• Ink shed (5 mins): If the ecological footprint of average North American is 9.5 hectares, how much space in square kilometers would we need for every person to consume the same?

• Earth’s total population = 6,500,000,000

• 1 hectare = 0.01 km²

• Total surface area of Earth: 510,065,600 km²

• ((9.5*6,500,000,000)*0.01) = 617,500,000 km²

• 617,500,000 km² / 510,065,600 km² = 1.2 Earths!!

• Ecological footprint: measures the amount of renewable and non-renewable ecologically productive land area required to support the resource demands and absorb the wastes of a given population or specific activities.

• Global patterns of urbanization

• Differences in urbanization between MDCs and LDCs

• Urbanization and the population question

• Urban service provision and urban economies in LDC cities

• In the MDCs about 6 percent of the urban population live in slum conditions

• In the LDCs about 80 percent of the urban population live in slums (barrios, favelas, ‘spontaneous settlements’).

• Often located on undesirable, or dangerous sites: steep slopes, beside garbage dumps, or along roads and railway lines.

• 2001 Census showed 37% of urban households in India lived in one room

• In Mumbai it was 65%, with an average of 5 persons/household

• Only half the dwellings have running water and 26% have no toilet (53% in Mumbai)

• 23% of the urban population lives in squatter settlements and hovels – in Mumbai probably 8 of 12 million inhabitants live in these conditions
