- 1UrbanisationA process where an increasing proportion of the population lives in towns and cities, resulting in their growth
- 2Rural-to-urban MigrationMoving home from a rural area to settle in a town or city
- 3Causes of Urbanisation-Natural increase, people in the cities have children, so the city grows
-Rural-to-urban migration, people move from rural areas to cities, so the city grows - 4Reasons for Rural-to-urban Migration-Push factors that cause people to leave rural areas like
-E.g. drought, few opportunities, bad infrastructure, poor medical facilities, little recreation, unemployment
-Pull factors that attract people to urban areas
-E.g. opportunities, education for children, jobs, infrastructure, transport, medical facilities, recreational activities - 5Burgess Model

-Multicultural Mix - 13Brownfield SiteLand that has been built on before and is now to be cleared and reused, normally in the inner city
- 14Greenfield SiteLand that has not been built on before, usually in the country side of rural urban fringe
- 15Brownfield Sites: Advantages-Easier to get permission
-Sites are not left derelict
-Utilities such as water and electricity already provided
-Roads already exist
-Near to facilities
-Shorter commute time - 16Greenfield Sites: Advantages-Cheaper to prepare as no clearing is required
-No restrictions of already existing road networks
-Pleasant country side environment
-More space for gardens - 17Housing: Issue-UK population increased by 10.5% since 1971
-Number of household increased by 30% (more people living alone)
-New, single person housing accounts for 70% of rising housing demand
-People leave home earlier, marry later and divorce is more common
-Demand is more than supply so housing prices rise - 18Housing: Solution-Government has a target to build 240 000 new houses every year by 2016 so prices don't spiral out of control
-Target of 60% to be built on brownfield sites
-Some will have to be on greenfield sites though - 19Inner City: 1) UDCsUrban Development Corporations

-Providing facilities where all sections of community are encouraged to meet - 27Causes of Squatter Settlements-Squatter settlements occur as an evolution of the informal sector
-Rapid rural to urban migration doesn't allow the time to build proper housing

-Infrastructure is laid out ahead of time
-People can then build houses on these plots with whatever they can afford at the time
-They can then improve the houses later - 32Improving Conditions: Local Authority Schemes-Can take many different forms
-Can be large scale, involving the building of:
-Schools
-High rise flats
-Entire new settlements - 33Kibera: Location and Size-Kibera is a squatter settlements in the south of Nairobi, Kenya's capital

-Electronic waste
-Water pollution
-Waste and pollution - 37Why do these issues exist?-Rapid urbanisation makes it harder to control what's happening and enforce regulations
-Not enough people to enforce the regulations on a growing population
-Non existent or poor regulations make matters worse - 38Water Pollution: Ganges-Ganges river has toxins, chemicals and dangerous bacteria at 3000 times the rate that WHO suggests as safe
-1 billion l of untreated sewage pumped into Ganges DAILY
-This is predicted to double in the next 20 years

-Set up electrical crematories - 43Dealing with Waste Disposal-Sao Paulo, Brazil has two large incinerators that burn 7 500 tonnes of waste a day
-Shanghai, China has an effective solid waste disposal unit in houses which is then used as fertiliser nearby - 44Dealing with Air Pollution-Need to reduce the emissions of sulphur dioxide and oxides of nitrogen
-Switching to cleaner energy sources works, but this will probably require the implementation of a carbon tax
-Shanghai uses low sulphur coal
-Increasing public transport and it's popularity also helps - 45Sustainable CitiesAn urban area where residents have a way of life that will last a long time. The environment is not damaged and the economic and social fabric can stand the test of tome
