Why can seasonal mobility of pastoralists be called evidence of local ecological knowledge?

Correct answer: They understood seasons grass water and livestock behaviour

Seasonal movement shows that pastoralists observed their surroundings and made decisions from accumulated experience. They knew when particular areas would receive rain, where grass would remain available, which routes had water, and how animals behaved in different conditions. This knowledge helped them protect livestock and use resources without staying in one place all year. It was usually learned within families and communities and adjusted to local conditions.

Option A is correct because it connects movement with knowledge of seasons, grass, water, and livestock behaviour. Random movement would not reliably support animals, especially when water and pasture are limited. Government orders alone also cannot explain the detailed timing and route choices of pastoral groups. Their mobility was therefore not evidence of ignorance; it was an adaptive strategy based on local ecological knowledge developed through repeated observation and experience.
