Answer Key and Marking Scheme

Subject: Geography H1 Level: A-Level Paper: Practice Paper 2 (Resources & Sustainability Focus) Total Marks: 100

Section A: Data Response Questions (60 marks)

Question 1: Resource Consumption and Sustainability (22 marks)

(a) Describe the trends in global water withdrawal by sector from 1900 to 2025 as shown in Resource 1A. [4]

Answer:

Total global water withdrawal has increased significantly from 560 km³ in 1900 to a projected 4,900 km³ in 2025, an increase of nearly nine times. [1]
Agriculture has consistently been the largest water-consuming sector, increasing from 500 km³ to a projected 3,200 km³. [1]
Industrial water withdrawal has grown rapidly, from 40 km³ to a projected 1,200 km³, representing the fastest relative growth rate. [1]
Domestic water withdrawal has also increased, from 20 km³ to a projected 500 km³, reflecting population growth and rising living standards. [1]

Marking notes: Award 1 mark for each valid trend with supporting data. Accept alternative valid observations (e.g., the gap between sectors has widened).

(b) With reference to Resource 1B, describe the spatial distribution of areas experiencing high water stress. [4]

Answer:

High water stress is concentrated in a band across North Africa and the Middle East, extending from Morocco to Iran. [1]
Central Asia, including countries such as Uzbekistan and Kazakhstan, also experiences high water stress. [1]
Parts of South Asia, particularly western India and Pakistan, are classified as high water stress. [1]
Other areas include the western United States and parts of southern Africa. [1]

Marking notes: Award 1 mark for each valid spatial observation with specific location reference. Accept use of directional language (e.g., "between 15°N and 40°N latitude").

(c) Explain two factors that account for the high water stress in regions shown in Resource 1B. [6]

Answer: Factor 1: Arid and semi-arid climate (3 marks)

Many high water stress regions are located in arid or semi-arid climate zones with low annual precipitation (e.g., North Africa, Middle East). [1]
High temperatures lead to high evapotranspiration rates, reducing available surface water and soil moisture. [1]
These climatic conditions mean natural water availability is inherently limited, making these regions vulnerable to water stress even with moderate demand. [1]

Factor 2: High population growth and agricultural demand (3 marks)

Many high water stress regions have rapidly growing populations, increasing domestic water demand. [1]
Agriculture in these regions often relies on irrigation, which accounts for a high proportion of water withdrawal (e.g., over 80% in parts of South Asia and the Middle East). [1]
Inefficient irrigation practices, such as flood irrigation, lead to significant water losses through evaporation and runoff, exacerbating water stress. [1]

Marking notes: Award up to 3 marks per factor. Accept other valid factors such as industrial demand, groundwater depletion, transboundary water conflicts, or climate change impacts. Must include explanation, not just identification.

(d) Using Resources 1A and 1B, evaluate the usefulness of these resources in helping to understand the global challenge of water sustainability. [8]

Answer: Usefulness of Resource 1A:

Provides quantitative data on water withdrawal trends over time, showing the scale and trajectory of increasing water demand. [1]
Breaks down consumption by sector, allowing identification of agriculture as the dominant user, which is crucial for targeting sustainability strategies. [1]
Shows projected data to 2025, helping to anticipate future challenges. [1]

Limitations of Resource 1A:

Does not show spatial variation in water availability or stress; global totals mask regional differences. [1]
Does not indicate whether water withdrawal is sustainable (i.e., whether it exceeds renewable supply). [1]

Usefulness of Resource 1B:

Provides spatial information on where water stress is most severe, enabling geographical targeting of interventions. [1]
Classifies regions by stress level, allowing comparison and prioritisation. [1]

Limitations of Resource 1B:

Is a static snapshot for 2020; does not show temporal trends or future projections. [1]
Does not explain the causes of water stress or show consumption patterns by sector. [1]

Overall evaluation: Together, the resources are useful as Resource 1A shows the demand-side trends while Resource 1B shows the supply-side constraints. However, they do not show the relationship between withdrawal and availability, nor do they address governance, technology, or policy responses. A more complete understanding would require additional data on renewable water resources per capita and water management strategies.

Marking notes: Award up to 8 marks. Must include both usefulness and limitations for each resource, and an overall evaluative judgment. Level descriptors:

Level 3 (7–8 marks): Balanced evaluation of both resources with explicit judgment on overall usefulness.
Level 2 (4–6 marks): Some evaluation with strengths and limitations identified but limited overall judgment.
Level 1 (1–3 marks): Descriptive comments on resource content with little evaluation.

Question 2: Energy Resources and Sustainability (22 marks)

(a) Using Resource 2A, construct a suitable graph to show the changing energy mix of Country X between 2000 and 2020. [4]

Answer: A suitable graph would be a stacked bar chart or paired bar chart showing the percentage contribution of each energy source for 2000 and 2020.

Marking notes:

Appropriate graph type selected (stacked bar or paired bar): [1]
Axes correctly labelled with units (%): [1]
Data accurately plotted for both years: [1]
Clear legend/key identifying each energy source: [1]

(b) Describe the changes in Country X's energy mix between 2000 and 2020 as shown in Resource 2A. [4]

Answer:

Coal consumption decreased significantly from 45% to 30% of the energy mix. [1]
Oil consumption also decreased, from 35% to 28%. [1]
Natural gas increased from 12% to 18%. [1]
Renewables (solar, wind, hydro) showed the largest relative increase, from 3% to 16%. Nuclear also increased slightly from 5% to 8%. [1]

Marking notes: Award 1 mark for each valid change with supporting data. Accept observations about the overall shift from fossil fuels to cleaner sources.

(c) With reference to Resource 2B, explain two challenges that Country X faces in transitioning to renewable energy. [6]

Answer: Challenge 1: Intermittency and energy storage (3 marks)

Solar and wind power are intermittent sources; they do not generate electricity consistently (e.g., solar only during daylight, wind dependent on weather). [1]
This requires substantial investment in energy storage infrastructure (e.g., batteries, pumped hydro) to ensure reliable supply when generation is low. [1]
The cost and technological maturity of large-scale storage remain barriers to full renewable integration. [1]

Challenge 2: Grid infrastructure and land-use conflicts (3 marks)

The existing electricity grid was designed for centralised fossil fuel power plants; it requires upgrading to accommodate distributed renewable generation from multiple small-scale sources. [1]
Grid upgrades are expensive and time-consuming, potentially slowing the transition. [1]
Land-use conflicts arise from large-scale solar farms competing with agricultural land, creating tension between energy and food production goals. [1]

Marking notes: Award up to 3 marks per challenge. Must include explanation with reference to Resource 2B. Accept other valid challenges mentioned in the resource.

(d) "Technology is the key to achieving energy sustainability." Discuss this statement with reference to Resources 2A and 2B and your own knowledge. [8]

Answer: Arguments supporting the statement:

Resource 2A shows that technological development in renewables has enabled a significant increase from 3% to 16% of the energy mix, demonstrating technology's role in diversifying energy sources. [1]
Resource 2B mentions feed-in tariffs and subsidies that support renewable technology adoption, showing that policy can accelerate technological deployment. [1]
Technological advances in energy storage, smart grids, and energy efficiency are essential for managing intermittency and reducing overall demand. [1]
Examples: Advances in solar panel efficiency have reduced costs by over 80% since 2010; battery technology (e.g., Tesla Megapack) enables grid-scale storage. [1]

Arguments against/qualifying the statement:

Resource 2B highlights that technology alone is insufficient; grid infrastructure, land-use planning, and investment are also required. [1]
Political will and international cooperation are necessary to implement technology at scale (e.g., Paris Agreement commitments). [1]
Behavioural change (reducing energy consumption, adopting public transport) is equally important and cannot be achieved through technology alone. [1]
Economic barriers: developing countries may lack the capital to invest in renewable technology without international support. [1]

Overall judgment: Technology is a necessary but not sufficient condition for energy sustainability. It must be accompanied by supportive policies, behavioural change, and international cooperation to be effective.

Marking notes: Award up to 8 marks. Must present a balanced discussion with reference to resources and own knowledge. Level descriptors:

Level 3 (7–8 marks): Balanced discussion with explicit evaluation and supporting examples.
Level 2 (4–6 marks): Some balance with examples but limited evaluation.
Level 1 (1–3 marks): One-sided argument or descriptive with few examples.

Question 3: Food Resources and Sustainability (16 marks)

(a) Describe the spatial distribution of severe food insecurity as shown in Resource 3A. [4]

Answer:

Severe food insecurity is concentrated in Sub-Saharan Africa, including countries such as Ethiopia, Somalia, and South Sudan. [1]
Parts of the Middle East, specifically Yemen, also experience severe food insecurity. [1]
Afghanistan in South Asia is classified as severely food insecure. [1]
Haiti in the Caribbean is the only country in the Americas shown with severe food insecurity. [1]

Marking notes: Award 1 mark for each valid spatial observation with specific location reference. Accept use of continental/regional language.

(b) Explain two factors that contribute to severe food insecurity in the regions shown in Resource 3A. [6]

Answer: Factor 1: Conflict and political instability (3 marks)

Many severely food-insecure countries are affected by ongoing conflict (e.g., Yemen civil war, South Sudan conflict, Afghanistan instability). [1]
Conflict disrupts agricultural production by displacing farmers, destroying infrastructure, and blocking food distribution routes. [1]
Conflict also diverts government resources away from agricultural development and food security programmes towards military expenditure. [1]

Factor 2: Climate variability and environmental degradation (3 marks)

Sub-Saharan Africa and parts of the Middle East are highly vulnerable to drought and desertification due to their arid and semi-arid climates. [1]
Climate change is increasing the frequency and severity of droughts, reducing crop yields and livestock productivity. [1]
Environmental degradation, including soil erosion and deforestation, reduces the long-term productive capacity of agricultural land. [1]

Marking notes: Award up to 3 marks per factor. Accept other valid factors such as poverty, rapid population growth, poor infrastructure, or global food price volatility. Must include explanation with reference to specific regions.

(c) With reference to Resource 3B, explain how urban farming can contribute to food sustainability in cities. [6]

Answer:

Urban farming reduces reliance on food imports by producing food locally within the city, as shown by SkyGreens supplying local supermarkets. This shortens supply chains and improves food security. [2]
It reduces food miles and associated carbon emissions, as food does not need to be transported long distances from rural areas or overseas. This contributes to environmental sustainability. [2]
Urban farming creates green spaces and can improve urban liveability, as shown by the rooftop gardens in the photograph. The closed-loop water recycling system also demonstrates resource efficiency. [2]

Marking notes: Award up to 2 marks per explained contribution. Must reference Resource 3B. Accept other valid points such as providing fresher produce, creating employment, or educating urban residents about food production.

(d) Evaluate the usefulness of Resources 3A and 3B in helping to understand the global challenge of food sustainability. [6]

Answer: Resource 3A usefulness:

Provides a clear spatial overview of where food insecurity is most severe, enabling geographical prioritisation of interventions. [1]
Shows the global scale of the problem, highlighting that food insecurity is concentrated in specific regions. [1]

Resource 3A limitations:

Does not explain the causes of food insecurity or show temporal trends. [1]

Resource 3B usefulness:

Provides a concrete example of a technological solution (vertical farming) that addresses food sustainability challenges in urban contexts. [1]
Includes quantitative data (800 kg/day) and qualitative description of sustainability benefits. [1]

Resource 3B limitations:

Represents only one solution in one city (Singapore); may not be applicable to all contexts, particularly in developing countries with different resource constraints. [1]

Overall evaluation: Together, the resources are moderately useful. Resource 3A identifies the problem (where food insecurity exists), while Resource 3B offers one potential solution (urban farming). However, they do not address the full complexity of global food sustainability, including issues of food waste, dietary change, trade policies, and the scalability of urban farming in severely food-insecure regions.

Marking notes: Award up to 6 marks. Must include evaluation of both resources with an overall judgment. Level descriptors:

Level 3 (5–6 marks): Balanced evaluation with explicit judgment.
Level 2 (3–4 marks): Some evaluation with strengths and limitations.
Level 1 (1–2 marks): Descriptive with little evaluation.

Section B: Essay Questions (40 marks)

Question 4: Slums and Sustainable Urban Development (40 marks)

"Slums are the greatest impediment confronting cities in achieving sustainable urban development." How far do you agree with this statement? Support your answer with reference to specific examples.

Indicative Content:

Introduction (4 marks):

Define key terms: slums (informal settlements characterised by inadequate housing, lack of basic services, insecure tenure), sustainable urban development (development that meets present needs without compromising future generations, balancing economic, social, and environmental dimensions).
Acknowledge the complexity of the statement and outline the structure of the essay.
Indicate the stance: largely agree, partially agree, or largely disagree, with justification.

Arguments supporting the statement (12 marks):

Environmental challenges: Slums often lack proper sanitation and waste management, leading to water pollution and environmental degradation. Example: In Mumbai's Dharavi, untreated waste enters waterways, affecting downstream ecosystems.
Social challenges: Overcrowding, inadequate housing, and lack of access to healthcare and education perpetuate poverty and inequality. Example: Kibera in Nairobi has high rates of disease due to poor sanitation and limited healthcare access.
Economic challenges: Informal economies in slums operate outside regulatory frameworks, limiting tax revenue for city governments to invest in infrastructure and services. High crime rates in some slums deter investment.
Planning challenges: Slums often develop on hazardous land (floodplains, steep slopes) and in unplanned patterns, making infrastructure provision difficult and expensive. Example: Favela development on steep hillsides in Rio de Janeiro increases landslide risk.

Arguments against/qualifying the statement (12 marks):

Slums as solutions: Slums provide affordable housing for low-income workers essential to urban economies. Without slums, many cities would face even greater housing crises. Example: Dharavi's residents provide labour for Mumbai's formal economy.
Other impediments: Other factors may be greater impediments, such as car-dependent urban sprawl (environmental), gentrification and displacement (social), or corruption and poor governance (economic/political).
Slum upgrading successes: Examples of successful slum upgrading demonstrate that slums are not inherently incompatible with sustainability. Example: Favela Bairro programme in Rio de Janeiro provided infrastructure, land tenure, and services, improving living conditions without displacement.
Agency and resilience: Slum communities often demonstrate strong social networks, entrepreneurship, and adaptive capacity that can contribute to urban sustainability if supported.

Case study depth (8 marks):

Detailed knowledge of at least two specific examples (e.g., Dharavi/Mumbai, Kibera/Nairobi, favelas/Rio de Janeiro, Makoko/Lagos).
Specific details: population, area, conditions, interventions, outcomes.
Comparative analysis across examples.

Conclusion (4 marks):

Balanced judgment on the extent of agreement.
Acknowledge that slums present significant challenges but are symptomatic of broader failures in urban planning, housing policy, and economic inequality.
Suggest that addressing slums requires integrated approaches that recognise the role of informal settlements in urban systems.

Marking Scheme (40 marks):

Level	Marks	Descriptor
4	33–40	Excellent knowledge and understanding. Clear, balanced evaluation with well-supported arguments. Detailed and accurate case study evidence. Coherent structure and fluent expression.
3	25–32	Good knowledge and understanding. Some evaluation with supported arguments. Relevant case study evidence with some detail. Clear structure and competent expression.
2	17–24	Adequate knowledge and understanding. Limited evaluation; may be descriptive or one-sided. Some case study reference but lacking detail. Adequate structure.
1	9–16	Basic knowledge and understanding. Largely descriptive with little evaluation. Vague or absent case study evidence. Weak structure.
0	0–8	Very limited knowledge. Irrelevant or no case study evidence. Poor structure and expression.

Question 5: Climate Change Mitigation and Collective Action (40 marks)

"Climate change can only be mitigated with the collective effort of nations." To what extent do you agree with this statement? Support your answer with reference to specific examples.

Indicative Content:

Introduction (4 marks):

Define key terms: climate change mitigation (reducing greenhouse gas emissions or enhancing carbon sinks), collective effort (coordinated action by multiple nations through international agreements and cooperation).
Acknowledge the global nature of climate change as a "tragedy of the commons" problem.
Outline the structure and indicate stance.

Arguments supporting the statement (12 marks):

Global nature of the problem: Greenhouse gas emissions from any country affect the global atmosphere; unilateral action by one country cannot solve the problem alone.
Paris Agreement: The 2015 Paris Agreement demonstrates the necessity of collective action, with 196 parties committing to nationally determined contributions (NDCs). Example: The agreement's goal of limiting warming to well below 2°C requires coordinated global effort.
Carbon leakage: Without collective action, emissions-intensive industries may relocate to countries with weaker regulations, undermining mitigation efforts.
Technology transfer and finance: Developing countries require financial and technological support from developed nations to adopt low-carbon development pathways. Example: The Green Climate Fund channels resources from developed to developing countries.

Arguments against/qualifying the statement (12 marks):

National and sub-national action: Individual nations, states, and cities can take significant mitigation action independently. Example: Costa Rica generates over 98% of its electricity from renewable sources through national policy.
Non-state actors: Corporations, NGOs, and individuals play crucial roles. Example: Corporate renewable energy commitments (Google, Apple achieving 100% renewable energy) and divestment movements.
Technological innovation: Breakthroughs in renewable energy, energy storage, and carbon capture can be driven by individual countries or private sector research, not requiring collective agreement.
Limitations of collective action: International agreements can be slow, non-binding, and subject to political change (e.g., US withdrawal from and re-entry to Paris Agreement). Free-rider problems persist.

Case study depth (8 marks):

Detailed knowledge of international agreements (Paris Agreement, Kyoto Protocol) including specific commitments, mechanisms, and outcomes.
National examples: Costa Rica (renewable energy), Germany (Energiewende), China (world's largest renewable energy investor), Singapore (carbon tax).
Corporate/technological examples: renewable energy cost reductions, electric vehicle adoption.

Conclusion (4 marks):

Balanced judgment: collective effort is essential for addressing the global scale of climate change, but it must be complemented by national policies, private sector innovation, and individual action.
The effectiveness of collective action depends on the strength of commitments, enforcement mechanisms, and political will.

Marking Scheme (40 marks): Same level descriptors as Question 4.

Question 6: Alternative Energy and Climate Change Response (40 marks)

"Alternative energy sources hold the key for an effective response to climate change." Evaluate the validity of this statement with reference to specific examples.

Indicative Content:

Introduction (4 marks):

Define key terms: alternative energy sources (non-fossil fuel energy, primarily renewables such as solar, wind, hydro, geothermal, and nuclear), effective response to climate change (successfully reducing greenhouse gas emissions to limit global warming).
Acknowledge that energy production is the largest source of global greenhouse gas emissions.
Outline the structure and indicate stance.

Arguments supporting the statement (12 marks):

Decarbonising energy supply: Alternative energy sources produce little to no greenhouse gas emissions during operation, directly addressing the primary cause of climate change. Example: Denmark generates over 50% of its electricity from wind power, significantly reducing its carbon footprint.
Technological maturity and cost reduction: Solar and wind energy costs have fallen dramatically, making them economically competitive with fossil fuels. Example: Solar PV costs have fallen by over 80% since 2010, driving rapid adoption globally.
Energy security co-benefits: Alternative energy reduces dependence on fossil fuel imports, providing additional motivation for adoption. Example: Germany's Energiewende aims to transition to renewables for both climate and energy security reasons.
Scalability: Renewable energy potential is vast; solar energy alone could theoretically meet global energy demand many times over.

Arguments against/qualifying the statement (12 marks):

Intermittency and storage: Solar and wind are variable; reliable low-carbon electricity requires energy storage or backup generation, which adds cost and complexity.
Not a complete solution: Energy is not the only source of emissions; agriculture, deforestation, industrial processes, and transport also contribute significantly. Alternative energy alone cannot address these.
Implementation barriers: Political opposition, fossil fuel subsidies, grid infrastructure limitations, and land-use conflicts slow the transition. Example: NIMBYism (Not In My Backyard) opposition to wind farms in the UK.
Other essential responses: Energy efficiency, behavioural change (reducing consumption, shifting diets), afforestation, and carbon capture are also necessary components of an effective response.

Case study depth (8 marks):

Detailed examples of alternative energy adoption: Denmark (wind), Costa Rica (hydro and geothermal), China (solar and wind investment), Singapore (solar and regional power grids).
Examples of limitations: Germany's continued reliance on coal despite renewable growth; challenges of rare earth mineral supply for renewable technologies.
Examples of complementary approaches: energy efficiency standards, carbon pricing, reforestation programmes.

Conclusion (4 marks):

Balanced judgment: alternative energy is a crucial and necessary component of climate change response, but it is not sufficient alone. An effective response requires a portfolio of approaches including energy efficiency, behavioural change, and addressing non-energy emissions.
The "key" metaphor suggests primacy; while alternative energy is arguably the most important single element, it must be part of an integrated strategy.

Marking Scheme (40 marks): Same level descriptors as Question 4.
