Description
This dissertation advances the capability of water infrastructure utilities to anticipate and adapt to vulnerabilities in their systems from temperature increase and interdependencies with other infrastructure systems. Impact assessment models of increased heat and interdependencies were developed which incorporate probability, spatial, temporal, and operational information. Key findings from the models are that with increased heat the increased likelihood of water quality non-compliances is particularly concerning, the anticipated increases in different hardware components generate different levels of concern starting with iron pipes, then pumps, and then PVC pipes, the effects of temperature increase on hardware components and on service losses are non-linear due to spatial criticality of components, and that modeling spatial and operational complexity helps to identify potential pathways of failure propagation between infrastructure systems. Exploring different parameters of the models allowed for comparison of institutional strategies. Key findings are that either preventative maintenance or repair strategies can completely offset additional outages from increased temperatures though-- improved repair times reduce overall duration of outages more than preventative maintenance, and that coordinated strategies across utilities could be effective for mitigating vulnerability.

Description
As climate change accelerates worldwide, coastal communities face escalating threats, including sea level rise, saltwater intrusion, erosion, and flooding, jeopardizing their physical, economic, and cultural integrity. In the coastal community of Charlotteville, a non-profit organization called the Environmental Research Institute of Charlotteville (ERIC) is dedicated to creating a “mutually beneficial relationship between the coastal communities and ecosystems of North East Tobago”. Their work includes the training and staffing of Community-Based Field Technicians (CBFTs) - Charlotteville residents who have been trained by ERIC in their conservation work and practices and now work for the organization within their community. This research delves into the intricate relationship between cultural narratives and community resilience in Charlotteville, Tobago. Through targeted surveys of Charlotteville residents, ERIC, and CBFTs, this research explores how cultural traditions and conservation work can impact a community’s resilience to climate change. Initial findings suggest the profound significance of the sea to Charlotteville residents and potentially echo a collective desire to safeguard marine resources for future generations. Moreover, aligning conservation projects with immediate community needs and securing additional funding could potentially bolster resilience-building initiatives. The CBFTs emerge as a potentially crucial stakeholder, as survey data suggests that they facilitate communication, collaboration, and knowledge sharing between ERIC and the community. By beginning to illuminate the complex relationship between cultural heritage, environmental stewardship, and community resilience, this research offers potential insights for fostering resilience in coastal communities worldwide.
