This chapter is a critical review of Trinidad and Tobago social welfare systems preparedness for climate change in light of competing social pressures such as migration. Climate change exacerbates existing social, economic, and political vulnerabilities, driving people to leave their homes in search of better living conditions and opportunities. Climate change in the Caribbean has proliferated greenhouse gases from agriculture, livestock, landfills and contributed to the deforestation of green spaces which reduces the planet’s capacity to absorb carbon dioxide. There is also a rise in average temperatures (e.g., sea levels) which increases heatwaves, droughts, intense cyclones, and hurricanes with ocean warming leading to coastal erosion and inundation. The Venezuelan refugee crisis has strained Trinidad and Tobago by burdening the public and private sectors with increased need of services, causing physical overcrowding, and civil unrest between its citizens and migrants. This situation underlines the heightened social vulnerability in Trinidad and Tobago. This chapter examines social vulnerability of Trinidad and Tobago to climate change by utilizing three indicators of exposure, sensitivity, and adaptability. The findings indicate Trinidad and Tobago's preparedness for climate change involves a multifaceted approach, considering the dimension of exposure to climate-related hazards, sensitivity to these impacts, and the capacity to adapt and respond effectively.
