Polyandry as a social institution has often been connoted as a cultura
l oddity or an ethnographic fossil in the evolution of family. In part
, this view has resulted from a fragmented or isolated analytical fram
e work. This article, in contrast, takes a more holistic point of View
to express the institution in its ecological, economic-and cultural p
erspectives through a study of the Jaunsaries, a Central Himalayan com
munity of India. The Jaunsaries have undergone a number of classificat
ion and development changes. At present, the Jaunsaries are a schedule
d tribe, and have been so since the Jaunsari-Bawar area was declared s
cheduled tribe area in 1967. This article begins with the analysis of
the socio-economic situation of the Jaunsaries and identifies the role
and influence of polyandry in their social development and economic s
ustainability.
