UNHaRMED framework report: a co-creation approach for the development and use of decision support systems for disaster risk reduction

This report proposes a generic approach for the development and use of decision support systems (DSSs) for disaster risk reduction (DRR). At the core of the DSS is an integrated model, consisting of a land use model and risk models for four hazards, including flooding, coastal inundation, bushfire and earthquake. The inputs to these models are affected by a number of external drivers that change over time, including demographics, climate change and economics, as well as a number of mitigation options, including spatial planning, land management, structural measures and community-based resilience efforts. The outputs from the integrated model include risk maps for the individual hazards that change over time, as well as cost-benefit, social and environmental indicators used for assessing the impact of risk reduction portfolios.
