What this lesson teaches
I can assess the conditions Singapore needs to keep developing sustainably.
Syllabus K329, Topic 5.3, Key Question 4. How might Singapore continue to develop sustainably?
Make a guess
A policy worked well in Singapore twenty years ago. Will it work just as well today?
- No, not necessarily. Conditions and needs change.
- Yes, because Singapore's needs stay much the same.
- Yes. A policy that worked before will work again.
- No, because old policies are out of date.
Show the answer
No, not necessarily. Conditions and needs change.
Limits, costs and who benefits shift over time. A good proposal is judged on how it works now, who gains and how it can adapt.
Singapore's future depends on healthy ecosystems, people with the skills and will to act, and government that keeps improving its plans.
Singapore depends on global life-support systems: a stable climate, water cycles, biodiversity and resources. Local ecosystems also provide key services. Limited land narrows its choices. Haze and climate change cross borders, so local action and international cooperation must go together.
Economic capability means having the skills and money to act. All stakeholders, including businesses, households and communities, must commit and contribute. Costs and benefits can fall on different groups at different times. Even a good technology may lose support if people cannot afford it or are left out of its benefits.
Political will means keeping up commitment over time. Good governance turns that into investment and cooperation. Leaders need evidence to spot and fix weaknesses. To judge a proposal, ask how it works, whether it is carried out, who benefits and how it can adapt.
- Global life-support
- Stable climate, water cycles, biodiversity, resources.
- Constraints
- Limited land, haze and climate change.
- Governance
- Political will, evidence and regular review.
Step by step
Environmental limits
Land, ecosystems and cross-border threats.
Ability to act
Skills, money and willing stakeholders.
Long-term commitment
Invest, review results and adapt.
Real examples to use
Tengeh floating solar farm (2021)
With little spare land, PUB and Sembcorp put 122,000 solar panels on 45 hectares of Tengeh Reservoir. The 60 megawatt-peak farm offsets about 7% of PUB's yearly energy use.
Electricity imports (EMA)
Natural gas makes about 95% of Singapore's electricity. Singapore aims to import up to 6 gigawatts of low-carbon electricity from the region by 2035, about a third of its supply. This depends on partners, undersea cables and political will on both sides.
Worked example: A coastal choice
A new sea defence may reduce flooding but harm habitats and cost public money. A good judgement compares protection with ecological effects, upkeep and alternatives. It asks who is protected and whether the design can adapt to higher seas.
Watch out for this
A policy that worked before will always work again.
Climate, technology, needs and costs change. Check whether past success still fits.
Check your understanding
Which conclusion shows the best geographical reasoning?
- A measure helps if it cuts risk and stays affordable, fair and adaptable.
- Local success means Singapore can rely less and less on global trade systems.
- The most expensive measure is likely to be the most sustainable.

A measure helps if it cuts risk and stays affordable, fair and adaptable.
Yes. It gives a judgement with conditions.
