Rattan Lal: The FAO faces a new agricultural revolution
Rattan Lal
Humanity faces a paradox. We have never had so much scientific and technological knowledge to produce food, yet the need to transform the way we produce it has never been more evident.
The Green Revolution was one of the great successes of the 20th century. Increased agricultural yields made it possible to feed billions of people and avert the famines that many considered inevitable. But that success came at a cost. The intensification of agriculture also contributed to soil degradation, increased use of water and agricultural inputs, and environmental impacts.
The challenge of the 21st century is different. We must produce more with less: more food with less land, higher productivity through more efficient water use, greater prosperity for farmers, more carbon stored in the soil, greater biodiversity, and healthier ecosystems.
This transformation must be at the heart of the next phase of the Food and Agriculture Organization of the United Nations (FAO). Latin America and the Caribbean have much to contribute. The region is one of the pillars of global food security and a vast laboratory for agricultural innovation.
Argentina, Brazil, and other countries have developed production systems that incorporate science, technology, precision agriculture, no-till farming, genetic improvement, and new natural-resource management practices.
The biome known as the ‘Brazilian Cerrado’ is an extraordinary example. Scientific research and decades of innovation made it possible to transform a region once considered to have limited agricultural potential into one of the world’s major food-producing centres.
The lesson is not to mechanically transplant that model to other regions. The lesson is that science can transform natural constraints into opportunities for development.
Africa today needs its own agricultural revolution. There is no universal recipe. But there is a universal principle: science must guide decisions.
I have dedicated much of my scientific life to demonstrating that soil health is inextricably linked to the health of plants, animals, people, ecosystems, and, ultimately, the planet. There can be no lasting food security with degraded soils.
That is why I consider the experience of ‘Living Soils of the Americas’ to be particularly important, an initiative we developed together with the Inter-American Institute for Cooperation on Agriculture (IICA) during the tenure of Argentine Manuel Otero.
The initiative brought together scientists, governments, farmers, businesses, and civil-society organisations around a fundamental idea: increasing production and protecting the environment are not conflicting goals. Healthy soils can store carbon, conserve water, strengthen biodiversity, improve resilience, and, at the same time, sustain agricultural productivity.
The experience gained in the Americas then began to extend to Africa. Innovations developed over decades in places like Brazil’s Cerrado can offer valuable insights for the African savannas. This exchange epitomises what modern agriculture should be about.
