Climate change poses a serious challenge to achieving the SDG2 of ending hunger by 2030 and leaves billions of people at risk of food insecurity, illness, and malnutrition. This paper analyzes the long-term impacts of climatic shocks on the nutritional status of 1,911 sample children in Ethiopia. To this end, the study employed a linear mixed effect model, random intercept probit model, and structural equation modeling. Accordingly, climatic shocks are negatively associated with child nutrition. Moreover, early life exposure to climatic shocks is negatively associated with nutritional status at later age. Therefore, if appropriate measures are not taken, the predicted increase in the frequency of extreme events might slow down the secular progress in reduction of child undernutrition in Ethiopia. The role of other covariates was also analyzed. Accordingly, despite their biological and behavioral advantage, girls were more likely to be stunted than boys. This finding highlights the need for a gender-sensitive intervention and the role of intra-household food allocation during shocks. This study also revealed that program participation by drought-affected households has a positive association with child nutrition. Therefore, programs targeted to shock affected households might have a potential to smooth the impact of climatic shocks on child undernutrition Acknowledgement : The data used in this study come from Young Lives, a 15-year study of the changingnature of childhood poverty in Ethiopia, India, Peru and Vietnam (www.younglives.org.uk).
