The Masai who move from place to place

They move their herds from one place to another, so that the grass has a chance to grow again; traditionally, this is made possible by a communal land tenure system in which everyone in an area shares access to water and pasture. Nowadays Maasai have increasingly been forced to settle, and many take jobs in towns.
