In the fertile Satara district in western India, farmers are putting their cattle on an unorthodox diet: Some feed iceberg lettuce to buffalo. Others feed strawberries to cows.

It's not a treat. They can either feed their crops to animals or let them spoil. And other farmers are doing just that — dumping truck loads of fresh grapes to rot on compost heaps.

The farmers cannot get their produce to consumers because of lockdowns that aim to stop the spread of the coronavirus. In India, as in many parts of the world, restrictions on population movement are wreaking havoc on farming and food supply chains and raising concern of more widespread shortages and price spikes to come.
