This study employs complex network analysis and ecological network resilience to investigate the historical dynamics of global staple food trade network resilience from 1986 to 2020. Additionally, structural decomposition and econometric analysis are used to explore the drivers of resilience from both internal and external perspectives. The findings reveal significant heterogeneity in the resilience dynamics of global staple food trade when faced with external shocks such as COVID-19 and geopolitical tensions. Staple foods, i.e., wheat, rice, and potatoes have demonstrated increased resilience in response to pandemic-related disruptions. However, the aggregated staple food network is more adversely affected by geopolitical tensions compared to the five individual staple food networks, with a more pronounced inhibitory effect on its resilience. Potatoes emerge as the most resilient staple, while soybeans exhibit the lowest resilience. Interestingly, the inclusion of a greater variety of staple foods in the aggregated basket does not necessarily enhance resilience. For instance, integrating potatoes, characterized by high network efficiency, increases resilience, whereas integrating soybeans, with low network efficiency, reduces resilience. Furthermore, the diversity of trade flows and trade partners plays a crucial role in enhancing resilience. This comprehensive analysis provides valuable insights for policymakers and stakeholders aiming to bolster the resilience of the global food trade network.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 4","pages":"845 - 865"},"PeriodicalIF":5.6,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500645","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}

A comparative approach to the institutional settings designed to secure the safety of raw cow milk in Brazil, Canada and Italy substantiates the analysis. Beyond the variety of institutional “configurations” characterizing these cases, the investigation shows how crucial the implementation by meso-institutions is of otherwise similar norms and rules in determining their effectiveness. Meeting food safety regulations depends on the capacity of meso-institutions to fulfil specific functions, the accomplishment of which can be assessed only through related tasks. Lessons are drawn with respect to efficiency, the trade-off between centralized and decentralized solutions, the impact on the organization of supply chains, and the necessity for public policies to pay special attention to meso-institutions in the design and implementation of food safety regulation.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 4","pages":"1045 - 1058"},"PeriodicalIF":5.6,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500644","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 use longitudinal panel household survey data from a quasi-experimental study collected at three rounds: before, one year, and two years after the horticultural intervention ended. We use propensity score matching and fixed-effect regression models to estimate the average treatment effects on the treated. We find that the vegetable support significantly improves food security by 21% and 19% in the short- and medium-term, respectively. More specifically, we find that the intervention significantly increased the consumption of nutrient-rich food groups such as vegetables, root tubers, fruits, eggs, pulses and nuts, milk, and oil and fats. Moreover, we find that the intervention reduces in the short-term the use of harmful coping strategies by 17%. However, this effect dissipates two years after the end of the intervention.

Fish holds potential to help address these deficiencies but remains barely incorporated in nutrition policies and strategies, partly due to a lack of supporting evidence. We address this gap by analyzing sixteen years of fisheries production and trade data from marine, freshwater, and aquaculture systems to evaluate fish nutrient supply, assess changes in supply, and determine the contributions the current supply could make to meet the nutritional needs of children under five years in Kenya. Despite an 11% increase, through time, in the total supply of fish, there was a 24% decline in per capita fish consumption due to fishery changes and increased fish demand. Furthermore, a 21% decline in supply of fish from inland freshwater systems resulted in a 25–40% decline in nutrient supply. Based on the current supply of fish, Kenya’s per capita consumption of 2.5 kg/yr is below WHO recommendations of 10.4 kg/yr. However, this supply has the potential to support nearly 13 million Kenyans at this WHO recommendation. If supply was targeted towards vulnerable groups, such as children under five years, it could supply all children in Kenya with one-third of their calcium, selenium, and protein and over 70% of children in Kenya with one-third of their iron, zinc, and omega-3 polyunsaturated fatty acids requirements. Therefore, fish can play an important role in supporting nutritional security in Kenya if strategic interventions involving all relevant sectors are considered, to reduce identified nutrient deficiencies.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 4","pages":"951 - 971"},"PeriodicalIF":5.6,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01459-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141356342","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}

It identifies out-shopping as a factor explaining why existing studies observing food prices at local stores in remote areas find much higher prices than at urban stores, while studies observing actual purchases of household in remote areas find small differences in food expensiveness with urban households. To investigate this difference, a food expensiveness index was constructed using home scanner data measuring households’ actual purchases. Data from the 2020 COVID-19 lockdown, when travel restriction limited out-shopping, were compared with the same period in 2019 when such restrictions were not in place. The results find that the premium paid in remote rural areas was small overall, but a statistically significant increase during lockdown was found for those households that lost access to discount stores because of movement restrictions. This result indicates that out-shopping is an important factor limiting food expensiveness in remote areas of Scotland and thus ensuring food affordability. Data suggest that approximately 42 percent of households in Scotland remote areas rely on out-shopping for obtaining affordable food.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 4","pages":"1019 - 1029"},"PeriodicalIF":5.6,"publicationDate":"2024-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01456-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141369612","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}

Our results show that per capita meat consumption is mainly driven by socioeconomic factors, such as national GDP and urbanization. However, the strength of these drivers declined between 1990 and 2018. Pork, beef, and poultry consumption are mainly driven by socioeconomic factors, whereas mutton consumption appears driven by other factors such as the per capita agricultural land.
