Janet Pungin, a mother of four in her 50s, is responsible for farming and raising livestock in her household, especially caring for pigs.
“Because pigs are valued in Engan culture, it is my responsibility to ensure that our pigs are fed and taken care of. Pigs are fed sweet potato so it is important there is a constant supply of feed for the pigs,” she said.
