'Regenerative agriculture' is all the rage—but it's not going to fix our food system, says researcher
Decades of industrial agriculture have caused environmental and social damage across the globe. Soils have deteriorated and plant and animal species are disappearing. Landscapes are degraded and small-scale farmers are struggling. It's little wonder we're looking for more sustainable and just ways of growing food and fiber.
The term "regenerative agriculture" was coined in the 1970s. It's generally understood to mean farming that improves, rather than degrades, landscape and ecological processes such as water, nutrient and carbon cycles.
Today, regenerative agriculture is promoted strongly by multinational food companies, advocacy groups and some parts of the farming community. And the Netflix documentary Kiss the Ground features celebrity activists promoting the regenerative agriculture movement.
But as our new research shows, regenerative agriculture may not be the transformation our global food system needs.
Farming must change
About 20-40% of the global land area is degraded. Agriculture caused 80% of global deforestation in recent decades and comprises 70% of freshwater use. It is the biggest driver of biodiversity loss on land and contributes significantly to greenhouse gas emissions.
Global corporations such as Nestlé, PepsiCo, Cargill and Bayer dominate the food system. Some 70% of the global agrochemicals market is owned by just four companies and 90% of global grain trade is dominated by four businesses. This gives these corporations immense power.
Many small-scale farmers struggle to compete in global markets—especially those in poorer, less developed countries in Asia, Africa and Latin America. In an effort to keep up, these farmers also often go into debt to buy chemicals and expensive machinery to boost production.
What's regenerative agriculture?
Regenerative agriculture is proposed as a more sustainable alternative to industrial agriculture. It can include practices such as:
- integrating livestock into cropping systems to replenish soil and reduce the cost of animal feed and fertilizer
- leaving soil undisturbed and covered with plants to retain carbon, moisture and nutrients and reduce erosion
- regularly moving livestock between paddocks to give pasture a chance to recover
- using less synthetic chemicals in farming.
But can regenerative agriculture transform the global food system? Our research examined this question.
Our research findings
We explored the origins and current status of regenerative agriculture. We then compared this to other sustainable farming approaches: organic agriculture, conservation agriculture, sustainable intensification, and agroecology.
We found regenerative agriculture shares many similarities with the first three movements listed above. Most importantly, it originated in the rich, industrially developed Global North, primarily North America, Australia, New Zealand and the United Kingdom.
This means the movement often fails to credit Indigenous practices it draws from. It also tends to overlook the needs of farmers in the Global South and broader power inequality in the food system.
Like some other movements, regenerative agriculture is increasingly being embraced by corporations. Nestlé, for instance, aims to source 50% of its key ingredients through regenerative agriculture by 2030.
There are concerns companies may be using regenerative agriculture to "greenwash" their image. For example, experts warn corporations could be using the term to repackage existing commitments, rather than substantially improving their systems.
Agroecology: A different path
We also found that regenerative agriculture is threatening to marginalize another promising sustainable farming movement: agroecology.
Agroecology combines agronomy (agricultural science) and ecology, and also seeks to address injustice and inequity in food systems.
Some researchers question if agroecology alone can produce enough food for a growing global population. But 80% of the world's food, in value terms, is produced by small family farms. And globally, we already grow enough food to feed ten billion people. The problem is how that food is distributed and wasted, and how much is made into ultra-processed foods and other products such as bio-fuels.
Agroecology brings many benefits to farmers and communities. An agroecology project in Chololo village in Tanzania, for example, saw the number of households eating three meals per day rise from 29% to 62%. Average household income increased by 18%. The average period of food shortage shortened by 62% and agricultural yields increased by up to 70%.
But the origins of the agroecology movement in the Global South, and its resistance to corporatisation, mean it is often marginalized. At events such as the UN Food Systems Summit, for example, corporate stakeholders guide policy decisions while vulnerable farmers can feel sidelined.
Transforming our food systems
Despite regenerative agriculture's popularity and its focus on sustainable food production, it fails to tackle systemic social and political issues. As a result, the movement may perpetuate business-as-usual in the food system, rather than transform it.
But our food system includes many landscapes and cultures. That means regenerative agriculture could still support more sustainable farming in some settings—though it's not a catch-all solution.
And voices in regenerative agriculture have called for a shift in the movement's agenda, putting more emphasis on equity, justice and diversity. So there is hope yet that the movement may help turn the tide against industrial agriculture.
