Abstract

The COVID-19 pandemic triggered a global crisis with unanticipated and diverse consequences. Moreover, the pandemic has considerably impacted food dynamics in low- and middle-income countries (LMICs), where food systems have already been challenged. These countries also have the highest share of the world's malnourished and food insecure. Therefore, this paper aims to analyze the pandemic's impact on food security dimensions (availability, accessibility, utilization, and stability), with a special emphasis on LMICs. According to the results, the pandemic immediately impacted food security by limiting food production and availability. It also had an indirect impact when lockdowns and other confinement measures (e.g., social distancing, movement restrictions) made it more difficult for individuals to access food and maintain a healthy, balanced diet (cf. food utilization). Indeed, with rising unemployment and poverty, access to food has been the most critically undermined aspect of food security. At the utilization level, COVID-19 adversely influences the nutritional state of both individuals and countries, leading to an increase in all forms of malnutrition. Finally, the impact of COVID-19 on the stability dimension is dependent on the length of the pandemic as well as the effectiveness with which recovery plans are followed to ensure universal vaccine availability, among other factors. As a result, including agricultural and food systems in recovery strategies is crucial to mitigating the pandemic's long-term effects on food security.

摘要

新冠疫情引发了一场全球危机,带来了意想不到的多样后果。此外,这场疫情对低收入和中等收入国家(LMICs)的粮食动态产生了重大影响,而这些国家的粮食系统原本就面临挑战。这些国家也是全球营养不良和粮食不安全人口占比最高的地区。因此,本文旨在分析疫情对粮食安全各维度(供应、获取、利用和稳定性)的影响,特别关注低收入和中等收入国家。根据研究结果,疫情通过限制粮食生产和供应,立即对粮食安全产生了影响。当封锁和其他限制措施(如社交距离、行动限制)使个人获取食物和维持健康、均衡饮食变得更加困难时(参见粮食利用),疫情还产生了间接影响。事实上,随着失业率和贫困率上升,获取食物已成为粮食安全最受严重影响的方面。在利用层面,新冠疫情对个人和国家的营养状况都产生了不利影响,导致各种形式的营养不良情况增加。最后,新冠疫情对稳定性维度的影响取决于疫情持续的时间以及确保普遍获得疫苗等恢复计划的执行效果等因素。因此,将农业和粮食系统纳入恢复战略对于减轻疫情对粮食安全的长期影响至关重要。
