In an attempt to harness the climate change effect on vulnerable groups in developing countries, the Asian Development Bank (ADB) designed a program that provides loans for households in Dong Hoi, Vietnam to build biogas digesters to deal with climate change-related risks. This project aimed to evaluate the impact of increasing the density of eco-toilets and biogas digesters on sanitation, health condition and household incomes in Dong Hoi. A survey was conducted for 1,000 households in Dong Hoi; data collected was used for project impact evaluation.
