Mega cities • the nature, character and spatial distribution of mega cities in the developing world • the challenges of living in mega cities such as housing, traffic infrastructure, water and power supplies, sanitation services, employment, and other social and health issues • the responses to these challenges such as self-help projects, community self-government, cooperation from NGOs, urban protest and the operations of informal economies.
Urban dynamics • the urban dynamics of change: suburbanisation, exurbanisation, counter urbanisation, decentralisation, consolidation, urban decay, urban renewal, urban village, spatial exclusion. • a case study of the results of the urban dynamics in a large city selected from the developed world including its – social structure and spatial patterns of advantage and disadvantage, wealth and poverty, ethnicity – changing economic character, nature and location of residential land, commercial and industrial development – culture of place as expressed in the architecture, streetscape, heritage architecture, noise, colour, street life, energy, vitality and lifestyles – growth, development, future trends and ecological sustainability • a case study showing one of the urban dynamics listed above, operating in a country town or suburb.
use geographical skills and tools such as • calculating population density using maps of a large city • constructing a transect to show land use change in a local area • describing patterns, linkages, networks and change, using maps of large cities and other urban areas • constructing and interpreting choropleth maps • synthesising and evaluating fieldwork data about the dynamics of change in a country town or suburb • interpreting trends from logarithmic and semilogarithmic data about the growth of mega cities • analysing population pyramid data to investigate the implications on health and social issues of a rapidly growing city • calculating the time of day when a photograph was taken and relating a photo to a map of a streetscape.
identify geographical methods applicable to and useful in the workplace such as • using GIS, satellite imagery and aerial photography • analysing maps including topographic, cadastral and land use maps • collecting and analysing urban field data • the relevance of a geographical understanding of urban places to a particular vocation such as: urban and regional planning, designing effective city infrastructure, planning the delivery of social services, monitoring environmental quality and sustainability, preserving heritage sites.
Rates of Urbanisation: - More and more people are attracted to city centres globally. - Two centuries ago less than 5% of the world’s population lived in cities and towns. Today that figure approaches 50%. - The number of cities with a population over 1 million has increased from 2 in 1850, to 109 in 1970, and is expected to be 380 in 2010.

World City: a city that has global and national significance Mega city: a very large agglomeration of at least 10 million people Urbanisation: an increase in the proportion of a country’s population living in urban areas.
