Estimating Resiliency Benefits of Road Upgradation: Case of the East Road in Malaita, Solomon Islands

Country

The objective of this Paper to estimate the resiliency benefits, in terms of key socioeconomic outcomes, under several road upgradation options and rainfall scenarios. The estimated benefits are compared against 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.
