ABSTRACT

Food is the fundamental guarantee of people's lives, and the food industry has always occupied an essential position in the national economy. Profit growth rate, as a measure of an enterprise's development ability, can intuitively reflect the change in operating profit for food enterprises. The accurate prediction of profit growth rate can provide a decision-making reference for enterprises in planning business objectives in the next stage. However, many factors affect the profit variation of a company, and it is hard to make accurate predictions using traditional statistical economics forecasting methods. Since the Long-Short Term Memory (LSTM) model can capture nonlinear relationships in time series analysis, we propose an LSTM-based model to predict the profit growth rate of enterprises by using the operational data of four seasons ahead. Moreover, due to the COVID-19 pandemic, the impact of supply chain integrity on enterprise operations is increasing. We introduce the information of the supply chain owned by the enterprise to predict the profit growth rate of the enterprise. The result of our model exhibits high prediction accuracy, which indicates that our model could provide practical guidance for companies' production and operation activities. © 2022 The authors and IOS Press.

ABSTRACT

Globally, COVID-19 has impacted lives and livelihoods. Women living with HIV and/or at high risk of acquiring HIV are socially and economically vulnerable. Less is known of the impact of COVID-19 public health responses on women from key and vulnerable populations. The purpose of this cross-sectional survey conducted in four South African provinces with a high burden of HIV and COVID-19 from September to November 2021 was to advance understanding of the socio-economic and health care access impact of COVID-19 on women living with HIV or at high risk of acquiring HIV. A total of 2 812 women >15 years old completed the survey. Approximately 31% reported a decrease in income since the start of the pandemic, and 43% an increase in food insecurity. Among those accessing health services, 37% and 36% reported that COVID-19 had impacted their access to HIV and family planning services respectively. Economic and service disruptions were enhanced by living in informal housing, urbanisation and being in the Western Cape. Food insecurity was increased by being a migrant, having fewer people contributing to the household, having children and experience of gender-based violence. Family planning service disruptions were greater for sex workers and having fewer people contributing to the household. These differentiated impacts on income, food security, access to HIV and family planning services were mediated by age, housing, social cohesion, employment and household income, highlighting the need for improved structural and systemic interventions to reduce the vulnerability of women living with HIV or at high risk of acquiring HIV.

ABSTRACT

India experienced a rapid rise in COVID-19 infections from March 2021. States imposed varying levels of lockdowns and curfews to curb the spread of the disease. These restrictions severely affected the functioning of food systems. The objective of this study was to analyze how COVID-19 continues to affect agricultural production, food security and household diets of vegetable farmers. A phone-based survey was conducted with 595 vegetable farmers in the states of Andhra Pradesh, Assam, Jharkhand, Karnataka and Odisha, 60% of whom had been interviewed a year earlier. Overall, 60% of farmers experienced decreased vegetable production;over 80% reported a reduction in consumption of at least one food group;and 45% reported some level of food insecurity between May 2020 and May 2021. Farmers who reported decreased staples production, difficulty accessing seeds/seedlings, or reduced their household spending were more likely to report decreased vegetable production. Vegetable consumption was positively associated with receipt of COVID-19 relief benefits, borrowing money, or having home gardens. Farmers who received public agricultural assistance, or had reduced expenses, were more likely to have lower vegetable consumption. Greater severity of food insecurity was associated with farmers belonging to underprivileged social groups, non-Hindus, or those who experienced decrease in livestock production, weather related disruptions or received COVID-19 assistance. This is one of few studies that have conducted a longitudinal assessment of the impacts across multiple waves of COVID-19. COVID-19 is seen to be one among several shocks experienced by farm households, and exacerbated existing issues within agriculture and food security. There is a need for public policy support to strengthen both production and consumption of vegetables.

ABSTRACT

The pandemic of the COVID-19 has caused many problems in the cross-border food supply chain during transportation, such as food safety is difficult to guarantee due to the infection of people or environmental epidemics, information asymmetry and difficult to share in the food supply chain, and food related information is tampered with and difficult to trace during transportation. The emergence of blockchain technology has brought new solutions to the above problems. Based on the relevant functions and characteristics of the blockchain, this paper constructs a cross-border food supply chain information sharing platform under the blockchain technology, such as using smart contracts to monitor the epidemic security risk in the transportation process of the supply chain, using hash functions and tamper proof features to deal with food information fraud, and using the distributed and decentralized characteristics of the blockchain to solve the sharing problem of information asymmetry;The time stamp in the blockchain is used to trace the information of each link node of food and the initial node for accountability. In this paper, the construction process of the platform is described in detail from the perspective of model, function and subject, and the specific process of the platform is described in detail from the perspective of information storage, information sharing and information traceability. In this paper, the emerging blockchain technology is applied to all links of the food supply chain, and considering the current epidemic problems, the platform can bring new ideas to solve the problems of cross-border food transportation during the epidemic, and has certain theoretical value. © 2022 Association for Computing Machinery.

ABSTRACT

This research full paper presents screening rates for mental health issues and life-stress events in engineering-focused community college students during the initial phases of the COVID-19 pandemic in the US. Specifically, it attempts to answer the following research questions: 1) What is the overall rate of various mental health conditions among engineering-focused community college students, 2) What effects has the pandemic had on baseline stress levels engineering-focused community college, and 3) What effects has the pandemic had on quality of life, such as sleep habits and financial security of engineering-focused community college students?Data for this paper was collected via survey from May-July 2020 and includes responses from 84 students at 24 community colleges. The survey itself was a compilation of several widely-used instruments for measuring overall mental health and stress levels in a population. These instruments include the Kessler-6 for psychological distress, the PHQ for anxiety, depression, and eating disorders, the PC-PTSD for PTSD-like symptoms, and the SRRS for inventorying stressful life events.Among the major findings, 32% of respondents reported a major change in financial situation, 27% reported loss of employment, and 13% reported ceasing formal schooling because of the COVID-19 pandemic. Additionally, 32% of respondents reported that the COVID-19 pandemic worsened their housing security situation, 38% reported that COVID-19 has worsened their food security situation, and 36% report that COVID-19 has decreased their ability to access instruction, course materials, or course supplies. Finally, of respondents who completed at least one mental health screening instrument, 70% screened positive for at least one potentially diagnosable condition, while only 9% reported ever receiving a mental health diagnosis. © 2022 IEEE.

ABSTRACT

PurposeThis study aims to the development of the scale of supply chain performance measures (SCPMs), food supply chain resilience (FSCS) and sustainable corporate performance (SCP) in small- and medium-sized enterprises (SMEs) in an emerging market. Based on this purpose, the study examines the relationships between SCPMs and SCP by exploring the mediating role of FSCS in emerging markets.Design/methodology/approachBased on a comprehensive literature review on the SCPMs, FSCS and SCP, the author evaluates the nexus of these constructs on disruptions during the COVID-19 pandemic emergency in an emerging market. The article follows a quantitative approach. A total of 567 valid responses from managers at senior and middle levels were received and used for data analysis. The Smart PLS version 3.3.2 was employed to analyse Structural Equation Modelling (SEM) to investigate the relationships between constructs and latent variables.FindingsThis study provides some theoretical contributions to expand the extant literature on the domain of SCPMs. First, the findings determine that multidimensional measures of flexibility, diversity, agility, inventory efficiency, redundancy and robustness are appropriate for measuring food SC performance in disruptions during the COVID-19 emergency. Besides, this study enriches the existing literature on SC disruption by providing extensive empirical evidence on SCPMs in disruptions during the COVID-19 emergency. Finally, this research provides an integrated empirical model that explores the link between the identified food SCPMs to FSCS and SCP.Originality/valueThe contributions may be of interest to business practitioners, business leaders and academics. In addition, this study provides empirical evidence to demonstrate that food SC performance, as measured by these measures, is strongly related to the firm's food supply chain resilience. This is the novel contribution of this study to the current literature on food SC management. Furthermore, this study provides further empirical evidence demonstrating the partial mediating role of the firm's food supply chain resilience in the nexus between food SC performance and SCP. The unique contribution of this study is an extension of the body of knowledge of SC management literature from a comprehensive approach by providing a proven set of performance measures of SC management to which it can drive SC resilience and SCP for food manufacturing SMEs in an emerging economy that hardly found in the current literature.

ABSTRACT

COVID-19 pandemic caused different levels of impact across the industries, including agriculture, since it is a food chain reaction from the raw materials to the end product. The main purpose of our review research is to find out how the Chinese government responded to food security and price in the agricultural market in post COVID19 era and then follow with key issues that need to be considered, such as steady agricultural product prices. Also, during the post COVID-19, the conflict between Russia and Ukraine affected the world's agricultural production and market. This review research concluded the strategies of the Chinese government to respond to this global issue from the point of view of agriculture. The paper also proposed some solutions and suggestions that can be applied during this new era. In the end, we concluded effective policies and regulations that have been proven by the Chinese government and can be referred to by other countries or regions.

ABSTRACT

Research by the International Food Policy Research Institute (IFPRI) on the impacts of Covid-19 regarding global food security suggests that the poor are disproportionately affected. Furthermore, the pandemic appears to have pushed more people into poverty in rural than in urban areas. Analyses also address impacts which Covid-19 has had on supply chains. This article looks at some of the findings and emphasises the role of policies in making food systems sustainable, resilient and inclusive.

ABSTRACT

This study aims to determine communication about food security during the COVID-19 Pandemic by Analyzing the Indonesian Government's official Twitter account. This research method uses the NVIVO 12 plus in analyzing data with chart, cluster, and word cloud analysis. This research's data source came from the Food Security Agency Twitter accounts and the Logistics Affairs Agency. This study chose the Food Security Agency and the Logistics Affairs Agency's Twitter social media accounts because they are responsible for Indonesia's food security. The finding of this study, the Food Security Agency is more dominant in discussing communication content related to agriculture, availability of foodstuffs, food needs, and food prices compared to the Logistics Affairs Agency. Meanwhile, the Logistics Affairs Agency is superior in communicating content about rice availability during the COVID-19 pandemic. Content is related to one another, but the most vital link is between foodstuffs and rice availability. The Food Security Agency and Logistics Affairs Agency's communication narrative with the Indonesian people during the COVID-19 pandemic concerns rice, prices, food, and Indonesian farmers. The Logistics Affairs Agency has a higher communication intensity than the Food Security Agency with the Indonesian people in early 2020 to March 2021 period. © 2021 by SCITEPRESS – Science and Technology Publications, Lda.

ABSTRACT

This article aims to understand how supermarket chains in Brasília (DF) faced the covid-19 pandemic and which strategies were used to adapt to changes in trade and consumption. The methodology of the study consisted in a selection of the ten largest supermarket chains in number of stores of the Supermarket Association of Brasília (ABRAS). At the beginning of the pandemic with the closing of free fairs and public markets, the population was compelled to consume in supermarkets. In response, retail chains have invested massively in increasing e-commerce and ominicality. It was verified in Brasilia the incentive to purchase on the websites and in own applications concomitantly with the inauguration of physical stores. Another measure was the renovation and modernization of stores with the provision of service and delivery services. The research concludes that the hybrid character of the physical and the digital demonstrates the centrality of the spatialities of consumption complexified with the advent of the pandemic opening the possibility of new research agendas whose participation in geography becomes fundamental.

ABSTRACT

The catering industry is responsible for producing and distributing meals in schools, hospitals, and companies' cafeterias. Dietary pattern changes and smart working caused by the Covid pandemic highly affect the food catering industry. The demand contraction put in crisis the typical distributed productive structure of such a sector. A 30% revenue reduction from 2019 to 2020 called for the widespread network of production plants to cut corners. Production centralization leads to economies of scale but increases the logistics costs of distribution. We present a real case study of production network downsizing in the catering industry, focusing on optimizing logistics and fixed capacity costs. Meals distribution has tight time constraints due to the consumers-imposed time windows and the microbiological safety rules-imposed time windows. The proposed methodology integrates the vehicle routing problem developed by the company into a network costs optimizations problem. This optimization model exploits the pre-optimized routes defined by the company, chooses which plants to open, and performs the customer-route pairing for each picked production site. Different allocation scenarios of the same demand distribution are defined and analyzed in the case study, allowing a quantitative comparison between different redesign strategies. Results show how the mileage varies among the centralized scenarios, with a cost differential from +61% to + 29% compared to the distributed scenario. The comparison of pre and post covid demand scenarios shows how the model cushions the logistics costs: the optimal choices of the routes allows a 22% traveling reduction in the 38% post-pandemic demand reduction of the same service area. The model supports the decision-making process in the network redesign of the food catering industry by analyzing how alternative location-allocation scenarios deal with different demand patterns. © 2022, AIDI - Italian Association of Industrial Operations Professors.

ABSTRACT

Food security, which is considered to be a public health-related socioeconomic factor, ensures the health of society's people and plays a significant role in improving governance. This concept is closely related to the concept of stability of food. The stability of food means that there should be adequate, quality, and nutritious food for all human beings, in all places and at all times, and no factor should prevent this important issue. Stability in food production and supply is at the heart of food security and makes food systems resilient in times of crisis. The negative impact of climate change on agricultural production, intensified inflationary trends, high food prices, increasing food waste, increasing the need for food imports, and, more significantly, ongoing international sanctions make it difficult to access affordable food and pose challenges to Iran's food security. Moreover, the COVID-19 crisis has reduced the incomes of families and government by intensifying economic pressures on government incomes as well as rising unemployment, which has directly exacerbated food insecurity. The link between indicators of food stability and food security in Iran is the subject of this article. The key indicators selected are the percent of arable land equipped for irrigation, the cereal imports dependency ratio, the value of food imports over total merchandise exports, per capita food production variability, and, per capita food supply variability. Results show Iran is vulnerable to the arable land equipped for irrigation, food imports over total merchandise exports, and the cereal imports dependency ratio while being resilient per capita food production and food supply variability. © 2022 Ghalibaf et al.

ABSTRACT

Food security (FS) is one of the most elusive and sought-after objectives worldwide. Securing a country's self-sufficiency - in the current COVID-19 pandemic era, more than ever - has become a prioritized mission. In the Middle East and North Africa (MENA) region, FS is adversely affected by, among others, the scarcity of freshwater, harsh environment, regional conflicts, and rising temperatures. Following the eruption of the COVID-19 pandemic, exporters placed export restrictions on key food crops, affecting FS in import dependent regions, such as the MENA countries and, more specifically, the United Arab Emirates (UAE). This paper presented a conceptual framework on the key enablers for the UAE agri-food supply chains to obtain the necessary resiliency to achieve FS, through improving policy-making capacity. The proposed approach started with the assessment of the main vulnerabilities of the food system in a global context;from there, the factors that influence vulnerability were investigated, identifying the main global drivers that affect the local food systems, focusing on the UAE. The proposed framework was applied for the design and implementation of an early warning system concerning FS-related incidents.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic, which began in 2019, has far-reaching ramifications, including economic losses and health challenges that still affect various parts of the world. During our review, we learned that the entire world is working to stop the spread of the SARS-CoV-2 outbreak. We explore ways that may lower the danger of SARS-CoV-2 contamination and useful strategies to avoid the possibility of SARS-CoV-2 spreading through food. While hygienic protocols are required in the food supply sector, cleaning, disinfection, and the avoidance of cross-contamination across food categories and other related goods at different stages of the manufacturing process remain especially important because the virus can survive for long periods of time on inert materials such as food packaging. Furthermore, personal hygiene (regular washing and disinfection), wearing gloves and using masks, garments, and footwear dedicated to maintaining hygiene provide on-site safety for food sector personnel, supply chain intermediaries, and consumers. Restrictions imposed in response to the pandemic (e.g., closure of physical workplaces, canteens, cafes, restaurants, schools, and childcare institutions), changes in household grocery shopping frequency, individuals' perceived risk of COVID-19, income losses due to the pandemic, and sociodemographic factors are among the factors. The conclusions drawn from this study consider the implications of healthy diets, food system resilience, behavior change, and nutritional imbalance for policymakers and food supply chain participants, as well as the antimicrobial effects of vitamins and nutrients. During a public health crisis, people should eat less, necessitating preventive policies and nutritional advice to deal with this.

ABSTRACT

Son yıllarda gıda fiyatlarındaki artışlar ile gıda kıtlığına yönelik sinyaller veren küresel gıda tedarik zincirlerinin kırılganlığı, COVID-19 salgını sürecinde hükümetlerin uyguladığı kapanma önlemleri ile en üst seviyeye çıkmıştır. Bu çalışmada, halen devam etmekte olan COVID-19 salgını ve salgınla mücadelede alınan önlemlerin küresel gıda tedarik zincirlerinde neden olduğu aksaklıkların ve bu aksaklıkların gıda güvencesine etkilerinin ortaya konulması amaçlanmaktadır. Gıda tedarik zincirlerindeki akışın bozulmasına neden olan arz ve talep yönlü şoklarla gıda güvencesini tehdit eden aksaklıklar, yeterli ve besleyici gıdaya erişimi salgın kadar önemli bir sorun haline getirmiştir. Gıda tedarik zincirinde;tüketicilerin panik yönlü satın alma davranışı göstermesi, işgücü piyasalarında değişime bağlı iş ve gelir kayıpları ile enflasyon talep yönlü etkiler olarak görülmüştür. Íşgücü kıtlığı, ulaşım ağlarındaki aksamalar ve ülkelerin koyduğu sınırlamalar, dijital teknolojinin imkânları ile e-ticaretin yaygınlaşması ise arz yönlü etkiler olarak ortaya çıkmıştır. COVID-19 salgını, arz ve talep yönlü şoklarla gıda güvencesi üzerinde gıdanın fiziksel bulunabilirliğini, gıdaya ekonomik ve fiziksel erişimi, gıda kullanımını ve gıda istikrarını tehlikeye atan olumsuz etkilere neden olmuştur. Çalışma sonunda, gıda güvencesini sağlamada, gıda sistemlerinin dayanıklılığı, gıda tedarik zincirlerinin otomasyonu, çalışanların güvenliği ve tedarik zinciri faaliyetlerinin çevrimiçi ortamlarda denetlenmesinin önemi, gıda güvencesizliği yaşayan savunmasız gruplara yönelik devletin sosyal güvenlik politika ve uygulamaları ile gıda egemenliği konuları tartışılmıştır.Alternate :The fragility of global food supply chains, which signals food shortages and increases in food prices in recent years, has reached the highest level with the government's lockdown measures during the COVID-19 pandemic. The study aims to highlight the disruptions in global food supply chains brought about by the ongoing COVID -19 pandemic and present the impact of these disruptions on food security. Supply-side and demand-side shocks that bring about deterioration of the flow in food supply chains and disruptions that threaten food security have made access to adequate and nutritious food an issue as significant as the pandemic. In the food supply chain, panic-oriented buying behaviors by consumers, job and income losses due to changes in labor markets and inflation have occurred as demand-side effects. Labor shortages, disruptions in transportation networks, restrictions imposed by countries, the opportunities of digital technology, and the spread of e-commerce have emerged as supply-side effects. The COVID-19 pandemic has caused negative effects on food security, jeopardizing availability, access, utilization, and stability with supply-side and demand-side shocks. In the conclusion part of the study, the resiliency of food systems, automation of food supply chains, the safety of employees and the importance of monitoring supply chain activities in online environments, the social security policies and practices of the state for vulnerable groups experiencing food insecurity, and food sovereignty were discussed.
