The practice of protecting the environment and health is changing. While some states continue to adopt the traditional regulatory approach of seeking to monitor and control risk, elsewhere environment and health (EH) agencies at national, regional and local levels have become oriented towards preventing and reducing risk. This cannot be done through regulation alone but requires a multi-partner approach, with each being prepared to contribute towards reducing a prevailing level of risk. This invariably involves a higher degree of coordination and communication but can lead to greater and more sustainable improvements in EH status.
