The Roots of Agriculture in Southern Arabia (RASA) team (1998 – 2008) led by editors Joy McCorriston (PI) and Michael Harrower (Field Manager), has published a monograph summarizing the research findings of the ten-year-long AIYS and NSF-funded project based in the Wadi Sana region of southeastern Yemen. The monograph presents the field data, archival photographs and analysis results (such as the Bayesian analysis of the geomorphological and settlement chronology of the wadi) collected by the team. The research was focused on documenting the initiation and development of pastoral societies in the region, primarily over the Early – Middle Holocene (10kya – 7kya BP).
