Africa is home to some of the most diverse ecosystems on the planet, yet deforestation has had a significant impact on the continent's environment. The need for afforestation in Africa has become increasingly urgent as the population continues to grow and climate change threatens to exacerbate existing environmental challenges.

Furthermore, afforestation has the potential to provide a significant economic boost to many African countries providing a range of ecosystem services, including carbon sequestration and biodiversity conservation which have economic value. Additionally, Africa can tap into emerging carbon markets and benefit from payments for reducing greenhouse gas emissions.

Afforestation for the Sahel region would have multiple benefits for the local ecosystem. One benefit is the creation of an albedo effect, whereby the trees would reflect sunlight back into the atmosphere, cooling the local climate. This would help to counteract the negative impacts of climate change, such as increased temperatures and decreased rainfall for replenishing aquifers in the Sahel, which are a vital source of water for the local communities. This would not only help to combat desertification but also improve the living conditions of those in the region.

There is an emerging concept for transforming the multi-billion avocado, lumber, and decarbonization markets with the synergistic intercropping of paulownia and avocado trees on marginal lands for creating local food security, jobs, and exports.

Paulownia trees are fast-growing and have deep roots that can help to improve soil structure and increase soil fertility while also producing regenerative and valuable timber every five years. They also can fix nitrogen, which can help to reduce the need for synthetic fertilizers. The large leaves provide shade during hot summer months and, as a deciduous tree, shed their leaves for allowing full sunlight for the avocado trees during the winter.

Avocado trees, on the other hand, have a shallow root system and require a more fertile soil to grow well for producing nutritious fruit. By intercropping avocado trees with paulownia trees, farmers can benefit from the nutrient-rich soil created by the paulownia trees, while also maximizing the use of the land by growing two crops simultaneously.

Intercropping avocado and paulownia trees also creates important environmental benefits. The trees can help to reduce soil erosion, improve water retention, and mitigate climate change by sequestering carbon dioxide. This can contribute to the Net Zero goals of Africa by promoting sustainable land management practices while reducing the impact of climate change.
