以昆虫为基础的食物系统是埃塞俄比亚南部独有的，它们是数百万家庭的主食。Enset是香蕉的近亲，其整个假茎和球茎均可食用，具有极不寻常的作物性状组合，包括多年生、高度灵活的种植和收获时间以及对各种环境条件的耐受性，这些都为它赢得了当地的名字“抗饥饿树”。以前的研究已经确定了成熟的enset代表家庭粮食安全的战略粮食安全价值，但多部门面板数据集首次确定了更广泛的enset粮食安全关联。我们评估家庭数据的成熟enset面积与四个指标的粮食安全与人口，资产和消费协变量。我们发现，该地区的成熟enset显着提高估计三个四个粮食安全指标，从而提高我们的理解不足的土著作物的作用。需要有一致和可靠的粮食安全指标，以改进监测，特别是稳定性方面的监测。多水平纵向模型的方差分量表明，暴露于特质和协变量干扰影响粮食安全稳定的方式是一致的，作为粮食安全缓冲和积极的适应战略，在面对冲击或变化的enset报告。在这里，我们表明，包括与文化相关的土著作物（如enset）在内的活资产可以提高粮食不安全评估的准确性，这可能会鼓励更广泛地调查与粮食安全和复原力相关的其他农业粮食系统特定资产（如自然价值储存）。
Enset-based food systems are unique to southern Ethiopia where they serve as a staple food for millions of households. Enset, a banana relative of which the entire pseudostem and corm are edible, possesses a highly unusual combination of crop traits including perenniality, highly flexible planting and harvest times, and tolerance of a very wide range of environmental conditions, which together earn it the local name of “the tree against hunger.” Previous studies have identified the strategic food security value of mature enset stands for household food security, but a multisector panel data set makes identifying wider enset food security associations tractable for the first time. We assess whether household data on area of mature enset is associated with four indicators of food security together with demographic, asset, and consumption covariates. We find that area of mature enset significantly improves estimates for three of four food security indicators, thus improving our understanding of the role of understudied indigenous crops. Consistent and reliable food security indicators are needed to improve monitoring, particularly with regard to stability. Variance components of multilevel longitudinal models indicate that exposure to both idiosyncratic and covariate disturbance affects food security stability in a way that is consistent with reports of enset acting as both a food security buffer and an active adaptation strategy in the face of shocks or change. Here we show that living assets comprising culturally relevant indigenous crops such as enset can improve accuracy of food insecurity assessments, which may encourage wider investigation of other agrifood system-specific asset-like natural stores of value associated with food security and resilience.
