Q Zhang, J Dong*, Z Xu, W Nam, J Yang, Y Zhang, Y Qin, S Gao, S Huang, H Tian, Q Yu, Q Ge*
Nature Food, 2025
Media Outlet (Yonhap News Agency)

• The Democratic People’s Republic of Korea (DPRK) suffers greater agricultural losses than the Republic of Korea under milder droughts
• Energy shortages, exacerbated by trade sanctions, have limited the DPRK’s irrigation capacity, further impairing its drought resistance and food security

Coupling GEDI LiDAR and optical satellite for revealing large-scale maize lodging in Northeast China
Q Zhang, G Zhang*, Y Zhang*, X Xiao, N You, Z Li, H Tang, T Yang, Y Di, J Dong*
Earth’s Future, 2024

• The first application of GEDI in agricultural disaster assessment
• GEDI footprints can well reveal changes in maize height caused by typhoons
• LSWI provides a robust wall-to-wall mapping of crop lodging

Unraveling the spatial-temporal patterns of typhoon impacts on maize during the milk stage in Northeast China in 2020
Q Zhang, G Zhang, X Xiao, Y Zhang, N You, Y Di, T Yang, Y He, J Dong*
European Journal of Agronomy, 2024

• LSWI is the prior indicator for assessing typhoon disturbance in maize
• Week-long lagging impacts of typhoons on maize growth lasted until the end of the growing season
• Spatial-temporal compensation mitigates typhoon impacts on maize in the entire region

Spatiotemporal genotype replacement of H5N8 avian influenza viruses contributed to H5N1 emergence in 2021/2022 panzootic
J Zeng†, F Du†, L Xiao, H Sun, L Lu, W Lei, J Zheng, L Wang, S Shu, Y Li, Q Zhang, K Tang, Q Sun, C Zhang, H Long, Z Qiu, K Zhai, Z Li, G Zhang, Y Sun, D Wang, Z Zhang, SJ Lycett, GF Gao, Y Shu, J Liu, X Du*, J Pu*
Journal of Virology, 2024

• The 2020 outbreak of the H5N8 G1 genotype instead of the G0 genotype produced reassortment opportunities and led to the emergence of a new H5N1 virus with G1’s HA and MP genes
• The spatial-temporal coincidence between the outbreak of the H5N8 G1 virus and the bird autumn migration may have expanded the H5 viral spread
