Climate change-related vulnerabilities in Loíza are prevalent in both physical and social dimensions. The social-ecological systems indicate that a change in one component will trigger an effect in the other regardless if physical or not, suggesting that the examination of vulnerabilities cannot be done overlooking one dimension. Such is the case of transportation, as climate change vulnerabilities in Puerto Rico are exacerbated due to the capacity of the Island to recover from a disaster, mainly because there are nearly no options for mobility aside from a private vehicle. This research intended to describe the social vulnerabilities of the population and asses the physical vulnerabilities of the transportation infrastructure of Loíza to understand how resilience is threatened using the social-ecological systems approach. This study found that the transportation infrastructure is exposed and sensitive to sea level rise, flooding, and strong winds, mainly because these climate stressors cause damage to the roadways and inhibit the flow and traffic of people throughout the main roadway and evacuation route, the PR-187. The study also identified that Loíza is socially vulnerable. Many people belong to one of the described vulnerable groups, indicating that its population may experience hurdles in preparing for and recovering after a natural disaster primarily because the available resources greatly condition the level of preparedness and capacity to cope. It was evidenced that transportation plays an enormous role in decreasing or increasing resilience in Loíza, as it will determine how fast people can access supplies and necessary services to reconstruct and recover from a natural disaster. Adaptation strategies should be outlined alongside the community to ensure an equitable and inclusive approach, as well as ensure assertive and effective outcomes for all the residents of Loíza. / Master of Urban and Regional Planning / Climate change-related vulnerabilities in Loíza are presented in both physical and social aspects. The social-ecological systems indicate that a change in one thing will trigger an effect in the other regardless if physical or not, suggesting that the study of vulnerabilities cannot be done overlooking one aspect. Such is the case of transportation, as climate change vulnerabilities in Puerto Rico are aggravated due to the capacity of the Island to recover from a natural disaster, mainly because there are nearly no options to move around other than an automobile. This research intended to describe the social vulnerabilities of the population and asses the physical vulnerabilities of the transportation infrastructure of Loíza to understand how resilience is threatened using the social-ecological systems approach. This study found that the transportation infrastructure is exposed and sensitive to sea level rise, flooding, and strong winds, mainly because these climate stressors cause damage to the roadways and stop the flow and traffic of people throughout the main roadway and evacuation route, the PR-187. The study also identified that Loíza is socially vulnerable.
