ABSTRACT
Following the reorganization of the WHO in 1998–99, the outcome at headquarters in Geneva is an organizational structure around eight clusters. The cluster concerned mainly with international co-operation on environment and development is the Sus-tainable Development and Healthy Envi-ronments (SDE) cluster. SDE consists of five departments: (1) Emergency and Hu-manitarian Action (EHA); (2) Co-operation and Co-ordination; (3) Nutrition for Health and Development (NHD); (4) Iraq Pro-gramme; and (5) Protection of the Human Environment (PHE). For the purpose of this Yearbook, we limit our attention to thelast of these, which embodies five depart-ments: (a) Water, Sanitation, and Health; (b) Occupational and Environmental Health; (c) Food Safety; (d) Chemical Safety; and (e) Radiation and Environmen-tal Health.
