Corrigendum: Every drop matters: combining population-based and satellite data to investigate the link between lifetime rainfall exposure and chronic undernutrition in children under five years in rural Burkina Faso (2022 Environ. Res. Lett. 17 054027)

There was a mix-up in the discussion section of the paper- paragraphs three and four. The age-stratified discussion begins with the sex-stratified topical sentence and vice versa. The Corrected Version is: Second, the nutritional status of children below two years was more likely to be negatively affected by ALE than those aged two or above. This observation can be explained in many plausible ways. The first explanation is that younger children are more vulnerable to rainfall shocks [43], possibly due to weaker immune responses [55] that predispose them to rainfall-related disease effects, which further inhibit dietary intake and nutrient absorption [53]. This is backed by evidence indicating that the most vulnerable period with devastating rainfall effects is between the prenatal and first year after birth [43]. Concerning dietary intake, younger children have higher nutritional needs than older children, making them prone to inadequate dietary supply related to crop failure due to extreme rainfall [52]. Another explanation is catch-up growth. Compared to younger children, older children exposed to different rainfall seasons might experience a counteracting effect; the positive rainfall effect(s) overrides the negative effect(s), resulting in a net positive nutritional effect at the time of measurement. Evidence suggests that children can recover from bad nutritional outcomes related to rainfall in earlier periods [48]. Another plausible explanation for the difference in effects between younger and older children is selective mortality in children. Most child mortality occurs in children under 12 months (around 53% globally and 94% in Burkina Faso in 2020), implying vulnerable children die before 12 months [56]. Thus, the pool of older children might be those better fit to survive despite adverse circumstances, including variations in rainfall quantities. Third, the negative association persisted when we stratified our model by sex, with slight differences between sexes. Some studies suggest that in cultures with a preference for one sex over the other, gender discrimination in intra-household resource allocation may account for the differences in child response to adverse rainfall effects [57, 58]. We found that girls had a less negative impact compared to boys. However, the difference is almost negligible, tending to support evidence from earlier studies [59, 60] showing no gender-based discrimination in intra-household resource allocation in Burkina Fa
