The Philippines is one of the most vulnerable archipelagic low–middle-income countries in regard to the impacts of climate change. Consequently, Puerto Princesa City, a coastal city in central Palawan, Philippines, faces the challenges of these impacts, which affect the food security of its coastal communities. This research presents an assessment of perceived climate changes and investigates their impact on food security. The research employed descriptive analysis to assess the perception of the residents towards climate change and its impacts, and multiple linear regression to examine the connections between climate change indicators and the fundamental components of food security within coastal communities. The results revealed that most participants (94%) believe climate change is happening, and many (71%) acknowledged this as anthropogenic. There are observations of sea level rise (76%), wave intensity (69%), warmer sea surface temperature (73%), and more frequent and stronger rainfall (72%) in comparison to 10 years ago. Coastal communities have become less food secure. Sea level rise was significantly associated with decreased food availability, access and stability (p < 0.05). Participants’ perception of extreme rainfall events and increased sea surface temperatures were associated with reduced food utilisation, leading to increased exposure to infectious diseases, pollution along the shores, and decreased fish growth and stock in the usual fishing spots (p < 0.05). This study provides valuable insights into the perceptions of climate change and its impacts on food security in coastal communities and highlights the necessity to understand food security in the Philippines and other low–middle-income countries vis-à-vis climate change and integrate holistic measures into the local and national agenda to mitigate the associated risks.
