For over five decades, 83 year old Vidyadutt Sharma has nurtured Moti Bagh, his 5 acre farm in a small Himalayan village in northern India.    Around him lie 7000 ghost villages – a chilling testimony to large scale migration by locals in search of employment.     As Vidyadutt Sharma chronicles the changing landscape in verses of resistance, he and Ram Singh, his Nepali farmhand, plough the fields, hoping to return Moti Bagh to its old glory.
