Why can pastoral mobility in Africa be considered a form of environmental knowledge?

Correct answer: Pastoralists chose routes according to fodder, water, season and drought

The direct answer is Option A: pastoralists chose routes according to fodder, water, season and drought. Mobility was not random wandering. Pastoralists observed rainfall, grass growth, water sources, animal health and seasonal changes. They moved herds to places where animals could feed and survive, while avoiding areas affected by drought or scarcity. The fact chain is: environmental observation → route selection → better access to resources → protection of animals and livelihood. Option A is correct because movement shows practical knowledge of the environment and a planned survival strategy. Option B is wrong because movement had clear economic and ecological reasons. Option C is wrong because knowing water sources was essential. Option D is wrong because cattle, their food and water needs directly determined routes. Memory cue: pastoral mobility means “knowledge in motion.”
