Over half of the world's population currently live in urban areas. Although the global population growth rate is declining, the global population is increasing and is expected to reach 9.6 billion by 2050, with an estimated 70% living in towns and cities. This growing population will create more demands on an increasingly stressed planet with limited resources. It will be cities and the associated industrial and commercial activities that will demand the majority of the 40% increase in world energy forecast by 2030. It will be cities that will demand the majority of the 70% increase in food forecast by 2025. It will be in cities where the growing middle classes will be the main consumers of electricity, oil, food beverages, household appliances, cars and other goods and service. This is a potential recipe for continued poor air quality and illustrates the importance of integrated multi-stakeholder strategic planning and coordinated management.
