The Brazilian government has said it will employ heat-seeking radar in a last-ditch attempt to save the country's remaining groups of isolated Indians. The body-heat sensors will be mounted on a Brazilian air force jet normally used to monitor rainforest destruction and will be used to locate an estimated 39 groups of isolated indigenous people, hidden deep in the Amazon rainforest.
The authorities hope the system will help them to locate groups of isolated Indians to protect them from invaders such as loggers, goldminers and ranchers.
Antenor Vaz, the coordinator for isolated tribes at Brazil's National Indian Foundation, said the system would allow authorities to locate tribes without disturbing their way of life.
"We have been using planes more and more, not just to monitor
but also to find new references," he said. But even the use of small planes brought disruption to the tribes because they flew at low altitude, he said.
Brazil's isolated Indians hit the headlines in May when aerial photographs of a remote tribe near the border with Peru were released. Several tribesmen could be seen firing arrows at the plane.
