Agroforestry is land-use systems and technologies where woody perennials are deliberately used on equivalent land management units as crops and/or animals. Its systems combine tree growing with the assembly of different crops or animals. Hence, developing positive ecological and economic interactions between components, agroforestry systems aim to produce a variety of environmental, economic and social advantages to farming communities. It plays a major role in soil conservation and global climate change mitigation particularly due to its tree component. Trees control soil degradation through their roots and accumulate greenhouse emission (GHG) in their biomass. What is more, it conjointly helps in global climate change adaptation. It’s a long-time undeniable fact that despite our gift effort at global climate change mitigation (GHG reduction), there is an additional pressing ought to address the impact of global climate change (adaptation). Peoples ought to be acutely aware regarding the scope and advantages of agroforestry and that they ought to participate in the implementation and development of agroforestry within the country. Thus, this paper reviews different analysis findings on the opportunities and challenges for scaling up agroforestry practices. Therefore, the agroforestry system is economically and ecologically sound practices with an improvement of overall farm productivity, soil enrichment through litterfall, maintaining environmental services like international global climate change mitigation (carbon sequestration), phytoremediation, watershed protection and biodiversity conservation.


Subject Outlook for deforestation in sub-Saharan Africa. Significance The UN Food and Agriculture Organisation's World Forestry Congress last week said that the world has lost 129 million hectares (ha) of forested area since 1990, mainly in tropical Africa and South America. Three of the ten states with the fastest declines since 2010 are in sub-Saharan Africa (SSA), due to demand for wood-fuel and timber for export. Much of the timber is traded illicitly, depriving states of revenue. Impacts Large-scale deforestation could undermine long-term climate change mitigation; forests are critical for absorbing carbon dioxide. The depletion of reserves of rare trees such as Madagascan rosewood will raise its value over time, boosting demand. Gabon's afforestation push -- it has gained 200,000 ha since 2010 due to state programmes -- will support eco-tourism.

While closed canopy forests have been an important focal point for land cover change monitoring and climate change mitigation, less consideration has been given to methods for large scale measurements of trees outside of forests. Trees outside of forests are an important but often overlooked natural resource throughout sub-Saharan Africa, providing benefits for livelihoods as well as climate change mitigation and adaptation. In this study, the development of an individual tree cover map using very high-resolution remote sensing and a comparison with a new automated machine learning mapping product revealed an important contribution of trees outside of forests to landscape tree cover and carbon stocks in a region where trees outside of forests are important components of livelihood systems. Here, we test and demonstrate the use of allometric scaling from remote sensing crown area to provide estimates of landscape-scale carbon stocks. Prominent biomass and carbon maps from global-scale remote sensing greatly underestimate the “invisible” carbon in these sparse tree-based systems. The measurement of tree cover and carbon in these landscapes has important application in climate change mitigation and adaptation policies.
