Coordinating Food Security With Carbon Reduction and Sequestration in China

ABSTRACT Mitigating climate change while guaranteeing food security is an important issue. Currently, the coordination of food security, carbon reduction and sequestration (CRS) and its influencing mechanism are unclear. In this study, we analyze the interactions and influencing factors between the two using a geographically and temporally weighted regression (GTWR) model. The results show that the national coupling coordination degree (CCD) increased from 0.477 in 2001 to 0.508 in 2022, indicating a shift from dissonance to coordination. Significant regional heterogeneity exists in coupling coordination. The GTWR results reveal that the share of grain‐sown area, agricultural technology, labor quantity and quality, and mechanization exert significant positive effects on coordinated development, whereas chemical fertilizer use has a significant negative impact. Moreover, a U‐shaped relationship is identified between regional economic development and CCD, suggesting that economic growth initially constrains but eventually promotes coordinated development after surpassing a certain threshold. These findings highlight the need for region‐specific policy design, with a particular emphasis on improving education and human capital in western and southwestern China, as well as promoting the diffusion and application of agricultural technologies and mechanization.
