The World Health Organization has confirmed that cities play a critical role in enhancing global health, noting that more than half of the world's population currently resides in urban areas, with expectations that this number will rise to approximately 70% by 2050.
During the Healthy Cities Summit held in Rio de Janeiro, Etienne Krug, Director of the Department of Social Determinants of Health and Promotion at the organization, stated that cities possess a unique ability to respond quickly and effectively to public health challenges. Local leaders are often closer to their communities than national governments, facilitating the implementation of evidence-based interventions.
Event Details
In his remarks at the summit, Krug pointed out that "a city is more agile than a large country and can respond faster," adding that some national governments no longer prioritize health to the same extent. Discussions focused on the importance of preventive policies targeting the main risk factors for non-communicable diseases and injuries, such as tobacco use, unhealthy diets, air pollution, high temperatures, and unsafe roads.
He also emphasized that prevention is more cost-effective than treatment, highlighting the high costs associated with managing diseases such as cancer, diabetes, and cardiovascular diseases, along with the long-term care required for victims of road accidents.
Background & Context
The Healthy Cities Summit is a prominent event that brings together over 200 public health and city leaders from 55 cities worldwide, alongside journalists from various countries. The summit was organized by Bloomberg Philanthropies, the World Health Organization, Vital Strategies, and the city of Rio de Janeiro.
This summit aims to enhance collaboration among cities to combat non-communicable diseases, improve food safety in schools, address overdose cases, and reduce injuries from traffic accidents. It was emphasized that up to 80% of these cases can be prevented.
Impact & Consequences
Traffic-related injuries are a major issue, claiming the lives of approximately 3000 people daily, making them the leading cause of death among individuals aged 5 to 29 years. City-led policies have shown tangible results, including an increase in life expectancy, driven by local efforts to address non-communicable diseases and injuries.
Key strategies driving progress include leadership from mayors, national advocacy, and cross-sector collaboration. For instance, in Lusaka, Zambia, the mayor implemented a policy allocating 20% of parking fee revenues to fund safe infrastructure for pedestrians and cyclists.
Regional Significance
Arab cities face similar health challenges, with an increasing percentage of the population living in urban areas. It is crucial for local governments in Arab countries to adopt effective health policies based on successful experiences from global cities. These policies can contribute to improving the quality of life and reducing diseases.
In conclusion, it is clear that a healthy future heavily relies on local efforts, with cities at the heart of these initiatives. There must be a swift and effective response to health challenges through collaboration between local governments and communities.
