One of the amazing facts of bamboo is that it is the fastest growing plant in the world. The reason for the speedy growth of bamboo is because all its cells are created at the time when the plant is a tiny bud. After the seed starts to form a plant, the cells starts to elongate rapidly due to which certain bamboo species can grow up to a height of  36 inches in a day. This rapid growth and tolerance for marginal land, make bamboo a good candidate for afforestation, carbon sequestration and climate change mitigation. It is believed that a total of 45 bamboo species grow in Assam. Apart from being a source of high economic value, bamboo is considered to be an environment friendly plant as its roots can reduce soil erosion up to 75%, generates more oxygen than equivalent strands of trees, lowers light intensity, protects against ultraviolet rays and is an important atmospheric and soil purifier. Although bamboo is cultivated across the whole state, it is largely produced in North Cachar Hills, Cachar, Karbi Anglong, Nagaon and Lakhimpur.
