A United Nations report says nearly a million people are in need of food assistance in the south-eastern Philippines.
It says they are still suffering the effects of being displaced a month after powerful Typhoon Bopha devastated the region.
The typhoon has killed more than 1,000 people and left more than 800 others missing.
Philippines social welfare officials and the World Food Program say food packs have been distributed to 238,000 people, and school feeding programs will be launched to meet the needs of those requiring assistance.
The United Nations Office for the Coordination of Humanitarian Affairs reports only a fifth of the UN's appeal for $US65 million in aid has been met.
The governor of the Philippines province of Albay, Joey Salceda, says countries whose greenhouse emissions caused climate change should bear a larger responsibility for its victims.
The province is regularly hit by storms and he has decried the slow international response.
