Notes for answers

• Decentralisation is the outward relocation of people and/ or businesses

from the city centre / CBD (1) (to the edges / suburbs / fringes of the

city)

• Business seeking to expand or redevelop their operations, relocate to

sites towards, or beyond the edge of the existing urban area (1).

Availability of large areas of more affordable land (1d) and improved

access to transport networks (1d) act as pull factors.

• Push factors such as high air pollution levels may have encouraged

people to move out of central areas (1).

• With improvements to wealth and socioeconomic development some

residents may become dissatisfied with outdated, poor quality and

crowded housing in some central areas (1). The availability of large

areas of more affordable land on the rural-urban fringe and beyond,

allows developers to build housing estates with larger more attractive

dwellings, acting as a pull factor for some more affluent residents to

more outwards from central urban areas (1d).

• Changes in lifestyle and retailing can lead to both shoppers and

retailers leaving traditional CBDs and town centres, in favour of

out-of-town shopping centres (1d). Large areas of cheaper land are

attractive for the developers and retailers (1d), whilst access to road

networks and space for large free car parks is attractive to shoppers

(1d).

• Responses may refer policy making and implementation at local

levels. For example, the elected mayors in a number of British

conurbations. This is credit worthy as long as the response focuses

on possible causes of this process.

• People working from home (WFH) no longer needing to be close to

city centre work places (1). – A-LEVEL GEOGRAPHY – –

AO3 – Analysis of the overall Global Power City Index score for the

selected cities between 2015 and 2022. Analysis of the components

of the GPCI scores for the selected cities in 2022.

Mark scheme

Level 2 (4–6 marks)

AO3 – Clear analysis of the quantitative evidence provided which makes

appropriate use of data to support. Clear connections between different

aspects of the data.

Level 1 (1–3 marks)

AO3 – Basic analysis of the quantitative evidence provided which makes

limited use of data to support. Basic or limited connections between

different aspects of the data.

Notes for answers

The question requires analysis of the data shown in Figure 5 and Figure

5b. Connections should be made between different aspects of the data.

AO3

• Figure 5a shows that there is some variation in the GPCI scores for

the selected cities between 2015 and 2022.

• Figure 5a shows that scores for most cities fluctuate across the period,

but all cities end on a higher score in 2022 than they started on in

2015. There is significant difference in the change in overall GPCI

scores between 2015 and 2022. Singapore has the smallest increase,

~30 points, whilst Shanghai’s increase is the largest, about 7 times

more than Singapore’s, gaining just under 200 points.

• Figure 5a shows that 90% (9) of the cities had their peak GPCI score

in 2018, with Shanghai being the anomaly peaking in 2022.

• Figure 5a shows that there is very limited change in the rank order of

the 5 highest scoring cities. Once Tokyo overtakes Paris after 2015,

the top 5 remain in the same order. London 1st, New York 2nd, Tokyo

3rd, Paris 4th and Singapore 5th. There is more swapping of ranks for

the bottom 5 cities. For example, Amsterdam is two places higher by

2022 than in 2015. Shanghai and Los Angeles swap places 3 times.

• Figure 5a shows that the range in overall GPCI score is slightly lower

in 2022 than in 2015. In 2015 the range is about 580 points and about

490 points in 2022, a decrease of about 90 points.

• Figure 5b shows that there is some variation in the proportions of each

component’s contribution to the overall GPCI scores of each city in

2022.

• Figure 5b shows that for 90% of the cities the factor that contributes

the largest element of their overall score in 2022 is ‘Liveability’. New

York is the anomaly where ‘Liveability’ is its 2–A-LEVEL GEOGRAPHYndlargest component,– –

and it is the only city where ‘Economy’ is its biggest component.

• Figure 5b shows that for 4/5 of the cities ‘Economy’ is the second

largest component of their overall score in 2022. This time London is

an anomaly with ‘Economy’ being its 3rd largest component.

• Figure 5b shows that for 80% of the cities the factor contributing the

least to their overall GPCI score in 2022 is ‘R&D’. Los Angeles is the

most significant anomaly, as ‘R&D’ is its 3rd highest element.

• Despite having the lowest overall GPCI score in 2022 in Figure 5a, Los

Angeles has the 3rd largest score for ‘R&D’, showing what an important

component ‘R&D’ is for Los Angeles.

• Figure 5a shows that London and New York, 1st and 2nd place

respectively, have overall GPCI scores significantly higher than the

cities in 3rd and 4th place. Analysis of Figure 5b suggests that it is

London’s score for ‘Cultural Interaction’ that makes it the dominant city

overall. Whilst New York’s ‘Economy’ score is the largest of all the

cities, the gap between London and New York’s ‘Cultural Interaction’

more than cancels this out. In this category London has a score of

about 340 against New York’s score of about 250, a difference of

about 90 points. Interestingly, Figure 5a shows that the difference

between London and New York’s overall score in 2022 is also about

90 points. – A-LEVEL GEOGRAPHY – –

Notes for answers

This question requires a discussion of the characteristics of fortress

developments. Candidates are required to apply their knowledge and

understanding to figures 6a and 6b but can also consider other urban

areas and cities. The focus of the question should be on–A-LEVEL GEOGRAPHYthe extent to– –

which the map and photograph sources depict the Royal Palm Yacht and

Country Club as a fortress development.

AO1

• New urban landscapes: fortress developments.

• Urban characteristics in contrasting settings. Physical and human

factors in urban forms. Spatial patterns of land use, economic

inequality, social segregation and cultural diversity in urban areas, and

the factors that influence them.

20 • Issues associated with economic inequality, social segregation and

cultural diversity in contrasting urban areas.

AO2

• Analysis of Figure 6a and Figure 6b may come to the view that the

map and photographs show that it is an enclosed/secure site.

Responses may assess that this does suggest that Royal Palm does

have characteristics of a fortress development.

• The isolated/gated nature of Royal Palm does match that of fortress

developments, where access to the place is prevented or strictly

controlled. Royal Palm has only 2 gated access points, and is

separated from other developments by water, nature reserves and the

main highway.

• The use of fences/boundaries in such developments acts as both a

physical barrier to those outside, but also implies that the area inside is

private, and that if you are not a resident then you are not allowed

inside. In this respect use of Figure 6a may come to the view that

Royal Palm does have the characteristics of a fortress development.

• Analysis of Figure 6a, may come to the view that the presence of its

own private golf course and yacht club, suggests that Royal Palm is an

exclusive community for wealthy residents, which may suggest that it

does have characteristics of a fortress development or gated

community.

• Analysis of Figure 6b may suggest that, like in Figure 6a, there is

clearly a concern for maintaining the security of those living in Royal

Palm. Assessment may come to the view that having controlled gated

access and security patrols to maintain the security of the place is a

characteristic of fortress developments.

• Analysis of Figure 6b may suggest that there is a fear or suspicion of

those who are not permitted to enter, or of those who do not belong in

Royal Palm. Responses may come to the view that such a concern

with excluding those from outside of the place is a characteristic of

fortress developments.

Notes for answers

This question requires students to assess the relative importance of

factors that contribute to a sustainable city. There is no requirement to

name specific sustainable cities, but it is highly likely that candidates will

support their assessment with illustrative examples. This is appropriate

and credit will be given to named examples where appropriate.

AO1

– A-LEVEL GEOGRAPHY – –

• Economic, social, technological, political and demographic processes

associated with urbanisation.

• Impact of urban areas on local and global environments. Ecological

22 footprint of major urban areas.

• Dimensions of sustainability: natural, physical, social and economic.

Nature and features of sustainable cities.

• Contemporary opportunities and challenges in developing more

sustainable cities.

• Strategies for developing more sustainable cities.

AO2

• Analysis of the concept of sustainable cities. The sustainability of

urban areas relates to the level of quality of life provided for its

residents, fair governance, and level of impact on the environment.

• Assessment comes to the view that a sustainable city is one that

provides a high standard of living, with good employment, a clean and

healthy environment, has fair governance and is inclusive for all.

• Assessment comes to the view that a sustainable city is one that has a

focus on environmental management and a low ecological footprint.

• Assessment of the importance of social development as a contributing

factor of a sustainable city. Responses may assess the importance of:

- Education and healthcare provision

- Availability and quality of food supplies

- Green housing and buildings

- Clean water and sanitation

- Green public transport

• Assessment of the importance of economic development as a

contributing factor of a sustainable city. Responses may assess the

importance of:

- Decent employment opportunities

- Production and distribution of renewable energy

- Investment in green technology and innovation

• Assessment of environmental management as a contributing factor of

a sustainable city. Response may assess the importance of:

- Waste and recycling management

- Energy efficiency

- Water management

- Air quality conservation

- Adaptation and mitigation of climate change

- Forest and soil management

• Assessment of urban governance as a contributing factor of a

sustainable city. Response may assess the importance of:

- Adoption of green urban planning and design strategies

- Strategies to reduce inequalities

- Strengthening of civil and political rights

- Support of local, national, regional and global links

AO1

• Changes in the carbon cycle over time, to include human impact

(including hydrocarbon fuel extraction and burning, farming practices,

deforestation, land use changes).

• The carbon budget and the impact of the carbon cycle upon land,

ocean and atmosphere, including global climate.

• Urban temperatures: the urban heat island effect. Precipitation:

How to answer it

AQA A-Level Geography: Contemporary Urban Environments Master Guide

WHAT THIS QUESTION TESTS

This paper tests core themes from Section B (Contemporary Urban Environments) and synoptic connections to Section A (Water and Carbon Cycles):

  • AO1 (Knowledge & Understanding): Causes of urban decentralisation, features of postmodern fortress landscapes, dimensions of urban sustainability, and the physical mechanisms linking atmospheric carbon to urban heat, drainage, and smog.
  • AO2 (Application & Evaluation): Deconstructing resource stimulus (Florida gated community), assessing the relative weighting of sustainability factors, and evaluating synoptically whether climate change makes urban environmental management increasingly difficult.
  • AO3 (Data & Skills): Critical comparative analysis of compound graphical indices (Global Power City Index scores and compositional breakdowns).
QUESTION 03.1 • 4 MARKS [AO1 = 4]

Causes of Urban Decentralisation

Outline causes of decentralisation in urban areas.

✅ Model Answer Structure

Award 1 mark per valid point plus an extra mark for supporting development (d):

  • Commercial/Retail Push & Pull: High land values, CBD congestion, and business rates push retailers out, while edge-of-town greenfield sites offer cheaper land, motorway junction accessibility, and free customer parking (d).
  • Residential/Socioeconomic Drivers: Urban pollution, crime, and sub-standard inner-city housing act as push factors, whilst affluence and desire for larger homes with gardens drive suburbanisation and counter-urbanisation (d).
  • Structural & Technological Shifts: Rapid broadband and flexible working models (WFH) mean employees and footloose service firms no longer need central city locations (d).

🧠 Exam Technique & Mark Scheme Rule

The "Rule of Two": The mark scheme states that to achieve the full 4 marks, more than one cause must be addressed.

If you write an exceptional, in-depth paragraph covering only retail decentralisation, you will be capped at a maximum of 3 marks.

Target Formula: 2 causes × 2 marks each (Point + Development) = 4/4 marks.

❌ Common Errors

  • Confusing decentralisation with deindustrialisation: Writing solely about factory closures in the 1970s without linking to the outward movement of people, retail, or service offices.
  • Vague assertions: Stating "people want to move away because cities are bad" without qualifying specific geographical mechanisms (e.g., negative externalities like air pollution vs. pull of green space).

💡 Key Term Definition

Decentralisation: The outward movement and relocation of people, employment, retail, and commercial activities from the central urban core/CBD to the suburbs, urban fringe, or surrounding rural-urban fringe settlements.

QUESTION 03.2 • 6 MARKS [AO3 = 6]

Analysing Global Power City Index (GPCI) Data

Analyse the data shown in Figure 5a and Figure 5b.

✅ What Top-Level Responses Synthesised

  • Overall Temporal Trend (5a): Scores fluctuate between 2015 and 2022, yet all cities finish higher in 2022 than 2015. However, growth rates vary vastly (Shanghai grew by nearly 200 points; Singapore grew by only ~30 points).
  • Turning Points (5a): ~90% of cities peaked in 2018 (Shanghai peaked anomaly in 2020). London consistently retained 1st rank, NY 2nd, Tokyo 3rd, Paris 4th, Singapore 5th; greater rank volatility occurred below 5th (Shanghai & LA swapped 3 times).
  • Breakdown Anomaly Analysis (5b): For 4 out of 5 cities, 'Economy' is the largest component in 2022. London is an anomaly where Economy ranks 3rd, but London dominates decisively in 'Cultural Interaction'.
  • Synthesising 5a & 5b: London's cultural lead over NY (~340 vs ~250) compensates for its lower economic score, explaining why London edges New York overall by ~90 points in Figure 5a.

🧠 Level 2 (4–6 marks) Descriptor Demands

To reach Level 2, you must provide "clear connections between different aspects of the data".

  • Do not describe Figure 5a and then Figure 5b in isolation!
  • Directly correlate the breakdown categories in 5b with the comparative overall scores and rank standings shown in 5a.
  • Quote precise manipulated data (e.g., differences, percentage shares, point changes) rather than merely reading numbers off axes.

❌ Common Examiner Criticisms

Students often spent half their time writing explanatory reasons for the changes (e.g., "London did well because of Brexit/multinationals").

Command Word Alert: The command is "Analyse", not "Explain". Explaining causes earns 0 marks under AO3 and wastes valuable time.

QUESTION 03.3 • 9 MARKS [AO1 = 4, AO2 = 5]

Postmodern Landscapes: Fortress Developments

Using Figure 6a, Figure 6b and your own knowledge, examine how this development fits the characteristics of fortress developments.

💡 Key Knowledge (AO1)

  • Fortress Landscape: Urban design that uses physical and technological security measures to defend spaces, control access, and polarise socioeconomic groups.
  • Common Features: Gated entrances, perimeter walls/fences, hostile architecture, private security guards, high-frequency CCTV, and privatisation of public space.
  • Theoretical Context: Driven by perceived/real fear of crime and rising social segregation in post-industrial or postmodern cities.

✅ Applying the Stimulus (AO2 Evidence)

  • Enclosed & Controlled Access (Fig 6a): Royal Palm has only two physical gated access points. It is surrounded on three sides by water bodies/nature reserves and a major highway, acting as modern "moats" and physical barriers.
  • Privatisation & Exclusivity (Fig 6a): Internal land use is dominated by an exclusive private yacht club and private golf course, physically segregating wealthy elites from the wider urban population.
  • Surveillance & Patrols (Fig 6b): Visual presence of uniform security staff in branded vehicles and physical barrier arms demonstrates militarised, 24/7 boundary monitoring to deter 'undesirables'.

🧠 Exam Technique: Reaching Level 3 (7–9 marks)

Level 3 requires an evaluation/examination, not just a descriptive checklist. Top candidates question the nuances:

  • While Royal Palm exemplifies the classic defensive, exclusionary American gated community, does it fit all fortress criteria? (e.g., hostile street architecture like anti-homeless spikes is typical of downtown fortress designs, whereas suburban Florida relies on physical perimeter isolation).
  • Conclude clearly on the degree to which it creates an artificial, socially polarised micro-environment.

❌ Common Errors

Treating Figure 6a/6b as mere background pictures and writing a generic essay on social polarisation without explicitly citing the security gates, patrol trucks, waterways, or gated access points from the insert.

QUESTION 03.4 • 9 MARKS [AO1 = 4, AO2 = 5]

Urban Sustainability: Relative Importance of Factors

Assess the relative importance of factors contributing to a sustainable city.

💡 Dimensions of Urban Sustainability (AO1)

  • Environmental: Renewable energy, circular waste management, water conservation, sustainable urban drainage systems (SUDS), green transport networks.
  • Economic: Decent employment opportunities, green technology innovation, local economic resilience, circular economy principles.
  • Social: Equal access to high-quality healthcare, education, affordable housing, safe public realms, recreation, and social cohesion.
  • Governance & Political: Transparent planning, community engagement, enforcement of green building codes, and strong civic institutions.

🧠 Assessing "Relative Importance" (AO2)

You cannot score in Level 3 without explicitly weighing the factors against each other:

  • Argument A (Governance as Foundation): Without robust political will, long-term funding, and master-planning (e.g., Curitiba or Freiburg), environmental infrastructure and social equity schemes cannot be implemented or enforced.
  • Argument B (Economic Viability): Cities must remain economically dynamic to finance costly green transitions (e.g., retrofitting buildings or mass transit).
  • Synthesis/Conclusion: True sustainability requires an interdependent balance; neglecting social equity while achieving environmental targets simply drives gentrification and displacement (eco-gentrification).

❌ Pitfalls to Avoid

  • The "Eco-Only" Trap: Writing exclusively about recycling, bike lanes, and solar panels, completely ignoring social, economic, and governance pillars.
  • Pure Description: Describing a case study (e.g., BedZED or Masdar City) from memory without returning to assess the relative importance of the contributing factors.
QUESTION 03.5 • 20 MARKS [AO1 = 10, AO2 = 10]

Synoptic Essay: Carbon Cycle Disruptions vs Urban Environmental Management

'Impacts of changes to the carbon cycle will make managing environmental problems in urban areas more difficult.' To what extent do you agree with this statement?

💡 The Synoptic Link: Connecting Carbon Cycle to Urban Microclimates & Systems

Changes in the carbon cycle (enhanced greenhouse effect driven by fossil fuel combustion and land-use change) cause global climate changes: rising sea levels, increased mean atmospheric temperatures, altered precipitation patterns, and more frequent/intense extreme storms. These global physical changes directly compound local urban environmental problems:

1. Thermal Issues:

Global warming exacerbates the local Urban Heat Island (UHI) effect, increasing night-time heat stress and intensifying photochemical smog formation (photolysis of NO₂ to produce ground-level O₃ accelerates at higher temperatures).

2. Hydrological Stress:

Convective storms and high-intensity rainfall events overwhelm traditional stormwater drains and SUDS, increasing pluvial flash flooding and sewer overflow discharge.

3. Coastal & River Inundation:

Rising sea levels and storm surges threaten coastal megacities, causing land loss, saltwater intrusion into aquifers, and structural damage that leads to dereliction.

✅ Arguments Agreeing with the Statement

  • Exceeding Engineering Capacity: Urban drainage infrastructure (gutters, sewers, retention ponds) was calibrated to historical return periods (e.g., 1-in-100 year events). Increased frequency of high-intensity precipitation overwhelms SUDS swales and retention basins, turning roads into channels.
  • Compounding Air Quality Crises: Higher ambient temperatures accelerate atmospheric chemical reaction kinetics, exacerbating photochemical smog and ground-level ozone formation, making particulate and smog reduction targets unattainable without radical bans.
  • Coastal Vulnerability & Retreat: In low-lying megacities (e.g., Jakarta, Miami), thermal expansion of oceans and ice-sheet melting cause chronic tidal flooding and aquifer contamination, making flood defence management economically unfeasible and prompting managed retreat or abandonment.

⚖️ Counter-Arguments & Alternative Factors

  • Non-Carbon Urban Problems: Many acute urban environmental problems are strictly local and unrelated to the global carbon cycle: industrial dereliction, domestic solid waste generation, toxic heavy metal landfill leachate, and noise pollution.
  • Adaptive Capacity & Technology: High-income cities possess technological and financial resilience. Innovation in cool roofs, reflective pavements, expanded wetland buffers, and smart water storage can mitigate warming and flood risks.
  • The Core Bottleneck is Governance/Finance, Not Climate: In rapidly expanding LIC/NEE cities (e.g., Lagos, Mumbai), the inability to manage flooding or smog stems primarily from rapid unplanned informal growth, inadequate taxation, and lack of municipal infrastructure, rather than climate change alone.

🧠 How to Secure Level 4 (16–20 marks)

  • Balanced, Nuanced Conclusion: Agree that carbon cycle changes act as a critical risk multiplier, dramatically increasing the cost and engineering complexity of water and temperature management. However, emphasize that the severity of the challenge is mediated by the city’s level of economic development and governance capacity.
  • Accurate Terminology: Integrate vocabulary from both units: radiative forcing, carbon budget, anthropogenic emissions, sensible heat flux, albedo, photochemical smog, SUDS, pluvial flooding, infiltration capacity.
  • Explicit Scale Contrasts: Compare the capacity of HIC cities (e.g., London's Thames Barrier upgrades, Tokyo's G-Cans underground discharge channel) against LIC/NEE informal settlements built on floodplains.

❌ Common Pitfalls in this 20-Marker

One-Sided Physical Geography Essay: Writing pages on the carbon cycle, greenhouse effect, and Milankovitch cycles without linking them to specific urban management strategies (e.g., ULEZ, SUDS, river restoration, cool roofs).
