1. Severity of the Shortage
Extremely low coverage: Only 27% of families in the Sierra have piped water at home, compared to over 97% in nearby cities.
Climate crisis: 64% of the state of Chihuahua is currently facing moderate to exceptional drought—the worst in 40 years.
Unequal access: People in the Sierra consume an average of ≈50 liters per day, while urban populations use 327 liters daily.
2. Everyday Realities
Many Rarámuri and mestizo communities must walk up to two hours to collect water from springs or streams—work that falls mostly on women and girls.
Available water is often seasonal and stored in unprotected containers, increasing the risk of contamination by bacteria and parasites.
3. Social and Health Impacts Impact Recent Evidence Child health 60% of Indigenous children suffer from chronic malnutrition, worsened by record droughts. Waterborne diseases Acute diarrhea is common among children under five, increasing infant mortality. Family economy Up to 80% of homegrown crops fail during dry years, forcing families to buy food and deepening poverty. EducationTime spent collecting water limits school attendance, especially among girls.4. Structural Challenges
Rugged terrain and scattered homes make conventional water networks difficult to install.
Climate change projections forecast a 5–6 °C temperature increase by 2090, further reducing surface and underground water.
Chronic underinvestment and high levels of Indigenous marginalization affect 5,400 localities across 12 mountain municipalities.
5. The Need for Immediate Action
The combination of low access, prolonged drought, and high child vulnerability creates a silent humanitarian emergency. Programs focused on rainwater harvesting, household-level purification, and community education have proven effective: since 2016, over 5,500 rainwater systems have been installed, benefiting more than 22,000 people—but needs far exceed current capacity.
Conclusion
Ensuring access to safe water in the Sierra Tarahumara is key to breaking cycles of illness, malnutrition, and poverty. With support from the GlobalGiving community, we can expand sustainable solutions—such as rainwater harvesting systems and home filters—to reduce collection time, protect child health, and strengthen the resilience of Indigenous communities facing climate change.
