ABSTRACT
Following the reorganization of the WHO in 1998–99, the outcome at headquarters in Geneva is an organizational structure around nine clusters. The cluster concerned mainly with international co-operation on environment and development is the Sustainable Development and Healthy Environments (SDE) cluster. SDE consists of four departments and one special advisory unit (Health and Human Rights). The departments are: (1) Emergency and Humanitarian Action (EHA); (2) Health in Development (HDE); (3) Nutrition for Health and Development (NHD); and (4) Protection of the Human Environment (PHE). For the purpose of this Yearbook, we limit our attention to the latter, which embodies four departments: (a) Water, Sanitation, and Health; (b) Occupational and Environmental Health; (c) Food Safety; and (d) Chemical Safety.
