Shifting cultivation, a traditional agricultural practice, has long influenced forest cover dynamics across Southeast Asia. This cyclical process of vegetation clearance, burning, and regrowth carries substantial environmental and socio-economic consequences. In India, shifting cultivation—locally known as jhum—is prevalent in the northeastern states, including Tripura. Over time, socio-economic changes and policy interventions have altered traditional jhum cycles, influencing land use patterns. Continue Reading »
