Soil organic carbon strategies

Some of the single-measure strategies tested for drought adaptation have also been analyzed for soil organic carbon changes, as obtained by the developed soil carbon model. Given that soil carbon differences would occur with strategies that involve significant land use changes, the following single-measure NBS strategies have been analyzed: wetlands resoration, heathlands restoration and tree planting, with their same spatial distribution (within the Dutch part of the Aa of Weerijs catchment), as introduced for drought-related adaptation. In addition, one strategy with extreme reforestation has been analyzed, covering the whole Aa of Weerijs catchment. Climate change scenarios do not play a role in this analysis. Soil organic carbon difference (SOCD) values are calculated for these different land use change adaptation strategies with respect to the base model (current conditions).
The figure to the right pesents an example of the SOCD calculations for the extreme reforestation adaptation strategy. See below the results of the Soil Organic Carbon Difference (SOCD) for all tested strategies.
