Climate change is exacerbating water scarcity globally, particularly in rural areas where women often bear the responsibility for water collection. This study analyzes the impact of rising temperatures on water collection times for 347 subnational regions across four continents from 1990 to 2019. The results show that a 1°C increase in temperature historically increased daily water collection times by 4 minutes. Reduced precipitation also increased water collection times, especially in regions with low precipitation levels or fewer women employed. By 2050, under a high-emissions scenario, daily water collection times for women without household access could increase by 30% globally and up to 100% regionally. This highlights the gendered dimension of climate impacts, which can undermine women's welfare. The study uses fixed-effects regression to control for time-invariant differences and contemporaneous global shocks, providing a quantitative basis for understanding the effects of climate conditions on water collection times. The findings underscore the need for addressing water scarcity and improving access to water resources to mitigate these impacts.Climate change is exacerbating water scarcity globally, particularly in rural areas where women often bear the responsibility for water collection.
