Severe Tropical Cyclone Pam barrelled into the archipelago a week ago, bringing sustained winds of some 155 miles per hour which devastated entire communities.
    
"Around 166,000 people, more than half of Vanuatu's population, have been affected by Tropical Cyclone Pam on 22 islands," the Office for the Coordination of Humanitarian Affairs (OCHA) said in a situation report.

"Food stocks and water reserves are being exhausted and will not last more than a couple of weeks across the affected islands."
    
The agency said the confirmed death toll had risen to 16, as aid workers were able to reach new areas, with completed assessments covering 15 islands.
    
Aid agencies have stressed that potable water, food, shelter and health were a priority in the aftermath of the storm which hit late on March 13.
    
The latest assessment found damage to food crops was extensive. "Coconut and banana plantations have been particularly devastated, which will have significant longer-term impact," OCHA said, noting that most people living on the outer islands grow their own food.
    
In some areas local residents would not only lose their main source of income due to damage to crops such as copra, but their food security would be threatened by the loss of livestock, such as pigs and poultry, it said.

In its situation report, OCHA said that access to some communities was still hindered across the sprawling nation which is made up of more than 80 islands.
    
But it said between 50 and 90 percent of local dwellings were estimated to have been damaged by the fierce winds which pounded Vanuatu as the eye of the storm hovered over the nation for hours.

"Around 65,000 people are in need of temporary emergency shelter," it added. Aid agencies have mobilised to help the country, and are on the ground distributing food, water and health services but access to drinkable water is a concern after ground water sources were contaminated by the storm.
    
Schools have been postponed for two weeks, and are due to restart on March 30, with OCHA estimating that 500 schools were damaged, something which will affect up to 70,000 children.
    
The agency said fuel stocks were running low across the affected islands while electricity was mostly unavailable and generators are essential.
