The analysis reveals significant growth in global maize trade, with the network becoming increasingly complex and dense, leading to improved efficiency. However, overall network connectivity remains uncertain, exposing vulnerabilities within the system. The trade network has developed a hierarchical structure, with four major clusters—North America-Caribbean, South America, Europe, and East Asia—dominating global trade, signaling the emergence of a multipolar trade pattern. Over time, the network has expanded eastward, with trade flows becoming more geographically diversified. Key exporters such as the United States, Argentina, and Brazil form the network’s backbone, serving as critical hubs that facilitate the flow of maize across global markets. Additionally, gateway countries like Spain play a vital role in connecting regional clusters, enhancing the overall network’s connectivity. While the resilience of the maize trade network has improved, significant node polarization remains. Central exporters remain indispensable for the network’s stability, while peripheral regions remain more vulnerable. The study underscores the importance of strengthening connectivity between key players and regions to reduce vulnerabilities and enhance the resilience of the global maize trade network. Policy recommendations are provided to ensure the sustainability and stability of the global maize supply chain, ultimately supporting global food security in the face of growing demand and potential disruptions.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 4","pages":"811 - 827"},"PeriodicalIF":6.2,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145164636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a novel socio-metabolic analytical framework and applies it to investigate how external shocks propagate within the animal product supply systems (APSS) of La Reunion Island, a French overseas department. By conceptualizing APSS as a metabolic network, we analyze characteristics that influence three vulnerability factors: exposure, sensitivity, and incapacity to cope. To analyze shock propagation dynamics, this paper introduces the distinction between cascading and domino effects: cascading effects trace the sectors and stages impacted, while domino effects highlight how the nature of disruptions evolves as they spread. Using a mixed-methods approach, we map flow dynamics and identify critical interaction nodes susceptible to convey shock propagation clusters. Drawing on stakeholder insights, our empirical findings from disruptions during the COVID-19 pandemic, the Russo-Ukrainian war, and other events reveal the interplay of different cascading and domino effects influencing the availability, accessibility and stability of animal-based products. Our findings underscore a paradox: while import-dependent local APSS are highly exposed and present vulnerabilities to external shocks, they also buffer impacts on the food supply by ensuring some degree of autonomy. The results offer insights into the systemic vulnerabilities of insular agri-food systems and provide a framework for analyzing shock propagation in complex food supply networks.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 4","pages":"829 - 844"},"PeriodicalIF":6.2,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conduct a hierarchical assessment of the embodied environmental impacts (EEIs) in agricultural trade by first mapping four specific EEIs: greenhouse gas emissions (GHG), nutrient pollution (NP), habitat disturbance (HD), and freshwater consumption (WC), and subsequently developing two composite indices, namely cumulative EEI (CEEI) and CEEI efficiency (CEEIE), to evaluate environmental trade-offs. It was found that global agricultural trade in 2017 embodied flows of 1431.9 Mt CO<sub>2eq</sub> of GHG, 17.6 Mt of NP, 276.5 Mha<sub>eq</sub> of HD, and 129.7 km<sup>3</sup> of WC. Although a handful of exporters dominated across various EEI categories, the specific countries leading in each category varied, and they did not necessarily shoulder a significant CEEI burden. The composite indices identified India as the top CEEI exporter, primarily attributable to its unsustainable trade practices. However, five major exporters, namely the USA, Canada, Russia, Brazil, and Australia, contributed to global food security and hunger reduction at relatively higher CEEIE levels. Global agricultural trade mitigates local impacts of NP by 168.5%, HD by 49.6%, and WC by 83.4%, but introduces a 32.7% increase in GHG compared to the no-trade scenario. Further trade concentration risks increasing vulnerability in the global food market and may exacerbate environmental impacts. However, a 34.3% reduction in global CEEI can be achieved when the environmental intensities of agricultural production at the country level align with the global median. These findings facilitate the shaping of sustainable agriculture and trade practices.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 4","pages":"845 - 862"},"PeriodicalIF":6.2,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we analysed the influence of these constraints and conditions between locations and ethnic communities in Marsabit County, northern Kenya. We used a participatory approach for qualitative data collection to compare the extent to which women’s personal food environments influence child-food provision among Rendille (pastoral), Borana (agro-pastoral), and Burji (crop-farming) communities. In 18 focus group discussions conducted in 2021–2022, women caregivers in six groups in these three communities rated and discussed up to 35 foods according to accessibility, affordability, convenience, healthiness, and acceptance by children. Mothers' perspectives on food characteristics associated with personal food environment factors vary depending on their contextual conditions. The ratings of food items according to these factors differed between the pastoral and agro-pastoral communities. The concepts of the food environment show how various factors affect mothers' food choices and child nutrition. These factors include location, livelihood systems, seasonality, infrastructure, household conditions, and food cultures. Therefore, food environment framing provides better strategies to inform interventions that aim to promote healthy and sustainable diets to improve children’s nutrition and well-being.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 4","pages":"883 - 904"},"PeriodicalIF":6.2,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01552-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
