Resource and Human Geography of Rajasthan

This chapter answers the Prelims Geography of Rajasthan items on soil, agriculture, livestock, irrigation, population (growth, density, literacy, sex ratio), urbanization, tribes, minerals and tourism, and the clause on agriculture and animal husbandry in Science and Technology with special reference to Rajasthan. For the Mains it answers Paper II, Unit III, Part C on soil, agriculture, mineral resources, demographic characteristics, tribes, ‘UNESCO Geo-parks and Geo-heritage sites: Potential in Rajasthan’ and tourism. It teaches how soil, water and rock decide where crops, minerals and people are found. Population figures are those of Census 2011; production shares change every year and are taught as patterns.

1. Soils and their problems

Soil in Rajasthan follows the same west-to-east and north-to-south gradient as rainfall. The west has sandy desert (arid) soils that are low in organic matter and hold little water. The east has alluvium, the Hadoti plateau has black soil, and the south has red and yellow soils on older rock.

Soil groups and where they occur
SoilWhereFeatures and crops
Desert (arid) soilJaisalmer, Barmer, Bikaner, Jodhpur, Churu, NagaurSandy, low in nitrogen; bajra, moth, guar, with irrigation wheat and cotton
Alluvial soilAlwar, Bharatpur, Dholpur, Karauli, Dausa, Sawai Madhopur, Tonk, parts of JaipurFertile; wheat, mustard, gram
Black soilHadoti: Kota, Bundi, Baran, JhalawarRetentive of moisture; soybean, cotton, oranges, coriander
Red and yellow soilUdaipur, Dungarpur, Banswara, ChittorgarhLighter, less fertile; maize, millets, pulses
Saline-alkaline soilLow basins of the west: lower Luni, Sambhar, Didwana beltsSalt crust; poor yield, needs gypsum and drainage
Hill (lithosol) soilAravalli slopesThin and stony; forest and pasture

The three chief soil problems are wind erosion in the dunes, salinity and waterlogging in the Indira Gandhi canal command, and gully erosion in the Chambal ravines. The Central Arid Zone Research Institute (CAZRI), set up at Jodhpur in 1959, works on dune stabilisation, shelter belts and arid farming.

2. Agriculture: seasons, crops and crop belts

Rajasthan has two main seasons. The kharif crops (sown with the monsoon, harvested October-November) are bajra, jowar, maize, moth, guar, groundnut, soybean and cotton. The rabi crops (sown October-November, harvested March-April) are wheat, barley, gram and mustard. Because rain is erratic and a large share of the sown area is unirrigated, output swings from year to year.

Rajasthan is among India's leading producers of bajra and rapeseed-mustard, grows most of India's guar and moth, and is the leading wool-producing state. The exact production share changes each year, so treat the rank as a pattern, not a fixed number. Licit opium poppy is a regulated crop of the Hadoti-Mewar belt, around Chittorgarh.

Crop belts
BeltCharacteristic crops
Western arid (Jaisalmer, Barmer, Jodhpur, Bikaner)Bajra, moth, guar; cumin in the Jodhpur-Barmer-Jalore-Nagaur belt; groundnut in Bikaner
Canal command (Sri Ganganagar, Hanumangarh)Wheat, cotton, mustard and kinnow
Eastern plains (Alwar, Bharatpur, Sawai Madhopur)Mustard, wheat, bajra
Hadoti (Kota, Bundi, Baran, Jhalawar)Soybean, wheat, coriander, oranges at Jhalawar
South (Udaipur, Banswara, Dungarpur, Bhilwara, Chittorgarh)Maize, pulses; poppy near Chittorgarh
🧠 Match crop to soil and rain
Pearl millet and guar tolerate sand and little rain, so they sit in the west. Wheat and cotton need irrigation, so they sit where the canal reaches. Soybean and coriander like retentive black soil, so they sit in Hadoti. If a crop seems out of place, ask what water and soil it needs.

3. Irrigation: canals, dams and traditional water harvesting

Wells and tubewells are the largest source of irrigation, and canals come second. Because the groundwater is over-drawn in many blocks, the state also depends on canals brought from outside the desert. The Indira Gandhi Canal is the key project: the idea was put forward by the engineer Kanwar Sain in the late 1940s, construction began in 1958 as the Rajasthan Canal, and it was renamed on 2 November 1984 after the death of Indira Gandhi. It starts from the Harike barrage at the confluence of the Sutlej and Beas in Punjab; the Rajasthan feeder (about 204 km) reaches Hanumangarh and the main canal (about 445 km) runs on through Bikaner to end near Jaisalmer, with branches reaching Barmer and other districts. Stage I and Stage II are commonly dated to 1983-86 and 2010 respectively.

Major irrigation and water projects
ProjectRiver or source and placeRegion served
Indira Gandhi CanalSutlej-Beas, from Harike barrageNorth-west: Hanumangarh to Jaisalmer, Barmer
Gang Canal (1927)Sutlej; built under Maharaja Ganga Singh of BikanerSri Ganganagar
Chambal projectChambal: Rana Pratap Sagar at Rawatbhata, Jawahar Sagar, Kota barrage (shared with Madhya Pradesh)Kota, Bundi and Baran
Mahi Bajaj SagarMahi, in BanswaraBanswara, Dungarpur
Bisalpur damBanas, in Tonk; completed 1999Drinking water for Jaipur and Ajmer; irrigation
Jawai damJawai, a Luni tributary, in PaliPali and the Marwar region

Traditional systems are part of the answer to scarcity. The tanka (a covered underground tank) and kund store roof and courtyard rain in Bikaner, Jodhpur and Jaisalmer; the khadin is an embanked farm that holds run-off to wet the soil for rabi sowing, associated with Jaisalmer; the johad is an earthen check-dam in Alwar district revived by community effort; baoris and jhalaras are stepwells for towns and temples.

⚠️ Harike is in Punjab
The Indira Gandhi Canal does not draw water from any river of Rajasthan. Its headworks are at Harike in Punjab, on the Sutlej and Beas. Do not confuse it with the Gang Canal (Sutlej, 1927, for Sri Ganganagar) or the Chambal project, which are separate.

4. Livestock, breeds and agricultural science

Livestock is the second pillar of the arid economy, and Rajasthan is the leading wool-producing state and the main home of the camel. The camel population has fallen between successive livestock censuses (about 2.13 lakh in Rajasthan in the 20th Livestock Census, 2019, against about 3.25 lakh in 2012), and the Rajasthan Camel (Prohibition of Slaughter and Regulation of Temporary Migration or Export) Act, passed in 2015, restricts slaughter and export of camels. Breeds are tied to regions, so recall them with the places.

Breeds and their regions
AnimalBreedRegion

GoatSirohi, JakhranaSirohi; Alwar
CamelBikaneri, JaisalmeriBikaner; Jaisalmer

Science supports the sector: CAZRI at Jodhpur (1959) for arid agriculture, the Central Sheep and Wool Research Institute at Avikanagar in Tonk district (1962) for sheep and wool, and a national research centre on the camel at Bikaner. The Swami Keshwanand Rajasthan Agricultural University at Bikaner and the agricultural university at Udaipur serve the arid and the southern belts.

5. Minerals, oil and power

The Aravalli is the mineral belt, and the western basins hold industrial and fuel minerals. Rajasthan is pre-eminent in quarrying and mining and is the source of white marble from Makrana (the stone of the Taj Mahal) and of the Jodhpur sandstone called Chittar Patthar.

Principal minerals and where they are worked
MineralChief places and districtsUse
Zinc and leadRampura Agucha (Bhilwara), Rajpura-Dariba (Rajsamand), Zawar (Udaipur)Galvanising, batteries, alloys
CopperKhetri (Jhunjhunu)Wire, alloys
SaltSambhar, Didwana, PachpadraEdible and industrial salt

LigniteBikaner (Palana), BarmerFuel for power
GypsumBikaner, Nagaur, JaisalmerCement, fertiliser, soil reclamation
Crude oilMangala and neighbouring fields, Barmer basin; discoveries from 2004Fuel, petrochemical feedstock

In power, the state has coal and lignite thermal stations (Kota, Suratgarh, Chhabra, Kalisindh), the Rawatbhata atomic power station on the Chambal reservoir in Chittorgarh, hydro stations on the Chambal and Mahi, and above all solar and wind capacity, because the state has clear skies, vast open land and strong winds. The Bhadla Solar Park in the Thar, with about 2,245 MW reported as commissioned by around 2020, is among the largest solar parks in the world; wind farms cluster around Jaisalmer. Capacity figures change every year, so check the date on any number.

⚠️ Khetri is copper, Zawar is zinc
Khetri in Jhunjhunu is the copper town. The zinc-lead mines are Zawar in Udaipur, Rajpura-Dariba in Rajsamand and Rampura Agucha in Bhilwara. Salt is from Sambhar, not from the lignite basin. Keep each mine tied to its mineral.

6. Population and urbanisation (Census 2011)

The Census of India has counted the people every ten years; the last full count for which the figures below are given is Census 2011, and a district-wise picture follows the 33-district map of that time. These figures stay valid until the next census is published.

Rajasthan at Census 2011
IndicatorFigure
Population68,548,437; about 5.7% of India; eighth-ranked state in Census 2011 (seventh after Telangana was formed in 2014)
DensityAbout 200 persons per sq km
Sex ratio928 females per 1,000 males (India 943)
LiteracyAbout 66%; female literacy among the lowest of all states
Urban shareAbout 24.9%
Scheduled Tribes9,238,534 persons, 13.48% of the population

District contrasts follow the physical map. Jaipur is the most populous district (about 66 lakh) and also among the densest (nearly 600 per sq km), while Jaisalmer is the least dense (about 17 per sq km). The lowest sex ratio is in Dholpur (about 845; Jaisalmer, at about 849, is also among the lowest). The sex ratio is highest in Dungarpur (just under 1,000), a tribal district. The desert districts of Bikaner, Jaisalmer and Barmer recorded the fastest decadal growth, above 30 per cent. Kota, with about 60 per cent urban population, is the most urbanised district. Literacy is highest in Kota and Jaipur (both about 76 to 77 per cent) and lowest in Jalore and Sirohi (about 55 per cent). Published district tables differ slightly in the decimals, so learn the order, not the decimal. The state's cities with a million or more people in Census 2011 were Jaipur, Jodhpur and Kota.

🎯 Why the desert grows fast but stays thin
The desert districts grew fastest because they started from very small bases and the canal brought settlers and farming to the north-west. They stay thinly peopled because water, not land, limits settlement. The densest districts sit on the alluvium of the east and on the Jaipur urban core.

7. Tribes, geo-heritage and tourism

Rajasthan has twelve notified Scheduled Tribes. The Meena and the Bhil groups are the two largest: the Bhil group (with its sub-tribes) accounts for about 44 per cent of the ST population and the Meena for about 47 per cent in Census 2011. The Sahariya of Baran district are the state's only particularly vulnerable tribal group. The Aravalli and the southern hills are the tribal homeland: Banswara (about 76 per cent ST), Dungarpur (about 71 per cent) and Pratapgarh (about 63 per cent) are the districts where tribes are the majority on the Census 2011 district map.

Geo-heritage is the new Mains angle. The UNESCO Global Geoparks programme recognises a single area of internationally significant geology that is managed for education, conservation and local development together. Rajasthan's potential rests on its ancient rocks and fossils: the Jodhpur Group-Malani Igneous Suite contact at Jodhpur, which the Geological Survey of India has declared a National Geological Monument; the Akal Wood Fossil Park near Jaisalmer, also a National Geological Monument and under the jurisdiction of the Desert National Park; and the Aravalli folds and mineral belts. These sites have the geology; the case for a geopark depends on management and community use, which is the part still to be built.

Tourism geography: how the landscape shapes the circuits
SettingAttractions
DesertJaisalmer, Bikaner, Jodhpur: forts, dunes, camel safaris

Golden TriangleJaipur, with Delhi and Agra
🧠 Setting first, then place
To recall a tourism circuit, name the setting first: desert, lake, wildlife, havelis, pilgrimage. Then attach two or three places to it. This works better than memorising a flat list of towns and avoids moving a place to the wrong circuit.

Key takeaways

  • Soils follow rainfall: sandy desert soils in the west, alluvium in the east, black soil in Hadoti, red and yellow soil in the south; the main problems are wind erosion, canal-command salinity and Chambal ravines.
  • Crops match water and soil: bajra, guar and moth in the arid west, wheat, cotton and mustard under canals, soybean and coriander in Hadoti, maize in the south; Rajasthan leads in bajra, mustard, guar and wool, but shares change yearly.
  • The Indira Gandhi Canal (begun 1958, renamed 1984) brings Sutlej-Beas water from Harike in Punjab to the north-west; wells and tubewells remain the largest source, and tanka, khadin and johad are the traditional answers.
  • Livestock and its science: Rajasthan leads in wool and camels; CAZRI Jodhpur (1959) and the sheep and wool institute at Avikanagar (1962) support the sector.
  • The Aravalli carries zinc-lead, copper and marble; the west has lignite, gypsum, salt and the Barmer oil fields; solar and wind, with Bhadla at 2,245 MW by 2020, define the new power geography.
  • At Census 2011 Rajasthan had 68,548,437 people, a sex ratio of 928, about 66 per cent literacy and 24.9 per cent urban; tribes are 13.48 per cent, concentrated in Banswara and Dungarpur, and geo-heritage and tourism build on the landscape.

Practice questions (16)

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.

  1. Which soil is characteristic of the Hadoti plateau (Kota, Bundi, Baran and Jhalawar)?

    1. Desert (arid) soil
    2. Black soil
    3. Red and yellow soil
    4. Saline-alkaline soil
    Show answer

    Answer: B — Black soil

    Hadoti has black soil that holds moisture and suits soybean, cotton, coriander and oranges. Desert soil belongs to the west, red and yellow soil to the southern hills around Udaipur and Banswara, and saline soil to low basins such as the lower Luni.
  2. From which headworks does the Indira Gandhi Canal draw its water?

    1. Harike barrage at the Sutlej-Beas confluence in Punjab
    2. Rana Pratap Sagar on the Chambal at Rawatbhata
    3. Mahi Bajaj Sagar on the Mahi in Banswara
    4. Bisalpur dam on the Banas in Tonk
    Show answer

    Answer: A — Harike barrage at the Sutlej-Beas confluence in Punjab

    The canal begins at the Harike barrage in Punjab, where the Sutlej and Beas meet, and enters Rajasthan at Hanumangarh. The other three are Rajasthan dams on the Chambal, Mahi and Banas, none of which feeds this canal.
  3. Which mineral is mined at Khetri in Jhunjhunu district?

    1. Zinc
    2. Lignite
    3. Copper
    4. Gypsum
    Show answer

    Answer: C — Copper

    Khetri is the copper-mining town of the Aravalli belt. Zinc comes from Zawar, Rajpura-Dariba and Rampura Agucha, lignite from Bikaner and Barmer, and gypsum from Bikaner, Nagaur and Jaisalmer.
  4. Which Scheduled Tribe, found mainly in Baran district, is the state's particularly vulnerable tribal group?

    1. Bhil
    2. Garasia
    3. Sahariya
    4. Damor
    Show answer

    Answer: C — Sahariya

    The Sahariya of Baran are the only particularly vulnerable tribal group in Rajasthan. Bhil, Garasia and Damor are tribes of the southern Aravalli belt and are not classed this way.
  5. Which one of the following pairings of mineral and place is INCORRECT?

    1. Zinc-lead and Rampura Agucha
    2. Salt and Sambhar
    3. Marble and Makrana
    4. Zinc and Khetri
    Show answer

    Answer: D — Zinc and Khetri

    Khetri is a copper centre, not a zinc one. Rampura Agucha is a zinc-lead mine, Sambhar yields salt and Makrana is the marble town of Nagaur.
  6. Match each breed with its region.
    (i) Tharparkar cattle
    (ii) Chokla sheep
    (iii) Bikaneri camel
    (iv) Nagauri bullock
    w Bikaner x Nagaur y Shekhawati z Jaisalmer-Barmer

    1. (i)-z, (ii)-y, (iii)-w, (iv)-x
    2. (i)-z, (ii)-w, (iii)-y, (iv)-x
    3. (i)-x, (ii)-y, (iii)-w, (iv)-z
    4. (i)-z, (ii)-y, (iii)-x, (iv)-w
    Show answer

    Answer: A — (i)-z, (ii)-y, (iii)-w, (iv)-x

    Tharparkar belongs to the Jaisalmer-Barmer belt, Chokla to Shekhawati, Bikaneri to Bikaner and Nagauri to Nagaur. Swapping the camel and the sheep breeds is the usual error, because Bikaner also has sheep.
  7. Consider the following statements about the Indira Gandhi Canal.
    P. Construction began in 1958 under the name Rajasthan Canal.
    Q. It was renamed on 2 November 1984 after the death of Indira Gandhi.
    R. Its headworks are at Harike, inside Rajasthan.
    S. Its main canal runs through Hanumangarh and Bikaner.
    Which of the statements is/are correct?

    1. P, Q and R only
    2. P and S only
    3. P, Q and S only
    4. Q, R and S only
    Show answer

    Answer: C — P, Q and S only

    P, Q and S are correct. R is wrong because Harike is in Punjab, on the Sutlej and Beas, so every option containing R fails.
  8. Arrange these events of the Indira Gandhi Canal in chronological order, earliest first.
    P. Construction begins as the Rajasthan Canal
    Q. The engineer Kanwar Sain puts forward the idea
    R. The canal is renamed after Indira Gandhi
    S. Stage II is completed

    1. P, Q, R, S
    2. Q, P, S, R
    3. Q, R, P, S
    4. Q, P, R, S
    Show answer

    Answer: D — Q, P, R, S

    The idea came in the late 1940s, construction began in 1958, the canal was renamed in 1984 and Stage II was completed in 2010. Putting the rename after Stage II is the trap, because the renaming happened while Stage I was still being finished.
  9. Bisalpur dam, completed in 1999 and a source of drinking water for Jaipur and Ajmer, stands on which river and in which district?

    1. Luni, in Pali
    2. Banas, in Tonk
    3. Mahi, in Banswara
    4. Chambal, in Kota
    Show answer

    Answer: B — Banas, in Tonk

    Bisalpur is a gravity dam on the Banas near Bisalpur in Tonk district. The Jawai dam is on the Luni tributary in Pali, Mahi Bajaj Sagar is on the Mahi in Banswara, and the Chambal dams are at Rawatbhata and Kota.
  10. Four districts are described using Census 2011 figures. W: density about 17 per sq km, the thinnest of all districts. X: the most populous district, density nearly 600. Y: the highest sex ratio of any district, just under 1,000, and over 70% Scheduled Tribes. Z: about 60% urban. Which identification is correct?

    1. W Barmer, X Jaipur, Y Dungarpur, Z Kota
    2. W Jaisalmer, X Jaipur, Y Banswara, Z Ajmer
    3. W Jaisalmer, X Jaipur, Y Dungarpur, Z Kota
    4. W Jaisalmer, X Jodhpur, Y Dungarpur, Z Kota
    Show answer

    Answer: C — W Jaisalmer, X Jaipur, Y Dungarpur, Z Kota

    Jaisalmer has the lowest density, Jaipur the largest population, Dungarpur the highest sex ratio with a tribal majority, and Kota the highest urban share. Barmer is thin but not the thinnest, Banswara's sex ratio (about 980) is lower than Dungarpur's, Ajmer is less urban than Kota and Jodhpur is not the most populous.
  11. According to Census 2011, what share of Rajasthan's population belonged to the Scheduled Tribes?

    1. About 8.6 per cent
    2. About 13.5 per cent
    3. About 17.8 per cent
    4. About 21.3 per cent
    Show answer

    Answer: B — About 13.5 per cent

    Scheduled Tribes were 9,238,534 persons, 13.48 per cent of the state. The figure of about 17.8 per cent is the Scheduled Caste share, and 21.3 per cent is the 2001-2011 decadal growth of the whole population.
  12. In which pair of districts did Scheduled Tribes form the majority of the population at Census 2011?

    1. Jaisalmer and Barmer
    2. Alwar and Bharatpur
    3. Banswara and Dungarpur
    4. Kota and Bundi
    Show answer

    Answer: C — Banswara and Dungarpur

    Scheduled Tribes were about 76 per cent in Banswara and about 71 per cent in Dungarpur (Pratapgarh, about 63 per cent, is also a majority district but is not among the options). Jaisalmer and Barmer are desert districts with small tribal shares, and Alwar, Bharatpur, Kota and Bundi are plains or plateau districts with few tribal people.
  13. Bhadla Solar Park, reported to have about 2,245 MW of commissioned capacity around 2020, lies in which natural region of Rajasthan?

    1. The Hadoti plateau
    2. The Aravalli hills
    3. The eastern alluvial plains
    4. The Thar desert
    Show answer

    Answer: D — The Thar desert

    Bhadla is in the Thar, where clear skies and open land favour solar generation. Hadoti, the Aravalli and the eastern plains have more rain, cloud or settlement and are not the setting for such a park.
  14. Consider the following statements.
    P. Rampura Agucha in Bhilwara is a zinc-lead mine.
    Q. Zawar in Udaipur is a zinc-mining centre.
    R. Sambhar is a source of salt.
    S. Khetri in Rajsamand is the main zinc town.
    Which of the statements is/are correct?

    1. P, Q and R only
    2. P and S only
    3. Q, R and S only
    4. P, Q, R and S
    Show answer

    Answer: A — P, Q and R only

    P, Q and R are correct. S is wrong twice over: Khetri lies in Jhunjhunu district and is a copper centre. Rajsamand's mining name is Rajpura-Dariba.
  15. Which of the following is a site that the Geological Survey of India has declared a National Geological Monument in Rajasthan?

    1. The Jodhpur Group-Malani Igneous Suite contact at Jodhpur
    2. Sambhar salt lake, in Jaipur, Nagaur and Ajmer districts
    3. Keoladeo wetland and waterfowl habitat, Bharatpur
    4. Ranthambore tiger reserve in Sawai Madhopur district
    Show answer

    Answer: A — The Jodhpur Group-Malani Igneous Suite contact at Jodhpur

    The Jodhpur Group-Malani Igneous Suite contact at Jodhpur was notified as a National Geological Monument by the Geological Survey of India. Sambhar and Keoladeo are Ramsar wetlands, and Ranthambore is a wildlife area, none a geological monument.
  16. Which traditional structure of Bikaner, Jodhpur and Jaisalmer is a covered underground tank that stores rain-water collected from a prepared catchment?

    1. Khadin
    2. Johad
    3. Jhalara
    4. Tanka
    Show answer

    Answer: D — Tanka

    The tanka is a covered underground tank for rain-water. The khadin is an embanked farm, the johad an earthen check-dam of Alwar, and the jhalara a stepwell for towns and temples.
