我们结合回顾生育率调查(DHS)和气候模型再分析(ERA-40)的高分辨率数据,估计了随机天气波动过去如何影响28个非洲国家的婴儿死亡率。我们发现,在疟疾流行地区,婴儿在宫内暴露在比正常情况下更长的疟疾持续时间,以及在干旱地区,特别是在饥饿季节出生时,婴儿更有可能死亡。根据这些估计,我们预测1981年至2000年和2081年至2100年,由于极端天气事件和流行地区的母婴疟疾,非洲婴儿死亡总数。
We estimate how random weather fluctuations affected infant mortality across 28 African countries in the past, combining high-resolution data from retrospective fertility surveys (DHS) and climate-model reanalysis (ERA-40). We find that infants were much more likely to die when exposed in utero to much longer malaria spells than normal in epidemic malaria regions, and to droughts in arid areas, especially when born in the hungry season. Based on these estimates, we predict aggregate infant deaths in Africa, due to extreme weather events and to maternal malaria in epidemic areas for 1981-2000 and 2081-2100.
