Explanation:

Jhum (Shifting) cultivation is a primitive  practice  of  cultivation in States of North Eastern Hill Region of India and people involved in such cultivation are called Jhumia. The  practice involves clearing vegetative/forest cover on land/slopes of hills, drying and burning it before onset of monsoon and cropping on it thereafter. After harvest, this land is left fallow and vegetative regeneration is allowed on it till the plot becomes reusable for same purpose in a cycle. Meanwhile, the process is repeated in a new plot designated for Jhum cultivation during  next year.
