The rubble of crumbled buildings still lines the streets of Port-au-Prince, a year after a devastating earthquake levelled the Haitian capital and left more than 230,000 people dead.

Bodies are still being pulled from the rubble, which piled up in the aftermath of the Jan. 12, 2010 quake.

Ninety-five per cent of the quake-related debris remains on the ground and that has left hundreds of thousands of Haitians unable to return to their homes.

So many remain living in camps, which the U.S.-based RAND organization reports is likely to remain the case for this year's hurricane season.

Living conditions in some of the temporary camps have been described by observers as a humanitarian disaster. One recent United Nations report said that incidents of rape are on the rise. Other reports point to the growing influence of marauding criminal gangs.

The limited progress is distressing for the aid agencies, governments and other donors that have pledged billions to rebuild Port-au-Prince.

There a number of reasons for the slow clean-up, said Philip Oxhorn, a professor at McGill University and founder of theInstitute for the Study of International Development.

"Part of it is no one's setting priorities. Part of it is that people would rather build schools than do the nitty-gritty of moving the rubble out -- it's not sexy or attractive enough," he said.

"What's missing is the willpower to say, ‘Look, we've got to move the rubble out, we've got to decide who owns the land because that's another big issue, and start doing the basics."

CTV's Tom Walters reported that while billions of dollars of support have been scrawled on paper, those donations have not drawn the results they should in Haiti.

"You hear agencies saying that money has been allocated for work -- that's a very different thing than actually spending it on the ground," Walters said from the Haitian capital on Tuesday. "What we're seeing here is a society that looks very little different than it did a year ago."

In a recent report, the aid group Oxfam scolded the foreign organizations and governments for their shortcomings on the ground.

Foreign governments have not done enough "to support good governance and effective leadership in Haiti," Oxfam said in the report.

At the same time, the aid agencies on the ground "continue to bypass local and national authorities in the delivery of assistance, while donors are not coordinating their actions or adequately consulting the Haitian people."

The delivery of aid money has been a problem, too. Ten months ago, international donors pledged more than $5.3 billion that was earmarked for a period of 18 months.

More than $3.2 billion in public funding is still owed to the Caribbean country, according to former U.S. President Bill Clinton's UN Office of the Special Envoy to Haiti.

As recently as Tuesday, Ottawa announced that it plans to spend $93 million to help boost things like health programs and agriculture there. That money will be drawn from the $400 million the federal government pledged to Haiti last year.

While much of that aid money has failed to materialize so far, the mood on the ground in Haiti remains mixed, according to Emmanuel Isch, vice-president of international and Canadian programs at World Vision.

"We find people that are still optimistic about the future but at the same time they're tired of the situation they find themselves in," Isch said. "They're expecting more of their government, they're expecting the ability to take on and move on with their lives."

Haitian Prime Minister Jean-Max Bellerive told The Associated Press that he is surprised by the slow delivery of funds to his country.

He said that it could be possible that some donors are waiting for the presidential election matters to be settled before acting on their commitments.

"Perhaps some donors say, 'Let's wait until we know exactly who will be there for the next five years,"' he said.

Preval is scheduled to leave office early next month. He has been blamed by many observers for the lack of leadership in Haiti.

It is still not clear who will succeed Preval, after a recent election was marred by fraud and the results are still being analyzed by election officials. Haiti could see a second-round of voting take place with a provisional government installed in the interim -- a plan that Preval has said he is adamantly against.

Oxhorn, of McGill University, said the lack of infrastructure in the Caribbean country has made it difficult to spend on the scale required for rebuilding cities. But the disputed election has made matters worse.

Haiti suffers from "a week government lacking in personnel and lacking in credibility and legitimacy, who's making decision on where the money should go."

The result, he said, is that foreign money pledged for reconstruction "just stays in the banks."
