Answer Key and Marking Scheme
Paper: Practice Paper 1 – Themes in Geography Version: 4 of 5 Total Marks: 100
Section A: Climate Change and Flooding (50 marks)
Question 1 (4 marks)
Describe the temporal trends in global mean temperature anomaly and atmospheric CO₂ concentration shown in Resources 1A and 1B.
| Mark | Descriptor |
|---|---|
| 1 | Identifies that global mean temperature anomaly has increased over time, from 0.00°C (1850–1900 baseline) to +0.80°C (2001–2020). |
| 1 | Notes that the rate of warming has accelerated, with the largest increase occurring in the most recent period (1981–2020). |
| 1 | Identifies that atmospheric CO₂ concentration has risen steadily from 317 ppm (1960) to 414 ppm (2020). |
| 1 | Notes the consistent upward trend in CO₂ with no periods of decline, and/or quantifies the increase (e.g., an increase of 97 ppm over 60 years). |
Award 4 marks for a response that describes both spatial/temporal trends with specific data references.
Sample answer: Global mean temperature anomaly has increased from the 1850–1900 baseline to +0.80°C in the 2001–2020 period. The rate of warming has accelerated, with the most significant increase occurring after 1980. Atmospheric CO₂ concentration at Mauna Loa has risen consistently from 317 ppm in 1960 to 414 ppm in 2020, representing an increase of 97 ppm over 60 years, with no periods of decline.
Question 2 (6 marks)
With reference to Resources 1A and 1B, explain the relationship between atmospheric CO₂ concentration and global temperature change.
| Mark | Descriptor |
|---|---|
| 1–2 | Identifies a positive correlation between CO₂ concentration and temperature anomaly (both increase over time). |
| 3–4 | Explains the greenhouse effect mechanism: CO₂ traps outgoing longwave radiation, leading to atmospheric warming. References specific data to support the link (e.g., CO₂ rise from 317 to 414 ppm corresponds with temperature anomaly increase from +0.25°C to +0.80°C). |
| 5–6 | Provides a developed explanation linking the accelerated warming post-1980 to the rapid CO₂ increase in the same period. May note the time lag or cumulative effect of greenhouse gas emissions. Uses precise data from both resources to demonstrate the relationship. |
Award up to 6 marks for a well-developed explanation with specific resource evidence.
Sample answer: Resources 1A and 1B show a strong positive relationship between atmospheric CO₂ concentration and global temperature anomaly. As CO₂ increased from 317 ppm in 1960 to 414 ppm in 2020, the temperature anomaly rose from +0.25°C (1951–1980) to +0.80°C (2001–2020). This relationship is explained by the greenhouse effect: CO₂ molecules in the atmosphere absorb and re-emit outgoing longwave radiation from the Earth's surface, trapping heat and warming the lower atmosphere. The accelerated warming observed after 1980 (from +0.25°C to +0.80°C) corresponds with the period of most rapid CO₂ increase (from 339 ppm in 1980 to 414 ppm in 2020), suggesting that higher concentrations of greenhouse gases intensify the warming effect.
Question 3 (5 marks)
Explain the characteristics of the coastal community shown in Resource 1C, and suggest how these characteristics reflect the impacts of climate change on low-lying island states.
| Mark | Descriptor |
|---|---|
| 1 | Identifies one characteristic from the photograph (e.g., houses on stilts, sandbag walls, leaning coconut palms with exposed roots, sea encroachment). |
| 2 | Identifies a second characteristic with brief explanation. |
| 3 | Links one characteristic to a climate change impact (e.g., houses on stilts reflect adaptation to sea-level rise and coastal flooding). |
| 4 | Links a second characteristic to a climate change impact (e.g., sandbags and coral rubble walls indicate attempts at coastal protection against erosion). |
| 5 | Provides a developed explanation connecting multiple characteristics to the vulnerability of low-lying island states, demonstrating understanding of climate change impacts (sea-level rise, coastal erosion, saltwater intrusion, increased storm surges). |
Award 5 marks for a response that explains characteristics and links them clearly to climate change impacts.
Sample answer: Resource 1C shows several characteristics that reflect climate change impacts on Kiribati. The houses built on stilts indicate adaptation to rising sea levels and frequent coastal flooding, as elevated structures reduce flood damage during high tides. The sandbags and coral rubble walls along the beach represent attempts at coastal protection against erosion, which is exacerbated by sea-level rise and more intense storm surges associated with climate change. The leaning coconut palms with exposed roots suggest coastal erosion has undermined the soil, causing trees to destabilise—a common impact of shoreline retreat in low-lying atolls. The sea encroaching close to dwellings during high tide demonstrates the immediate threat of sea-level rise to habitable land. These characteristics collectively illustrate the high vulnerability of low-lying island states like Kiribati, where limited elevation and small land area leave communities with few options for retreat from climate change impacts.
Question 4 (6 marks)
With reference to Resources 2A and 2B, explain the development of Tropical Cyclone Idai in the Mozambique Channel in March 2019.
| Mark | Descriptor |
|---|---|
| 1–2 | Identifies key conditions for cyclone development from the resources: high sea surface temperatures (SST) of 28.8–30.2°C in the Mozambique Channel (Resource 2B), which exceed the 26.5°C threshold for cyclone formation. |
| 3–4 | Explains the mechanism: warm ocean water provides energy through evaporation; rising warm, moist air creates low pressure; the Coriolis force at approximately 16–19°S initiates rotation. References the SST anomaly of +1.2 to +1.8°C, indicating warmer-than-average conditions that provided additional energy. |
| 5–6 | Provides a developed explanation linking the specific conditions to Idai's intensification. Notes the rapid deepening of central pressure from 995 hPa to 915 hPa (Resource 2A) as evidence of intensification. Explains how the anomalously warm SSTs contributed to the cyclone reaching Category 4 intensity with wind speeds of 195 km/h. |
Award up to 6 marks for a well-developed explanation with specific resource evidence.
Sample answer: Tropical Cyclone Idai developed in the Mozambique Channel in March 2019 due to favourable atmospheric and oceanic conditions. Resource 2B shows sea surface temperatures of 28.8–30.2°C across the Channel, well above the 26.5°C threshold required for cyclone formation. These warm waters provided the energy source: high rates of evaporation transferred heat and moisture to the atmosphere, causing air to rise and creating an area of low pressure. The SST anomalies of +1.2 to +1.8°C above the 1981–2010 average indicate that the ocean was significantly warmer than normal, supplying additional energy for cyclone intensification. At latitudes of 16–19°S (Resource 2A), the Coriolis force was sufficient to initiate the rotation of the developing storm system. Resource 2A shows Idai's rapid intensification: central pressure dropped from 995 hPa on 9 March to 915 hPa by 14 March, while wind speeds increased from 65 km/h to 195 km/h, indicating the cyclone drew enormous energy from the anomalously warm Mozambique Channel waters.
Question 5 (5 marks)
Explain two impacts caused by the floods due to Tropical Cyclone Idai, as shown in Resource 2C.
| Mark | Descriptor |
|---|---|
| 1 | Identifies one impact from Resource 2C (e.g., 90% of Beira submerged, over 600 deaths, 1.5 million affected, cholera outbreak). |
| 2 | Explains the first impact with reference to the flood event (e.g., widespread inundation due to river flooding from Pungwe and Buzi rivers). |
| 3 | Identifies a second impact from Resource 2C. |
| 4 | Explains the second impact with reference to the flood event. |
| 5 | Provides developed explanations for both impacts, linking them to the characteristics of the flood event and the vulnerability of the affected population. |
Award 5 marks for two well-explained impacts with specific reference to Resource 2C.
Sample answer: One major impact of the floods was the widespread loss of life and displacement. Resource 2C states that over 600 people died in Mozambique and more than 1.5 million were affected across the region. The catastrophic flooding submerged 90% of Beira, a city of 530,000 people, leaving residents trapped in floodwaters and destroying homes. The scale of displacement reflects the intensity of the cyclone and the low-lying topography of the city, which amplified flood extent.
A second impact was the outbreak of waterborne diseases following the floods. Resource 2C notes that cholera cases surged in the weeks after the floods due to contaminated water supplies and damaged sanitation infrastructure. Floodwaters mixed with sewage and waste, contaminating drinking water sources. The destruction of sanitation facilities meant that even after floodwaters receded, residents lacked access to clean water and proper sanitation, creating conditions for cholera transmission. This secondary health impact demonstrates how flood disasters can have prolonged effects beyond the immediate inundation.
Question 6 (8 marks)
Evaluate the usefulness of Resources 2B and 2C in helping to understand the vulnerability of coastal cities to tropical cyclone hazards.
| Mark | Descriptor |
|---|---|
| 1–2 | Provides a basic evaluation, identifying what each resource shows. May describe content without assessing usefulness. |
| 3–4 | Identifies strengths of one or both resources (e.g., Resource 2B shows the physical hazard conditions; Resource 2C shows the human impacts). Begins to evaluate usefulness. |
| 5–6 | Evaluates both resources, identifying strengths and limitations of each. Resource 2B: useful for understanding hazard intensity (SST anomalies indicate cyclone energy) but limited as it does not show vulnerability factors. Resource 2C: useful for understanding consequences and vulnerability (population exposure, infrastructure weakness) but limited as it focuses on one event. |
| 7–8 | Provides a balanced, developed evaluation. Compares the resources, noting that together they provide complementary information (hazard + vulnerability = risk). Identifies specific limitations (temporal specificity, lack of comparative data, absence of long-term recovery information). Concludes with a clear judgment on overall usefulness. |
Award up to 8 marks for a well-balanced evaluation with specific reference to both resources.
Sample answer: Resource 2B is useful for understanding the physical hazard component of vulnerability. The SST data and anomalies show that the Mozambique Channel was significantly warmer than average in March 2019, providing the energy that enabled Cyclone Idai to intensify to Category 4 strength. This helps explain why coastal cities like Beira face such intense tropical cyclone hazards—warming ocean temperatures due to climate change may increase cyclone intensity. However, Resource 2B is limited because it only addresses the hazard side of vulnerability; it does not provide information about the city's exposure, sensitivity, or adaptive capacity.
Resource 2C is useful for understanding the consequences of tropical cyclone hazards and the underlying vulnerability of coastal cities. The text reveals that 90% of Beira was submerged, indicating high exposure due to low-lying topography and inadequate flood defences. The cholera outbreak demonstrates how damaged infrastructure and poor sanitation increase sensitivity to health impacts after floods. However, Resource 2C is limited to a single event and does not provide comparative data on how other cities have fared or what long-term recovery looks like.
Together, Resources 2B and 2C provide complementary information: Resource 2B explains why the hazard was so intense, while Resource 2C reveals the human and infrastructural vulnerabilities that turned the hazard into a disaster. Overall, the resources are useful for understanding the interaction of physical hazards and social vulnerability in coastal cities, though they would be strengthened by additional data on pre-existing socioeconomic conditions and long-term recovery outcomes.
Question 7 (16 marks)
'Climate change can only be mitigated with the collective effort of nations.' To what extent do you agree with this statement?
Marking Descriptors:
| Level | Marks | Descriptor |
|---|---|---|
| L1 | 1–4 | Descriptive response. May list examples of international cooperation or individual actions without evaluation. Limited or no reference to specific examples. |
| L2 | 5–8 | Explains the role of collective international effort in climate change mitigation. Some reference to examples (e.g., Paris Agreement). Begins to consider other actors but lacks balance or depth. |
| L3 | 9–12 | Provides a balanced discussion evaluating the role of collective international effort alongside other actors (national governments, corporations, individuals). Uses specific examples to support arguments. Shows understanding of barriers to collective action. |
| L4 | 13–16 | Sophisticated evaluation that weighs the necessity of collective action against the contributions of other actors. Demonstrates nuanced understanding of the interplay between international, national, and local scales of mitigation. Uses detailed, specific examples. Reaches a clear, justified conclusion. |
Indicative Content:
Arguments supporting collective effort:
- Climate change is a global commons problem requiring coordinated action (free-rider problem)
- Paris Agreement (2015) as a framework for collective action: 196 parties, nationally determined contributions (NDCs)
- IPCC assessments provide scientific consensus enabling collective policy responses
- Carbon markets and emissions trading require international cooperation (e.g., EU Emissions Trading System)
- Technology transfer and climate finance from developed to developing nations (e.g., Green Climate Fund)
- Examples: COP conferences, Montreal Protocol precedent for successful collective environmental action
Arguments qualifying or challenging the statement:
- National and sub-national policies can achieve significant emissions reductions independently (e.g., Costa Rica's renewable energy grid, California's vehicle emissions standards)
- Corporations and private sector initiatives drive innovation and emissions reductions (e.g., corporate net-zero commitments, renewable energy procurement)
- Individual behavioural change and community initiatives contribute to mitigation (e.g., dietary shifts, reduced consumption, local renewable energy projects)
- Some nations have demonstrated that unilateral action is possible and effective
- Collective action faces significant barriers: political will, economic costs, equity concerns between developed and developing nations
- The Paris Agreement's voluntary NDC mechanism has been criticised for lacking enforcement and insufficient ambition
Conclusion should:
- Weigh the evidence and reach a clear judgment on the extent of agreement
- Acknowledge that collective effort is necessary but not sufficient alone
- Recognise the multi-scalar nature of effective climate change mitigation
Award up to 16 marks based on the level descriptors above.
Section B: Urban Change (50 marks)
Question 8 (5 marks)
Explain the characteristics of the informal settlement shown in Resource 3B.
| Mark | Descriptor |
|---|---|
| 1 | Identifies one characteristic from the photograph (e.g., stilt houses over water, dense housing, use of canoes for transport, visible waste in water). |
| 2 | Identifies a second characteristic with brief explanation. |
| 3 | Explains one characteristic with reference to the context of informal settlements (e.g., stilt houses reflect adaptation to lack of available land and the lagoon environment). |
| 4 | Explains a second characteristic with reference to the context of informal settlements (e.g., dense housing indicates high population density and lack of formal planning). |
| 5 | Provides developed explanations linking multiple characteristics to the nature of informal settlements, demonstrating understanding of why such characteristics emerge (e.g., lack of formal infrastructure, poverty, rapid urbanisation). |
Award 5 marks for a response that explains characteristics with clear links to informal settlement contexts.
Sample answer: Resource 3B shows Makoko, an informal settlement in Lagos, with several distinctive characteristics. The wooden stilt houses built over the lagoon reflect adaptation to the lack of available land in the city; residents have constructed dwellings over water because formal land is unaffordable or unavailable. This is a common feature of informal settlements where residents use marginal land unwanted by formal developers. The dense clustering of housing with corrugated iron roofing indicates high population density and the use of cheap, available building materials, typical of self-built settlements where residents lack access to formal housing finance. The use of canoes for transport between dwellings shows the absence of formal road infrastructure, requiring residents to adapt their mobility to the aquatic environment. Visible waste floating in the water suggests a lack of formal waste collection services, a characteristic service deficit in informal settlements. The presence of a small market operating from canoes demonstrates the informal economy that develops in such settlements, providing livelihoods absent from the formal sector.
Question 9 (5 marks)
Account for the differences in access to basic services between formal and informal settlements in Lagos, as shown in Resource 3C.
| Mark | Descriptor |
|---|---|
| 1 | Identifies the key differences in service access (e.g., 78% vs. 12% for piped water, 92% vs. 35% for electricity). |
| 2 | Provides one reason for the disparity (e.g., informal settlements are often unrecognised by authorities, so utility companies do not extend infrastructure). |
| 3 | Provides a second reason for the disparity (e.g., residents of informal settlements often cannot afford connection fees or regular bills). |
| 4 | Develops one explanation with specific reference to the data (e.g., the 66 percentage point gap in piped water access reflects both physical and institutional barriers). |
| 5 | Provides developed explanations for the disparities, linking to the nature of informal settlements (lack of legal tenure, political marginalisation, poverty, difficult physical terrain for infrastructure). |
Award 5 marks for a well-explained account with specific reference to Resource 3C.
Sample answer: Resource 3C shows stark disparities in access to basic services between formal and informal settlements in Lagos. For piped water, only 12% of informal settlement residents have access compared to 78% in formal areas—a gap of 66 percentage points. This disparity can be accounted for by several factors. Firstly, informal settlements often lack legal recognition from authorities; because residents do not have formal land tenure, utility companies are reluctant or unable to extend piped water infrastructure to these areas. Secondly, the physical terrain of settlements like Makoko, built on water, makes laying pipes technically challenging and expensive. Thirdly, residents of informal settlements typically have lower and less stable incomes, making it difficult to afford connection fees or regular water bills even if infrastructure were available. For electricity, the 57 percentage point gap (92% vs. 35%) reflects similar barriers: informal connections may be dangerous and unofficial, while formal grid extension requires legal tenure and investment that utility companies are unwilling to make in unrecognised settlements. The waste collection disparity (80% vs. 10%) is particularly severe because narrow, unplanned pathways in informal settlements prevent access by collection vehicles, and local government services often do not extend to these areas.
Question 10 (6 marks)
With reference to Resources 3A and 3C, explain how rapid urban population growth contributes to challenges in service provision in cities such as Lagos.
| Mark | Descriptor |
|---|---|
| 1–2 | Identifies the rapid population growth in Lagos (from 7.2 million in 2000 to 14.4 million in 2020, 3.5% annual growth) and notes that this creates pressure on services. |
| 3–4 | Explains the mechanism: rapid growth outpaces infrastructure development; municipal authorities struggle to extend services to new residents; informal settlements expand faster than formal service provision. References the service access disparities in Resource 3C as evidence. |
| 5–6 | Provides a developed explanation linking population growth rates to specific service deficits. May discuss how the 3.5% annual growth rate means Lagos must provide services for approximately 250,000 additional residents each year, overwhelming planning and investment capacity. Connects the growth of informal settlements (where service access is lowest) to the inability of the formal housing market and service infrastructure to keep pace. |
Award up to 6 marks for a well-developed explanation with specific resource evidence.
Sample answer: Resource 3A shows that Lagos experienced rapid population growth from 7.2 million in 2000 to 14.4 million in 2020, doubling in just 20 years at an annual growth rate of 3.5%. This rapid growth contributes directly to challenges in service provision. At 3.5% annual growth, Lagos adds approximately 250,000–300,000 new residents each year, all of whom require water, sanitation, electricity, and waste collection services. Municipal authorities and utility companies struggle to extend infrastructure at a pace matching this demand, resulting in service deficits.
Resource 3C reveals the consequences: while formal settlements have relatively high service access (78–92%), informal settlements—which absorb much of the population growth—have severely limited access (10–35%). The rapid influx of rural migrants and natural population increase means that the formal housing market cannot supply sufficient affordable housing, pushing new residents into informal settlements where service provision is minimal. The 3.5% growth rate means infrastructure investment is perpetually playing catch-up; even where new water pipes or electricity grids are installed, population growth quickly creates new demand that outstrips supply. This cycle of growth outpacing provision explains why, despite economic development, service access disparities persist and may even widen in rapidly growing cities like Lagos.
Question 11 (4 marks)
State the hypothesis or research question that the students are investigating, and explain why Toa Payoh is a suitable location for this investigation.
| Mark | Descriptor |
|---|---|
| 1 | States a clear hypothesis or research question related to liveability for elderly residents (e.g., "Neighbourhood upgrading under the HDB Neighbourhood Renewal Programme improves liveability for elderly residents in Toa Payoh" or "How does neighbourhood upgrading affect liveability for elderly residents in Toa Payoh?"). |
| 2 | Explains one reason why Toa Payoh is suitable (e.g., high proportion of elderly residents at 22% vs. 15% national average). |
| 3 | Explains a second reason (e.g., presence of both older and upgraded precincts allows for comparison). |
| 4 | Provides a developed explanation linking the site characteristics to the investigation aims, demonstrating understanding of site selection principles in geographical fieldwork. |
Award 4 marks for a clear hypothesis and well-explained site suitability.
Sample answer: The students are investigating the hypothesis: "Elderly residents in the upgraded precinct (Site Y) perceive higher levels of liveability compared to those in the older precinct (Site X) in Toa Payoh." Toa Payoh is a suitable location for this investigation for several reasons. Firstly, the neighbourhood has a high proportion of elderly residents at 22% of the population, significantly above the national average of 15%, providing a large target population for data collection. Secondly, Toa Payoh contains both older precincts built in the 1960s (Site X) and upgraded precincts under the Neighbourhood Renewal Programme (Site Y), allowing for a comparative study of how upgrading affects liveability. This within-neighbourhood comparison controls for other variables such as location and access to amenities, strengthening the investigation design.
Question 12 (5 marks)
Explain how the students could minimise the impact of their investigation differently at Site X and Site Y.

| 1 | Identifies one way to minimise impact applicable to both sites (e.g., obtaining informed consent, conducting surveys at convenient times). |
| 2 | Explains a specific strategy for Site X (e.g., at the older precinct with narrow walkways, students should avoid obstructing pathways during pedestrian counts). |
| 3 | Explains a specific strategy for Site Y (e.g., at the upgraded precinct with senior activity centres, students should coordinate with centre staff to avoid disrupting activities). |
| 4 | Provides developed explanations for both sites, demonstrating understanding of how site characteristics necessitate different approaches. |
| 5 | Provides a comprehensive explanation covering ethical considerations, physical impact, and social disruption, with clear differentiation between the two sites. |
Award 5 marks for well-differentiated strategies with clear justification.
Sample answer: At Site X (the older precinct with walk-up apartments and narrow walkways), the students should take particular care to avoid obstructing pedestrian movement. The narrow walkways mean that even small groups of students conducting pedestrian counts or approaching residents for surveys could block passage, which would be especially problematic for elderly residents with mobility difficulties. Students should position themselves in wider areas or conduct observations from locations that do not impede foot traffic. They should also be sensitive to the fact that residents in this precinct may feel self-conscious about their living conditions; questions about liveability should be framed respectfully to avoid implying criticism of residents' homes.
At Site Y (the upgraded precinct), the students should coordinate with staff at the senior activity centres before conducting surveys or interviews. These centres provide important services and social spaces for elderly residents, and unsolicited approaches by students could disrupt activities or make residents uncomfortable. Students should seek permission from centre management, explain their research purpose clearly, and arrange to approach residents at appropriate times (e.g., after activities rather than during them). At both sites, students must obtain informed consent, ensure anonymity, and be mindful that elderly residents may need more time to respond to questions or may have hearing or vision difficulties requiring accommodation.
Question 13 (9 marks)
Evaluate the usefulness of the proposed data collection methods shown in Resource 4B for understanding liveability for elderly residents in Toa Payoh.
| Mark | Descriptor |
|---|---|
| 1–3 | Describes the methods without evaluation. May list what each method does. Limited or no assessment of usefulness. |
| 4–6 | Evaluates some methods, identifying strengths and/or limitations. Begins to assess how well the methods address the research aim. May treat methods in isolation rather than as a combined approach. |
| 7–9 | Provides a balanced evaluation of the combined methods. Identifies how different methods complement each other (e.g., quantitative surveys provide breadth, qualitative interviews provide depth). Discusses specific limitations (sample size, representativeness, potential bias). Reaches a clear judgment on overall usefulness for understanding elderly liveability. |
Indicative Content:
Strengths:
- Land-use survey provides objective data on physical infrastructure and accessibility features
- Pedestrian count quantifies actual usage patterns, indicating which facilities are valued
- Questionnaire survey (50 per site) provides quantifiable data on perceptions; allows comparison between sites
- Semi-structured interviews provide in-depth qualitative understanding of specific concerns
- Mixed methods approach (quantitative + qualitative) provides comprehensive understanding
- Methods are appropriate for the research aim and target population
Limitations:
- Sample size of 50 questionnaires per site may not be representative of the entire elderly population
- Pedestrian counts do not reveal purpose of movement or satisfaction levels
- Interviews with only 10 residents per site may capture limited perspectives
- Elderly residents may have difficulties with written questionnaires (literacy, vision)
- Presence of students may influence responses (Hawthorne effect)
- Methods capture perceptions at one point in time; liveability may vary seasonally
Conclusion should:
- Weigh strengths against limitations
- Assess whether the combination of methods provides sufficient evidence to answer the research question
- Suggest how usefulness could be improved (if appropriate)

Question 14 (16 marks)
'Slums are the greatest impediment confronting cities in achieving sustainable urban development.' How far do you agree with this statement?
Marking Descriptors:
| Level | Marks | Descriptor |
|---|---|---|
| L1 | 1–4 | Descriptive response. May describe slum conditions or list other urban challenges without evaluation. Limited or no reference to specific examples. |
| L2 | 5–8 | Explains how slums impede sustainable urban development. Some reference to examples. Begins to consider other impediments but lacks balance or depth. |
| L3 | 9–12 | Provides a balanced discussion evaluating slums as an impediment alongside other challenges (e.g., congestion, pollution, inequality, resource consumption). Uses specific case study examples. Shows understanding of the complexity of slums (both problems and functions). |
| L4 | 13–16 | Sophisticated evaluation that weighs the role of slums against other impediments to sustainable urban development. Demonstrates nuanced understanding of slums as both symptom and cause of unsustainable development. Uses detailed, specific examples from multiple cities. Reaches a clear, justified conclusion on the extent of agreement. |
Indicative Content:
Arguments supporting the statement:
- Slums concentrate multiple dimensions of unsustainability: environmental (lack of sanitation, pollution), social (poverty, inequality, health risks), economic (informal employment, low productivity)
- Service deficits in slums (water, sanitation, waste management) create environmental hazards affecting wider urban areas
- High population density in slums combined with poor infrastructure increases vulnerability to disasters (floods, disease outbreaks)
- Slums represent failure of urban planning and housing policy, undermining the social pillar of sustainability
- Examples: Dharavi (Mumbai) sanitation challenges, Kibera (Nairobi) lack of services, Makoko (Lagos) environmental degradation
Arguments qualifying or challenging the statement:
- Slums provide essential functions: affordable housing for low-income workers, entry points for rural-urban migrants, informal economic opportunities
- Other impediments may be equally or more significant: unsustainable resource consumption in wealthy urban areas, carbon emissions from transport and buildings, industrial pollution, urban sprawl
- Slums are a symptom of deeper structural problems: inadequate housing policy, inequality, rapid urbanisation without planning
- Some slum upgrading programmes have demonstrated that slums can be transformed rather than eliminated (e.g., Favela-Bairro in Rio de Janeiro, community-led upgrading in Mukuru, Nairobi)
- The greatest impediment may be governance failures and lack of political will rather than slums themselves
- Wealthy urban consumption patterns may have greater environmental impact than slum conditions
Conclusion should:
- Weigh the evidence and reach a clear judgment on the extent of agreement
- Acknowledge that slums present significant challenges but are not necessarily the "greatest" impediment
- Recognise that slums are interconnected with broader urban sustainability challenges
- Consider whether the framing of slums as an "impediment" overlooks the agency and resilience of slum communities
