In many low and middle income countries, schools face limited or unreliable access to safe water, sanitation, and hygiene facilities. Climate change is intensifying water stress through longer dry seasons, erratic rainfall, floods, and contamination of water sources. According to WHO and UNICEF, more than half of schools worldwide lack soap for basic hygiene, while nearly two billion people depend on health and education facilities without basic water services. These conditions directly affect children’s health, school attendance, and learning outcomes, particularly for girls.
