In the colonial period, cultivation expanded rapidly for a variety of reasons of which two are given below:
(i) British directly encouraged the production of commercial crops like jute, sugar, wheat, and cotton. The demand for these crops increased in 19th century Europe where foodgrains were needed to feed the growing urban population and raw materials were required for industrial production.
(ii) In the early 19th century the colonial state thought that forests were unproductive. They were considered to be wilderness that had to be brought under cultivation so that the land could yield agricultural products and revenue and enhance the income of the state.
