UPSC IAS – 2013
The correct answer is B) Central Asian Steppe.
The description perfectly fits the geographical and cultural characteristics of the Central Asian Steppe. This region experiences a continental climate with extreme temperature variations between summer and winter. Rainfall is typically scanty, classifying it as a semi-arid grassland. Historically, the people of this region were largely nomadic herders due to the vast grasslands suitable for grazing livestock and the need to move in search of pasture.
African Savannah has distinct wet and dry seasons with moderate to high rainfall. North American Prairie has a temperate climate with more consistent rainfall allowing for extensive agriculture in many parts. Siberian Tundra has an arctic climate, permafrost, and low-growing vegetation, not typically supporting large-scale nomadic herding in the manner described.
