- "Agrarian class structure has been undergoing changes due to modern forces." Critically examine. (Answer in 350 words)
Introduction
The agrarian class structure has changed at its top and its middle, and hardly at all at its base; modern forces explain the first two and are the reason the third has held.
Body
1. What the structure consisted of: Daniel Thorner's threefold division of malik, kisan and mazdoor captured it: a rentier class holding superior rights under zamindari, ryotwari and mahalwari settlements, a self-cultivating peasantry, and landless labour. Beteille's Sripuram showed the layers coinciding with caste, Brahmin landowners above non-Brahmin tenants and Adi-Dravida labourers.
2. The changes and the forces behind them: Zamindari abolition and tenancy legislation removed the intermediary rentier stratum. The Green Revolution from the late 1960s turned the middle peasantry of Punjab, Haryana and western Uttar Pradesh into a market-oriented, input-buying, labour-hiring class, and the debate between Utsa Patnaik, Ashok Rudra and Kathleen Gough over the mode of production turned on how capitalist it had become. That class became politically dominant, in Charan Singh's constituency, in the Shetkari Sanghatana and in the Bharatiya Kisan Union. Beteille's own restudy found caste, class and power beginning to come apart.
3. What has not changed, or changed for other reasons: Ownership remains concentrated, with more than four-fifths of holdings marginal or small, and Dalits still overwhelmingly supply labour rather than own land. Tenancy reform drove leasing underground into oral, insecure arrangements, so the tenant lost security instead of gaining it; ceiling laws failed everywhere except Kerala and West Bengal's Operation Barga. Where the base has improved it is often through non-farm work, migration and the wage floor set by employment guarantee, not through agriculture. Distress now falls on the cultivating middle the Green Revolution created, expressed in indebtedness and in suicide among landholding farmers.
4. A judgement on the claim: The claim holds for the upper and middle layers and fails at the base. Modern forces redistributed power among those who own land without altering who owns it, and the deepest recent change at the bottom, non-farm income, came from outside agriculture altogether.
Conclusion
Agrarian conflict has moved accordingly, from rent and tenure to wages, prices and procurement.
