  5. Land degradation along a climatic gradient in Mali: Farmers' perceptions of causes and impacts

    Abstract, Wiley Online, 2020 Land degradation (LD) in Mali is prevalent and leads to an enduring environmental and humanitarian crisis. Farmers' ecological knowledge has proven to be a valuable tool in addressing its challenges. How farmers perceive LD affects how they deal with induced risks,...

  6. Soil Erosion

    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...

  7. SOIL EROSION: The Greatest Challenge for Sustainable Soil Management

    20/01/2019 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...

  8. Soil Erosion

    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...

  9. Effective soil erosion control represents a significant net carbon sequestration

    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...
