Tree program impact by country
One Acre Fund runs scaled tree programs across nine countries in sub-Saharan Africa. Here we share the updates on each program from 2024.
Overall, in 2024, we estimate that we supported the planting of 90 million trees. In the same year, we reached a milestone by planting our 250 millionth tree since 2019, when we began the tree program. This puts us well on our way to our goal of 1 billion trees planted by 2030.
In Tanzania, Zambia, and Malawi, we are piloting agroforestry carbon projects that connect smallholder farmers to global carbon markets. Supported by nearly 450 dedicated tree nurseries, these pilots have engaged a cumulative 15,000 farmers to plant trees that meet carbon market standards.
Explore the impact of our tree program in each country:
Trees distributed in 2024: 55 million
Tree seedlings distributed since the start of the program: 150 million
Kenya, home to One Acre Fund’s most mature tree program, supported over 750,000 farmers in planting 55 million trees in 2024. Trees were purely distributed via a network of 330 nurseries. We nearly doubled our 2024 target of 28 million trees.
With an eye toward improving impact, the Kenya program has been encouraging farmers to adopt larger numbers of trees, increasing the average planting rate from 31 to 55 trees per farmer. Species diversification continued to play an important role in the Kenya program’s efforts to increase scale and impact. The program increased the number of varieties in its portfolio to 20 in 2024. The program also significantly increased the scale of its fruit and nut tree distribution last year, distributing nearly 120,000 such seedlings, up from 7,000 seedlings in the previous year.
Trees distributed in 2024: 6.5 million
Tree seedlings distributed since program launch: 9.5 million
In 2024, One Acre Fund’s Nigeria program supported over 246,000 farmers in planting over 6.5 million trees, representing a 140% year increase of trees distributed compared to 2023. Seedlings were produced in 346 community-based decentralized nurseries. These decentralized nurseries are the backbone of a resilient and farmer-centered tree-planting movement across Nigeria.
The program serves Niger, Kwara, and Nasarawa states, distributing 8 different tree varieties.
Trees planted in 2024: 25.6 million
Tree seedlings distributed since the start of the program: 117 million tree seedlings
In 2024, One Acre Fund’s Rwanda program supported 1,012,782 farmers in planting over 25 million trees.
Rwanda distributed 20 different tree varieties at scale in 2024, including over 450,000 seedlings of high-value horticultural species (primarily avocado). The vast majority of trees were produced through One Acre Fund’s 2,000+ highly efficient decentralized nurseries. The same year, we launched the Isi Itoshye program, enrolling over 5,000 farmers to plant a customized mix of trees, shrubs, and grasses tailored to their land size.
Excitingly, One Acre Fund and the Rwanda Forestry Authority, which supports landscape restoration, are working together to achieve key environmental outcomes while generating farmer revenues through payments for ecosystem services.
The team has also taken key steps to strengthen its approach to measuring the impact of trees through comprehensive monitoring and tracking.
Trees planted in 2024: 7 million
Tree seedlings produced since the start of the program: 25.9 million tree seedlings
In Burundi, One Acre Fund once again surpassed its agroforestry targets for the year, supporting the planting of 7 million trees by roughly 180,000 farmers. This performance was driven by strong production across 728 decentralized nurseries and continued strong demand for a scalable asset base among the country’s farmers.
One Acre Fund made progress in diversifying the country’s agroforestry offerings in recent years, distributing 4 distinct varieties. This included a targeted focus on high-value fruit trees.
Trees planted in 2024: 4.3 million
Tree seedlings distributed since the start of the program: 8.6 million tree seedlings
In 2024, One Acre Fund's Tanzania program supported 11,000 farmers in planting 4.3 million trees through a network of 209 entrepreneur-run decentralized tree nurseries. Species diversification has played an important role in our Tanzania tree program. In 2024, we distributed 20 different tree varieties in total across timber, fruit, and soil health categories.
Trees distributed in 2024: 16.5 million
Tree seedlings distributed since the start of the program: 38.7 million
In 2024, the Malawi program supported over 560,000 farmers in planting more than 16 million trees through 1,000+ decentralized nurseries. 70% of farmers participating in the program were women.
Malawi’s 2024 performance was primarily driven by strong farmer demand and high planting rates, with seedlings from 5 different tree species that cater to the 4Fs in terms of farmer needs, i.e: Fuelwood, Fertilizer, Food, and Fodder.
The program has also advanced its early-stage agroforestry carbon pilot known as the Munda Otsogola Program. This is a Payment for Ecosystem Services (PES) program implemented in Zomba and Dedza Districts. The program offers smallholder tree farmers the opportunity to generate additional income and adopt sustainable farming practices, thereby benefiting both their livelihoods and the environment.
In 2025, the tree program is running a fruit trial focused on mango and citrus, with the long-term goal of building a portfolio of fruit species that guarantees at least one harvest every month of the year for participating farmers. Priority will be given to pregnant women and young mothers, who will receive a bundle of five or more fruit tree species to support nutrition and food security year-round.
Tree seedlings produced since the start of the program: 6.2 million tree seedlings
Trees distributed in 2024: 3.8 million seedlings
In 2024, our Zambia agroforestry program supported 4,573 farmers in planting more than 1 million seedlings.
Smallholder farmers have access to carbon markets and receive carbon credit payments for the growth of their trees, which provides an additional annual income source. In 2024, farmers received tree survival payments of more than $9,000.
We have diversified our tree offerings to include Faidherbia Albida (Musangu), Gliricidia, Moringa, and fruit trees, providing various solutions ranging from medicinal use to food, timber, and beyond. We work closely with local leaders and the government to roll out the program and incorporate social behavior change to help increase the adoption of agroforestry. Our ultimate goal is to convert more farmland to agroforestry farmland.
Trees planted in 2023: 525,000
Participating farmers: 18,000
Uganda supported 18,000 farmers in planting 525,000 trees in 2023, above the 494,000 trees initially targeted for the year. As in 2022, the program exclusively distributed grevillea seedlings via 25 decentralized nurseries across 4 districts in 1 region. And in an effort to reach more farmers, the program also distributed trees via institutions including churches, schools, and the government’s Ministry of Environment, distributing an estimated 42,000 additional trees.
Beyond grevillea, the Uganda program continued to scale and refine its coffee extension program over the past year. In 2023, One Acre Fund enrolled 10,000 coffee farmers, supporting the sustainable preservation and management of 1.8 million coffee trees. By 2025, One Acre Fund plans to expand to 55 sites, reaching 30,000 farmers managing 7.2 million coffee trees annually.
Trees planted in 2023: 15 million
Participating farmers: 165,000
One Acre Fund’s Ethiopia program, which operates in partnership with the country’s government, supported approximately 165,000 farmers in planting over 15 million trees last year.
