Hi folks –
Is anyone aware of sensitivity analyses that have compared soil carbon estimates based on land cover-based lookup tables (InVEST carbon) as opposed to using modeled soil carbon data, e.g., from SoilGrids 250 m and combining those soil carbon data with vegetation carbon modeled using InVEST?
I’m wondering whether there’s any evidence in favor of using lookup tables for vegetation and soil carbon combined (i.e., using InVEST for the whole carbon storage analysis) vs. using InVEST for vegetation carbon storage (aboveground + belowground + woody debris) and combining that sum with raster data from SoilGrids or local soil carbon storage datasets.
I suppose a big part of the answer would depend on how much we’d expect soil carbon storage to change as land use/cover does (i.e., since the soil carbon spatial datasets are essentially static). Thanks to anyone able to shed some light on this issue!
