  • Mega-cities
    • Challenges
      • Growth can fuel political pressure for change.
      • Rapid growth of population often outstrips growth in resources and infrastructure available.
      • LIC's sprawl in haphazard fashion
      • Challenges in employment
      • In LIDC's, overpopulated slums exhibit high rates of disease due to unsanitary conditions, malnutrition, and lack of basic health care
      • The process of urbanisation presents enormous challenges to governments, social and environmental planners, architects, engineers and the inhabitants of the megacities
      • Traffic jams, poor air quality and increasing health risks, make life in megacities more difficult
      • The destruction of our environment and poverty are two other concerns, which city administrations have to take care of, as especially the poor do not have the necessary financial background to tackle these problems.
      • in some cases severe infrastructural deficits, high concentrations of industrial production, signs of ecological strain and overload, unregulated and disparate land and property markets and insufficient housing provision,
      • in some cases extreme socio-economic disparities - as well as a high level of dynamism in all demographic, social, political, economic and ecological processes.
      • In megacities there is high population concentration and density, with extreme levels in some cases, largely uncontrolled spatial expansion, high traffic levels,
    • Oppurtunities
      • High Pay Jobs
      • Better levels of education and healthcare = improves lives of the poorest
      • Offer opportunities to expand service access (healthcare) d
      • Prospects of better life leads to increased rural-to-urban migration
      • Less environmentally damaging to provide transport, housing ect... for densely packed urban areas than dispersed rural population
      • Megacities also offer great chances: according to the OECD Mexico City and São Paulo produce around 50% of the income of their countries. Bangkok contributes more than 40% to the GDP, although it is home only to 10% of the population of Thailand.
      • One must nevertheless be wary of generalizing statements, for among megacities there are clear differences in infrastructural quality,
      • the level of economic development (e.g. transformation processes), social polarisation or political leadership and governability, differences which should not be ignored.
