Abstract

Small-scale farmers make up the majority of farmers worldwide yet experience particularly high rates of food insecurity. A growing body of literature explores pathways to food and nutrition security among small-scale farmers but has yet to reach consensus on the most effective pathways (e.g., crop specialization for market sale versus on-farm crop diversification for home consumption) to improve livelihoods. Using structural equation modelling (SEM) based on data drawn from the 2015/16 Uganda National Panel Survey, this study considers how farm and household characteristics including gender, age, education, farm size, region, and off-farm income relate to market engagement (farm sales, market purchases) and on-farm crop diversity (Simpson’s diversity). We then further examine how market engagement and on-farm crop diversity relate to household livelihood outcomes including dietary diversity and food security (number of food secure months). Findings suggest that both higher levels of market engagement and on-farm crop diversity are associated with increased dietary diversity. Higher levels of crop diversity—whether for market sale or for self-consumption—are strongly associated with improved food security. Market engagement is positively associated with increased dietary diversity, and this association is particularly strong for market purchases. Together, these findings highlight the potential for both market-based strategies and on-farm crop diversity to contribute to food security goals in Uganda, providing further evidence that these strategies can be complementary.

市场参与、作物多样性、饮食多样性和粮食安全：乌干达小规模农户的证据

小规模农户占全世界农民的大多数，但他们的粮食不安全率却特别高。越来越多的文献探讨了小规模农户获得粮食和营养安全的途径，但尚未就改善生计的最有效途径（如面向市场销售的作物专业化与面向家庭消费的农场作物多样化）达成共识。本研究以 2015/16 年乌干达全国面板调查的数据为基础，采用结构方程模型（SEM），研究了农场和家庭特征（包括性别、年龄、教育程度、农场规模、地区和农场外收入）与市场参与（农场销售、市场采购）和农场作物多样性（辛普森多样性）之间的关系。然后，我们进一步研究了市场参与度和农场作物多样性与家庭生计结果的关系，包括饮食多样性和粮食安全（粮食安全月数）。研究结果表明，较高的市场参与度和农场作物多样性都与饮食多样性的增加有关。更高水平的作物多样性--无论是用于市场销售还是自给自足--都与粮食安全的改善密切相关。市场参与与膳食多样性的增加呈正相关，这种关联在市场购买方面尤为明显。总之，这些发现凸显了基于市场的战略和农田作物多样性在促进乌干达粮食安全目标方面的潜力，进一步证明了这些战略可以相辅相成。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
