Could tech replace firefighters in the battle against wildfires?

The pictures are familiar, terrifying fires being tackled by firefighters and planes dropping water.

Hundreds of thousands of people have been forced to leave their homes across France, Spain and Portugal as wildfires tore through forests and countryside.

In France, four men have already lost their lives fighting the wildfires and another 150 have been injured.

But why are humans and 30-year old planes being used? Why can drones replace soldiers in Ukraine but not firefighters?

Chief sergeant Guillaume Millet, a firefighter of 24 years experience heads the Fire and Rescue Service branch of the CFDT union in the Gironde, the region worst hit by wildfires in France this summer.

He says that while the techniques for tackling fire have not changed much, technology in forest fire detection has.

"The big change, especially in my département, is that now we've got cameras assisted by artificial intelligence to watch the forest and see where fires are starting," Millet says.

"In the Gironde, cameras have replaced the human look-outs we had in watch towers in every town throughout the summer months," he says. Those lookouts were often students.
