This research employs archaeobotanical and biomolecular methods to reconstruct ancient agropastoral change over the first millennium CE in two microregions, the Aravah valley along the southern border of modern Israel-Jordan and the adjacent Negev Highlands. The region witnessed unprecedented agricultural developments during this period, alongside major socio-political, climatic, and environmental changes – including climate change and plague. Rich and well-preserved organic remains from rubbish dumps at nine archaeological sites will provide the basis for this study.
