Objective: 

Inspite of the deteriorating status of the environment, study of environment has so far not received adequate attention in our academic programmes. This programme aims at giving students a clear understanding of environmental concerns and to follow sustainable development practices. It will also help to stimulate them to develop their ability to apply their knowledge and adopt a standpoint on environmental issues
