1. 1. Towards climate optimised riparian buffer zones in boreal forests

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Alice Falk; [2022]
   Keywords : Forestry; Biogeochemical hotspots; Carbon dioxide; Methane;

   Abstract : Boreal forests have the potential to mitigate the increased concentrations of greenhouse gases (GHGs) in the atmosphere. However, forestry alters the soil biogeochemical processes which can cause an increase in GHG emissions from nearby water bodies, soil and vegetation. READ MORE

   Abstract : Wetlands are globally important biogeochemical hotspots, and their roles as either significant sources of greenhouse gas or carbon sinks are strongly controlled by environmental drivers such as carbon, nitrogen, and phosphorus availability, which can stimulate emission of three greenhouse gases: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). Mounting evidence suggests that aquatic invertebrate activity can enhance wetland greenhouse gas flux, through bioturbation and bioirrigation of surrounding sediments. READ MORE
