[Globetrotter] In Mwanza, Tanzania, Nairukoki Leyian-Naisinyai tells me that here, "Corporations come with papers from the government claiming that they have the right to our land." She points to the large corporations that have entered the lands of the Maasai people to mine rubies and tanzanite. The Maasai can neither assert their rights to the land nor benefit from the mining of these precious resources.
