PDC uses information, science, and technology to enable effective evidence-based decision making and to promote disaster risk reduction (DRR) concepts and strategies. The Center provides multi-hazard warning and decision support tools to facilitate informed decision making and critical information sharing, supporting appropriate and effective actions. PDC also conducts advanced risk assessments that integrate hazard exposure with socio-economic factors for vulnerability and capacity, so the disproportionate impact on populations can be better understood, and then mitigated through improved preparedness and planning processes.
