The transhumance and the nomadic ranching may seem very similar, but they are not and they have one very big important difference between them. The transhumance ranching is the type of ranching where the ranchers are moving their livestock seasonally. That usually happens twice a year. The movement occurs when the season change. It is driven by the climate, and it can be when there's wet and dry season, or warm and cold season, and the movement can be vertical, from the mountains toward the lowlands and vice versa, or horizontal, toward places with more suitable weather conditions at that period. The The nomadic ranching, on the other side, is a type of ranching where the livestock is moved constantly, almost on a daily or weekly basis. This type of ranching is driven by the amount of food sources at a particular place. The nomads keep their livestock at a particular spot depending on how much food there is available, which usually is in low amount, so they are in constant movement for new grazing lands.
