Urbanization & the population question • 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!!
Urbanization & the population question • 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. http://www.footprintnetwork.org/gfn_sub.php?content=footprint_overview http://www.adbusters.org/metas/eco/truecosteconomics/footprint.html

Outline • 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
Urban service provision • 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.
Different Models: India (Mumbai) • 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
