Anti-poverty protests have been continuing ahead of next week's G8 summit at Gleneagles.
Protest group G8 Alternatives held what it labelled the "biggest day of political debate and discussion" in Scottish history, in Edinburgh.
Youngsters from all over the world have also been taking part in Unicef's first children's "C8" summit in Dunblane.
Police said Saturday's anti-poverty march in Edinburgh, which attracted about 225,000 people, was trouble-free.
Meanwhile, a small flotilla of yachts, without any protesters on board, sailed into Portsmouth after Bob Geldof's call for boats to bring people over from France to join demonstrations around the summit.
The Sail 8 boats had set sail for Cherbourg from UK ports on Friday but only a handful of vessels reached Portsmouth on Sunday afternoon.
Sail 8 spokesman Don Brind admitted: "It is disappointing. You have to try things. Some work, but others do not, and we have to concede that this didn't.
"Still, being positive, this was a valuable contribution to the Live 8 events," he maintained.
On Saturday, an estimated 225,000 protesters marched in Edinburgh as part of the Make Poverty History campaign as musicians performed in Live 8 concerts around the globe.
The marchers in Edinburgh called for the G8 leaders meeting at Gleneagles from Wednesday to make a commitment to tackle poverty in Africa.
It coincided with the Live 8 concerts in 10 cities around the world, including London.
Lothian and Borders Police paid tribute to the crowd for the trouble-free atmosphere and organisers for their "meticulous planning and co-operation".
On Sunday Chancellor Gordon Brown told the BBC that progress has been made in tackling poverty but it would take more than one G8 meeting to determine Africa's long-term future.
More than 5,000 people were expected to attend eight G8 Alternatives sessions across Edinburgh on subjects ranging from the future of Africa to war and globalisation.
George Galloway is speaking at the G8 Alternatives event in Edinburgh
More than 200 international speakers were due to take part, including Ken Wiwa, son of the executed Nigerian novelist Ken Saro-Wiwa; former Guantanamo Bay prisoner Moazzam Begg; Scott Ritter, former UN weapons inspector and MP George Galloway.
In Dunblane, children from all over the world who have visited Ethiopia with Unicef to see poverty at first hand gathered for the charity's first C8 summit.
Over three days the delegates will draw up a manifesto about issues they think the G8 should address.
A similar event, the J8, was taking place in Edinburgh drawn from pupils from eight schools across the UK.
Hundreds of demonstrators took part in a march organised by the Stop the War coalition from the Mound to Calton Hill in Edinburgh on Sunday.
It was led by the Respect MP George Galloway and culminated in an "Iraq Naming the Dead" ceremony.

Police are concerned about the Carnival for Full Enjoyment, due to be held on Monday, because of the prospect of anarchists disrupting the centre of Edinburgh.
Meanwhile, Live 8 organisers Geldof, Richard Curtis and Bono have written an open letter to G8 delegates urging them to "be great".
"For God's sake, take this seriously - don't behave normally," they write.
"Don't look for compromises."
