Image pending generation: diagram for Q8.

With reference to the diagram, explain how the Four National Taps improve water sustainability in Singapore. [4]

9. State two environmental problems caused by the overuse of fossil fuels. [2]

10. Explain how reducing food waste can contribute to resource sustainability. [3]

11. Study the graph below showing household recycling rates in Singapore from 2018 to 2023.

Describe the trend shown in the graph. [2]

12. Suggest one reason for the trend described in Question 11. [2]

13. Explain the concept of a "circular economy" and how it supports sustainability. [3]

14. Study the map below showing designated green spaces and reservoirs in a fictional city.

Image pending generation: map for Q14.

With reference to the map, explain how protected green spaces and reservoirs can support resource sustainability in the city. [4]

15. Give two advantages of using solar energy in Singapore. [2]

Section C: Data-Based and Extended Response (Questions 16–20) — 10 marks

16. Study the data below on land used for agriculture in Singapore (in hectares).

Year	Agri Land (ha)
2015	620
2018	720
2021	810
2023	860

Plot a line graph of the data on the grid provided. [3]

(Grid not shown; student to draw axes: x = Year, y = Agri Land ha, scale 0–900)

17. Using the graph from Question 16, calculate the percentage increase in agricultural land from 2015 to 2023. Show your working. [2]

18. "Singapore should rely fully on imported food because local production is too costly." Do you agree? Explain your view with reasons. [3]

19. Study the extract below.

Singapore imports over 90% of its food. To reduce dependence, the government aims for 30% of nutritional needs to be locally produced by 2030 ("30 by 30" goal).

With reference to the extract, explain why the "30 by 30" goal improves resource sustainability. [2]

20. Suggest two challenges Singapore may face in achieving the "30 by 30" goal and explain one strategy to overcome each. [3]

Secondary 4 Geography Quiz - Resources Sustainability (Answer Key)

Total Marks: 40
Section A (Q1–5): 10 marks
Section B (Q6–15): 20 marks
Section C (Q16–20): 10 marks

Section A: Basic Understanding

Q1. [2 marks]
Definition: Sustainable development means meeting the needs of the present generation without compromising the ability of future generations to meet their own needs.
Marking: 1 mark for "present needs", 1 mark for "not compromising future".
Teaching note: From Brundtland Report; core geography concept. Do not just say "save the Earth" — must include both present and future.

Q2. [2 marks]
Any two: (1) Limited land area for agriculture; (2) No natural water sources so reliant on imports; (3) Small local production cannot feed population.
Marking: 1 mark each, max 2.
Common mistake: Stating "we are rich" — not a risk, must be specific vulnerability.

Q3. [2 marks]
Renewable: solar/wind/hydro; Non-renewable: coal/oil/natural gas.
Marking: 1 mark each type correct.

Q4. [2 marks]
A water catchment is an area where rain is collected and channelled to reservoirs for storage and treatment. In Singapore, catchments like MacRitchie collect rainwater for drinking.
Marking: 1 mark definition, 1 mark Singapore context.

Q5. [2 marks]
E.g., using LED lights, air-con at 25°C, switching off appliances.
Marking: 1 mark for valid action, 1 mark for household context.

Section B: Structured Response

Q6. [3 marks]
Answer: Over-reliance on Malaysia (28%) and Indonesia (19%) means if exports stop due to conflict or climate shock, supply drops. Concentration increases vulnerability.
Marking: 1 mark identify concentration risk; 1 mark explain disruption; 1 mark link to food security.
Teaching: Use data — 47% from two neighbours.

Q7. [4 marks]
(1) Vertical farming / rooftop farms to use limited land; (2) Research in aquaculture / lab-grown meat.
Marking: 2 marks each strategy with explanation.
Note: Must be Singapore-specific.

Q8. [4 marks]
With ref to diagram: Four sources diversify supply so no single source fails. NEWater and desalination reduce rain dependence. Local catchment uses rain.
Marking: 1 mark diversity; 1 mark NEWater; 1 mark desalination; 1 mark local catchment.
Visual needed: Diagram shows 4 arrows to central box.

Q9. [2 marks]
Any two: air pollution, global warming, oil spills.
Marking: 1 mark each.

Q10. [3 marks]
Less waste = less landfil, less production energy, resources used efficiently.
Marking: 1 mark each point up to 3.

Q11. [2 marks]
Trend: Recycling rate rose slowly from 22% (2018) to 27% (2023).
Marking: 1 mark state increase; 1 mark values.

Q12. [2 marks]
E.g., education campaigns, fines for littering.
Marking: 1 mark reason, 1 mark explain.

Q13. [3 marks]
Circular economy = reuse/repair/ recycle to keep materials in use. Reduces waste and new resource need.
Marking: 1 def, 1 explain, 1 link sustainability.

Q14. [4 marks]
Green spaces absorb rain, cool city, reservoirs store water. Map shows planned distribution.
Marking: 1 mark each: green spaces, reservoirs, map evidence, sustainability link.

Q15. [2 marks]
E.g., clean energy, land-efficient (on roofs).
Marking: 1 mark each.

Section C: Data-Based and Extended Response

Q16. [3 marks]
Graph: x-year, y-ha, plot 4 points, join line.
Marking: 1 axes+scale, 1 points, 1 line.

Q17. [2 marks]
Increase = (860-620)/620 ×100 = 38.7%.

Marking: 1 correct method, 1 answer.

Q18. [3 marks]
Disagree: local gives buffer, import risk. Agree: cost. Balanced view needed.
Marking: 1 view, 2 reasons.

Q19. [2 marks]
