The correct option is Primitive subsistence agriculture.
Explanation
Slash-and-burn agriculture, technically known as shifting cultivation, is a farming practice where a patch of forest land is cleared by cutting and burning vegetation. The ash produced provides nutrients (potash) to the soil. This method is characterized by the use of primitive tools (such as hoes and digging sticks), reliance on the natural fertility of the soil, and dependence on monsoon rains rather than irrigation.
This practice is classified as Primitive Subsistence Agriculture because:
- Subsistence Nature: The produce is primarily for the consumption of the farmer's family, with little surplus for trade.
- Low Technology: It does not utilize modern inputs like chemical fertilizers, high-yielding variety seeds, or machinery.
- Land Rotation: When soil fertility decreases, farmers shift to a new patch of land, allowing the previous patch to regenerate naturally (fallow period).
In contrast:
- Plantation Agriculture is a commercial system growing a single crop (e.g., tea, coffee) on large estates using capital-intensive methods.
- Extensive Grain Agriculture involves highly mechanized commercial farming on large plots, typical of mid-latitude grasslands.
- Market Gardening focuses on the intensive cultivation of high-value crops (fruits, vegetables) for urban markets.
Key Takeaway
Slash-and-burn is a form of primitive subsistence agriculture widely known by local names such as Jhumming in North-East India, Milpa in Mexico, and Roca in Brazil.
