Irrigation, the Green Revolution and new directions

ಕನ್ನಡದಲ್ಲಿ ವಿವರಣೆ

Agriculture of India · Part 4 / 4 · Fact-checked on · how we check

Written with AI from the sources listed at the bottom of this page, then fact-checked by a separate AI.

Canals, wells and tube wells, and tanks, and where each dominates; groundwater stress and the CGWB categories; drip, sprinklers and PMKSY; the Green Revolution, its package, its gains and its costs; dryland farming and watershed development; organic and natural farming.

Each idea is explained first in Kannada (ಕನ್ನಡ), ending with the English and Hindi exam terms, followed by the same point in exam English. UPSC Prelims is in English or Hindi, so understand it in Kannada and revise it in English.

ಇಲ್ಲಿಯವರೆಗೆ ಭೂಮಿ ಮತ್ತು ಯಾವ ಬೆಳೆ ಎಲ್ಲಿ ಬೆಳೆಯುತ್ತದೆ ಎಂದು ನೋಡಿದೆವು. ಈಗ ಹೊಲಕ್ಕೆ ನೀರು ಹೇಗೆ ಬರುತ್ತದೆ, 1960ರ ನಂತರ ಕೃಷಿ ಹೇಗೆ ಬದಲಾಯಿತು ಎಂಬುದು. ಮಳೆ ಕೆಲವೇ ತಿಂಗಳು, ಅದೂ ವರ್ಷದಿಂದ ವರ್ಷಕ್ಕೆ ಬೇರೆ; ಮಳೆಯನ್ನೇ ನಂಬಿದ ಹೊಲ ಜೂಜಿನಂತೆ. ನೀರಾವರಿ ಇದ್ದರೆ ಚಳಿಗಾಲದಲ್ಲಿ ಎರಡನೇ ಬೆಳೆ, ಬೆಳೆ ತೀವ್ರತೆ ಹೆಚ್ಚುತ್ತದೆ, ದುಬಾರಿ ಬೀಜ, ಗೊಬ್ಬರ ಕೊಳ್ಳುವುದು ಲಾಭ. ಅದಕ್ಕೇ ಹಸಿರು ಕ್ರಾಂತಿ ನೀರು ಖಚಿತವಿದ್ದಲ್ಲೇ ಶುರುವಾಯಿತು. ಅದಕ್ಕೆ ಬೆಲೆಯೂ ಇದೆ: ಆಳಕ್ಕೆ ಹೋದ ನೀರಿನ ಮಟ್ಟ, ದಣಿದ ಮಣ್ಣು. ಈಗ ಹೊಸ ದಾರಿಗಳು: ನೀರಿನ ಉಳಿತಾಯ, ಒಣ ಭೂಮಿಗೆ ಜೀವ, ಕಡಿಮೆ ರಾಸಾಯನಿಕ. (→ English: cropping intensity; Green Revolution · हिन्दी: शस्य गहनता; हरित क्रांति)

In exam EnglishParts 1 to 3 showed how India uses its farmland and which crops grow where. This last part asks two further questions: how do farmers get water to their fields, and how did farming change after the 1960s? Indian rain arrives in a few monsoon months and swings from year to year, so a field that waits only for rain is always a gamble. It allows a second crop in the dry winter, raises cropping intensity and makes costly seed and fertiliser worth buying. That is why the Green Revolution began where water was assured. The story also has a cost side, in sinking water tables and worn-out soils, and a search for new directions: saving water, reviving dry land and farming with fewer chemicals.

ಹೊಲಕ್ಕೆ ನೀರು ನಾಲ್ಕು ದಾರಿಗಳಲ್ಲಿ ಬರುತ್ತದೆ. ಕಾಲುವೆ: ಅಣೆಕಟ್ಟಿನಿಂದ ನದಿ ನೀರು. ಬಾವಿ, ಕೊಳವೆಬಾವಿ: ನೆಲದೊಳಗಿನ ನೀರು, ಪಂಪಿನಿಂದ ಮೇಲಕ್ಕೆ. ಕೆರೆ: ಮಳೆನೀರನ್ನು ಏರಿ ಕಟ್ಟಿ ತಡೆಯುವುದು; ನಮ್ಮೂರ ಕೆರೆಯಂತೆ. ಇಂದು ನೀರಾವರಿಯ ಅರ್ಧಕ್ಕಿಂತ ಹೆಚ್ಚು ಅಂತರ್ಜಲದಿಂದಲೇ. ಏಕೆ? ಕಾಲುವೆ ನೀರು ಸರದಿಯಂತೆ ಬರುತ್ತದೆ, ಕೊನೆಯ ಹೊಲಕ್ಕೆ ಹಲವು ಬಾರಿ ತಲುಪುವುದಿಲ್ಲ; ಆದರೆ ಪಂಪಿನ ಸ್ವಿಚ್ ರೈತನ ಕೈಯಲ್ಲಿ. ವಿದ್ಯುತ್ ಅಗ್ಗ ಅಥವಾ ಉಚಿತವಾದರೆ ಇನ್ನೂ ಸುಲಭ. (→ English: groundwater; canal, tube well, tank · हिन्दी: भूजल; नहर, नलकूप, तालाब)

In exam EnglishIndian farmers draw water from four kinds of source. Canals lead river water away from a dam or barrage. Wells and tube wells pump up water stored underground. Tanks are small reservoirs, made by raising an earthen bank across a slope or a stream to hold monsoon run-off. The Ministry of Agriculture's land-use figures show that wells and tube wells together water more than half of the net irrigated area, with canals a distant second and tanks a small and shrinking share. groundwater won because the farmer controls it: a pump can be switched on the very day a crop needs water, whereas canal water comes by a fixed turn and often runs short at the tail end of the network. Cheap or free electricity for farm pumps in many states made pumping cheaper still.

ಎಲ್ಲಿ ಯಾವ ಜಲಮೂಲ ಎಂಬುದು ನೆಲ, ಬಂಡೆ, ನದಿಯನ್ನು ಅವಲಂಬಿಸಿದೆ. ಉತ್ತರದ ಬಯಲಿನಲ್ಲಿ ಹಿಮ ಕರಗಿ ಹರಿಯುವ ನದಿಗಳು, ಸಮತಟ್ಟು ನೆಲ; ಅದಕ್ಕೇ ಕಾಲುವೆಗಳು; ಪೂರ್ವ ಕರಾವಳಿಯ ಮುಖಜ ಭೂಮಿಯಲ್ಲೂ ಕಾಲುವೆ. ಪಂಜಾಬ್, ಹರಿಯಾಣದಲ್ಲಿ ಆಳವಾದ ಮರಳು, ಮೆಕ್ಕಲು ಪದರಗಳಲ್ಲಿ ಬಹಳ ನೀರು, ಕೊಳವೆಬಾವಿ ಸುಲಭ. ನಮ್ಮ ಕರ್ನಾಟಕದಂಥ ದಕ್ಷಿಣ ಪ್ರಸ್ಥಭೂಮಿಯಲ್ಲಿ ಗಟ್ಟಿ ಬಂಡೆ, ಒಳಗೆ ನೀರು ಕಡಿಮೆ, ಹಳ್ಳಗಳು ಬತ್ತುತ್ತವೆ; ಅದಕ್ಕೇ ಊರಿಗೊಂದು ಕೆರೆ. ದೇಶದ ಬಿತ್ತನೆ ಭೂಮಿಯ ಸುಮಾರು ಅರ್ಧಕ್ಕೆ ಮಾತ್ರ ನೀರಾವರಿ. (→ English: canal, tube well, tank irrigation · हिन्दी: नहर, नलकूप, तालाब सिंचाई)

In exam EnglishWhich source leads in a region depends on its relief, its rock and its rivers. Canals lead in the flat northern plains fed by Himalayan rivers, in Punjab, Haryana and Uttar Pradesh, and in the east-coast deltas of the Godavari, the Krishna and the Kaveri. Tube wells lead across the alluvial plains of Punjab, Haryana and western Uttar Pradesh, because deep beds of sand and silt hold plenty of water that is easy to bore into. Tanks belong to the southern plateau, in Tamil Nadu, Telangana, Andhra Pradesh and Karnataka. There the hard crystalline rock stores little water below ground, most streams dry up after the rains and the rolling land makes it easy to bank up small valleys. Across the country, roughly half of the net sown area is irrigated.

(→ English: stage of groundwater extraction; saline and alkaline soil · हिन्दी: भूजल निष्कर्षण का चरण; लवणीय और क्षारीय मृदा)

In exam EnglishThe spread of tube wells has a price: in many districts more water is pumped out each year than the rain puts back. The Central Ground Water Board, working with the states, rates every assessment unit by its stage of extraction, meaning the share of the yearly extractable recharge that is actually drawn out. A unit counts as safe up to 70 percent, semi-critical from 70 to 90, critical from 90 to 100 and over-exploited above 100 percent. Critical and over-exploited units are concentrated in the rice and wheat lands of Punjab and Haryana, in Rajasthan and Delhi, and in hard-rock parts of Tamil Nadu and Karnataka. Canal areas can suffer the opposite fault. Heavy watering with poor drainage lifts the water table, leaving fields waterlogged and crusted with the salts of saline and alkaline soil, as in parts of the Indira Gandhi Canal command in Rajasthan.

(→ English: micro-irrigation; Per Drop More Crop · हिन्दी: सूक्ष्म सिंचाई; प्रति बूँद अधिक फ़सल)

In exam EnglishOne response is to make each drop go further. In micro-irrigation, water reaches the plant through pipes instead of flooding the whole field. Drip irrigation lets water fall slowly at the root through small emitters, and suits widely spaced crops such as fruit trees, vegetables, cotton and sugarcane; fertiliser can be dissolved in the same water, a practice called fertigation. Sprinklers spray water over the crop like light rain and suit close-growing crops on sandy or uneven ground, where flooding a field wastes water. Both save water and labour but cost money up front, so governments subsidise them. The Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), approved in 2015, brought the irrigation schemes together under two slogans, 'Har Khet Ko Pani' (water to every field) and 'Per Drop More Crop'. Per Drop More Crop is its micro-irrigation part.

(→ English: high-yielding variety (HYV); Green Revolution · हिन्दी: अधिक उपज देने वाली किस्म; हरित क्रांति)

In exam EnglishIn the mid-1960s India was importing large amounts of wheat, much of it from the United States, and the droughts of 1965 and 1966 made the shortage acute. The answer was a package. At its centre was high-yielding variety (HYV) seed: short-stemmed (dwarf) wheat that grew out of Norman Borlaug's breeding work in Mexico, and later rice such as IR8 from the International Rice Research Institute in the Philippines. These plants give their big harvests only with heavy doses of chemical fertiliser, timely and assured water, and pesticides. Indian scientists led by M. S. Swaminathan tested and adapted the seeds, and the government added cheap credit, guaranteed prices and public purchase; the Agricultural Prices Commission and the Food Corporation of India were both set up in 1965. In 1968 the American official William Gaud gave the change the name Green Revolution. Because the package depended on water, it took root first in the irrigated wheat lands of Punjab, Haryana and western Uttar Pradesh; rice followed later.

ಲಾಭ ದೊಡ್ಡದೇ: ಗೋಧಿ ಉತ್ಪಾದನೆ ವೇಗವಾಗಿ ಏರಿತು, 1970ರ ಆರಂಭದಲ್ಲೇ ವಿದೇಶಿ ಆಹಾರ ನೆರವಿನ ಅಗತ್ಯ ಹೋಯಿತು, ಗೋದಾಮುಗಳ ಧಾನ್ಯ ದಾಸ್ತಾನು ಪಡಿತರ ಅಂಗಡಿಗಳಿಗೆ ಆಧಾರವಾಯಿತು. ಆದರೆ ಹಂಚಿಕೆ ಅಸಮಾನ. ಮದುವೆ ಊಟದಲ್ಲಿ ಮೊದಲ ಪಂಕ್ತಿಗೇ ಎಲ್ಲ ಸಿಕ್ಕಂತೆ: ಪ್ರದೇಶದಲ್ಲಿ ನೀರಾವರಿಯ ವಾಯವ್ಯ ಮುಂದೆ, ಮಳೆಯಾಶ್ರಿತ ಮಧ್ಯ ಭಾರತ, ಪೂರ್ವ ರಾಜ್ಯಗಳು ಹಿಂದೆ; ಬೆಳೆಯಲ್ಲಿ ಗೋಧಿ, ಭತ್ತ ಮುಂದೆ, ಬೇಳೆ, ಎಣ್ಣೆಕಾಳು, ಸಿರಿಧಾನ್ಯ ಹಿಂದೆ; ರೈತರಲ್ಲಿ ಭೂಮಿ, ಬಾವಿ, ಸಾಲ ಇದ್ದವರು ಮುಂದೆ. ಪೂರ್ವಕ್ಕೆ ಕೊಂಡೊಯ್ಯಲು 2010–11ರಲ್ಲಿ ಹೊಸ ಕಾರ್ಯಕ್ರಮ. (→ English: regional imbalance; Bringing Green Revolution to Eastern India · हिन्दी: क्षेत्रीय असंतुलन; पूर्वी भारत में हरित क्रांति लाना)

In exam EnglishThe gains were large. Wheat output climbed steeply within a few years, by the early 1970s India no longer relied on food aid, and the government could build up grain stocks that later backed the public distribution system. Yet the benefits were uneven in three ways. Between regions, the irrigated north-west raced ahead while rain-fed central India, the dry peninsula and the eastern states with poor water control gained far less. Between crops, wheat and rice received most of the research, price support and procurement, while pulses, oilseeds and millets lagged. Between farmers, those with land, wells and access to credit adopted the package first. To carry the gains eastward, the Centre started Bringing Green Revolution to Eastern India in 2010–11, aimed at the rice lands of states such as Bihar, Odisha, West Bengal, Assam and eastern Uttar Pradesh.

(→ English: stubble burning; neem-coated urea · हिन्दी: पराली जलाना; नीम-लेपित यूरिया)

In exam EnglishHalf a century on, the costs are plainest where the change began. Two thirsty cereals, paddy in summer and wheat in winter, follow each other on the same fields year after year, so groundwater sinks and soils lose organic matter. Fertiliser use is lopsided: nitrogen from urea, the most heavily subsidised and so the cheapest, is applied far more than phosphorus and potash, against a balance usually given as 4:2:1 for nitrogen, phosphorus and potassium, and shortages of micronutrients such as zinc have spread. After combine harvesters cut the paddy, the short gap before wheat sowing leads many farmers to burn the loose straw in October and November, adding to the winter smog over Delhi and the northern plains. The responses include coating all urea with neem oil from 2015 to curb its misuse, soil health cards, machines that sow wheat straight into the paddy stubble, and incentives to move part of the paddy land to other crops.

(→ English: dryland farming; watershed development · हिन्दी: शुष्क भूमि कृषि; जलसंभर विकास)

In exam EnglishAbout half of India's farmland has no irrigation and lives by the monsoon. These rain-fed lands grow most of the country's pulses, millets and oilseeds and much of its cotton. Geographers often separate dryland farming, practised where yearly rain is below about 75 cm and the whole aim is to hold on to soil moisture, from rain-fed farming in wetter areas where the rain is usually enough. The main tool for such land is the watershed, the entire area that drains to one stream or outlet. watershed development treats that area as a unit, from the ridge down to the valley: contour bunds and trenches on the slopes, check dams across the streams, farm ponds, trees on bare land, and mulching and hardy crops in the fields, so that rain soaks in instead of rushing off with the topsoil. The Integrated Watershed Management Programme of 2009–10 now runs as the watershed component of PMKSY under the Department of Land Resources.

ಸಾವಯವ ಕೃಷಿ ಎಂದರೆ ರಾಸಾಯನಿಕ ಗೊಬ್ಬರ, ಕೀಟನಾಶಕ ಇಲ್ಲದೆ: ಕಾಂಪೋಸ್ಟ್, ಹಸಿರೆಲೆ ಗೊಬ್ಬರ, ಬೆಳೆ ಪರಿವರ್ತನೆಯಿಂದ ಮಣ್ಣಿನ ಫಲವತ್ತತೆ. ಹೊರಗಿನಿಂದ ಕೊಳ್ಳಬಹುದು, ಆದರೆ ನೈಸರ್ಗಿಕವಾದದ್ದೇ.

(→ English: organic farming · हिन्दी: जैविक खेती)

In exam EnglishA further direction is to farm with fewer chemicals. organic farming does without synthetic fertilisers and pesticides and keeps the soil fertile with compost, green manure, crop rotation and biological pest control; inputs may be bought from outside the farm so long as they come from natural sources. Produce can be sold as organic only after certification. The National Programme for Organic Production (2001), run through APEDA, covers exports, and a cheaper group-based Participatory Guarantee System serves buyers at home. The Paramparagat Krishi Vikas Yojana (2015) helps farmers who convert together in clusters. Sikkim was declared India's first fully organic state in January 2016, after phasing out chemical fertilisers and pesticides over more than a decade. Yields often fall in the first years after conversion.

(→ English: natural farming · हिन्दी: प्राकृतिक खेती)

In exam Englishnatural farming goes a step further and buys almost nothing from outside. Farmers prepare their own inputs from cow dung and urine, jaggery, pulse flour and a handful of soil, such as jeevamrit to feed the soil's microbes and beejamrit to treat seed; they keep the ground covered with mulch and grow several crops together on the same plot. The approach was popularised in India by Subhash Palekar as 'zero budget natural farming', and Andhra Pradesh has run the largest state programme. On 25 November 2024 the Union Cabinet approved a separate National Mission on Natural Farming with an outlay of Rs 2,481 crore, meant to reach about one crore farmers through clusters and village bio-input resource centres. The difference to keep clear is simple: organic farming may use bought organic inputs and is certified, whereas natural farming depends on inputs made on the farm itself.

(→ English: Green Revolution · हिन्दी: हरित क्रांति)

In exam EnglishTaken together, the four parts tell a single story. Land and seasons, from Part 1, decide what can be grown; the crops of Parts 2 and 3 show where; and water and technology, the subject of this part, largely decide how much. Irrigation, above all from groundwater, made the Green Revolution possible and turned India from a country waiting for food ships into one with large grain stocks and rice to export. The same model has left the north-west short of water and its soils overworked, while the rain-fed half of the country gained the least. The newer directions, saving water through drip and sprinklers, healing dry land through watersheds, and cutting chemicals through organic and natural farming, try to keep the gains while repairing the damage.

Recap

Practice questions

Q1. Which one of the following is the largest source of net irrigated area in India?

  1. Canals
  2. Tanks
  3. Wells and tube wells
  4. Lift irrigation from rivers
Show answer

Answer: C. Wells and tube wells

Wells and tube wells together water more than half of the net irrigated area. Canals are a distant second, tanks are a small and shrinking share, and river-lift schemes fall in the small 'other sources' group.

Q2. Tank irrigation is most common in the southern peninsular plateau. Which of the following explain this?
1. The hard crystalline rock stores little groundwater.
2. Most streams are seasonal and dry up after the rains.
3. Thick alluvial deposits make boring wells difficult.
Select the correct answer using the code given below.

  1. 1 and 2 only
  2. 2 and 3 only
  3. 1 and 3 only
  4. 1, 2 and 3
Show answer

Answer: A. 1 and 2 only

Statements 1 and 2 are correct. Statement 3 is wrong: thick alluvium is a feature of the northern plains, and it makes boring EASY, which is why tube wells lead there. So every option containing 3 is wrong.

Q3. Under the Central Ground Water Board's categorisation, an assessment unit whose annual extraction is 95 percent of its annual extractable groundwater recharge is classified as:

  1. Safe
  2. Semi-critical
  3. Critical
  4. Over-exploited
Show answer

Answer: C. Critical

Between 90 and 100 percent is 'critical'. 'Safe' is up to 70 percent and 'semi-critical' 70 to 90 percent, both below 95; 'over-exploited' begins only above 100 percent.

Q4. Consider the following statements about the Green Revolution in India:
1. It first succeeded with wheat in the irrigated north-west.
2. Its high-yielding varieties gave high yields even without assured irrigation or fertiliser.
Which of the statements given above is/are correct?

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2
Show answer

Answer: A. 1 only

Statement 1 is correct. Statement 2 is wrong: HYV seed pays off only with assured water and heavy fertiliser, which is exactly why the change began in irrigated areas. So '2 only' and 'both' accept a wrong statement, and 'neither' rejects a correct one.

Q5. Match List I with List II:
List I (Scheme or programme) — List II (Main aim)
A. Per Drop More Crop — 1. Cluster-based organic farming
B. Paramparagat Krishi Vikas Yojana — 2. Micro-irrigation
C. Bringing Green Revolution to Eastern India — 3. Ridge-to-valley treatment of land and water
D. Watershed Development Component of PMKSY — 4. Raising rice output in the eastern states
Select the correct answer using the code given below.

  1. A-2, B-1, C-4, D-3
  2. A-1, B-2, C-4, D-3
  3. A-2, B-1, C-3, D-4
  4. A-3, B-1, C-4, D-2
Show answer

Answer: A. A-2, B-1, C-4, D-3

Per Drop More Crop is the micro-irrigation part of PMKSY (A-2), PKVY supports organic farming in clusters (B-1), BGREI targets the eastern rice lands (C-4) and the watershed component treats land from ridge to valley (D-3). The second option swaps A and B, the third swaps C and D, and the fourth gives Per Drop More Crop to watersheds.

Q6. Consider the following statements:
1. Sikkim was declared India's first fully organic state in January 2016.
2. Natural farming, unlike certified organic farming, relies mainly on inputs prepared on the farm, such as jeevamrit.
Which of the statements given above is/are correct?

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2
Show answer

Answer: C. Both 1 and 2

Both statements are correct: Sikkim became fully organic in January 2016, and natural farming depends on farm-made inputs while organic farming may use bought organic inputs and is certified. '1 only' and '2 only' each reject a correct statement, and 'neither' rejects both.

Q7. Which one of the following is NOT generally counted among the ecological costs of the Green Revolution in north-western India?

  1. Falling groundwater tables
  2. Deficiency of micronutrients such as zinc
  3. Burning of paddy straw before wheat sowing
  4. Expansion of shifting cultivation
Show answer

Answer: D. Expansion of shifting cultivation

Shifting cultivation is a hill and forest practice of the north-east and central tribal belts and has nothing to do with the Green Revolution. Falling water tables, zinc deficiency and stubble burning are all well-known costs of the rice–wheat system of the north-west.

Q8. Consider the following statements about micro-irrigation:
1. Drip irrigation is especially suited to widely spaced crops such as fruit trees.
2. Fertiliser can be supplied through drip lines, a practice known as fertigation.
3. Sprinkler irrigation is unsuitable for sandy soils.
Which of the statements given above are correct?

  1. 1 and 2 only
