A-Level Geography H2 Quiz - Resources Sustainability: Answer Key and Marking Scheme

Total Marks: 50

Section A: Short Answer Questions (10 marks)

1. Define the term "resource sustainability" and explain why it is a central concern in contemporary geography. [2]

Answer: Resource sustainability refers to the use and management of natural resources in ways that meet present needs without compromising the ability of future generations to meet their own needs. It involves balancing economic, social, and environmental considerations to ensure resources remain available and productive over the long term.

It is a central concern in contemporary geography because:

Growing global population and rising consumption levels are placing unprecedented pressure on finite resources.
Climate change is altering the availability and distribution of resources, particularly water and agricultural land.
Geographers study the spatial dimensions of resource use, distribution, and management, making sustainability a core disciplinary focus.

Marking Scheme:

1 mark for accurate definition (must include intergenerational equity or meeting present and future needs).
1 mark for explanation of why it is a central concern (must reference population pressure, climate change, or spatial analysis).

2. Distinguish between renewable and non-renewable resources, providing one example of each. [2]

Answer: Renewable resources are those that can be replenished naturally over relatively short timescales, such that they are not depleted if used at or below their rate of regeneration. Example: solar energy, wind energy, timber (from sustainably managed forests), or freshwater (within the hydrological cycle).

Non-renewable resources exist in finite quantities and are formed over geological timescales far exceeding human lifespans. Once extracted and used, they cannot be replaced within meaningful human timeframes. Example: fossil fuels (coal, oil, natural gas), minerals (copper, iron ore), or fossil groundwater.

Marking Scheme:

1 mark for clear distinction between the two types (must reference replenishment rate or timescale).
1 mark for one appropriate example of each (2 examples total, 0.5 marks each).

3. State two environmental consequences of over-extraction of groundwater resources. [2]

Answer: Any two of the following:

Land subsidence: As groundwater is removed, pore spaces in aquifers collapse, causing the land surface to sink. This can damage infrastructure and increase flood risk (e.g., Jakarta has subsided by up to 4 metres in some areas).
Saltwater intrusion: In coastal areas, over-extraction reduces freshwater pressure, allowing saline water to infiltrate aquifers, rendering them unusable for drinking or irrigation.
Depletion of surface water bodies: Groundwater often feeds rivers, lakes, and wetlands. Over-extraction can reduce baseflow, causing streams to dry up and wetland ecosystems to degrade.
Reduced water quality: Lowering of the water table can concentrate contaminants and allow pollutants from the surface to reach deeper aquifers more easily.

Marking Scheme:

1 mark for each valid environmental consequence (2 consequences required).
Consequences must be environmental (not economic or social).
Accept any two clearly stated consequences with brief explanation.

4. Identify two key principles of sustainable resource management. [2]

Answer: Any two of the following:

Intergenerational equity: Ensuring that future generations have access to resources at least equivalent to those available to the present generation.
Precautionary principle: Where there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason to postpone cost-effective measures to prevent environmental degradation.
Polluter pays principle: Those who produce pollution should bear the costs of managing it to prevent damage to human health or the environment.
Maximum sustainable yield: Renewable resources should be harvested at a rate no greater than their rate of natural regeneration.
Integrated resource management: Resources should be managed holistically, considering interactions between different resources and sectors (e.g., water-energy-food nexus).

Marking Scheme:

1 mark for each correctly identified principle (2 principles required).
Principles must be named and briefly explained.

5. Explain what is meant by the term "carrying capacity" in the context of resource use. [2]

Answer: Carrying capacity refers to the maximum population size that an environment or area can support indefinitely, given the available resources (food, water, energy, space) and the capacity of the environment to absorb waste products without degradation. In the context of resource use, it represents the limit beyond which resource consumption exceeds the rate of resource renewal or waste assimilation, leading to environmental degradation and resource depletion. When a population exceeds carrying capacity, overshoot occurs, potentially leading to resource collapse unless mitigated by technological innovation, resource imports, or population decline.

Marking Scheme:

1 mark for defining carrying capacity as the maximum sustainable population or resource use level.
1 mark for explaining the concept in relation to resource limits, renewal rates, or consequences of exceeding capacity.

Section B: Data Response Questions (20 marks)

6. Using Resource 1, describe the pattern of global freshwater withdrawal by sector. [3]

Answer: Resource 1 shows that agriculture is the dominant sector for global freshwater withdrawal, accounting for 70% of total withdrawals. This is more than three times the share of the next largest sector. Industry accounts for 20% of withdrawals, while domestic/municipal use represents the smallest share at only 10%. The data indicates that agricultural water use is the primary driver of global freshwater demand, with industrial and domestic uses being comparatively minor components of total withdrawal.

Marking Scheme:

1 mark for identifying agriculture as the dominant sector (70%).
1 mark for providing comparative data for all three sectors.
1 mark for using comparative language (e.g., "more than three times," "the smallest share").
Award marks for accurate description; do not require explanation or analysis.

7. Using Resources 2 and 3, identify which country faces "absolute water scarcity" and explain the implications of this classification for its resource sustainability. [4]

Answer: Saudi Arabia faces absolute water scarcity, with only 80 m³ of per capita renewable freshwater per year, which is well below the 500 m³ threshold for absolute water scarcity as shown in Resource 3.

Implications for resource sustainability include:

Extreme dependence on non-renewable groundwater extraction or energy-intensive desalination, both of which have significant environmental and economic costs.
High vulnerability to water shortages, which can constrain economic development, agricultural production, and quality of life.
Potential for water-related conflicts, particularly in a region where water resources are shared across borders.
Need for demand management strategies such as water pricing, conservation measures, and wastewater recycling to achieve any degree of sustainability.
Food security concerns, as domestic agriculture is severely constrained, leading to heavy reliance on food imports (virtual water trade).

Marking Scheme:

1 mark for correctly identifying Saudi Arabia.
1 mark for referencing the threshold (below 500 m³/person/year).
2 marks for explaining implications (2 well-developed points, 1 mark each).
Implications must link to resource sustainability.

8. Compare the per capita renewable freshwater resources of Brazil and India as shown in Resource 2. Suggest one physical and one human factor that may account for this difference. [5]

Answer: Brazil has 42,000 m³/person/year, which is 28 times greater than India's 1,500 m³/person/year. Brazil's water availability places it well above the "no stress" threshold (>1,700), while India falls within the "water stress" classification (1,000–1,700).

Physical factor: Brazil contains a large portion of the Amazon Basin, which receives high annual rainfall and hosts the world's largest river system by discharge volume, resulting in abundant renewable freshwater resources. In contrast, India's climate is dominated by the monsoon, which is highly seasonal and spatially variable, with many semi-arid regions receiving limited rainfall.

Human factor: India's population of over 1.4 billion is significantly larger than Brazil's approximately 215 million, meaning that even though India has substantial total water resources, the per capita availability is drastically reduced by the sheer number of people sharing those resources.

Marking Scheme:

1 mark for accurate comparison using data from Resource 2.
1 mark for referencing the water stress classification.
1 mark for a valid physical factor with explanation.
1 mark for a valid human factor with explanation.
1 mark for clear linkage between the factors and the difference in per capita availability.

9. With reference to Resources 1, 2, and 3, explain why water resource management requires different strategies in different countries. Support your answer with evidence from the resources. [5]

Answer: Water resource management must be context-specific because countries face vastly different water availability, sectoral demands, and stress levels.

Evidence from resources:

Resource 2 shows extreme variation in per capita water availability, from Brazil (42,000 m³) to Saudi Arabia (80 m³). A water-abundant country like Brazil may focus on water quality and flood management, while Saudi Arabia must prioritise supply augmentation through desalination and stringent demand management.
Resource 1 indicates that agriculture dominates global water use (70%), but this varies by country. Industrialised nations may have higher industrial water demand, while agrarian economies need strategies focused on irrigation efficiency.
Resource 3 classifies countries into stress categories. India (1,500 m³) is in "water stress" and needs conservation and efficiency measures. Singapore (130 m³) faces "absolute water scarcity" and has developed a diversified strategy including NEWater, desalination, and water import agreements. Saudi Arabia (80 m³) relies heavily on desalination and fossil groundwater.
Different strategies are also required due to economic capacity. Wealthier water-scarce nations (Singapore, Saudi Arabia) can invest in capital-intensive technology, while poorer nations may need community-based management and international aid.

Marking Scheme:

1 mark for clear statement that strategies must be context-specific.
3 marks for evidence-based explanation using all three resources (1 mark per resource effectively used).
1 mark for synthesising the argument with reference to different national circumstances.

10. Evaluate the usefulness of per capita water availability data (as shown in Resource 2) as a measure of water resource sustainability. [3]

Answer: Per capita water availability data is useful because it provides a standardised, comparable measure of water endowment relative to population, allowing classification of countries into stress categories (Resource 3) and identification of potential scarcity issues. It highlights the pressure that population places on water resources.

However, it has limitations:

It masks internal spatial variations; a national average may conceal severe regional scarcity (e.g., northern China vs. southern China).
It does not account for water quality, infrastructure, or access; a country may have high per capita availability but poor water quality or inadequate distribution systems.
It ignores transboundary water flows and dependence on external sources (e.g., Singapore imports water from Malaysia).
It does not reflect consumption patterns, virtual water trade, or technological capacity to augment supply through desalination or recycling.

Marking Scheme:

1 mark for identifying at least one strength of the measure.
1 mark for identifying at least one limitation.
1 mark for a balanced evaluation or conclusion on its overall usefulness.

Section C: Structured Essay Questions (20 marks)

11. Explain how climate change is expected to affect the sustainability of freshwater resources. [6]

Answer: Climate change affects freshwater sustainability through multiple interconnected mechanisms:

Altered precipitation patterns: Climate change is intensifying the hydrological cycle, leading to increased precipitation in some regions (higher latitudes, some tropics) and decreased precipitation in others (subtropics, Mediterranean regions). This changes the spatial distribution of renewable freshwater, exacerbating water stress in already dry regions.
Increased evaporation: Higher temperatures increase evaporation rates from surface water bodies and soil, reducing available freshwater and increasing irrigation demands.
Glacial melt and changed snowmelt timing: Many rivers (e.g., Ganges, Yangtze) depend on glacial meltwater. As glaciers retreat, short-term flows may increase, but long-term water security is threatened as glacial storage diminishes. Earlier snowmelt alters seasonal flow regimes.
Sea level rise and saltwater intrusion: Rising sea levels increase saltwater intrusion into coastal aquifers and estuaries, reducing freshwater availability in densely populated coastal areas (e.g., Mekong Delta, Bangladesh).
Increased frequency and intensity of extreme events: More frequent droughts reduce water availability and recharge, while intense rainfall and flooding can damage water infrastructure and contaminate supplies.
Impacts on water quality: Higher water temperatures can promote algal blooms and reduce dissolved oxygen, affecting water quality for human and ecosystem use.

Case study example: The Murray-Darling Basin in Australia has experienced reduced inflows due to declining rainfall linked to climate change, threatening agricultural sustainability and ecosystem health.

Marking Scheme:

Level 3 (5–6 marks): Comprehensive explanation of multiple mechanisms with clear links to sustainability. Use of specific examples or case studies.
Level 2 (3–4 marks): Explanation of some mechanisms with partial links to sustainability. Limited use of examples.
Level 1 (1–2 marks): Basic identification of effects without clear explanation or linkage to sustainability.

12. "Technological innovation alone can solve the world's resource sustainability challenges." Discuss this statement with reference to either energy resources or water resources. [8]

Answer: [Answer will vary based on student's choice of energy or water resources. A model answer for water resources is provided.]

Technological innovations have made significant contributions to water resource sustainability:

Desalination technology (e.g., reverse osmosis) has enabled water-scarce countries like Saudi Arabia, Israel, and Singapore to augment freshwater supplies. Singapore's desalination plants meet up to 30% of its water needs.
Water recycling and reuse technologies, such as Singapore's NEWater, treat wastewater to high standards for industrial and indirect potable use, reducing pressure on freshwater sources.
Precision agriculture technologies, including drip irrigation and soil moisture sensors, have dramatically improved water use efficiency in agriculture (e.g., Israel's agricultural water productivity).
Leak detection and smart water grids reduce non-revenue water losses in urban distribution systems.

However, technological innovation alone is insufficient:

Economic barriers: Advanced technologies are capital-intensive and often unaffordable for developing countries. Desalination remains energy-intensive and expensive.
Social and behavioural factors: Technology cannot address overconsumption patterns or the tragedy of the commons without accompanying changes in behaviour, water pricing, and governance.
Environmental constraints: Desalination produces brine discharge that harms marine ecosystems. Technology may create new environmental problems.
Political and institutional factors: Effective water management requires strong governance, transboundary cooperation, and integrated planning that technology alone cannot provide.
Equity concerns: Technology may exacerbate inequalities if access is limited to wealthy populations or countries.

A holistic approach combining technological innovation with demand management, policy reform, community engagement, and international cooperation is necessary. Singapore's water strategy exemplifies this integration, combining technology (NEWater, desalination) with pricing, public education, and catchment management.

Marking Scheme:

Level 4 (7–8 marks): Balanced, well-argued discussion with specific examples. Clear evaluation of the statement with a justified conclusion.
Level 3 (5–6 marks): Good discussion with examples, some balance between arguments for and against.
Level 2 (3–4 marks): Some relevant points but limited balance or examples. Descriptive rather than analytical.
Level 1 (1–2 marks): Basic points with little development or exemplification.

13. Assess the view that the sustainable management of tropical forest resources requires the involvement of local communities more than government regulation. [6]

Answer: Arguments supporting the primacy of local community involvement:

Local communities possess indigenous knowledge of forest ecosystems, species, and sustainable harvesting practices accumulated over generations (e.g., shifting cultivation cycles, non-timber forest product harvesting).
Community-based forest management (CBFM) creates direct economic incentives for conservation, as communities benefit from sustainable use (e.g., eco-tourism, sustainable timber, NTFPs like Brazil nuts, rattan).
Local communities are often the most directly affected by deforestation and degradation, giving them a strong stake in long-term sustainability.
Top-down government regulation has often failed due to lack of enforcement capacity, corruption, and alienation of local people (e.g., fortress conservation approaches that exclude communities).
Successful examples include community forestry in Nepal, where forest user groups have reversed deforestation, and extractive reserves in Brazil where rubber tappers manage forests sustainably.

However, government regulation remains essential:

Governments provide legal frameworks, land tenure security, and enforcement against illegal logging, encroachment, and large-scale commercial exploitation that communities cannot resist alone.
National and international policies (e.g., REDD+, FLEGT, CITES) require government participation and coordination.
Governments can provide resources, technical support, and market access that communities may lack.
Without government backing, community management can be undermined by external actors (e.g., mining companies, agribusiness).

Conclusion: The most effective approach integrates community involvement with supportive government regulation. Neither alone is sufficient; they are complementary. The view is partially valid in that community involvement is indispensable, but it overstates the case by diminishing the essential role of government.

Marking Scheme:

Level 3 (5–6 marks): Balanced assessment with specific examples. Clear evaluation of the relative importance of community involvement and government regulation.
Level 2 (3–4 marks): Some assessment with limited examples. Partial balance between the two perspectives.
Level 1 (1–2 marks): One-sided argument or general statements without specific exemplification.
