Solution
The correct option is C 1 and 2 only
Explanation:
Statement 1 is correct: Primitive subsistence agriculture or shifting cultivation is widely practiced by many tribes in the tropics, especially in Africa, south and central America, and Southeast Asia. The vegetation is usually cleared by fire, and the ashes add to the fertility of the soil. Shifting cultivation is thus also called slash and burn agriculture. The cultivated patches are very small and cultivation is done with very primitive tools such as sticks and hoes
Statement 2 is correct: After some time (3 to 5 years) the soil loses its fertility. Once the land becomes inadequate for crop production, it is left to be reclaimed by natural vegetation, and the farmer shifts to other parts and clears another patch of the forest for cultivation.
Statement 3 is incorrect: These systems are naturally suited for harsh environments
