GOVERNMENTs must act today to ensure that the infrastructure needed in 2020-2030 will be planned, developed and operational in time, according to an OECD report.The report titled Strategic Transport Infrastructure Needs to 2030   says that air passenger traffic could double, air freight could triple, and port handing of maritime containers worldwide could quadruple by 2030. The OECD estimates USD 53 trillion of investment, equivalent to an annual 2.5% of global GDP,  will be needed to meet demand over the coming decades. Over USD 11 trillion of that will be required for ports, airports and key rail routes alone. Increased private-sector investment in strategic transport infrastructure will be essential, says the report.The report says that though upgrading key infrastructure will drive competitiveness, boost trade and promote economic growth ,new ways of financing are needed as the traditional model of public funding for major projects is likely to dry up.
