Salinization of soils and freshwater resources by natural processes and/or human activities has become an increasing issue that affects environmental services and socioeconomic relations. In addition, salinization jeopardizes agroecosystems, inducing salt stress in most cultivated plants (nutrient deficiency, pH and oxidative stress, biomass reduction), and directly affects the quality and quantity of food production. Depending on the type of salt/stress (alkaline or pH-neutral), specific approaches and solutions should be applied to ameliorate the situation on-site. Various agro-hydrotechnical (soil and water conservation, reduced tillage, mulching, rainwater harvesting, irrigation and drainage, control of seawater intrusion), biological (agroforestry, multi-cropping, cultivation of salt-resistant species, bacterial inoculation, promotion of mycorrhiza, grafting with salt-resistant rootstocks), chemical (application of organic and mineral amendments, phytohormones), bio-ecological (breeding, desalination, application of nano-based products, seed biopriming), and/or institutional solutions (salinity monitoring, integrated national and regional strategies) are very effective against salinity/salt stress and numerous other constraints. Advances in computer science (artificial intelligence, machine learning) provide rapid predictions of salinization processes from the field to the global scale, under numerous scenarios, including climate change. Thus, these results represent a comprehensive outcome and tool for a multidisciplinary approach to protect and control salinization, minimizing damages caused by salt stress.

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.

Analyses of statistical data were made and their results discussed in this article to identify the level of Poland’s energy security and to determine the role of agriculture in ensuring it. It has been demonstrated that coal continues to be the staple resource for the generation of energy in Poland. The current demands and requirements concerning the reduced consumption of non-renewable resources and Poland’s obligations towards the European Union regarding the production of energy from renewable resources—all these considerations contribute to the promotion of a skillful development of energy crop farming, which, in Poland, is likely to be very successful. Agriculture plays an important role in ensuring Poland’s energy security, and this branch of farming can grow dynamically provided adequate legal regulations and promotion are in place. The chief resource for renewable energy generation is biomass. Straw and biogas production in agricultural biogas plants are two solutions whose full energy production potential still awaits to be tapped.

The issue of environmental management systems in food processing companies is gaining importance due to the need to reduce water withdrawal, wastewater, air emissions, and waste generation. New technological solutions and innovations can reduce the negative effects of the enterprises’ production facilities on the environment. In Poland, the phenomenon of increasing use of the amount of renewable energy sources is influenced by, e.g., adopted national and EU legislation, development of new technologies in the field of energy, and increasing awareness of producers and consumers in the field of ecology and environmental protection. It is also important that the state creates favorable conditions for the use of renewable energy in micro-installations. The application goal of the study is to develop a procedure for improvement of the environmental management systems for food processing companies and increase the awareness of potential use and implementation of renewable energy sources by food processing entities. In the theoretical part of the study, methods of comparative, deductive, and synthetic analysis are used. In the practical part of the study survey method, case studies, a simple flashback, and transfer of ideas are presented. The results of the research can be used by state institutions to put emphasis on the implementation of sustainable development of state policy on the food market.

The issue of the efficiency of food processing enterprises is ever-present because of the continuous process of improving the quality standards of raw materials, complying with the procedures in food production, introducing modern production technology, and, above all, due to the large number of actors who are competing for customers in the domestic and foreign food market. In the coming years, the Polish food processing sector will be facing significant challenges with the inevitable slow and gradual decrease in the cost advantages of raw material prices as well as ready-to-eat products. Manufacturing businesses, in the long run, will need to determine the efficiency, and hence the competitiveness of the Polish food processing sector. The aim of this paper was to review the domestic and foreign literature in terms of the classification and systematization of the concept of eco-efficiency and to find the most optimal set of eco-efficiency measures based on the research in chosen food processing enterprises in Poland. In the theoretical part of the study, methods of descriptive, comparative, deductive, and synthetic analysis were used. In the practical part of the study, appropriately selected qualitative methods, such as a questionnaire, were presented. The results of the analysis were based on the results of the authors’ own calculations, as well specific findings from business practice, both from inland and abroad.
