Consumer-facing companies like Danone and Mars have pledged to slash their greenhouse-gas emissions, in part by purging deforestation from their supply chains – a process that requires helping hundreds of thousands of farmers change the way they grow their crops. In this series, we’ll take a deep dive into the Kenyan milk market, and see how the revival of agroforestry is restoring soils – and may slow climate change.

13 December 2016 | BUNGOMA, Kenya | Prisca Mayende still remembers the lush, tree-covered countryside of her youth, when the farms in this part of Kenya, about 50 kilometers from the Ugandan border, yielded consistent harvests – year-in and year-out – of sorghum, white corn, and the dark green, kale-like sukuma wiki. Then came the sugar boom, and its bitter consequences.

“They destroyed all the trees to plant sugar,” she recalls. “And that is where the problems started.”

First came the floods, because the trees weren’t there to stop them; then came the dry spells, perhaps because the trees weren’t there to draw in the rain. Finally, the soil stopped producing – as it had in North America during the Dust Bowl, and as it’s doing across Africa today – because the trees weren’t there to replenish the earth.

But then, in 2010, Mayende’s neighbors told her about a man on a motorcycle.

“He was just moving around, looking for those farmers who were in groups,” she recalls. “So, when he [asked] some of the communities, they said, ‘Mama Prisca is one of the farmers who is interested in doing the agroforest.’”

As a leader of the Naikai Community Water Project, she’d been working to coordinate water-use and well-drilling, but the man on the motorcycle asked if members of her group would be interested in planting trees – lots of them – in their cornfields and cabbage patches. It was a tough sale – but not for her.

“People really feared that, maybe, when there are trees on the farm, the production cannot be good,” says Mayende, adding: “But me, I like trees.”

So she took the plunge, and within three years her farm was covered in trees – some fruit-bearing varieties like mango and banana, but mostly varieties like sesbania, albizia, and grevillea – which offered fodder for her cow.

Soon, the birds returned, and today her corn, cabbages, and potatoes are thriving – largely because the trees helped revive the soil – and she’s not alone. All across Africa, Latin America, and Asia, small farmers are replenishing soil by planting trees on formerly sunbaked row-farms; while consumer-facing giants like Danone and Mars are beginning to accelerate the process by investing in programs that support sustainable agriculture.

“We have all forgotten that food starts in soils,” said Danone CEO Emmanuel Faber at last year’s Paris climate talks – sounding more like a soil scientist than a businessman. “We have disconnected the food chain.”

To fix that, Danone spearheaded the creation of two separate Livelihoods Funds, which “create mutual value for smallholder farmers, businesses and society as a whole.” Twelve companies have put money into the programs to date, including Danone and Mars – each of which have also made high-profile deforestation commitments being tracked by the Forest Trends Supply Change project.

In this series, we’ll offer a deep dive into the pioneering work of one agroforestry initiative that is changing the lives of farmers across Kenya, and we’ll see how the arrival of deep-pocketed consumer giants, dairy cooperatives, and flower-growers can accelerate these activities while slowing climate change – especially as new financing mechanisms come into effect under the Paris Climate Agreement.

The Links in the Chain

In 2014, Danone took a 40% stake in Kenyan dairy group Brookside, which had built a nationwide network of collection facilities that gathered milk from more than 130,000 farmers. As Brookside grew, however, they found supply wasn’t keeping up with demand – largely because farmers were leery of moving into the dairy business. Even a single cow, it turns out, is a major investment, and the milk market was a day-to-day affair: on some days, farmers would show up with milk, only to find no buyers.

So Brookside reached out to regional cooperatives like the Kaptama Famers’ Cooperative and guaranteed that they would buy whatever the farmers can produce; but then they noticed something else: in some parts of their territory, farmers brought in three liters per cow on a good day. In other parts, they brought in seven or more, and consistently.

Driving this, they found was agroforestry: those farmers who embraced the practice ended up delivering more milk than those who didn’t. And there was another benefit as well: those who adopted agroforestry spent more time on their farms and less in the forests.

“Most of them used to cut trees,” says Takin Arnold, who runs the cooperative. “But because of the market that Brookside has created, those farmers have left the cutting of trees and embarked on selling to Brookside.”

The Man on the Motorcycle

And that brings us to the man on the motorcycle: Makanda Khisa, who introduced himself to Prisca Mayende as “Johnny”, because that’s what his friends call him.

“I saw him on the motorbike, and he asked me if I was in a group,” Mayende recalls. “I said, ‘Yes, I’m in the Naikai Community Water Project. Then he asked if we are interested in meeting visitors, and I asked him, ‘What kind of visitors?’ And he told me about VI.”

VI Agroforestry is a Swedish NGO that’s been working in Kenya since 1983 – reaching out to farmers and showing them how trees can pull nutrients out of the air and inject them into the soil. Like many NGOs, they’re constantly struggling for finance, and in 2007 they hit upon a novel way of addressing that: namely, instead of just looking for donations, they decided to see if they finance their operations by generating carbon offsets – and not just for the trees they plant.

Healthy topsoil, it turns out, teems with life, and that means carbon. But as we churn through topsoil, we not only extract the nutrients that support agriculture, but we release carbon dioxide into the air — and lots of it: nearly 300 billion tons of carbon dioxide over the last 200 years, according to the Intergovernmental Panel on Climate Change. Rattan Lal, a professor of soil science at the Ohio State University, says we can pull about 10% of our greenhouse gasses out of the air and inject them into soils just by switching to climate-safe agriculture – and agroforestry is one part of that.

So, in 2007, to shore up its chronic funding shortfalls, VI Agroforestry took its 20 years of experience in Kenya and calculated the amount of carbon its activities lock in the soil. Then it drew up a plan to finance its activities by selling carbon offsets, with most of the money going directly to farmers. In 2010, the World Bank decided to test the idea.
