The Importance of Agroforestry Systems for Mitigation of Climate Change in Tropical Africa

Abstract

The most important agroforestry systems (AFS) in the region of tropics are spread woody plant diverse crops, farmhouse woody species planting, and multistory dwelling and also described the traditional AFS as Coffee Shade, home-gardens, woodlots, farm border plantation, and woody plants on grazing lands .those system highest potential to environmental management a humans have always demand from nature for environmental assets. This review shows that the traits of climate change mitigating the capacity of AFS in tropical Africa. The AFS has a vital role to reduce the external change of CO₂ and mitigation through GHG sink from the atmosphere. According to several land-use carbon sequestration reports, the AFS has been known as having the best possible for carbon-capturing from the atmosphere compared to the whole other land uses. This land use has a significant quantity of carbon stored in the total biomass pool compared to mono-crops and or pasture. The aboveground biomass carbon in AFS is estimated to be 2.11 × 1091 Mg C yr^-1 in the region of tropical Afric. The multi-strata AFS has the highest(16-36 Mgt ha-¹ yr^-1)   carbon sequestration were reported, estimated that soil organic carbon (SOC) was highest Fruit-coffee agroforestry systems for 186.41 Mg ha^-1, followed by 178.8 Mg ha^-1 in the coffee-enset, and 177.8 Mg ha^-1 in the Enset system at 0-60 cm depth in Tropical Africa. According to IPCC and several research results,  nowaday AFS as part climate change mitigation strategy. Generally, conserving trees on agriculture land and pasture lands highly recommended as enhancing mitigation capacity of AFS in tropics.
