How to rooftop gardens became a Singaporean icon

Rooftop gardens have become a Singaporean icon due to a combination of government initiatives, urban planning, environmental goals, and cultural factors.

1. Government Initiatives

The Singaporean government has played a pivotal role in promoting rooftop gardens through various policies and programs aimed at creating a greener and more sustainable urban environment.

Key Programs:

  • Skyrise Greenery Incentive Scheme (SGIS): Launched in 2009, this scheme provides financial incentives for building owners to install rooftops and vertical greenery. The aim is to reduce urban heat, enhance biodiversity, and improve air quality.
  • Green Building Masterplan: This includes the promotion of green building standards and the incorporation of rooftop gardens as part of sustainable building practices.

2. Urban Planning

Singapore’s limited land area and dense population have necessitated innovative urban planning solutions. Rooftop gardens are a critical component of these solutions, helping to optimize the use of vertical spaces.

Urban Planning Strategies:

  • Integration into Public Housing: The Housing and Development Board (HDB) has integrated rooftop gardens into public housing estates, making green spaces accessible to a large segment of the population.
  • Urban Redevelopment Authority (URA) Policies: URA’s guidelines encourage the inclusion of rooftop gardens in new developments to enhance urban aesthetics and provide communal spaces.

3. Environmental Goals

Rooftop gardens contribute to Singapore’s broader environmental and sustainability goals, aligning with the country’s commitment to becoming a “City in a Garden.”

Environmental Benefits:

  • Urban Heat Island Mitigation: Rooftop gardens help cool urban areas by absorbing heat and providing shade, thereby reducing the urban heat island effect.
  • Stormwater Management: They assist in managing stormwater runoff, reducing the burden on urban drainage systems and decreasing the risk of flooding.
  • Biodiversity Enhancement: Rooftop gardens create habitats for various plant and animal species, increasing urban biodiversity.

4. Cultural and Social Factors

Rooftop gardens in Singapore also reflect cultural values related to nature, community, and well-being.

Cultural Influences:

  • Community Spaces: These gardens serve as communal areas where residents can interact, relax, and engage in urban farming, fostering a sense of community.
  • Health and Well-being: Access to green spaces is linked to improved mental and physical health, which resonates with Singapore’s focus on enhancing the quality of life for its citizens.
  • Aesthetic and Recreational Value: Rooftop gardens contribute to the city’s aesthetics and offer recreational opportunities, making urban life more pleasant and attractive.
