The IHRC was created in the devastating days and weeks after the quake, and its two-year mandate expired in October. Since then, new reconstruction programs have virtually stalled.

However, the U.N. Office for the Coordination of Humanitarian Affairs reported progress in clearing tent cities that sprang up after the quake. It said tent dwellers have declined from 1.5 million to 370,000. But concerns linger about quake victims who continue to live in precarious conditions as reconstruction drags.

This week, the United Nations Office of the Special Envoy for Haiti reported that a little more than half of the $5.33 billion pledged by donors to help rebuild Haiti had been disbursed.

There has been a significant drop in aid post-2010, down from an estimated $4 billion in 2010 to $438 million so far this year.

According to an analysis of the pledges, only 10 percent of the funds actually went directly to the Haitian government.

“In countries like Haiti that are most reliant on foreign aid, donors often avoid investing directly in the government, wary of perceived levels of corruption and institutional incapacity,’’ said Deputy U.N. Special Envoy Paul Farmer. “Such legitimate concerns should not preclude investment in important public institutions, but rather should be linked to investments in technologies and systems that might enable the government of Haiti to be accountable, both to its own citizens and to its donors.’’

Still, some are hopeful that funds and reconstruction will increase as donors’ confidence in the government grows.

“A lot of long-standing decisions have been taken in the last few weeks that have allowed a number of activities to move forward,” said Hasan Tuluy, World Bank vice president for Latin America and the Caribbean.

Officials of the World Bank are seeking approval from their board for a two-year Haitian strategy that will focus more on long-term sustainable programs.

“We have seen substantial progress” in Haiti, Tuluy said, but added, “much more needs to be done to accelerate the reconstruction.”

Martelly’s speech stayed within the theme of promoting peace and dialogue that was highlighted by most leaders who spoke Wednesday at the General Assembly.

“The establishment of the Untied Nations gave our people the hope that things could be different. We cannot let those hopes die,” he said.
