The Urban Climacteric

  • Concept of Urbanization:

    • Cities are critical in our age, shaping human experience and identity.

    • Reference to Onookome Okome illustrating that urbanization is a pivotal moment in human history comparable to the Neolithic and Industrial revolutions.

    • Urban birth and migration events (e.g., births in Ajegunle, young man moving to Jakarta) signify unnoticed changes in global demographics.

  • Demographic Shift:

    • Anticipated global urban population surpassing rural for the first time, whose exact moment is ambiguous.

    • This historical transition allegedly has already occurred due to inaccurate capture of census data from developing countries.

Statistics on Urban Growth

  • Global Urban Population:

    • Rapid urbanization noted since 1950, where urban growth has exceeded expectations:

    • 1950: 86 cities over 1M population.

    • Present (as of predicted 2015): 400 cities, with projections stating there could be at least 550.

    • Urbanization aligning with a soaring population of 3.2 billion in cities today, larger than the global population when JFK took office.

    • Predictions suggest the peak population could reach 10 billion by 2050, all driven primarily by urban growth.

  • Urban vs. Rural Population:

    • Rural population reaches maximum and expected to decline post-2020, resulting in cities garnering future growth.

Megacities and Desakotas

  • Developing Countries Urban Expansion:

    • 95% of growth will occur in urban areas of developing economies, aiming for a population doubling to nearly 4 billion.

    • Combined urban populace of China, India, and Brazil is comparable to Europe and North America today.

  • Comparative Growth Rates:

    • Urbanization in developing areas far exceeds that seen in Victorian Europe (e.g., Dhaka, Kinshasa, Lagos 40 times larger than 1950 populations while Victorian cities grew by a factor of 7).

    • China leads urbanization with unprecedented speed, outpacing all of Europe during the 19th century.

Figures Illustrating Urban Growth

  • Visual Representation:

    • Figure 1: World Population Growth from 1950 to projected 2030, reflecting growth in urbanized and rural populations.

    • Figure 2: Comparative population statistics of major global cities from 1950 to 2004 highlighting megacities' sizes.

Definition of Megacities:

  • Megacity: A metropolitan area with a minimum population exceeding 8 million.

  • Hypercentric Megacities: Cities like Tokyo and projected to have populations over 20 million (the urban population estimated during the French Revolution).

    • By 2025, numerous Asian cities (Jakarta, Dhaka, Karachi) expected to exceed thresholds for megacities and hypercities (with Karachi reaching 26.5 million).

Emerging Urban Networks:

  • Connections Between Cities:

    • Development of vast urban networks and corridors (e.g., Rio/Sao Paulo, Mexico City conurbations) creating larger megacity clusters affecting demographic and economic patterns.

    • Prediction that regions like West Africa rapidly ascending to high population concentrations, merging urban centers into a megalopolis along Gulf of Guinea.

Urban Poverty Dynamics

  • Proliferation of Slums:

    • Significant population marginalization in newly urbanized areas indicating a future where urban poverty will surpass rural impoverishment by 2035.

    • Rise to 2 billion slum-dwellers anticipated by 2030, possibly 45 to 50% of total urban dwellers experiencing poverty.

Current State of Urbanization Impact

  • Nature of Urbanization:

    • Urbanization characterized by the layering of features distinct from historical processes.

    • Blurring of urban-rural boundaries showing transformation in social structures and economies; rural towns evolving into urban-like environments (in-situ urbanization).

Adjustment and Response in Global South

  • Structural Adjustments:

    • IMF's SAPs linked to severe urban poverty and dislocation of traditional urbanites, correlating with growth of informal economies and sectors amid de-industrialization (especially significant in Africa).

    • Urban growth portrayed paradoxically against backdrops of economic contraction, showing ongoing rural migration despite economic turmoil.

Gender Dynamics in Urban Poverty

  • Women's Labor in Urban Contexts:

    • Women bear disproportionate burdens of structural adjustments, heavily contributing to household economies.

    • Urban environments perceive women as critical labor sources, often forced into informal economies to survive.

Conclusion: Future Urban Projections

  • Overall Urban Landscape:

    • 21st-century cities primarily constructed out of makeshift materials rather than modern infrastructures, emphasizing an emerging trend that ties urban sprawl with chronic poverty and slum development.

  • Poverty Projections in Urban Contexts:

    • By 2015, significant increases in urban slum populations recognized as a major challenge for global urban strategies moving ahead.
