Modern twist on wildfire management methods has a bonus feature that protects water supplies

Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires was on average $106 billion per year between 2014 and 2023. The US is especially prone: the 10 most costly wildfires since 1970 all happened there, with the 2025 wildfires around Los Angeles topping the charts at $53 billion. Worldwide, wildfires destroyed 3.9 million km2 in 2025.
