Read the following extract and answer Questions 11–15.
Extract A: Water Scarcity in Cape Town, South Africa
In 2018, Cape Town faced an unprecedented water crisis known as "Day Zero" — the day when the city's municipal water supply would be largely shut off. Years of below-average rainfall, a growing population, and aging infrastructure pushed dam levels below 20%. The city implemented strict water restrictions, limiting each resident to 50 litres per day. Agriculture, which consumed approximately 30% of the region's water, was also heavily affected. The crisis highlighted the vulnerability of cities to water stress and the urgent need for sustainable water management strategies, including desalination plants, groundwater extraction, and water recycling.

Secondary 4 Geography Quiz - Resources Sustainability
Answer Key
Section A: Short Answer Questions
1. Define the term renewable resource. Give one example. [2]
- A renewable resource is a natural resource that can be replenished naturally over a short period of time / at a rate comparable to or faster than its rate of consumption. [1]
- Example: solar energy / wind energy / timber (from sustainably managed forests) / water (hydrological cycle) / tidal energy. [1]
Marking note: Award 1 mark for a correct definition and 1 mark for a valid example. Accept any reasonable renewable resource.
2. State two reasons why global demand for water has increased over the past 50 years. [2]
(a) Population growth / increase in global population leading to greater domestic water use. [1]
(b) Industrialisation / expansion of agriculture (irrigation) / rising standards of living / urbanisation. [1]
Marking note: Award 1 mark for each valid reason, up to 2 marks. Answers must be distinct.
3. What is meant by sustainable development? [2]
- Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. [2]
Marking note: Award 2 marks for a complete definition that includes both present and future generations. Award 1 mark for a partial answer (e.g., only mentions "meeting present needs" or only "not harming the future").
4. State one advantage and one disadvantage of using solar energy as a resource. [2]
Advantage: It is renewable / does not produce greenhouse gas emissions during operation / abundant in sunny regions / low running costs after installation. [1]
Disadvantage: It is intermittent / depends on weather and daylight / high initial cost of solar panels / requires large land area for solar farms / energy storage technology is still developing. [1]
Marking note: Award 1 mark for each valid and distinct point.
5. Name two strategies a government can use to manage the depletion of non-renewable resources. [2]
(a) Invest in / subsidise renewable energy alternatives. [1]
(b) Implement conservation policies / impose taxes or quotas on extraction / promote recycling / fund research into alternative materials / regulate extraction rates. [1]
Marking note: Award 1 mark for each valid strategy. Answers must be distinct.
Section B: Data and Source-Based Questions
6. Describe the trend in global coal consumption between 1990 and 2020. [2]
- Global coal consumption increased steadily from 2,200 million tonnes of oil equivalent in 1990 to 3,800 million tonnes of oil equivalent in 2020. [1]
- The rate of increase accelerated after 2000, with a particularly sharp rise between 2000 and 2010 (from 2,300 to 3,600). [1]
Marking note: Award 1 mark for identifying the overall increase. Award 1 mark for describing the pattern/rate of change with reference to data. Answers must reference Figure 1.
7. Calculate the increase in natural gas consumption (in million tonnes of oil equivalent) from 1990 to 2020. Show your working. [2]
- Working: 3,300 − 1,800 = 1,500 [1]
- Answer: 1,500 million tonnes of oil equivalent [1]
Marking note: Award 1 mark for correct working and 1 mark for correct answer. If the answer is correct but no working is shown, award 1 mark only.
8. Which fossil fuel showed the greatest increase in consumption between 1990 and 2020? Support your answer with evidence from Figure 1. [2]
- Coal showed the greatest increase. [1]
- Coal consumption increased by 1,600 million tonnes of oil equivalent (from 2,200 to 3,800), compared to oil (increase of 1,000, from 3,100 to 4,100) and natural gas (increase of 1,500, from 1,800 to 3,300). [1]
Marking note: Award 1 mark for correct identification. Award 1 mark for supporting data comparison. Accept natural gas if the student argues based on percentage increase (natural gas increased by ~83% vs coal by ~73%), but the expected answer is coal based on absolute increase.
9. Suggest two environmental consequences of the continued reliance on fossil fuels shown in Figure 1. [2]
(a) Increased greenhouse gas emissions (CO₂) leading to global warming / climate change. [1]
(b) Air pollution (e.g., smog, acid rain) / ocean acidification / habitat destruction from mining/drilling. [1]
Marking note: Award 1 mark for each valid environmental consequence. Answers must be distinct.
10. Explain why some countries continue to rely heavily on fossil fuels despite their environmental impacts. [2]
- Fossil fuels are relatively cheap and abundant in many countries / existing infrastructure is built around fossil fuels, making transition costly. [1]
- Developing countries may prioritise economic growth and industrialisation over environmental concerns / renewable energy technology may be expensive or inaccessible for some nations. [1]
Marking note: Award 1 mark for each valid explanation, up to 2 marks. Answers must show reasoning, not just restate the question.
11. According to Extract A, what was "Day Zero"? [1]
- The day when Cape Town's municipal water supply would be largely shut off. [1]
Marking note: Award 1 mark for a correct answer that refers to the shutdown of water supply. Accept close paraphrasing.
12. State two causes of Cape Town's water crisis mentioned in Extract A. [2]
(a) Years of below-average rainfall / drought. [1]
(b) Growing population / aging infrastructure. [1]
Marking note: Award 1 mark for each valid cause directly from the extract. Answers must be from Extract A.
13. How did the water restrictions affect the daily lives of Cape Town residents? [1]
- Each resident was limited to 50 litres of water per day, significantly restricting their daily water use for drinking, cooking, washing, and sanitation. [1]
Marking note: Award 1 mark for a valid answer referencing the 50-litre limit and its impact.
14. Using Extract A, explain why agriculture was particularly affected by the water crisis. [2]
- Agriculture consumed approximately 30% of the region's water supply. [1]
- When water restrictions were imposed, the agricultural sector faced significant reductions in water allocation, affecting crop production and livelihoods. [1]
Marking note: Award 1 mark for referencing the 30% figure from the extract. Award 1 mark for explaining the impact on agriculture.
15. Besides the strategies mentioned in Extract A, suggest one additional strategy Cape Town could adopt to improve its water sustainability. Explain your answer. [2]
- Strategy: Implement rainwater harvesting systems across the city. [1]
- Explanation: Collecting and storing rainwater during wet seasons would provide an additional water source, reducing reliance on dams and groundwater, and increasing the city's resilience to drought. [1]
Marking note: Award 1 mark for a valid strategy not mentioned in Extract A. Award 1 mark for a clear explanation of how it improves water sustainability. Accept other valid answers (e.g., fixing leaky infrastructure, public education campaigns, water-efficient irrigation for agriculture).
Section C: Structured Response Questions
16. Explain two ways in which deforestation can negatively affect the sustainability of forest resources. [4]
(a) Deforestation leads to soil erosion / loss of soil fertility. [1] When tree roots are removed, the soil is no longer held together and is easily washed away by rain. [1] This reduces the land's ability to support future forest growth, making the resource unsustainable.
(b) Deforestation reduces biodiversity / destroys habitats. [1] Many plant and animal species depend on forest ecosystems for survival. When forests are cleared, species may become extinct, disrupting ecological balance and reducing the long-term productivity and resilience of the forest resource. [1]
Marking note: Award 1 mark for identifying each way and 1 mark for explaining each way (2 + 2 = 4 marks). Accept other valid answers such as: disruption of the water cycle, contribution to climate change (reduced carbon sink), loss of livelihoods for indigenous communities.
17. Describe two methods of conserving fish stocks in the world's oceans. [4]
(a) Impose fishing quotas / set catch limits. [1] Governments and international bodies can set maximum allowable catch sizes for specific fish species to prevent overfishing and allow populations to replenish. [1]
(b) Establish marine protected areas (MPAs) / no-fishing zones. [1] Designating certain areas of the ocean as protected zones where fishing is banned or restricted allows fish populations to recover and ecosystems to regenerate. [1]
Marking note: Award 1 mark for identifying each method and 1 mark for describing each method (2 + 2 = 4 marks). Accept other valid answers such as: banning destructive fishing practices (e.g., bottom trawling), enforcing minimum net mesh sizes, promoting aquaculture, seasonal fishing bans during breeding periods.
18. Explain how the use of renewable energy sources can contribute to resource sustainability. [4]
- Renewable energy sources such as solar, wind, and hydroelectric power are naturally replenished and will not run out, unlike fossil fuels which are finite. [1]
- They produce little or no greenhouse gas emissions during operation, reducing air pollution and mitigating climate change. [1]
- By reducing dependence on non-renewable resources, renewable energy helps conserve fossil fuels for future generations. [1]
- The development of renewable energy infrastructure can also create jobs and promote economic sustainability in the long term. [1]
Marking note: Award 1 mark for each valid explanation point, up to 4 marks. Answers should demonstrate understanding of the link between renewable energy and sustainability. Accept other valid points.
19. "Recycling alone is not enough to achieve resource sustainability." Discuss this statement with reference to at least two examples. [4]
- Recycling is an important strategy as it reduces the need for raw material extraction and decreases waste sent to landfills. For example, recycling aluminium cans uses 95% less energy than producing new aluminium from bauxite ore. [1]
- However, recycling alone is insufficient because not all materials can be recycled indefinitely — for example, paper fibres degrade after several cycles and eventually become unusable. [1]
- Additionally, recycling does not address overconsumption. For example, even with high plastic recycling rates, the production of single-use plastics continues to grow, leading to pollution of oceans and ecosystems. [1]
- A comprehensive approach is needed, including reducing consumption (e.g., using reusable products), reusing materials, and developing sustainable alternatives, alongside recycling. [1]
Marking note: Award up to 4 marks for a balanced discussion with at least two examples. Award 1 mark for each well-developed point. Answers should show evaluation, not just description. Lifting the quality of discussion can earn higher marks.
20. Evaluate the effectiveness of international agreements in managing global resource sustainability. In your answer, refer to at least one specific agreement or initiative. [4]
- International agreements such as the Paris Agreement (2015) aim to limit global warming to well below 2°C by reducing greenhouse gas emissions. [1]
- These agreements are effective in raising global awareness and setting common targets, encouraging countries to develop national policies for sustainability. For example, many countries have committed to net-zero emissions targets as a result. [1]
- However, effectiveness is limited because agreements are often non-compliant / lack enforcement mechanisms. Some countries fail to meet their pledges, and there are no strict penalties for non-compliance. [1]
- Additionally, disagreements between developed and developing nations over responsibility and funding can hinder progress. For example, developing countries argue that developed nations, having historically contributed more to emissions, should bear a greater share of the costs. [1]
- Overall, international agreements are a necessary but insufficient tool — they must be complemented by national action, technological innovation, and changes in individual behaviour to achieve meaningful resource sustainability. [0 — bonus evaluative conclusion, not separately marked but contributes to overall quality]
Marking note: Award up to 4 marks. Award 1 mark for referencing a specific agreement, 1 mark for explaining effectiveness, 1 mark for explaining limitations, and 1 mark for an evaluative conclusion. Accept other valid agreements (e.g., Montreal Protocol, Kyoto Protocol, Convention on Biological Diversity).
