India Swachh Bharat Mission — Open Defecation Free

Summary

The Swachh Bharat Mission is one of the largest public health infrastructure programs in history, and its evaluation illustrates the difference between changing physical infrastructure and changing behavior. The RICE Institute evaluation found that toilet construction increased substantially in program villages — but actual open defecation practice among adults declined much less than official statistics claimed. The discrepancy arose because many newly built toilets were unused. Behavior change lagged infrastructure construction. The finding is consistent with a broader literature on sanitation interventions: building latrines is necessary but not sufficient; sustained behavior change requires additional mechanisms including social norm change, enforcement, and convenience. Child health outcomes showed no statistically significant improvement in the first evaluation period.

Research question

"Does a government-led campaign combining toilet construction subsidies with behavior change communication produce sustained open defecation-free communities?"

Methodology

Result

Mixed

Toilet construction: +24 pp in program villages; open defecation practice: no significant reduction among adults (behavior gap); child diarrhea or stunting: no statistically significant reduction

Evidence strength

Moderate

Quasi-experimental design; causal interpretation requires care.

Replication status

Partially replicated
