摘要

珍珠小米在边缘地区具有抵御气候相关风险的巨大潜力。然而,它如何为小农户一级的收入和粮食安全做出贡献,还有很多未知之处。因此,本研究评估了珍珠小米对阿姆哈拉东北部边缘干旱热带地区农民收入和粮食安全的贡献、其生产限制以及利益相关者之间的联系。该技术已推广了五年(2015-2019),并对223个样本的数据进行了分析。即使在恶劣的气候条件下,珍珠小米新技术也能提供比高粱更好的产量(1420 kg·ha-1)和净收益(42328 ETB ha-1)。尽管生产成本较高,但多年来其额外回报(31638)和有效收益(28838)都较高。感官评价结果表明,“Enjera”、“Tella”、面包和粥分别是农民对珍珠小米的第一、第二、第三和第四食物类型选择。接受这项技术的趋势在农民中占了很大一部分,79.5%的参与者应用了完整的技术包。由于劳动力短缺、技术复杂性和实践培训不足,那些没有申请完整方案的人这样做了。因此,建议采用气候智能珍珠小米作物技术,以便在边缘干旱热带地区实现更好、一致的生产。

PEARL MILLET, THE HOPE OF FOOD SECURITY IN MARGINAL ARID TROPICS: IMPLICATIONS FOR DIVERSIFYING LIMITED CROPPING SYSTEMS
Pearl millet has great potential to withstand climate-related risks in marginal areas. However, much remains unknown as to how it contributes to income and food security at the smallholder level. As a result, this study assessed the contributions of pearl millet to the farmers’ income and food security, its production constraints, and connections between stakeholders in the marginal arid tropics of Northeast Amhara. The technology was promoted for five (2015–2019) production years, and data from 223 samples were analyzed. The new pearl millet technology provided better yield (1420 kg·ha-1) and net return (42328 ETB ha-1) than sorghum, even in difficult climatic conditions. Despite the higher cost of production, its additional returns (31638) and effective gains (28838) were higher across the years. The results of the sensory evaluation revealed that “Enjera”, “Tella”, Bread, and Porridge were the farmers’ 1st, 2nd, 3rd, and 4th food type choices of pearl millet, respectively. The trend towards acceptance of the technology made up a large number of the farmers, as 79.5% of those who participated applied the full technology package. Those who did not apply the full package did so due to labor shortages, technological complexity, and insufficient practical training. Therefore, climate-smart pearl millet crop technology is recommended for better and consistent production in marginal arid-tropical areas.
