Gross cropped area

Also called: Total cropped area, GCA · Topic: Land Use, Farming Systems and Cropping Seasons in India · NCERT: Class 10, Ch 1 "Resources and Development"; Class 12, Ch 3 "Land Resources and Agriculture"

Meaning

Gross cropped area (GCA), also called total cropped area, is the total area sown with crops in one agricultural year, where a field is counted once for each crop grown on it. If a field grows two crops in a year, it is counted twice.

India has very little new land left to farm. So GCA shows how much more food and work India gets by sowing the same land more than once.

Explanation

How GCA is counted

• Basic formula: GCA = net sown area + area sown more than once in the year.
• Net sown area (NSA) is the land sown with crops and orchards in a year. Each field is counted only once, even if it is sown twice.

• GCA counts the field again for every extra crop.

• Worked example:

• A 1-hectare field grows rice in kharif (the monsoon season) and wheat in rabi (the winter season).

• NSA = 1 ha. GCA = 2 ha.

• So GCA is always equal to or bigger than NSA.

• The gap between them (GCA − NSA) is the area sown more than once.
• This gap measures how much multiple cropping (growing two or more crops on the same field in one year) takes place.

Cropping intensity: the ratio built on GCA

• Cropping intensity = (GCA ÷ NSA) × 100. It shows how many times, on average, the same land is cropped in a year.
• 100% means one crop a year.
• 200% means two crops a year on every field.

• 300% means three crops a year.

• All-India trend: it rose from 142.2% in 2014-15 to 159.7% in 2024-25 [2]. Older books give about 150-155%.

• Dividing GCA by cropping intensity gives an NSA of about 141 million ha in 2024-25.
• So nearly 59.7% of the sown land carried a second crop.

Why GCA keeps rising while NSA cannot

• Little room to farm new land:
• Total cultivable land fell from 59.5% (1950-51) to 57.7% (2019-20) of reporting area.
• Culturable wasteland (land that could be farmed but has been unused for more than 5 years) fell from 13.4% to 6.8% of cultivable land.

• NSA rose from 70.0% to 79.0% of cultivable land. Most of the spare land is already being farmed.

• So growth comes from sowing the same land more often:

• GCA rose from 198.28 million ha (2014-15) to 225.19 million ha (2024-25), according to Land Use Statistics 2024-25 [2].
• Total cropped area rose from 201.18 million ha (2018-19) to 219.16 million ha (2021-22) [3].

• Almost all of this rise came from sowing the same land more than once.

• This is a land-saving technology (any method that gets more output from the same area). It raises total output per hectare per year, not only the yield of one crop.

Conditions needed for a high GCA

• Irrigation is the key driver. Without water after the monsoon, the rabi field stays fallow (left unsown).
• Short-duration seeds: after the mid-1960s, Green Revolution high-yielding variety (HYV) wheat and rice ripened faster. This left time for a second crop.
• Tube wells and canals gave water in the dry season. Together with HYV seeds, they let farmers grow a rabi crop (wheat) after a kharif crop (rice).
• Labour: each extra season needs more ploughing, sowing, weeding and harvesting. India has many farm workers, so a high GCA suits it.

Where it occurs

• High GCA compared with NSA (high cropping intensity):
• Punjab (near 190%), Haryana and West Bengal. They have assured irrigation from canals and tube wells, HYV seeds, and rice-wheat or rice-rice-potato sequences.

• Punjab, Haryana and western Uttar Pradesh, where the Green Revolution rice-wheat system grows two crops on the same field.

• Low GCA compared with NSA (low cropping intensity):

• Dry Rajasthan and Gujarat (Kachchh), where there is no water for a second season.
• The rain-fed Deccan plateau, which has poor soils and little water after the monsoon.

• Hill states, where the cold leaves a short growing season.

• Eastern India: relay cropping (utera/paira) adds a second crop. Lentil or gram is sown into a standing rice crop before it is harvested.

• Ancient example: at Kalibangan (a Harappan site on the Ghaggar river, Hanumangarh district, Rajasthan), a ploughed field with furrows crossing at right angles shows that two crops were grown together about 4,500 years ago.
• Data source: GCA figures for India come from the Land Use Statistics of the Ministry of Agriculture and Farmers Welfare [2].

Don't confuse with

• Net sown area (NSA): counts a field only once in a year. GCA counts it once for each crop. So GCA ≥ NSA always.
• Cropping intensity: this is a ratio in % (GCA ÷ NSA × 100). GCA is an area in hectares.
• Total cultivable land: this is NSA + current fallow + other fallow + culturable wasteland. It measures land that can be farmed, not land that was actually sown, and it does not count a field twice.
• Yield per hectare: this is output from one crop on one hectare. A rise in GCA means more crops a year on the same land, not a bigger harvest from each crop.

Prelims Hooks

• GCA = NSA + area sown more than once. A 1-ha field with rice (kharif) and wheat (rabi) gives NSA = 1 ha and GCA = 2 ha.
• Cropping intensity = GCA ÷ NSA × 100. It rose from 142.2% (2014-15) to 159.7% (2024-25), while GCA rose from 198.28 to 225.19 million ha [2].
• Total cropped area: 201.18 million ha (2018-19) → 219.16 million ha (2021-22) [3].
• Trap: a statement saying "NSA can be larger than GCA" is wrong. GCA is always equal to or larger than NSA.
• Highest cropping intensity: Punjab (about 190%). Lowest: arid Rajasthan, Kachchh, the rain-fed Deccan and hill states.
• Section 10 of the RFCTLARR Act, 2013 limits the acquisition of multi-crop irrigated land, which is the land that adds most to GCA [2].

Mains Points

• Growth must come from sowing the same land again (GS-III):
• Cultivable land is shrinking (59.5% → 57.7%), and culturable wasteland is almost used up (13.4% → 6.8%).
• GCA still rose by about 27 million ha in a decade (2014-15 to 2024-25) [2], almost all of it from double cropping.

• This brings more food and more rural jobs. It also cuts disguised unemployment (more people working on a farm than are really needed).

• Regional gaps depend on irrigation:

• GCA is far above NSA in the Punjab-Haryana plains but close to NSA in rain-fed Rajasthan, the Deccan and the hills.
• More micro-irrigation, such as Per Drop More Crop under PM-RKVY [2], can make a second season possible in these dry areas.

• Multi-crop irrigated land must also be protected. Land is a State subject (Entry 18, List II) [2], and the RFCTLARR Act, 2013 requires a Social Impact Assessment and restricts taking such land under Section 10 [2].

• The hidden cost of a high GCA:

• Continuous rice-wheat cropping has shortened fallow periods and pushed out legumes (pulses that add nitrogen to the soil).
• The soil loses its natural fertility, and farmers depend more on chemical fertilisers.
• Answers should suggest crop rotation with pulses, crop diversification and soil health cards.
