The Malacca Straits

The Malacca Straits have long been an important trade route linking the Ind ian Ocean to the South China Sea and Pacific Ocean. From the seventh to the eleventh century, the Srivijaya empire controlled them, followed in the fi fteenth century by the port kingdom of Malacca. Western maritime powers als o recognized the strategic importance of the Straits, and in 1511, the Port uguese captured Malacca. In 1641, the Dutch occupied what is now known as J akarta, and from the seventeenth to the eighteenth century, the Dutch East India company controlled the trade in the Straits (Ross et al,, 1995). The British also recognized the need to control the Straits to ensure the safe passage of British merchant ships on their way to China, and in 1819 establ ished a colony in Singapore. In 1824, the British and the Dutch ended their rivalry with a treaty whereby Britain agreed to 'safeguard the Straits and keep them open for other friendly nations' (Chia, 1998). In recent years, the Straits have become a very important trade route. In 1 993 and 1995, over 100 000 oil and cargo vessels traversed it each year, ca rrying 3.23 million barrels of crude oil through the Straits each day (Saku ra Institute of Research, 1998), Shipping accidents have occurred more freq uently, recently, which is attributed to heavy traffic in the Straits with shallow, narrow channels and shoals, Despite these hazards, economic effici ency dictates that vessels continue to use the Straits. The Straits are also rich in renewable and non-renewable resources, includi ng productive coastal ecosystems, extensive capture fisheries, aquaculture, coastal tourism, mining and valuable natural gas reserves. This chapter looks at the natural environmental conditions and the status o f the coastal resources, the sustainability of existing activities, critica l environmental problems and management. It is based on the Malacca Straits Environmental Profile (Chua et al., 1997) and other studies undertaken by the GEF/UNDP/IMO Regional Programme for Marine Pollution Prevention and Man agement in the East Asian Seas, referred to as the Regional Programme in th is document.
