“Adumu” is the dance traditionally performed by the Maasai in which warriors enter a circle and repeatedly jump high into the air. The higher the warrior elevates, the more glory he receives and the more pleasure the community takes. We chose “Adumu” as an emblem of Maasai at the height of our cultural glory and of elevating out of poverty and land rights abuses linked to irresponsible tourism and the aftermath of colonialism. We are elevating opportunities for those left behind, building awareness around the crisis of irresponsible tourism and Indigenous land rights, and driving a scalable and replicable solution.

Nelson Ole Reiya 

Nelson Reiya is the founder of Nashulai, the first Maasai-owned Conservancy in the Maasai Mara that shares Adumu’s vision of conservation that integrates people and wildlife together in the same ecosystem. Nashulai is located in a key part of Kenya; it is a 5000 acre triangle of land abutting the Mara National Reserve on one side and two other large conservancies on the others. Thus, Nashulai is a critical migratory corridor of the Maasai Mara ecosystem. Growing up on the land, Nelson saw the combined pressures of climate change, habitat depletion, external development, land commodification, and poverty increasingly imperil the area’s capacity to sustain life-human, pastoral, and wild. Land was being fenced and sold off at an alarming rate. With Nelson’s leadership, the landowning families of Nashulai came together to form the conservancy to regenerate the habitat.

Children need education and equality to thrive. It is a guiding principle for Nashulai. And the way our community has rallied on behalf of our beloved children is nothing short of amazing.” Nashulai has advanced opportunities for all children -- including initiatives to reduce infant mortality, eliminate female circumcision and early marriage; create equal opportunity for access to education; and build local youth capacity and leadership. They have built two new schools within Nashulai as well as provided scholarships for 62 boys and girls from the community to attend secondary school and university.
