Explanation:

Transhumance is a type of nomadism or pastoralism, a seasonal movement of people with their livestock between fixed summer and winter pastures. In montane regions (vertical transhumance), it implies movement between higher pastures in summer and lower valleys in winter. Transhumance is also practiced horizontally i.e. between latitudes.

Subsistence agriculture is associated with a settled way of life and cannot be related to Transhumance
