North Bihar is a flood-prone region and every village and Mohalla in this region is either bisected by small and big rivers flowing from the Nepal Himalaya or surrounded by ponds and wetlands locally known as chaurs. The communities living in the Kosi villages are mainly dependent on agriculture and fishing. When there is no work at agricultural fields, men from most of the lower caste communities including Musahar and Mallah, two of the most marginalized communities, out-migrate for labour work in other states of India and to Nepal for selling ice-cream on a bicycle. The women live in the villages throughout the year somehow managing the family with money sent by their husbands and sons, they also work in fields and earn wages in the village. Apart from earning a wage, they also collect fuelwood, fodder for cattle as well as edible plants and animals from the wetlands or chaur area in both wet and dry seasons. Pila globosa or apple snail is one of the most consumed Mollusca among Musahar and Mallah communities. It is found in the paddy fields and wetlands in North Bihar in great numbers and cherished as one of the easily available sources of protein.
