Ribeirinhos are the traditional river-dwelling people of the Amazon basin, whose communities line the waterways of the rainforest. They live primarily through small-scale fishing and subsistence farming, residing in pile dwellings raised above the seasonal flood waters and travelling between settlements in motor boats known as voadeiras.
Anthropologists trace their cultural lineage to both indigenous Amazonians and migrants who settled along the riverbanks following the collapse of the rubber industry in the early twentieth century. This heritage shows clearly in their agricultural methods and forest knowledge, which reflect generations of adaptation to the tropical riverine environment. Despite their role as long-term custodians of the river systems, ribeirinho communities face persistent challenges: limited employment opportunities, inadequate access to medical and dental care, and contaminated drinking water contribute to high mortality rates among children under five from water-borne diseases.
