Sugar and Cotton Textile Industries, and Key and Footloose Industries (ISC Class 12 Geography)
Updated 18 October 2026 · Fact-checked
Sugar mills sit near cane fields because cane is bulky, weight-losing and perishable; Maharashtra's cooperative mills and tropical yields have drawn the industry south from Uttar Pradesh. Cotton is a pure raw material, so textile mills grew in Mumbai, Ahmedabad and Surat for ports, capital and markets; Mumbai's mills have declined. Key industries supply other industries; footloose industries can locate almost anywhere.
Heavy, perishable cane (100 t) goes only a short way to the mill, but the finished sugar (10 t) can travel far to the market.

Understand Sugar and Cotton Textile Industries, and Key and Footloose Industries
1. Sugar: why near cane. Sugarcane is bulky, weight-losing (only about 10 per cent becomes sugar) and perishable (sucrose falls within about 24 hours of cutting), so mills must be close to the fields; the finished sugar is easy to move.
*Uttar Pradesh (Muzaffarnagar, Saharanpur)*: fertile alluvial soil of the Ganga-Yamuna doab and tarai; canal and tubewell irrigation; large cane area; cheap labour; large northern market; the traditional centre. Problems: lower sucrose and a shorter crushing season because of cold winters; older, smaller mills.
*Maharashtra (Ahmednagar, Pune)*: black soil and irrigation; tropical climate giving higher sucrose and yield per hectare and a longer crushing season; cooperative factories (the first cooperative sugar factory in Asia at Pravaranagar, Ahmednagar district, in 1950); modern larger mills; by-products (ethanol, power from bagasse).
*Present status*: Uttar Pradesh and Maharashtra are the leading states, alternating at the top; the industry has shifted southwards (Maharashtra, Karnataka, Tamil Nadu). By-products: bagasse (fuel, paper), molasses (alcohol, ethanol for blending with petrol), press mud (manure).
2. Cotton textiles. Cotton is a pure, non-weight-losing raw material, so mills can locate near markets, labour and ports as well as near cotton fields.
- *Mumbai*: first successful mill (1854); natural port for importing machinery and exporting cloth; cotton from the black-soil hinterland; humid climate (less thread breakage); capital and enterprise; hydel power; cheap labour; a huge market. Most old mills have closed (high land costs, old machinery, strikes, powerloom competition); the industry moved elsewhere and to garments.
- *Pune*: cotton from the Deccan; skilled labour; road and rail links; nearness to Mumbai.
- *Ahmedabad* ('Manchester of India'): Gujarat's black-soil cotton; cheap labour; local entrepreneurs and capital; humid climate; nearness to Mumbai's market and Kandla port; local thermal power and gas.
- *Surat*: synthetic and cotton textiles, powerlooms, zari work; port (Hazira), gas, entrepreneurial communities; also diamond cutting.
- *Present status*: a shift from large composite mills to decentralised powerloom and handloom sectors and garment exports; Gujarat and Tamil Nadu (Coimbatore, Tiruppur) have grown while Mumbai declined.
3. Key and footloose industries
| Basis | Key (basic) industry | Footloose industry |
|---|---|---|
| Meaning | Products used as inputs by many other industries | Not tied to raw materials or power |
| Examples | Iron and steel, power, cement, petroleum, heavy engineering, chemicals | Electronics, software, gems and jewellery, watches, garments |
| Raw materials | Bulky | Light, high value |
| Location | Near raw materials or ports | Flexible, near skilled labour and markets |
| Scale | Large, capital-intensive | Often smaller |
4. Industrial clusters. A geographical concentration of interlinked firms in the same or related industries that share suppliers, infrastructure, skills and services: the automobile cluster around Chennai, the knitwear cluster of Tiruppur, the diamond cluster of Surat, the IT cluster of Bengaluru. Indices used to identify clusters: number of industrial units, number of industrial workers, power used for industry, total industrial output and value added by manufacturing.
5. A recovery sum (imaginary). Cane of 100 tonnes yields about 10 per cent sugar = 10 tonnes. If delay in crushing cuts recovery to 8 per cent, sugar = 8 tonnes, a loss of 2 tonnes, i.e. 2 / 10 x 100 = 20% of the sugar.

Sugar and Cotton Textile Industries, and Key and Footloose Industries in real life
The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.
Perishable raw material
Suppose a cooperative sugar mill pays farmers to deliver cane within 24 hours of harvest and opens its gates night and day in the crushing season.
Why does it insist on this?
Try it first, then show the solutionSolution
- Cane loses sucrose soon after cutting.
- Speed keeps recovery high.
Answer: Cane is perishable; delay reduces sucrose and sugar recovery.

Example 2: Sugar near cane · 2 marks · Short answerBoard level
Why are sugar mills located near sugarcane fields?
Try it first, then show the solutionSolution
- Cane is bulky and weight-losing, as only about 10 per cent becomes sugar, so carrying it far is costly.
- It is perishable: sucrose falls within about 24 hours of cutting.
Answer: Cane is bulky, weight-losing and perishable.
Example 3: Recovery loss · 4 marks · Short answerHarder board level
A mill crushes 5,000 tonnes of cane at a recovery of 10 per cent but, after delays, only 8 per cent. Calculate sugar in both cases, the loss and the loss as a percentage of the expected sugar, and name the reason for such loss.
Try it first, then show the solutionSolution
- At 10 per cent: 5,000 x 10/100 = 500 tonnes.
- At 8 per cent: 5,000 x 8/100 = 400 tonnes.
- Loss = 100 tonnes, i.e. 100 / 500 x 100 = 20%.
- Reason: cane is perishable and loses sucrose after cutting.
Answer: 500 and 400 tonnes; loss 100 tonnes (20%); perishable cane.

- Present shift: from large composite mills to decentralised powerloom and handloom sectors and garment exports.
Answer: Port, cotton, capital and market made Mumbai first; costs and competition closed mills; Ahmedabad, Surat and Tamil Nadu grew.
Where students lose marks in Sugar and Cotton Textile Industries, and Key and Footloose Industries
The slips examiners see most often, and what to write instead.
Mistake: Giving only one reason for the sugar shift
Four marks need four reasons.
Wrong working
Climate is better in the south.
Right working
Climate, yield and sucrose, season length and cooperative mills.
Do this: Four distinct reasons.
Usually costs: 2 marks.
Mistake: Saying Mumbai's mills still dominate
Most old mills closed.
Wrong working
Mumbai remains the largest cotton centre.
Right working
Most of Mumbai's old mills have closed; industry moved to Gujarat and Tamil Nadu and to garments.

Q3 · 2 marks · Short answerHarder board level
Why are cotton mills not as strictly tied to cotton fields as sugar mills are to cane fields?
Hint
Pure raw material.
Answer
Cotton is a pure, non-weight-losing and non-perishable raw material, so it can be carried to mills near markets, labour and ports.
Q4 · 4 marks · Short answerHarder board level
In a district, sugar mills crush 60,000 tonnes of cane at 11 per cent recovery. After modernisation, recovery rises to 12 per cent for the same cane. Calculate the extra sugar and its percentage increase.
Hint
Compare two outputs.
Answer
Before: 60,000 x 11/100 = 6,600 tonnes. After: 60,000 x 12/100 = 7,200 tonnes. Extra = 600 tonnes; 600 / 6,600 x 100 = 9.1% increase.
Q5 · 4 marks · Short answerHOTS / competency
A student claims the sugar industry should return to Uttar Pradesh because cane grows there on fertile soil. Evaluate with reference to climate and mills.
Hint
Recovery and season.
Answer
Uttar Pradesh does have fertile alluvial soil, irrigation and a big market, but cold winters give lower sucrose and a shorter crushing season, and many mills are old and small with lower recovery. Maharashtra and the south offer higher yield, a longer season and modern cooperative mills, so the shift south is economic; modernising northern mills could improve their position.
