To What Extent Did We Change Our Soils? A Global Comparison of Natural and Current Conditions

摘要: The food security–climate change nexus rapidly gains momentum. Soil degradation plays an important role in this context while dealing with, for example, the productive capacity of our soil resources or carbon sequestration climate mitigation. However, little has been done to assess pristine conditions despite fact that these provide basis put changes into context. Various methodologies have developed global distribution current conditions. We used S-World methodology was generate property maps environmental modelling studies. Up till now, assessed by disaggregating Harmonized World Database using detailed information on climate, topography, land cover, and use. This study derive under natural vegetation. A large number areas around globe were identified which expressed Normalized Difference Vegetation Index, could be successfully correlated such as temperature, rainfall, topography. Using relation regression kriging, vegetation index derived entire globe. Subsequently, calculate properties cover absence human compared showed local differences. results indicate there are major due use concentrated future assessments on, degradation, security, sustainable development goals. © 2017 Authors.
