Prerequisites

The Hook: Three Farmers, One State

Connect

A farmer near Arang in the plain transplants paddy in bunded Kanhar fields and hopes the Mahanadi canal will water a gram crop in winter. A farmer near Kondagaon in Bastar sows maize and kodo on a red, gravelly upland at the forest edge. A farmer near Ambikapur in the north grows paddy and niger, and worries about frost in January. All three live in Chhattisgarh, but they farm in three different worlds.

How does agricultural science divide the state, and why does the division matter for policy?

Why it matters: Prelims asks the number and names of the zones, the wettest zone and zone-wise crops. Mains GS-III asks for region-specific strategies: a single “paddy policy” does not fit all three zones.


What Is an Agro-Climatic Zone?

An agro-climatic zone (कृषि-जलवायु क्षेत्र) is a land unit with broadly uniform climate (especially rainfall and temperature), soils, terrain and cropping potential, so that one package of crops and practices suits it.

LevelSchemeChhattisgarh’s place

StateNational Agricultural Research Project (NARP) zones, used by IGKV Raipur3 zones: Chhattisgarh Plains, Bastar Plateau, Northern Hills

The research and extension body for these zones is Indira Gandhi Krishi Vishwavidyalaya (इंदिरा गांधी कृषि विश्वविद्यालय), Raipur, the state agricultural university (established 1987), with a zonal research station in each zone.

Rainfall figures differ by study
Studies based on different periods give different zone averages, roughly in the 1,100–1,500 mm range. One IMD-based study gives about 1,200 mm for the Plains and about 1,490 mm for Bastar; another gives about 1,100, 1,270 and 1,345 mm for the Plains, Northern Hills and Bastar. The order is the same in every study: Bastar wettest, Plains driest. Learn the order, not a single number.
Rain-fed almost everywhere
Per a NABARD assessment, about 74% of the cropped area in the Plains, 97% in the Bastar Plateau and 95% in the Northern Hills is rain-fed. Even the most irrigated zone depends mainly on the monsoon.

Zone-Wise Issues and Strategies (Mains material)

ZoneKey problemsStrategy
PlainsPaddy mono-cropping; dry western plain (Maikal rain shadow: Kabirdham, Bemetara); under-used rabi; soil fatigueDiversify rabi to gram, lathyrus, linseed through utera; efficient canal use; soybean–gram rotations; protective irrigation for the western plain
Bastar PlateauPoor, eroded upland soils; almost no irrigation; low input use; remoteness and insecurity in Left-Wing Extremism-affected districtsMillets (kodo-kutki, ragi) with processing and MSP; maize; watershed works and small tanks; forest-produce value chains; organic branding
Northern HillsShort growing season, frost and cold; hilly terrain; low irrigationMaize, niger, mustard and pulses; horticulture on slopes; soil and water conservation; solar pumps
Why zones matter for policy
A uniform incentive such as a high paddy price helps the irrigated plain most. Upland farmers in Bastar and Surguja, who grow little surplus paddy, gain less. Zone-specific incentives (millets in Bastar, maize and pulses in the north, rabi diversification in the plain) spread benefits more evenly. This is a strong Mains argument.

Memory Tricks

P-B-N: Plain is Poor in rain, Bastar Brims
Rainfall order: Bastar > Northern Hills > Plains. “Bastar Brims, the Plain is Poor in rain.”
Zones = Divisions, roughly
Surguja division → Northern Hills; Bastar division → Bastar Plateau; Raipur, Durg and Bilaspur divisions → Plains. Three zones, five divisions.

Common Mistakes

Trap 1: Four zones
Some state-GK books describe four physiographic divisions. The agro-climatic division is three zones. Do not mix the two schemes.
Trap 2: The plain is the wettest
The plain is the rice bowl, but it is the driest of the three zones. It grows the most paddy because of soils, flat land and canal irrigation, not because of the highest rainfall.
Trap 3: Central Plateau region
At the national level Chhattisgarh is in the Eastern Plateau and Hills region (VII), with Jharkhand and parts of Odisha, West Bengal and Maharashtra. “Central Plateau and Hills” is a trap option.

Practice

These are original practice questions in CGPSC style, not previous-year questions.

Level 1: Foundation

  1. Chhattisgarh is divided into ________ agro-climatic zones.
  2. The agro-climatic zone with the highest average rainfall is the ________.
  3. In the Planning Commission’s scheme, Chhattisgarh falls in the ________ region.
Answers
  1. Three (Chhattisgarh Plains, Bastar Plateau, Northern Hills)
  2. Bastar Plateau
  3. Eastern Plateau and Hills (Region VII)

Level 2: Prelims MCQs

Q1. Consider the following statements about the agro-climatic zones of Chhattisgarh:

  1. The Chhattisgarh Plains zone receives the highest average rainfall in the state.
  2. The Chhattisgarh Plains zone has the largest share of irrigated area.
  3. Kodo, kutki and ragi are important crops of the Bastar Plateau zone.

Which of the statements given above is/are correct?

(a) 1 and 2 only (b) 2 and 3 only (c) 3 only (d) 1, 2 and 3

Answer and explanation
(b) 2 and 3 only. The Plains are the driest zone, so statement 1 is wrong; Bastar is the wettest. The Plains have the main canal commands (Mahanadi, Tandula, Hasdeo), so they are the most irrigated. Millets such as kodo, kutki and ragi are typical of the Bastar uplands.

Q2. Match List-I (Agro-climatic zone) with List-II (Zonal research station of IGKV):

List-IList-II
A. Chhattisgarh Plains1. Ambikapur
B. Bastar Plateau2. Raipur
C. Northern Hills3. Jagdalpur

(a) A-2, B-3, C-1 (b) A-3, B-2, C-1 (c) A-2, B-1, C-3 (d) A-1, B-3, C-2

Answer and explanation
(a) A-2, B-3, C-1. Each zone has a zonal research station: Raipur for the Plains, Jagdalpur for Bastar and Ambikapur for the Northern Hills.

Q3. In the Planning Commission’s division of India into 15 agro-climatic regions, Chhattisgarh falls in the:

(a) Central Plateau and Hills Region (b) Eastern Plateau and Hills Region (c) Lower Gangetic Plains Region (d) Southern Plateau and Hills Region

Answer and explanation
(b) Eastern Plateau and Hills Region (Region VII). Most of Madhya Pradesh falls in the Central Plateau and Hills Region, which is the trap option.

Q4. Which of the following districts lies in the Northern Hills agro-climatic zone of Chhattisgarh?

(a) Kondagaon (b) Bemetara (c) Jashpur (d) Mahasamund

Answer and explanation
(c) Jashpur. Jashpur is in Surguja division, which forms the Northern Hills zone. Kondagaon is in the Bastar Plateau; Bemetara and Mahasamund are in the Plains.

Level 3: Mains Answer Writing

Q1. Name the agro-climatic zones of Chhattisgarh and state one distinguishing feature of each. (60 words)

Model answer outline
  • Chhattisgarh Plains: central basin; lowest rainfall but the most irrigation; Kanhar–Dorsa–Matasi–Bhata soils; paddy with rabi gram and lathyrus.
  • Bastar Plateau: highest rainfall; red and laterite uplands; maize, kodo-kutki, ragi, niger; about 97% rain-fed.
  • Northern Hills: Surguja division; red-yellow soils, cold winters; paddy, maize, niger, mustard.

Q2. “One agricultural policy cannot suit all of Chhattisgarh.” Examine this statement with reference to the state’s agro-climatic zones. (150–200 words)

Model answer outline

Intro: IGKV divides Chhattisgarh into three agro-climatic zones that differ in rainfall, soil, terrain and irrigation.

Differences:

  1. Plains: driest zone yet the most irrigated; deep Kanhar soils; paddy surplus and procurement-driven farming.
  2. Bastar Plateau: wettest, but thin red-laterite uplands and about 97% rain-fed; millets and forest produce matter more than surplus paddy.
  3. Northern Hills: cold winters, slopes and about 95% rain-fed; maize, niger and pulses.

Why uniform policy fails: a high paddy price mainly rewards plains farmers with surplus; uplands need water harvesting, millet markets and soil conservation instead.

Zone-specific approach:

  • Plains: rabi diversification via utera, water-use efficiency, soybean–gram rotations.
  • Bastar: Millet Mission, processing units, watershed works, organic and tribal branding.
  • North: maize and pulses, horticulture, solar pumps.

Conclusion: Region-specific packages, guided by IGKV’s zonal stations, give more equitable and climate-resilient growth.

Key Takeaways

Key Takeaways
  1. Chhattisgarh has three agro-climatic zones matching its three relief units: Plains, Bastar Plateau, Northern Hills.
  2. Bastar is the wettest, the Plains the driest, yet the Plains are the most irrigated and grow the most paddy.
  3. Nationally the state lies in the Eastern Plateau and Hills Region (VII).
  4. Almost all farming outside the canal commands is rain-fed.
  5. Policy should be zone-specific: rabi diversification in the plain, millets in Bastar, maize and pulses in the north.
