Council sets up camp site for G8 demonstrators.
A mesh wire fence will surround the campsite on council-owned playing fields in Niddrie.
The mass rallies will be held on July 2 and July 6.
The planned campsite was originally meant to operate from Friday July 1 to 3, the three-day period which spans the Make Poverty History protest which 100,000 people are expected to attend.
But it will now stay open until Friday July 8 to help cope with the influx expected for the Bob Geldof events on July 6.
Officials said the fence would mark the limits of a site which has no other barriers, as well as helping with security and setting routes in and out.
'There will be 24-hour stewarding of the site,' said a council spokesman.
There will be a booking procedure for the site, which will provide toilets, drinking water and temporary lights, but not tents, as Edinburgh council leader Donald Anderson said: 'It is an enormous challenge and we are working around the clock.'
He went on: 'Everyone wants to see a successful outcome for Africa from the G8 and we aim to ensure the debate remains focused on the real issue.'
'While we are doing what we can to ensure the safety of all visitors and residents in Edinburgh, we reiterate our call to everyone who comes to Edinburgh to make sure they have transport and accommodation before they set out.'
Glasgow's council leader, Steven Purcell, said he had instructed the council to be on standby if help was needed in Edinburgh
