Economic Assessment of Sanitation Interventions in Southeast Asia: A Six Country Study Conducted in Cambodia, Indonesia, Lao PDR, the Philippines, Vietnam and Yunnan Province (China) under the Economics of Sanitation Initiative, 2015. Water and Sanitation Program.
Excerpts: The present study has presented evidence on the costs and benefits of sanitation improvements in different programmatic and geographical contexts in Southeast Asia. This evidence enables explicit comparison of sanitation options on the basis of their relative merits and thus informs both public and private decisions on sanitation investment.
The high socioeconomic returns of sanitation investment indicate that it should be promoted as a central development priority. The economic evidence generated in this study has demonstrated the importance of improved sanitation for a number of development outcomes, including public health, the natural environment, education, economic development, social outcomes, gender equality, and poverty alleviation. Improved evidence on the costs of sanitation and those potentially willing to pay for it, gives an evidence base for sanitation planners and providers on which to estimate the market size for sanitation goods and services.
