Mark Boyle of Bristol is walking from Bristol, England to India without bringing or touching any money.
On his 9,000-mile trek to Gandhi's birthplace, he will have to pick his way through war-ravaged Afghanistan.Mr Boyle, 28, said: "I will be offering my skills to people. If I get food in return, it's a bonus"
He says he is part of the freeconomy movement – a group which began in the US and aims to bring about a moneyless society.
He said: "My interest started five or six years ago when I was studying economics.
"The more we accumulate wealth, the more it leads to a breakdown of community."
Mr Boyle aims to walk between 15 and 45 miles a day, with the goal of getting to Porbandar on India's west coast.
The BBC plans to follow Mr. Boyle's walk.
