【 摘 要 】

Governments and their multilateralpartners are increasingly recognizing the importance ofincorporating climate and disaster resilience considerationsinto infrastructure development plans as well as the relatedconstruction and financing decisions. The potential medium-and long-term benefits of increased resilience must beconsidered alongside short-term costs of resilient designand implementation. The objective of this paper to estimatethe resiliency benefits, in terms of key socioeconomicoutcomes, under several road upgradation options andrainfall scenarios. The estimated benefits are comparedagainst the related lifecycle costs to inform investmentdecisions. The analysis is based on the methodologydeveloped by the World Bank and Kyoto University tooperationalize and measure key infrastructure resilienceconcepts at the project level. The East Road in Malaita inthe Solomon Islands is used to pilot the this methodologyand examine its applicability. The parameters selected tomeasure resiliency are based on the key benefits the roadprovides to the people living around it: economic benefitsproxied by travel time, access to hospitals, and access tomarkets. Due to data constraints in Malaita, the report isbased primarily on expert inputs and geo-spatial data. Itconsiders mainly technical improvements to road upgradationthat might impact resiliency.
