common concepts and terminology for work on natural hazards. The representatives of the World Meteorological Organization (WMO) explained that three of WMO’s programmes, the World Weather Watch Programme, the Tropical Cyclone Programme and the Operational Hydrology Programme, would contribute directly to the scientific data and 2 techniques required for vulnerability analysis. Within these programmes, WMO carried out a project financed by the United Nations Environment Programme (UNEP) in 1974./1975 on the quantitative evaluation of disaster risks from tropical cyclones. The report on this project had been published as WMO Special Environmental Report No. 8. A sequel to this report was a WMO/UNEP project, begun in 1976, to test techniques of flood risk evaluation in 6 countries in Central America, and to plan and implement measures to minimize loss of life and material damage caused by hurricanes. This project was completed in 1978 and had yielded valuable results. In 1979 WMO launched a Hydrological Operational Multipurpose Sub-programme (HOMS) which included a component in flood-risk mapping. The representative of the United Nations Development Programme (UNDP) described the role of UNDP in the field of technical co-operation and the work of the UNDP Offices in de- veloping countries. These Offices acted on behalf of UNDRO in the event of a natural disaster. He added that in the various developing countries, the Resident Representative of UNDP was responsible for 5-year country programmes and was therefore closely concerned with considera- tions of disaster prevention and preparedness. It should be noted that by virtue of a formal agreement between the Disaster Relief Co-ordinator and the Administrator of UNDP, the UNDP Resident Representative was also the UNDRO representative in the field. The representative of the United Nations Centre for Human Settlements (HABITAT) said that the activities of his organization had mainly consisted of technical co-operation with govern-
