This study finds interesting outcomes regarding the interlinkage between the food, energy, and water sectors. The UN's Food and Agriculture Organization data from January 1961 till January 2023 are employed for six variables, namely Total Renewable Water resources per capita (TRW), Total Internal Renewable Water resources per capita (TIRW), Total Water Withdrawal per capita (TWW), Global Food Consumption per capita (GFC), Global Crop Production (GCP), and Global Electricity Consumption (GEC). Employing Quantile Vector Auto-Regression (QVAR) methodology, we observe asymmetry in connectedness across quantiles. Positive shocks produce stronger impacts in the variables than negative ones. Crop production mostly acts as a receiver of shocks. Renewable water is a consistent net emitter in all circumstances, while water withdrawal is crucial during negative shocks regime as well as in neutral time.

粮食、能源和水的关系：相互关联性和权衡研究

这项研究发现了有关食品、能源和水部门之间相互联系的有趣结果。联合国粮食及农业组织1961年1月至2023年1月的数据用于六个变量，即人均可再生水资源总量（TRW）、人均内部可再生水资源总量（TIRW）、人均取水总量（TWW）、全球人均粮食消费量 (GFC)、全球农作物产量 (GCP) 和全球电力消耗量 (GEC)。采用分位数向量自回归 (QVAR) 方法，我们观察到分位数之间连通性的不对称性。正面冲击对变量产生的影响比负面冲击更强。农作物生产主要充当冲击的承受者。在所有情况下，可再生水都是持续的净排放量，而在负面冲击期间以及中性时期，取水至关重要。
