Generating evidence for investments in sanitation
2016 World Bank Group
The Economics of Sanitation Initiative (ESI) Toolkit attempts to provide a range of sanitation stakeholders with the means to generate relevant evidence on the economic benefits of improved sanitation.
Globally, poor sanitation infrastructure results in costs of over $260 billion a year. Based on methodologies developed by the World Bank’s Water and Sanitation Program (WSP) and implemented widely over the past decade, the ESI Toolkit provides users with a wide array of analyses that can be undertaken individually or in combination to produce results that can be used for different purposes. It allows full-fledged cost-benefit and cost-effectiveness analysis modules to combine results on cost and benefit – thus producing standard indicators that demonstrate socioeconomic return on investment. A powerful sensitivity analysis tool allows users to vary their input data to examine how sensitive results are to uncertainty.
