With wild animals keeping off cultivated fields, agricultural productivity increased by 35%, they said.Field director Dudhwa tiger reserve Ramesh Pandey told TOI, “This is a joint initiative of the forest department and WWF-India. The devise detected the presence of animals and kept them away. We are hopeful that the experiment will give as good results as in Uttarakhand.” The presence of an animal can be detected within a 10-metre radius. This alerts farmers and at the same time, repels the animal which retreats..
