Meanwhile the World Bank said it there had been bad weather in Sri Lanka's coast and it will get worse with the "accelerating" effects of climate change.
"In Sri Lanka, we recently witnessed the havoc wrought on communities, especially those living on the coast, by extreme bad weather and this could only get worse with the accelerating effects of climate change," said Ivan Rossignol, Acting Country Director for Sri Lanka and the Maldives.
"The World Bank Group is integrating climate risk mitigation into the designs of its investment lending operations to ensure sustainability of projects in Sri Lanka."
The World Bank said it was planning to fund a climate change adaptation program for Sri Lanka, and was already helping with flood control in Colombo.
Though flooding in Colombo has been a long term problem it can now cause much larger losses that in the past with a higher population and a concentration of economic activity.
