We work in Kenya’s South Rift Valley, a bridge between the Maasai Mara and Amboseli. In this area, local Maasai communities have lived with their livestock alongside wildlife, forests, and grasslands, maintaining a landscape of exceptional biological and cultural diversity. This rangeland hosts one of the richest large mammal populations on earth, including both wildlife and livestock. This co-existence is enabled primarily by the communal and semi-nomadic form of local land use, which encourages mobility to ensure survival. Today, this is an increasingly threatened landscape, confronting a growing population, a culture in transition, and land use changes that threaten both wildlife and their livestock.
