Abstract: Considering the uniqueness and complexity of food security challenges caused by climate change, this article proposes a novel research idea and approach based on the junction of natural sciences and social sciences. Econometric models are used to perform statistical analysis on climate change data and econometric methods to assess the causal relationship between external climate drivers and observed climate change. The author clarifies the “impact of climate change” on food production and estimate China’s climate change risks on food production in the next 30 years, especially at the two key nodes of economic and social development in 2035 and 2050. The article provides a novel research perspective, as well as research content and methodology. The goal is to blend qualitative and quantitative research and provide strong support with scientific projections for policymaking.
