Make Streets for People, Not Just Cars
One of the most effective changes is improving walkability. Poorly designed or non-existent footpaths force pedestrians into traffic, increasing accident risks and discouraging physical activity. By contrast, creating continuous, well-maintained sidewalks
encourages walking, which is a powerful and cost-effective public health intervention. A project in Chennai that built over 100 kilometres of footpaths not only reduced CO2 emissions but also helped prevent hundreds of deaths annually from noncommunicable diseases by promoting more active lifestyles. This shift doesn't always require massive budgets. Tactical urbanism—using low-cost, temporary materials like paint and planters to create pop-up bike lanes or widen footpaths—allows cities to test what works before committing to permanent changes. Such initiatives make streets safer and can reduce respiratory diseases and cardiovascular issues by cutting down on vehicular pollution.
Bring Nature into the Neighbourhood
Adding green spaces to densely populated areas has a profound impact on both mental and physical health. Community gardens, for instance, are a powerful tool. Managed by local residents, these gardens can provide fresh produce, create cooling zones to combat the urban heat island effect, and foster a sense of community. Studies have shown that even a modest increase in green cover can prevent a significant number of deaths by reducing pollution, stress, and heat. Greenery along footpaths not only provides shade but also has a calming effect, making walking a more pleasant and less stressful experience. Initiatives like community rooftop gardens in Chennai or the revival of green spaces at Jakkur Lake in Bengaluru show how residents can reclaim and reshape their environment for collective well-being.
Rethink Public Spaces for Connection
Urban life can often lead to isolation and stress, with studies showing that city dwellers face a higher risk of depression and anxiety. Poorly designed public areas, lack of safety, and weak community links are significant contributors. Small changes can transform underused or unsafe areas into vibrant community hubs. Tactical urbanism techniques like adding benches, organising outdoor movie screenings, or creating temporary pedestrian plazas can encourage social interaction and build community trust. When people feel safe and have places to gather, it strengthens social bonds, which is a crucial component of mental health. In cities like Pune and Bengaluru, initiatives promoting cycling and walkability have not only improved mobility but also fostered more community connection.
Improve Access to Local Health Services
Beyond the built environment, small shifts in healthcare delivery can make a big difference. The Government of India's National Urban Health Mission (NUHM) aims to address the needs of the urban poor by establishing Urban Primary Health Centres (UPHCs) and deploying frontline workers like ASHAs. These centres bring essential services closer to communities, making preventive care and early diagnosis more accessible. Ensuring these local clinics are well-staffed and supplied is a critical small step with large-scale benefits. Furthermore, engaging with the private sector through public-private partnerships can help fill gaps and expand the reach of quality healthcare to vulnerable populations living in urban slums. By focusing on community-based, accessible primary care, cities can manage health issues before they become crises.
