The recent controversy about the future of skateboarding on the South Bank has prompted the Mayor of London's officials to commission a programme to promote skating, street art and busking.
Greater London Authority officials say they want to "articulate the value of informal culture" and "address misunderstandings".
"The latest tourism research illustrates that unexpected, authentic and immersive experiences are key drivers for prospective visitors to city destinations," says the GLA report authorising the expenditure of £18,000 on the project.
"However, informal culture is often fragile and threatened by a range of factors from development to regulation.
"In the past year, some of Londonís best buskers have been arrested, prompting calls for a change in the law, while the skate park on the South Bank has been threatened with closure, prompting the Mayor to publicly call for it to be preserved.
"Across London informal culture is frequently misunderstood and put at risk."
Southwark Council this summer proposed to introduce licensing and auditions for buskers and street entertainers on Bankside.
