Striking a perfect balance

While the vitality of trees and shrubs in any locality is undisputed, their existence in urban settings, particularly along the road, should be managed meticulously to balance aesthetics, safety, and sustainability

A recent news article highlighted the growing concern about the unchecked growth of trees and shrubs along roadsides and dividers in Delhi. This issue has caused accidents and posed threats to motorists and pedestrians alike. While trees and greenery play a vital role in urban landscapes, offering shade, colour, and environmental benefits, it is essential to strike a balance between nature and urban infrastructure to ensure safety and sustainability.

In urban settings, trees and shrubs are planted for various reasons: to enhance the aesthetics of public spaces, offer fragrance and fruit, and provide shade. Beyond their visual appeal, they play a critical role in improving air quality, reducing pollution, and supporting biodiversity. Green spaces also help mitigate rainwater runoff, soil erosion, and flooding while positively impacting mental wellbeing by reducing stress levels. However, urban greenery should not aim to replicate dense forests or jungles. Instead, it should be thoughtfully managed to integrate with the city’s architecture and infrastructure.

The challenges of roadside vegetation management

Trees in urban environments face different challenges than those in natural forests. They contend with pollution, limited space, compacted soil, and fluctuating weather conditions. As a result, these trees often require consistent maintenance, including pruning, disease control, and irrigation. When neglected, overgrown trees and shrubs can obstruct traffic signals, streetlights, and road signs, creating hazards for drivers, cyclists, and pedestrians. Misshapen or oversized trees also pose risks during extreme weather events, such as storms or heavy rainfall, potentially damaging buildings, vehicles, and public infrastructure.
