In Sub-Saharan Africa, where farming engages 52% of the workforce, agroforestry is gaining traction as a transformative agricultural practice. This part of agriculture entails interspersing trees among other crops or grazing lands and holds great promise for diversifying production while enhancing agricultural output and substantially boosting practitioners’ income. Addressing food insecurity and poverty, tree planting in Africa offers substantial benefits to smallholder farmers. With support from local government subsidies and foreign aid, more agricultural workers are adopting agroforestry, driving positive change for millions.

Enhancing Productivity Through Agroforestry

Tree planting in Africa offers farmers a versatile agricultural method, allowing them to choose from a variety of native tree species. These species fall into three primary categories: fertilizer, fruit or nut-bearing and fuelwood. Fertilizer trees increase soil fertility and nutrient density, often more effectively than synthetic alternatives. By integrating these species through intercropping techniques, farmers significantly improve agricultural productivity and enhance crop resilience to flooding and other challenging conditions.

Diversifying Income through Tree Planting

Fruit- and nut-bearing trees provide rural Africans with a significant opportunity to earn extra income by selling their byproducts. For livestock farmers, these trees are especially valuable. The foliage serves as important feed, improving the productivity of grazing animals. These trees offer crucial shade and shelter for livestock during hot seasons or droughts.

Fuelwood trees, also known as timber trees, are known for their fast growth rates. Although not directly integrated into agricultural practices, these trees provide significant benefits. Farmers can sell their wood for fuel or construction. They can also use the timber to make furniture or other goods for sale, thereby increasing and diversifying their income opportunities.

Regardless of the tree variety each farmer prioritizes, tree planting in Africa provides significant economic benefits. African governments and international aid initiatives recognize agroforestry’s potential, offering subsidies, grants and educational programs to encourage farmer participation. These programs are often organized by region, with a focus on initiatives in Western and Southeastern Africa.

Agroforestry in West Africa

Agroforestry stands out as a key agricultural method in West Africa, especially in countries like Mali, Burkina Faso and Ghana. Burkina Faso and Mali lead the way, with about 50% of households engaging in agroforestry. This contributes to tree-based products making up roughly 25% of their income. These countries actively use agricultural subsidies and capacity-building initiatives to strengthen their farming communities. This support spurs economic growth and helps reduce poverty among rural populations.

Foreign aid plays a pivotal role in supporting farmers across these countries with grants and educational programs. A key example is the Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) Program, backed by USAID under the U.S. government’s Feed the Future initiative. This program assists farmers in adopting innovative agricultural practices, such as tree planting in Africa. Focused on adding value, improving market access, and forging partnerships, Africa RISING has made significant progress in West Africa and beyond, targeting 1.1 million households between 2016 and 2021.

USAID further collaborates with Mali’s government through its Country Development Cooperation Strategy, which aims to provide agroforestry assistance to more than 64,000 farmers by subsidizing improved technologies and offering education on enhanced management practices. With the potential to benefit nearly 200,000 individuals, this initiative alone is anticipated to decrease the prevalence of hunger in Mali by a substantial 14%.

Initiatives in Southeast Africa

In Tanzania, land productivity has dropped by a staggering 70% in the last 15 years. To alleviate this, Africa RISING developed a Land Degradation Index (LDI), which has facilitated effective mapping of areas that stand to gain substantially from the adoption of agroforestry. Comprehensive strategies such as these are essential for engaging with farmers and swiftly addressing issues related to diminished output and are crucial steps toward mitigating the severe impacts of food insecurity and poverty.

Research conducted by CIFOR-ICRAF, an internationally-funded agroforestry organization, has played a pivotal role in supporting Zambia’s endeavors to establish a National Agroforestry Policy. With approximately 80% of Zambia’s population relying directly on natural resources for sustenance, several CIFOR-ICRAF-supported programs are making significant strides in aiding citizens. These initiatives encompass the provision of grants, upscaling activities and facilitating connections between private producers and local entities.

Looking Ahead

Agroforestry in Sub-Saharan Africa represents a beacon of hope for sustainable agriculture and poverty alleviation. With increasing support from local governments and international aid, more farmers are poised to embrace this transformative practice, unlocking new economic possibilities and enhancing food security. The commitment to expanding agroforestry initiatives promises to empower communities, foster environmental resilience and pave the way for a greener, more prosperous future across the continent.
