The Red Cross and the Secretariat of the Pacific Regional Environment Programme will work together to improve the way weather information is delivered to communities living with the impacts of climate change.
The partnership is just one of 137 climate change or disaster resilience projects registered during the Small Islands Developing States conference in Apia.
A Red Cross climate advisor in Vanuatu, Rebecca McNaught, says the effects of climate change are becoming more evident across the region.
She says the new agreement means more engagement with fishers, farmers and villages who depend on climate information for their livelihoods.
"A partnership with meteorological offices to try and improve early warnings in the Pacific region and working with communities to create action plans on the disaster risks that they face, setting up community disaster committees, so that they can respond. They're often the first responders when disasters happens."
Rebecca McNaught says it has also been creating materials like cartoons to try to bring weather information to a community level.
