From Dust Bowl to Bread Basket: Digging the Dirt on Soil Erosion

Author: Caspar van Vark

Can we achieve a 70% increase in food production by 2050? It’s often quoted as an objective, but some areas of Africa have seen agricultural productivity decline by half due to erosion and desertification. If productivity is ever to go up, we may need to start by looking down: at the soil.

This is the International Year of Soils, so policy attention is likely to shift to this resource. It’s not a moment too soon, according to Bashir Jama, director of African agriculture body Agra’s Soil Health Program (SHP).

“Around 65-70% of arable land in Africa is degraded in one form or another,” he says. “Farmers are on average getting a tonne of maize from a hectare of land, where a similar size plot in Asia gets three tonnes per hectare. Soils have been cultivated for many years with little or no inputs, and this is compounded by problems of erosion. So the challenge is how to replenish soil and mitigate degradation.”

A recent report on conserving, restoring and enhancing Africa’s soils recommends a holistic approach to soil management called Integrated Soil Fertility Management (ISFM). This includes adding organic matter such as crop residues and manure into the soil, applying small (and therefore affordable) amounts of mineral fertilisers and planting legume crops such as cowpea that naturally deposit nitrogen into the soil.

SHP has taught farmers about these methods via 130,000 demonstrations in 13 countries over the past five years. “The demos are on farmers’ land, school fields, churchyards or roadsides,” says Jama. “One plot might have little or no inputs, with a second plot showing the microdosing of fertiliser – very small amounts placed in the planting hole, along with manure – and another plot might have legumes where, in the next season, they can put sorghum where previously they had legumes.”

Why The Keyword In Farming Startups Is ‘Regenerative’

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.
