Harvested carbon dataset of cropland in China

We have created a dataset that conducts a comprehensive analysis of carbon harvested from crop production in China over a 40-year period from 1981 to 2020. This dataset has a spatial resolution of 10x10 km, categorizes arable land into five types, and shows that cereal crops account for the largest proportion of total carbon harvested, at 75.9%. Over the past 40 years, the average carbon harvested in agricultural ecosystems was 0.31 Gt C yr-1. This dataset is expected to aid in estimating the carbon budget of arable ecosystems and of China as a whole. The data are available through open data repositories, providing valuable insights for research and policy-making aimed at sustainable agriculture and mitigating climate change.
