Tackling nutrition insecurity remains a critical challenge in developing countries. In the predominantly rain-fed and smallholder-based farming systems of Ethiopia, production diversity and livelihood strategies of the farm households vary across geographic areas. However, the effects of household socioeconomic characteristics, production diversity, and household incomes on nutrition profiles in distinct settings have been inadequately understood. Therefore, this study was undertaken to examine the association of farming system type, sources of income, and household wealth status with household nutrition profiles in three remote locations such as Mennisa, Welmel Tiqa, and Agam Wuha that represent root crops-based farming, maize-based semi-pastoral farming, and teff-based cereal farming systems, respectively. A combination of qualitative and quantitative data collection techniques was employed. A multistage sampling procedure was used to select a total of 265 smallholder households for the structured survey interviews. Standard statistical tests and Tobit regression analyses were performed after determining the wealth category of each household. Results revealed a diversity of income sources used by each of the farm households with average values of 9 in Mennisa, 10 in Agam Wuha, and 11 in Welmel Tiqa, with the contributions of each income source varying by household wealth category and location. As expected, expenditures on food significantly exceeded those on non-food categories for poor households and vice versa for rich wealth households. The average total food variety score (FVS) for Welmel Tiqa was twice that for Agam Wuha, confirming the need for site-specific nutrition profile assessments. Despite the observed differences in household nutrition profiles among wealth categories and locations, the apparent intakes of vitamin A, vitamin B, vitamin D, and calcium were consistently below the population-level estimated average requirements across all locations. The number of adequately consumed nutrients by farm households was negatively associated with family size, age of household heads, livestock holdings, wealth categories, and irrigation use, and positively associated with crop production diversity, income diversity, and FVS. The negative association between irrigation use and nutrition security was likely due to the focus on producing crops with a high market value on land under irrigation, coupled with ineffective allocation of generated income for enhancing household nutritional outcomes. Therefore, programs that include irrigated agriculture investments should consider adopting a more integrated nutrition-sensitive interventions, including consideration of locally adapted nutritious crops, such as orange-flesh sweet potato, to address critical deficiency of Vitamin A, nutrition training coupled with development of recipes and cooking demonstrations, and marketing and promotion for nutritious crops.
应对营养不安全问题仍是发展中国家面临的一项严峻挑战。在埃塞俄比亚以雨养农业为主且以小农户为基础的农业系统中,农户的生产多样性和生计策略因地理区域而异。然而,家庭社会经济特征、生产多样性和家庭收入对不同环境下营养状况的影响尚未得到充分了解。因此,本研究旨在考察农业系统类型、收入来源和家庭财富状况与门尼萨、韦尔梅尔·提卡和阿加姆·乌哈这三个偏远地区农户营养状况之间的关联,这三个地区分别代表以块根作物为主的农业、以玉米为主的半游牧农业和以画眉草为主的谷物农业系统。本研究采用了定性和定量数据收集技术相结合的方法。采用多阶段抽样程序,共选取265户小农户进行结构化调查访谈。在确定每户的财富类别后,进行了标准统计检验和托宾回归分析。结果显示,每户使用的收入来源多种多样,门尼萨平均为9种,阿加姆·乌哈为10种,韦尔梅尔·提卡为11种,每种收入来源的贡献因家庭财富类别和地点而异。正如预期的那样,贫困家庭的食品支出显著超过非食品支出,而富裕家庭则相反。韦尔梅尔·提卡的平均食物种类总分(FVS)是阿加姆·乌哈的两倍,这证实了进行因地制宜的营养状况评估的必要性。尽管在不同财富类别和地点的家庭营养状况存在差异,但所有地点维生素A、维生素B、维生素D和钙的明显摄入量始终低于人群水平的估计平均需求量。农户充分摄入的营养素数量与家庭规模、户主年龄、牲畜存栏量、财富类别和灌溉使用呈负相关,与作物生产多样性、收入多样性和食物种类总分呈正相关。灌溉使用与营养安全之间的负相关可能是由于专注于在灌溉土地上种植高市场价值的作物,以及用于改善家庭营养状况的创收分配效率低下。因此,包括灌溉农业投资在内的项目应考虑采用更综合的营养敏感型干预措施,包括考虑种植当地适应的营养作物,如橙色果肉红薯,以解决维生素A的严重缺乏问题,开展营养培训并开发食谱和烹饪示范,以及对营养作物进行营销和推广。
