Explain the agricultural importance of the area marked as B.
Explain the agricultural importance of the area marked as B.
Official answer
Region B, the Prairies of North America (Canada and USA), is agriculturally important as the world's leading zone of mechanised wheat and maize production.
Key importance
- Very large, single-crop farms worked by very few labourers using combine harvesters and modern machinery.
- High yield per farmer, making the region a major global exporter of wheat, often called the 'granary of the world'.
Marking scheme
- 1.1 mark for explaining that region B (Prairies of North America) is a leading mechanised producer and exporter of wheat/maize — the 'granary of the world'.
Hint
Think of the North American grassland belt famous for large mechanised wheat and maize farms and global grain exports.
Quick oral answer
Region B, the North American Prairies, is agriculturally important as a highly mechanised, large-scale wheat and maize belt that is a major global grain exporter.
Common mistakes
- 1.Naming only the crop without explaining its agricultural/economic importance.
- 2.Confusing the Prairies with the Pampas of Argentina or the Steppes of Eurasia.
- 3.Omitting the key feature of mechanisation and large farm size, which is central to 'extensive' farming.
Analysis and explanation
This question requires linking region B to its known agricultural significance.
Concept
- The Prairies of North America are flat, fertile grasslands in the mid-latitude interior of Canada and the USA.
- Farming here is capital-intensive rather than labour-intensive: enormous mechanised farms, extensive use of combine harvesters, silos, and rail transport to ports.
Why B matters
- The scale of production and export makes the Prairies one of the most important wheat-and-maize-producing belts on Earth, feeding both domestic markets and global grain trade.
Exam tip: For 'agricultural importance' questions, always mention scale of production, degree of mechanisation, and export significance — one-line answers that name only the crop lose marks.
Interesting facts
A single Prairie wheat farm can extend to over 500 hectares, worked by only a handful of people using modern combine harvesters.
Canada and the USA together are among the top wheat exporters in the world, a direct result of Prairie grain farming.
The term 'granary of the world' has historically been applied to the Prairies because of their massive surplus wheat production for export.

Frequently asked questions
Why are the Prairies called the 'granary of the world'?
Because their vast, highly mechanised farms produce a huge surplus of wheat and maize that is exported globally, historically making the region one of the world's most important grain-supplying areas.
How is extensive commercial grain farming different from intensive farming?
Extensive farming uses very large farms with low labour input and high mechanisation to maximise output per worker, whereas intensive farming uses small plots with high labour input to maximise output per unit of land.
