Rising in the savannas of the Cerrado and the wetlands of the Pantanal, the Paraná basin gathers water from four nations, Brazil, Bolivia, Paraguay and Argentina, and carries it south to the Río de la Plata. It is the second-largest river system in South America.
My work is to tell this river's story while science is still reading it. With support from the National Geographic Society, and alongside the Jaguar Rivers Initiative and MuCi, I follow the water from its headwaters in the Cerrado to the Esteros del Iberá, stopping for the stories it passes. In-depth photo essays travel with the expeditions.
Everything the expeditions gather flows into Jaguar Rivers Watch, a living map of the basin open to scientists and the public alike, growing with every journey until it holds the whole river.
The Jaguar Rivers Initiative brings together four conservation groups, Onçafari in Brazil, Nativa in Bolivia, Fundación Moisés Bertoni in Paraguay and Rewilding Argentina, to work at the scale of the whole basin. Founded in 2025, it rests on a simple conviction: rivers should not be borders that divide nations, but living corridors that connect them.
A confluence of satellite imagery, geospatial data and imagery from the ground, at a continental scale, to understand the Paraná basin and help protect its future.
