Selected occupations include agriculturists, herders, pastoralists, etc. Legitimate cowmen were referred to as cattle herders or ranchers. The land they cultivated reduced the area available to nomadic herders, causing disputes over land. They included butchers, cattle herders, shepherds and dairy farmers. The Paleoasian indigenous peoples are hunters, fishermen, and reindeer herders. They were great livestock herders, farmers and made irrigation ditches. They were metalworkers, cultivators of millet, and cattle herders. Conflict between livestock herders and cheetahs is also threatening the population outside protected areas. The inland Chukchi were partial reindeer herders. It is populated only by Bedouin herders of camels. The Even herders also rode their reindeer. Currently, the conflict between Fulani herders and other Nigerian farmers have intensified.
