Asia Pacific's costly climate threat
The Asia-Pacific region has been warned it needs to spend about $40 billion a year to "climate-proof" its countries' economies against the impact of global warming.
The Asian Development Bank's vice-president, Bindu Lohani, says that will allow countries to undergo "transformational change" to build resilience to climate change disasters.
Dr Lohani made the comments at the Asia-Pacific Climate Change Adaptation Forum in Bangkok.
The event was cancelled last year after Thailand suffered its worst floods in half a century.
The floods killed more than 800 people and inundated hundreds of thousands of homes.
Dr Lohani warned there will be more such frequent natural disasters and they will complicate the challenge of achieving sustainable development in Asia.
He says the money could be used for infrastructure, along with better mitigation and adaptation practices.
