Abstract. Understanding the spatial-temporal distribution of grazing livestock is crucial for assessing sustainability systems, managing animal diseases, mitigating climate change risks, and controlling greenhouse gas emissions. In China, ruminants are mostly distributed across vast grasslands in semi-humid alpine areas. However, existing datasets gridded China do not distinguish with other production nor capture their long-term seasonal dynamics, tend to overestimate distribution. This study uses county-level data from Grassland Ecological Protection Subsidies to differentiate forms rearing. Interpretable machine learning models were used detect seasonality pasture map China’s long-term annual ruminant distribution grazing livestock production systems 2000 2021 (CLRD-GLPS). The model's internal ten-fold cross-validation results (adjusted R2) cattle ranged 0.850 0.952 sheep 0.780 0.836. External validation using province-level meat yielded Pearson correlation coefficients 0.83–0.88 0.92–0.94 sheep, respectively. CLRD-GLPS provide more detailed, information on local than census-based data.

Anthropogenic climate change is expected to have major impacts on domesticated livestock, including increased heat stress in animals both intensive and extensive livestock systems.

Agroforestry systems have the potential to sequester carbon and offer numerous benefits rural communities, but their capacity valuable cooling services has not been quantified on continental scales. Here, we find that trees in pasturelands ("silvopasture") across Latin America Africa can substantial benefits. These increase linearly by -0.32 °C -2.4 per 10 metric tons of woody hectare, importantly do depend spatial extent silvopasture systems. Thus, even smallholders reap important from intensifying practices. We then map where realistic (but ambitious) expansion could counteract a fraction local projected warming 2050 due climate change. Our findings indicate what temperature increases global change help vulnerable communities adapt world.
