Geography of Singapore - Political and Human Geography

Political and Human Geography

When Singapore was first colonized by the British, the city of Singapore was situated on the southern coast, around the mouth of the Singapore River. This area remains the Downtown Core of Singapore. The rest of the island was farmland and primary rainforest. However, since the 1960s the government has constructed many new towns in other areas, so that today the island is nearly entirely built-up and urbanised, with only a few exceptions, such as Bukit Timah Nature Reserve or reclaimed land in the process of being developed. However, even though Singapore is nearly totally urban, the Central Area, which contains a high concentration of financial and commercial districts because this area is closest to Singapore's port.

The Urban Redevelopment Authority is the government agency responsible for the urban planning of Singapore, which seeks to implement efficient land use, minimise pollution while maintaining convenient transport, which are Singapore's largest concerns because of its situation as a city-state. A Development Guide Plan has been released in the process. In order to reduce traffic congestion, Electronic road pricing (ERP) has been enacted around entrances into the Central Area. The other parts of Singapore are less dense and busy, and are often filled with housing estates such as from the Housing and Development Board (HDB) or condominiums, and commercial districts are less concentrated. However, to reduce strain on the Central Area, several regional centres have been developed, each containing a concentrated commercial district.

Light industry tends to be distributed around the island as industrial estates and located in flats, similar to the HDB, and only allow tenants which produce close to nil pollution, whereas heavy industry tends to be located around Jurong and Jurong Island. A list of such estates can be found here.

There are two connections to the state of Johor, Malaysia. In the north there is a causeway for both rail and road traffic, which connects to the city of Johor Bahru. In the west there is a road bridge (Tuas Second Link), which connects to Johor, for road traffic only. The connections are an important economic link to Malaysia, which can be seen as a hinterland.

The causeway (1,038 m in length) was designed by Coode, Fizmaurice, Wilson and Mitchell of Westminster and constructed by Topham, Jones & Railton Ltd of London. It was started in 1909 as a railway link by Johor State Railway to connect Johor Bahru to Singapore, then the administrative headquarters of British interests in Southeast Asia. Construction of the road section started in 1919 and completed in 1923.

The causeway has caused ecological problems, most notably accumulation of silt in the Johore Strait. This has led to disagreements with Malaysia. Singapore has rejected Malaysia's proposal to replace the causeway with a bridge, and Malaysia has since proposed the idea of what became known as "the crooked half-bridge", descending halfway to link up with the low-level causeway.

Since Singapore lacks natural freshwater rivers and lakes, the primary source of domestic water is rainfall. Demand for fresh water is approximately twice that supplied by rainfall, so Singapore imports much of its fresh water from Malaysia and Indonesia. To lessen its reliance on imports, Singapore has built reservoirs to collect rainwater and recycled water facilities. In addition, Singapore has built a desalination plant on the western coast of Tuas. This plant is expected to at least meet half of Singapore's water demands. Recent plans to produce NEWater-recycled water from treatment by filtration via reverse osmosis have been very successful as the government has opened up three plants around the island to help meet the demand.

There are more than 300 parks and 4 nature reserves in Singapore. There are also many trees planted, and almost fifty per cent of the country is covered by greenery. Because of this, Singapore is also commonly known as the 'Garden City'.
