Short summary
Short summary
This study presents an experimental framework (EF-SPM) to disentangle and evaluate the benefits of spatially explicit parameterization and multi-gauge calibration in distributed hydrological modelling. Intensive experiments in a nested catchment show that both strategies consistently improve streamflow simulations across sub-basins, while exhibiting a trade-off in parameter identifiability, with their cross-benefit manifested in an effective alleviation of multi-objective competition.

Short summary
Using satellite images and soil samples, we found that 39 065 km2 of farmland was retired across China’s Loess Plateau from 2000 to 2021, with nearly half converted to grasslands. Over two decades, these restored lands captured 21.77 million metric tons of carbon, Grasslands contributed over 80 % of this carbon storage, highlighting their critical role in climate mitigation.
