The Government pledged up to €300,000 in emergency humanitarian aid today to the South Asian countries worst hit by severe monsoon flooding.
More than 150 deaths have been reported across India, Bangladesh and Nepal - the areas worst hit by the disaster.
Three million people have been made homeless in Bangladesh, while two million have been displaced in the north-eastern Indian state of Assam.
Minister of State at the Department of Foreign Affairs, Mr Tom Kitt, said the Government was closely monitoring the situation and was in contact with partner humanitarian agencies working in the area.
"It is clear that many communities in the region cannot cope with the enormous scale of the monsoon flooding this year," he said.
"The Government's funding is being pledged to meet basic food and shelter needs of those who have lost their homes and livelihoods in Bangladesh, Nepal and India."
The move comes directly after the announcement of a substantial increase in funding to Sudan, bringing the total sent to the crisis-hit west African country to almost €9 million.
Mr Kitt said the €3 million funding increase to NGOs and agencies in the Darfur region, which is thought to be suffering the world's worst humanitarian disaster, had "almost used up all the resources" in the department's emergency funding pot for the year.
But he stressed the Government had made the right move given the urgency of the situation. A Department spokesman added that the emergency funding budget was flexible and money could always be made available for disaster-stricken areas.
More than 800,000 people have been made homeless from the Darfur region after pro-government militias systematically burned villages and destroyed crops and wells in the area.
Up to 30,000 people have been killed in the conflict, many of them civilians and there are fears that at least 300,000 more could die from resulting hunger and disease.
