Impact of Ethiopia’s 2015 drought on child undernutrition
利用2015年埃塞俄比亚干旱前后的全国代表性数据，研究发现干旱并未普遍导致儿童营养不良增加，但在道路网络有限的受灾地区，慢性营养不良率上升，表明道路基础设施投资有助于增强抗旱韧性。
In 2015, Ethiopia experienced one of its worst droughts in decades. Using nationally representative data from before and after the event, we do not find evidence that this drought led to widespread increases in chronic or acute child undernutrition. However, further analysis indicates that chronic undernutrition rates did increase in drought-exposed areas that had a limited road network. This finding suggests that the recent investments in road infrastructure in Ethiopia may have contributed towards better resilience against droughts.
