SINGAPORE STRAIT

channel extending for 65 miles (105 km) between the Strait of Malacca (west) and the South China Sea (east). The strait is 10 miles (16 km) wide and lies between Singapore Island (north) and the Riau Islands (south), part of Indonesia. It includes Johore Strait (q.v.), Keppel Harbour, and many small islands. As the deepwater approach to the port of Singapore, the strait is one of the world's busiest commercial routes. The economy Singapore, one of the great trading entrepts of the British empire, has experienced remarkable economic growth and diversification since 1960. In addition to enhancing its position as a world trade centre, it has developed powerful financial and industrial sectors. Singapore has the most advanced economy in Southeast Asia and is often mentioned along with other rapidly industrializing countries in Asia, notably South Korea and Taiwan. Singapore's economy always has differed from those of the other Southeast Asian countries in that it never has been primarily dependent on the production and export of commodities. Economic development has been closely supervised by the Singaporean government, and it has been highly dependent on investment capital from foreign multinational corporations. The government holds about three-fourths of all land and is the chief supplier of surplus capital, which is derived largely from contributions to the Central Provident Fund (CPF) social-security savings program. In addition, the government has attempted to enhance the value and productivity of labour in order to attract investment and boost export competitiveness. This has been accompanied by a strong commitment to education and health. Labour shortages and rising wages have heightened the push for restructuring the economy even more toward higher value-added production. The rationale for extensive government intervention in economic development has weakened. Official policy relies on market forces, privatization of government enterprise, and more support for domestic private businesses. Union membership has declined as centralized union structures have been replaced by smaller industry- and enterprise-based unions. Greater reliance has been placed on local labour-management negotiations. Resources, agriculture, and fisheries Singapore has few natural resources. There are no natural forests remaining on the island. Only a tiny fraction of the land area is classified as agricultural, and production contributes a negligible amount to the overall economy. Cultivation is intensive, with vegetables and fruits grown and poultry raised for local consumption. The local fishing industry supplies only a portion of the total fresh fish requirement; most of the catch comes from offshore fishing vessels. There also is a small aquaculture industry that raises groupers, sea bass, and prawns. Singapore is a major exporter of both orchids and aquarium fish. The land Relief Nearly two-thirds of the main island is less than 50 feet (15 metres) above sea level. Timah Hill, the highest summit, has an elevation of only 531 feet (162 metres); with other peaks, such as Panjang and Mandai hills, it forms a block of rugged terrain in the centre of the island. To the west and south are lower scarps with marked northwest-southeast trends, such as Mount Faber. The eastern part of the island is a low plateau cut by erosion into an intricate pattern of hills and valleys. These physical units reflect their geologic foundations: the central hills are formed from granite rocks, the scarp lands from highly folded and faulted sedimentary rocks, and the eastern plateau from uncompacted sands and gravels. Drainage and soils A dense network of short streams drains the island, but floods are locally severe because the streams have low gradients and because of excessive water runoff from cleared land. Many streams, especially those draining northward, have broad mangrove-fringed estuaries that extend far inland. None of the soils is even reasonably fertile, but those derived from the granites tend to be better than most. Soils developed from the sedimentary rocks are variable, but many contain hardpans (compacted layers) that restrict plant roots and impede soil drainage. The soils of eastern Singapore are extremely infertile. All have suffered extensive degradation through erosion as a result of generations of careless human exploitation. The people Ethnolinguistic composition The population of Singapore is diverse, the result of considerable past immigration. Chinese predominate, making up more than three-fourths of the total. Malays are the next largest ethnic group, and Indians the third. None of these three major communities is homogeneous. Among the Chinese, more than two-fifths originate from Fukien province and speak the Amoy dialect, about one-fourth are Teochew from the city of Swatow in Kwangtung province, and a smaller number are from other parts of Kwangtung. The Chinese community as a whole, therefore, speaks mutually incomprehensible dialects. Linguistic differences are less pronounced among the Malays, but the group includes Indonesians speaking Javanese, Boyanese, and other dialects. The Indian group is most diverse, consisting of Tamils (more than half), Malayalis, and Sikhs; it also includes Pakistani and Sinhalese communities. Because of this ethnic diversity, no fewer than four official languages are recognizedEnglish, Mandarin Chinese, Malay, and Tamil. English remains the main medium for administration, commerce, and industry, and it is the primary language of instruction in schools. Mandarin, the official language of China, transcends dialect barriers, and its use is strongly promoted; one-third of the school population is taught in that language. Malay, like English, is widely used for communication among ethnic groups and plays a particularly useful role in view of the close ties between Singapore and Malaysia. Religions Religious affiliations reflect ethnic patterns. About two-thirds of all Chinese profess some degree of attachment to Confucianism, Buddhism, or Taoism or to some combination thereof. Virtually all Malays, and some Indians, adhere to Islam, which is the formal religion of about one-sixth of the population. The Christian community has grown rapidly and now constitutes more than 10 percent of the population; nearly all Christians are Chinese. Almost all of the remaining population is Hindu.
