“…The clearest archaeobotanical evidence for IGR plants comes from outside the Mediterranean in the Red Sea port of Quseir al-Qadim where taro, sugarcane, aubergine, lime, banana and a new cultivar of watermelon were introduced in the eleventh–thirteenth centuries, while other crops such as sorghum, cotton, pearl millet, citrus fruits and rice became more extensively cultivated during this period (Van der Veen 2010). While some of these crops were cultivated in the Roman and Late Antique periods in zones such as the irrigated oases of Fazzan in south-western Libya (Pelling 2008), growing archaeological evidence for IGR plants points to their first appearance during the Middle Ages, including Israel (Jerusalem; Fuks et al 2020), Spain (Ilbira and Tortosa; Alonso et al 2014; Peña-Chocarro et al 2019), Sicily (Mazara del Vallo; Carver & Molinari 2020: 143) and Morocco (Volubilis; Fuller & Pelling 2018; Figure 1). Yet, despite Van der Veen's (2010) call to broaden the categories of agricultural innovations incorporated into the IGR model to include animals, growing conditions, tools and management practices, environmental archaeologists have refined their methods (Fuks et al 2020) but remained largely focused on phytogeography, or the timing and diffusion of IGR crops.…”
