Disparity in Land Ownership

Why in News?

A World Inequality Lab working paper, based on 2011 Socio-Economic Caste Census (SECC) data from 270,000 villages across 10 states, highlights severe land inequality in rural India:

• Top 10% households own 44% of land
• Around 46% households are landless
• States like Bihar and Punjab show the highest inequality

What is Land Ownership Disparity?

Land ownership disparity refers to the unequal distribution of land resources, where a small group controls a large share, while a significant population remains landless.

Causes of Land Ownership Inequality

1. Colonial Legacy and Zamindari System

• British-era land systems concentrated land with zamindars
• Post-independence abolition was uneven and incomplete
• Large landholdings persisted, especially in Bihar and Uttar Pradesh

2. Incomplete Land Reforms

• Weak implementation and elite resistance hindered redistribution
• Example: In Bihar, top households own up to 20.1% of village land
• Reform success varied significantly across states

3. Inheritance and Fragmentation

• Division of land among heirs leads to fragmentation of small plots
• Smallholders (0–2 hectares) form 77.5% of landholders
• Yet, the top 1% control 18% of total land

4. Market and Economic Forces

• Mechanised and commercial agriculture favors large landowners
• In Punjab, nearly 73% households are landless
• High inequality reflected in Gini coefficients (e.g., Kerala ~90)

5. Caste and Social Structures

• Historical dominance of upper castes in land ownership
• Persistent social hierarchy limits access for marginalized groups
• In some villages, a single landlord controls over 50% of land

Key Takeaway

Land ownership inequality in India is driven by colonial legacy, incomplete reforms, socio-economic structures, and market forces, resulting in high land concentration and widespread landlessness.

FAQs

Q1. What does land ownership disparity mean?

It refers to unequal distribution of land where a small group owns most of the land while many remain landless.

Q2. Which states show highest land inequality?

States like Bihar and Punjab exhibit the highest levels of land ownership disparity.

Q3. Why did land reforms fail in India?

Due to poor implementation, political resistance from elites, and administrative challenges.

India’s Fertiliser Dilemma

Why in News?

Rising tensions in the Middle East and disruption of the Strait of Hormuz have sharply impacted global fertiliser supply:

• Urea prices increased by ~50%
• Supply chains disrupted due to regional instability
• Raises concerns for India, a major food producer feeding ~20% of the global population

What is India’s Fertiliser Challenge?

India faces a policy dilemma between:

• Ensuring affordable fertilisers for farmers (food security)
• Maintaining fiscal discipline (economic sustainability)

Key Concerns in Fertiliser Imports and Subsidies

1. Fiscal Burden and Rising Public Debt

• India’s public debt is around 81% of GDP
• Interest payments: ~5.1–5.3% of GDP annually
• High fertiliser subsidies:

• India is the largest rice producer (~152 million tonnes projected 2025–26)
• A production fall (~16.7 million tonnes) could:
• Disrupt global supply chains
• Trigger export restrictions (as seen in 2007)
• Lead to sharp rise in global food prices

5. Risks of Sudden Organic Transition

• Push towards organic fertilisers (e.g., manure)
• Challenges:
• Lower immediate productivity
• Supply limitations
• Example: Sri Lanka (2021 fertiliser ban)
• 44% drop in harvest
• Severe economic and political crisis

Key Takeaway

India’s fertiliser dilemma lies in balancing subsidy-driven food security with fiscal sustainability, amid rising import dependency and global supply disruptions.

FAQs

Q1. Why is India dependent on fertiliser imports?

Due to limited domestic production and high agricultural demand, India relies heavily on global fertiliser markets.
