For International Day for Disaster Risk Reduction (October 13th), we're finding out how technology can help prevent disasters, save lives and help rescuers. In Argentina, we’ll meet Franco Rodríguez Viau whose family friends lost their home in a fire, inspiring him to find a way of tracking wildfires. He was just a teenager when he began developing an app that combines NASA satellite imagery with other data sources to identify and intercept fires before they become unmanageable. Meanwhile in Colombia, podcasters and sound engineers tell us about using their specialist recording equipment and live analysis of sound to detect breathing and tapping beneath earthquake rubble, helping rescuers locate survivors. People Fixing The World from the BBC is about brilliant solutions to the world's problems. We'd love you to let us know what you think and to hear about your own solutions. You can contact us on WhatsApp by messaging +44 8000 321721 or email peoplefixingtheworld@bbc.co.uk. We release a new edition every Wednesday - just search for The Documentary wherever you get your podcasts.
