"I stand to appeal on behalf of the government and people of Vanuatu to the global community to give a lending hand in responding to these very current calamities that have struck us," Baldwin Lonsdale said in Sendai, Japan at the Third UN World Conference on Disaster Risk Reduction.
Late Friday, category 5 tropical cyclone Pam swept through the republic's capital Port Vila, claiming, according to the UN Office for the Coordination of Humanitarian Affairs (OCHA), the lives of at least 44 people.
Earlier in the day, the United Nations Children's Fund (UNICEF) reported that at least half of population of Vanuatu, including almost 54,000 children, may be affected by the disaster.
UNICEF New Zealand Executive Director Vivien Maidaborn said in a statement on Saturday she is concerned the cyclone may "potentially be one of the worst" in the history of the Oceanic nation.
