Many NGOs were already working in Tsunami affected areas when the tragedy struck. They moved immediately to respond to the humanitarian disaster. As the one-year anniversary of the Tsunami approaches, professional NGOs are looking to take stock of their response. CONCORD (European NGO Confederation for Relief and Development) and VOICE (Voluntary Organisations in Cooperation in Emergencies) wish to take this opportunity to describe how NGOs reacted to the Tsunami, what projects they are implementing and what lessons they have learned in the extraordinary circumstances of this disaster. They also wish to put forward some institutional and political recommendations to the European Union (EU), to ensure a sustainable recovery for the populations affected by the Tsunami.
