The purpose of this overview on funding flows for the Tsunami is to add value to what is already known. There are a many selective reports on funding flows focusing on one group of donors, or agencies or NGOs which illustrate different parts of the funding picture. In addition, there are some global reports which provide estimates of total funding. This paper will seek to add value by trying to give data which is as reliable as possible and which covers all sources of funding. This requires a painstaking build up of data from a variety of original sources. These can then be validated against each other to minimise the risks of double counting and maximise the prospects of capturing as much of the funding flowing to Tsunami victims as possible.
