However, some studies show that increased meat consumption poses a health burden while others show dietary diversity promoted by away from home enhances health. As a result, the effects of away from home on dietary nutritional quality remain inconclusive. Moreover, estimates of total food consumption are underestimated without considering away from home. Herein, we constructed away from home models (<i>R</i>^<i>2</i> = 0.59) to assess its impacts on the quantity and quality of food consumption. By 2020, away from home accounted for 18% (233.37 g) of total consumption in urban areas and 8% (81.80 g) in rural areas. Although, at the national scale, away from home consumption of meat, poultry, and aquatic products led to decreased dietary nutritional quality in urban areas from 2000 to 2020 and in rural areas since 2015, by 2020, three urban provinces and 12 rural provinces still showed improvements in dietary nutritional quality from such consumption. Additionally, overall dietary nutritional quality of away from home impact in urban areas improved from 2000 to 2015 but decreased in 2020, whereas rural areas saw consistent improvement across all years, suggesting the divergent impacts on diet nutrition quality across urban and rural China. Our findings underscore the urgency and necessity of extensively strengthening national nutritional education and developing specific nutrition-health policies tailored to economic conditions. This study also provides critical data for accurate food consumption and life cycle evaluations, promoting sustainability in the food system.</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 1","pages":"41 - 56"},"PeriodicalIF":5.6,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388699","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}

Redirecting resources edible by humans to direct consumption as food can increase resource use efficiency and food supply, however, what can be considered as edible by humans is context dependent. The objective of the present study is to assess the net contribution of ten contrasting tilapia production systems from eight different countries to the supply of nutrients of importance for human health. To do so we calculated the human-edible nutrient conversion ratio (HeNCR), which is the human-edible nutrients in the inputs (feed) divided by the human-edible nutrients in the outputs (animal products) of the systems. We showed that tilapia systems can be net producers of proteins, but that in general, much more human edible micronutrients (5 to 175 times) and EPA + DHA (about 7 times) were in the feed used than in the fish produced. Four scenarios combining different definitions for feed and fish edibility were tested to explore the effect of different dietary changes on the performances of the tilapia systems. Scenario analysis revealed that the direct use of edible ingredients as food generates more nutrients than the consumption of fish. Consumers’ preferences, and therefore our definition of what is edible, may have to evolve in order to maximize food resource use.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"57 - 72"},"PeriodicalIF":5.6,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388705","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}

Despite progress in livestock science research in recent years, the seasonal availability and quality of feed remains one of the key challenges to livestock productivity in Southern Africa. In particular, dry weather conditions, the lack of rain and lower temperatures in the dry season cause herbaceous plants to die back and browse species to defoliate, limiting the abundance, quality, and variety of feed available. This creates a ‘Nutritional Feed Gap’, defined here as the combined effect of the sharp reduction in both forage quantity and quality from the wet to the dry season and the risk that it poses to ruminant production systems and the food security of the people and communities reliant on them. Understanding the nature and extent of how seasonality impacts ruminant production potential can thus contribute towards mitigating negative impacts of extreme weather and climate change on food systems. In this review, we characterise this nutritional feed gap in terms of forage abundance and nutrition as well as discussing how climate change may shape the future nutritional landscape. Whilst some forage nutrient concentrations varied little by season, crude protein and phosphorus were consistently found to decrease from the wet season to the dry season. We also identify a shortfall in primary research that assess both forage quality and quantity simultaneously, which forms part of a broader knowledge gap of our limited understanding of the impact of limiting factors to ruminant production on short and long-term food security across Southern Africa.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"73 - 100"},"PeriodicalIF":5.6,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01509-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388862","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}

This research leverages primary data from 1,099 farm households to explore the nexus between on-farm demonstrations (OFDs), aspiration formation, and food security. Utilizing instrumental variable (IV) estimates, our analysis highlights a positive association between OFDs and income aspiration formation, as well as food and nutrition security.

Farm households with higher income aspirations and those experiencing greater food insecurity derive more significant benefits from OFDs.

The results show that households with diverse income sources, including multiple farm products, non-farm businesses, and remittances from absent members, are less likely to reduce food consumption quality and quantity, and be in the lower tail of food expenditure distribution. -However, households in the upper tail of the food expenditure distribution aggressively stock up on food in the second quarter of the year, fearing that lockdown measures would interrupt the food supply. These households tend to have an urban way of living characterized by salaried jobs, small family size, high educational attainment, and proximity to the capital city. The levels of food expenditure remain high even after the lifting of lockdown and movement restrictions, and the reason might be possible uncertainty about crop harvests, despite the eventual good harvests in the year. Overall, these findings suggest that diversification of income sources for rural households in developing countries can help households cope with disruptions to food production and supply chains. The findings also suggest that policies to ensure food access during the pandemic should target households with limited income sources and those in the lower tail of the food expenditure distribution.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"101 - 125"},"PeriodicalIF":5.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01515-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388933","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}

The results indicate a dietary transition is occurring in Indonesia, characterized by increased consumption of wheat, chicken, fish, sugar-sweetened beverages, processed, ultra-processed, and ready-to-eat foods, and a decline in the consumption of green leafy vegetables and fresh legumes across all area categories. Diet quality is declining in all area categories, however, urban areas showed the most accelerated decline, with declining dietary diversity, decreasing consumption of healthy foods, while increasing consumption of less healthy foods and the highest consumption of ultra-processed foods. Furthermore, foods consumed more in urban (vs. rural) and high-TCL (vs. low-TCL) areas, such as wheat, broiler chicken, dairy, and packaged foods, are associated with modern diets and sourced from farther away, indicating accelerated modernization and delocalization of diets. Conversely, foods consumed more in rural and low-TCL areas, such as traditional staple foods, free-range eggs, and dark green leafy vegetables, are considered more locally sourced and traditional. We conclude that dietary transitions occur across all regions, but the modernization of diets is more accelerated in urban and high-TCL areas. Given the mixed health consequences of modern diets, policies should anticipate negative impacts while preserving positive aspects.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1313 - 1331"},"PeriodicalIF":5.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01488-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821476","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}

However, the extent to which agroecological practices will generate the yields required to ensure sufficient food globally remains unclear. This notion is particularly true in the context of Africa, where agricultural productivity is low but levels of hunger and malnutrition are high. To address this knowledge gap, this article undertakes a systematic review of empirical studies to assess the overall status of agroecology-related research in Africa. Using descriptive and meta-analytical methods, we evaluate empirical evidence on the effect of agroecological practices on land and labour productivity. Our analysis of 501 peer-reviewed articles reveals that the body of agroecology-related literature in Africa has been growing in the past 10 years from approximately 10 to more than 70 studies per annum before and after 2014, respectively, with a strong focus on East Africa, particularly Kenya. The majority of the reviewed studies relate to but do not mention agroecology in the title or abstract. Thus, solely relying on studies that use the term may introduce bias and overlook valuable research contributions to the field. The meta-analysis could identify 39 agronomic studies with 392 observations in which agroecological practices were compared to monocrop systems (defined as plots where similar plants grow alongside each other simultaneously and sequentially from one season to the next) with or without inputs as the control groups. The meta-analysis indicates that agroecological practices are associated with a positive and significant difference in land productivity, compared to that for monocrop systems especially so when monocrops are grown without inputs. However, the size and direction of yield differs by practice, crop, climatic factor, soil property and type of control.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"207 - 229"},"PeriodicalIF":5.6,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01504-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388826","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}

The present study examines the essential elements of an urban food system by employing a Bayesian network as a causal framework. By integrating survey data from households and food outlets with spatial information, a food systems model was created to test policy interventions. The study demonstrates the challenges of intervening in complex urban food systems, where dietary choices are shaped by various factors, often in a spatially heterogeneous manner. Interventions do not always benefit the targeted groups and are sometimes ineffective as result of system interactions. Our study shows that Bayesian network models provide a powerful tool to effectively analyse the complex interactions within such systems, thereby enabling the identification of optimal combinations of multifactor interventions.

In a country such as India, where consuming leftovers and reducing food wastage is an ingrained moral and religious belief as opposed to other cultures, especially in some highly industrialised ones, this article explores the possibility that providing citizens with solutions that are mindful of their cultural acceptability will lead to the effective implementation of policies at micro levels. One of the facets of food security, food utilization, is an aspect which can be improved at the individual and household levels. It constitutes one such opportunity in India because of the inherent belief system of the country. My investigation is based upon the theory of Johan Pottier (1999) who stated that while food security is a global issue and much policies is directed at that scale, policies are not well-grounded in a bottom-up understanding of foodscapes of those at whom it was aimed. The paper uncovers unanimity regarding the notions of consuming leftovers and curbing food waste as religious beliefs among various religions across India. It also compares the cultural acceptability of reusing leftovers and reducing wastage in India with developed nations such as the USA and the UK.
