Already more than half of the world’s population lives in urban areas. At present, 35 of these urban centers are considered mega-cities, which have a population of at least 10 million people. It is projected that this number will continue to grow, with the largest number of mega-cities to be found in Asia. Conglomerations of this nature pose major challenges and offer major opportunities to improve health—from waste disposal, nutrition and water supplies, infections disease control, social determinants of health and health care provision, to using social networking and big data analysis to optimize traffic flows. Where can research and innovation add most value to keep cities healthy?
1. Addressing the climate-energy-health nexus in megacities: Innovations from the health sector and beyond
2. ‘Big Data’ in Big Cities: Harnessing information for improving urban health governance and reducing health inequities in mega cities
3. Addressing the challenges of migration and health in megacities: opportunities for research and innovation
4. Life Innovation and Health Care for Better Quality of Life (QOL) in Megacities
5. The built environment in megacities: a new space for innovation, research and design for health
6. "Health in All Policies": enhancing health governance in megacities
7. Health promotion, NCD prevention and control and Sustainable Development Goals: The role of megacities
