The correct option is A Shifting cultivation
Podu cultivation is a form of shifting cultivation. The valleys of the Wayanad hills, particularly in the western hills of taluk, have been cleared and converted into wet rice fields. A good deal of this clearance was done in ancient days by Kurichiyas. These fields are very fertile and the yield per acre is higher than the other parts of the Malabar district. Podu cultivation is very popular among the tribal people of Odisha.
