Short summary
Short summary
In dynamic global vegetation models (DGVMs), the role of functional diversity in forage supply and soil organic carbon storage of grasslands is not explicitly taken into account. We introduced functional diversity into the Lund Potsdam Jena managed Land (LPJmL) DGVM using CSR theory. The new model reproduced well-known trade-offs between plant traits and can be used to quantify the role of functional diversity in climate change mitigation using different functional diversity scenarios.

Short summary
Short summary
Land use change (LUC) and conventional tillage (CT) are resulting in the reduction of the high soil organic carbon (SOC) stocks stored in grassland ecosystems during their conversion and renovation, contributing thus to global warming. Using no-tillage (NT) is seen as an avenue to minimize or even conserve SOC stocks during these events. Our results show that SOC losses are greatly reduced after grassland conversion to arable land, whereas during renovation it contributes to conserve them.

Short summary
Long-term studies on the impact of land use change and crop selection on soil organic carbon (SOC) stocks in sub-Saharan Africa are scarce. Accordingly, this study analysed the impact of converting natural grasslands to a range of low-input production systems in a tropical savannah on SOC stocks. Apart from the cultivation of legume tree and/or shrub species, all land management techniques were detrimental. Grazed grasslands in particular had almost 50 % less SOC than natural grasslands.
Long-term studies on the impact of land use change and crop selection on soil organic carbon...
