This research explores the linkages between threat perception and adaptive behaviour in the face of climate change in Galle, Sri Lanka. We use an analytical framework to analyse the complexity of aspiration versus adaptive practices, centring around the synthesis of threat perception, vulnerability, adaptive capacity and livelihood resilience. Our findings reveal that individual threat perception incentivises climate adaptation strategies, bolstering livelihood resilience. However, unfavourable societal circumstances affecting the participants significantly impede the implementation of these resilience strategies. In addition to a knowledge gap and lack of climate change awareness in popular discourse, we observe a conspicuous discrepancy between individual aspirations and adaptive capacity with the ongoing economic crisis and the need for governmental climate legislation at the time of research. This research, therefore, emphasises a nuanced approach to researching climate change adaptation, considering the gravity of societal circumstances that delimit how individuals can engage in livelihood resilience strategies.
