Professor Tomo Riba was born in a shifting cultivator's family on 16th February 1961 in Diisi village, Basar of West Siang District, India. His father was a local shaman who used to perform rituals of the village. His mother was well versed in traditional knowledge system being a daughter of a shaman and a wife of a shaman. Her son-in-law is also a great shaman. After the death of his father, author had to help his mother in shifting cultivation at very young age under compulsion. Most of the ideas in this book are reconstruction of own experiences and memories of the teachings of his mother. Most of the information is first hand information. Thus, author knows the pains and pleasure of shifting cultivators.
It has been a long desire of the author to write a book on shifting cultivation before much of the Traditional Ecological Knowledge of farmers disappeared along with the natural death of shifting cultivation.
