When Water Becomes a Hazard : A Diagnostic Report on The State of Water Supply, Sanitation and Poverty in Pakistan and Its Impact on Child Stunting
·
Summary
Written by AI, not yet AICS's view · claude-sonnet-5-5This diagnostic report looks at why child diarrhea and stunting in Pakistan have barely fallen even though poverty has declined and access to water and sanitation has improved. It argues that policy has focused on ending open defecation rather than on the safe management of fecal waste. Water tests found very high levels of E. coli contamination in both surface and ground water. The report urges urgent action on safe sanitation and water treatment.
Key points
- Diarrhea and stunting rates in Pakistan show few signs of decline despite lower poverty, better access to water and sanitation, and much less open defecation.
- Water tests show very high rates of E. coli contamination in both surface and ground water.
- Few households treat their water, and untreated waste water is routinely mixed with surface and ground water to irrigate crops.
- Diarrhea rates remain high even among the wealthiest households in cities like Karachi.
- New research points to environmental enteropathy, in which fecal pathogens damage the intestinal villi of young children and make it hard to absorb nutrients even without diarrhea.
Limitations
Only the abstract is available, so the methods, sample sizes, test locations and the strength of the evidence linking contamination to stunting cannot be judged. The report is a diagnostic assessment and does not test an intervention.
Abstract
Despite a substantial decline in poverty, an increase in access to water and sanitation and a large decline in open defecation, diarrhea and stunting rates in Pakistan show few signs of a decline. This report provides evidence that the policy focus on eliminating open defecation rather than the safe management of fecal waste has been largely responsible for this. Water tests reveal shockingly high rates of E. coli contamination in both surface and ground water. To make matters worse, few households practice water treatment and untreated waste water is routinely mixed with surface and ground water for use in crop irrigation. This multiplies the channels through which the oral transmission of fecal bacteria can occur and creates strong downstream effects through food supplies headed to urban centers. Unsurprisingly, rates of diarrhea have remained stubbornly high even among the wealthiest households in metropolitan cities like Karachi. While the impact of of E. coli on diarrhea is well known, new research is showing the far more damaging impact of environmental enteropathy, a process by which fecal pathogens like E. coli can permanently damage the intestinal villi of young children making it difficult to absorb nutrients, even during periods when the child shows no signs of diarrhea. The report urges urgent action on safe sanitation and the treatment of water to combat this health crisis. (Pakistan)
