Heat pushes girls out of school first.
The data on this is now unambiguous.
Dropout risk
Girls leave when school closes — and rarely return
UNICEF (2025) explicitly states: "Girls are often disproportionately affected, facing increased risks of dropping out of school and gender-based violence during and after disasters." Heatwaves were the #1 climate hazard closing schools in 2024. In Kenya, drought forced families to "sacrifice education, especially that of girls." In South Sudan, a single March 2024 heatwave closed all schools nationwide, affecting 2.2 million students — and UNICEF confirms girls face heightened dropout and GBV risk after every such closure. A 2026 Springer/Climatic Change study across 122 developing countries confirms heat reduces secondary enrollment significantly more for girls than boys.
School as protection
Keeping girls in school is what protects them from everything else
A Kenya study (BMC Public Health, 2022) found girls experiencing school closures had 3× the risk of school dropout and 2× the risk of pregnancy compared to peers whose schools stayed open. During Sierra Leone's Ebola school closures, teenage pregnancy rates doubled and girls' secondary schooling dropped from 1.8 to 0.9 years. Extended heat closures increase the likelihood of child marriage, transactional sex, and early pregnancy — all of which make return to school nearly impossible. School being open and bearable is the intervention. Everything GFH builds serves this.
Economic burden
260% more heat-related losses — women vs men
The Arsht-Rock "Scorching Divide" report (Atlantic Council) found that when unpaid domestic labour is included — the burden of which falls disproportionately on women and girls — heat-related economic losses for women are 260% higher than for men. Heat forces girls home to care for sick relatives, compounding their own learning loss with invisible domestic labour. Girls pulled from school also enter the informal sector — the most heat-exposed, least-protected form of labour — with no route back. By 2050, extreme heat could claim 204,000 women's lives annually across just India, Nigeria and the US.
WASH barrier
No water + 38°C = girls stay home
42% of schools in low- and middle-income countries lack basic water services (WHO/UNICEF JMP 2023). In extreme heat, this is not a hygiene inconvenience — it is a direct barrier to attendance. Girls managing menstruation without clean water and private facilities in 38°C+ heat routinely stay home. Heat resilience programmes that do not address water access are solving half the problem. Our platform's hydration infrastructure and water bell system directly targets this gap.
Return on investment
25% earnings uplift per year of girls' secondary school
An additional year of secondary education for a girl raises her future earnings by 25% — significantly higher than the already-strong 8–10% average return for all children (World Bank 2022). Heat-driven dropout concentrates its economic destruction on the highest-return educational investment available to any government or funder. Maternal complications are the leading cause of death for girls aged 15–19 globally — and girls who stay in school are significantly less likely to face early pregnancy. Protecting girls in school during heat events is among the highest-ROI climate adaptation interventions that exist.
The framing gap: Every climate education and school resilience programme treats heat as a universal problem. It is not. For girls, school closure caused by heat is not just an educational disruption — it is the trigger for a cascade of harms: early marriage, pregnancy, GBV, informal sector labour, lost lifetime earnings, and higher maternal mortality. A
UN study (April 2025) found the climate crisis is driving a surge in gender-based violence directly linked to heat and displacement. Keeping school open, safe, and bearable is the single most effective intervention available — and it's what GFH builds. Sources:
