World Health Organisation (WHO) suggests that, among other things, a ‘healthy city’ must have: 

• A ’Clean’ and ‘Safe’ environment.
•  Meets the ‘Basic Needs’ of ‘All’ its inhabitants. 
• Provides easily accessible ‘Health’ service.
• Increasing ‘Shelter’ for the urban poor.
•  Provision of basic urban services such as ‘Education’, ‘Primary Health care’, ‘Clean Water and Sanitation’.
•  Improving women’s access to ‘Basic Services’ and government facilities.
•  Upgrading ‘Energy’ use and alternative ‘Transport’ systems. 
• Reducing ‘Air Pollution’
