Between Land and Sea in Puerto Rico: Climates, Coastal Landscapes and Human Occupations in the Mid-Holocene Caribbean

The global effect of human-induced climate change is one of the most important issues governments worldwide have to address. This issue is especially serious for coastal communities due to the threat posed by sea level rise. This is especially relevant for the Caribbean Region, where an estimated 40 million people, about 70% of the population, live in densely populated coastal cities, towns and villages. Recent archaeological studies in different parts of the world have shown that this is not the first time in history humans have faced the need to respond to rapid changes in climate and environment, but the process of change and its effect on human societies in the Caribbean are poorly understood. This research considers the effect that Early to Mid-Holocene climate change on tropical coastal landscapes and the distribution of habitats within them, in order to understand the range of foraging decisions indicated by material remains in archaeological contexts, and study human resilience to changing conditions. A deep-time perspective of human-environment interaction in the Caribbean will facilitate a better understanding of the scope of human strategies that have led to either resilient or fragile socioeconomic systems in the face of crises.
