China Can Be Self-sufficient In Maize Production By 2030 With Optimal Crop Management

This article examines the potential for China to become self-sufficient in maize production through the implementation of optimal planting density and management. Data from 402 stations and 87 field experiments across China were combined with a machine learning method to estimate a 52% yield improvement in the 2030s under a high-end climate forcing Shared Socio-Economic Pathway (SSP585). The results suggest that China can achieve food security through optimal crop-soil management under future climate change scenarios.
