As a result, there has been a corresponding increase in the demand for animal source foods. In order to meet this demand, most countries have resorted to intensifying the production of conventional livestock. However, this increase in production comes with several environmental, nutritional, gender-related and economic challenges that are a rising concern. It is therefore imperative to explore the comparative advantages and disadvantages of other livestock species, which are currently consumed in SSA but are not recognised in widely adopted policies. Herein, using a novel conceptual framework, we present a systematic review of four selected neglected species, namely, grasscutter, guinea fowl, guinea pig, and rabbit. The review was conducted following the checklist for Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA), and 89 sources of literature were included. The results highlight that embracing these neglected livestock species could confer several benefits, including an enriched nutritional profile (high-quality protein, low fat, high dressing percentage), increased gross economic returns, environmental sustainability, and sustained empowerment of minority groups, especially women. Overall, this review shows the untapped nutritional and socio-economic potential of neglected livestock species, which, if incorporated into mainstream production, could improve food security and reduce unemployment in SSA.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"161 - 183"},"PeriodicalIF":5.6,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01503-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388936","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}

Using household survey data from 945 smallholders in Xishuangbanna Dai Autonomous Prefecture, the study employs a two-stage Tobit model to estimate the impact of agricultural transformation on the household food self-sufficiency of smallholders. The results, which are based on 2018 data, reveal that the average self-sufficiency rate for all foods was 40.7%, and that of grain was even lower at 33.4%. Changes in land use, specifically the substitution of food crops with cash crops, and labor allocation, namely, engagement in off-farm labor markets, are the main drivers of the reduction in household food self-sufficiency. A 10% increase in the share of cash crops results in a 4.2% decrease in the rate of household food self-sufficiency, whereas adding one additional crop to the portfolio leads to a 6.4% increase. Moreover, households with at least one family member engaging in off-farm labor have a 13.1% lower self-sufficiency rate than those without. This study contributes to a better understanding of the household food self-sufficiency of smallholders in the context of land use change and rising off-farm employment, while the findings provide a reference for policy design to ensure household food security for smallholders in the upper Mekong region.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"231 - 255"},"PeriodicalIF":5.6,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388827","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}

And yet, scholars tell us that the concept of food security has historically been muddy, and difficult to pin down, resulting in a plethora of assessments, tools and indicators, with significant variability. There is growing scholarly agreement that moving beyond “food security” is essential and that scholars, practitioners, and policymakers would do well to conceptualize agri-food systems as complex, and pay more attention to socio-ecological dynamics, political systems, culture, and health and well-being. Food Sovereignty offers a conceptual framework to bring together these dynamics and in the past decade, there has been an emerging body of Food Sovereignty metrics, assessments and indicators that highlight the complexities of the relationships between food, health, environments, culture, gender relations, and economies through a food sovereignty lens. At the local level, food-sovereignty assessments have gained traction in the past decade, but we know very little about these tools, where they align and diverge, and whether they engage with multi-scalar analysis of food systems. In this paper, I examine these community-based food sovereignty assessments, paying attention to how they align and diverge and illustrating what researchers, communities and policymakers can learn from community-based FSAs to date.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"17 1","pages":"257 - 273"},"PeriodicalIF":5.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388892","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}

Wheat grain samples were collected from China's major production areas during both the harvest and storage stages to investigate the temporal and spatial trends in fungal distribution. The results revealed significant differences in the fungal diversity and communities during different stages of wheat processing, with a more complex fungal co-occurrence network in stored wheat than in harvested wheat. <i>Aspergillus</i> was the keystone taxon in the network of the stored wheat mycobiome. It was assigned to the “Unspecified_saprotroph” group and was found to contribute significantly to the differences in fungal community structure between harvested and stored wheat. We also constructed a Random Forest (RF) model to predict the freshness of the wheat grains. The RF model exhibited a strong ability to correctly determine the wheat grain stage based on the mycobiome present on the surface of the wheat grains, achieving a 98.28% accuracy rate, which confirmed the potential of mycobiome analysis for assessing wheat grain quality.

This article constructs a novel measure of food insecurity using an alternative approach based on financial needs of households, known as the household living budget (HLB). The HLB is defined as the income required to satisfy a household's essential needs, enabling it to maintain a modest yet sufficient standard of living while covering federal and state income taxes. The HLB is constructed at the census tract level and incorporates three key determinants of food insecurity: household size and composition, household income, and food costs. We demonstrate how the HLB along with publicly available data can be used to construct a food insecurity measure using a residual income approach to assess if households are able to afford paying for food expenditures and assess the qualification thresholds of the Supplemental Nutrition Assistance Program (SNAP). Food insecurity estimates are obtained for households in Washington, D.C. and benchmarked to regional results provided by a survey sponsored by the Capital Area Foodbank.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1569 - 1586"},"PeriodicalIF":5.6,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01494-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821405","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}

Final objective of this work is to guide interventions aimed at increasing effectiveness and sustainability of such mechanism in the light of the rising refugee population in the country. Taking advantage of a unique panel dataset representative of around 80% of Ugandan refugees (as of 2018), this study specifically investigates the impact of cash and food transfers on a range of outcomes related to food security and self-reliance. Results show that both transfers reduce the likelihood of implementing negative coping strategies. However, transfers’ relative effectiveness depends on beneficiaries’ characteristics, context specificity, and outcome assessed. In particular, food transfers improve households’ diet, while cash transfers are more suitable to support self-reliance, but only for refugees that cultivate a sufficient extent of land.
