Estimating resiliency benefits of road upgradation: Case of the East Road in Malaita, Solomon Islands

Governments and their multilateral partners are increasingly recognizing the importance of incorporating climate and disaster resilience considerations into infrastructure development plans as well as the related construction and financing decisions. The objective of this paper to estimate the resiliency benefits, in terms of key socioeconomic outcomes, under several road up-gradation options and rainfall scenarios. The estimated benefits are compared to the related lifecycle costs to inform investment decisions. The analysis is based on the methodology developed by the World Bank and Kyoto University to operationalize and measure key infrastructure resilience concepts at the project level. The East Road in Malaita in the Solomon Islands is used to pilot this methodology and examine its applicability.
