Why is seasonal movement of pastoralists evidence of local ecological knowledge?

Correct answer: They understood seasons grass water and animal behaviour

Seasonal movement shows that pastoralists observed and understood their environment. They needed to know when rains arrived, where grass would grow, which water sources were available and how animals reacted to weather and terrain. This knowledge helped them choose safe and productive routes. It was usually developed through long experience and passed between generations, allowing communities to adapt their livelihood to changing ecological conditions.

Option A is correct because it names the environmental information needed for successful movement. Random travel would risk losing animals and finding no water or fodder. Pastoralists did not depend only on government orders or on no experience; their decisions came from observation, memory and community knowledge. Thus seasonal mobility was a skilled practice based on local ecological understanding, not aimless wandering.
