Food Security during the Pandemic and the Importance of the Bioeconomy in the New Era

Development of a machine vision-based weight prediction system of butterhead lettuce (Lactuca sativa L.) using deep learning models for industrial plant factory

Introduction

Indoor agriculture, especially plant factories, becomes essential because of the advantages of cultivating crops yearly to address global food shortages. Plant factories have been growing in scale as commercialized. Developing an on-site system that estimates the fresh weight of crops non-destructively for decision-making on harvest time is necessary to maximize yield and profits. However, a multi-layer growing environment with on-site workers is too confined and crowded to develop a high-performance system.This research developed a machine vision-based fresh weight estimation system to monitor crops from the transplant stage to harvest with less physical labor in an on-site industrial plant factory.

Methods

A linear motion guide with a camera rail moving in both the x-axis and y-axis directions was produced and mounted on a cultivating rack with a height under 35 cm to get consistent images of crops from the top view. Raspberry Pi4 controlled its operation to capture images automatically every hour. The fresh weight was manually measured eleven times for four months to use as the ground-truth weight of the models. The attained images were preprocessed and used to develop weight prediction models based on manual and automatic feature extraction.

Results and discussion

The performance of models was compared, and the best performance among them was the automatic feature extraction-based model using convolutional neural networks (CNN; ResNet18). The CNN-based model on automatic feature extraction from images performed much better than any other manual feature extraction-based models with 0.95 of the coefficients of determination (R2) and 8.06 g of root mean square error (RMSE). However, another multiplayer perceptron model (MLP_2) was more appropriate to be adopted on-site since it showed around nine times faster inference time than CNN with a little less R2 (0.93). Through this study, field workers in a confined indoor farming environment can measure the fresh weight of crops non-destructively and easily. In addition, it would help to decide when to harvest on the spot.

Triple-crises-induced food insecurity: systematic understanding and resilience building approaches in Africa

The triple crises of the COVID-19 pandemic, conflict and climate change have severely impacted food systems, leading to socio-economic consequences and undermining food and nutrition security across Africa. To address the malnutrition and poverty affecting approximately 700 million people in Africa, there is potential for the One Health approach implementation and operationalization to bring together multidisciplinary solutions for tackling food insecurity and ensuring food safety net. However, there is limited documentation on the potential of the One Health approach system thinking implementation to guide responses to triple crises-induced food insecurity. Therefore, this article aims to systematically understand the triple crises-induced food insecurity, connect existing solutions, and explore the role of the One Health approach in strengthening food and agriculture systems in Africa. Our finding showed the impact of triple crises exacerbating food system vulnerability in Africa and worldwide. Mitigating and resilient actions are urgently needed in tackling the emerging and persisting challenges, and infectious diseases menace and burden across Africa. We present a conceptual model illustrating the complex nature of triple crises-induced food insecurity, vulnerability areas within the food system, and actionable strategies for building community food resilience. Additionally, recommendations are provided to create an enabling environment that supports One Health approach implementation and addresses food insecurity challenges through innovative partnerships, local-led initiatives, and enhanced governance and artificial intelligence technology capacities in achieving sustainable and inclusive growth to reduce socio-economic inequalities. Stepping up integrated, actionable, and sustainable food systems programs and innovative long-lasting solutions requires investing in promoting new partnership and research collaboration in building conflict resolution and peace towards strengthening and reshaping local and global food security related climate change adaptations actions for most vulnerable communities' benefits. These are ingredients in fastening preparedness, prevention and control of infectious diseases prevention and control, reducing food supply chains disruption towards accelerating equitable benefits of Universal Health Coverage and Sustainable Development Goals, 2030 across Africa.

An Update on Effectiveness and Practicability of Plant Essential Oils in the Food Industry

Consumer awareness and demands for quality eco-friendly food products have made scientists determined to concentrate their attention on sustainable advancements in the utilization of bioactive compounds for increasing safety and food quality. Essential oils (EOs) are extracted from plants and exhibit antimicrobial (antibacterial and antifungal) activity; thus, they are used in food products to prolong the shelf-life of foods by limiting the growth or survival of microorganisms. In vitro studies have shown that EOs are effective against foodborne bacteria, such as Escherichia coli, Listeria monocytogenes, Salmonella spp., and Staphylococcus aureus. The growing interest in essential oils and their constituents as alternatives to synthetic preservatives has been extensively exploited in recent years, along with techniques to facilitate the implementation of their application in the food industry. This paper’s aim is to evaluate the current knowledge on the applicability of EOs in food preservation, and how this method generally affects technological properties and consumers’ perceptions. Moreover, essential aspects concerning the limitation of the available alternatives are highlighted, followed by a presentation of the most promising trends to streamline the EOs’ usability. Incorporating EOs in packaging materials is the next step for green and sustainable foodstuff production and a biodegradable method for food preservation.

Evaluating the regional risks to food availability and access from land-based climate policies in an integrated assessment model

Mitigating greenhouse gas emissions is necessary to reduce the overall negative climate change impacts on crop yields and agricultural production. However, certain mitigation measures may generate unintended consequences to food availability and food access due to both land use competition and economic burden of mitigation. Integrated assessment models (IAM) are generally used to evaluate these policies; however, currently these models may not capture the importance of income and food prices for hunger and overall economic wellbeing. Here, we implement a measure of food security that captures the nutritional and economic aspects as the total expenditures on staple foods divided by income and weighted by total caloric consumption in an IAM, the global change analysis model (GCAM4.0). We then project consumer prices and our measure of food security along the shared socioeconomic pathways. Sustained economic growth underpins increases in caloric consumption and lowering expenditures on staple foods. Strict conservation policies affect food accessibility in a larger number of developing countries, whereas the negative effects of pricing terrestrial emissions are more concentrated on the poor in Sub-Saharan Africa, by substantially replacing their cropland with forests and affecting the production of key staples.

Working through Disaster Risk Management to Support Regional Food Resilience: A Case Study in North-Eastern Australia

As a consequence of disasters such as pandemics and severe weather events, Australian communities often face ‘food shortages’ resulting from the reduced availability of food and reduced access to available food. These food shortages can be acutely felt by vulnerable populations, comprising people in communities who are already dealing with social or economic disadvantages. Despite growing calls to ensure food access for everyone during and following disasters, efforts are still largely ad hoc, champion based and highly variable in their reliability and quality of supply. There is also a disconnect between disaster-related food relief and improving business continuity towards local economic resilience. This study sought to tackle these challenges by exploring how ‘local food access’ could be integrated within disaster management mechanisms, to support the most vulnerable and also contribute to local economic resilience. This paper discusses the findings of a study undertaken in Cairns, a north-eastern Australian regional authority, and involves a review of disaster management planning and policy artifacts, an online survey, and semi-structured interviews with stakeholders providing care and advocacy for vulnerable populations. Synthesizing the findings, we present a disaster-management-focused ‘Local Food Access Model’ that connects shorter food supply chains to improved disaster response, resilience and contingency-planning agendas. Applying this model to Cairns, we conclude the multiple benefits and immediate stakeholder readiness for a virtual (online) food resilience and contingency hub, to enable the connection of local food availability and access information within existing disaster management processes. The research method used, the model, and the case-specific findings provide government decision makers with a useful process, a local food-access schematic and a case study example to support immediate improvements in disaster resilience for vulnerable populations.

Reintegration of Brewers Spent Grains in the Food Chain: Nutritional, Functional and Sensorial Aspects

Nowadays, the pandemic situation has encouraged the idea of sustainable healthy foods leading to new trends in food consumption. Brewers spent grain (BSG) represents a potential functional food rich in fiber, protein, lipids, mineral and phenols that needs to be further exploited. In this vein, five different BSG types were collected from local breweries and valorized in cookies manufacturing. Thus, proximate composition (protein, minerals, lipids, ash, crude fiber and carbohydrates) was analyzed using AACC (American Association of Cereal Chemists) methods, DPPH (2,2-Diphenyl-1-picrylhydrazyl), and Folin Ciocalteu methods were used to determined antioxidant activity and total phenols, while minerals and aroma volatile compounds were performed using inductively coupled plasma optical emission spectrometry (ICP-OES) and ITEX/GC-MS (in tube extraction gas chromatography-mass spectrometry) respectively. Color and physical characteristics, together with sensorial analysis, were also evaluated. The results highlighted a significant difference between BSG samples, mainly from the total phenols, antioxidant activity and aroma volatile compounds point of view. BSG volatiles compounds from the aldehydes group such as 2-methyl-propanal, 3-methyl-butanal and 2-methyl-butanal were identified also in the final baked goods, leading to a pleasant and appreciated consumers' taste and aroma. Furthermore, cookies sensorial analysis emphasized that the sample manufactured with BSG from light and dark malt mixture was more appreciated by consumers, attaining the highest hedonic scores.

Effects of the COVID-19 Pandemic on Food Security and Agriculture in Iran: A Survey

The consequences of COVID-19 on the economy and agriculture have raised many concerns about global food security, especially in developing countries. Given that food security is a critical component that is affected by global crises, beside the limited studies carried out on the macro-impacts of COVID-19 on food security in Iran, this paper is an attempt to address the dynamic impacts of COVID-19 on food security along with economic and environmental challenges in Iran. For this purpose, a survey was conducted with the hypothesis that COVID-19 has not affected food security in Iran. To address this fundamental hypothesis, we applied the systematic review method to obtain the evidence. Various evidences, including indices and statistics, were collected from national databases, scientific reports, field observations, and interviews. Preliminary results revealed that COVID-19 exerts its effects on the economy, agriculture, and food security of Iran through six major mechanisms, corresponding to a 30% decrease in the purchasing power parity in 2020 beside a significant increase in food prices compared to 2019. On the other hand, the expanding environmental constraints in Iran reduce the capacity of the agricultural sector to play a crucial role in the economy and ensure food security, and in this regard, COVID-19 forces the national programs and budget to combat rising ecological limitations. Accordingly, our study rejects the hypothesis that COVID-19 has not affected food security in Iran.

Qualitative Research on Solving Difficulties in Maintaining Continuity of Food Supply Chain on the Meat Market during the COVID-19 Pandemic

Although the pandemic phenomenon is not the first of its kind in human history, the common feature of COVID-19 is its rapid impact on the global economy. The challenge for the national economy on the world stage is to maintain a continuous food supply. The scientific purpose of the study is to report, analyze and evaluate backgrounds, causes of instabilities and their effects of the COVID-19 pandemic on supply and demand side of the meat market in the United States of America, China and Russia. The practical purpose of the study is to present implemented measures and recommendations on how to return to meat market equilibrium. In the theoretical part of the study, the revised public source of information coming from well-known organizations such as: EC, FAO, OECD, and WB, are used. In the practical part of the manuscript, qualitative research on the People’s Republic of China, Russian Federation, and the United States of America, along with semi-structured in-depth interviews with experts and Ishikawa diagram are presented. The primary data come from authors’ own research and collection of multiple sources. The article indicates the use of qualitative systematic review, supported by a creation of a prototype of the issues of maintaining continuity of the food supply chain during the COVID-19 pandemic in the secondary sources, intensified by a keyword search. The results of the research are diverse and oriented toward the needs of the analyzed meat markets. In the case of the People’s Republic of China, the solution is to develop a system of subsidies and preferential rates for the use of rail transport in exports. In the case of Russia, the solution is to provide support to the meat and poultry farmers for cold storage of slaughtered animals. In the case of the USA, the solution is to develop technical and technological facilities in order to speed up the supply chain between local livestock with meat and poultry farmers. Moreover, the outcomes indicate that sustainability of the food supply chain needs well-thought-out support on agri-food supply production.

COVID-19, poverty and inclusive development

The COVID-19 epidemic provides yet another reason to prioritize inclusive development. Current response strategies of the global community and countries expose a low level of solidarity with poorer nations and poorer people in all nations. Against this background, this paper addresses the question: What are the development challenges that the COVID-19 pandemic lays bare and what lessons can be learnt for the way recovery processes are designed? Using an inclusive development and DPSIR lens to assess the literature, our study finds that, first, the current response prioritises the 'state' and 'impact' concerns of wealthier classes at the expense of the remainder of the world population. Second, responses have ignored underlying 'drivers' and 'pressures', instead aiming at a quick recovery of the economy. Third, a return to business-as-usual using government funding will lead to a vicious cycle of further ecological degradation, socio-economic inequality and domestic abuse that assist in exacerbating the drivers of the pandemic. We argue instead for an inclusive development approach that leads to a virtuous cycle by emphasizing human health, well-being and ecosystem regeneration. We conclude that the lost years for development did not commence in 2020 with the onset of COVID-19; the downward trend has actually been waxing over the past three decades. From this perspective, COVID-19 may be the shock needed to put the last first and transform vicious into virtuous cycles of inclusive development.

Causal Impacts of Epidemics and Pandemics on Food Supply Chains: A Systematic Review

The epidemics and pandemics can severely affect food supply chains, including producers, retailers, wholesalers, and customers. To minimize their impacts, it is fundamental to implement effective policies that ensure continuity in the provision, affordability, and distribution of basic food items. This research identifies the main impacts of pandemics and epidemics on food supply chains and policies that can minimize these impacts. Based on a systematic literature review (SLR), 173 documents are analysed to propose a taxonomy of impacts on four supply chain links: demand-side, supply-side, logistics and infrastructure, and management and operation. The taxonomy presents the main impacts and respective mitigation policies. In addition, the literature review leads to the development of a comprehensive causal loop diagram (CLD) with the identification of main variables and their relationship with food supply chains. Finally, a specific research agenda is proposed by identifying the main research gaps. These findings provide a structured method for evaluating policies that ensure the functioning of food supply chains, particularly in disruptions such as epidemics and pandemics.

The increasing hunger concern and current need in the development of sustainable food security in the developing countries

Background

COVID-19 has affected millions of people worldwide. Recently, international agencies have revealed that poverty and hunger could kill more people than COVID-19 victims. Many global workforces have lost their jobs during this pandemic situation. In developing countries, most of the workers and their families live hand to mouth, depending on daily wage, and loss of income would be a hunger pandemic. Globally, the proportion of undernourished and hungry people have been on an upswing due to climate changes and violent conflicts. The millions of people are facing chronic malnourishment and COVID-19 menaces undermining the endeavour of philanthropic and food security. COVID-19 has increased the risk of livelihood by the shortage of food and distraction of the supply chain especially in the developing countries where rural expanses depend on agriculture production and seasonal jobs. So, if they are forced to limit their activities, their livelihoods will be demolished.

Scope and approach

COVID-19 is increasing the jeopardy of food prices over the world, which would prompt a crisis in several developing countries. The government organizations in developing countries are doing well to protect people from the current pandemic. But they are also in critical situation regarding food supply chains and are facing difficulties in providing nutrient-rich foods. The susceptible people are fraught to secure household income and manage their food. In this review, we have explored the food security approach, food supply chain and risk of food shortage. Every country in the world needs to implement effective interventions to maintain open trade and food supply chains, ensure access to nutrients for all at affordable prices and develop co-operation to preserve the flexibility of universal food markets.

Dietary Fiber and Prebiotic Compounds in Fruits and Vegetables Food Waste

The fruits and vegetables processing industry is one of the most relevant food by-products, displaying limited commercial exploitation entailing economic and environmental problems. However, these by-products present a considerable amount of dietary fiber and prebiotics with important biological activities, such as gut microbiota modulation, lowering the glycemic load and replacing some unhealthy ingredients with an impact on food texture. Therefore, the international scientific community has considered incorporating their extracts or powders to preserve or fortify food products an area of interest, mainly because nowadays consumers demand the production of safer and health-promoting foods. In the present review, literature, mainly from the last 5 years, is critically analyzed and presented. A particular focus is given to utilizing the extracted dietary fibers in different food products and their impact on their characteristics. Safety issues regarding fruits and vegetables wastes utilization and anti-nutritional compounds impact were also discussed.

COVID-19 and Policy Impacts on the Bangladeshi Rice Market and Food Security

This research employs a partial equilibrium model to estimate the short- and long-run effects of COVID-19 and rice policies on Bangladesh’s rice market and food security. We also analyze the impact of relevant policies in terms of their effectiveness in mitigating stresses stemming from a hypothetical pandemic with a COVID-19-like impact. The results indicate that the effect of COVID-19 on Bangladeshi food security during FY 2019/20 was mixed, as the indicators of food availability improved by 5%, and decreased by 17% for food stability, relative to what they would have been otherwise. Policy simulation results indicate that a higher import tariff improves self-sufficiency status, but undermines rice availability and accessibility by bending the market toward a restrictive trade regime. Results also indicate that unlike stock enhancement policy, closing the existing yield gap improves rice availability, accessibility, and moderates the depressing effect of a future event with repercussions similar to COVID-19, although the yield policy appears more speculative and could be too costly. The insights generated contribute to the understanding of policies that aim to achieve sustainable development goals related to aggregate food security, and build resilience against future shocks akin to COVID-19.

Innovations and technology disruptions in the food sector within the COVID-19 pandemic and post-lockdown era

Background

COVID-19 pandemic has caused a global lockdown that has abruptly shut down core businesses and caused a worldwide recession. The forecast for a smooth transition for the agri-food and drink industry is, at best, alarming. Given that COVID-19 shutdown multiple core services (such as aviation, food services, supply chains, and export and import markets), there is an enormous deficiency in critical information to inform priority decision making for companies where this uncertainly is likely to impact negatively upon recovery.

Scope and approach

The current article investigates potential innovations within the era of the COVID-19 crisis after framing them within the four issues of the food sector (food safety, bioactive food compounds, food security, and sustainability) that are directly affected by the pandemic. The prospect of foreseen innovations to disrupt the food sector during lockdown periods and the post-COVID-19 era is also discussed.

Key findings and conclusions

Internet and Communication Technologies, blockchain in the food supply chain and other Industry 4.0 applications, as well as approaches that redefine the way we consume food (e.g., lab-grown meat, plant-based alternatives of meat, and valorization of a vast range of bioresources), are the innovations with the highest potential in the new era. There is also an equally pressing need to exploit social marketing to understand attitudes, perceptions, and barriers that influence the behavior change of consumers and the agri-food industry. Subsequently, this change will contribute to adapting to new norms forged by the COVID-19 pandemic, where there is a significant gap in knowledge for decision making.

Awareness and Performance towards Proper Use of Disinfectants to Prevent COVID-19: The Case of Iran

This study aimed to assess the awareness and performance of Qom citizens towards using disinfectants and compared its relationship with geographical distribution of COVID-19 outbreak in Qom, Iran. The study was conducted by a researcher-made questionnaire during April and May, 2020. COVID-19 incidence data for each district of city was obtained from health department of Qom province. Data were analyzed using Excel, SPSS and ArcView (GIS) softwares. It was found that the highest level of citizens' awareness (52%) was in the weak range while their performance (56%) was in the good range. According to Spearman's correlation analysis, there was a strong correlation (rho 0.95) between the total mean of awareness and performance (p < 0.01). The highest incidence rate of COVID-19 was in district 7 which had the lowest mean score in both awareness and performance. In addition, the results of ANOVA (LSD-least significant difference) showed that there was a significant difference (p < 0.05) between district 7-with lower mean scores in awareness and performance-and other districts. Overall, it is concluded that citizens' awareness level was lower than that of their performance. This conclusion not only calls for more training programs to be implemented in public places, schools, universities and governmental offices, but it also necessitates maintaining a proper and timely training about using disinfectants.
