5. What effect does this have on Sydney?


Population growth is the increase in the number of people who inhabit a territory or state. In sydney population is increasing and forcing the governments and communities to react. Data for the past 25 years shows that Sydney's population growth ranged from a low of 400 people per week in 1990 to a high of 1,150 people per week in 1996. A population growth of 1.2 million people or a total of 5.3 million by 2031 is assumed. On average Sydney grows by about 780 per week or around 40,000 per year. These statistics show that sydney needs solutions the increasing population and to act fast. The numbers are increasing dramatically therefore things such as urban sprawl and consolidation. The effect on sydney is large with more pressures on the public resources, congestion on roads as well as increasing the demand for needs and wants.


Urban sprawl 
Urban sprawl includes the spreading outwards of a city and its suburbs to its outskirts to low-density, auto-dependent development on rural land. Sydney and NSW is having to create new suburbs and areas for the increasing population. Between 1982 and 1997 America converted approximately 25 million acres of rural land  into developed land. That statistic shows how America has had to deal with the new immigrants and increasing population by taking out the natural land and building properties. Urban sprawls effect on sydney is large as less and less natural land is been taken out to cope with the increasing population.


Urban consolidation
The increase of dwelling densities within established areas over and above that which is already there through infill or redevelopment of existing buildings. Urban consolidation is occurring throughout sydney and in particular the north shore. houses are being knocked over and then built up into apartment blocks. Currently, 12,456 people live in the CBD, West Perth, East Perth and Northbridge. Council staffers want 95 per cent more living there - or a total of 24,289.2 people. This is showing how people want to stack these areas with the population and increase the  population in such a small area. The effect of urban consolidation in sydney is immense. It creates more traffic on the roads, pressure on local facilities. Some people might say that it effects the aesthetics on the community.

Urban Sprawl or Consolidation: Green Square

1. This is an example of Urban Consolidation as it is building up on previous land. small area building up
2. It gives people a place to live in a great location near the city and airport, its affordable, transport may not need car. Renewing a new suburb and more useful.
3. Lifestyle for cramped, congestion on roads, more pressure on public transport, limited areas of recreation.

Urban Sprawl or Consolidation: Jordan Springs

1. It is an example of urban sprawl as they are creating pretty much a new suburb off penrith
2. Negative for surrounding communities as it will create congestion and more people, positive for sydney it is allowing more people to live in the western suburbs and positive for Australia as we are dealing with the increasing population and increasing real estate prices

9.1 Questions

1. Urban Sprawl is when a city’s population is spread out more evenly across its landscape.
2. Urban consolidation is the increase of dwelling densities within established areas over and above that which is already there. This is mainly happens in cities
3. That they have a high population density, a high proportion of the population working in manufacturing and professional service-related industries.
4. Our population, Our Land area and the percentage of our population which lives along the coast line.
5. Infrastructure (housing etc), the availability to fresh water and food resources.
6. Population density refers to the population of a particular place, divided by the amount of space within that area. EG- Sydney has 3,502,000 people and covers 1687km^2, therefore its population density is 2076/km^2.
7.It has the highest population density within Australia, compared to other cities like Mumbai, it has about a tenth of the population density!
8. One of the key advantages is that electricity and water supplies are already in place so it doesn’t require extra building work and things like new pipework and new wires.
9. They’ve been innovative with their design of apartments and new estates to manage the impacts of population growth in cities.
10. (a) – Melbourne, VIC
(b) – Population within that area divided by the square kilometres within that same area.
(c) - Sydney, Melbourne, Adelaide, Wollongong, Perth, Gold Coast, Newcastle, Canberra, Brisbane, Gosford.
(d) – 8 out of the 10 major cities within Australia have a population density of greater than 1000km
11. The buildings will ruin the owners views, as well as put much greater pressure on their water and electrical supplies.
12. Advantage – You have more space and freedom
Disadvantage – It’s more expensive, living in a large complex requires less work around the house.

Year 10: Urban Renew and Decay

• Aesthetics- is a branch of philosophy dealing with the nature of beauty, art, and taste, and with the creation and appreciation of beauty.

This is a sketch of which most designers complete when creating a product such as a house. They draw this to show the outcome and whether or not people like the look of it.

• Safety- the state of being certain that adverse effects will not be caused by some agent under defined conditions

Safety relates to the world as without safety restrictions or safety in general there would be lots of deaths and injuries

• Slums-is a run-down area of a city characterized by substandard housing and squalor and lacking in tenure security.

This picture is an example of slum in india, people have to live in slums with sometimes no water, food and very little shelter their whole life

• Decay- the process of gradually becoming inferior

Everything over time decays in some form and as we see above a house that has gradually worn away

• Reconstruction and renewal- the activity of constructing something again and renewal or reclamation is the conversion of wasteland into land suitable for use of habitation or cultivation

Weather and other extreme conditions can cause destruction in the world of ours and eventually the process of reconstruction will have to come in. Here we have a man reconstructing his house after the roof was removed by a cyclone

• Transport- move something or somebody around; usually over long distances

Transport gets people around cities and countries over long distances or short in a small space of time. Above are examples of transport

• Suburbanization- urban growth caused by the creation of new suburbs at the outer edges of the city

Suburbanization can affect cities greatly by creating polution, congestion and other problems. Above we have a new suburb created.

• Environmental factors- are those determinants of disease that are not transmitted genetically. In more basic terms, an environmental factor is a caused, aided, or triggered by the environment.

Environmental factors such as above flooding affect our cities emmensely, loss of house, food and water and even life

• Light and sound- two things that affect our senses such as sight and hearing

7.8 Dune Revegetation at Stuarts Point

1. Stuarts Point stabilisation area, it is small coastal village located on the mid-north coast of NSW. The dune area is 5km long with a width of 200-400m varying.
2.

• 1970 the scheme started
• Large flood caused the river to break through the sand barrier at southwest rocks
• Silt build up due to longshore drift
• Grassy head gave access to dunes
• Closure of river lead to cattle grazing
• sand removed by wind
• Dunes were attacked by heavy seas

3. The role of the community is to conserve the barrier and to look after the soil. The people in the community is to check up with the soil conservation service.
4. The sand barrier is important because they need the barrier so their tourism and fishing industries can survive, the barrier also protects weights
5.There is primary, secondary and Tertiary species of plants on a sand dune, grassers and creepers belong to the Primary species, shrubs and short-lived trees live in the secondary species and Long-lived trees live in the Tertiary species.

 6. The majority of roots from the vegetation help stabilise the sand dune area.
7. Cattle grazing had a devastating impact as they continually destroyed the sand drift control.
8. It would have destroyed the incipient dunes, which means the primary species of the area would have lost their homes. It destroyed many habitats.
9.The Department of Public Works,The Department of Lands, the Macleay Shire Council, and the Soil Conservation Service of NSW.
10.The main stages in the management program was using a tractor to form a dune 1.8metres high on top of which a fence was constructed to protect the hind dunes.
12. The water just destroyed the entire area
13.       a) It was very successful in restabilising the sand dunes  
             b) The Macleay river entrance was destroyed by the removal of the vegetation
             c) It had a very positive impact on the local communities
