A fact is a pragmatic truth, a statement that can, at least in theory, be checked and confirmed. Facts are often contrasted with opinions and beliefs, statements which are held to be true, but are not amenable to pragmatic confirmation.The word fact derives from the Latin Factum, and was first used in English with the same meaning: "a thing done or performed", a use that is now obsolete. The common usage of, "something that has really occurred or is the case", dates from the middle of the sixteenth century. Fact is sometimes used as synonymous with truth or reality, as distinguishable from conclusions or opinions. This use is found in such phrases Matter of fact, and "... not history, nor fact, but imagination."
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.
