This study provides a comprehensive analysis of the factors influencing rice and corn yields in North Korea, focusing on weather variables, extreme weather events, and fertilizer inputs. Using fixed effects (FE) and fixed effects individual slope (FEIS) models with panel data, this study revealed a significant association between increased growing degree days (GDD) during the rice-growing season or increased precipitation during the corn-sowing season and increased yield for the respective crop. Conversely, increased precipitation during the rice harvesting season, as well as heatwave days and heavy rainfall during the growing season, negatively affected rice yield.
The technology trend variable in the FEIS model suggests regional variations in technological growth. These findings underscore the potential for enhancing crop productivity in North Korea through targeted interventions, including seasonal planning, harvest timing strategies, climate resilience, fertilizer optimization, technology adoption, and regional planning. The results offer valuable insights for policymakers, researchers, practitioners, and other participants in North Korea, emphasizing the importance of understanding the complex relationships between climate, technology, inputs, and yields in the unique context of North Korea.
