Recommendation F of the World Health Organization (WHO) working group preparing for the London Health and Environment Conference (June 1999) advocates orientating the activities of bilateral and international donor agencies and other interagency bodies to provide resources and technical assistance to countries in need, for the implementation of both mitigation and adaptation strategies. These strategies should be designed to reduce the short- and long-term health impacts of climate change, fossil fuel combustion and stratospheric ozone depletion.
