Ashoka Shivareddy comes from a family of farmers, but it was hard to make a living in their drought-prone district of Kolar in southern India.
"The area receives rainfall of only 60 to 70 centimetres, and farmers dig borewells of up to 1,300 feet - most of their money goes into chasing water," he says.
Amid mounting losses the family gave up farming and in 2005 moved to the city - to Bengaluru - and started a vegetable shop.
Shivareddy became an AI software engineer, but he never lost the farming bug.
