The Fars cultural zone, including the Kur River Basin, has been continuously inhabited throughout history, driving regional transformations. In contrast, peripheral areas like the Bavanat River Basin have been influenced by these central regions, reflecting broader socioenvironmental dynamics. Despite its small size (less than 70 km in length), the Bavanat River Basin features a diverse landscape, offering prehistoric communities various environmental opportunities and challenges. Studying settlements in this region can provide insights into societal resilience, settlement dynamics, and the factors contributing to societal collapse.This article presents research conducted in the Bavanat River Basin, including surveys and the excavation of the Neolithic site of Hormangan, to explore prehistoric cultural developments. Systematic field surveys were employed to identify archaeological sites from various periods, and surface materials and excavation findings were analyzed to understand human-environment interactions. The study investigates how climatic and social changes influenced settlement patterns. Key research questions include: What are the earliest traces of human settlement in the region? How did the Bavanat Valley interact with other regions? What were the cultural dynamics and transformations in prehistory? How did environmental and climatic factors affect settlement formation, resilience, and collapse?
