Land Use Categories in India

The Agricultural Statistics (1949) classified land in India into 9 categories. These categories are recorded in Land Revenue Records and reflect how land is used in agriculture, forestry, settlements, and other purposes.

Overview

9-fold classification of land in India was first introduced in 1949.

Maintained in Land Revenue Records by the Ministry of Agriculture.

Reflects share of forests, agriculture, fallows, wasteland, and settlements.

Net sown area is the largest category, covering about 42.4% of land.

Forest cover (24.62%) is crucial for ecology, biodiversity, and livelihoods.

Land Use Categories in India
Category	Share (%)	Details
Forests	24.62%	Forest cover indicates presence of trees; Forest area means legal status in government records.
Net Sown Area	42.4%	Land used for sowing and harvesting crops; 3–4 crops grown annually.
Misc. Tree Crops	1%	Privately owned cultivable land with orchards, bamboo, bushes, etc.
Non-Agricultural Uses	8.7%	Settlements, industries, roads, canals, ponds, shops, railways.
Permanent Pastures & Grazing Land	3.92%	Owned by Panchayat/Government; used for grazing; part of CPR.
Barren & Uncultivable Land	5.5%	Unfit for cultivation; includes deserts, ravines, hilly terrain.
Current Fallows	4.9%	Left uncultivated for less than 1 year; soil fertility restored naturally.
Other Fallow Land	3.6%	Left uncultivated for more than 1 year but less than 5 years.
Culturable Waste Land	4.41%	Not cultivated for 5+ years; can be reclaimed through improvements.

Important Concepts – CPR vs Public Resources
Parameter	Common Property Resources (CPR)	Public/State Resource
Ownership	Owned by state; communities get ‘use rights’, may/may not have collective ownership.	Exclusively owned by state; people not excluded from enjoying.
Examples	Panchayat village lands, community-owned canal irrigation.	Marine fisheries in EEZ, national highways.

FRP: Fair and Remunerative Price for sugarcane, fixed under the Sugarcane (Control) Order, 1966.

PM-AASHA (2018): Price Support Scheme (pulses, oilseeds, copra – procured by NAFED), Price Deficiency Payment Scheme and a private procurement pilot.

Price Stabilisation Fund (2015): builds buffers of pulses and onions to control price spikes.

Marketing

APMC Acts: state laws regulating mandis; the Model APLM Act, 2017 and Model Contract Farming Act, 2018 encourage reforms.

e-NAM (2016): online trading platform linking APMC mandis across India, run by SFAC.

Institutions: NAFED (cooperative procurement agency, 1958); PACS (primary agricultural credit societies – being computerised); APEDA (export promotion of agricultural products); WDRA (negotiable warehouse receipts); agricultural commodity futures trade on NCDEX under SEBI.

Risk, Credit and Income Support

PMFBY (2016): farmer premium 2% (kharif), 1.5% (rabi), 5% (commercial/horticultural crops); voluntary for all farmers since 2020.

Kisan Credit Card (1998): short-term crop loans, extended to animal husbandry and fisheries; interest subvention brings the effective rate to 4% on prompt repayment.

PM-KISAN: ₹6,000 a year in three instalments; PM-KMY (2019): voluntary contributory pension of ₹3,000 a month at 60 for small and marginal farmers aged 18–40.

Agriculture Infrastructure Fund (2020): ₹1 lakh crore financing for post-harvest infrastructure with 3% interest subvention.

Inputs

Fertilisers: urea at a fixed MRP (100% neem-coated since 2015); Nutrient Based Subsidy for P and K fertilisers (2010); 'Bharat' single brand (2022); nano urea.

PM-PRANAM (2023): rewards states that cut chemical fertiliser use with 50% of the subsidy saved.

Soil Health Card (2015): soil testing with crop-wise fertiliser advice.

Operation Greens (2018): began with tomato, onion and potato (TOP); later extended to more perishables.

Food Security

FCI and buffer stocks: the Food Corporation of India (1965) procures, stores and moves grain; OMSS sells surplus wheat and rice in the open market to cool prices.

NFSA, 2013: covers up to 75% of the rural and 50% of the urban population – 5 kg grain per person per month (35 kg per household under Antyodaya), free since 2023 under PMGKAY; the eldest woman is head of household for the ration card.

PDS reforms: One Nation One Ration Card (portability), Aadhaar seeding, ePoS machines.

WTO: the Bali 'Peace Clause' (2013) protects India's public stockholding from challenge; NAMA talks concern industrial goods, not agriculture.

Key Farm Schemes
Scheme	Year	Purpose
Kisan Credit Card	1998	Cheap short-term farm credit
Soil Health Card	2015	Soil testing and nutrient advice
e-NAM	2016	National online market for farm produce
PMFBY	2016	Low-premium crop insurance
PM-AASHA	2018	Price support for pulses and oilseeds
Agriculture Infrastructure Fund	2020	Credit for post-harvest infrastructure
PM-PRANAM	2023	Reduce chemical fertiliser use

Prelims tips

MSP covers 22 mandated crops on CACP advice; sugarcane gets FRP instead.
PMFBY premium: 2% kharif, 1.5% rabi, 5% commercial/horticulture.
e-NAM (2016) is implemented by SFAC; NAFED procures pulses/oilseeds under PM-AASHA.
NFSA 2013: 75% rural, 50% urban; 5 kg per person per month; AAY 35 kg per household.
OMSS releases FCI stock in the open market; the Peace Clause (Bali 2013) protects public stockholding.

Mains points

MSP-led procurement is concentrated in a few crops and states (wheat and rice in Punjab, Haryana, MP), skewing cropping patterns and groundwater use.
Fragmented APMC markets, high commissions and poor storage keep farmers' share of the consumer price low; e-NAM and FPOs aim to fix this.
Fertiliser subsidy distorts nutrient use (excess urea, poor N:P:K ratio); balanced fertilisation and soil testing improve soil health.
Food security has shifted from calories to nutrition – fortified rice, millets in PDS and portability under One Nation One Ration Card.

Did you know?

The CACP was set up in 1965 as the Agricultural Prices Commission.
India runs one of the world's largest food distribution programmes, reaching about 80 crore people.
Neem coating slows the release of nitrogen from urea and curbs its diversion for industrial use.

Crop Diversification in India

Crop diversification means shifting from a few dominant crops—especially the paddy–wheat cycle of the north-west—to a wider mix of pulses, oilseeds, millets, horticulture and allied activities. It can restore groundwater and soil health, improve nutrition and raise farm incomes, but farmers shift only when markets, procurement and risk support make alternatives viable.

1. Why Diversify

Water: Paddy in Punjab and Haryana depends on groundwater; water tables are falling rapidly in many blocks.

Soil: Monocropping and heavy fertiliser use degrade soil health.

Climate resilience: Millets and pulses tolerate heat and drought better.

Nutrition: More pulses, oilseeds, fruits and vegetables address protein and micronutrient gaps.

Income and imports: High-value crops raise income; more pulses and oilseeds cut India's large edible-oil imports.

Environment: Less paddy means less stubble burning and methane emissions.

2. Types of Diversification

Horizontal: Adding more crops or shifting area to different crops (intercropping, crop rotation).

Vertical: Adding value through processing, dairy, poultry, fisheries, agro-forestry.

3. Policy Initiatives

Crop Diversification Programme under RKVY in Green Revolution states (Punjab, Haryana, western Uttar Pradesh).

Haryana's Mera Pani Meri Virasat (2020): Incentive per acre for farmers who shift from paddy.

International Year of Millets (2023), proposed by India and declared by the UN; millets branded as 'Shree Anna'.

National Mission on Edible Oils – Oil Palm (2021) and pulse self-reliance efforts.

MIDH (Mission for Integrated Development of Horticulture); horticulture output now exceeds foodgrain output in volume.

4. Barriers

Assured MSP procurement for rice and wheat but weak procurement for alternatives; lack of storage, processing and markets; price risk; free power and water favouring paddy; limited seed and technology for new crops; small holdings.

5. Way Forward

Procurement and price support for pulses, oilseeds and millets; payment for ecosystem services or per-acre incentives; FPO-led market linkages; crop planning based on agro-climatic zones and water budgets; inclusion of millets in PDS and mid-day meals.

Paddy–wheat vs diversified cropping
Aspect	Paddy–wheat system	Diversified system
Water use	Very high	Lower (millets, pulses)
Market support	Assured MSP procurement	Uncertain markets
Soil health	Declining	Improves with rotation and legumes
Risk	Low price risk, high ecological risk	Higher price risk, lower ecological risk

Prelims tips

2023 was the International Year of Millets, proposed by India.
Millets are branded as 'Shree Anna' in India.
Mera Pani Meri Virasat is a Haryana scheme for shifting away from paddy.
National Mission on Edible Oils – Oil Palm was launched in 2021.
Vertical diversification means adding value or allied activities, not just changing crops.

Mains points

The paddy–wheat cycle is locked in by MSP procurement, free power and assured markets; diversification requires changing these incentives.
Diversification links agriculture to water security, nutrition and climate goals.
Farmers respond to prices and risk, not advice; assured procurement or price deficiency payments for alternatives are needed.
Regional planning matters: what suits rain-fed central India differs from irrigated Punjab.
Vertical diversification into dairy, fisheries and processing raises income without increasing water use.
