Urban Greening Initiatives: Building Climate-Resilient Indian Cities

Introduction

Urbanization in India has been both a symbol of progress and a challenge for sustainable development. As cities expand, they often encroach upon natural landscapes, leading to reduced green cover and increased environmental vulnerabilities. Urban greening initiatives, encompassing green spaces, rooftop gardens, and urban forests, have emerged as pivotal strategies to counteract these challenges, fostering climate resilience and enhancing the quality of urban life.​epjdatascience.springeropen.com

The Imperative of Urban Greening

Urban areas, characterized by dense infrastructure and limited vegetation, are susceptible to the urban heat island effect, where temperatures are significantly higher than in surrounding rural areas. This phenomenon exacerbates energy consumption, air pollution, and health risks. Integrating green infrastructure into city planning offers multifaceted benefits:​

• Climate Mitigation and Adaptation: Trees and vegetation sequester carbon dioxide, a leading greenhouse gas, thereby mitigating climate change. They also provide shade and release moisture through transpiration, cooling urban environments and reducing reliance on air conditioning.​
• Stormwater Management: Green spaces absorb rainfall, reducing surface runoff and mitigating urban flooding. This natural infiltration replenishes groundwater and alleviates the burden on stormwater infrastructure.​
• Biodiversity Conservation: Urban forests and parks serve as habitats for various species, preserving biodiversity within city landscapes. They act as ecological corridors, facilitating species movement and genetic exchange.​ucem.ac.uk
• Health and Well-being: Access to green spaces promotes physical activity, reduces stress, and enhances mental health. They offer recreational opportunities and improve the overall liveability of urban areas.​

In Mumbai, where space is a premium, the Hiranandani Group pioneered the concept of rooftop gardens. The Delphi terrace garden, spanning nearly an acre, is a notable example. This green rooftop not only enhances the building’s aesthetic appeal but also contributes to temperature regulation, energy savings, and urban biodiversity. Such initiatives demonstrate the potential of vertical greening in densely populated urban areas.​

Case Study: Dilli Haat, Delhi

Dilli Haat, a popular cultural and craft bazaar in Delhi, incorporates rooftop gardens that add greenery to the urban landscape. These gardens provide shade, reduce heat absorption, and create a pleasant environment for visitors, showcasing how green infrastructure can be integrated into commercial spaces.​

Urban Greening Initiatives in Developed Countries: Lessons for India

Developed countries have implemented various urban greening strategies that offer valuable insights for India:​

1. Green Roofs in Basel, Switzerland

Basel has pioneered the use of green roofs, transforming unused space on buildings into verdant habitats that enhance urban biodiversity. The initiative began in the early 1990s when residents agreed to fund energy-saving measures, leading to a mandate that all new and renovated buildings with a slope less than 10 degrees must have green roofs.Basel stands out for its commitment to native seeds and plants, creating biodiverse environments similar to dry grasslands. Green roofs provide multiple benefits, including cooling the air, storing water, reducing air pollution, and providing wildlife habitats. The approach has been supported by research and guidelines from experts like Stephan Brenneisen. Despite challenges like the competition for roof space from solar panels and the need for updates to building codes, the success of Basel’s green roofs demonstrates their potential as a viable, multi-benefit urban solution. ​theguardian.com

2. Urban Green Spaces in European Cities

European cities have emphasized developing and enhancing urban green spaces to halt biodiversity loss, reduce air pollution, and combat heat waves. Projects focus on constructing green mobility corridors, preventing droughts and flooding, and designing buildings with nature-based solutions. These initiatives contribute to achieving climate objectives and improving citizens’ health and well-being. ​urban-initiative.eu

3. Nature-First Urban Planning in Singapore

Singapore has integrated nature into its urban infrastructure, with nearly half of the city now comprising green spaces. This approach not only enhances biodiversity but also improves the quality of life for residents, reduces the urban heat island effect, and enhances resilience to climate change. Singapore’s greening efforts include rooftop gardens, vertical forests on high-rise buildings, and large-scale urban parks like Gardens by the Bay. These initiatives highlight the importance of integrating urban planning with ecological considerations, demonstrating that even densely populated cities can prioritize sustainability without compromising economic development.
