The three sustainable indigenous knowledge practice includes
1. Agroforestry knowledge
2. Agricultural farming knowledge
3. Hinting and gathering knowledge
1. Agroforestry
It involves planting and conserving trees together with crops in the same land, this system of farming help to control the environmental temperature, protect some crops from direct sunlight, and also prevent crops from being destroyed by wind, hails, and heavy rains. Furthermore, the forests help to improve soil quality, reduce soil erosion, and storing carbon as well as providing wild food, firewood, timber, and herbal medicine among others.
2. Agricultural farming.
It involves different forms of planting crops without the use of chemicals. The indigenous people used farming methods such as rotation farming and intercropping. Rotational farming is where farmers plant different crops on the same land in different seasons. While intercropping is where farmers sow more than two crops in the same land at the same season to minimize land use and reduce the risks of loss in case a single crop fails to produce expected outcomes. These indigenous agricultural practices helped preserve the productivity potentials of the soil, minimize the attack of pests and diseases, to build a good soil structure, and improve the capacity to store carbon on the plantation.
3. Hunting and gathering
It involves the system where people largely depend on wild foods for survival and not growing crops and rearing animals. These include hunting wild animals, fishing, a gathering wild plants for food such as fruits, vegetables, seeds, nuts, among others. Therefore the indigenous people had knowledge of combining meat, fruits, vegetables, seeds fish, insects, and others to ensure they get a balanced diet.
