摘要

尽管联合国可持续发展目标强调通过促进可持续农业在全球范围内改善膳食多样性和整体营养状况,但在包括撒哈拉以南非洲地区在内的许多低收入国家,膳食摄入不够多样化仍是一个公共卫生问题。本研究的主要目的是收集相关信息,以便更好地了解家庭膳食多样性,并探讨生产多样化在家庭膳食和营养中可能发挥的作用,从而实施适当的干预措施,以加强对营养敏感的农业,同时考虑到农业生态系统的不同特征。采用了基于农业生态系统的横断面研究设计。数据主要通过半结构式问卷收集,并通过描述性和推论性统计以及多层次混合效应模型进行分析。结果显示,家庭通常的膳食摄入模式单一,以淀粉类主食为主,水果、蔬菜和动物源性食物的摄入量非常有限。每五个家庭中就有一个家庭的膳食多样性不足,但在不同的农业生态系统中差异显著。约 26% 的膳食多样性异质性归因于农业生态系统层面的因素。在模型的固定效应部分,生产多样化、财富状况、每日进餐次数、市场准入和年平均降雨量与家庭膳食多样性状况显著相关。我们的研究结果有助于深入了解不同农业生态系统区域自给农户膳食多样性与生产多样化之间的联系。因此,在设计营养敏感型农业时,了解农业生态系统的差异和农村自给农作的当地背景是一个关键点。

Agroecosystem-based analysis of household dietary diversity and its linkage with agricultural production diversification in the Upper Blue Nile Basin, Ethiopia: Multilevel analysis approach

Even though the UN's Sustainable Development Goals emphasize improving dietary diversity and overall nutritional status globally by promoting sustainable agriculture, inadequately diversified dietary intake remains a public health problem in many low-income countries, including in Sub-Saharan Africa. The main objective of this study was to gather relevant information to gain an improved understanding of household dietary diversity and explore the role that production diversification could play within household diets and nutrition so that appropriate interventions could be implemented with the goal of enhancing nutrition-sensitive agriculture while also considering the varied features across the agroecosystems. Agroecosystem-based cross-sectional study design was employed. Data were collected predominantly through semi-structured questionnaires and analyzed by descriptive and inferential statistics, and a multilevel mixed-effect model. Results showed that the usual dietary intake of households has a monotonous pattern dominated by starchy staple foods, and consumption of fruits, vegetables, and animal-sourced foods was very limited. One out of five households had inadequate dietary diversity but varied significantly across agroecosystems. About 26% of the heterogeneity in dietary diversity was attributed due to agroecosystem level factors. In the fixed-effect part of the model, production diversification, wealth status, number of meals per day, market access, and annual mean rainfall were significantly associated with household dietary diversity status. The findings of our research contribute to give insights on the linkage between dietary diversity and production diversification among subsistence rural farmers across contrasting agroecosystem zones. Therefore, understanding agroecosystem variations and local context in the rural subsistence farming setup is a key point in designing nutrition-sensitive agriculture.

期刊介绍: Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action. Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers. All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
