The correct option is (b).
Explanation
Intensive Subsistence Agriculture is the most prevalent form of farming in the densely populated regions of monsoon Asia (South, Southeast, and East Asia). It is driven by the necessity to produce maximum food from limited land resources.- Statement 1 is Incorrect: This system is characterized by very small landholdings due to high population pressure and right of inheritance. Farmers cultivate these small plots using simple tools and abundant family labor. The use of large plots and complex machinery is a feature of Extensive Commercial Grain Farming.
- Statement 2 is Correct: Rice is the principal crop in intensive subsistence agriculture dominated by wet paddy cultivation. It is the staple food for the vast majority of the population in these regions.
- Statement 3 is Incorrect: The tropical and sub-tropical climatic conditions, characterized by warm temperatures and sufficient rainfall, along with fertile soil, allow for intensive land utilization. Consequently, farmers are often able to raise two or three crops annually from the same plot, rather than just one.
Key Takeaway: Intensive Subsistence Agriculture is defined by high labor intensity, small land size, and multiple cropping patterns, contrasting sharply with the mechanization and monoculture of commercial farming.
