Now here’s a terrific resource, a really reliable site dedicated to medieval Arabic manuals on farming produced all over the medieval Islamic world (see map above) . You probably already know but the medieval Islamic states transformed agriculture from Spain to parts of India, from the Sahel to Sicily.
The purpose of the Filāḥa Texts Project is to publicise and elucidate the written works collectively known as the Kutub al-Filāḥa or ‘Books of Husbandry’ compiled by Arab, especially Andalusi, agronomists mainly between the 10th and 14th centuries (see Authors & Works). These systematic and detailed manuals of agriculture, horticulture and animal husbandry have been sadly neglected and remain largely unknown in the Anglophone world – apart from some of the Yemeni works they have never been translated into English.
Edit. Some more thoughts on this. I think the title should really be “How Medieval Islam Transformed Food and How it Had to Transform Farming to get the Foodstuffs it Needed.”
Also, I had the pleasure of taking Expiración Garcia, mentioned on this site as one of the premier researchers in the area, to lunch last year when she was giving a series of seminars in the UNAM (National Autonomous University of Mexico). She is a meticulous researcher. But neither I nor any of the other members of the seminar could persuade her to speculate on the clear transfer of much of this agronomy to Mexico. Too bad, if understandable given it was her first visit, the need to be circumspect about this kind of research in Spain, time pressure, etc.
