The newly established India-UN Development Partnership Fund aims to help island countries become more resilient to extreme weather and other climate change impacts.
The fund said since 1950 extreme weather events in the region had caused more than 9,800 deaths and affected 9.2 million people.
UNDP Pacific is to implement the project in Tonga, Kiribati, the Marshall Islands, Solomon Islands, the Cook Islands, Nauru and the Federated States of Micronesia.
The project involves the provision of technical equipment and training of hydrologists and meteorologists.
