Description: This study presents a comprehensive paleoenvironmental reconstruction of the Byzantine and Early Islamic western Negev D esert communities during the 4th-8th centuries CE. The study is based on 33 pollen samples and hundreds of charcoal remains that were recovered from the villages of Shivta and Nitzana. The results demonstrate that during the 5–6th centuries CE flourishing desert agricultural communities existed on the periphery of the Byzantine Empire (Eastern Roman Empire). The presence of diverse fruit-tree horticulture is revealed by both pollen and charcoal remains (grape, fig, olive, carob, almond/apricot, pomegranate, date palm and the exotic hazelnut). The rich botanical assemblages also provide evidence of the cultivation by irrigation of conifers and other Mediterranean trees common to the more humid Mediterranean vegetation zone, including the prestigious cedar of Lebanon. The palynological reconstruction of an ornamental garden at Shivta indicates the ability to invest water and labor, not only for horticultural and construction purposes, but also for ornamental greenery. We therefore suggest that the Byzantine Negev Desert community was a luxury society in contrast to societies living in a mode of survival in challenging desert environments. During the Early Islamic period (since the second half of the 7th century CE), our data show a dramatic decline in fruit-tree horticulture coupled with indicators signifying overexploitation for fuel of the nearby natural woody desert environment. Hence, we claim that in addition to previous possible explanations for the demise of the Negev Byzantine communities (plague pandemic, climate change, the Muslim conquest), overexploitation of the natural vegetation should also be taken into account. This study therefore helps address historical questions that are also pertinent to the modern era, regarding the existence of flourishing societies in challenging environments, overexploitation of the natural environment, and neglect of sustainability. © 2020 Elsevier Ltd and INQUA
