The farmers in a village in the outskirts of Delhi in India are using FM radio as a tool to protect their crops, according to The Hindu Business Line.

A loudspeaker in an empty concrete shed blares FM transmission 24 hours a day to keep away herds of nilgai (the Indian blue antelope) from the fields in Bhaktawarpur.

According to a farmer, the nilgai feels that there is human presence on the fields and stays away.

This is not the only instance where radio has come to the rescue in a difficult situation.

Last month, the Forest Department and the Wildlife conservation society of the northern hill state of Himachal Pradesh issued a unique advisory for those who may encounter a leopard in a forested area.

They encouraged people to keep a transistor handy or turn on the FM on their mobile phone as music apparently keeps the leopard at bay.
