Urban issues and challenges

Why cities grow, the opportunities and problems of LIC/NEE megacities and UK urban change, and what sustainable urban living looks like.

UNDERSTAND→RETRIEVE→REMEMBER
THE MEMORY HOOK
Cities grow faster than services — unless planning catches up.

The important bits

What you need to know

  1. 1

    Urbanisation is the rising share of people living in towns and cities. HICs urbanised during industrialisation; many LICs/NEEs are urbanising faster now through rural–urban migration and natural increase.

  2. 2

    Pull factors: jobs, education, healthcare, lights-and-wages stories. Push factors: farm fragmentation, mechanisation, drought, conflict. Megacities (10 million+) concentrate both opportunity and strain.

  3. 3

    AQA-style NEE case (often Rio or Mumbai): favelas/informal settlements with insecure tenure, but also strong informal economies, cultural energy, and self-help improvement (Favela Bairro-type schemes). Do not write only misery.

  4. 4

    Opportunities in an NEE city: industrial and service jobs, ports, universities, cultural industries. Challenges: squatter housing, water and sewage gaps, waste, air pollution, congestion, crime, inequality between zones.

  5. 5

    UK urban change: deindustrialisation, comparison shopping and online retail, migration, and regeneration. A named UK city (Bristol, Birmingham, Manchester, London) needs social, economic and environmental strands.

  6. 6

    Urban inequalities in the UK show up in life expectancy, education and housing within a few kilometres (a London borough contrast, or inner vs suburban Bristol). Regeneration can gentrify: new jobs, higher rents, displacement.

  7. 7

    Traffic, waste and air quality are the everyday environmental challenges. Solutions include integrated transport, congestion charges, brownfield first, urban greening, and waste hierarchies (reduce, reuse, recycle).

  8. 8

    Sustainable urban living is Freiburg-level detail if you have it: tram networks, eco-houses, social housing mix, parks, recycling. UK examples include Olympic Park legacy, BedZED, or a local park-and-ride. Sustainability means social and economic as well as green roofs.

Favelas are not just a problem to bulldoze

Informal settlements house a large share of many NEE cities because formal housing markets and planning cannot match migration. In Rio, favelas such as Rocinha sit on steep slopes with landslide risk, irregular water, and complicated relations with police and gangs. They also contain shops, churches, NGOs and political life. Site-and-service or upgrading schemes (paving, lighting, land titles, cable cars in some hills) often work better than clearance, which just shifts poverty. For exams, pair a challenge (cholera risk, crime statistics if taught) with an opportunity (cheap labour for the city, cultural industries, community policing pilots). One-sided favela paragraphs read as stereotype, not geography.

Regeneration’s double edge in UK cities

When docks, mills or mines close, cities try to replace them with services, universities, tourism and new flats. Bristol’s Harbourside or Manchester’s former industrial core can look like textbook success: jobs, cafes, listed buildings reused. The geographical question is distribution. If professional in-movers bid up rents, the original community may be pushed to the edge with longer commutes. Green claims can hide luxury glass. A 9-mark “evaluate regeneration” should use a named quarter, cite a social indicator, and decide how far the scheme met its stated aims rather than applauding cranes. Brownfield regeneration is still usually greener than eating the green belt — another weighing point.

WORKED EXAMPLE

See the idea in action

Question: using a named LIC/NEE city, explain how urban growth creates opportunities and challenges. City: Rio. Opportunity: oil, port and service jobs; Christ the Redeemer tourism; improvements such as pacification and cable cars in some favelas. Challenge: Rocinha’s density, water access, waste on slopes, inequality with Barra da Tijuca. Finish: growth created wealth and a dual city; management tries to connect them and has not finished the job.

Exam technique

Turn knowledge into marks

Learn one NEE city and one UK city in three columns: social, economic, environmental. Most urban questions are those three words in a trench coat.

Common mistakes

Do not give these marks away

  1. 01

    Writing about “Africa” or “poor cities” with no named place.

  2. 02

    Describing only problems in LIC/NEE cities and only success in the UK.

  3. 03

    Calling any park or recycling bin “sustainable” without explaining energy, equity or long-term cost.

QUICK RETRIEVAL

What are the two main causes of urbanisation in many LIC/NEE cities today?

ASuburbanisation and counter-urbanisation

BRural–urban migration and natural increase

CGlacial retreat and coastal erosion

DCongestion charging and green belts

Show the answer

Rural–urban migration and natural increase. People move for work and services, and young urban populations have more births than deaths. HIC urbanisation was earlier; some HIC cities now see counter-urbanisation as well.

Quick questions

If this is the bit you searched

What is a megacity?

A city with more than 10 million people. Many of the fastest-growing are in NEEs. Size brings agglomeration economies and brutal pressure on housing, water and transport.

Is brownfield always better than greenfield?

Usually for protecting countryside and reusing infrastructure, but brownfield can be contaminated and expensive. A fair answer weighs cost, wildlife on abandoned sites, and housing need.
