Albedo matters for the climate, and forestry can have an impact on it

A research project conducted by Aalto University found that favoring broadleaved species in boreal forestry is a climate-friendly option when considering the forest albedo. Therefore, forest management actions can directly affect forest albedo, and hence the climate, without decreasing forest productivity.

Vegetation cover and land-use changes alter the surface albedo, or the extent to which incoming solar radiation is reflected back to the atmosphere and outer space. Even though land surface albedo is a critical variable affecting our climate, it is still among the main uncertainties of the radiation budget in current climate modelling. Aalto University’s soon ending project funded by the Academy of Finland examined how changes in boreal forests affect albedo and its seasonal variation.
