La Niña and Infrastructure
When Vanuatu experiences heavier than normal rainfall, PWD
infrastructure project activities get delayed, says VanKIRAP’s
Infrastructure Sector Coordinator, Raviky Talae.
He says heavy rainfall events also have “huge cost implications” for
PWD, “and lots of effort must then go into reprioritising projects”.
“La Niña extreme rainfall events affect accessibility, as they can cause landslides and temporary relocations of infrastructure”.
“Infrastructure projects need favourable weather to meet their deadlines
and stay within budget. Because this is the third La Niña in a row,
the higher than average rainfall it will bring may reduce the
design life of infrastructure and make roads and bridges even more
vulnerable to damage”, says Raviky.
“Vanuatu’s road infrastructure has already been pushed beyond the
normal maintenance cycle and budget by the previous two La Niñas, says Raviky.
regardless of the conditions, "PWD will continue to adapt, plan and
implement infrastructure projects according to the climatic conditions”,
