Among early peoples, a cause of migration was following herds for hunting. what would be a reason for settlement?

People settled as a result of sedentary agriculture. Sedentary farming is a method of agriculture in which the same land is farmed every year. This is in contrast to nomadic farming, in which new areas are farmed as the soil becomes less nutrient-rich from extensive planting, and shifting cultivation, which uses controlled forest fires to produce arable land.
