ANSWER KEY AND MARKING SCHEME

Paper: Practice Paper 2 (Version 2 of 5) Total Marks: 100

SECTION A: Climate Change and Flooding (50 marks)

Question 1: Tropical Cyclone Distribution and Development

(a) Describe the spatial distribution of tropical cyclones as shown in Resource 1. [4 marks]

Answer/Marking Guide:

Award 1 mark for each valid spatial description with evidence from Resource 1:

Concentration in the Western North Pacific: The Western North Pacific basin recorded the highest number of tropical cyclones (610 cyclones, 1980–2020), accounting for the largest share of global cyclone activity.
Northern Hemisphere dominance: The three Northern Hemisphere basins (Western North Pacific, Eastern North Pacific, North Atlantic) together account for 1,230 cyclones, significantly more than the Southern Hemisphere basins (South Indian Ocean and South Pacific, 430 cyclones combined).
Limited activity in the North Indian Ocean: The North Indian Ocean basin recorded the fewest cyclones (110), representing the lowest frequency among all basins.
Latitudinal pattern: Cyclone activity is concentrated in tropical and subtropical latitudes, with no cyclone formation near the equator due to insufficient Coriolis force.

Mark allocation: 1 mark per valid point with specific reference to Resource 1 data (maximum 4 marks).

(b) With reference to Resources 1 and 2, explain the atmospheric and oceanic conditions necessary for the development of tropical cyclones. [6 marks]

Answer/Marking Guide:

Award marks for explaining conditions with reference to resources:

Sea surface temperature (SST) ≥26.5°C: Resource 2 shows SST of 28–30°C in the Mozambique Channel. Warm ocean water provides the energy source for cyclone development through high rates of evaporation, which releases latent heat as water vapour condenses, fuelling the cyclone's convection. [2 marks]
Low pressure system and atmospheric instability: The warm, moist air rises rapidly, creating a zone of low pressure at the surface. This draws in surrounding air, which is deflected by the Coriolis force, initiating rotation. Resource 1 shows cyclone formation occurs at latitudes where Coriolis force is sufficient (away from the equator). [2 marks]
Low vertical wind shear: For cyclone development to proceed, wind speed and direction must be relatively uniform with height. Strong wind shear would disrupt the vertical structure of the developing cyclone. The concentration of cyclones in certain basins (Resource 1) partly reflects regions with favourable wind shear conditions during cyclone seasons. [1 mark]
Pre-existing disturbance: Tropical cyclones typically develop from pre-existing weather disturbances (e.g., tropical waves). The high frequency in the Western North Pacific (Resource 1) reflects the frequent occurrence of such disturbances in this region. [1 mark]

Mark allocation: Up to 6 marks for well-explained conditions with clear reference to Resources 1 and 2. Award partial marks for identification without explanation.

Question 2: Climate Change Evidence and Impacts

(a) Using Resource 3, describe the trend in global average temperature anomalies from 1880 to 2020. [3 marks]

Answer/Marking Guide:

Overall warming trend: Global average temperature anomalies have increased from −0.2°C (1880–1900) to +0.8°C (2000–2020), indicating a clear long-term warming of approximately 1.0°C over the period. [1 mark]
Accelerating rate of warming: The rate of temperature increase has accelerated over time. The anomaly increased by 0.3°C between 1880–1900 and 1920–1940, by 0.1°C between 1920–1940 and 1960–1980, and by 0.6°C between 1960–1980 and 2000–2020. The most recent period shows the most rapid warming. [1 mark]
Correlation with CO₂: The temperature increase corresponds with rising CO₂ concentrations from 290 ppm to 400 ppm, suggesting a relationship between greenhouse gas emissions and global warming. [1 mark]

Mark allocation: 1 mark per valid trend description with reference to Resource 3 data (maximum 3 marks).

(b) Explain two impacts of climate change on coastal communities, with reference to Resource 4 and your own knowledge. [6 marks]

Answer/Marking Guide:

Award up to 3 marks for each well-explained impact:

Impact 1: Coastal erosion and land loss [3 marks]

Rising sea levels, caused by thermal expansion of oceans and melting of land-based ice, lead to increased coastal erosion.
Resource 4 describes coastal erosion affecting small island developing states (SIDS) in the Pacific.
This results in loss of land for housing, agriculture, and infrastructure, threatening livelihoods and forcing relocation.
Example: In Tuvalu and Kiribati, coastal erosion has led to the loss of habitable land and plans for population relocation.

Impact 2: Saltwater intrusion [3 marks]

Sea level rise causes saltwater to intrude into freshwater aquifers and agricultural land.
Resource 4 mentions saltwater intrusion affecting SIDS communities.
This contaminates drinking water supplies and reduces agricultural productivity, threatening food and water security.
Example: In Bangladesh, saltwater intrusion in coastal areas has affected rice cultivation and forced farmers to switch to salt-tolerant crops or abandon agriculture.

Alternative acceptable impact: Displacement of communities [3 marks]

Loss of habitable land and resources forces coastal communities to relocate.
Resource 4 references displacement of communities in Pacific SIDS.
This creates climate refugees, placing pressure on receiving areas and causing social and economic disruption.

Mark allocation: 3 marks per impact (1 mark for identification, 2 marks for explanation with example/evidence). Maximum 6 marks.

Question 3: Flooding and Hydrological Processes

(a) Compare the shape of the storm hydrograph before and after urbanisation as shown in Resource 5. [4 marks]

Answer/Marking Guide:

Award 1 mark for each valid comparison:

Peak discharge: Post-urbanisation peak discharge (28 m³/s at 4 hours) is significantly higher than pre-urbanisation peak discharge (12 m³/s at 4 hours). The post-urbanisation peak is more than double the pre-urbanisation peak. [1 mark]
Rising limb steepness: The rising limb is steeper after urbanisation, with discharge increasing from 5 to 28 m³/s in 4 hours (post-urbanisation) compared to 5 to 12 m³/s (pre-urbanisation), indicating faster runoff response. [1 mark]
Lag time: The lag time (time between peak rainfall and peak discharge) is shorter after urbanisation. Both hydrographs peak at 4 hours, but the post-urbanisation hydrograph shows a more rapid rise, suggesting reduced lag time. [1 mark]
Recession limb: The recession limb is steeper after urbanisation, with discharge falling from 28 to 8 m³/s between hours 4 and 10, compared to a more gradual decline from 12 to 5 m³/s pre-urbanisation. This indicates faster drainage after the peak. [1 mark]

Mark allocation: 1 mark per valid comparison with data reference (maximum 4 marks).

(b) Explain how urbanisation affects hydrological processes within a drainage basin, using evidence from Resource 5. [6 marks]

Answer/Marking Guide:

Award marks for explaining processes with reference to Resource 5:

Reduced infiltration and increased surface runoff: Urbanisation replaces permeable surfaces (soil, vegetation) with impermeable surfaces (concrete, asphalt, roofs). This reduces infiltration capacity, causing more rainfall to become surface runoff. Resource 5 shows this through the higher peak discharge (28 m³/s vs 12 m³/s) and steeper rising limb after urbanisation, indicating more water reaching the river quickly as surface runoff rather than infiltrating into the ground. [2 marks]
Reduced evapotranspiration and interception: Urbanisation removes vegetation, reducing interception of rainfall by leaves and reducing evapotranspiration. More rainfall reaches the ground directly, contributing to increased runoff. The higher discharge volumes in the post-urbanisation hydrograph (Resource 5) partly reflect this reduced water loss through evapotranspiration. [2 marks]
Faster drainage through artificial channels: Urban drainage systems (storm drains, canals, culverts) are designed to remove water quickly, reducing lag time and concentrating flow. Resource 5 shows the steeper recession limb after urbanisation, indicating faster drainage of water from the basin through engineered channels compared to natural drainage pathways. [2 marks]

Mark allocation: Up to 6 marks for well-explained processes with clear reference to Resource 5 evidence. Award partial marks for identification without explanation.

Question 4: Climate Change Mitigation and Adaptation

"'International cooperation is the only effective way to address the challenges of climate change.' Discuss the validity of this statement." [16 marks]

Marking Scheme and Response Framework:

Level Descriptors:

Level	Marks	Descriptor
L4	13–16	Excellent evaluation with balanced discussion of international cooperation and alternative approaches. Well-supported with specific examples and case studies. Clear, sustained argument with valid conclusion.
L3	9–12	Good discussion with some evaluation. Relevant examples provided but may lack depth or balance. Argument is clear but may not be fully sustained.
L2	5–8	Basic discussion with limited evaluation. Examples may be generic or limited. Argument is present but lacks development.
L1	1–4	Descriptive rather than evaluative. Limited or no examples. Weak argument structure.

Expected Content:

Arguments supporting international cooperation:

Global nature of climate change: Greenhouse gas emissions from any country affect the global atmosphere. Unilateral action by individual nations cannot address the problem if others continue to emit. International cooperation is necessary to achieve global emissions reductions.
Paris Agreement (2015): The first universal, legally binding global climate deal. 196 parties agreed to limit global warming to well below 2°C above pre-industrial levels. The agreement established a framework for nationally determined contributions (NDCs) and a mechanism for increasing ambition over time. However, current NDCs are insufficient to meet the 2°C target.
IPCC and scientific cooperation: The Intergovernmental Panel on Climate Change provides the scientific basis for understanding climate change and informing policy. International scientific cooperation is essential for monitoring, modelling, and understanding climate systems.
Technology transfer and finance: Developing countries require financial and technological support to transition to low-carbon development. International mechanisms such as the Green Climate Fund facilitate this transfer. Without international cooperation, developing countries may lack resources for mitigation and adaptation.
Carbon markets and trading: International carbon markets (e.g., EU Emissions Trading System, Clean Development Mechanism) allow cost-effective emissions reductions across borders. These require international agreement and cooperation to function effectively.

Arguments challenging the statement (alternative approaches):

National and sub-national action: Some nations and cities have implemented ambitious climate policies independently of international agreements. Examples: Costa Rica's renewable energy programme (generating over 98% of electricity from renewables), California's emissions standards, and the C40 Cities network.
Corporate and private sector initiatives: Many corporations have set net-zero targets and invested in renewable energy independently of government mandates. Examples: Google's carbon-neutral operations since 2007, Apple's commitment to 100% renewable energy, and the RE100 initiative.
Civil society and individual action: Grassroots movements, NGOs, and individual behavioural changes contribute to climate action. Examples: Fridays for Future movement, community renewable energy projects, and shifts towards plant-based diets.
Technological innovation: Advances in renewable energy, energy storage, and carbon capture technology can drive emissions reductions regardless of international cooperation. The rapid cost reduction in solar and wind energy has made them economically competitive with fossil fuels.
Limitations of international cooperation: International agreements face challenges including free-rider problems, lack of enforcement mechanisms, slow negotiation processes, and political changes (e.g., US withdrawal from and re-entry to the Paris Agreement). The effectiveness of international cooperation is limited by these factors.

Conclusion: A balanced conclusion should acknowledge that international cooperation is essential but not sufficient alone. Effective climate action requires a multi-scalar approach combining international agreements, national policies, corporate action, and individual behaviour change. The statement is partially valid but overstates the exclusivity of international cooperation.

Mark allocation: Award marks based on level descriptors. Expect 3–4 well-developed paragraphs with specific examples for top marks.

Question 5: Flood Management Strategies

(a) With reference to Resource 6, explain two structural flood management strategies used in Singapore. [5 marks]

Answer/Marking Guide:

Award up to 2.5 marks for each well-explained strategy:

Strategy 1: Stamford Detention Tank [2.5 marks]

This is an underground storage facility that temporarily holds excess stormwater during heavy rainfall events.
It reduces peak discharge in the Stamford Canal by storing water and releasing it gradually after the storm passes.
This prevents the canal from overflowing and flooding surrounding urban areas.
The strategy exemplifies structural flood management through engineered infrastructure that modifies the drainage system's capacity.

Strategy 2: Marina Barrage [2.5 marks]

Marina Barrage is a dam across the Marina Channel that serves multiple functions including flood control.
During heavy rain, crest gates are opened to release excess water from Marina Reservoir into the sea, preventing flooding in low-lying city areas.
It also acts as a tidal barrier, preventing high tides from pushing seawater into the drainage system.
This strategy demonstrates structural flood management through large-scale engineering works that control water levels.

Alternative acceptable strategy: ABC Waters Programme [2.5 marks]

While primarily a non-structural approach focusing on community engagement and water-sensitive urban design, elements such as bioretention swales and rain gardens are structural features that enhance infiltration and slow runoff.

Mark allocation: 2.5 marks per strategy (1 mark for identification, 1.5 marks for explanation with reference to Resource 6). Maximum 5 marks.

SECTION B: Urban Change (50 marks)

Question 6: Urban Liveability Investigation

(a) State a suitable hypothesis for this investigation. [2 marks]

Answer/Marking Guide:

Award 2 marks for a clear, testable hypothesis that relates to the investigation context. Award 1 mark for a partially correct or vague hypothesis.

Example acceptable hypotheses:

"Elderly residents in Toa Payoh perceive higher levels of urban liveability compared to elderly residents in Punggol." [2 marks]
"The availability of elderly-friendly facilities is greater in Toa Payoh than in Punggol." [2 marks]
"There is a significant difference in the satisfaction levels of elderly residents between Toa Payoh and Punggol." [2 marks]

Mark allocation: 2 marks for a clear, specific, and testable hypothesis. 1 mark for a hypothesis that is relevant but vague or not clearly testable.

(b) Explain two reasons why the students chose to compare Toa Payoh and Punggol for their investigation. [4 marks]

Answer/Marking Guide:

Award 2 marks for each well-explained reason:

Reason 1: Contrasting estate ages and development stages [2 marks]

Toa Payoh is one of Singapore's oldest housing estates (developed from the 1960s), while Punggol is a newer estate (developed from the 1990s–2000s).
Comparing estates of different ages allows the students to investigate whether older estates, which may have more established facilities and community networks, offer different liveability outcomes for elderly residents compared to newer estates with modern infrastructure.
This provides a basis for understanding how urban planning and estate age affect elderly liveability.

Reason 2: Different planning approaches and facilities [2 marks]

Toa Payoh was developed under earlier public housing models with different design philosophies, while Punggol was planned as a "Punggol 21" waterfront town with newer amenities.
Comparing these estates allows investigation of how different planning approaches affect elderly liveability, including accessibility, healthcare facilities, and social spaces.
This comparison can reveal whether newer planning approaches better address elderly needs.

Alternative acceptable reason: Accessibility of data and feasibility [2 marks]

Both estates are accessible from the students' junior college, making fieldwork feasible within time and resource constraints.
Both have significant elderly populations, providing sufficient sample sizes for surveys.

Mark allocation: 2 marks per reason (1 mark for identification, 1 mark for explanation). Maximum 4 marks.

(c) Evaluate the usefulness of surveys as a data collection method for this investigation. [6 marks]

Answer/Marking Guide:

Award marks for a balanced evaluation of strengths and limitations:

Strengths of surveys: [up to 3 marks]

Direct data on perceptions and experiences: Surveys allow collection of primary data on elderly residents' subjective experiences of liveability, including satisfaction with facilities, sense of safety, and social connections. This data cannot be obtained from secondary sources. [1 mark]
Quantifiable and comparable data: Survey responses can be quantified and statistically analysed, allowing systematic comparison between Toa Payoh and Punggol. The students can calculate average satisfaction scores and identify significant differences. [1 mark]
Reasonable sample size: With 50 respondents per neighbourhood (100 total), the survey provides a reasonable basis for identifying patterns and drawing conclusions about elderly liveability in each estate. [1 mark]

Limitations of surveys: [up to 3 marks]

Sampling bias: The survey sample may not be representative of all elderly residents. Those who are less mobile, socially isolated, or unwilling to participate may be excluded, skewing results towards more active and engaged residents. [1 mark]
Response bias and accuracy: Elderly respondents may provide socially desirable answers, may not accurately recall information, or may interpret questions differently. Language barriers or cognitive decline could affect response quality. [1 mark]
Limited depth: Surveys provide breadth but limited depth. They cannot capture the nuanced reasons behind satisfaction or dissatisfaction, which might be better explored through in-depth interviews or focus groups. [1 mark]

Overall evaluation: Surveys are useful for collecting standardised, comparable data on elderly liveability perceptions, but should be complemented with other methods (interviews, observations) for a more complete understanding. [1 mark for balanced conclusion]

Mark allocation: Up to 6 marks for balanced evaluation with specific reference to the investigation context. Award marks for both strengths and limitations.

Question 7: Slums and Sustainable Urban Development

(a) Explain the characteristics of informal settlements as seen in Resource 7. [5 marks]

Answer/Marking Guide:

Award 1 mark for each well-explained characteristic with reference to Resource 7:

High population density and overcrowding: Resource 7 shows densely packed multi-storey structures with minimal space between buildings. This indicates high population density, with many residents living in close proximity, leading to overcrowded living conditions. [1 mark]
Narrow, irregular alleyways: The photograph shows narrow passageways between buildings, characteristic of unplanned development. These alleyways provide limited access for emergency services and contribute to poor ventilation and lighting. [1 mark]
Informal construction and building materials: The structures in Resource 7 appear to be constructed from a mix of materials, suggesting incremental, self-built housing without formal building approval or adherence to building codes. This reflects the informal nature of settlement development. [1 mark]
Overhead utility connections: Resource 7 shows overhead electrical wires, indicating informal or semi-formal connections to utilities. This suggests limited formal infrastructure provision and potential safety hazards from unsafe electrical connections. [1 mark]
Limited open space and amenities: The photograph shows a lack of open space, parks, or recreational areas. This reflects the absence of formal urban planning and the prioritisation of housing over amenity provision in informal settlements. [1 mark]

Mark allocation: 1 mark per characteristic with explanation and reference to Resource 7 (maximum 5 marks).

(b) Account for the differences in service provision shown in Resource 8. [6 marks]

Answer/Marking Guide:

Award marks for explaining reasons for differences with reference to Resource 8 data:

Government policy and investment: Rocinha (Rio de Janeiro) shows the highest service provision (85% piped water, 75% sanitation, 95% electricity), reflecting Brazil's favela upgrading programmes such as Favela-Bairro, which invested in infrastructure and service provision in informal settlements. In contrast, Kibera (Nairobi) shows the lowest provision (20% water, 15% sanitation), reflecting limited government investment and recognition of informal settlements in Kenya. [2 marks]
Duration and stage of settlement development: Rocinha has existed since the 1940s and has undergone gradual upgrading over decades, allowing services to be extended over time. Dharavi (Mumbai) shows intermediate service levels (45% water, 35% sanitation), reflecting its long history but ongoing challenges in service provision. Kibera's lower provision partly reflects its more recent growth and limited upgrading. [2 marks]
Economic context and city resources: Rio de Janeiro, as part of Brazil's larger economy, has had greater resources for slum upgrading compared to Nairobi. Mumbai, despite being in a rapidly growing economy, faces challenges of scale with Dharavi's large population. The differences in service provision reflect the varying economic capacities and priorities of the respective city and national governments. [2 marks]

Mark allocation: Up to 6 marks for well-explained reasons with specific reference to Resource 8 data. Award partial marks for identification without explanation.

Question 8: Urban Sustainability Strategies

(a) With reference to Resource 9, explain how one of these strategies contributes to urban sustainability. [4 marks]

Answer/Marking Guide:

Award up to 4 marks for explaining one strategy's contribution to sustainability:

Option A: Curitiba's BRT System

Environmental sustainability: The BRT system has reduced car usage by 30%, leading to lower greenhouse gas emissions and improved air quality. By providing an efficient public transport alternative, it reduces reliance on private vehicles. [2 marks]
Social sustainability: Serving over 2 million passengers daily, the BRT system provides affordable and accessible transport for all residents, enhancing mobility and access to employment, education, and services. This promotes social equity. [1 mark]
Economic sustainability: The BRT system is more cost-effective than rail-based mass transit, making it financially sustainable for the city. Reduced congestion also improves economic productivity by reducing travel times. [1 mark]

Option B: Singapore's Park Connector Network

Environmental sustainability: The network links over 300 km of parks and nature reserves, preserving and connecting green spaces that support biodiversity, provide ecosystem services, and moderate urban temperatures (reducing urban heat island effect). [2 marks]
Social sustainability: The Park Connector Network promotes recreation and active lifestyles, improving physical and mental health. It provides accessible green space for all residents, enhancing quality of life and social interaction. [1 mark]
Economic sustainability: Green spaces increase property values and attract tourism. The network also encourages walking and cycling, reducing transport costs and healthcare expenditure through improved public health. [1 mark]

Mark allocation: Up to 4 marks for explaining contributions to sustainability with reference to Resource 9. Award marks for addressing environmental, social, and/or economic dimensions.

(b) Assess the success of strategies used to improve urban liveability in a city you have studied. [12 marks]

Marking Scheme and Response Framework:

Level Descriptors:

Level	Marks	Descriptor
L4	10–12	Excellent assessment with balanced evaluation of strategy success. Well-supported with specific examples from a named city. Clear criteria for assessing success. Sustained argument with valid conclusion.
L3	7–9	Good assessment with some evaluation. Relevant examples provided but may lack depth or balance. Success criteria are identified but not fully developed.
L2	4–6	Basic assessment with limited evaluation. Examples may be generic. Limited development of success criteria.
L1	1–3	Descriptive rather than evaluative. Limited or no specific examples. Weak argument structure.

Expected Content (example using Singapore):

Define urban liveability and success criteria:

Urban liveability encompasses factors including housing quality, accessibility, environmental quality, safety, and social infrastructure.
Success can be assessed by outcomes (improved quality of life indicators), sustainability (long-term viability), inclusivity (benefits across social groups), and unintended consequences.

Strategy 1: Public Housing (HDB) and Estate Renewal

Description: HDB provides housing for over 80% of Singapore's population. Estate renewal programmes (e.g., Home Improvement Programme, Neighbourhood Renewal Programme) upgrade older estates.
Success: High home ownership rates (over 90%), improved living conditions, and social mixing through ethnic integration policies.
Limitations: Rising costs, ageing population needs not fully addressed, some estates still require upgrading.

Strategy 2: Green Spaces and Park Connector Network

Description: Singapore's "City in a Garden" vision includes park connectors, nature reserves, and community gardens.
Success: High accessibility to green spaces, improved air quality, recreational opportunities, and biodiversity conservation.
Limitations: Pressure on green spaces from development, unequal distribution in some areas, maintenance costs.

Strategy 3: Public Transport (MRT, Buses)

Description: Extensive MRT network and bus system providing island-wide connectivity.
Success: High public transport mode share, reduced car dependency, improved accessibility.
Limitations: Overcrowding during peak hours, last-mile connectivity issues, ageing population accessibility challenges.

Conclusion: Overall, Singapore's strategies have been largely successful in improving urban liveability, as evidenced by high rankings in global liveability indices. However, challenges remain in addressing ageing population needs, maintaining affordability, and balancing development with environmental conservation.

Mark allocation: Award marks based on level descriptors. Expect 3–4 well-developed paragraphs with specific examples for top marks.

Question 9: Urbanisation and Development

(a) Using Resource 10, describe the trends in urban population growth in Africa and Asia between 1950 and 2020. [4 marks]

Answer/Marking Guide:

Award 1 mark for each valid trend description with data reference:

Rapid urban population growth in both regions: Africa's urban population increased from 33 million (1950) to 587 million (2020), an increase of over 17 times. Asia's urban population increased from 234 million to 2,340 million, a 10-fold increase. Both regions experienced substantial urban population growth. [1 mark]
Asia's larger absolute urban population: Asia's urban population (2,340 million in 2020) is approximately four times larger than Africa's (587 million), reflecting Asia's larger total population. However, both regions have seen dramatic increases. [1 mark]
Africa's faster relative growth: Africa's urban population grew by a factor of 17.8 (from 33 to 587 million), compared to Asia's factor of 10 (from 234 to 2,340 million). This indicates a faster rate of urban population growth in Africa, albeit from a smaller base. [1 mark]
Lower urbanisation rates despite large urban populations: Despite large urban populations, both Africa (43%) and Asia (51%) have lower urbanisation rates compared to Europe (75%), indicating that a significant proportion of their populations still reside in rural areas and further urbanisation is likely. [1 mark]

Mark allocation: 1 mark per valid trend with specific reference to Resource 10 data (maximum 4 marks).

(b) Explain two causes of rapid urbanisation in developing countries. [6 marks]

Answer/Marking Guide:

Award up to 3 marks for each well-explained cause:

Cause 1: Rural-to-urban migration [3 marks]

People move from rural areas to cities in search of better economic opportunities, employment, and higher wages.
Push factors in rural areas include agricultural mechanisation reducing labour demand, land scarcity, poverty, and limited access to services (education, healthcare).
Pull factors in urban areas include perceived job opportunities in manufacturing and services, better infrastructure, and higher living standards.
Example: In China, millions have migrated from rural areas to cities like Shanghai and Shenzhen for factory and service sector employment, driving rapid urbanisation.

Cause 2: Natural population increase in urban areas [3 marks]

Urban populations grow through natural increase (births exceeding deaths) as well as migration.
Urban areas typically have better healthcare, reducing mortality rates, while fertility rates may remain relatively high, especially among migrant populations.
Younger age structures in cities (due to migration of young adults) contribute to higher birth rates.
Example: In many African cities, natural increase accounts for a significant proportion of urban population growth alongside rural-to-urban migration.

Alternative acceptable cause: Reclassification of urban areas [3 marks]

As settlements grow and develop, they may be reclassified from rural to urban, contributing to measured urbanisation.
This reflects the spatial expansion of cities into surrounding rural areas and the development of new urban centres.

Mark allocation: 3 marks per cause (1 mark for identification, 2 marks for explanation with example). Maximum 6 marks.

Question 10: Urban Challenges and Responses

"'Slums are undesirable in cities but they do offer solutions to some urban challenges.' Do you agree with this statement? Support your answer with examples." [16 marks]

Marking Scheme and Response Framework:

Level Descriptors:

Level	Marks	Descriptor
L4	13–16	Excellent evaluation with balanced discussion of both the undesirable aspects and functional roles of slums. Well-supported with specific case study examples. Clear, sustained argument with valid conclusion.
L3	9–12	Good discussion with some evaluation. Relevant examples provided but may lack depth or balance. Argument is clear but may not be fully sustained.
L2	5–8	Basic discussion with limited evaluation. Examples may be generic or limited. Argument is present but lacks development.
L1	1–4	Descriptive rather than evaluative. Limited or no examples. Weak argument structure.

Expected Content:

Arguments supporting the undesirability of slums:

Inadequate housing and living conditions: Slums are characterised by overcrowding, poor-quality construction, and lack of basic services. Example: In Kibera, Nairobi, residents live in structures made of mud and corrugated iron, with extremely high population densities.
Health risks: Poor sanitation, lack of clean water, and overcrowding contribute to the spread of diseases. Example: In Dharavi, Mumbai, shared toilet facilities and inadequate waste management create health hazards, including during the COVID-19 pandemic.
Environmental degradation: Unplanned settlements often lack proper waste disposal and may be located in environmentally sensitive areas. Example: Informal settlements along rivers in Jakarta contribute to water pollution and are vulnerable to flooding.
Social problems: Slums may be associated with crime, insecurity of tenure, and social exclusion. Residents often lack formal property rights and face the constant threat of eviction.
Impediment to sustainable urban development: Slums challenge cities' ability to achieve environmental, social, and economic sustainability goals. They represent a failure of urban planning and housing policy.

Arguments supporting the functional role of slums:

Affordable housing provision: Slums provide low-cost housing that formal markets fail to supply. Example: Dharavi provides housing for an estimated 600,000 to 1 million people at costs far below formal housing in Mumbai, enabling low-income workers to live near employment centres.
Economic contributions: Slums are sites of significant economic activity, including small-scale manufacturing, recycling, and services. Example: Dharavi's informal economy generates an estimated US$1 billion annually through industries including leather, pottery, and recycling. Slum residents contribute to the broader urban economy as labour.
Social networks and community support: Slums often develop strong community networks that provide mutual support, security, and social capital. These networks help residents cope with poverty and access opportunities.
Pathway to urban integration: For many rural-to-urban migrants, slums serve as entry points to the city, providing a foothold from which residents can gradually improve their circumstances. Over time, some slums are upgraded and integrated into the formal city.
Entrepreneurship and innovation: The informal nature of slum economies fosters entrepreneurship and adaptation. Residents develop innovative solutions to challenges of space, resources, and services.

Conclusion: A balanced conclusion should acknowledge that while slums present significant challenges and are undesirable in many respects, they fulfil functions that formal urban systems have failed to provide. The statement is valid to a significant extent. The appropriate response is not slum clearance but upgrading and integration, recognising the role slums play while addressing their deficiencies. Examples such as favela upgrading in Rio de Janeiro (Favela-Bairro programme) and incremental improvements in Dharavi demonstrate approaches that work with rather than against existing communities.

Mark allocation: Award marks based on level descriptors. Expect 3–4 well-developed paragraphs with specific case study examples for top marks.
