This is a synthesis evaluation covering the international community's funding of the relief response to the tsunami of December 2004. 1 It is one of five similar thematic evaluations commissioned by the Tsunami Evaluation Coalition (TEC) which was set up to promote a sector-wide approach to the evaluation of the tsunami response and to maximise learning. This synthesis is based on 30 evaluation reports covering bilateral donors, UN agencies, the Red Cross/Red Crescent Movement, non-government organisations (NGOs), funding from the general public, and the local response in the tsunamiaffected countries. The main objectives were to provide an overview of the funding of the response by the various actors, and to assess the appropriateness of the allocation of funds. This report covers only the funding of the tsunami response, not the implementation of the response.
