on Pulau Ubin. Pulau Ubin first appeared on map in an 1828 sketch of the Island of Singapore as
Pulo Obin and in Franklin and
Jackson's map as
Po. Ubin. Since the
British founding of Singapore, the island has been known for its granite. The numerous granite quarries on the island supply the local
construction industry. The granite
outcrops are particularly spectacular from the sea because their grooves and fluted sides create
furrows and
ridges on each granite rock slab. These features are captured in
John Turnbull Thomson's 1850 painting —
Grooved stones on Pulo Ubin near Singapore. The granite from Pulau Ubin was used in the construction of
Horsburgh Lighthouse.
Tongkangs ferried the huge rock blocks (30 by 20 feet) from the island to
Pedra Branca, the site of the lighthouse, in 1850 and 1851. Later, the granite was also used to build the
Singapore-Johor Causeway. Most of the quarries are not in operation today and are being slowly recolonised by
vegetation or filled with water. Apart from quarrying,
farming and
fishing were the principal occupations of the inhabitants of the island in the past. It is also called
Selat Tebrau (
tebrau is a kind of large
fish). In the 1970s as the granite quarries closed down and jobs dwindled, residents began leaving. Outlined in
Urban Redevelopment Authority (URA)'s 1993 master plan, there were plans to build an
MRT line connecting the island and
Pulau Tekong to
mainland Singapore as well as HDB apartments on the island by 2030. In 2013, these plans were removed from URA's updated master plans and authorities announced that there were no plans to develop the island. In the 1990s, the government approved land reclamation plans for
Chek Jawa, a
cape and 100-hectare
wetlands located on the south-eastern tip of Pulau Ubin, and when the plans were made public in 2001, it drew public criticism, with Singaporeans making appeals to the government to preserve the biodiversity of Chek Jawa instead. After a biodiversity survey conducted by conservationist volunteers in December, 2001, it resulted in the plans being postponed by the government, with the
Ministry of National Development stating that the island would not be developed if there is no need for it to be. In the URA 2011 concept plan, Pulau Ubin is poised to be developed when Singapore's population exceeds a
threshold of 6.9 million. Pulau Ubin's wooden house villages and wooden jetties, relaxed inhabitants, rich and preserved wildlife, abandoned quarries and plantations, and untouched nature make it the last witness of the old kampung Singapore that existed before modern
industrial times and large-scale urban development. == Human settlement ==
