Description :
The AA. assess the extent to which common land domestic grazing pressures were the primary external force causing soil erosion and land degradation during the period of occupation from ca. 874 AD in Southern Iceland. They first provide field observation of soil erosion, temporally defined by tephrochronology, to highlight the extent of land degradation during this period. The tragedy of the commons explanation of degradation is then assessed by evaluating historic documentary sources, and by environmental reconstruction and modeling of historic grazing pressures.
