摘要

最近从粮食安全的角度衡量了复原力的概念,以估计应对不可预测冲击影响的能力。本研究对埃塞俄比亚中部裂谷梅基河流域农户的恢复能力进行了指数化,并确定了三个kebeles的恢复能力的决定性指标。复原力测量将极端气候、基本服务获取、资产、社会安全网、稳定性、适应能力和社会资本等潜在变量作为复原力指标。采用主成分分析和多指标多原因模型估算弹性能力指数(RCI)。模型表明,资产、稳定性和适应能力对RCI的估计具有显著的解释权重。适应能力与RCI呈负相关,而资产和稳定性对家庭弹性能力有显著的正向贡献。此外,模型还显示,稳定性显著提高了所有研究对象的家庭弹性能力(RC)。此外,在三个kebeles的选定家庭中,Dobena Gola和Dobena Enseno的家庭报告的RC较好,恢复到以前的粮食安全水平。相比之下,雪梨沃的家庭无法抵御冲击和压力。因此,拥有较高RC的家庭可能维持其粮食安全,而那些拥有较低RC的家庭更容易经历粮食不安全。总的来说,研究表明,为了准确估计RC, RCI测量应该在不同的地理尺度和气候带上进行验证。

Resilience capacity among the vulnerable farming households in Meki River catchment, Central Rift Valley of Ethiopia: Present situation and future prospects
The concept of resilience has recently been measured from the food security perspective, to estimate the capacity to deal with the impacts of unpredictable shocks. This study indexed the resilience capacity of farming households and identified determining indicators of resilience across the three kebeles in Meki River catchment, Central Rift Valley of Ethiopia. The resilience measurement considered latent variables such as Climate Extremes, Access to Basic Services, Asset, Social Safety Nets, Stability, Adaptive Capacity, and Social Capital as resilience indicators. Principal component analysis and the Multiple Indicator Multiple Cause model were used to estimate the Resilience Capacity Index (RCI). The model showed that Asset, Stability, and Adaptive Capacity have a significant explanatory weight in estimating RCI. Adaptive Capacity was negatively correlated with the RCI while Asset and Stability showed a meaningful positive contribution to household resilience capacity. Besides, the model revealed that Stability significantly improved household Resilience Capacity (RC) across all the studied kebeles. In addition, among the selected households across the three kebeles, households in Dobena Gola and Dobena Enseno reported better RC to bounce back to the previous level of food security. In contrast, households in Sheliwasho were unable to resist shocks and stressors. Therefore, households possessing greater RC likely sustained their food security, whereas those with lower RC were more prone to experiencing food insecurity. Overall, the study reveals that RCI measurement should be validated across diverse geographical scales and climatic zones for accurate estimation of RC.
