It's being called one of the worst natural disasters in the country's history, but international aid for flood-devastated Pakistan has come at a slow pace, especially in comparison to other recent disasters.

The UN has appealed for $460 million in emergency aid for the more than six million Pakistanis that are now homeless due to the recent floods, but less than half of that has been raised.

In comparison, the UN was able to raise $1.2 billion for Haiti in a matter of weeks after the devastating January earthquake there.

Molly Kinder, a policy analyst with the Center for Global Development, says there are three major reasons for the lack of funds for Pakistan; donor fatigue, tight budgets and Pakistan's image problem.

"There is no question that donors are feeling a bit fatigued, both individuals and countries, because the flooding is coming so closely on the heels of these other disasters, the oil spills, the Haitian earthquake," she told CTV's Canada AM Friday morning.

"Donors are also feeling the effects of tight budgets at home and I think it's taken the international community a long time to realize how significant this crisis is."

The flooding comes during a perilous stage for Pakistan's government, as it struggles with the Taliban and al Qaeda within its borders.

"Some of the worst affected areas are some of those that have the most instability," Kinder said.

"If the government is unable to meet the needs of those people in those regions, I think there is a very serious risk of extremists groups taking advantage of that situation."

Pakistan's "image problem" and inability to control large regions within its own borders, is one of the reasons aid has been slow to arrive there. The international community is concerned about corruption and the civilian government's capability to actually deliver the aid to those who need it, Kinder adds.

Analysts say the flooding has strengthened Pakistan's army at the expense of its civilian government.

"The overwhelming majority of Pakistanis have always reposed confidence in the army as compared to elected governments," Mehdi Hasan, a Pakistani political analyst, told The Associated Press. "People feel the army can do better as it is well trained, it has time and the courage to handle any crisis. It gives an edge to the army over civil administration."

About 60,000 Pakistani army personnel are involved in the flood relief operations.

It is expected that rebuilding Pakistan will require billions more in aid.

With the country being nuclear armed and the planned drawdown of NATO troops in Afghanistan, Western leaders may see it as in their best interest to see Pakistan back on its feet as soon as possible.
