Singapore has placed a strong emphasis on ecological development since it gained independence in 1965, evolving from a "garden city" to a "city in a garden". Today, over 50% of its land is covered by green spaces. One remarkable example is Gardens by the Bay, a 101-hectares of urban natural park created through land reclamation. Central to Singapore's transformation is the strategic use of spatial data.
Benefits to biodiversity
Satellite imagery can play a pivotal role in monitoring and managing a city-state's green spaces. By providing a comprehensive view of urban landscape, authorities can assess vegetation coverage, monitor changes over time and ensure the overall health of the ecosystem. This data-driven approach helps maintain a balance between the built environment and the natural world.
Furthermore, satellite imagery can support city planners, conservationists and environmental agencies with decision-making about sustainable land use, effective green space management and future development projects. With real-time data at their fingertips, authorities can proactively address ecological challenges, safeguard biodiversity hotspots and create an urban environment in harmony with nature.
History of Gardens by the Bay
One remarkable testament to Singapore's commitment to ecological development is Gardens by the Bay. Spanning 101 hectares, this urban natural park is a masterpiece of landscape architecture and conservation. Comprising three riverside gardens, namely Bay East Garden, Bay Central Garden and Bay South Garden, this green oasis is a sanctuary for nearly 500,000 different species of plants, attracting millions of visitors from around the globe each year.
Bay South Garden, the largest of the three gardens, serves as a showcase for tropical horticulture and garden art. Launched in 2012, this 54-hectare park boasts a collection of 250,000 species of rare and endangered plants, carefully curated to represent the rich diversity of tropical flora. Among its highlights are the iconic super-trees, towering metal structures adorned with lush vertical gardens. These towering giants provide habitat for various species of birds and insects, demonstrating how architectural design and ecological conservation can coexist.
More than just a tourist attraction, Gardens by the Bay is a living testament to Singapore's commitment to sustainability. The supertrees are equipped with photovoltaic cells, harnessing solar energy to illuminate the park at night. Additionally, the park's rainwater harvesting system collects and recycles rainwater, ensuring the efficient use of water resources.
Through the fusion of ecological vision and technological advancements, Singapore continues to flourish as a "city in a garden," inspiring other urban centres worldwide to pursue a greener, more sustainable future.
