The push pull model: decision-making Settlement: push and pull factors, intervening LEDC Cities obstacles and opportunities. N.B role of perception in decision making. Voluntary (economic migrants) versus forced migration ( refugees) Present day international refugee problem: poverty; famine; war; asylum seekers Rural to urban migration in LEDCs: Settlement: push and pull factors (incl. Perceived LEDC Cities urban opportunities) consequences of rural losses ( e.g. depopulation) and urban growth (e.g. spontaneous squatter settlements) Urban to rural migration in MEDCs: push and pull factions (incl. Perceived urban problems and rural opportunities, consequences of urban losses ( e.g. inner-city decline) and counter- urbanisation (e.g. suburbanised villages) The need to manage migration versus civil liberties Unit 3 People and Places B – Urban environments Reasons for the development of mega Settlement: cities, especially in LEDCs LEDC Cities The problems associated with the rapid Settlement: urbanisation including congestion, LEDC Cities transport, housing, health, employment Sustainable cities and crime. The growth location and problems of Settlement: shanty towns. Ways in which the LEDC Cities problems might be tackled, including self-help schemes Models of urban structure: their uses Settlement: and limitations Urban Land use Factors encouraging similar land uses Settlement: to concentrate in particular parts of the Urban Land use urban area (e.g. location needs, Settlement Hierarchy and Sphere of accessibility, land values) Influence Reasons for segregation of different socio-economic groups An awareness that such has positive aspects but can generate tensions and injustices Identification of, and the reasons for Settlement areas of social deprivation and poverty. Inner City Problems and Solutions Reasons for the decline of inner-city areas. The need for redevelopment and renewal. The nature of and reasons for the Settlement: changes which are taking place at the CBD Problems and Solutions edge of MEDC cities (e.g. shopping, Sustainable cities commercial and industrial Inner City Problems and Solutions developments). The debate ‘greenfield’ versus ‘brownfield sites; suburbanisation and counter urbanisation The urban managers: planners, Settlement: politicians, property developers, CBD Problems and Solutions industrialists Sustainable cities Inner City Problems and Solutions Unit 4 Global Issues A Fragile Environnent The fragile nature of environments ; Scheduled for new KS3 Update the concept of sustainability Causes of Soil erosion and Covered in KS3 Product desertification, drought and unreliable rainfall, human abuse of the savannah through population pressure, fuel supply and overgrazing, war and migration Consequences: Reduced agricultural Covered in KS3 Product output, malnutrition and famine Causes of deforestation: timber Covered inKS3 product extraction, agriculture, mining: transport and settlement. Consequences: impacts on forest Covered in KS3 Product ecosystems, loss of biodiversity, contribution to global warming, economic developments Managing rainforests in a sustainable Covered in KS3 Product way (e.g. agro forestry) the need for international co-operation The greenhouse effect and global Scheduled for KS3 Update warming ( including the scientific Energy: evidence) Non-renewable Energy Causes: deforestation; air pollution Scheduled for KS3 Update through the burning of fossil fusel; Energy: agricultural change CFCs Non-renewable Energy Consequences: rising sea-levels; Scheduled for KS3 Update climatic hazards; ecosystems changes, agricultural production; new employment opportunities; changing settlement patterns; health and well- being Unit 4 Global Issues B – Globalisation Globalisation and the rise of the global economy (the growth of population and commodity chains) Factors encouraging a globalised economy (trade, foreign investment, development aid, labour, modern transport and information technologies). The global shift in manufacturing and Industry: the reasons for it (the High Technology Industry growth of global assembly lines). The expansion and changing pattern of world trade in both goods and services Transnational companies (TNCs) – their organisation and role as key players in promoting the global economy. The benefits and costs to countries hosting TNCs. The growth of global tourism and its Tourism: causes (increased leisure, The Growth of Tourism modern transport, marketing).

International Tourism National Parks Unit 4 Global Issues C – Human Welfare The nature of welfare and the quality of life; measures and indicators (housing, health, access to services, the PQLI) The causes of global variations in human welfare (levels of development, resources, quality of government). The role of international aid in reducing global differences; appropriate aid (technical assistance versus loans). Rapid population growth (falling death rates and high birth rates) and its consequences for human welfare (inadequate housing and physical infrastructure; unemployment and poverty). The pressure of population on resources. Government policies to reduce rates of population growth (birth control programmes, incentives). Regional variations in human welfare within a country (indicators); the symptoms of advantaged and disadvantaged areas (growth and decline; prosperity and poverty).
