The World Health Organization–United Nations Development Programme project focuses on reducing the impacts of climate change on cerebral and cardiovascular diseases in four project cities through the implementation of health education and a heatwave and health risk early warning system designed to protect human health. The pro-ject does this with a focus on the following areas of capacity development: (a) data collection; (b) data sharing; (c) early warning system, which combines a city-specific heat wave and health risk early warning system and a multi-level response plan, using novel communication technologies to communicate health risks; (d) communication and cooperation, in the sense that the project is strengthening communication between decision-makers and the public health system; and (e) public awareness.
