An Indigenous forest monitor receives a satellite alert showing possible deforestation within their territory. What happens next? Turning that alert into action requires trained monitors, equipment, and a place to coordinate the response before more forest is lost. Now, at the mouth of the Auaris River in northern Brazil, the Ye'kwana people have inaugurated a new hub to coordinate Indigenous-led monitoring in the region. From here, monitors can combine satellite data, drone imagery, and field reports to investigate incursions, document environmental damage, and organize a response. The hub is one of more than a dozen planned across strategic river basins in Yanomami territory, where illegal gold mining has devastated forests and waterways for decades and continues to threaten Indigenous communities. This effort is led by the Associação Wanasseduume Ye'kwana (SEDUUME) and supported by Rainforest Foundation US, with funding from the Danish International Development Agency (DANIDA) and other allies, in collaboration with Hutukara Yanomami Association, Urihi Associação Yanomami, and Instituto Socioambiental (ISA) @socioambiental .
