This chapter assesses community participation in the Mekong River Delta, Vietnam, by
calculating willingness to pay for a source-separated municipal solid waste (MSW) improvement
program. The urbanization level was used to stratify the data. This article employed both
contingent valuation methodology (CVM) and choice experiment (CE) to determine the accurate
willingness-to-pay (WTP) values and to validate the methodologies utilized. Welfare benefits
examined in both approaches suggest that MSW improvement programs be implemented in
developing countries. The findings indicate that community participation may be a viable option
for resolving environmental issues associated with MSW management. The findings also show
that households care about various attributes related to environmental protection, such as
recycled, organic, and residual. Interestingly, households in less developed areas are more eager
to participate and pay a higher price for the improvement program. Given that both approaches
generated consistent values, future research employing these methodologies should be conducted
to provide information to policymakers on various non-market-related issues.
