This study employed a multilevel governance approach to understand the manner in which different types of stakeholder networks interact with one another and how their roles should be reinforced. A combination of stakeholder analysis (SA) and social network analysis (SNA) was employed to investigate the perspective of stakeholders in utilizing municipal solid waste (MSW) in agriculture in Hanoi, Vietnam. SA indicated that the local authorities take the main responsibility for the management of MSW in Hanoi. Although other stakeholders express a significant interest in recycling MSW through composting, many of them do not have sufficient power to make any changes to the current system.
