Urban problems Housing problems
Definition Housing is not only a shelter to weather, but also includes access to such basic services as electricity, water and transport. Therefore, problem occurs when the quantity and quality of provision of housing do not reach satisfactory levels.
Functions performed by a house as residence a shelter that protects the residents from environmental hazards a place where residents can enjoy privacy a place where essential physical, psychological and social needs are satisfied.
Criteria to assess the standard of a house building materials used and the construction method, which determine the house’s ability to protect its residents living density, as measured by number of people per room. This determines the degree of privacy enjoyed by individuals availability and quality of facilities in the houses. These are essential for meeting various needs of the residents
RURAL-URBAN MIGRATION OVERSEAS MIGRANTS CBD Inner city LDC City MDC City Outward migration of higher-income group
Inadequate quantity of housing common in LDC cities demand for housing exceeds supply, leading to housing shortage / housing attainability --> overcrowding
Poor quality of housing common in both LDC and MDC cities urban slums = legal, low-rent housing in inner city areas squatters = illegal (usually not rent-paying) housing in inner city areas / at city margins / on hillslopes
Urban decay common in both LDC and MDC cities substandard and derelict buildings poor sanitation / inadequate facilities congested / overcrowding living condition / high building density narrow streets / traffic congestion lack of recreational space / parks / social facilities lack of planning / mixed land use environmental pollution / environmentally degraded poor aesthetic value fire hazards social problems like family conflicts / mental distresses / theft / vandalism urban ghetto / racial segregation
1.1.1Causes and Impacts of Housing Problem in LDCs Inadequate quantity Large natural increase Rapid rural-urban migration from rural push factors Over-population and pseudo-urbanization
1.1.1Causes and Impacts of Housing Problem in MDCs Housing demand > supply Keen competition of land uses Second World War Overcrowding
rural-urban migration and overseas in-migration started in the early 20th century The nowadays' most affected destinies are the USA, UK, South Europe The immigrants usually come from Africa, China, Eastern Europe, South America and Middle East. United States - Inflow of foreign-born population from Asia (total) as a percentage of total inflow: 1984 – 37.9%; 2004 – 35.7%
limited space but keen competition among different land users economic development pushes the urban land value up forcing many low- income residents and high proportion of minority groups to live in slums in inner city areas
Second World War many houses were seriously damaged and destroyed during WWII. The housing stock was badly depleted.
Overcrowding overcrowding and tenants sub-letting their units mainly occur in older housing near the CBD --> forming slums in inner city areas
Substandard housing Socially, both slums and squatter housing are a reflection of unequal access to urban resources because squatter residents belong to the low-income, poor, socio- economically and politically marginal group in society.
Slums they are found in transition zones next to the CBD, where houses are deteriorating, without adequate amenities the tenants are too poor to improve the living conditions
Slums in MDC cities, landlords have moved out to the suburbs (suburbanization of the high-income groups) due to improved transport links some areas are ghettos of minor racial immigrant groups some industries have relocated to the suburbs (suburbanization of industrial activities) local government has little income from tax to improve the living environment
Squatters they are illegal, temporary housing found on roof tops hillslopes fringing the urban areas and on stilts or boats in the sheltered coastal areas near the city
Squatters they are usually the result of a large influx of new-comers / rural migrants to the city and also be the population growth of the poor
Squatters squatters settlements are known as “shanty towns” which are characterized by: scrap materials, e.g. wood and metal sheeting insufficient basic services, e.g. sanitation, water, electricity overcrowded settlements
Poor living environment Environmental pollution due to the mixed land use (workshops and retail units + residential units) land-use conflicts poor air quality + noise and land pollution Fire and health hazards these squatter huts are built of wood and cardboard there are no surface roads / electricity supply / water and sewage facilities creating fire and health risks Social problems family conflicts mental distresses theft, robberies, crimes, vandalism ethnic and social segregation
Solutions to housing problems New town development Urban renewal Slums / squatters clearance Provision of more housing
New Town development new town = a planned community aiming at solving certain problems, e.g. population redistribution
Tin Shui Wai
Tseung Kwan O
Factors of new town development to relieve congested urban areas to decentralize industries for land use separation for administration purpose
New town development The development of new towns / satellite towns general involves the outward movement of urban residents to the peripheral areas.
New town development However, not all the residents are willing to move though they are suffering from rather poor living environment because they cannot afford the higher rent in the new town they have to spend more time on journey-to- work they have to pay higher transport cost in journey-to-work
New town development Therefore, new town development / satellite towns must be associated with the process of industrial decentralization. In this way, people moving outward may find their new jobs in the surrounding areas easily.
Successful in HK? New towns green towns Can multiple-nuclei really help? Heavy commuting traffic nowadays Tin Shui Wai = City of sorrow?
Redevelopment = the demolition of bad housing Rehabilitation = involves improvement of existing old buildings and environment rather than demolition of buildings
What is rehabilitation? Rehabilitation includes the renovation and management of buildings, such as improving external appearance of buildings by cleaning and repairing fitting new windows and new doors installing indoor toilets and baths redesigning recreational areas
Rehabilitation causes less disruption to residents less social disruption and resentment involves less financial cost, especially compensation helps preserve and restore buildings of cultural, historical and architectural value the living environment is greatly upgraded
slum / squatter clearance replaced by public housing to solve the problems of landslides / fire hazards / poor living conditions
building more adequate houses through public organizations, e.g. Housing Authority / Housing Society in Hong Kong or private sectors / developers
Ultimate solution Sustainable city development = "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." ["Our Common Future", 1987] finding ways to increase prosperity and improve the quality of life while reducing overall pollution and waste; meeting our own needs and aspirations without doing damage to the prospects of future generations; and reducing the environmental burden we put on our neighbours and helping to preserve common resources. ("1999 Policy Address")
Recent issues Land use conflicts Siting of dangerous / undesirable industries Locational advantages / disadvantages Urban planning building density / height Reserve 20% space below the ridgeline Cityscape / streetscape Preservation vs economic development
Why building government headquarters at Tamar site? Long-term solution to the acute shortage of office space faced by the Government Secretariat and LegCo The new Central Government Complex will provide centralised accommodation for the offices with core policy formulation functions and thereby enhance the operational efficiency of the Government Secretariat. The new Legislative Council Complex will provide sufficient office space and improved facilities for Members and staff, and also room for future expansion where necessary. Enhancing vibrancy of waterfront and opening up the site for the public's enjoyment The Tamar project will enhance the appeal and vibrancy of the harbourfront area and convey Hong Kong's position as Asia's world city. The open space will be integrated with the adjoining waterfront promenade to provide about 10.8 hectares of recreational area along the Central waterfront for the public's enjoyment. Job creation About 2,700 jobs will be created.
