Vegetation can help prevent soil erosion due to wind (Sahel region of Africa)

ScienceDaily (January 20, 2015)

Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate. Investigators compared different models that quantify how the wind energy spreads over an herbaceous surface using data from the Sahel region of Africa, where estimates of dust emissions remain uncertain. They found that the modeling tools give results in reasonable agreement, indicating that vegetation can decrease the amount of dust emitted from soil erosion by 6% to 26% in mass compared with bare soil.
