    • Managing change in the human environment Rural-urban migration in LEDCs What are the effects of rural-urban migration in LEDCs?
    • What are the problems in LEDC cities? Poverty – for most people in cities Overcrowding – particularly bad in shanty towns with extended families living together Power supplies – inadequate, often illegal Pollution – of water, land and air is “normal” Education – provision varies but shanty town children less well educated than other children Rubbish – infrequently collected but may be used by local population Sewage systems – inadequate or nonexistent, tracks become open drains Clean water – scarce, often from a standpipe or brought at high cost Housing – made out of anything in shanty towns Traffic congestion – shanty towns have especially poor road access Violence and intimidation common Healthcare – scarce and expensive, disease spreads quickly
    • LEDC City Plans The shape of most LEDC cities is irregular, with expensive housing near the CBD and the biggest area of land covered by shanty towns. Shanty towns or informal settlements grow quickly on land not already used. The pattern is different from LEDC cities Industry extends along line of communication, in particular roads.
    • What happens to rural areas when people leave? • Download spiral of poverty from those left behind, particularly for the dependent old and young. • Families may survive on money from workers who migrate to the cities. • Commercial agriculture (e.g. in the sugar cane area of SE Brazil) can displace families and villages.
    • C LE D Rio de Janeiro, Brazil • Population: 11 million • 25% live in favelas (shanty towns/informal settlements). Informal settlements vary from very poor conditions to almost permanent suburbs of cities. Early favelas were built on hillsides, but poor drainage, deforestation and erosion caused hillside collapse and every year people were killed. In Rocinha (population 100,000) well established favelas, which are solidly built, but not overcrowded and congested. There are some facilities – healthcare, shops and schools – but roads are narrow tracks and water and power supplies are scarce. Crime, air and water pollution are serious issues.
