are used for grazing and farming
Answers
Answer:
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed to consume wild vegetations outdoor in order to convert grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming.

Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing deliberately uses grazing animals to improve the biodiversity of a site.
Grazing has existed since the birth of agriculture; sheep and goats were domesticated by nomads before the first permanent settlements were created around 7000 BC, enabling cattle and pigs to be kept.
Grazing's ecological effects can be positive and include redistributing nutrients, keeping grasslands open or favouring a particular species over another. There can also be negative effects to the environment with overgrazing, such as soil degradation, ecological disturbance and desertification.
