Abstract：
Climate change is an imminent threat, particularly affecting agricultural productivity, which relies heavily on weather conditions. Understanding the specific impacts of climate change on key crops is crucial for developing effective adaptation strategies to ensure food security. The growth patterns of onions and garlic were observed at over ten different locations in South Korea, and the yield data from the past 40 years were analyzed. The yield was significantly correlated with temperature and strongly affected by the frequent and unexpected patterns of precipitation. The increase in mean temperature during winter and the spatial and temporal concentration of precipitation are expected to be the most influential factors for Allium crop production in the future. In addition, the yields of onions and garlic can serve as good indicators for predicting the impacts of weather on agricultural productivity, given their extended cultivation periods and significant correlations with temperature and precipitation. As climate change scenarios become available, the results of this study can serve as a basis for predicting changes in agricultural production in the future and identifying opportunities to adapt cultivation systems for food security.
摘要：
气候变化是一个迫在眉睫的威胁，特别是影响农业生产力，这在很大程度上依赖于天气条件。了解气候变化对主要作物的具体影响对于制定有效的适应战略以确保粮食安全至关重要。在韩国的十个不同地点观察到洋葱和大蒜的生长模式，并对过去40年的产量数据进行了分析。产量与温度显着相关，并且受到频繁和意外的降水模式的强烈影响。预计冬季平均温度的升高和降水的时空集中将是未来大蒜作物生产的最重要因素。此外,洋葱和大蒜的产量可以作为预测天气对农业生产力影响的良好指标，考虑到它们延长的栽培期以及与温度和降水的显着相关性。随着气候变化情景的出现，这项研究的结果可以作为预测未来农业生产变化和确定适应粮食安全的种植系统的机会的基础。
