Cost-effectiveness of disaster risk reduction and adaptation to climate change

Climate change adaptation (CCA) and disaster risk reduction (DRR) have similar aims and mutual benefits. Strengthening CCA through effective DRR is a new research interest in the fields of climate change and disaster risk science. This review presents estimates of the cost-effectiveness of CCA interventions and DRR interventions through the conventional economic measurement of cost-benefit analysis (CBA).1 It focuses on CBA as there is significant literature on this in relation to DRR and CCA, and little could be found on values from other economic measures (as is highlighted by Mechler, 2016).
