Environmental Issues

There are a number of environmental issues faced by Malaysia, such as deforestation and pollution. According to a study by Centre for Marine and Coastal Studies in 2008, about 30% of Malaysian coastline is subject to varying degrees of erosion. According to the United Nations, Malaysia's deforestation rate is the highest among tropical nations. The country's annual deforestation rate increased 86% between 1999–2000 and 2000-2005. Malaysia lost an average of 140,200 hectares of its forests or 0.65% of its total forest area every year since 2000, whereas in the 1990s, the country lost an average of 78,500 hectares, or 0.35 percent of its forests annually.

Widespread urbanisation, agricultural fires and forest conversion for oil palm plantations and other forms of agriculture are the main causes of Malaysia's high deforestation rate. Logging is responsible for forest degradation in the country, and local timber companies have been accused by environmental organisations of failing to practice sustainable forest management.

Mining in peninsular Malaysia has left a mark on the environment. Deforestation, pollution of rivers, and siltation have resulted in losses of agriculture, and road projects have opened new areas to colonisation.

Air pollution from industrial and vehicular emissions is a major issue in the urban areas of Malaysia. Malaysia is ranked 42nd in the world in terms of vehicle ownership per capita, with 273 Malaysians having vehicles out of every 1000. Public transportation has been introduced in the form of bus networks and railway systems as mitigation, but utilisation rates are low.

Water pollution occurs due to the discharge of untreated sewage; the west coast of the Peninsular Malaysia is the most heavily populated area. 40% of the rivers in Malaysia are heavily polluted. The country has 580 cubic km of water, of which 76% is used for farming and 13% is used for industrial activity. Cities in Malaysia produce an average of 1.5 million tons of solid waste per year.

In 2000, Malaysia was ranked fourth in the world in terms of per capita greenhouse gas emissions after taking into account land use change with 37.2 tonnes of carbon dioxide equivalent per capita.

Periodic fires, which usually coincide with the events of el Niño, burn thousands of hectares of forests across Malaysia, especially in Malaysian Borneo. The haze originating from these fires and the fires in Kalimantan, Indonesia typically have adverse health effects on the populace, besides causing air pollution. In particular, the 1997 Southeast Asian haze, the 2005 Malaysian haze and the 2006 Southeast Asian haze were caused by slash and burn activities in neighbouring Indonesia.
