Other contemporary urban environmental issues explained
Urban environments face severe ecological challenges, notably atmospheric pollution, water pollution, and dereliction, which manifest differently depending on a city's development level.
Read the full explanation
Atmospheric pollution, driven by vehicular emissions and industrial activity, causes respiratory diseases and smog. Water pollution arises from inadequate sanitation and industrial effluent contaminating urban watercourses. Dereliction involves abandoned industrial or residential zones, often linked to deindustrialisation. Students must examine these three issues across contrasting urban areas, such as the photochemical smog and slum sanitation crises in Mumbai compared to the legacy of brownfield dereliction and nitrogen dioxide traffic emissions in London.
Strategies to manage these environmental problems.
Urban environmental problems require targeted management. Cities can reduce atmospheric pollution through clean-air or low-emission zones, congestion charging, cleaner public transport, emission standards and land-use planning that lowers traffic exposure. Water-pollution strategies include separating or upgrading sewers, improving wastewater treatment, regulating industrial effluent, intercepting contaminated runoff and using sustainable drainage where it reduces polluted surface flows. Dereliction can be addressed through surveying and remediating contaminated brownfield land, reusing buildings, improving public space and using planning or financial incentives to attract suitable redevelopment. Each strategy should be evaluated for effectiveness, cost, equity, enforcement and possible displacement of pollution or deprivation.
Your focus
- Identify the primary causes of atmospheric pollution, water pollution, and dereliction in urban environments.
- Compare the manifestation and severity of these environmental problems between two contrasting cities.
- Evaluate the relationship between a city's level of economic development and its specific environmental challenges.
Show all 6 objectives
- Describe specific strategies used to manage urban atmospheric and water pollution.
- Explain methods used to remediate derelict land and return brownfield sites to safe use.
- Evaluate the effectiveness and trade-offs of urban environmental management strategies using named evidence.
Other contemporary urban environmental issues exam tips
Marking Points
- Analyse the causes and impacts of atmospheric pollution, such as particulate matter and nitrogen oxides from transport and industry.
- Explain the sources of urban water pollution, including untreated sewage, surface run-off, and industrial discharge.
- Examine the process of dereliction, linking it to economic restructuring, deindustrialisation, and urban decline.
- Compare how these three environmental problems vary in scale, cause, and management between two contrasting urban areas.
- Identify specific strategies used to manage atmospheric pollution, such as low-emission zones, emission controls, pedestrianisation or improved public transport.
- Explain how urban water pollution can be reduced through effluent regulation, sewer and treatment upgrades, runoff management and suitable drainage measures.
- Evaluate how brownfield remediation, building reuse and regeneration can reduce dereliction while considering cost, contamination and displacement.
- Assess named strategies using evidence of environmental outcomes alongside economic cost, enforcement and social equity.
Examiner Tips
- 💡Prepare specific, quantifiable evidence for each problem in both contrasting cities, such as air quality index scores or hectares of derelict land.
- 💡Link the environmental problems to their socio-economic impacts, such as the health costs of waterborne diseases or respiratory conditions.
- 💡Evaluate the effectiveness of management strategies used to tackle these issues in your chosen contrasting urban areas.
- 💡Use specific, named examples of cities when discussing management strategies to add depth and spatial context to your answers.
- 💡Categorise strategies into legislation, technological fixes, and behavioural changes to structure your evaluation effectively.
- 💡Consider the economic and social costs of environmental strategies, such as the financial burden of emission zones on low-income residents.
Common Mistakes
- Error: Focusing solely on one environmental issue while ignoring the others. Correction: Ensure balanced coverage of atmospheric pollution, water pollution, and dereliction as required by the specification.
- Error: Using contrasting cities but failing to explicitly compare their environmental problems. Correction: Directly contrast the issues, for example comparing water pollution from inadequate sewage infrastructure in a developing city with industrial chemical run-off in a developed city.
- Error: Confusing dereliction with general urban poverty. Correction: Define dereliction specifically as the abandonment and decay of buildings and land, often requiring brownfield remediation.
- Discussing environmental problems without detailing the specific management strategies; ensure the focus remains on the solutions and their implementation.
- Confusing global environmental strategies with local urban ones; focus on city-scale interventions like congestion charges rather than international climate treaties.
- Failing to evaluate the strategies; always consider the limitations, costs, or varying success rates of management schemes in different urban contexts.
