Arab Agricultural Revolution

 

The Arab Agricultural Revolution is a well-known revolution. Some refer to this phenomenon as the "Medieval Green Revolution," the "Muslim Agricultural Revolution," the "Islamic Agricultural Revolution," or the "Islamic Green Revolution." It took place during the Islamic Golden Age, spanning from the 8th to the 13th century CE.

This era saw the dissemination of numerous crop and agricultural techniques across various parts of the Islamic world, as well as the adaptation of crops and methods both from and to regions beyond it. Crops such as sorghum (from Africa), citrus fruits (from China), and mangoes, rice, cotton, and sugarcane (from India) were introduced to Muslim populations. A globalization of crops occurred, with many African and Chinese varieties being cultivated in Arab territories for the first time.

Technologies developed during this period included cash cropping and crop rotation systems. Practices such as double-cropping wheat in Yemen and cultivating rice in Iraq became possible. Agricultural development driven by research led to the implementation of crop rotation, irrigation improvements, and the use of crop varieties tailored to specific seasonal conditions, soil types, and water requirements. Selective breeding of livestock was also practiced.

By the early 9th century, modern agriculture had come to dominate the Arab economy, superseding the Roman model. The revolution rested on four pillars: irrigation systems, cultivation technologies, agrarian relations systems, and the introduction of diverse new crop varieties. Economic and social reforms also took place; notably, a transformation in land ownership occurred, allowing individuals—regardless of gender, tribe, or religion—to purchase and own land. Cooperative contracts across various business sectors also emerged. Public life expectancy improved thanks to the development of diverse food crops, vegetables, fruits, plantations, and livestock farming.

During this period, sugar cultivation was refined and transformed into a large-scale industry by the Arabs. Arabs and Berbers spread sugar cultivation throughout Arab territories starting in the 8th century. Many other agricultural innovations were introduced, such as new forms of land tenure and various irrigation techniques. ...gravity, sugar mills, the introduction of iron tools, and processing machinery.

Many agricultural experts emerged during this period. For instance, the botanist Abu al-Abbas al-Nabati developed techniques for testing, describing, and identifying plants. Works by the biologist Ibn Wahshiyya—such as *Al-Asma’i*—were translated into titles including *Book of Distinction*, *Book of Wild Animals*, *Book of the Horse*, and *Book of the Sheep*. Muslim agricultural experts advanced fields such as agronomy, meteorology, climatology, hydrology, soil utilization, and the management of agricultural enterprises, as well as pedology, agricultural ecology, irrigation, soil preparation, planting, manuring, weed control, sowing, tree felling, grafting, vine pruning, prophylaxis, phytotherapy, the care and improvement of microbiological cultures and plants, and crop harvesting and storage. There was also the agronomist Ibn Wahshiyya, whose technological innovations enabled the lifting of river water using various techniques.

The body of knowledge known as *The Nabatean Agriculture* advanced various agricultural sciences, including farm management, weather forecasting, the correlation of rainfall data with solar positioning and wind patterns, and the fundamentals of plant tissue culture. Soil properties, composition, and the use of manure are detailed in the book by Ibn al-‘Awwam, which describes 585 microbiological cultures—55 of which relate to fruit plants. This book was translated into Spanish by Banqueri in 1801 and into French by Clément-Mullet in Paris in 1864.

Astronomy was also effectively applied to agriculture and botany—specifically for forecasting the climate, tracking time, and creating calendars that dictated when to plant seasonal crops, prune trees, fertilize, and harvest. These calendars even advised on what foods should be consumed or avoided during different seasons.

Al-Dinawari’s *Book of Plants* (*Kitab al-Nabat*) illustrates the application of astronomy and meteorology to agriculture. A 9th-century botanist, Al-Dinawari is considered the founder of Arab botany; his encyclopedia describes 637 plant species and details their developmental stages—from germination to death—as well as the production of flowers and fruit. In the early 13th century, Ibn al-Baitar authored *Kitab al-Jami fi al-Adwiya al-Mufrada*, the most comprehensive botanical compilation and encyclopedia of medicinal plants of its time. It cataloged 1,400 different plants, foods, and medicines, including 300 species he had discovered himself. This work became a foundational text for the development of European agriculture.
