Environmental issues in Singapore
Environmental issues in Singapore include air pollution, water pollution, and deforestation. The government established the Singapore Green Plan in 1992 to help with environmental issues.
Deforestation
Since the founding of Singapore in 1819, more than 95% of its estimated 540 square km of vegetation has been cleared. At first for short-term cash crops and later because of urbanization and industrialization. 61 of its original 91 bird species has been lost leading to many native forest plants not being able to reproduce because of loss of seed dispersal and pollination.Since 1980, development and increased pressure for land usage has led to Singapore losing 90% of its forests, 67% of its birds, 40% of its mammals and 5% of its amphibians and reptiles. In 2011, vegetation covered 56% of Singapore's total land area, including 29% spontaneous and 27% artificially managed forest.
Singapore had a 2018 Forest Landscape Integrity Index mean score of 1.11/10, ranking it 165th globally out of 172 countries.
Land reclamation

As a result of the nation’s ambitious land reclamation, environmental impacts extend beyond its shores too. Singapore’s shores have expanded by 22% since its independence and Singapore has become one of the largest importers of sand in the world, importing 517 million tonnes in the last 20 years alone. Most of this sand was sourced from Indonesia and Malaysia until both countries imposed a ban due to the environmental impact—Indonesia saw 24 islands disappear. Sand dredging in Cambodia has also threatened its coastal environments, endangered species and the livelihoods of fishing villages.
Air pollution
In 1984, there were health concerns with the great number of pig farms in Singapore. They were deemed to have contributed to the pollution of the country, namely to the air. This problem was solved by reducing the number of such farms. of carbon dioxide were emitted in the country in 1996, ranking among the highest emission levels in the world. Air polluters in Singapore are mostly, but not only, vehicles for transport, despite the country's tough regulations. The country had been blanketed in haze for a period of time, which was contributed by smoke from Indonesian fires.Water pollution
Singapore is a country with limited water resources, and it is essential for its water quality to be carefully regulated.Water in Singapore is polluted by unwanted materials contributed by industrial facilities, coupled by oil from both incoming and outgoing trading vessels. Corrective measures are taken, and affected water is taken for treatment at specialised centres. Plants such as NEWater treat unwanted water into drinkable water. One major water body in Singapore which used to be polluted is the Singapore River.
