Section B: Water Resources and Sustainability (Questions 6–10)

Question 6 [4 marks]

(a) [1 mark] Evaporation

(b) [1 mark] Precipitation (accept: rainfall)

(c) [2 marks] The water cycle is important because it continuously replenishes Singapore's water supply through rainfall, which is collected in reservoirs and catchments. Without the water cycle, Singapore would have no natural source of freshwater, as the country has limited land for large natural lakes or rivers.

Marking Notes:

1 mark for linking the water cycle to rainfall/precipitation.
1 mark for explaining the consequence for Singapore's water supply (e.g., replenishing reservoirs, providing freshwater).

Question 7 [4 marks]

(a) [2 marks] Any two of the following:

Local catchment water
Imported water (from Malaysia)
NEWater (recycled/reclaimed water)
Desalinated water

Marking Notes: 1 mark each.

(b) [2 marks] Singapore needs multiple water sources to reduce its dependence on any single source (especially imported water), ensuring water security and resilience against supply disruptions such as droughts or political issues with neighbouring countries.

Marking Notes:

1 mark for identifying the risk of over-reliance on one source.
1 mark for explaining the benefit of diversification (security, resilience, self-sufficiency).

Question 8 [4 marks]

(a) [2 marks]

Working: Total in 2022 = 445 MGD Total in 2019 = 420 MGD Increase = 445 − 420 = 25 MGD

Marking Notes:

1 mark for correct working (subtraction shown).
1 mark for correct answer with unit (25 MGD).
If answer is correct but no working shown, award 1 mark only.

(b) [1 mark] Domestic water use increased steadily from 200 MGD in 2019 to 220 MGD in 2022.

Marking Notes: Accept any description that identifies an increasing/rising trend.

COVID-19 pandemic / circuit breaker measures in 2020 led to reduced commercial/industrial activity.
Factories and businesses reduced operations or closed temporarily.

Marking Notes: Accept any plausible reason linked to reduced economic/industrial activity in 2020.

Question 9 [4 marks]

Answer (any two, 2 marks each):

(a) Take shorter showers to reduce water usage. This directly reduces the amount of water consumed daily, lowering demand on reservoirs and treatment plants.

(b) Use a basin to wash vegetables or dishes instead of running water continuously. This prevents wastage and ensures water is used more efficiently.

Other acceptable answers:

Turn off taps when not in use (e.g., while brushing teeth).
Use washing machines only with full loads.
Reuse water (e.g., use rice water to water plants).
Report leaking pipes to PUB promptly.
Install water-saving devices (e.g., thimble kits, dual-flush systems).

Marking Notes:

1 mark for identifying a valid method.
1 mark for explaining how/why it conserves water.
Award a maximum of 2 marks per method.

Question 10 [2 marks]

Advantage (1 mark): Desalination provides a reliable and weather-independent source of freshwater, as it uses seawater which is abundant around Singapore.

Disadvantage (1 mark): Desalination is energy-intensive and expensive, requiring large amounts of electricity to remove salt from seawater, which increases costs and carbon emissions.

Marking Notes:

1 mark for a valid advantage (e.g., reliable supply, not dependent on rainfall, uses abundant seawater).
1 mark for a valid disadvantage (e.g., high energy use, costly, environmental impact).

Section C: Energy Resources and Sustainability (Questions 11–15)

Question 11 [3 marks]

(a) [2 marks] Fossil fuels are non-renewable because they take millions of years to form from the remains of dead plants and animals under heat and pressure. Once used up, they cannot be replaced within a human lifetime.

Marking Notes:

1 mark for explaining the long formation process (millions of years).
1 mark for stating that they cannot be replenished/replaced in a human lifetime.

(b) [1 mark] Accept any one:

Air pollution / smog
Global warming / climate change (due to greenhouse gas emissions)
Acid rain

Marking Notes: 1 mark for any valid environmental problem.

Question 12 [3 marks]

(a) [1 mark] Natural gas

(b) [1 mark] Possible reasons:

Natural gas is relatively cleaner than coal or oil (produces fewer emissions).
Singapore has established infrastructure (pipelines) to import natural gas from neighbouring countries.
Natural gas is efficient and reliable for electricity generation.

Marking Notes: Accept any plausible reason.

Solar energy is renewable and does not produce greenhouse gas emissions during operation.
It helps Singapore reduce its carbon footprint and meet climate targets.
Singapore has limited fossil fuel reserves, so solar reduces dependence on imports.

Marking Notes: Accept any valid reason linked to sustainability, environment, or energy security.

Question 13 [4 marks]

Answer (any two, 2 marks each):

(a) Singapore has limited land area, which restricts the space available for large-scale solar panel installations. Rooftops and floating solar farms on reservoirs help, but the total capacity is still constrained by land scarcity.

(b) Singapore's tropical climate includes frequent cloud cover and rain, which reduces the amount of sunlight reaching solar panels and makes solar energy generation less consistent and efficient compared to sunnier regions.

Other acceptable answers:

High cost of installing and maintaining solar panels.
Solar energy is intermittent (not available at night), requiring energy storage solutions.
Competition for land use (housing, industry, green spaces).

Marking Notes:

1 mark for identifying a valid challenge.
1 mark for explaining why it is a challenge for Singapore specifically.

Question 14 [4 marks]

(a) [2 marks]

Working: 350 + 320 + 380 + 410 + 450 + 470 = 2,380 kWh

Marking Notes:

1 mark for correct addition/working shown.
1 mark for correct answer with unit (2,380 kWh).

(b) [1 mark] Electricity consumption increased steadily from 350 kWh in January to 470 kWh in June.

Marking Notes: Accept any description that identifies an increasing/rising trend over the period.

Hotter weather in April–June (mid-year) leads to increased use of air-conditioning and fans.
More time spent at home during certain months (e.g., school holidays) increases household electricity use.

Marking Notes: Accept any plausible reason linked to seasonal or behavioural factors.

Question 15 [2 marks]

Answer (any one, with explanation):

The government provides subsidies or rebates for households that switch to energy-efficient appliances (e.g., those with higher NEA energy efficiency labels). This encourages consumers to purchase appliances that use less electricity, reducing overall household energy consumption.

Other acceptable answers:

Public awareness campaigns (e.g., "Climate Action Week") educate households on saving energy.
Mandatory energy labelling helps consumers make informed choices.
Carbon tax incentivises reduced energy use.

Marking Notes:

1 mark for identifying a valid government measure.
1 mark for explaining how it encourages reduced energy consumption.

Section D: Sustainable Resource Management (Questions 16–20)

Question 16 [3 marks]

(a) [1 mark] Singapore is a small island with limited natural resources / limited land, so it cannot produce enough food, energy, or raw materials on its own.

Marking Notes: Accept any answer that references Singapore's small size or lack of natural resources.

(b) [2 marks] A circular economy is an economic system where resources are kept in use for as long as possible through reducing waste, reusing products, and recycling materials, rather than disposing of them after single use. The goal is to minimise waste and make the most of available resources.

Marking Notes:

1 mark for the general concept (reusing/recycling/reducing waste).
1 mark for explaining the purpose (minimising waste, extending resource use).

Question 17 [3 marks]

(a) [1 mark] Accept any one:

Recycling programmes (e.g., blue recycling bins in HDB estates).
Incineration of waste to reduce volume before landfill.
Promoting the 3Rs (Reduce, Reuse, Recycle).
Waste-to-energy plants.

Marking Notes: 1 mark for any valid waste management method.

(b) [2 marks] Reducing waste sent to landfills is important because Singapore's only landfill (Semakau Landfill) has limited capacity and space. If waste continues to grow at the current rate, the landfill will fill up faster, and Singapore will run out of space to dispose of its waste. Reducing waste extends the lifespan of the landfill and reduces environmental harm.

Marking Notes:

1 mark for identifying the limited capacity of Semakau Landfill.
1 mark for explaining the consequence (running out of space, environmental harm).

Question 18 [4 marks]

Answer (any two, 2 marks each):

(a) Reduce: The government runs campaigns encouraging people to use fewer disposable items (e.g., bringing reusable bags and containers). This reduces the amount of waste generated at the source.

(b) Recycle: Singapore provides blue recycling bins in public housing estates and encourages households to separate recyclable materials (paper, plastic, glass, metal) from general waste. These materials are collected and processed into new products, reducing the need for raw materials.

Other acceptable answers:

Reuse: Encouraging donation of usable items (clothes, furniture) to charity instead of throwing them away.
Recycle: E-waste recycling programmes for old electronics.

Marking Notes:

1 mark for identifying a valid method linked to one of the 3Rs.
1 mark for explaining how Singapore implements it.

Question 19 [4 marks]

(a) [1 mark] The recycling rate declined / decreased over the five-year period (from 61% to 57%).

Marking Notes: Accept any description that identifies a declining/decreasing trend.

(b) [2 marks] Even though total waste increased only slightly, a declining recycling rate means a larger proportion of waste is being sent to landfills instead of being recycled. This puts more pressure on Semakau Landfill, which has limited capacity. It also means more raw resources are being consumed to make new products instead of reusing existing materials, which is unsustainable.

Marking Notes:

1 mark for explaining the impact on landfill capacity.
1 mark for explaining the resource/environmental impact.

Increase public education and awareness campaigns on recycling.
Make recycling bins more accessible in all neighbourhoods.
Introduce incentives (e.g., rewards) for households that recycle more.
Implement stricter regulations on waste separation.

Marking Notes: Accept any plausible strategy.

Question 20 [5 marks]

Model Answer (agree):

I agree that sustainable resource management is everyone's responsibility because both individual actions and government policies are needed to ensure long-term sustainability.

Example 1 — Water Conservation: Individuals can play a role by practising water-saving habits such as taking shorter showers and turning off taps when not in use. If every household reduces its water consumption, the overall demand on Singapore's limited water supply decreases, helping to ensure water security for future generations. Government measures like water pricing and public education campaigns are important, but they only work if individuals take action.

Example 2 — Waste Reduction: Households can reduce waste by practising the 3Rs — for example, bringing reusable bags when shopping and recycling paper and plastic through the blue recycling bins. If individuals do not participate in recycling efforts, even the best government infrastructure will not be effective. Everyone's participation is needed to reduce the amount of waste sent to Semakau Landfill and extend its lifespan.

In conclusion, while the government sets policies and provides infrastructure, sustainable resource management ultimately depends on the daily choices and actions of every individual.

Marking Scheme:

Marks	Descriptor
5	Clear stance (agree or disagree) with well-developed explanation. Two relevant examples provided with clear links to sustainable resource management. Response is well-structured with a conclusion.
4	Clear stance with explanation. Two examples provided but links to sustainability may be less developed. Response has some structure.
3	Stance stated. One or two examples given but explanation is limited or lacks depth.
2	Stance stated but explanation is vague or only one example given without clear reasoning.
1	Stance stated but no valid examples or reasoning provided.
0	No response or completely irrelevant answer.

Marking Notes:

Award marks based on the quality of reasoning, use of examples, and clarity of argument.
Students may disagree and argue that the government/businesses bear more responsibility — accept if well-supported with examples and reasoning.
Award up to 2 marks for each well-explained example (1 mark for the example, 1 mark for the explanation linking it to sustainability).
Award 1 mark for a clear conclusion or overall argument structure.
