Data drawn from a global compilation of studies quantitatively confirm the long-articulated contention that erosion rates from conventionally plowed agricultural fields average 1-2 orders of magnitude greater than rates of soil production, erosion under native vegetation, and long-term geological erosion. The general equivalence of the latter indicates that, considered globally, hillslope soil ...

Wind erosion of soil is an appreciable but unstudied event following fires in cold desert. We examined aeolian transport of sediment for 1 year following fire in semi-arid shrub steppe on loess soils in southern Idaho, USA. Sediment collectors were used to determine horizontal mass transport of soil and saltation sensors and anemometers were used to determine saltation activity (fraction of tim...

1. introduction wind erosion is a major geomorphological force, especially in arid and semi-arid regions. it is also a major source of land degradation, evaporation, desertification, harmful airborne dust, and crop damage especially after being increased far above natural rates by human activities such as deforestation, urbanization, and agriculture. wind erosion removes sediment, damage crops,...

This study focuses on the glacial landform record associated with recent surge events of Tunabreen a calving tidewater glacier in Tempelfjorden, Spitsbergen. Submarine geomorphology and recent terminal fluctuations of Tunabreen’s glacier front were studied using high-resolution multibeambathymetric data and a range of published and remotesensing sources, including topographic maps, satellite im...

Lipari is the largest and most populated island in Aeolian Archipelago, a UNESCO site, highly frequented touristic destination. As many other insular settings, low-lying coastal stretches E NE sectors of are locally exposed to erosion flooding, enhanced by subsidence effects leading local sea level rise. Most these appear critical, being narrow increasingly threatened risk permanent inundation ...

Determinations of soil moisture and sediment availability in arid regions are important indicators of local climate variability and the potential for future dust storm events desertification. Data from the Advanced Spaceborne Thermal Emission and Reflection (ASTER) radiometer are used to derive the relationships amongst potential soil erosion, soil moisture and thermal inertia (TI) at the spati...
