What this lesson teaches
I can explain how climate change affects Singapore and the challenges and opportunities it brings.
Syllabus K329, Topic 5.2, Key Question 1. How might climate change affect Singapore?
Make a guess
In 2024 Singapore had 16.5 million visitor arrivals, still below the 19.1 million of 2019. What happened to tourism receipts that year?
- They stayed below 2019, like the arrivals.
- They reached a record S$29.8 billion.
- They fell, as visitors spent less per trip.
Show the answer
They reached a record S$29.8 billion.
Fewer visitors spent more in total than in any earlier year, so spending recovered faster than visitor numbers. Arrivals alone do not show income.
A named place with a date or figure, linked to your point, turns a general answer into a developed one.
This lesson collects the 12 named examples from the lessons in this chapter, so you can revise them in one place. Each one is also a recall card below, so you can save the whole set and review it before an exam.
Singapore's climate risks: Rising temperatures; Flash floods on Orchard Road, 2010; Low-lying land (NCCS).
Climate adaptation in Singapore: Coastal protection; Long Island; Higher land for new building (PUB).
Regional tectonic hazards: Indian Ocean tsunami, 2004.
Preparedness and international cooperation: Operation Lionheart; AHA Centre.
Tourism benefits and costs: Visitors and spending in 2024 (STB); Changi Airport.
Tourism challenges and opportunities: Integrated resorts.
To use a case, name the place or organisation, give its date or a figure, then say what it shows about the question. One developed case earns more than a list of names.
- Rising temperatures
- Singapore's annual mean temperature has risen by about 0.25 degrees Celsius per decade since 1948, faster than the global average, partly because of the urban heat island effect.
- Flash floods on Orchard Road, 2010
- Heavy rain flooded shops and basements at Liat Towers, showing how intense storms can overwhelm drains in a built-up city.
- Low-lying land (NCCS)
- About 30% of Singapore's land is less than 5 m above mean sea level, so rising seas and storm surges threaten a large share of the island.
- Coastal protection
- In 2019, the government said Singapore may need to spend S$100 billion or more over 100 years to protect its coasts from rising seas.
- Long Island
- A 2023 proposal would reclaim land off the East Coast to protect low-lying areas from rising seas and add space for housing and parks.
- Higher land for new building (PUB)
- Since 2011, newly reclaimed land must be at least 4 m above mean sea level, up from 3 m. Critical sites such as Changi Airport Terminal 5 and Tuas Port are being built at least 5 m above it.
- Indian Ocean tsunami, 2004
- An earthquake on the Sunda Megathrust off Sumatra caused a tsunami that killed over 200,000 people around the Indian Ocean. Singapore was shielded by Sumatra and the Malay Peninsula.
- Operation Lionheart
- Singapore's Civil Defence Force sends search-and-rescue teams abroad, for example to Nepal in 2015 and Turkey in 2023.
- AHA Centre
- ASEAN set up the AHA Centre in 2011 to coordinate disaster help among Southeast Asian countries.
- Visitors and spending in 2024 (STB)
- Singapore had 16.5 million visitor arrivals in 2024, 21% more than in 2023 but still below the 19.1 million of 2019. Tourism receipts reached a record S$29.8 billion. So spending recovered faster than visitor numbers.
- Changi Airport
- In 2025 Skytrax named Changi the World's Best Airport for the 13th time. Good air links bring in visitors, but also connect Singapore to shocks such as pandemics.
- Integrated resorts
- Marina Bay Sands and Resorts World Sentosa opened in 2010 and helped visitor arrivals reach 19.1 million in 2019.
Step by step
Name it
The place, event or organisation.
Prove it
A date, number or specific fact.
Link it
Say what it shows about the question.
Worked example: From a name to a developed point
Weak: "There are real examples, such as Rising temperatures." Strong: "Singapore's annual mean temperature has risen by about 0.25 degrees Celsius per decade since 1948, faster than the global average, partly because of the urban heat island effect." The strong version gives the place and the evidence, so it can earn a development mark.
Watch out for this
Naming a famous example is enough to earn the mark.
Examiners credit a developed case: a place, a date or figure, and a clear link to the question.
Check your understanding
Which is the strongest way to use a named example in an answer?
- Give the place, a date or figure, and its link.
- Describe the example in general terms, without a place or figure.
- List several example names, with no details.
Show the answer
Give the place, a date or figure, and its link.
Yes. A located, evidenced and linked case is what earns development marks.
