Africa: Soils Should Have Rights Too

press release

A pioneer in soil research and Conservation Agriculture, Dr. Rattan Lal paved the way in one of FAO's key areas of work

Growing up on a small farm in India, Dr. Rattan Lal experienced much of the hardship faced by today's smallholder farmers. His family didn't have running water or electricity, but he explains, "We never missed it because that was the way everybody lived."

As a farmer, his father struggled with irrigation challenges and the related issue of saline soil, both of which Lal later realised could be remedied by improving drainage of the land. But it wasn't until after years of studying that he began to understand and teach the world about the fundamental role of soil.

In fact, a Nobel Peace Prize* and a World Food Prize later, Lal has changed the way we view sustainable soil management and has trodden new ground in what we now call Conservation Agriculture (CA), an approach that can play a huge role in restoring the world's neglected soils, capturing carbon and combating food insecurity.

At its core, CA minimises soil disturbance (which means reducing tilling), provides permanent soil cover and diversifies crop production, all of which can contribute to enhancing biodiversity, reducing water use and improving soil health.

Conservation Agriculture plays an important part in how FAO supports small-scale farmers in Africa, Asia, Latin America and the Caribbean. The benefits of this approach are numerous, from increased yields and reduced costs for farmers to healthier soils and greater carbon sequestration. Lal came to understand all of this and has since endeavoured to spread the word.

A pioneer

In the 1970s, when Lal was working for the International Institute of Tropical Agriculture (IITA) in Nigeria, he discovered that by eradicating ploughing practices and simply covering the soil with crop residues he was able to produce five tonnes of maize per hectare every season; local farmers could only manage one tonne. Yet, for some reason, they still wouldn't adopt CA practices.

He put this down to a distrust in no-till agriculture. Over forty years later, FAO and other organisations like the African Conservation Tillage Network (ACT) are scaling up CA practices in Africa with much more success.

For instance, through the project Strengthening coordination, scaling up and governance of Conservation Agriculture in Southern Africa, FAO is increasing the adoption of CA among farmers.

Given that this region is warming at twice the global rate, there is a pressing need to strengthen food systems and increase the resilience of farmers, many of whom practice either small-scale or subsistence farming. To do so, the project is boosting collaboration between governments, NGOs and development agencies, meaning that FAO and its partners are better able to document and share CA knowledge and best practices with farmers.

A recent example of such a collaboration comes from Zimbabwe, where FAO and the NGO, Foundations for Farming, have been supporting the government in its ambitious target of training 1.8 million farmers in CA.

"I see no reason why Africa cannot become the breadbasket of the world," Lal says.

Restoring neglected soils

Over many years, soils have been neglected: monocropping and the improper use of chemicals have depleted the essential nutrients and microbes found in healthy soils. To reverse this trend, Lal insists that farmers should first manage soil fertility through organic matter.

"Farmers don't return what they take away and consequently soils are degraded. People are a mirror image of the soil they live upon: their health is also equally affected."

When it comes to land use, he insists that we have more than we need - we just don't use it properly.

"This idea of producing more and more and wasting more and more is a crime against nature. The ideal philosophy is producing more from less: less land, less water, less fertilizer, less pesticide, less greenhouse gas (GHG) emissions, less wastage."

Although he admits that soil and CA alone will not offset GHG emissions, "Restoring carbon in soil and trees is the lowest hanging fruit and has many core benefits: food and nutrition security, improved water quality and greater biodiversity."

"If we employ science-based practices, no-till, cover cropping and CA," he says, "agriculture has to be a solution to climate change."

Wide-eyed optimism

Ultimately, Lal believes the role of soil is far too fundamental to ignore.

"Soil is a living thing: 25 percent of all biodiversity is in soil," he says. "And like any living thing, soil should also have right to be protected, restored and managed properly."

Lal is incredibly optimistic: he's glad to see a growing appreciation of soil and praises international efforts to combat climate change.

"FAO and other organisations are now recognising the importance of soil: my recent [World Food Prize] award is testimony enough to this."

As the climate changes rapidly in many parts of the world, FAO is encouraging the adoption of more resilient and efficient production systems such as CA. If the world's small-scale farmers are to achieve food security, soils must play a key role. This is why FAO promotes sustainable soil management through initiatives such as the Global Soil Partnership and celebrates World Soil Day - held annually on 5 December - to raise awareness on the importance of soil resources.
