About

GeoArches treats coastal and deltaic landscapes as natural laboratories to understand how societies historically adapted to dynamic environments. By integrating archaeological excavation, sediment coring, isotopic and elemental geochemistry, remote sensing, and GIS analyses, we reconstruct long-term trajectories of resource production, innovation, and ecological adaptation. Crucially, our interdisciplinary approach connects these landscape histories to the social institutions—legal, economic, and ritual—that both shaped and were shaped by them. Today, many of these culturally rich landscapes are rapidly disappearing due to sea-level rise and urban expansion. GeoArches aims to document and interpret this threatened cultural-ecological record, providing actionable insights for decision-makers, descendant communities, and conservation practitioners.
