Climate resilience promotion in China’s crop production with agricultural mechanization from 1995 to 2020 Dan Fang, Jiangqiang Chen, Saige Wang, Bin Chen

Abstract

With the increasing frequency of extreme weather events, promoting crop production’s resilience to combat climate disaster is urgent for global food security, however, the driving factors of crop production’s resilience are not yet clear to figure out the effective measures to improve it. At the same time, the benefits of agricultural mechanization, especially on resilience are not fully adopted, which may offer solutions for climate change adaptation. Here, we propose a crop production’s climate resilience driving factors assessment framework based on modified Pressure-State-Response concept and two-way fixed effect model. Taking China as the study area, we figure out the spatio-temporal evolution of crop production’s climate resilience and analyze the effect of rapidly developed agricultural mechanization on it. Our primary results show that food production’s climate resilience in China has been promoted since 2005, although drought and flooding events are gradually becoming more frequent. Complementarity among Chinese provinces enhances overall national food production’s climate resilience, to which Jilin Province and Xinjiang Province contributed the most. Due to timely policy adjustments, the autumn harvest has played an increasingly important role in enhancing resilience. Besides, agricultural mechanization played a significant role in guaranteeing food productivity to tackle climate impact. By analyzing the effect of agricultural mechanization on food production’s climate resilience in China, this study can provide insights for strengthening agriculture sector’s resilience and thus avoiding disruptions in food supply chains.
