Top Scientists gather in Dundee, Scotland to look into soils
Over 100 scientists from all over the world are gathering in Dundee this week to discuss the impact of soil on climate change. Experts from as far afield as South Africa will attend the two day event which is organised by the SIMBIOS Centre at the University of Abertay Dundee. Researchers and policy makers now recognise that soil’s importance as both a catalyst and indicator of climate change has until now been seriously underestimated, and that at worst its full impact could have dire effects. The worst case scenarios predicted by the Intergovernmental Panel on Climate Change (IPCC) as little ... |

Erosion after wildfires affect forest rehabilitation
Wildfires greatly increase hillslope- and watershed-scale runoff and sediment yields, according to research conducted by a group from Colorado State University and published in the Soil Science Society of America Journal. Land use and climate change have increased, or are projected to increase, the size and frequency of fires in many wildland environments. These issues are of concern because severe wildfires can increase stream flows and erosion rates by 10 to 100 times relative to undisturbed forests. The increases in water flow can cause downstream flooding, degrade public water supplies, fill ... |
