Shifting cultivation, known across Northeast India as jhum (and as podu in Andhra Pradesh and Odisha, bewar or dahiya in Madhya Pradesh, kumri in the Western Ghats, and penda among the Maria Gond), is among the oldest documented agricultural systems and remains the dominant land-use practice across the hill tracts of Arunachal Pradesh, Nagaland, Mizoram, Manipur, Meghalaya, Tripura and Assam. It is a subsistence-oriented, rain-fed, multi-crop system practised on sloping terrain unsuited to settled plough agriculture. Constitutionally and legally, jhum land in much of the Northeast is governed not by state revenue codes but by customary tenure protected under the Sixth Schedule, which empowers Autonomous District Councils, and by Article 371A (Nagaland) and Article 371G (Mizoram), which bar parliamentary legislation on land and resources without state assembly consent. The Forest Rights Act, 2006 explicitly recognises shifting cultivation as a community forest resource right under Section 3(1), giving the practice statutory standing it previously lacked under colonial forest law.
The system follows a fixed sequence. Cultivators select a forested or fallow hill plot, fell the standing vegetation during the dry months, allow the slash to dry, and burn it before the monsoon — the ash enriching the otherwise acidic, leached soils with potassium and phosphorus and temporarily raising pH. Seeds of multiple crops are then dibbled into the unploughed, ash-fertilised ground using a digging stick. A single jhum plot characteristically supports a polyculture of upland rice, maize, millets, Job's tears, sesame, cucurbits, yam, taro, chillies, cotton and beans, sown so that harvests are staggered across the season and the soil surface stays covered against erosion. After one to three cropping years, declining yields and weed invasion prompt abandonment of the plot, and the household moves to a fresh site while the exhausted plot is left to regenerate.
The jhum cycle — the interval between successive cultivations of the same plot — is the variable that determines the system's sustainability. Traditional cycles of fifteen to twenty years allowed full secondary-forest regrowth, restoring soil fertility, biomass and the nutrient stock released by the next burn. Variants include rotational community allocation of plots by village councils, the bun terracing of Meghalaya, and the more permanent alder-based jhum of the Angami and Chakhesang in Nagaland, where Alnus nepalensis — a nitrogen-fixing tree — is pollarded and retained on plots to shorten fallow and stabilise fertility, an indigenous agroforestry innovation studied as a model of sustainable adaptation.
Contemporary policy treats jhum as a problem to be replaced. The NITI Aayog constituted a Working Group on Shifting Cultivation in 2018, recommending that jhum lands be reclassified as agricultural rather than forest land and that fallows be recognised in revenue records. The Ministry of Agriculture and the ICAR Research Complex for the NEH Region at Umiam, Meghalaya, promote settled terrace cultivation, horticulture and the Watershed Development Project in Shifting Cultivation Areas (WDPSCA), which has operated since 1994-95. Mizoram launched its New Land Use Policy (NLUP) in 2011 to wean roughly 120,000 families off jhum toward permanent trades; Nagaland and Tripura run parallel rubber and cash-crop substitution drives.
Shifting cultivation must be distinguished from adjacent systems. Unlike settled or terrace cultivation, it abandons plots rather than continuously reusing them and rarely employs the plough, irrigation or chemical fertiliser. It differs from plantation agriculture in being subsistence, polycultural and short-cycle rather than commercial monoculture. It is not identical to generic slash-and-burn in the tropical-forest literature, because jhum is rotational and cyclical rather than a one-off forest conversion, and the fallow is integral to the design rather than degradation. It also contrasts with shifting pastoralism (transhumance), which moves livestock rather than crop plots.
The central controversy concerns shortening cycles. Population pressure, encroachment, and the contraction of available forest have compressed jhum cycles in parts of Mizoram and Tripura to four or five years — too short for fallows to recover — converting a once-balanced system into a driver of soil erosion, weed-dominated Imperata grasslands, reduced biodiversity and carbon emissions. The 2018 ICAR estimates placed area under shifting cultivation across the Northeast at roughly 8,500 to 10,000 square kilometres. Critics counter that long-cycle jhum conserves agrobiodiversity and traditional seed stocks, that substitution schemes often fail by ignoring customary tenure, and that classifying regenerating fallows as "wasteland" or "degraded forest" wrongly penalises a functioning indigenous land-use ethic. The FRA's recognition of jhum rights remains weakly implemented because revenue and forest departments dispute the status of fallow land.
For the working practitioner — a civil servant on a Northeast desk, a development planner, or a UPSC aspirant addressing GS Paper 1 (Indian society, tribal geography) and GS Paper 3 (agriculture, environment) — jhum sits at the intersection of livelihood security, ecological sustainability, customary law and federal sensitivity. Any intervention collides with Sixth Schedule autonomy, Article 371A/371G protections, and the FRA, so top-down replacement without community consent is both legally fraught and frequently counter-productive. The defensible policy direction is fallow lengthening, alder-style agroforestry, secure tenure recognition and value addition to traditional crops rather than wholesale abolition — a nuance that distinguishes an informed answer from a superficial one.
Example
In 2011 the Mizoram government launched its New Land Use Policy to move roughly 120,000 jhum-practising families toward permanent settled livelihoods such as horticulture and animal husbandry.
Frequently asked questions
The jhum cycle is the fallow interval between successive cultivations of the same plot. A fifteen-to-twenty-year cycle allows secondary forest to regenerate and restore soil fertility before the next burn. Population pressure has compressed cycles in parts of Mizoram and Tripura to four or five years, preventing recovery and causing erosion, weed invasion and carbon loss.
