The agriculture of the future is emerging as an essential response to the challenge of feeding 9.7 billion people in less than three decades. A warmer, drier world with extreme climates demands radical innovations, according to experts gathered in Madrid. These solutions seek to optimize limited resources such as water and fertilizers.
Plants that ‘breathe’ nitrogen: A revolutionary breakthrough
At the heart of the agriculture of the future lies the ability of plants to fix nitrogen directly from the air, eliminating the dependency on chemical fertilizers. Researchers at the Sainsbury Laboratory in Norwich, UK, have genetically modified rice and wheat to emulate legumes. These plants that ‘breathe’ nitrogen incorporate bacterial genes that convert atmospheric gas into usable proteins, reducing nitrous oxide emissions—a greenhouse gas 300 times more potent than CO2—by 40%, according to studies by the University of Cambridge.
Salt-resistant tomatoes: Adaptation to degraded soils
Salinity resistance in the agriculture of the future
Tomatoes modified to resist salt represent another pillar of the agriculture of the future. CSIC scientists in Spain have developed varieties that thrive in saline soils, common in arid regions affected by intensive irrigation. These plants accumulate salts in cell vacuoles, maintaining their productivity. Tests in Almeria show yields 25% higher under adverse conditions, crucial for areas like the Mediterranean and the Middle East, where salinity affects 20% of global arable land, according to the FAO.
- UN projections indicate that by 2050, 50% of the population will live in water-scarce areas.
- The agriculture of the future could reduce water use by 30% through drought-tolerant crops.
- Experts like geneticist Jonathan Jones point out: “These innovations save lives on an overpopulated planet.”
Historical context and pending challenges
Since the Green Revolution of the 1960s, which doubled food production, the agriculture of the future is evolving toward biotechnology. However, EU regulations limit genetically modified crops, despite their approval in 30 countries. In the Dominican Republic, where climate change threatens crops like plantain and rice, these technologies could boost food sovereignty. Organizations like CIMMYT in Mexico are testing resistant maize, broadening the impact.
The agriculture of the future, with plants that ‘breathe’ nitrogen and salt-resistant tomatoes, not only confronts global warming, but redefines sustainability. Developing countries, including ours, must adopt these tools to guarantee food in an imminent climate crisis scenario.
