Climate change is a significant global concern, affecting ecosystems, human societies, and daily life. South Korea is particularly vulnerable to climate change, experiencing increasing temperatures and more frequent severe weather events. These meteorological changes influence consumers to adjust their consumption patterns, as demonstrated in previous research. This study examines the specific effects of climate change on food consumption patterns at the district level in South Korea, focusing on Home Meal Replacement (HMR) products. While previous studies have explored socioeconomic and demographic factors affecting HMR consumption, this study investigates the influence of meteorological factors such as temperature, humidity, precipitation, and extreme weather events. spatial autocorrelation and the distribution of HMR consumption patterns among 250 districts were analyzed using Moran's I test and Local Indicators of spatial Association (LISA) analysis. The global Moran's I was found to be 0.83, justifying the use of a spatial model. Additionally, a panel spatial error model was employed to assess factors explaining HMR consumption patterns, considering spatial heterogeneity and spillover effects between adjacent areas. The findings confirm that increased average temperature leads to higher consumption of HMR products, while high average humidity is associated with decreased consumption. Moreover, higher consumption patterns are clustered in metropolitan areas, while lower consumption patterns are observed in non-metropolitan areas with higher concentrations of elderly populations. These findings enhance our understanding of how climate change, as well as demographic and socioeconomic factors, influence HMR consumption at the district level in South Korea.

The impact of human-caused environmental pollution and global climate change on the economy and society can no longer be underestimated. Agriculture is the most directly and vulnerably affected sector by climate change. This study used beans, the food crop with the largest supply and demand gap in China, as the research object and established a panel spatial error model consisting of multiple indicators of four factors: climate environment, economic market, human planting behavior and technical development level of 25 provinces in China from 2005 to 2019 to explore the impact of climate environmental changes on the yields of beans. The study shows that: (1) The increase in precipitation has a significant positive effect on bean yields;however, the increase in temperature year by year has a significant negative effect on bean yields;(2) carbon emissions do not directly affect bean production at present but may have an indirect impact on bean production;(3) artificial irrigation and fertilization behavior on bean production has basically reached saturation, making it difficult to continue to increase bean yields and (4) the development of technology and human activity is a mixed blessing, and the consequent inhibiting effects on bean production are currently unable to offset their promoting effects. Thus, when it comes to bean cultivation, China should focus mainly on the overall impact of environmental changes on its production, rather than technical enhancements such as irrigation and fertilization.
