Abstract Farmers, food supply-chain entities, and policymakers need a simple but robust indicator to demonstrate progress toward reducing nitrogen pollution associated with food production. We show that nitrogen balance—the difference between nitrogen inputs and nitrogen outputs in an agricultural production system—is a robust measure of nitrogen losses that is simple to calculate, easily understood, and based on readily available farm data. Nitrogen balance provides farmers with a means of demonstrating to an increasingly concerned public that they are succeeding in reducing nitrogen losses while also improving the overall sustainability of their farming operation. Likewise, supply-chain companies and policymakers can use nitrogen balance to track progress toward sustainability goals. We describe the value of nitrogen balance in translating environmental targets into actionable goals for farmers and illustrate the potential roles of science, policy, and agricultural support networks in helping farmers achieve them.

This paper provides a review of an emerging field in the food processing sector, referring to efficient and safe food supply chains, ’from farm to fork’, as enabled by Artificial Intelligence (AI). The field is of great significance from economic, food safety and public health points of views. The paper focuses on effective food production, food maintenance energy management and food retail packaging labeling control, using recent advances in machine learning. Appropriate deep neural architectures are adopted and used for this purpose, including Fully Convolutional Networks, Long Short-Term Memories and Recurrent Neural Networks, Auto-Encoders and Attention mechanisms, Latent Variable extraction and clustering, as well as Domain Adaptation. Three experimental studies are presented, illustrating the ability of these AI methodologies to produce state-of-the-art performance in the whole food supply chain. In particular, these concern: (i) predicting plant growth and tomato yield in greenhouses, thus matching food production to market needs and reducing food waste or food unavailability; (ii) optimizing energy consumption across large networks of food retail refrigeration systems, through optimal selection of systems that can be shut-down and through prediction of the respective food de-freezing times, during peaks of power demand load; (iii) optical recognition and verification of food consumption expiry date in automatic inspection of retail packaged food, thus ensuring safety of food and people’s health.

The nitrogen balance made on a national, regional and/or farm basis provides valuable information about the surplus of nitrogen in agricultural production. This surplus of nitrogen is dispersed into the environment, causing water pollution with nitrate and other compounds of nitrogen, air pollution with ammonia and nitrous oxide. The nitrogen balance in Polish agriculture has undergone vast changes during the last few years, according to economic and social transformations after the collapse of the communist system. The surplus of nitrogen decreased from about 90 kg N/ha in 1989 to about 60 kg N/ha in 1991. More than 30% of nitrogen surplus is volatilized into the atmosphere in the form of ammonia, while similar amounts find their way into the water, particularly groundwater. The amounts of nitrogen losses due to denitrification are difficult to estimate.

Coronavirus had been in existence for many years, but its effects has not been so evident as the whole world experienced recently. It represents an unprecedented emergency and grave societal threat. The better way to cure the emergence disease is by protecting public health. However, governments, policy makers and the international community must quickly need to act, recognize and attempt to mitigate the negative impacts (current and potential) of the pandemic and related response efforts on key sectors that contribute to food security, nutrition and livelihoods. The livestock sector is a key contributor to these areas, especially for the world's most vulnerable populations. In the light of recent challenges in food supply chain, there is now considerable concern about the food production, processing, distribution, and demand. COVID-19 resulted in the movement restrictions of workers, changes in demand of consumers, closure of food production facilities, restricted food trade policies and financial pressures in food supply chain. The effects of COVID-19 on the livestock sector are still largely unquantified and yet to be fully felt. Formal assessments have not yet been possible, but current observations reveal disruptions to livestock value chains. Lessons from past epidemics indicate these disruptions are likely to grow, along with their dire, socio- economic consequences. Moreover, considering the doubt on how these factors will play out in various areas affected especially meat processing and distribution in the years to come from the bulk of discussion in this review.     Le coronavirus existait depuis de nombreuses années, mais ses effets n'ont pas été aussi évidents que le monde entier l'a récemment expérimenté. Cela représente une urgence sans précédent et une grave menace pour la société. La meilleure façon de guérir la maladie émergente est de protéger la santé publique. Cependant, les gouvernements, les décideurs et la communauté internationale doivent rapidement agir, reconnaître et tenter d'atténuer les impacts négatifs (actuels et potentiels) de la pandémie et des efforts de riposte connexes sur les secteurs clés qui contribuent à la sécurité alimentaire, à la nutrition et aux moyens de subsistance. Le secteur de l'élevage est un contributeur clé dans ces domaines, en particulier pour les populations les plus vulnérables du monde. À la lumière des défis récents de la chaîne d'approvisionnement alimentaire, la production, la transformation, la distribution et la demande des aliments suscitent désormais des i nquiétudes considérables. Le COVID-19 a entraîné des restrictions de mouvement des travailleurs, des changements dans la demande des consommateurs, la fermeture des installations de production alimentaire, des politiques commerciales restreintes et des pressions financières dans la chaîne d'approvisionnement alimentaire. Les effets du COVID-19 sur le secteur du bétail sont encore largement non quantifiés et ne sont pas encore pleinement ressentis. Les évaluations formelles n'ont pas encore été possibles, mais les observations actuelles révèlent des perturbations dans les chaînes de valeur de l'élevage. Les leçons des épidémies passées indiquent que ces perturbations sont susceptibles de se développer, ainsi que leurs conséquences socio- économiques désastreuses. De plus, la prise en compte du doute sur la manière dont ces facteurs joueront dans divers domaines touchés, en particulier la transformation et la distribution de la viande dans les années à venir, constitue l'essentiel de la discussion dans cette revue.

Humankind has faced various pandemics in history. The food supply chain is one of the foremost vital sectors of the economy, and COVID-19 has had a clear bearing on it from the field to the consumer. In the light of recent challenges in the food supply chain, there is currently considerable concern regarding food production, processing, distribution, and demand. COVID-19 resulted in the movement restrictions of staff, changes in the demands of consumers, closure of food production facilities, restrictive food trade policies, and monetary pressures in the food supply chain.  This study describes the impact of the COVID-19 health crisis on people’s interests, opinions, and behaviour towards food. Additionally, an online questionnaire (Spanish population, n = 232) studied the changes in food shopping habits during the pandemic. To try to cover the whole Léon territory and reach the greatest number of persons through mobile phones, tablets, and computers, the questionnaire was created using the Google Forms tool and distributed using instant messaging apps such as WhatsApp, social media such as Facebook and Twitter, social networking sites such as LinkedIn and ResearchGate, and email through snowball sampling. The statistical analysis was carried out under the SPSS programme. The results are presented in the form of means and distributions. The differences between subgroups have been evaluated using student’s t-test. The level of statistical significance used in all cases was p < 0.05. This study is focused on evaluating changes in food consumption habits of the Spanish adult population throughout the COVID-19 lockdown. The study is supported by a web-based survey targeting the adult general population. From this study, we are able to conclude that the studied Spanish adult population is extremely close to from having good healthy dietary habits, considering the Mediterranean Diet as a reference of healthy uptake. An improvement of dietary behaviours throughout the COVID-19 confinement has been discovered. Health-related food selections involved increased intake of fruits, vegetables, and legumes and decreased intake of red meat, alcohol, fried foods, or pastries compared to their pre-pandemic habits.

Abstract A pandemic is not a new event encountered in the history of humanity because mankind has faced various pandemics in history. The common point of pandemics is their serious negative effects on the global economy. Considering the food supply chain, one of the most important sectors of the economy, it has been seen that COVID-19 has an impact on the whole process from the field to the consumer. In the light of recent challenges in food supply chain, there is now considerable concern about food production, processing, distribution, and demand. COVID-19 resulted in the movement restrictions of workers, changes in demand of consumers, closure of food production facilities, restricted food trade policies, and financial pressures in food supply chain. Therefore, governments should facilitate the movement of workers and agri-food products. In addition, small farmers or vulnerable people should be supported financially. Facilities should change the working conditions and maintain the health and safety of employees by altering safety measures. Food protectionist policies should be avoided to prevent an increase in food prices. In conclusion, each country must realize the severity of the situation and sometimes should tighten or loosen the measures according to the spread of the pandemic. The supply chain also should be flexible enough to respond to the challenges in the food supply chain. The purpose of this review is to evaluate the impact of COVID-19 on the agriculture and food sector and to summarize the recommendations required to reduce and control the effect of the pandemic.

Agro-food supply chain integration (ASCI) plays a growingly important role in the stable and sustainable development of agriculture. However, it is challenging for core firms to integrate the small-scale and scatted farmers due to complex transaction processes and volatile relationships in China. Agricultural co-operatives are organizations that unite farmers’ power and help them achieve economic benefits. Our research focuses on ASCI from the perspective of co-operatives. A comprehensive cooperative framework, including trinity co-operatives and trinity federations, is conducted to figure out the position and process of agricultural co-operatives in ASCI, while QCA provides detailed collaborative patterns for agricultural co-operatives to adopt. Results show that agricultural co-operatives can achieve high economic and social/environmental performance when participating in ASCI. This study further completes the ASCI literature and offers many managerial and academic implications to co-operatives’ members and policy-makers.

Abstract Nanoscience and nanotechnology are new frontiers for this century. Nanotechnology translates into the ability to manipulate the material on a nanoscale. As in other sectors, recent developments in the field of nanoscience and nanotechnology offer new opportunities for innovation for food. Nanofoods are considered foods grown, produced, processed or packaged using nanotechnological tools that incorporate nanomaterials to improve nutritional quality, taste or texture, and increase the shelf life of food. Nanotechnology’s applications are diverse, going from nanoencapsulated ingredients, such as bioactive compounds, nutrients and food additives that increase the bioavailability of the compounds, to ingredients that constitute nanostructures and nanotextures that provide barriers for physical-chemical protection, which allow modification of flavour and odour. Also, has the potential to be used as biosensors to monitor food conditions during storage and transport, through packaging that includes indicators. This review covers the development and use of nanotechnology along the food supply chain, focusing the agricultural production, industrial processing and protection through packaging, as well as addressing the advantages and disadvantages of using this technology.

The outbreak of COVID-19 has brought about another age on world as the human civilization is restricted in many aspects of everyday lives. There is no exception in the sector of food production and the supply chain of food. Due to constraints on demand, shutting of food production facilities, financial limitations, enterprise operations and delivery of different food items have been interrupted in the food supply chain. Every nation must comprehend the importance of the situation according to the spreading scenario of the ongoing pandemic. The probability of transmission via the food sector is regarded inconsequential, and the public authorities do not believe it necessary to follow COVID into workplaces. The unfavourable effects on the climate, the food framework and the people of the foodstuffs network are evident. An installation for the food supply chain should focus on amenities such as maintaining the safety and health of employees and changing working circumstances. This paper aims at discussing the effects of COVID-19 on the socio-economic status of human being including the negative impacts on the agriculture and food supply chain.
