Waik Nasi-yohn Jehngitha ab Amjed g So-nohla Tohono/Simposio Tri-nacional del Desierto Sonorense

Organized by representatives from the Tohono O’odham Nation, Mexico and the United States, this biennial symposium offers presentations and dialogue about the dynamics of natural and cultural ecology, environmental challenges, and their relationships to peoples–past and present–living in the Sonoran Desert.

The Tri-National Sonoran Desert Symposium was established to promote increased understanding, conservation and celebration of the natural and cultural resources of the Sonoran Desert, and to foster communication and productive collaboration dedicated to this purpose.
