Wai Humba Festival

The Wai Humba Festival is a community-driven movement that emphasizes the protection of Sumba’s water sources and environmental heritage. Held annually in October or November, the festival brings together youth and elders from different tribes to perform rituals at sacred water springs. The event includes traditional dances, music, and discussions on sustainable living, all rooted in Marapu ecological wisdom. It is a powerful example of how ancient beliefs are being used to address modern environmental challenges.
