(iii) What is shifting cultivation? What are its disadvantages?
Answer: Shifting cultivation or slash-and-burn cultivation is a type of farming activity which involves clearing a plot of land by felling trees, burning the felled trees, mixing the ashes with soil, and then growing crops like maize, yam, potatoes and cassava on the cleared land. After the soil loses its fertility, the land is abandoned and the cultivator moves on to a new plot.

- Insufficient cultivation of crops for a large population.

The product can be processed on the farm itself or in nearby factories. The development of a transport network is thus essential for such farming. This type of farming can be found in tropical regions of the world like India, Sri Lanka and Brazil.

Hence, in India, agriculture is a primary activity.
(ii) Different crops are grown in different regions.
Answer: The type of crop grown is dependent upon the type of soil and the type of climate of a region.

The demand for produce, labour and level of technology are some other factors that decide the type of crops grown in a particular region.
