Savanna grasslands are important ecosystems on a worldwide scale, supporting human livelihoods through grazing while serving as habitats for a variety of flora and wildlife. In this research, the complex interactions between climate change, grazing patterns, and their combined effects on the dynamics of livestock weight and biomass in savanna ecosystems are examined by using Soil-Plant-Atmosphere Continuum System (SPACSYS) model. Three stocking rates were utilized for the treatment sites where samples were collected in the grazing experiment: no-grazed (NG) (0 TLU/ha/Y), moderately grazed (MG) (2 TLU/ha/Y), and over grazed (OG) (4 TLU/ha/Y and above). Using various stoking rates, the aboveground biomass of the grass species and changes in livestock weight were predicted under three typical concentration pathways (RCP) scenarios (RCP 2.6, RCP 4.5, and RCP 8.5), which mostly focused on the severe drought period running from 2020 to 2023. Our results highlight the importance of grazing management techniques for mitigating the negative impacts of climate change on livestock productivity and biomass output. In addition, we stress the crucial importance of adaptive management strategies that consider socioeconomic and ecological aspects to assure the sustainability and resilience of savanna grassland ecosystems in the face environmental change.
