“…During 2019-2021, Ukraine accounted for 10% of global wheat exports, about 50% of sunflower oil exports, and 15% of barley and corn exports. These indicators confirm the existence of a threat to global food security, which is also noted by the authors of the article [4], who tried to analyze the potential impact of military aggression against Ukraine on food production.…”

The conceptual foundations of monitoring the state’s food security system under the conditions of global turbulence have been deepened. It was determined that the set of indicators of the state of food security used in national practice is imperfect. It is emphasized that the totality of indicators cannot objectively contribute to identifying potential threats to sustainable development and adopting effective management decisions. Attention is focused on the need to consider the impact of other components, including the issues of the accessibility, availability, quality, and safety of food products, as well as their resilience and adaptability. The hypothesis regarding the direct relationship between the degree of compliance of agricultural production in the country with sustainable development principles and the overall level of economic accessibility of food has been proved. The established and mathematically proven direct relationship between the indicators made it possible to emphasize the need to raise the population’s living standards. This is necessary to reduce the negative impact of the production of agricultural products on the environment, which results from the understanding by consumers of the need to satisfy not only basic needs but also to preserve natural resources for future generations. It is mathematically proven that in countries with a high level of economic accessibility of food, the compliance of agricultural production with sustainable development principles has a high level and is strongly correlated with economic factors. In countries with medium and low indicators of economic accessibility of food, such a relationship does not have statistical significance. The conclusions drawn are useful for practical use in conditions of global economic turbulence.

“…The role of international aid and assistance to these affected countries, as well as to Ukraine itself, is paramount in ensuring their food security. Some of the impacts already felt in the food system include rising agricultural prices, declining trade volumes and severe food insecurity (Feng et al, 2023). The vegetable oil price index more than doubled, the cereal price index increased by more than 60% and the sugar price index by more than 50% (FAO, 2023).…”

SummaryThis article explores the impact of the ‘Quadruple Whammy’ consisting of Brexit, COVID‐19, Conflicts (Russia‐Ukraine and Israel‐Palestine) and Natural disasters on the food supply chain in Europe. This research adopted a two‐phase methodology comprised of the e‐Delphi technique followed by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‐Analyses) approach within the context of these four identified challenges. The objective of this article is to analyse the challenges faced by the European food supply chain due to these four factors. The article examines the impact of political isolationism such as Brexit on trade, cost and border controls, while also discussing the effects of COVID‐19 on labour, supply chains and the rise of e‐commerce. In addition, the article examines the impact of conflicts on food access and availability and the role of international aid and assistance. The effects of natural disasters, such as the Turkish and Moroccan earthquakes, floods in Spain and Portugal and the Moroccan drought, on food security are also analysed. The article offers several strategies for taming the quadruple whammy, such as investing in local food production and supply chains, diversifying supply chains and trade partnerships and strengthening food safety regulations and standards. The importance of building resilience and preparedness in the face of these challenges is emphasised and the article concludes with final thoughts and recommendations.

“…Just and Echaust (2022) and Fang and Shao (2022) explore risk spillovers and volatility risks in global agricultural markets during the ongoing Russia-Ukraine conflict, and their findings demonstrate a substantial increase in uncertainty and volatility in global food markets. Feng et al (2023) employ a structural general equilibrium trade framework to quantify the possible negative effects of the conflict on food production, food prices, food trade, and food security. Zhou et al (2023) develop an underload cascading failure model and a new simulation approach to identify the magnitude and process of the impact of the Russia-Ukraine conflict on global food security.…”

Ultra-dense networks are widely regarded as a promising solution to explosively growing applications of Internet-of-Things (IoT) mobile devices (IMDs). However, complicated and severe interferences need to be tackled properly in such networks. To this end, both orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) are utilized at first. Then, in order to attain a goal of green and secure computation offloading, under the proportional allocation of computational resources and the constraints of latency and security cost, joint device association, channel selection, security service assignment, power control and computation offloading are done for minimizing the overall energy consumed by all IMDs. It is noteworthy that multi-step computation offloading is concentrated to balance the network loads and utilize computing resources fully. Since the finally formulated problem is in a nonlinear mixed-integer form, it may be very difficult to find its closed-form solution. To solve it, an improved whale optimization algorithm (IWOA) is designed. As for this algorithm, the convergence, computational complexity and parallel implementation are analyzed in detail. Simulation results show that the designed algorithm may achieve lower energy consumption than other existing algorithms under the constraints of latency and security cost.
