By International Institute for Environment and Development (IIED), 2001 The Four Rs is a tool which can be used to clarify the roles played by different stakeholders and the nature of relationships between them. Assessment and negotiation amongst stakeholders of these roles and relationships is necessary before developing the capacities needed for improving policies and institutions. The Four Rs tool aims to operationalize the concept of "roles" by unpacking these into rights, responsibilities, revenues (benefits) of stakeholders, and the relationships between stakeholder groups. This is particularly useful in contexts where roles need re-thinking, negotiating and developing.
