During the dry season Indian elephants migrate to eastern Nepal, passing through the plains of Darjeeling district in West Bengal in search of food and shelter.
In 2015, an 18-km-long electric fence was put up on the Nepalese side, which prevents Indian elephants from going to Nepal and upsets their seasonal migration.
"This is creating problems on our side. We have taken up the issue with the Indian government and we hope something will be done. We have requested them to take it up with the Nepalese government," Sinha added.
While being unable to follow their migration route, elephants cause much damage to property and people, wandering around human settlements and agricultural lands. As a result, elephants are killed, crops damaged and human lives lost.
