Aims
To build towards better understanding of pro-poor sanitation investment practice, and to (potentially) lay the foundation for possible future research around sanitation investment planning in low-income contexts in Bangladesh, Ghana and Kenya.
Findings
The proposed model uses a “source-pathway-receptor” approach: it considers release of pathogens into the environment, transport in the environment, and eventual human exposure.
Next steps
The model can potentially provide a framework for comparing the relative impacts of different sanitation options on health; the next step should be to test the approach in a real city.
A follow-on project is now underway in Dhaka, Bangladesh.
