Soils are the main terrestrial reservoir of organic carbon, nitrogen and phosphorus. Thus, any type of disturbance, e.g. landuse changes, that alters soil integrity is a threat to planetaryscale biogeochemical cycles that sustain the life-support systems of the Earth. Soil erosion impacts the...

20 មករា 2019 Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those...

While knowledge of how soil erosion occurs and how to control it is firmly established, more research is needed on how to measure soil loss rates and budget for measures to reduce them - remain under debate. Indeed, there is disagreement over whether erosion turns soil into a source or sink for...

Abstract, Scientific Reports, 2018 The debate over whether soil erosion is a carbon (C) sink or atmospheric CO2source remains highly controversial. For the first time, we report the magnitude of C stabilization associated with soil erosion control for an entire large river basin. The soil erosion...

Abstract, Land Degradation and Development 2018 Soils are vital for supporting food security and other ecosystem services. Climate change can affect soil functions both directly and indirectly. Direct effects include temperature, precipitation, and moisture regime changes. Indirect effects...

Abstract, Environmental Research Letters, 2018 Implementation of socially acceptable and environmentally desirable solutions to soil erosion challenges is often limited by (1) fundamental gaps between the evidence bases of different disciplines and (2) an implementation gap between science-based...
