"Developing Asia will need to invest USD 26 trillion from 2016 to 2030, or USD 1.7 trillion per year, if the region is to maintain its growth momentum, eradicate poverty, and respond to climate change (climate-adjusted estimate)," the Manila-headquartered multilateral funding agency said.
The investment needs without adjusting climate change and adaptation costs will be a little less at USD 22.6 trillion, or USD 1.5 trillion per year, through 2030.
In its flagship report 'Meeting Asia's Infrastructure Needs', ADB said regulatory and institutional reforms are needed to make infrastructure more attractive to private investors and generate a pipeline of bankable projects for public-private partnerships (PPPs).
"Countries should implement PPP-related reforms such as enacting PPP laws, streamlining PPP procurement and bidding processes, introducing dispute resolution mechanisms and establishing independent PPP government units," said the report.

"The demand for infrastructure across Asia and the Pacific far outstrips current supply," said ADB President Takehiko Nakao.
"Asia needs new and upgraded infrastructure that will set the standard for quality, encourage economic growth, and respond to the pressing global challenge that is climate change," he added.
As per the ADB report, the region currently invests about USD 881 billion in infrastructure (for 25 economies with adequate data, comprising 96 per cent of the region's population).
The infrastructure investment gap, which is the difference between investment needs and current levels, equals 2.4 per cent of projected GDP (climate-adjusted) for 5 years from 2016 to 2020.
"Public finance reforms could generate additional revenues estimated to bridge around 40 per cent of the gap (or 2 per cent of GDP) for these 24 economies," the report added.
