Ziro Festival of Music (ZFM), the iconic outdoor music festival is set to be back with a bang after a gap of two years. Scheduled to take place between September 29 and October 2, the festival will be held in the picturesque Ziro Valley located in the Lower Subansiri district of Arunachal Pradesh. Home to the Apatani tribe, the Ziro Valley offers travellers lush paddy fields, pine trees, and a pleasant climate. In addition, over the years, both organizers and residents have worked closely with each other to manage the waste and make the festival more sustainable. Since music festivals like ZFM leave behind a massive carbon footprint, they need to be more sustainable. Here's a look at some ways the ZFM is doing so.
