As in the other high-altitude regions of the country, the yak is a significant contributor to the traditional economy.

Alongside Buddhist practices, the Haaps also continue their old shamanistic traditions, the most notable of which is the annual ceremony to honour the guardian deity of the valley, Ap Chhundu. The rituals include the sacrifice of a yak to Ap Chhundu in return for his favors over the valley, which include the deflection of all misfortunes in the valley for a full year, until the next ceremony.
