| Summary: | 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 potential medium-
and long-term benefits of increased resilience must be
considered alongside short-term costs of resilient design
and implementation. 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 the this methodology
and examine its applicability. The parameters selected to
measure resiliency are based on the key benefits the road
provides to the people living around it: economic benefits
proxied by travel time, access to hospitals, and access to
markets. Due to data constraints in Malaita, the report is
based primarily on expert inputs and geo-spatial data. It
considers mainly technical improvements to road upgradation
that might impact resiliency. |
