Motivated by the need for cities to prepare and be resilient to unpredictable future weather conditions, this dissertation advances a novel infrastructure development theory of “safe-to-fail” to increase the adaptive capacity of cities to climate change. Current infrastructure development is primarily reliant on identifying probable risks to engineered systems and making infrastructure reliable to maintain its function up to a designed system capacity. However, alterations happening in the earth system (e.g., atmosphere, oceans, land, and ice) and in human systems (e.g., greenhouse gas emission, population, land-use, technology, and natural resource use) are increasing the uncertainties in weather predictions and risk calculations and making it difficult for engineered infrastructure to maintain intended design thresholds in non-stationary future. This dissertation presents a new way to develop safe-to-fail infrastructure that departs from the current practice of risk calculation and is able to manage failure consequences when unpredicted risks overwhelm engineered systems.
This dissertation 1) defines infrastructure failure, refines existing safe-to-fail theory, and compares decision considerations for safe-to-fail vs. fail-safe infrastructure development under non-stationary climate; 2) suggests an approach to integrate the estimation of infrastructure failure impacts with extreme weather risks; 3) provides a decision tool to implement resilience strategies into safe-to-fail infrastructure development; and, 4) recognizes diverse perspectives for adopting safe-to-fail theory into practice in various decision contexts.
Overall, this dissertation advances safe-to-fail theory to help guide climate adaptation decisions that consider infrastructure failure and their consequences. The results of this dissertation demonstrate an emerging need for stakeholders, including policy makers, planners, engineers, and community members, to understand an impending “infrastructure trolley problem”, where the adaptive capacity of some regions is improved at the expense of others. Safe-to-fail further engages stakeholders to bring their knowledge into the prioritization of various failure costs based on their institutional, regional, financial, and social capacity to withstand failures. This approach connects to sustainability, where city practitioners deliberately think of and include the future cost of social, environmental and economic attributes in planning and decision-making.
The availability of cooled space, whether public or private, has been shown to greatly reduce health risks associated with extreme heat. However, a lack of fine-scale knowledge of which households have access to this infrastructure results in an incomplete understanding of the health risks associated with heat. This knowledge gap could result in the misallocation of resources intended to mitigate negative health impacts associated with heat exposure. Additionally, when discussing accessibility to public cooled space there are underlying questions of mobility and mode choice. In addition to captive riders, a growing emphasis on walking, biking and public transit will likely expose additional choice riders to extreme temperatures and compound existing vulnerabilities to heat.
The application of Toni Morrison’s Beloved as a lens through which one can analyze intergenerational trauma on an individual and communal level results in a blueprint towards a remedial process. The characters and their experiences in her novel are representative of a myriad of ways in which trauma is manifested. I have broken down the concept of intergenerational trauma into the idea that it can be seen as the state where one is both simultaneously “falling” and “fallen” at the same time. Used here, the term “falling” refers to the consistent, individual trauma that one is experiencing. On the other hand, the term “fallen” refers to the trauma that a community as a whole has experienced and internalized. This framework that I establish based off of Beloved is a launching point for the conversation surrounding the topic of remedial actions in relation to intergenerational trauma that resulted from slavery. Using it as a basis of knowledge allows one to truly gather the weight of the situation regarding trauma postbellum. Considering the current climate surrounding any meaningful dialogue, knowledge is one of the most important aspects. Along with the concepts of “falling”/”fallen,” I also coined the term productive memory, which refers to the act of confrontation as well as the remembering of intergenerational trauma. The use of productive memory is imperative in addressing the prior ideas presented regarding intergenerational trauma and the possible pathways to move forward.
The work is based in anxieties, but its media influences are a strong indicator of tone and concept. At the very least, they helped me articulate why I wanted to work on a graphic novel on a post-climate change Sonoran. This desert that I’ve grown used to will change irrevocably, but it will be a new frontier to explore while the old will become a loss to mourn. This cycle of change is something I want to highlight in my work: we can worry, mourn, and fear, but there’s going to be something new.
New Sonoran is a graphic novel based upon the journey of Sage, a cartographer and anthropologist who travels the desert, annotating maps and studying a desert irrevocably affected by global climate change. As she catalogues the changes and losses in this new landscape, she learns how residents have adapted, and how people may still relate to the land.
