India has used traditional methods of agriculture for generations, but with 1.4 billion people now dependent on the crops farmers produce, some are turning to technology to boost productivity and profit. For example on one vineyard, sensor devices are being used to check weather and soil health. Artificial intelligence can then figure out when it’s time to water the crops, add fertilizer and tackle pests. Nitin Patil, who works at the vineyard, says the AI advice has helped “save 50% of the water” the farm had been using previously.
