British Columbia clear‑cut logging linked to higher flood risk
A University of British Columbia study near Summerland finds that clear‑cut logging significantly raises the risk of flooding in British Columbia. Professor Younes Alila and colleagues report that flood events once expected only once in 50 years are now occurring roughly once every five years, placing downstream communities under greater threat.
The researchers explain that removing forest canopy makes soils wetter and accelerates snow melt, while also increasing the likelihood of drought. Although climate change alone would tend to reduce flood risk, the study shows that extensive clear‑cutting more than offsets this benefit. BC has lost about 97 % of its most productive old‑growth forests over the past three to five decades, according to the authors.
The team—Alila, Spencer Pearson‑Atkins and Xu Jian (Joe) Yu—has been investigating flooding since 1996 and urges a shift away from indiscriminate clear‑cut practices toward more eco‑friendly logging methods.
