Land Resources and Agriculture

Analysis of land-use categories, cropping patterns, and the evolution of agricultural strategies from the Green Revolution to sustainable missions.

  1. Land Use Categories

    Revenue records track the 'reporting area', classifying land into categories like forests, non-agricultural uses, and pastures.

    • Reporting vs Geographical Area — Reporting area (Revenue Dept) can vary based on estimates, while geographical area (Survey of India) remains fixed.
    • Forest & Barren Land — Distinguishes between 'area classified as forest' (legal) and actual cover; barren land includes uncultivable hilly or desert terrain.
    • Common Property Resources — Community-owned lands (pastures, water bodies) vital for fodder, fuel, and the livelihoods of landless farmers and women.
  2. Uncultivated Land & Fallows

    Land left out of cultivation for varying durations to regain fertility or due to constraints, requiring different reclamation.

    • Current Fallow — Land left uncultivated for one year or less to allow natural biological processes to restore soil nutrients.
    • Other Fallow & Wasteland — Fallow other than current (1-5 years) and Culturable Wasteland (>5 years) which requires reclamation to be productive.
    • Net Sown Area (NSA) — Represents the actual physical extent of land where crops are sown and harvested.
  3. Cropping Intensity & Seasons

    Measures land-use efficiency and the temporal distribution of agriculture across India's distinct climatic seasons.

    • Intensity Formula — CI = (Gross Cropped Area / Net Sown Area) x 100. Higher CI indicates more efficient land use and labor demand.
    • Agricultural Seasons — Kharif (June-Sep: Rice, Cotton), Rabi (Oct-March: Wheat, Gram), and Zaid (April-June: Vegetables).
    • Southern India Exception — High year-round temperatures allow tropical crops to grow in any season if soil moisture is available.
  4. Foodgrains & Oilseeds

    Cereals and pulses occupy two-thirds of cropped area; oilseeds provide edible oils and industrial raw materials.

    • Cereals: Rice and Wheat — Rice (tropical humid) is the staple; Wheat (temperate Rabi) is concentrated in the Indo-Gangetic Plain and Malwa Plateau.
    • Pulses: Soil Fertility — Legumes like Gram and Tur fix atmospheric nitrogen; India is a leading producer of these essential protein sources.
    • Oilseeds — Occupies 14% of area; includes Groundnut (Kharif), Rapeseed/Mustard (Rabi), and Soyabean (MP/Maharashtra).
  5. Fibre & Plantation Crops

    Industrial and export-oriented crops including textiles and beverages, primarily grown in specific agro-climatic zones.

    • Cotton and Jute — Cotton (Kharif) thrives in semi-arid areas; Jute is a cash crop concentrated in West Bengal for bags and decor.
    • Tea and Coffee — Tea is a Brahmaputra valley (Assam) staple; Coffee (Arabica) is grown in the Western Ghats of Karnataka and Kerala.
  6. Agricultural Evolution

    Transition from post-independence subsistence to the Green Revolution and modern sustainable practices.

    • Green Revolution Package — 1960s 'package technology' using HYV seeds (Wheat/Rice), chemical fertilizers, and pesticides with assured irrigation.
    • Planning & Liberalization — 1980s-90s shift toward agro-climatic planning for rainfed areas and crop diversification.
    • Sustainable Agriculture — Modern focus on National Mission for Sustainable Agriculture (NMSA) and organic farming (PKVY).
  7. Challenges & Constraints

    Physical, institutional, and environmental problems that limit the productivity and sustainability of Indian farming.

    • Monsoon & Fragmentation — Erratic rainfall (only 33% irrigation) and small, scattered landholdings make farming uneconomic.
    • Environmental Degradation — Faulty irrigation causes salinisation and waterlogging; excessive chemicals create toxic soil profiles.
    • Resource Depletion — Displacement of legumes has reduced natural nitrogen fixation, leading to depleted soil fertility.

Chapter notes

An in-depth study of India's land-use patterns, agricultural systems, and the evolution of farming practices from independence to the modern era, focusing on resource management and sustainability.

Understanding Land Use Categories

Land is a finite resource used for production, residence, and recreation. In India, land-use records are maintained by the Land Revenue Department, which tracks the 'reporting area'.

The reporting area differs from the geographical area measured by the Survey of India. While geographical area remains fixed, reporting area can vary based on revenue estimates. Land is classified into several categories including forests, barren lands, and area under non-agricultural uses like infrastructure and settlements.

A critical distinction exists between 'area classified as forest' and 'actual forest cover'. The former refers to land demarcated by the government for forest growth in revenue records (page 1). Barren and wastelands (page 1) include hilly terrains or deserts that cannot be cultivated with current technology. Land put to non-agricultural uses (page 2) includes settlements, roads, and industries.

Fallow Lands and Culturable Wasteland

Not all land is used every year; some is left to rest to regain fertility, while other land remains unutilized due to various constraints.

Fallow land is divided into 'Current Fallow' and 'Fallow other than Current Fallow'. Current fallow is land left uncultivated for one or less than one agricultural year to recoup fertility naturally. Fallow other than current fallow is land left uncultivated for more than one year but less than five years.

If land remains uncultivated for more than five years, it is categorized as 'Culturable Wasteland'. This land is potentially productive but requires reclamation practices to be brought back into the cropping cycle. Net Sown Area (NSA) represents the actual physical extent of land where crops are sown and harvested.

Classification of Uncultivated Land by Duration

  1. 1

    Current Fallow

    Left uncultivated for 1 year or less to restore soil nutrients.

  2. 2

    Other Fallow

    Left uncultivated for more than 1 year but less than 5 years.

  3. 3

    Culturable Wasteland

    Left uncultivated for more than 5 years; requires reclamation.

Common Property Resources (CPRs)

Land ownership in India is broadly classified into private land and Common Property Resources (CPRs).

CPRs are owned by the state or the community rather than individuals. Every member of the community has access rights and usage obligations. Examples include community forests, village pastures, and water bodies. These resources are vital for the rural economy as they provide fodder for livestock and fuel for households.

CPRs are particularly important for landless farmers and marginalized sections who depend on livestock for income. They also play a significant role in the lives of rural women, who are typically responsible for collecting fuel and fodder. However, many CPRs are currently facing degradation due to over-exploitation.

Cropping Intensity and Agricultural Seasons

In a land-scarce country like India, increasing the productivity of existing land is essential. This is measured through cropping intensity.

Cropping Intensity (CI) measures how many times a piece of land is used in a single year. It is calculated by dividing the Gross Cropped Area (GCA) by the Net Sown Area (NSA) and multiplying by 100. A higher CI indicates more efficient land use and higher demand for agricultural labor.

India has three distinct cropping seasons: Kharif, Rabi, and Zaid. Kharif coincides with the Southwest Monsoon (June-September), featuring tropical crops like rice and cotton. Rabi (October-March) involves temperate crops like wheat and gram. Zaid is a short summer season (April-June) for vegetables and fruits. In Southern India, high temperatures allow tropical crops to grow year-round if moisture is available.

Calculating Cropping Intensity

CI = (GCA / NSA) * 100

If a farmer has 5 hectares of land (NSA) but grows crops on all 5 hectares in Kharif and only 3 hectares in Rabi, the Gross Cropped Area (GCA) is 8 hectares. CI = (8 / 5) * 100 = 160%.

Major Foodgrains: Cereals

Foodgrains occupy about two-thirds of India's total cropped area and are classified into cereals and pulses.

Rice is the staple food for most Indians. India contributes 22.07 per cent of rice production in the world and ranked second after China in 2018. While it is a tropical humid crop, irrigation has allowed its growth in dry areas like Punjab and Haryana. In West Bengal, farmers grow three crops of rice: 'aus', 'aman', and 'boro'.

Wheat is the second most important cereal, primarily grown in the Rabi season in temperate zones. It is concentrated in the Indo-Gangetic Plain and Malwa Plateau. Jowar is a major food crop in semi-arid areas of Central and Southern India (page 8), with Maharashtra being the leading producer. Other cereals include coarse grains like Bajra and Maize.

Pulses and Oilseeds

Pulses provide essential proteins for vegetarians, while oilseeds are the primary source of edible oils.

India is a leading producer of pulses, which are legume crops that improve soil fertility through nitrogen fixation. Gram and Tur (Arhar) are the main pulses. Gram is a Rabi crop grown in subtropical areas, while Tur is a Kharif crop often grown on marginal lands in central and southern states.

Oilseeds occupy about 14% of the total cropped area. Groundnut is a major rainfed Kharif crop, with Gujarat and Rajasthan being top producers. Rapeseed and Mustard are frost-sensitive Rabi crops. Other important oilseeds include Soyabean (page 10), concentrated in MP and Maharashtra, and Sunflower (page 12), grown mainly in Karnataka and Telangana.

Fibre and Plantation Crops

These crops are grown primarily for industrial use and export, providing raw materials for textiles and beverages.

Cotton is a tropical Kharif crop grown in semi-arid areas. India ranks second globally in production. It requires a clear sky during the flowering stage. Major areas include the northwest (Punjab, Haryana), the west (Gujarat, Maharashtra), and the southern plateaus. Jute is a cash crop concentrated in West Bengal, used for making bags and decorative items.

Tea and Coffee are major plantation crops. Tea was introduced in the 1840s in the Brahmaputra valley of Assam, which remains the top producer. Coffee is grown in the Western Ghats of Karnataka, Kerala, and Tamil Nadu. India primarily grows the high-quality 'arabica' variety, which is in high demand internationally.

Agricultural Development and the Green Revolution

Post-independence, India shifted from a subsistence-based agricultural economy to one focused on self-reliance through technology.

The Green Revolution, launched in the mid-1960s, introduced 'package technology'. New seed varieties of wheat (Mexico) and rice (Philippines) known as high yielding varieties (HYVs) were available for cultivation. This strategy included chemical fertilizers and pesticides, all supported by assured irrigation, and was initially successful in Punjab, Haryana, and Western UP.

While the Green Revolution made India self-reliant in foodgrains, it initially led to regional disparities. In the 1980s and 90s, planning shifted toward rainfed areas and crop diversification. Modern policies now emphasize sustainable agriculture through missions like the National Mission for Sustainable Agriculture (NMSA) and organic farming schemes like PKVY.

Challenges and Problems in Indian Agriculture

Despite significant growth, Indian agriculture faces several structural and environmental constraints.

A major physical constraint is the dependence on the erratic monsoon, as only about 33% of cultivated land is irrigated. This leads to low productivity compared to international standards. Institutional issues include the lack of effective land reforms and the fragmentation of landholdings, which makes farming uneconomic for small and marginal farmers.

Environmental degradation is a rising concern. In irrigated areas, faulty strategies have led to soil alkalisation, salinisation, and waterlogging. Excessive use of chemicals has created toxic soil profiles. Furthermore, the displacement of leguminous crops has reduced natural nitrogen fixation, leading to a depletion of soil fertility.

Problem TypeSpecific IssueConsequence
PhysicalErratic MonsoonVulnerability to droughts and floods
InstitutionalSmall Farm SizeUneconomic production and low investment
FinancialIndebtednessHigh interest traps and farmer distress
