  • Urban Liveability in an Industrial Park on a Landfill
    Estelle Chan, Transforming No-Go Zones in Singapore, 47th ISOCARP Congress 2011 Transforming No-Go Zones in Singapore: Urban Liveability in an Industrial Park on a Landfill Creating Land for More People to Work, Live and Play Singapore is a Southeast Asian island city-state located south of the Malay Peninsula. Founded by the British as an entrepot port in the 19th century, the country later gained national independence in 1965. As a sovereign state, the island of Singapore alone houses the multitude of its land uses that contribute to the smooth running of the city-state, from military bases, water catchments to industrial, commercial and residential areas. As such, it was apparent very early on that more land beyond the island would be required to facilitate the nation’s continued growth. Consequently, land mass in Singapore has grown by roughly 25% from 1965 to 2010 through substantial reclamation on offshore islands as well as on the coasts of the main island. Expectedly, the land increase has also been accompanied by a sharp population growth from 1.89 million in 1965i to 5.1 million in 2011, with another projected increase to 6.5 million over the next 40 or 50 years (Figure 1).ii Figure 1: (from left to right) Singapore’s land area and population in 1965, 2010 and 2050 (projected). Singapore’s land area will have increased by about 25% in under a century, and the population is projected to increase by 250% within the same time period. The grey areas represent industrial land use. Sources: JTC Corporation; Department of Statistics, Singapore.

  • Discover the Evolution of Singapore's Award-Winning Residential Town With
    MEDIA RELEASE For immediate release DISCOVER THE EVOLUTION OF SINGAPORE’S AWARD-WINNING RESIDENTIAL TOWN WITH THE NEW TAMPINES HERITAGE TRAIL From swamps and kampongs to a thriving town Singapore, 6 September 2017 – Forget the iconic Tampines Mall or Tampines One. If you were to make your way to Tampines 40 years ago, you would have to do so through a dusty winding road that passes through kampongs and farms. Back then, Tampines Road was the main access to the ulu district that was mostly used by coconut plantation workers, sand miners and travelling hawkers, who catered to far-flung village clusters there. 2 The newly launched Tampines Heritage Trail is the National Heritage Board’s (NHB) 17th heritage trail. Trail-goers can discover and revisit the iconic sites and stories of Tampines – a once rural district that has undergone a transformation into an award-winning1 town. The trail features 18 heritage sites, five of which feature heritage markers, and is part of NHB’s ongoing efforts to document, celebrate and promote the distinct histories and social memories of different areas in which Singaporeans live, work and play. First Green Spaces Thematic Trail 3 In addition to the staple heritage trail offerings of heritage markers, a trail booklet, and a trail map in four languages (English, Mandarin, Malay and Tamil), NHB has created three thematic short routes that span an average of 6km each for trail-goers to explore the unique history and cultural heritage of Tampines. They are: “Tampines Town Trail” (90 minutes; bus and walk) – This route explores some of the town planning innovations of Tampines, and sites of everyday heritage that are part and parcel of life in the neighbourhood.

  • Singapore Raptor Report January 2020
    Singapore Raptor Report January 2020 Himalayan Vulture, near The Pinnacle@Duxton, 9 Jan 2020, by Bp Chua Summary for migrant species: The Himalayan Vultures stole the show in January. Amazingly, a total of 12 immature vultures showed up, besting the previous high of 9 immature birds in January 1992. On the 8th, one vulture was photographed at The Pinnacle@Duxton at 2:24pm, flying east, and another two were photographed at Cashew Road at 2:45pm. At 6:25pm, a flock of ten vultures, initially mistaken for Asian Openbills, were photographed at Bedok, flying towards Siglap. Shortly after 7pm, up to 11 vultures were captured on video flying at the Tanjong Pagar area around Amara Hotel and The Pinnacle@Duxton. One vulture even landed on the roads - Peck Seah Street & Maxwell Road, causing vehicles to slow down and avoid the bird. Members of the public expressed shock in seeing such a huge bird, which eventually flew off to safety. The vultures must have roosted on the tall building in the Tanjong Pagar area as they were spotted on top of the buildings on the morning of the 9th. Twelve vultures were spotted and after 9am, they took flight, heading south towards Sentosa, but then turned back, probably dreading to fly over the open sea. By around 11am, eleven vultures were spotted flying over Fort Canning Park and by noon time, twelve vultures were spotted at Dairy Farm Nature Park – they were heading north. Page 1 of 13 There were no sightings of the vultures on the 10th. Then on the 11th, nine vultures were spotted at West Coast Park in the afternoon, flying west.
