[1] The alliance and its members work in favour of the healthy city, defined by the World Health Organization (WHO) as "one that is continually creating and improving those physical and social environments and expanding those community resources which enable people to mutually support each other in performing all the functions of life and in developing to their maximum potential".
[2] The first international declaration that promoted the concepts underlying healthy cities, the Alma Ata Declaration, was adopted at the International Conference for Primary Health Care, jointly convened by the WHO and UNICEF in Almaty (formerly Alma-Ata), presently in Kazakhstan, 6–12 September 1978.
Trevor Hancock and Leonard Duhl promoted the term "Healthy Cities" in consultation with the WHO:[5] Economic development has brought comfort and convenience to many people in the industrialized world, but in its wake are pollution, new health problems, blighted urban landscapes and social isolation.
In an effort to remedy these ills, people from disparate backgrounds in thousands of communities are joining together with government agencies under the Healthy Cities/Healthy Communities banner to improve the quality of life in their towns and cities.At the First International Conference on Health Promotion in 1986, the Ottawa Charter for Health Promotion was adopted that presented actions to achieve healthy life for all people by the year 2000 and beyond.
[6] Following a second international conference on health promotion at Adelaide in 1988 and a third at Sundsvall in 1991, and twenty years after the Alma Ata Declaration, the Fourth International Conference on Health Promotion held in July 1997 in Jakarta adopted the new Jakarta Declaration: "New Players for a New Era - Leading Health Promotion into the 21st Century".
