Final answer:
Fraternal polyandry is a form of marriage practiced in Nepal and Tibet where one woman has multiple husbands, typically brothers, which helps with resource management and economic stability.
Step-by-step explanation:
In Nepal and Tibet, the form of marriage being described is known as fraternal polyandry. This unique marital arrangement involves a woman having more than one husband, typically brothers, which provides a safety net for the wife. In societies facing scarcity of resources and land, or where population control is a concern, this form of marriage is advantageous. Fraternal polyandry ensures that land inheritance is not fragmented and helps maintain economic stability within the family unit. One husband may work on the family farm, while another might seek employment in urban areas to bring in additional income.
This form of marriage minimizes reproduction and keeps the land within the family, allowing brothers to share the responsibility of providing for the family and maintaining the household collectively. This marital practice is effective in managing resources and provides social and economic benefits in regions where polyandrous marriages are practiced.
