More Than A Tree: How trees are changing Esther’s future

On most days, you will find Esther Wangari tending to her farm, located deep in the heart of Kirinyaga County, in Kenya’s central highlands. Bordering her maize and beans fields, Esther’s latest passion – tree planting – thrives. For this Kenyan smallholder farmer, her new venture is more than just about planting trees; it is also about her livelihood and securing her family’s future.
Trees Training Climate resilience

Tree planting alongside crops (also known as agroforestry) is transforming the lives of smallholder farmers in sub-Saharan Africa and contributing to maintaining farming as a sustainable, profitable venture. This shift is particularly impactful in rural communities where smallholder farmers are the backbone of local economies.

At One Acre Fund, we provide smallholders with trees alongside training on agroforestry techniques to ensure that both crops and trees receive enough nutrients to support growth. Planting compatible trees alongside crops helps smallholder farmers improve their harvests by promoting a healthy soil ecosystem—many types of tree improve soil fertility, prevent soil erosion and store atmospheric carbon.

“Planting grevillea alongside my other crops is not disruptive; in fact, this species enriches the soil with nutrients. This means that crops such as maize and beans benefit from the nutrients that trees provide.”

Diversified Income = Better Livelihoods

One Acre Fund offers a comprehensive tree package to supplement seasonal harvests, bolstering future financial stability for farmers. Trees can provide significant economic benefits, for example, farmers can sell fruit from trees such as avocados several times a year, diversifying their incomes. Trees also provide a form of long-term savings, as farmers can sell timber once the trees mature, and plant again. Such income is especially useful in seasons where extreme weather, which can cause crops to fail, deprives farmers of income.

Additional income means smallholder farmers can better provide for their families. For Esther, it means investing in her children’s future and their success.

“I have experienced the financial benefits of tree farming. Selling avocados enables me to pay school fees for my children. In the future, I want to open a shoe wholesale store, and I am counting on my trees for funds. This way, I can keep providing for my family.”

1 billion trees by 2030

“If farmers plant 1 billion trees, the impact is great because of the many benefits trees have. Farmers will become economically empowered and planting trees improves soil health and the environment which in turn boosts crop yields and potentially increases farmers' incomes." Esther says.

In 2023, we delivered 42 tree species across nine countries across sub-Saharan Africa under our tree planting program that takes into account local ecosystems, farmer preferences, pest and disease issues, and other environmental factors. With an ambitious target to support the planting of 1 billion trees by 2030 across our country programs; to-date, farmers have planted 250 million over the past five years with us.
