六、代表性成果 (Representative Achievement)

During the last five years, the main scientific achievements were as follows: 1) clarified the global patterns and drivers of soil gross N mineralization, gross nitrification, gross N immobilization, and dissimilatory nitrate reduction to ammonium, 2) analyzed the global spatial variations of soil internal N cycling, 3) performed a detailed analysis of the N cycling patterns of 52 African countries from 1961 to 2016, and 4) suggested different scenarios of inorganic fertilizer N use and human diets to calculate the food N footprint and N fertilizer amount needed to achieve food self-sufficiency in Africa by 2050. I have published many articles as first author/corresponding author in excellent journals indexed by SCI (e.g., Nature Food, Global Change Biology, Environmental Science & Technology, Environment International, and Science of the Total Environment).
