[Option G] 1. The variety of urban environments

Distinguish between the site and situation of an urban settlement. [2]

Site: The physical characteristics of the land on which a settlement is built, such as relief, altitude or proximity to a river. [1], whereas ... Situation: The settlement's location in relation to other places or features, such as major transport routes, markets or neighbouring cities. [1] Example: Hanoi's site includes the low-lying Red River Delta, while its situation includes its connections to other settlements in northern Vietnam.

Explain one physical factor influencing the location of an urban settlement. [2]

Relief: Flat or gently sloping land is easier to build on [1], therefore reducing construction costs and making the area more suitable for housing, industry and transport infrastructure [1].

Explain one reason why river valleys often have high population densities. [2]

Rivers provide a reliable water supply [1], therefore supporting domestic use, agriculture and industry and making surrounding areas attractive for settlement [1].

Explain two factors influencing the growth of urban settlements. [4]

Factor 1 - Employment: Cities provide a concentration of industrial and service-sector jobs [1], attracting rural-urban migrants and increasing urban population size [1]. Factor 2 - Transport: Improvements in transport infrastructure increase accessibility [1], encouraging businesses to invest and allowing settlements to expand into surrounding areas [1].

Distinguish between a megacity and a spontaneous settlement. [2]

Megacity: An urban area with a population exceeding 10 million people [1]. .. whereas ... Spontaneous settlement: A residential area that develops without formal planning or authorisation, often with limited infrastructure or secure land tenure [1].

Explain two ways the function of a city can influence its characteristics. [4]

Way 1 - Industrial function: Industrial cities require factories, warehouses and transport links [1], creating large areas of industrial land use and attracting workers [1]. Way 2 - Administrative function: Capital cities concentrate government offices and public institutions [1], encouraging the development of commercial services, transport infrastructure and employment [1].

Explain how urban settlements can be organized into a hierarchy. [2]

Urban settlements can be ranked according to their population size and range of functions or services [1]. Larger, higher-order settlements generally provide more specialized services, such as major hospitals and universities, serving a wider surrounding population [1].

Explain one reason why central business districts (CBDs) are often highly accessible. [2]

Major transport routes frequently converge in the CBD [1], allowing large numbers of workers, shoppers and businesses to access the city centre [1].

Explain two reasons why commercial activities are concentrated in CBDs. [4]

Reason 1 - Accessibility: CBDs are connected to major transport routes [1], allowing businesses to access large numbers of workers, customers and other firms [1]. Reason 2 - Agglomeration: Businesses benefit from locating close to one another [1], because they can share services, customers and suppliers, potentially reducing costs and increasing business opportunities [1].

Explain how land values influence land use within urban areas. [2]

Land values are often highest in accessible city-centre locations [1], therefore high-profit activities such as offices and retail are more able to afford these sites than activities requiring large areas of cheap land [1].

Explain two factors influencing the location of industrial activities within urban areas. [4]

Factor 1 - Land values: Industry often requires large sites for factories and warehouses [1], encouraging businesses to locate in cheaper peripheral areas rather than expensive CBD locations [1]. Factor 2 - Transport: Industrial activities benefit from access to major roads, ports or railways [1], reducing the time and cost of transporting raw materials and finished products [1].

Explain two reasons why retail activities may relocate away from the CBD. [4]

Reason 1 - Land costs: Land and rental costs may be lower in suburban locations [1], allowing retailers to construct larger stores with parking facilities at a lower cost [1]. Reason 2 - Accessibility: Ring roads and motorway connections improve access to suburban shopping centres [1], allowing customers to travel by car without entering congested city centres [1].

Explain how urban planning influences the distribution of economic activities. [2]

Governments can introduce zoning regulations that allocate areas for industrial, commercial or residential use [1], therefore concentrating particular activities in designated locations and reducing incompatible land uses [1].

Explain two factors that may cause changes in urban land use over time. [4]

Factor 1 - Deindustrialization: Factories may close or relocate to cheaper locations [1], leaving former industrial sites available for redevelopment into housing, offices or leisure facilities [1]. Factor 2 - Population growth: A growing urban population increases demand for housing [1], encouraging residential development and the conversion of previously agricultural or vacant land [1].

Explain one physical factor influencing residential patterns within a city. [2]

Areas at risk of flooding may have lower land values and attract lower-income housing [1], because wealthier households may prefer safer locations with lower exposure to natural hazards [1].

Explain two reasons why wealthier residential areas may be concentrated in particular parts of a city. [4]

Reason 1 - Environmental quality: Wealthier residents can often afford housing near green space or in less polluted areas [1], improving access to recreation and residential environmental quality [1]. Reason 2 - Accessibility to desirable services: Areas with good schools, healthcare and transport connections are often more desirable [1], increasing housing demand and prices and potentially excluding lower-income residents [1].

Explain how land values influence residential segregation. [2]

High land values increase the cost of purchasing or renting housing [1], therefore lower-income households may be priced out of desirable neighbourhoods and concentrated in more affordable locations [1].

Explain two factors responsible for residential segregation within urban areas. [4]

Factor 1 - Income: Higher-income residents can afford more expensive housing in desirable neighbourhoods [1], creating geographical concentrations of wealthy and lower-income households [1]. Factor 2 - Ethnicity: Migrants may choose to settle near established communities sharing their language or culture [1], allowing access to social networks, cultural facilities and employment support and creating ethnic clusters [1].

Explain two ways urban planning can influence residential patterns. [4]

Way 1 - Zoning: Planning regulations designate areas for residential development [1], determining where new housing is constructed and influencing population density [1]. Way 2 - Affordable housing: Governments may construct subsidized housing in particular districts [1], improving access for lower-income households and potentially changing the socioeconomic composition of neighbourhoods [1].

Distinguish between urban poverty and urban deprivation. [2]

Poverty: A lack of sufficient income or material resources to meet basic needs [1]. Deprivation: A broader lack of access to essential opportunities and services, such as adequate housing, healthcare, education or employment [1].

Explain one reason why informal economic activity is common in rapidly urbanizing cities. [2]

Formal employment opportunities may not increase as quickly as the urban workforce [1], therefore residents may turn to informal activities such as street vending to earn an income [1].

Explain two opportunities provided by informal economic activity in urban environments. [4]

Opportunity 1 - Employment: Informal businesses create opportunities for people unable to access formal jobs [1], allowing households to earn an income and support basic living costs [1]. Opportunity 2 - Affordable services: Informal businesses may provide low-cost goods, food and transport [1], improving access to everyday services for lower-income urban residents [1].

Explain two challenges associated with informal housing. [4]

Challenge 1 - Sanitation: Informal settlements may lack adequate sewage systems and clean water [1], increasing exposure to waterborne diseases and other health risks [1]. Challenge 2 - Insecure land tenure: Residents may lack formal ownership or legal permission to occupy their homes [1], increasing the risk of eviction and discouraging investment in housing improvements [1].

Explain two reasons why the incidence of urban deprivation varies between cities at different levels of development. [4]

Reason 1 - Infrastructure: Wealthier cities often have greater financial resources for water, sanitation and healthcare systems [1], reducing some forms of deprivation through improved access to essential services [1]. Reason 2 - Rapid growth: Some industrializing cities experience population growth faster than infrastructure can expand [1], leading to overcrowding, informal housing and inadequate service provision [1].

Explain two reasons why poverty and deprivation may be concentrated in particular urban neighbourhoods. [4]

Reason 1 - Affordable housing: Low-income households may be restricted to cheaper housing [1], concentrating poverty in neighbourhoods with lower property values or poorer environmental conditions [1]. Reason 2 - Limited employment: Some neighbourhoods have poor access to jobs and transport [1], making it more difficult for residents to gain employment and escape poverty [1].

Explain one reason why urban poverty does not always lead to informal housing. [2]

Some cities provide social or subsidized housing for low-income households [1], allowing residents with limited incomes to access formal accommodation rather than unauthorized settlements [1].
