New Delhi: The Chipko movement was a turning point in the forest conservation efforts in India. During the 1970s, when reckless cutting of trees started affecting people's livelihoods, the villagers from Uttarakhand's Chamoli started hugging trees to prevent them from cutting. This movement, where women participated in large numbers, came to be known as Chipko andolan, with the word "Chipko" signifying a hug or embrace. The champions of the Chipko movement were local women - Gaura Devi, Sudesha Devi and Bachni Devi.
