Summary
This 2021 study employs process-based modelling to quantify the restoration gap in degraded Inner Mongolian grasslands—the difference between current degraded conditions and theoretically recoverable states. The spatially explicit modelling of soil and vegetation dynamics reveals that whilst restoration is biophysically feasible, substantial gaps persist between theoretical recovery potential and practical restoration outcomes. The findings indicate that both environmental constraints and management limitations significantly constrain grassland recovery rates in this region.
UK applicability
The methodology and process-based modelling approach may be transferable to UK upland and grassland restoration contexts, though the arid steppe conditions and specific degradation drivers in Inner Mongolia differ substantially from UK temperate grassland systems. UK applicability would depend on adaptation of model parameters and consideration of differing precipitation regimes, soil types, and management histories.
Key measures
Spatial and temporal vegetation cover recovery; soil property trajectories; restoration gap magnitude; biophysical and management limitation factors
Outcomes reported
The study quantified the restoration gap—the disparity between current degraded grassland state and theoretically achievable restoration endpoints—using spatially explicit process-based modelling. The research mapped soil and vegetation recovery dynamics across the Inner Mongolian steppe to identify biophysical and management constraints limiting practical restoration success.
