“…As of 2021, over 828 million people globally are undernourished and experience hunger, and the number of undernourished individuals are increasing [3]. The consequences of the COVID-19 pandemic are expected to worsen the world food crisis [4]. In addition, the UN's forecast that the world's population will surpass 8.5 billion people in 2023 and 9.8 billion people by 2050, along with an increase in emerging nations' incomes, will drive up food consumption further.…”

Applying new designs and business formats to production and consumption patterns as part of the circular economy (CE), an increasingly popular concept within environmental research, ensures sustainable food production practices and fosters environmental sustainability. The CE approach is particularly relevant in arid regions, such as the Kingdom of Saudi Arabia (KSA), challenged by extremely harsh climates where natural resources are both scarce and excessively exploited. This study thus aims to show how the CE concept can be applied to the food sector in the KSA by identifying relevant issues and related CE strategies through a literature review. The CE framework is presented to explain sectoral challenges at the macro and meso levels and maps the associated circular strategies with specific models and corresponding examples of industrial applications in. Finally, circular strategies from the mapping are compared with the current situation in the country to identify where they are already practiced, identify gaps and priorities, and outline prospects. Effective management of food loss and waste requires a timely, holistic strategy to add value to the sustainable development goals (SDGs) outlined in the Saudi Arabia Vision 2030 and SDG 12.3 target that aims to reduce the rates of food loss and waste by 50% by 2030.

“…Since the outbreak of the COVID-19 pandemic in 2019, food security has faced unprecedented challenges. A limited number of scholars have assessed the pandemic's adverse effects and proposed improvements to food security early warning and response mechanisms (Béné et al 2021;Yao et al 2023). Collectively, these scholars have delineated the concept and scope of food security from various angles and have explored the pathways through which different factors in uence food security.…”

Food security is a vital material foundation for a nation's development and has been a topic of significant concern on the international stage in recent years. With a population exceeding 1.4 billion, China is not only a major producer but also a substantial consumer of food. Ensuring food security in China is not only a top priority for its socio-economic development but also a driving force in maintaining the stability of the global food supply chain and reducing the number of hungry people worldwide. However, a lack of comprehensive research into the Chinese food security system remains. This study addresses this gap by constructing a comprehensive evaluation framework encompassing four dimensions: food supply, accessibility, production stability, and sustainability. Utilizing the Moran's Index and generating LISA (Local Indicators of Spatial Association) maps, we analyze the spatial correlations of food security. The Dagum Gini coefficient and kernel density estimation are applied to assess heterogeneity and spatial disparities. Furthermore, this research employs an ETS model to forecast food security trends. The findings reveal that the overall composite food security score exhibited fluctuations, initially increasing and reaching its peak of 0.407 in 2003, followed by a subsequent sharp decline after 2019. Spatially, food security exhibits correlations, with the Huang-Huai-Hai Plain and Northeast regions consistently showing high-high clustering. In contrast, the Western and Southern regions exhibit low-low clustering at specific time periods. The Dagum Gini coefficient indicates that overall food security disparities are relatively small. However, these disparities have gradually expanded in recent years, with inter-group differences becoming predominant after 2005.As indicated by the kernel density estimation, the dynamic distribution of food security initially widens and then narrows, suggesting a shift from dispersed to concentrated data distribution. This phenomenon is accompanied by polarization and convergence trends, particularly evident after 2015. According to the ETS Model, the study forecasts a substantial risk of declining food security in China over the next decade, largely influenced by the ongoing pandemic. In conclusion, this research provides a comprehensive assessment of the changing status of food security in China and offers early warnings through predictive analysis, addressing the existing research gaps in the field of food security.

Although the SARS-CoV-2 vaccination is the primary preventive intervention, there are still few antiviral therapies available, with current drugs decreasing viral replication once the virus is intracellular. Adding novel drugs to target additional points in the viral life cycle is paramount in preventing future pandemics. The purpose of this study was to create and test a novel protein to decrease SARS-CoV-2 replication. We created the recombinant rod domain of vimentin (rhRod) in E. coli and used biolayer interferometry to measure its affinity to the SARS-CoV-2 S1S2 spike protein and the ability to block the SARS-CoV-2–ACE2 interaction. We performed plaque assays to measure rhRod’s effect on SARS-CoV-2 replication in Vero E6 cells. Finally, we measured lung inflammation in SARS-CoV-2-exposed K18-hACE transgenic mice given intranasal and intraperitoneal rhRod. We found that rhRod has a high affinity for the S1S2 protein with a strong ability to block S1S2–ACE2 interactions. The daily addition of rhRod decreased viral replication in Vero E6 cells starting at 48 h at concentrations >1 µM. Finally, SARS-CoV-2-infected mice receiving rhRod had decreased lung inflammation compared to mock-treated animals. Based on our data, rhRod decreases SARS-CoV-2 replication in vitro and lung inflammation in vivo. Future studies will need to evaluate the protective effects of rhRod against additional viral variants and identify the optimal dosing scheme that both prevents viral replication and host lung injury.
