Media witnessing and storytelling for environmental justice (EJ) provide an avenue to understand the relationships between “multiple realities of environmental injury” and to analyze “fleeting phenomena with lasting form; thereby transforming phenomena that are experienced in a plurality of lives into publicly recognized history” (Houston, 2012, 419, 422). This creates opportunities to challenge and eradicate the oppressive structures that deem certain individuals and groups disposable and ultimately protect the possessive investment in whiteness. Therefore, for the purposes of EJ, media witnessing creates space for dynamic, citizen-based storytelling which can undermine narratives that promote the life versus economy framework that has perpetuated oppression, injustice, and state sanctioned violence. Media witnessing in an EJ context demonstrates the potential for collective understanding and action, political opportunities, and healing.<br/>This paper is an analysis of the process of media witnessing in regards to the Flint Water Crisis and the construction of the Dakota Access Pipeline (DAPL) and will apply an EJ lens to this phenomenon. It will discuss how media witnessing in response to these two crises can be used as a precedent for understanding and utilizing this framework and digital storytelling to address the crises of 2020, primarily the COVID-19 pandemic and racial injustice. It will then examine how the intersectionality of race, gender, and age has implications for future media witnessing and storytelling in the context of EJ movements. Finally, it will explain how media witnessing can motivate holistic policymaking in the favor of EJ initiatives and the health and wellbeing of all Americans, as well as how such policymaking and initiatives must acknowledge the double-edged sword that is social media.

Environmental hazards and disaster researchers have demonstrated strong associations between sociodemographic indicators, such as age and socio-economic status (SES), and hazard exposures and health outcomes for individuals and in certain communities. At the same time, behavioral health and risk communications research has examined how individual psychology influences adaptive strategies and behaviors in the face of hazards. However, at present, we do not understand the explanatory mechanisms that explain relationships between larger scale social structure, individual psychology, and specific behaviors that may attenuate or amplify risk. Extreme heat presents growing risks in a rapidly warming and urbanizing world. This dissertation examines the social and behavioral mechanisms that may explain inequitable health outcomes from exposure to concurrent extreme heat and electrical power failure in Phoenix, AZ and extreme heat in Detroit, MI. Exploratory analysis of 163 surveys in Phoenix, AZ showed that age, gender, and respondent’s racialized group identity did not relate to thermal discomfort and self-reported heat illness, which were only predicted by SES (StdB = -0.52, p < 0.01). Of the explanatory mechanisms tested in the study, only relative air conditioning intensity and thermal discomfort explained self-reported heat illness. Thermal discomfort was tested as both a mechanism and outcome measure. Content analysis of 40 semi-structured interviews in Phoenix, AZ revealed that social vulnerability was associated with an increase in perceived hazard severity (StdB = 0.44, p < 0.01), a decrease in perceived adaptation efficacy (StdB = -0.38, p = 0.02), and an indirect increase (through adaptive efficacy) in maladaptive intentions (StdB = 0.18, p = 0.01). Structural equation modeling of 244 surveys in Phoenix, AZ and Detroit, MI revealed that relationships between previous heat illness experience, perceived heat risk, and adaptive intentions were significantly moderated by adaptive capacity: high adaptive capacity households were more likely to undertake adaptive behaviors, and those decisions were more heavily influenced by risk perceptions and previous experiences. However, high adaptive capacity households had lower risk perceptions and fewer heat illness experiences than low adaptive capacity households. A better understanding of the mechanisms that produce social vulnerability can facilitate more salient risk messaging and more targeted public health interventions. For example, public health risk messaging that provides information on the efficacy of specific adaptations may be more likely to motivate self-protective action, and ultimately protect populations.
