Estimating erosion rates using Cs-137 measurements and WATEM/SEDEM in a Mediterranean cultivated field

摘要

The loss of fertile topsoil is one of the principal soil degradation problems in agricultural landscapes worldwide. Mediterranean agroecosystems are particularly threatened to soil degradation because of the climate, a higher sensitivity to soil erosion and the intensification of human activities and agricultural practices during centuries. The severity of this problem and the expected increasing risk of soil erosion in Mediterranean cultivated landscapes as a consequence of climate change have generated a demand for estimations of soil redistribution rates and soil loss monitoring.
