Population-migration/urban problems
2
Explain the following terms: Emigration Immigration Refugee Asylum seeker Donor country Host country Push factors Pull factors Barriers to migration Forced/voluntary Internal International
3
Effects of rural –urban migration(developed) BMW-GDA- BRAINDRAIN-ECONOMICALLY ACTIVE AGE GROUP LEAVING.GREYING POP LEFT BEHIND-rural depopulation AMALGATION OF SERVICES- P.O,SCHOOLS,BUSES ABANDONMENT OF AGRICULTURAL LAND LOWERING BIRTH,MARRIAGE RATES POLITICAL AND ECONOMIC ISOLATION Remember push factors URBAN SPRAWL-growth of dormitory towns (few high rise buildings in Dublin)-commuters Increased cost of living TRAFFIC CONGESTION PRESSURE ON SERVICES HIGH POPULATION DENSITY ECONOMIC IMBALANCE INWARD MIGRATION OF YOUNG,SKILLED WORKERS. Remember pull factors
4
Effects of rural-urban migration(developing) Rural IndiaKolkata Migration of young people,elderly left behind. Less pressure on the land Lowering of marriage and birth rates Rural depopulation Growth of mega cities- Mumbai(20m),Kolkata(16m) Urban sprawl Pressure on services- water,sewage,refuse, transport. Development of bustees/pavement dwellers- very high poulation density Child labour Social stratification
5
Impact of migration on donor and host countries-positive DonorHost Remittance home- especially poorer countries. Bringing home learnt skills- benefit local economy eg.medicine-nurses doctors,education etc Solution to unemployment in donor country,less people on social welfare. Need workers -skills shortage(nurses),unskilled workers lower paid(waitresses) Ireland 2005 needed 45,000-construction workers. New market for businesses here-taxes,need services goods etc. Ethnic diversity-multicultural society, enhance us less conservative
6
Negative effects DonorHost Braindrain of best skilled,young eg.Poland one doctor skilled in particular area nobody to replace. Smaller home market-ones with disposable income Rural depopulation-leading to closure of services for pop left behind. Pressure on services(hospitals) Exploitation-lower paid etc-Irish ferries Integration-racism Schools-language Also see notes on economic & cultural effects of membership of E.U.

Urban problems Urban sprawlTraffic congestion
9
Urban problems and solutions pg: Traffic congestion Urban sprawl,urban decay and the absence of community Heritage issues Environmental quality
10
Traffic movement and congestion-causes pg.87/88 Inadequate public transport system-needs to be integrated Car dependent society,Increase in car ownership-Dublin pop of 1.6 million-most heavily populated county in Ireland- nodal/ focal point(over 402 cars per 1,000 people in Ireland) Economic growth-greater number of H.G.V Commuters-dormitory towns(highest rate in E.U)-urban sprawl-cost of living in Dublin Effects-social,economic,environmental problems- noise,safety,loss of profits,air pollution
11
Strategies /solutions Congestion charge-london 2003(reduced traffic by 30%) Permit system-mexico city-no drive days depending on digit of your plate-unsuccessful Strategies in Ireland under planning : Transport 21(2005-2010) and N.D.P.
12
Solutions cont. Traffic management methods: Ban on HGV through Dublin city centre at certain times -2007 Port tunnel(2006) Removal of toll on M50 Widening/upgrading of M50 New interchange at red cow roundabout Other measures-roundabouts,by- passes,park and ride
13
Solutions cont. A well Integrated efficient,reliable and cheap public transport system contributes to lowering traffic congestion- Luas(2004),Dart,Bus lanes-QBC,Metro North(postponed due to downturn in the economy) New leap card Cycle to work scheme,bicycle lanes Bike rental operation-Dublin Bikes-self service bike rental system-42 stations,pay using a smartcard-extremely successful. Dublin Bike RentalDublin Bike Rental
14
Urban sprawl-pg.91,92 Urban sprawl is the rapid spread of housing from cities into the surrounding countryside. 2006 Dublin was cited by the E.E.A as an example of the worst case of urban planning. Dublin has nearly the same surface area as Los Angeles (4 million pop). Copenhagen has ½ land area of Dublin yet the same pop-Dublin has 8 houses per hectare-low compared to Europe. Dublin “all over Leinster”
15
Urban sprawl Reasons for urban sprawl- Rural to urban migration Immigration Economic growth Increase in car ownership-commuter belt. Overspill of pop need to be accomodated
16
Urban sprawl-consequences Rezoned farmland-new ”cash crop” during the boom.land on the edge is rezoned for residential,commercial and industrial use.Small villages on edge swallowed up-Tallaght and Swords.Division between rural and urban becomes blurred. Monotonous suburban area-Concrete jungle of housing estates. Increased traffic congestion-from commuter belt. Pressure on services-waste disposal,sewerage,telecommunications and water supplies.
17
Consequences of sprawl for rural areas. Loss of agricultural land Loss of wildlife habitats Loss of ancient monuments and historic landscapes(carrickmines castle m50) Growth of dormitory towns.
18
Urban problems Urban decayAbsence of community
19
Urban problems Urban decayAbsence of community Old inner city buildings in need of demolition or repair. Many problems- heating,damp,unemploym ent,crime,vandalism.anti social behaviour New sprawling housing estates-young move, older left behind-ageing population-leading to areas of urban decay. Commuters too tired to get involved in community in housing estates-some of these now “ghost estates”
20
Solutions to urban problems Urban renewalUrban redevelopment Replaces,upgrades decaying buildings,landuse is not changed. Case study-Ballymun pg.90,98 Moyross in limerick People rehoused, old buildings demolished and rebuilt for commercial use. Paris –schema directeur Docklands in most cities- quays in Waterford IFSC in Dublin along the Quays. NDP and NSS-gateways and hubs
21
solutions Ballymun regenerationParis-schema directeur
22
Urban solutions National spatial strategy 2002-2020 Balanced regional development Gateways and hubs New towns- Adamstown
