With reference to subsistence agriculture, consider the following statements: 1. Shifting cultivation is widely practiced in tropical regions using primitive tools. 2. In intensive subsistence agriculture dominated by wet paddy cultivation, per labour productivity is high, but yield per unit area is low. 3. Intensive subsistence agriculture dominated by crops other than paddy is prevalent in regions where geographical conditions do not favour rice cultivation. Which of the statements given above is/are correct? |ForumIAS

[A] 1 and 2 only

[B] 1 and 3 only

[C] 2 and 3 only

[D] 1, 2 and 3

Answer: B

Notes:

Explanation:

Shifting cultivation or slash-and-burn is practiced in tropical regions using primitive tools like sticks and hoes, and land is cleared using fire.
Per labour productivity is low, although yield per unit area is high in wet paddy-dominated intensive subsistence agriculture.
In regions where relief, climate, and soil conditions are not suitable for paddy (like northern China, Manchuria, and western India), crops like wheat, soyabean, and millets are cultivated under similar intensive subsistence practices.
