The area burned by wildfires has increased in recent decades and is expected to increase in the future for many watersheds worldwide due to climate change. Burned areas within watersheds increase soil erosion rates, which can increase the downstream accumulation of sediment in rivers and reservoirs. Using an ensemble of climate, fire, and erosion models, we show that post-fire sedimentation is projected to increase for more than ¾ of watersheds by at least 10 % and for more than ¼ of watersheds by at least 100 % by the 2041 to 2050 decade in the western USA. In this region, 65 % of the water supply originates from forested lands that are prone to wildfire, and many of the watersheds with projected increases in sedimentation...
...About 300 miles away from Kolden’s office at the University of Idaho in Moscow, is the Boise office of the US Geological Survey (USGS)’s Western Geographic Science Center and the base of Jason Kreitler, a USGS research geographer. Like Kolden, Kreitler has spent considerable time thinking about the policies that shape wildland fire management. However, Kreitler is examining the problem with a different lens, using economics and social science. Kreitler explains his research focus like this: “We have fixed budgets for most, if not all, of our public land management, so the question is, how do we optimize the use of those funds to best meet our conservation goals, like protecting biodiversity or ecosystem services?...
Baltimore, MD, USA: In recent years, wildfires have burned trees and homes to the ground across many states in the western U.S., but the ground itself has not gotten away unscathed. Wildfires, which are on the rise throughout the west as a result of prolonged drought and climate change, can alter soil properties and make it more vulnerable to erosion. A new study shows that the increase in wildfires may double soil erosion in some western U.S. states by 2050, and all that dirt ends up in streams, clogging creeks and degrading water quality.

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
