英文摘要Adequately feeding a growing population to achieve the Sustainable Development Goal of zero hunger is a key concern. Increasing the food supply until every individual has access to an adequate diet is essential for mitigating hunger. However, within this endeavor, the inequitable distribution of food emerges as a substantial impediment to the complete eradication of hunger. It's essential to ascertain whether the negative impact of food distribution on hunger eradication exceeds the positive impact of food supply. In this study, a decomposition analysis was performed to identify the contributions of key drivers affecting hunger risk in 158 countries from 2000 to 2018. We systematically applied an additive decomposition approach to break down the changes in the population at risk of hunger into factors such as population, prevalence of undernourishment (PoU), food supply, and food distribution. The decomposition analysis of global hunger risk revealed that the PoU changes reduced hunger. In contrast, population changes increased the number at risk of hunger. The average contribution of PoU to the hunger population reduction was higher than the average contribution of population changes in 2000-2018, which was 55 % and 32 %, respectively. In particular, the magnitude of the relative contribution of the two drivers reversed in low-income countries after 2008. We further decomposed PoU into food distribution, domestic food supply, and food trade. The results show that the contribution of inequality in food distribution partially or completely compensates for food supply in low-income countries. For food supply, cereals were a key pathway in domestic food supply and trade to reduce hunger. The magnitude of the contribution of cereals (22.98 %) was higher than others (mainly oilseeds) (4.02 %) and milk (3.10 %). For food distribution, worsening inequality in food distribution increased PoU, which contributed from 8.40 % to 13.74 %. Therefore, low-income countries must not only insist on high levels of cereal self-sufficiency to increase food supply but also achieve a more equitable distribution of food through targeted government support.
