Tsunami mess

Six months after the tsunami, the usual bickering among donors, UN and recipient governments' politics and corruption is hindering the aid program. The BBC points out:

Failure to deliver assistance effectively to the poorest, or to plan properly for the future, reveals fundamental weaknesses in the system.

In Banda Aceh, for instance:

The head of Aceh's rebuilding programme, Korro Mangusubroto, has admitted: "Only one per cent of the money has been spent.
…
Rebuilding was delayed while the Indonesian government dithered about how to spend the aid, but now restrictions have been lifted.

The UN is complaining that some donors are reneging on their pledges (why the UN announces pledges instead of the amounts of money it effectively receives is beyond me). On a total of 5.32 billions dollars (not taking into account considerable private donations), only 3.46 have been allocated; however, have the UN aid agencies the capacity to utilize such an unprecedented amount of funds? There is an interesting table on a UN site that shows how the Flash Appeal funds have been distributed among the agencies; the total is only $321,543,721. Furthermore, although this amount is indicated as "expenditure", it indicates earmarked funds for future expenditure. A "delivery against budget" would illustrate the progress of the aid program much better.
