Home to leopards, zebras, hippos and elephants, Zambia’s Luangwa Valley is known for its sprawling wildlife sanctuaries. But it’s also where Dale Lewis, founder of Community Markets for Conservation (COMACO), helps transform hungry farmers — who poach on the side to supplement their income — into wildlife protectors. In exchange for honoring a “conservation pledge” to stop killing certain animals for money and use sustainable farming practices, the company’s 61,000 farmers, all of whom work on a small scale, receive up to 20 percent more than the standard market price for their corn, soy and honey, which are then used to create a line of food products that are flying off Zambian supermarket shelves.

As it turns out, COMACO is just one of a growing number of both nonprofit and for-profit enterprises that are taking a new look at the agricultural sector and finding that farmers can renew the land they use — and their livelihood that they draw from it. There’s Honey Care Africa, a for-profit franchise that works with farmers across East Africa to supplement their income through honey production while increasing crop yield with pollination help from their honey bees, as well as the Timbaktu Collective, which helps farmers in a drought-prone region of India sell products grown with traditional water conservation practices. Oh, and don’t forget Peepoo — yep, you read that right — a system that converts sanitation waste from poor urban neighborhoods, refugee camps and disaster relief sites around the globe into nutrient-rich fertilizer for farmers with poor soil quality.

These regenerative agricultural practices, as they’re known, have been developed in response to a growing list of problems plaguing farmers and rural workers around the world: land degradation, drought, crop disease and unpredictable market prices, to name a few. Of course, climate change isn’t helping on any of these fronts. But the trend is also being driven by the growth of B Corps — think of them as certified do-gooder businesses — and other companies that are under pressure to show responsibility for the planet, says Daniela Ibarra-Howell, co-founder and CEO of the Savory Institute, a nonprofit that promotes large-scale restoration of the world’s grasslands through a regenerative practice known as holistic management.

Indeed, some corporations have asked the Savory Institute where to find beef, wool and leather products with the health of land in mind, and where investments are needed along the production supply chain to create a shift in global food systems. Brands that “want to be a good company” are in search of responsible projects — more, even, than consumers demand, says Jill Dumain, director of environmental strategy for the outdoor retailer Patagonia, which purchases regenerative wool.
