context_page_description: The Arab Agricultural Revolution is the transformation in agriculture from the 8th to the 13th century in the Islamic region of the Old World. The agronomic literature of the time, with major books by Ibn Bassal and Abū l-Khayr al-Ishbīlī, demonstrates the extensive diffusion of useful plants to Medieval Spain, and the growth in Islamic scientific knowledge of agriculture and horticulture. Medieval Arab historians and geographers described al-Andalus as a fertile and prosperous region with abundant water, full of fruit from trees such as the olive and pomegranate. Archaeological evidence demonstrates improvements in animal husbandry and in irrigation such as with the sakia water wheel. These changes made agriculture far more productive, supporting population growth, urbanisation, and increased stratification of society.
  The revolution was first described by the historian Antonio Garcia Maceira in 1876. The name was coined by the historian Andrew Watson in an influential but at the time controversial 1974 paper. However, 40 years on, it has proven useful to historians and has been supported by findings in archaeology and archaeobotany.
context_section_description: The first Arabic book on agronomy to reach al-Andalus, in the 10th century, was Ibn Wahshiyya's al-Filahat al-nabatiyya (Nabatean Agriculture), from Iraq; it was followed by texts written in al-Andalus, such as the Mukhtasar kitab al-filaha (Abridged Book of Agriculture) by Al-Zahrawi (Abulcasis) from Cordoba, around 1000 AD.
  The eleventh century agronomist Ibn Bassal of Toledo described 177 species in his Dīwān al-filāha (The Court of Agriculture). Ibn Bassal had travelled widely across the Islamic world, returning with a detailed knowledge of agronomy. His practical and systematic book both gives detailed descriptions of useful plants including leaf and root vegetables, herbs, spices and trees, and explains how to propagate and care for them.
  The twelfth century agronomist Abū l-Khayr al-Ishbīlī of Seville described in detail in his Kitāb al-Filāha (Treatise on Agriculture) how olive trees should be grown, grafted (with an account of his own experiments), treated for disease, and harvested, and gave similar detail for crops such as cotton.
  Medieval Islamic agronomists including Ibn Bassal and Abū l-Khayr described agricultural and horticultural techniques including how to propagate the olive and the date palm, crop rotation of flax with wheat or barley, and companion planting of grape and olive. These books demonstrate the importance of agriculture both as a traditional practice and as a scholarly science. In al-Andalus, there is evidence that the almanacs and manuals of agronomy helped to catalyse change, causing scholars to seek out new kinds of vegetable and fruit, and to carry out experiments in botany; in turn, these helped to improve actual practice in the region's agriculture. During the 11th century Abbadid dynasty in Seville, the sultan took a personal interest in fruit production, discovering from a peasant the method he had used to grow some exceptionally large melons—pinching off all but ten of the buds, and using wooden props to hold the stems off the ground.
