About
Farm Africa
Farm Africa is an international NGO that has worked alongside smallholder farmers, pastoralists and forest communities across eastern Africa since 1985, helping them raise yields, grow incomes and build resilience to a changing climate. Through its Strengthening Regenerative Agriculture in Kenya (STRAK) programme - funded by the IKEA Foundation through AGRA - Farm Africa has supported more than 50,000 farmers in Embu and Tharaka Nithi counties to adopt regenerative practices that restore soil health while improving farm productivity. To scale that work, and to prove its value to the funders and partners behind it, Farm Africa needed verifiable evidence of what those practices were doing to the land.

challenges
Proving the programme worked, at scale
Farm Africa had no scalable way to measure soil carbon across 50,000 farms. Without that evidence, there is no way to prove impact to the funders and carbon markets the programme depended on.

challenge 1
Proving impact at scale
Regenerative practices were working, but no credible way existed to measure soil carbon across thousands of farms.

Our response
Measured soil outcomes, at scale
We measured soil carbon across the entire STRAK landscape from 2017, fusing earth observation with ground-truth data. It needed no field campaigns and no farm visits, and it tracked how the soil actually changed over time.

Carbon quantified, not estimated
SOC rose from the low 40s to around 50 tonnes per hectare, 2017 to 2024. Across the landscape, 1.11 million tonnes of soil organic carbon - roughly 4.07 million tonnes of CO2e.

These results clearly demonstrate that regenerative agriculture is not just an environmental intervention, it is an economic one.

On-farm outcome
Stanley Riungu harvested one bag of maize per acre. After regenerative practices, he harvested three from the same land.
