Agriculture 4.0 is helping farmers do more with less

The fourth agricultural revolution promises to grow more food on less land while feeding more people, says Rabiya Abbasi.

With cornstalks swaying on a gentle breeze and cattle in quiet contemplation of the cud, a farm would not seem to be a hotbed of revolution. But make no mistake, agriculture is squarely in the midst of the fourth industrial revolution. Emergent, game-changing technologies are driving economic, environmental, and social change in the global food system. And in the face of rising hunger, populations and a changing climate, everyone from policy-makers to billionaires is paying attention.

The US Association of Equipment Manufacturers published a study in February 2022 investigating how new technologies may help farmers do more with less. On average, new technology triallers achieved a 4 percent increase in crop production, 7 percent reduction in fertiliser use, 9 percent reduction in herbicide use, 6 percent reduction in fossil fuel use, and 4 percent reduction in water use.

Farmers are applying Internet of Things (IoT) technology to track crops remotely, using sensors to detect weed growth, water levels and pest invasion. And we're not only seeing this on traditional farmlands. Farm66, inside a Hong-Kong skyscraper, is using IoT to help manage a 2000-square-metre indoor farm. The IoT-enabled agricultural industry is estimated to reach US$4.5 billion by 2025.
