ABSTRACT
The definitions of disaster risk reduction (DRR) and climate change adaptation (CCA) make it evident that they have numerous similarities. DRR's definition embraces the elements of CCA's definition. DRR's inclusion of CCA can be examined further to highlight differences between them. While CCA is about changes to the climate, DRR by definition deals with all environmental hazards and environmental hazard influencers, including climate and its trends, changes, variabilities, and cycles. Pursuing DRR, by definition, means implementing all CCA measures that are needed and often many climate change mitigation measures. Based on basic definitions from Intergovernmental Panel on Climate Change (IPCC) and United Nations International Strategy for Disaster Reduction (UNISDR), DRR includes CCA. Climate change mitigation has been deliberately separated from CCA to a large degree by, more or less, setting up climate change mitigation and CCA as different fields with different institutions, different vocabularies, and different strategies.
