Singapore’s natural resources are characterized by severe land and mineral scarcity, prompting world-class resource stewardship through water reclamation, solar deployment, and strategic maritime location. The city-state lacks domestic fossil fuels and maintains just 0.6 km³ of internal freshwater, but leverages 2,497 mm of annual rainfall, 17 water reservoirs, high-tech NEWater recycling meeting 40% of demand, and protected green corridors like Bukit Timah Nature Reserve.
Singapore is an island nation situated in Southeast Asia at the southern tip of the Malay Peninsula, highlighted within our regional overview of Asia natural resources and the global natural resources by country directory. Despite its compact land area of approximately 744 km², the city-state is a preeminent global financial, logistics, and trading hub.

However, owing to its geography and dense urban footprint, domestic availability of conventional natural resources—such as fossil fuels, metallic ores, and vast arable land—is exceptionally constrained.
As a result, Singapore has had to rely on international trade and circular innovation to meet domestic needs, pioneering closed-loop water reclamation, advanced desalination, and regional clean energy imports to ensure long-term resource resilience.
What natural resources does Singapore possess? What natural wealth characterizes the city-state? How does it secure its water and energy supply, and how does it safeguard its rich urban wildlife?
Natural Resources
Natural resources are materials or energy sources provided or found on Earth that are useful to humans; explore our foundational guide to the main types of natural resources for broader context. Every physical good in modern society stems from natural resources.
- Renewable resources: can replenish naturally through cyclical ecological processes faster than they are consumed. Examples include solar radiation, rainfall catchments, recycled water flows, and native flora and fauna.
- Non-renewable resources: finite geological stocks that once consumed cannot regenerate on human timescales. Examples include petroleum, natural gas, coal, and minerals.

Water Resources of Singapore
Singapore possesses a renewable freshwater volume of approximately 0.6 km³, ranking 145th globally. Lacking natural lakes and sizable aquifers, water security has been an existential driver of national innovation. Read our comprehensive report on global water resources.
Among its principal urban waterways are the Kallang and Singapore rivers, alongside 17 engineered freshwater reservoirs, with the Marina Barrage creating an iconic urban reservoir that supplies drinking water and mitigates city flooding.
Average Rainfall and Soils of Singapore
Singapore experiences an abundant equatorial rainfall averaging 2,497 mm per year, placing it 13th globally in precipitation depth. Rain falls consistently throughout the year, especially during the northeast monsoon. Soils are largely intensely weathered tropical oxisols and laterites, supplemented by extensively engineered urban landfill and coastal reclamation sands.
Forest Resources of Singapore
According to World Bank data, forest and tree canopy covers approximately 20.9% of Singapore’s territory, spanning roughly 150 km². Explore our dedicated analysis of global forest resources.
Environmental Performance and Protection of Singapore’s Natural Resources
Singapore achieved an Environmental Performance Index score of 53.0 in the 2024 EPI, ranking 47th globally according to the Yale Center for Environmental Law & Policy 2024 results. Under its “City in Nature” vision, the government actively connects remaining primary rainforest patches at Bukit Timah with secondary forests and urban nature corridors.

Biodiversity: Animal and Plant Resources of Singapore
Birds of Singapore
Singapore records an impressive avian community of more than 400 bird species, serving as a critical stopover on the East Asian-Australasian Flyway.
Prominent species include the Oriental pied hornbill (re-established through active nest-box programs) and migratory shorebirds at Sungei Buloh Wetland Reserve.
Fish and Amphibians of Singapore
A total of 30 amphibian species are recorded in Singapore, inhabiting freshwater swamp forests and nature reserves.
In addition, Singapore counts 719 fish species across freshwater and coastal marine waters, notably including catfishes and native barbs. However, 29 of these fish species are currently classified as threatened.
Mammals of Singapore
Singapore harbors 87 mammal species, ranking 89th in the world. Native species include the Sunda pangolin (Manis javanica), the Raffles’ banded langur, and the Malayan colugo living within protected forest reserves.
Reptiles of Singapore
Singapore sustains a diverse herpetofauna of 149 reptile species, ranking 63rd worldwide. Prominent reptiles include the Asian water monitor lizard (Varanus salvator), reticulated pythons, and estuarine crocodiles.
Organizations That Protect or Study Singapore’s Natural Resources
- National Parks Board (NParks) – Lead statutory agency responsible for green spaces, biodiversity conservation, and urban wildlife management.
- ACRES – Promotes animal welfare, rescues native wildlife, and tackles illegal wildlife trafficking.
- WWF Singapore – Focuses on marine conservation, sustainable finance, and reducing deforestation in regional supply chains.
- National Environment Agency (NEA) – Ensures environmental cleanliness, waste management, and air quality control.
Singapore represents an extreme case of a nation with virtually no domestic extractive resources: it imports more than 90% of its food from roughly 170 countries and regions, according to the Singapore Food Agency (SFA). Scarcity—of land, water, energy, and food—defines its resource strategy and has compelled the country to engineer what nature withheld.
Energy: Almost Entirely Imported
Singapore possesses no indigenous oil or gas deposits. Approximately 95% of its electricity is generated from imported natural gas, according to the Energy Market Authority (EMA, 2025); the remainder is supplied by diesel, municipal waste-to-energy incineration, coal, and rooftop/floating solar. To diversify, Singapore established a target to import 6 GW of low-carbon electricity from regional neighbors by 2035, covering roughly 30% of its projected electricity demand (EDB / EMA, 2024). See our global guide on energy resources.
Land Reclaimed from the Sea
Confronting severe territorial limits, Singapore expanded its geography through extensive maritime land reclamation. Its land area expanded by about 28% since independence in 1965, from 581.5 km² to approximately 744 km² in 2025 (GeoJournal and urban planning studies). Future plans anticipate an additional 7% to 8% expansion by 2030 to accommodate deepwater port infrastructure, industry, and residential housing.
Recycled Water: NEWater
With limited river systems and natural aquifers, Singapore turned treated wastewater into an ultra-pure resource. Recycled water—NEWater, processed through microfiltration, reverse osmosis, and ultraviolet disinfection—meets approximately 40% of the nation’s daily water demand (PUB via WaterWorld). Utilized primarily for wafer fabrication plants and reservoir storage buffering, it serves as one of Singapore’s famed “Four National Taps”.
Frequently Asked Questions
Does Singapore possess indigenous energy resources? Virtually none: around 95% of its electricity is generated using imported natural gas. The country aims to import 6 GW of low-carbon electricity by 2035 to cover 30% of national consumption (EMA, 2025).
Where does Singapore get its water without sizable natural freshwater bodies? Through its “Four National Taps” framework: local catchment runoff, imported water from Johor (Malaysia), desalinated seawater, and ultra-purified recycled water (NEWater), with NEWater supplying approximately 40% of daily demand (PUB via WaterWorld).
