The Science of Soil: Using radionuclides to support soil conservation
Land degradation and soil erosion threaten agricultural productivity, food security and environmental sustainability. Because formation of new soil takes place over a period of thousands of years, in human terms it is essentially a finite resource. Human activity has accelerated erosion rates through inappropriate land management practices, most importantly soil sealing, deforestation and inten...
متن کاملValuing Soil Conservation Benefits of Agroforestry Practices
Although advocates of agroforestry have promoted soil conservation as one of its primary benefits, empirical estimates of these benefits have been lacking due to temporal and spatial complexity of agroforestry systems and soil resource dynamics. This study aims to reduce this gap by designing and testing a three stage farm level productivity methodology for economic evaluation of soil conservat...
