The Maasai Mara is Kenya's most famous reserve, the site of the wildebeest migration, and the economic engine of Kenya's tourism industry. It was carved from Maasai grazing land in 1961, and the Maasai have been negotiating their relationship with it ever since. Revenue sharing is contentious, land rights are disputed, and the pressure from tourism is relentless. The Mara is beautiful, profitable, and contested. Who benefits, who loses, and whether the current model is sustainable are questions Kenya has not resolved.
