31-year-old Ishita Khanna has made it her mission to help residents of Spiti combat climate change. She moved out of Delhi to set up Ecosphere in the Spiti valley. Her aim is to build a green local economy. She got villagers to harvest a local berry, the Seabuckthorn. The fruit is used to make juices and jams. For two weeks a year, when the berry is harvested, the women in 30 Spiti villages earn upto 800 rupees a day. Ishita is also encouraging eco tourism in the area, and is also working to get the locals to give up firewood and use solar technology instead.
