fringe stakeholders, as indicated in the Hart and Sharma model. Our model recognizes the legitimacy of the firm …

Ozone Variability In The Midlatitude Upper Troposphere And Lower Stratosphere Diagnosed From A Monthly Sage Ii Climatology Relative To The Tropopause, Pi-Huan Wang, Derek M. Cunnold, Charles R. Trepte, Hsiang J. Wang, Ping Jing

School of Environmental Sustainability: Faculty Publications and Other Works

[1] A midlatitude (25°–65°) monthly zonal median ozone climatology in the upper troposphere and lower stratosphere (UTLS), from 8 to 20 km with a 0.5-km vertical resolution and a 5° latitudinal resolution, is developed on the basis of version 6.2 (V6.2) ozone profile retrievals from the Stratospheric Aerosol and Gas Experiment (SAGE) II measurements from October 1984 to August 2005. To avoid mixing of the tropospheric ozone data with stratospheric values, the thermal tropopause height is used as a base altitude for developing the climatology (the monthly mean tropopause height has been added back to the climatological profile). This feature …

School of Environmental Sustainability: Faculty Publications and Other Works

[1] Ozone columns below 147 hPa are derived over the United States from September 2004 to August 2005 from the differences between clear-sky Aura OMI columns and coincident MLS columns. The mean difference from coincident ozonesonde measurements at four USA sites is 0.3 DU with an rms difference of 10.1 DU and a correlation coefficient of 0.67. Semimonthly patterns of the columns over the USA for the summer of 2005 have been produced. The observed columns, as well as Regional Air Quality Forecast (RAQAST) model columns, show high values over the southeastern USA and its surrounding oceans. Changes of these …

Influence Of Isentropic Mixing On Seasonal Ozone Variations In The Lower Stratosphere And Upper Troposphere, Ping Jing, Derek M. Cunnold, Es Yang, Hj Wang

School of Environmental Sustainability: Faculty Publications and Other Works

[1] The isentropic cross-tropopause ozone transport has been estimated in both hemispheres in 1999 based on the potential vorticity mapping of Stratospheric Aerosol and Gas Experiment II ozone measurements and contour advection calculations using the NASA Goddard Space Flight Center Global and Modeling Assimilation Office analysis. The estimated net isentropic stratosphere-to-troposphere ozone flux is ∼118 ± 61 × 10⁹ kg yr⁻¹ globally within the layer between 330 and 370 K in 1999; 60% of it is found in the Northern Hemisphere, and 40% is found in the Southern Hemisphere. The monthly average ozone fluxes are strongest in summer …
