The former UN special envoy for HIV/AIDS in Africa accused the G8 Sunday of abandoning its commitments to health and social equality in Africa, suggesting its leaders are having trouble finding their "moral anchor."

The leaders of the world's top industrialized nations have reneged on promises to have-not nations, particularly those in Africa, to help improve the health, social and equality conditions in those countries, said Canadian Stephen Lewis.

Last week, at a summit in Heiligendamm, Germany, the G8 leaders announced a $60-billion US commitment to fight disease in Africa, but Lewis said that funding did not come with a timeline.

Lewis said the leaders only committed the funds "over the coming years."

"What in the world does that mean?" Lewis asked.

The G8 countries are spending $120 billion annually to deal with conflicts in Iraq and Afghanistan, but they can't find half that amount to deal with HIV/AIDS, Lewis said.

Angers rock stars Bono, Geldof

"What has happened to the moral anchor of this world?" he asked.

The G8 announcement also angered rock-star anti-poverty activists such as Bono and Bob Geldof.

Bono said Canada was among the nations blocking aid for Africa.

He described Prime Minister Stephen Harper as out of step with Canadians who enjoy a prosperous economy and surplus public finances and would like to help others.

Harper countered by saying that when it comes to aid money "the full framework of accountability" is very important.

He also hailed the G8 agreement for declaring that the bulk of countries receiving aid should meet the standards of good governance, accountability and democracy.

'Abiding nightmare of the pandemic'

Lewis also told the conference that the G8 is deficient in dealing with gender equality, an issue that he said drives pandemics in Africa.

"It is the abiding nightmare of the pandemic," Lewis said. "There is a terrifying spectre of carnage among the women."

He said the single most important struggle on the planet is the struggle for gender equality.

"You cannot continue to marginalize 50 per cent of the population of the planet and expect to realize a modicum of justice."

Lewis made the comments to the International Health Promotion Educators conference in Vancouver.

More than 3,000 people are attending the conference June 10-15, which is held every three years to review and critically assess health promotion's progress and chart courses to deal with health issues.
