Secondary 4 Geography Quiz - Resources Sustainability – ANSWER KEY

Total Marks: 50


Section A: Data Interpretation and Short Response (12 marks)

1. Describe the trend in domestic water consumption between 1950 and 2020. [2]

Answer:

  • Domestic water consumption increased from 11% in 1950 to 12% in 2020. [1 mark]
  • This represents a small increase of 1 percentage point over 70 years / the increase is gradual but steady. [1 mark]

Award 1 mark for stating the direction of change (increase), and 1 mark for quantifying the change or describing the rate.


2. Suggest one reason why agricultural water consumption has remained consistently high. [2]

Answer:

  • Agriculture requires large amounts of water for irrigation to grow crops and raise livestock. [1 mark]
  • As the global population increases, more food needs to be produced, maintaining high demand for agricultural water / many crops (e.g., rice, cotton) are water-intensive. [1 mark]

Award 1 mark for identifying the reason, and 1 mark for elaboration or explanation.


3. Identify two features visible in Photograph A that help to collect and store rainwater. [2]

Answer (any two, 1 mark each):

  • Rooftop catchment / sloped roof directing water
  • Gutters or pipes channeling water
  • Storage tank / barrel / underground cistern
  • Check dam / small barrier to slow water flow
  • Percolation pit / recharge well

Award 1 mark for each correctly identified feature visible in the photograph.


4. Explain how such water harvesting systems contribute to sustainable water management. [3]

Answer:

  • Water harvesting captures rainwater that would otherwise run off, reducing reliance on groundwater or piped water supplies. [1 mark]
  • It provides a local, decentralised water source, reducing pressure on centralised water infrastructure and energy used for water treatment and distribution. [1 mark]
  • By recharging groundwater / storing water for dry periods, it helps ensure water availability for future generations, meeting the definition of sustainable development. [1 mark]

Award 1 mark for each explained point linking water harvesting to sustainability (environmental, social, or economic dimensions).


5. Using the data in Table 2, plot a pie chart to represent the types of food waste. Include a title and legend. [3]

Answer:

  • Title: “Types of Food Waste in a Singapore Neighbourhood” or similar [1 mark]
  • Accurate plotting: Rice and noodles (35% = 126°), Vegetables (28% = 101°), Meat and fish (22% = 79°), Fruits (10% = 36°), Others (5% = 18°) [1 mark for correct angles ±2° tolerance]
  • Legend: Clear labelling of each category with corresponding colour/pattern [1 mark]

Accept minor variations in angle calculation. Award full marks if pie chart is correctly proportioned, titled, and labelled.


Section B: Structured Questions (15 marks)

6. With reference to the data in Table 2, suggest one strategy to reduce food waste in Singapore households. [3]

Answer:

  • Strategy: Public education campaigns on meal planning and portion control, specifically targeting rice/noodles and vegetables which together account for 63% of food waste. [1 mark]
  • Explanation: Educating households to cook only what is needed and to store leftovers properly can reduce the amount of staple foods and vegetables thrown away. [1 mark]
  • Reference to data: Since rice/noodles (35%) and vegetables (28%) are the largest categories, targeting these would have the greatest impact on reducing overall food waste. [1 mark]

Award 1 mark for a relevant strategy, 1 mark for explanation, and 1 mark for explicit reference to the data.


7. Explain how one natural factor can affect the availability of freshwater resources in a country. [3]

Answer (example – climate/rainfall):

  • Countries with high annual rainfall (e.g., tropical regions) have abundant freshwater from rivers, lakes, and groundwater recharge. [1 mark]
  • Arid and semi-arid regions (e.g., parts of Africa, Middle East) receive low rainfall, causing water scarcity. [1 mark]
  • Seasonal distribution also matters: monsoon regions may have plenty of water in the wet season but face shortages in the dry season without storage infrastructure. [1 mark]

Accept other valid natural factors such as geology, topography, or natural vegetation cover. Award up to 3 marks for a clear explanation of how the chosen factor influences water availability.


8. Explain how another different natural factor can affect the availability of freshwater resources. [3]

Answer (example – geology/rock type):

  • Permeable rocks (e.g., limestone, sandstone) allow water to infiltrate and form groundwater aquifers, providing accessible freshwater. [1 mark]
  • Impermeable rocks (e.g., granite, shale) prevent infiltration, causing more surface runoff and reducing groundwater storage. [1 mark]
  • Geological structures such as faults and joints can create springs or artesian basins, affecting local water availability. [1 mark]

Accept any valid different factor (not the same as Question 7). Award marks for clear explanation.


9. Discuss the effectiveness of one technological solution for addressing food security challenges. [3]

Answer (example – Genetically Modified (GM) crops):

  • GM crops (e.g., Bt cotton, Golden Rice) can be engineered for drought or pest resistance, increasing yields and food availability. [1 mark]
  • This reduces crop losses and can lower the use of chemical pesticides or water. [1 mark]
  • However, high seed costs, dependence on large corporations, and potential environmental or health concerns limit their overall effectiveness, especially for small-scale farmers. [1 mark]

Award 1 mark for describing the technology, 1 mark for explaining how it helps food security, 1 mark for noting a limitation. Any well-supported technological solution (e.g., precision agriculture, vertical farming) is acceptable.


10. Discuss the effectiveness of another technological solution for addressing food security challenges. [3]

Answer (example – precision agriculture / hydroponics):

  • Precision agriculture uses sensors and GPS to optimise water and fertiliser use, increasing efficiency and reducing waste. [1 mark]
  • Hydroponics and vertical farming allow food production in urban areas with limited land, improving access and reducing transport emissions. [1 mark]
  • High initial investment, technical expertise required, and energy demands can make these solutions inaccessible to poorer communities, limiting their overall effectiveness. [1 mark]

Award 1 mark for the technology, 1 mark for food security contribution, 1 mark for a limitation. Must be a different technology from Question 9.


Section C: Data-Based Questions (12 marks)

11. Name one international agreement or organisation that has helped to promote sustainable resource management. [2]

  • The Paris Agreement (2015) under the UNFCCC. [2 marks] Also accept: CITES, Ramsar Convention, FAO, UNEP, etc. Award full marks for a correctly named and relevant example.

12. Explain how this agreement or organisation has promoted sustainable resource management. [4]

Answer (for the Paris Agreement):

  • The Paris Agreement aims to limit global temperature rise to well below 2°C, prompting countries to shift to low-carbon and sustainable energy sources. [1 mark]
  • Countries submit Nationally Determined Contributions (NDCs) that include plans to reduce emissions and adapt to climate impacts. [1 mark]
  • This promotes sustainable management by encouraging renewable energy, forest conservation, and climate-resilient agriculture. [1 mark]
  • International cooperation and climate finance help developing countries adopt cleaner technologies, reducing pressure on natural resources. [1 mark]

Award up to 4 marks for a well-developed explanation linking the agreement to sustainable resource management. The answer should demonstrate understanding of mechanisms and outcomes.


13. With reference to Figure 2, explain how the core conservation zone helps to conserve forest resources. [2]

Answer:

  • The core zone is strictly protected with no human activity allowed except research, preventing deforestation and habitat destruction. [1 mark]
  • This allows ecosystems to remain intact, preserving biodiversity and maintaining natural processes such as carbon storage and water regulation. [1 mark]

Award 1 mark for identifying the strict protection, 1 mark for explaining the conservation benefit.


14. With reference to Figure 2, explain how the buffer or transition zone helps to conserve forest resources. [2]

Answer:

  • The buffer zone allows limited, sustainable activities (e.g., ecotourism, non-timber forest products) that provide livelihoods without degrading the core forest. [1 mark]
  • The transition zone permits controlled agriculture, which reduces pressure on the core area by providing food and income, while still acting as a protective boundary. [1 mark]

Award 1 mark for describing the allowed activities, 1 mark for explaining how this helps protect the core forest.


15. Describe the trend in renewable energy consumption shown in Figure 3. [2]

Answer:

  • Renewable energy consumption has increased steadily from 6% in 1990 to 13% in 2020. [1 mark]
  • The rise was gradual, with the most significant growth occurring between 2010 and 2020. [1 mark]

Award 1 mark for stating the overall increase, 1 mark for highlighting the pace or period of growth.


Section D: Discussion and Evaluation (11 marks)

16. Give two reasons why creating protected areas is an effective way to ensure resource sustainability. [4]

Answer (two from the following, 2 marks each):

  1. Protected areas preserve biodiversity and ecosystem services (e.g., water catchment, pollination) that are essential for long-term resource availability. [2 marks]
  2. They prevent overexploitation by limiting logging, hunting, and mining, allowing resources (timber, wildlife) to regenerate. [2 marks]
  3. They can support ecotourism, providing economic incentives to keep ecosystems intact rather than converting them for short-term gain. [2 marks]

Award 2 marks for each well-explained reason. Max 4 marks.


17. State one limitation of relying solely on creating protected areas for resource sustainability. [2]

Answer (example):

  • Protected areas can displace local communities who depend on the land for their livelihoods, leading to conflict and illegal resource extraction. [2 marks]

Award 2 marks for a clearly stated limitation with brief explanation. Other valid points: limited coverage, lack of enforcement, climate change impacts, etc.


**18. State another limitation of relying solely on creating protected areas for resource sustainability. [

Answer (any two, 2 marks each):

  • Biodiversity conservation: Protected areas preserve habitats for endangered species, maintaining genetic diversity which is essential for ecosystem resilience and future resources (e.g., potential medicines, crop wild relatives). [2 marks]
  • Ecosystem services protection: Forests in protected areas regulate water cycles, prevent soil erosion, and sequester carbon, ensuring the long-term availability of clean water and fertile soil. [2 marks]
  • Legal enforcement: Protected areas have legal status that prohibits or restricts extractive activities, providing a clear framework for conservation and enabling monitoring and enforcement. [2 marks]

Award 1 mark for stating the reason, and 1 mark for elaboration on how it leads to resource sustainability.


17. State one limitation of relying solely on creating protected areas for resource sustainability. [2]

Answer (any one):

  • Protected areas can displace indigenous and local communities, leading to conflicts and loss of traditional livelihoods, which may undermine long-term conservation if communities are hostile. [2 marks]
  • Many protected areas are “paper parks” with inadequate funding, staffing, and enforcement, making them ineffective against illegal logging, poaching, or encroachment. [2 marks]
  • Protected areas cover only a small fraction of the Earth’s surface and may not protect resources that are widely distributed or migratory (e.g., marine fish stocks, migratory birds). [2 marks]

Award 1 mark for identifying the limitation, and 1 mark for explaining why it reduces effectiveness.


18. State another limitation of relying solely on creating protected areas for resource sustainability. [2]

Answer (any one, different from Q17):

  • Climate change can alter habitats within protected areas (e.g., shifting temperature and rainfall patterns), making them unsuitable for the species they were designed to protect, and boundaries cannot easily be moved. [2 marks]
  • Protected areas do not address the root causes of resource depletion, such as overconsumption, poverty, or market demand for timber and wildlife products, which continue outside their boundaries. [2 marks]
  • Strict protection can sometimes lead to increased pressure on surrounding unprotected areas, a phenomenon known as “leakage” or “spillover.” [2 marks]

Award 1 mark for identifying the limitation, and 1 mark for explaining why it reduces effectiveness.
