👉 The Aaren is a type of ancient agricultural system that originated in Africa and was widely practiced there from the 3rd millennium BCE until the 1st millennium CE. The Aaren involved the cultivation of crops such as maize, millet, sorghum, and cassava, which were grown in fields that were raised on sturdy stumps or bamboo frames. The system was often combined with other agricultural practices such as animal husbandry, livestock care, and irrigation.
