A significant component of the project involves the climate proofing of coastal roads and those passing through highly mountainous agricultural areas to adapt to rising sea levels, rising temperatures, and worsening erosion from flooding. A “no-regret” approach to climate proofing was taken to minimize the country’s vulnerability to the adverse effects of climate change while minimize other risks to the road sector.
Based on assessment results, the project team proposed engineering and bioengineering adaptation measures, including constructing earth levee banks with “rip-rap” protection for roads at risk of erosion from extreme waves along the coastline and reforestation or revegetation of unstable slopes in the mountainous agricultural areas, among other measures. The project cost increased by about 10% with climate proofing measures, but the measures strengthen the project design. Because of the climate change assessment, the 230 kilometers of roads to be rehabilitated by the project will be less vulnerable to the impacts of climate change. It will not harm or increase the vulnerability of surrounding regions and will provide added co-benefits to surrounding communities.
