It is believed that in Africa, agriculture started about 6000 years ago. The use of discovered tools and weapons led to the development of crop cultivation and domestication of animals. True plant domestication probably began when the weakest plant were rejected and only seeds from the strongest plants were set aside for re-sowing mainly yielding grasses (cereals) and the same applied to animal domestication.
After a through look into different agricultural practices that existed in Africa, it is equally paramount to know the contributions of technology to the development of agriculture in Africa;-
(a) The increased use of iron tools amongst the different societies of Africa, led to the increase of land for cultivation, which resulted into increased agricultural productivity. The food storage skills insured an insurance against loss of future crops through natural disasters such as drought or flood thus food supply throughout the year. Some communities whose soils easily exhausted developed the use of manure which renewed the land and thus increased production. The development and use of irrigation opened up the once un-cultivatable to be productive for agriculture once again.
(b) Not only did the technological improvement contribute to the development of agriculture but also the environment had the great bearing on the development of agriculture in Africa.
(c) The reliable rainfall supplemented with the fertile soils in given areas resulted in the development of permanent crop agriculture or cultivation accompanied with increased agricultural production.
(d) Pest free and disease free areas were suitable for both crop and animal husbandry, as they would attract settlement. Also in place is the availability of iron technology in given societies making it possible for the making of iron tools which advanced on the methods of production and thus increased productivity.
(e) It ensured man with reliable food supplies, The impacts of agricultural development are immeasurable as it ensured man with reliable food supplies, permanent settlement, labour specialization and surplus production and thus increase in population.
(f) Farming was not suitable in every environment, the disadvantage of settled farming may also have been apparent through farming could support a larger population; it left the people more exposed to the dangers of famine caused by natural disasters such as drought and floods
