Drones to help Rajasthan, Gujarat farmers detect crop diseasesHome

Weather forecaster Skymet has already conducted a pilot project in parts of Gujarat to map the groundnut crop along with Agriculture Insurance Company (AIC) of India and will soon be flying across field in the coming summer.

"Remote sensing through unmanned aerial vehicles allows non destructive sampling to observe agronomic indicators every square metre. We did a pilot project last year and will increase its coverage across Rajasthan and Gujarat this year," said Jatin Singh, CEO of Skymet.

The technology has been in use in the United States and other developed countries to map crop position, control farm subsidies, detect pests, monitor nutritional and water stress on crops, and even spray fertilizer and pesticides on crops.

Skymet, along with the AIC and Gujarat government, used satellite remote sensing technologies and drones across 10 villages in Morbi district of Gujarat last year.

"We covered the groundnut crop, clicking images a few centimetres away, which is not possible via satellite," said Singh. Satellite's resolutions are less and if a cloud cover comes, then you can't use the images, he said, adding, "At a time when land holdings are less and there is multi cropping we were able to help Gujarat government in monitoring of the agriculture area and crop yield. The data could help AIC in giving farmers claims."

The automatic and remote controlled UAVs cover 5 sq km in a single flight, with generally two flights (missions) per day. UAVs send images every five seconds and provide geo referenced images.

"It's a beneficial technology for states that have digitised land records or are in the process of digitising. Pictures clicked by the unmanned aerial vehicles can be superimposed on digital maps of states and we can identify farms and crops sown," said PJ Joseph, chairman and managing director of AIC.
