Urban Futures: Cities Around the World

Ever wondered why some cities have over 10 million people whilst others struggle with massive slums? Urbanisation is happening at different speeds globally, with the fastest growth occurring in Africa and Asia where people are still moving from countryside to cities.

Megacities (over 10 million people) grow because of natural increase, migration for jobs, and economic development. Beyond megacities, we have world cities like London and New York $the only two alpha++ cities$ that serve as global trade hubs. The future might bring metacities - imagine Tokyo with over 37 million people!

The rapid growth creates serious problems, especially in poorer countries. When cities can't cope with rural-urban migration, slums develop where over 1 billion people worldwide now live. These settlements often lack clean water, electricity, and proper sanitation, making them dangerous places with risks of fire, disease, and building collapse.

Key Point: Rural-urban migration happens due to push factors (problems in countryside) and pull factors (opportunities in cities).

UK Urban Trends and Opportunities

British cities have gone through massive changes that directly affect where you might live and work in the future. Suburbanisation saw people move to the edges of cities for cheaper housing and less pollution. Then counter-urbanisation took people to the countryside entirely, leaving city centres neglected.

Since the 1980s, urban regeneration has transformed UK cities through re-urbanisation. This brings derelict areas back to life, creates new homes and jobs, and improves quality of life. Green belts around cities prevent sprawling development, though housing shortages make this policy controversial.

Cities offer brilliant opportunities: better education, healthcare, transport, longer life expectancy, more jobs, and greater sustainability. Everything you need is within easy reach, making cities incredibly efficient places to live.

However, urbanisation creates challenges too. Inequality means extreme wealth next to poverty, segregation keeps rich and poor apart, and overpopulation can exceed available jobs and housing. Environmental damage from unplanned development also threatens natural spaces.

Key Point: Urban regeneration since the 1980s has reversed decades of decline in UK city centres.

Birmingham: A Global City Case Study

Birmingham isn't just Britain's second-largest city - it's a truly global place that shows how migration shapes modern cities. With over 1.1 million people from around the world, it has one of the largest Pakistani communities globally and the biggest Irish community in England.

The city's global connections are impressive: 12,000 international students, fair-trade chocolate production using Ghanaian cocoa, the invention of balti curry, and Europe's largest working jewellery quarter. Migration waves from Asia and the West Indies in the 1950s-60s, then Eastern Europe after 2004, created this diversity.

The Bullring regeneration shows how cities can transform. The 1960s concrete shopping centre became run-down and traffic-choked by the 1990s. The redevelopment created 160 shops, luxury apartments in the refurbished Rotunda, and reconnected the area with the surrounding city through better transport links.

Birmingham's Library of Birmingham demonstrates sustainability in action. Built on a brownfield site, it recycled 95% of construction waste, employs natural lighting and ventilation, includes roof gardens for wildlife, and attracts 2.5 million visitors annually whilst promoting sustainable transport.

Key Point: The Bullring transformation shows how strategic regeneration can revitalise entire city areas.

Dynamic Development: Understanding Global Inequality

Why are some countries wealthy whilst others struggle with poverty? Development means improving living standards through better resource use, and geographers classify countries as Advanced Countries (ACs), Emerging & Developing Countries (EDCs), or Low-Income Developing Countries (LIDCs).

Economic development increases goods and services produced, social development improves human welfare, and sustainable development meets current needs without compromising future generations. The old North-South divide has become more complex with BRICS countries (Brazil, Russia, India, China) and MINTs countries (Mexico, Indonesia, Nigeria, Turkey) emerging as major economies.

We measure development using GDP and GNI for economic progress, but these have limitations - they're averages that hide inequality and miss unpaid work. The Human Development Index (HDI) combines wealth, health (life expectancy), and education (literacy rates) for a broader picture.

Climate change worsens uneven development through sea level rise, stronger cyclones, unpredictable rainfall, and drought. LIDCs suffer most from increased hunger, conflict over resources, migration, and deeper poverty.

Key Point: HDI gives a more complete development picture than wealth alone by including health and education.

Obstacles to Development and Rostow's Model

Several major barriers prevent countries from developing effectively. Trade creates gaps because Advanced Countries dominate world trade with manufactured goods, whilst LIDCs rely on fluctuating commodity prices. Most TNCs are based in rich countries, so profits flow back there even when operations occur in poor countries.

Debt can devastate LIDCs by preventing investment in health and education, though 30 countries have received debt relief since 2000. Political unrest and civil wars can set development back decades by displacing people and disrupting food production and services.

Rostow's Model shows five development stages: traditional society $farming-based$, pre-conditions for take-off (improved farming and resource extraction), economic take-off (increased industrial investment), drive to maturity (high investment and international trade), and age of mass consumption (consumer industries and personal wealth).

This model helps explain development patterns, though critics argue it's too simplistic and Western-focused. Real development is messier, with countries potentially skipping stages or moving backwards during crises.

Key Point: Political instability can undo decades of development progress, as seen in South Sudan's oil production collapse.

Zambia Case Study: Development Challenges and Solutions

Zambia perfectly illustrates development challenges facing LIDCs. This landlocked Southern African country has low life expectancy (52), with almost half the population in poverty despite abundant natural resources including copper.

Regarding the Millennium Development Goals, Zambia achieved some successes: primary school attendance increased, gender equality in education improved, HIV/AIDS infections fell, and debt relief was obtained. However, child mortality remains high, maternal deaths continue, forest cover has declined, and sanitation problems persist.

TNCs like Associated British Foods bring mixed results. Benefits include jobs, tax revenue, and efficient production. Problems include profit prioritisation over worker welfare, tax avoidance, dominance over local companies, and environmental damage.

Aid takes various forms: official development assistance from governments, voluntary aid from charities, multilateral aid through international bodies, and bilateral aid between countries. Water Aid addresses Zambia's crisis where 5 million lack clean water and 5,000 children die annually from water-related diseases.

The Kariba Dam shows top-down development's complexity. Benefits include hydroelectric power for industry, renewable energy, and new fishing/tourism industries. Costs included displacing 60,000 Tonga people, loss of fertile farmland, disrupted natural flooding, and ongoing flood risks affecting 3.5 million people.

Key Point: Zambia's 70% reliance on copper exports makes it vulnerable to global price fluctuations.

UK in the 21st Century: Population and Economic Change

Britain today looks dramatically different from 50 years ago, with changes that will shape your future opportunities. The UK's 65 million people are concentrated in cities, creating housing shortages requiring 240,000 new homes yearly (only half get built). Housing stress particularly affects south-east England due to planning restrictions, green belt protection, and rising land prices.

Physical geography still matters - mountains in the north and west receive more relief rainfall from south-westerly Atlantic winds, whilst the crowded south-east faces water stress despite lower rainfall. Long-term solutions involve piping water from high-rainfall, low-demand areas to dry, crowded regions.

The UK's demographic transition shows how populations evolve. Until the 1990s, growth came from natural increase, but 21st-century growth mainly results from net migration. Britain now faces an ageing population, requiring increased pension age, NHS funding, elderly care, and reduced family working time.

Economic transformation has replaced traditional manufacturing with tertiary and quaternary industries. Despite record employment levels, unemployment remains highest in former manufacturing regions where coal mining and textiles have virtually disappeared.

Key Point: Most UK population growth this century comes from net migration rather than natural increase.

Economic Hubs and Global Connections

Cambridge exemplifies a modern economic hub with over 1,500 biotech and internet technology firms in the London-Cambridge growth corridor. Its advantages include excellent transport links (M11, Stansted Airport), highly educated Cambridge University graduates, and outstanding quality of life. However, success brings overcrowding, traffic congestion, and soaring house prices.

Economic hubs are classified as either high growth (Manchester leads with economic, demographic, and place growth) or dynamic growth $Cambridge tops with knowledge-intensive businesses, high-skilled workforces, new business formation, and good transport connections$.

The UK maintains strong Middle Eastern interests despite losing colonial control. Growing trade, Islamic terrorism threats, and regional instability affect British security. The 2003 Iraq invasion following 9/11 led to government overthrow but ongoing power struggles, with Islamic extremists spreading from Syria seeking to establish an Islamic state.

These conflicts demonstrate how global events directly impact UK domestic security, economic interests, and foreign policy decisions. Understanding these connections helps explain why geography matters in an interconnected world.

Key Point: Cambridge's success as a tech hub shows how universities can drive regional economic transformation.
