An image captured by the artist’s custom-built multispectral video camera mounted to the nose of an aircraft and flown over Yanomami Territory in Roraima, on the Brazil-Venezuela border. The artist worked with a machine-vision spectronomy engineer to build the camera, which emulates remote sensing cameras in satellites that monitor the Earth’s environment. It is a digital multi-sensor array involving beam splitters, which captures discrete narrow bands of spectral reflectance in a very specific range, only around ten or twenty nanometers each, reflected off the earth below. GIS scientists use this technology to reveal very specific environmental information, such as ecological degradation, which is expressed as colour. The Uraricoera River in Yanomami Territory has been overrun by at least 20,000 illegal gold miners (garimpeiros) in recent years, who illegally mine deep within protected Yanomami ancestral territory, often pressing vulnerable Indigenous people to work in the mines or as prostitutes, while spreading diseases such as malaria and diarrhoea. The river itself is devastated by the extractive violence of widespread hydraulic mining and gold dredges, turning the water a milky light blue. The water itself carries mercury, a by-product of the mining process, poisoning aquatic life and all who live off it, including Indigenous communities.
