To build soil protection map, we use land use/land cover layer extracted from LANDSAT 7 ETM + images in addition to vegetation cover layer derived from MODIS NDVI product.
The good news is that while it may take hundreds of years to geologically build soil, farmers have demonstrated that they can increase organic matter and improve soil function in just a few years, through soil health management systems.
These ways have to use natural systems channeling solar power through crops, pasture and humanely raised livestock that builds soil carbon, doesn't pollute our water and increases economic opportunity for food producers in rural and urban areas.
