This document discusses ecosystem-based solutions for disaster risk reduction and climate change adaptation. It raises questions about quantifying ecosystem services for erosion reduction and the economic costs and benefits of "green" versus conventional infrastructure. The document also discusses strategies for managing uncertainties, noting the links between ecosystems and hazards like landslides, flooding, coastal hazards, and how vegetation can help mitigate these. Hybrid green/gray infrastructure and the multiple benefits of ecosystem-based approaches are presented. The document advocates increasing scientific knowledge, capacity building, and policy around ecosystem-based disaster risk reduction and climate change adaptation.
