The correct answer is a) Wayanad.
Shifting cultivation is a traditional agricultural system in which farmers clear a piece of land by cutting and burning the vegetation, then cultivate it for a few years before moving on to another plot. This type of agriculture is often practiced in areas with low population density and abundant forest resources.
Wayanad is a district in the state of Kerala, India. It is home to a number of tribal groups who practice shifting cultivation. The practice is known as “podu” in Wayanad.
Podu is a sustainable form of agriculture when practiced in a traditional way. However, it can become unsustainable when the land is cleared too often or when the population density increases. In Wayanad, podu is currently under threat from deforestation and development.
Palakkad, Kozhikode, and Kannur are also districts in Kerala, but they do not have as many tribal people as Wayanad. As a result, shifting cultivation is not as common in these districts.
In conclusion, the correct answer to the question “Shifting cultivation is still practiced in some tribal areas of: a) Wayanad b) Palakkad c) Kozhikode d) Kannur” is a) Wayanad.
