The connection between sugar and ethanol prices is in line with concerns about the connection between oil and food prices. This paper studies the nexus between Colombia’s ethanol and sugar prices and the role that weather shocks play. Data on production and prices from the sugar mills and climate data on precipitation and temperature are used to estimate two ways to capture the relationship between prices and the role of weather shocks. First, a reduced-form estimation is made, where the study finds evidence of the pass-through of the international price to domestic prices and how high precipitation and temperature shocks increase prices. Then, the study addresses potential simultaneity problems between prices and estimates a VEC model with exogenous variables such as weather shocks. Results show that all domestic prices are affected by the international price, and the international price is affected by the white sugar domestic prices. Additionally, sugar prices react to shocks in ethanol prices, but ethanol prices do not react to shocks in sugar prices. Finally, weather shocks affect sugar prices, with daytime temperature shocks being the most damaging. Full article

Rising population, combined with declining home food production, in Arab nations has resulted in increased food imports that intensifies their dependence on international markets for vital food supplies. These nations face challenges in achieving food security because crude oil price volatility creates difficulties in managing the expenses of imported food products. This research calculates the income and price elasticities of imported food demand to understand consumer behavior changes in response to income and price variations, which helps to explain their impact on regional food security. To our knowledge, this research presents the first analysis of imported food consumption patterns across Arab countries according to their income brackets. This study employs the static Almost Ideal Demand System model to examine food import data spanning from 1961 to 2020. The majority of imported food categories demonstrate inelastic price and income demand, which means that their essential food consumption remains stable despite cost fluctuations. The need for imports makes Arab nations vulnerable to external price changes, which endangers their food security. This research demonstrates why governments must implement policies through subsidies and taxation to reduce price volatility risks while ensuring food stability, which will lead to sustained food security for these nations.

There is a strong connection between the Federal Reserve’s monetary policy and the trend of international food prices. Employing the average information share model, EGARCH(Exponential Generalized Autoregressive Conditional Heteroskedasticity), and DCC-MGARCH(Dynamic Conditional Correlation-Multivariate Generalized Autoregressive Conditional Heteroskedasticity) models, this study investigates the relationship between the U.S. dollar index, international grain futures prices, and spot prices in the context of Federal Reserve monetary policy adjustments from 2000 to 2023. The findings reveal that, first, under conditions of long-run cointegration, the U.S. dollar index exerts a strong pricing influence over international grain futures, while grain futures demonstrate a significant price discovery function over spot prices. Second, both international grain futures and spot markets exhibit asymmetric volatility, with price increases being more pronounced than decreases in response to external shocks. Additionally, the U.S. dollar index has a unidirectional and inverse influence on grain futures prices, while futures and spot prices interact bidirectionally and move in the same direction. This paper contributes to understanding the impact of Federal Reserve monetary policy adjustments on international food prices and offers policy insights for countries to manage food import risks and maintain price stability.

Maritime transport carries over 80% of global trade by volume and remains the most energy-efficient mode for long-distance goods movement. However, the sector contributes approximately 3% of global Greenhouse Gas (GHG) emissions, a share that could rise to 17% by 2050 without effective regulation. In response, the International Maritime Organization (IMO) has introduced initial and short-term measures to enhance energy efficiency and reduce emissions. In 2023, IMO Strategy expanded on these efforts with medium-term measures, including Market-Based Mechanisms (MBMs) such as a GHG levy, a feebate system, and fuel intensity regulations combined with carbon pricing. This study evaluates the economic and environmental impacts of these measures using an integrated computational simulation model that combines Ocean Engineering and Economics. Our results indicate that all proposed measures support the IMO’s intermediate emission reduction targets through 2035, cutting absolute emissions by more than 50%. However, economic impacts vary significantly across regions, with most of Africa, Asia, and South America experiencing the greatest adverse effects on GDP and trade. Among the measures, the GHG levy exerts the strongest pressure on economic activity and food prices, while a revised fuel intensity mechanism imposes lower costs, particularly in the short term. Revenue redistribution mitigates GDP losses but does so unevenly across regions. By leveraging a general equilibrium model (GTAP) to capture indirect effects often overlooked in prior studies, this analysis provides a comprehensive comparison of policy impacts. The findings underscore the need for equitable and pragmatic decarbonization strategies in the maritime sector, contributing to ongoing IMO policy discussions. Full article

Global food supply chains face mounting vulnerabilities due to climate change and environmental variability, with particularly severe implications for import-dependent nations like Qatar, where over 90% of food supplies rely on international trade. This high import dependency creates unique challenges, including supply disruptions, price volatility, and food security risks, especially as climate variability increasingly affects major food-exporting regions. This study develops a multi-objective optimization framework to enhance the resilience of Qatar’s food import system by integrating economic, environmental, and crop water requirement considerations, modeled as a stochastic variable. The framework addresses both average performance and worst-case scenarios using stochastic and robust optimization approaches, evaluating trade partners for three key crops—tomatoes, onions, and cucumbers. Results identify optimal suppliers that minimize costs, environmental emissions, and water usage variability, with Turkey contributing 42.10% of total imports, Iran 13.76%, and the Netherlands 9.52%. The findings demonstrate that a diversified import strategy significantly reduces vulnerability to climate-induced disruptions and improves supply chain stability. This research provides actionable insights for policymakers, including; (1) optimal supplier diversification targets to balance risk and efficiency, (2) specific trade partner recommendations based on multiple sustainability criteria, and (3) quantitative frameworks for assessing import portfolio resilience.

This article analyses the impacts of the Russia–Ukraine conflict and the COVID-19 pandemic on the supply chain and logistics related to the management of agro-food production based on a comprehensive review of the scientific literature. The challenges and lessons posed by market dependence in a scenario of globalization through monopolies and oligopolies in the production and export of agro-food are assessed, highlighting the vulnerability and uncertainty faced when an international conflict occurs. The review examines the format of globalization versus glocalization, analyzing their respective advantages and disadvantages in supply chains and management in the context of two major crises such as the COVID-19 pandemic and the armed conflict between Ukraine and Russia. Likewise, the resilience of agro-food and agro-industrial systems that were negatively affected by food insecurity and food price inflation in parts of Europe, Africa, and other regions of the planet is analyzed. By identifying opportunities arising from these challenges, the research offers insights into fostering a more robust agro-food supply chain that is more adaptable to global crises based on the geographic location and regional development of agribusinesses capable of responding to demand in the event of a global crisis such as a pandemic or armed conflict.

Background: Determinants and motives related to food selection have evolved in a globalized and changing world. The traditional and useful Food Choice Questionnaire (FCQ), created in 1995, needs to be updated, adapted to new scenarios, and validated. Objectives: This study aimed to: (1) assess face validity (FV) of the original 36-item FCQ, (2) generate an Updated-FCQ (U-FCQ) and assess its content validity (CV) (instrument suitability), and (3) evaluate its construct validity and reliability in a Spanish-speaking population from Mexico. Methods: FV involved a panel of nutrition professionals (NPs) rating the original items’ clarity, relevance, specificity, and representativeness. A literature review process updated the FCQ by adding new items. CV with a second NP panel allowed calculating content validity ratio (CVR). Construct validation was performed via exploratory and confirmatory factor analysis (EFA-CFA). Internal consistency through Cronbach’s alpha (CA) and test–retest reliability via intra-class correlation (ICC) were assessed. Results: The FV (n = 8) resulted in the modification of 11 original items. The literature review added 36 new items (15 from previous adaptations and 21 original items). The CV (n = 13) identified nine items (non-acceptable CVR), prompting reformulation of seven and removal of two. The NPs’ feedback added six new items. The EFA-CFA (n = 788) developed a 75-item U-FCQ with eight dimensions: sensory appeal, mood, health and nutritional content, price, food identity, environmental and wildlife awareness, convenience, and image management. CA ranged from 0.74–0.97 (good–excellent) and ICC from 0.51–0.78 (moderate–good). Conclusions: This study provides a useful instrument for the assessment of food choices and lays the groundwork for future cross-cultural comparisons, expanding its applicability in wider settings.

Fraudulent and adulterated food is produced mainly to reduce prices and attract consumers’ attention whilst threatening their economic interests, health, and safety. As such, this type of activity should be eliminated. This study’s aim was to identify the most common hazards related to food fraud and adulteration, reported in the Rapid Alert System for Food and Feed (RASFF) between 2000 and 2021, taking into account the product category (including individual products), country of origin, and notification type. We used Microsoft Excel (filtering, vertical-searching, transposition, and pivot table functions) and Statistica 13.3 (two-way joining cluster analysis) to analyse similarities between the hazards identified throughout the research period. Notifications relating to food fraud and adulteration accounted for 18.7% of all RASFF notifications, fluctuating between 1000 and 1200 per year in recent years. These mainly included hazards related to composition and novel foods in dietetic foods, food supplements and fortified foods, sulphites in fruits and vegetables, colours in cereals and bakery products, or Sudan in herbs and spices. Dietetic foods, dietary supplements, and fortified foods were mainly reported as alerts and information notifications, meaning that they were already available on the common European internal market. The other products originated mainly from outside the European Union (Asia—Turkey, Uzbekistan, India and Africa—Ghana, Nigeria) and were submitted on the basis of border rejections. Therefore, it is necessary to continue closely monitoring imported products at the EU border to ensure food safety, avoiding fraud and adulteration and protecting consumers’ financial interests.

China is the largest soybean importer and consumer in the world. Soybean oil is the most-consumed vegetable oil in China, while soybean meal is the most important protein feed raw material in China, which affects the costs of animal husbandry. Volatility in the international soybean market would generate risk spillovers to China’s soybean industrial chain. This paper analyzed the channel of risk spillover from the international soybean market to China’s soybean industry chain and the asymmetry of the risk spillover. The degree of risk spillover from the international soybean market to the Chinese soybean industry chain was measured by the Copula–CoVaR model. The moderating role of inventory and demand in asymmetric risk spillovers was analyzed by quantile regression. We draw the following conclusions: First, the international soybean market impacts China’s soybean industry chain through soybeans rather than soybean meal and oil. The price fluctuation of China soybean market is obviously lower than that of the international soybean market. Second, there are apparent asymmetric risk spillovers from the international soybean market to China’s soybean industry chain, especially the soybean meal market. Third, increasing the Chinese soybean inventory and growing demand could effectively prevent the downside risk spillover from international markets to China’s soybean market. This also explains the asymmetry of risk spillovers. The research enriches the research perspective on food security, and the analysis of risk spillover mechanisms provides a scientific basis for relevant companies to develop risk-management strategies.

Agroforestry is often seen as a sustainable land-use system for agricultural production providing ecosystem services. Intercropping with food crops leads to equal or higher productivity than monoculture and results in food production for industry and subsistence. Low rubber price and low labor productivity in smallholdings have led to a dramatic conversion of rubber plantations to more profitable crops. The literature analysis performed in this paper aimed at better understanding the ins and outs that could make rubber-based agroforestry more attractive for farmers. A comprehensive search of references was conducted in March 2023 using several international databases and search engines. A Zotero library was set up consisting of 415 scientific references. Each reference was carefully read and tagged in several categories: cropping system, country, main tree species, intercrop type, intercrop product, level of product use, discipline of the study, research topic, and intercrop species. Of the 232 journal articles, 141 studies were carried out on rubber agroforestry. Since 2011, the number of studies per year has increased. Studies on rubber-based agroforestry systems are performed in most rubber-producing countries, in particular in Indonesia, Thailand, China, and Brazil. These studies focus more or less equally on perennials (forest species and fruit trees), annual intercrops, and mixed plantations. Of the 47 annual crops associated with rubber in the literature, 20 studies dealt with rice, maize, banana, and cassava. Agronomy is the main discipline in the literature followed by socio-economy and then ecology. Only four papers are devoted to plant physiology and breeding. The Discussion Section has attempted to analyze the evolution of rubber agroforestry research, progress in the selection of food crop varieties adapted to agroforestry systems, and to draw some recommendations for rubber-based agroforestry systems associated with food crops.

Conventional agriculture relies on non-renewable rock phosphate as a source of phosphorus. The demand for food has led to increased phosphorus inputs, with a negative impact on freshwater biodiversity and food security. The importation of phosphorus fertilizers makes most food systems vulnerable to phosphorus supply risks. The geopolitical instability generated by the pandemic and the current Russia–Ukraine conflict, which has led to a 400% increase in phosphorus commodity prices, offers the international community and institutions an opportunity to embrace the global phosphorus challenge and move towards a more circular system. Here, we discuss an integrated and multi-stakeholder approach to improve phosphorus management in agriculture and increase the efficiency of the whole chain, highlighting the contribution of conventional breeding and genetic engineering, with a particular focus on low-phytic-acid (lpa) crops, whose grains may help in reducing phosphorus-management-related problems. In recent decades, the choice of short-term strategies—such as the use of phytase as a feed additive—rather than lpa mutants, has been carried out without considering the long-term money saving to be derived from lpa crops. Overall, lpa crops have the potential to increase the nutritional quality of foods and feeds, but more research is needed to optimize their performance. Full article

Gastronomy represents one of the main defining national cultural elements and is essential for shaping territorial identities and for tourism development, attracting both domestic and international tourists. The landscape in the center of Bucharest has gradually changed under the influence of entrepreneurial initiatives within the hospitality industry, showing at present a rather cosmopolitan urban environment. Despite the significant number of international catering units, better adapted to global tastes, Romanian-themed restaurants represent a landmark of the capital city. In this context, our study focuses on the Romanian authentic local gastronomy offered by the themed traditional restaurants in the center of Bucharest as a stimulating factor for different types of consumers. Aiming to answer several research questions, this research has a complex multi-fold methodological approach, appealing to triangulation which gathered, as main analytic methods, mapping, semantic analyses, and text visualisation, and the interview method (originally and appropriately applied for this case study to experienced employees). The main results show a complex gastronomic landscape that gathers various types of restaurants but outlines those with a Romanian ethnic theme in the center of Bucharest. The study of Romanian restaurants’ menus reveals elements of authenticity (e.g., traditional dishes and their regional denominations, local rural ingredients, old recipes, and cuisine techniques) as factors of attractiveness for consumers and as competitive advantages in their market. Moreover, interviews with staff representatives outline restaurants’ atmosphere, originality, and price–quality ratio of their food as the main attractive elements for both autochtonous customers and tourists and which offer an advantage in the market. The present study may interest multiple stakeholders, focusing on the development and evolution of the hospitality industry in Romania. Full article

The content of this paper presents the research results of a three-year research project in which a multi-criteria evaluation model (according to the DEX methodology) was developed for the evaluation of three different food sectors (represented by a cattle breeding chain, a pig farming chain, and a milk production chain) with added value in Slovenia. Indicators for the assessment of the economically, socially, and environmentally sustainable development of food chains were taken into account. The data for the analysis, such as prices and costs of food, wage levels by sector, food miles and others, were obtained from various public services between 2020 and 2023. The final qualitative assessment of the food sectors was uniform (“average”), while the longest analysis of the results using the plus-minus-1 analysis method showed the reasons for such an assessment in individual sectors (such as the ratio between the price of agricultural products and the price of agricultural inputs is poor, the ratio between average gross salary in the individual food sector and gross salary in the agricultural sector is poor, etc.). In addition to the results already mentioned, recommendations or suggestions for building a sustainable food chain were made using the results of the modelling. The research results contributed to a better understanding of the importance of stable relationships between different groups of indicators and later showed their importance for improving the functioning of agri-food chains. The results of the research will help various stakeholders (such as the agricultural advisory service, decision-makers at the level of agricultural policy, researchers in further analyses, and especially the international professional public interested in various case studies from EU countries) to further analyse and plan for the organisation of the agricultural sector.

Non-communicable diseases are a major health burden worldwide, and they all share diet as common risk factor. In this context, understanding the complexity of eating behaviours can be useful both at the individual and population level for prevention and treatment. Foremost, there is a need for reliable and simple tools to assess eating behaviours, both for public health research and clinical practice. The aim of this study was to validate in Romanian and test by comparison two internationally popular questionnaires of eating behaviour: The Dutch Eating Behavior Questionnaire (DEBQ), which assesses emotional, external and restricted eating styles, and The Eating Motivation Survey (TEMS), short form, which investigates 15 determinants of food intake (taste, habits, need and hunger, health, convenience, pleasure, tradition, considerations related to the origin of food, social, price, appearance, weight control, social norms and social image). Methods: We tested (with the consent of the authors of the original questionnaires) the psychometric properties of the Romanian versions of DEBQ and TEMS on an adult general population and explored associations of eating behaviour with weight status with both questionnaires. Our study showed factor loads similar to the original version of the questionnaire for DEBQ and a very good internal validity (Cronbach's alpha fidelity coefficient greater than 0.8) for both DEBQ and TEMS. Emotional eating in DEBQ and items related to emotional eating in TEMS showed the strongest correlation with weight, but for all scales of DEBQ, there were further information given by TEMS. This study enables the use of the DEBQ and TEMS in Romania for the adult population. We also consider that the two questionnaires could be used together for developing more adequate strategies to reduce the burden of nutrition-related diseases. Full article

In China, milk is promoted both as an optimal food and gift for older adults. To understand the product factors affecting older Chinese adult milk choices, choice simulations and surveys were conducted in Beijing, Shanghai, Guangzhou, Chengdu, and Shenyang, China. Participants (n = 1000, aged 45–55 years old and 65–75 years old) were asked to choose one milk product out of eight alternatives for self-consumption and gifting, respectively, and to indicate product factors under their considerations. Results showed that, for self-consumption, the top four most popular milk products (two with domestic brands and two with international brands) were chosen by 84.9% of the participants. Females and younger participants were more open to international brands than their counterparts. Popular milk products differed across cities, potentially due to brand familiarity. Brand (85.9%), on-the-pack, nutrition-related well-being messaging (72.9%), price (63.1%), shelf-life (63.0%), and production date (57.6%) were the most frequently reported product factors considered when choosing milk. More males considered price than females (66.9% vs. 60.0%, p = 0.02). Female and older participants showed greater concern for certain detailed product factors, such as production date and shelf-life, than their counterparts. Variation across cities was limited, with participants in Chengdu and Shenyang showing less concern for certain product factors such as on-the-pack, certificate-related well-being messaging. When milk products were chosen as a gift, although overall milk choice ranking remained similar, package style received increased attention (32.0% vs. 40.8%, p < 0.01), whilst all other product factors, especially price (63.1% vs. 49.5%, p < 0.01), were considered by significantly fewer participants. These findings provide valuable marketing insights, helping to understand consumer preferences and considerations in the process of milk purchase decision-making. Full article
