Integrated water resources management (IWRM) combines land and water management through broad-based stakeholder participation to realize multiple co-benefits in watersheds. IWRM recognizes the economic benefits of managing water and related resources in an integrated manner to provide high levels of ecosystem services (ES). In turn, ecosystem management incorporating ES valuation and management is an increasingly popular and useful means of achieving IWRM goals as well as other socio-economic and environmental benefits.
