A proliferation of what has been termed 'ghost cities'
suggests that China's approach to urbanisation leaves a lot to be desired. This
approach, characterised by the notion of 'build it and they will come,' has
seen large scale cities erected on the rural urban fringes in order to
accommodate the projected transition of residents from rural to urban areas.
Capable of accommodating millions of people, they are left largely uninhabited,
with occupancy rates floating around the 10% mark. This is due to the fact that
policies and processes underpinning construction are not sustainable. Firstly,
Chinese policy stipulates that residents are restricted to investing their
money in China, resulting in a massive over supply of the market. This problem
is exacerbated due to the fact that from an economic perspective, the
development is largely out of reach of the unskilled rural population it is
intended for. Unlinked from market demand, this rapid growth in infrastructure
investment is unsustainable and needs to moderate in the future, preferably
through more efficient and densely populated cities that require less
infrastructure.

Week 12.2 - Liveability
The liveability of a city is directly proportionate to the
degree which it can be considered sustainable. As a consequence, with its wide
footpaths, tree lined streets and readily accessible amenities, Barcelona is
often considered one of the world's most sustainable cities, even with a
population density of 50-70,000 people per square km. In accordance with an
efficient public transport network, effective land use planning is able to
reduce the reliance on private vehicle ownership, and in turn, negative
externalities such as congestion and pollution. By facilitating a comfortable
and convenient lifestyle, land use planning in Barcelona harks back to
pre-industrial times, whereby people's daily activities were confined to a certain
precinct. As such, residents are able to walk short distances to work or the
shops, and are content in doing so.
Week 12.1 - Earth Hour
Earth Hour is a worldwide movement which involves a multitude of cities turning off their lights for one hour on a specified night of the year. This concept was initiated in Sydney, 2007, and is designed to draw attention to the issue of sustainability and cities. For those who participate, Earth Hour acts as a medium in which they are able to acknowledge their commitment to this responsibility, whilst raising funds for environmental projects.
In terms of acting upon the need to foster a greater interaction between sustainability and cities, Earth Hour can be said to be little more than a symbolic gesture. This concept is still largely in its infancy, so it is a start. The intentions are there, and this movement does raise awareness for ecological initiatives that need immediate attention. In Australia this year's event focused on implementing policies to protect the Great Barrier Reef, a national treasure under immediate threat from climate change. however, as it is essentially one hour of action per year, Earth Hour is vulnerable to ridicule. Commenting on the event, Danish political scientist Dr Bjorn Lomborg argues that it does little to address the primary concern of global warming.
"While more than a billion people across the globe make a symbol of foregoing non-essential electrical power for one hour a year, another 1.3 billion people across the developing world will continue to live without electricity as they do every other night of the year."

Week 11.3 - Reed bed system
Consisting of plants, sand and gravel, a reed bed is an
organic system which is able to reduce the amount of energy used to treat waste.
When waste water is fed into the system, it is treated by microorganisms living
in the roots of the plants, a process which takes approximately 7 days. As a
result, the treated water is able to be recycled and used primarily for grey
water purposes, and depending on the system, the quality occasionally high
enough for drinking. Although a rarity amongst urban environments, reed beds
offer an alternate to the process which often sees Sydney's treated waste water
pumped out to sea. However, it is the implementation of such systems within an
urban environment that is an issue which remains. With space at a premium, roof
tops appear as the obvious option, however the viability of pumping waste water
to them may be disproved through a cost benefit analysis.
Week 11.2 - Farmers
The degree to which a city can be considered sustainable is
not restricted to the inner workings of a city itself. Rather, it is similarly
dependent upon supply mechanisms, e.g. a viable farming economy, necessary to
ensure that produce is able to be provided in a sustainable manner. Due to the
fact that Australia is a nation of droughts and flooding rains, it is essential
that our farmers are provided support during these periods, e.g. through
stimulation packages, in order for them to remain viable and service our
cities. Even though the Australian farming industry is not solely responsible
for supplying our cities, the other alternate, importation, is far less
sustainable considering Australia's geographical context. As a consequence, after two flood years,
followed by record low droughts, the importance of farmers loans cannot be
stated highly enough.

Week 11.1 - Clean Coal
The utilisation of clean coal technology, and the degree to
which it is effective, is an issue which is subject to debate. From an
Australian perspective, the sustainable management of coal is of particular
importance considering that it is the nation's secound largest export with its
industry employing almost 200,000 people and worth $60 billion to the economy.
With the notion of sustainability becoming increasingly relevant to corporate
business practice, Australian companies need to do more to secure their future
as large coal exporters. Neglect of bigger picture issues is driven by
economics, with the preoccupation of their bottom line potentially detrimental
to the long term viability of the industry at large. In comparison, solar and
wind-powered generation have grown more rapidly in response to incentives and
renewable energy targets. Consequently, it is up to the government to take a
leadership role in this matter and implement policies concerning carbon capture
and storage at coal-fired power stations. A look to the London based IEA Clean
Coal Centre is able to reveal that such mechanisms are effective on a
commercial scale.

expert. The Australian Financial Review,

Week 10 - Government Policy
On Monday 31st March, 2014, the United Nations
Intergovernmental Panel of Climate Change released a report detailing the
likelihood of severe and irreversible damage if high greenhouse gas emissions
continue and the planet warms. In Australia, opinion remains divided upon how
to best tackle this issue, with the Liberal government's direct action policy
superseding that of Labour's emission trading scheme. Increasing the cost of
living, specifically gas and electricity prices, the 'carbon tax' was scrapped
on the premise that it placed too great a strain on the Australian economy. On
the converse, the 'direct action policy' aims to reduce emissions by providing
financial incentives to the nation's leading polluters to do so, in accordance
with the implementation of green projects, e.g. the exploration of soil carbon
technologies and abatement.
Both schemes can be classified as polar opposites, and, as a
result, the most appropriate solution to ensure a healthy integration between
sustainability and cities probably lies somewhere in between. Advocates for the
carbon tax argue that it will result in greater and more immediate reduction in
emissions, and that this mechanism is the only viable solution to ensure that
Australia matches the ambition of other countries, who plan a 19% cut by 2020
and a reduction of 40-60% by 2030. In saying this, the carbon taxes' ability to
act as a panacea for reduced emissions is unquestioned, however would see that
Australians would pay dearly in lost jobs, and higher prices for electricity,
groceries and goods and services. As a consequence, the economic implications
may prove to be too costly and potentially impact upon the future capacity to
facilitate sustainable initiatives.
On the other hand, the direct action policy is centred on an
'emissions reduction fund' a pool of $2.55 billion of taxpayers' money, from
which some of the nation's biggest polluters will be paid incentives to cut
their greenhouse gases. This is proposed to be done by means of reverse
auction, with firms who submit the lowest bids, the least expensive way to
reduce emissions, to get government subsidies. In comparison to the carbon tax,
the biggest point of difference is target reductions, with the direct action
plan set to reduce emissions by 5% on 2000 levels. When measured against other
advanced nations, this target is hardly ambitious, and criticised by
environmentalists due to the fact that a stable economy is prioritised over
reduced emissions.
As mentioned previously, the ideal solution probably incorporates
aspects of both schemes. In the long term, rewarding the reduction of
emissions, as opposed to simply taxing them, will provide greater incentive to
be sustainable. With the direct action plan, reduced emissions from power
plants are aided by making buildings more energy efficient, planting trees and
storing carbon in soil. By contrast, the ability to implement such mechanisms
under the carbon tax would be questioned due to the economic burden which
taxing emissions itself carries. In addition, the argument that the direct
action plan (in comparison to the carbon tax) is economically inefficient,
doesn't necessarily wash. Even though it requires tax payers money, it does not
cripple pensioners, small businesses, family and industry by taxing all electricity
in the economy and forcing down demand. Of cause for greater concern is the
fact that the direct action plan only targets the nation's 130 biggest
polluters. It neglects to address the issue of the country's other emitters,
and must be careful that proposed cuts aren't underdone by other businesses
increasing emissions. Furthermore, companies which have spent time and money
switching to more efficient methods of production do not benefit.

Week 9.3 - Waste Management
Waste management, or more specifically, reduction, is a key
criterion of sustainable cities. As a consequence, the habit of 'throwing
things away' is one which needs to be addressed, specifically through a greater
understanding of 'where is away?' Although the term is widely used, it cannot
be said that its implications are fully grasped. Due to the fact that there is
no 'away,' a reversal of this physic in necessary to facilitate a move towards
sustainable habits. More often than not, waste goes to landfill, a place where
toxins leak into the soil, water & atmosphere. As these processes come back
to haunt us, and impact on our lives in negative ways, waste is everyone's
problem and therefore everyone's responsibility.
In order to draw attention to this issue, Natalie Coulter
uses the art of window displays to promote activism in waste management. In
effect, this medium is able to appeal to the masses, and is facilitated through
'repurposed' resources diverted from landfill. Furthermore, association's with
large scale corporations are able to increase awareness, with messages such as
'one man's trash is another's treasure' being reinforced to customers and
shareholders. In Australia, these initiatives are particularly relevant, with
each person generating around half a tonne of household waste per year.

Financial Review, 24-27 April. 34.
Week 9.2 - Space Exploration
With the notion of sustainable cities still in its embryonic
stages, and global population growth increasing by 1 billion people every 12
years, it begs the question as to how long our planet will be able to sustain
the needs of humanity. The topic is cause for concern, and as a consequence,
facilitates debate whether exploration and or habitation of other planets is
necessary. Sceptics argue that resource allocation should be focused on
implementing sustainable initiatives here on planet earth, whereas on the
contrary, exponents of space exploration believe that we are fighting a losing
battle, and that a manned mission to Mars is "feasible, affordable and
necessary" if the human race is to survive. Charles Bolden, head of the US
space program, takes the view that if humanity is to survive indefinitely we
need to become a multi-planet species. The debate is extremely open ended,
however Bolden's view is hard to ignore due to the fact that a mission to Mars
would be able to act as a stepping stone to other planets.

24 April. 8.
Week 9.1 - Agglomeration theory
The degree to which a city can be considered sustainable can
measured through economic factors, e.g. the ability to attract educated
workers. Such facets allow the productivity of a city to be maximised, and are
dependent upon appropriate infrastructure, specifically, an efficient public
transport network. This is due to the fact that notions of agglomeration theory
dictate that industries are more productive/ profitable when clustered, and
therefore see that they are inclined to follow trends of consolidation. In
saying this, Sydney's lack of an efficient public transport network is cause
for concern. By preventing processes of consolidation and, in turn,
agglomeration theory, industry growth will be stunted, or alternatively, have
no option but to spread outwards. Subsequently, negative externalities
associated with this process, including, but not limited to the inability to
attract educated workers, are factors which will prove detrimental to the long
term viability of the city at large.

workers. The Sydney Morning Herald, 23 April. 19.

Week 8.3 - Recycled water: Green Square
With over 20
billion litres of Sydney's stormwater flowing out to sea every year, development
within the Green Square precinct is undertaking a conscious effort to implement
water saving initiatives. Apartment
dwellers are notoriously high consumers of drinking water, with one third of what
they use either flushed down the toilet or used in the laundry. In response, stormwater
harvesting will see that recycled
storm water, purified through processes such as ultrafiltration and reverse
osmosis, is used for bathroom and laundry purposes. In facilitating a recycled
water network, savings are real, with a parallel plumbing system able to provide
up to 900 kilolitres (half an Olympic-sized swimming pool) of recycled water
every day. As a consequence, economic costs associated with the implementation
of such systems are able to be justified through reduced water bills and the
knowledge that a conscious effort is being made to live sustainably.
Week 8.2 - Carbon storage
Up until a paradigm shift signals the widespread
introduction of renewable energy resources, carbon emissions will continue to
act as a hindrance towards the facilitation of sustainable cities. Due to the
fact that development of renewable energy resources are still in their
embryonic stages, and resource consumption continues to grow (quintupling over
the last 5 decades), carbon storage initiatives will be necessary to minimise
the inevitable effects of global warming.
Such initiatives themselves are still very much
experimental, with early research pointing towards the fact that they can
largely be considered as site dependent. In the Huon Valley, Tasmania, a 80m
steel tower has been erected amongst a eucalypt forest with the intention of
monitoring fluctuations in the amount of carbon, water and energy between the
land and atmosphere. In accordance with monitoring soil samples, trees and
bugs, scientists hope the data will reveal how and when forests store and
release carbon. In turn, such knowledge will be able to inform decision making
regarding whether it is better, from a carbon storage standpoint, to leave
mature forests untouched or instead harvest and regrow them. Over the past 12
months, the key finding has been that the hotter days, the forests take in much
less carbon then on the cooler days. As a consequence, this in turn dictates
the need to take swift action before global average temperatures rise further.
Denholm, M, 2014. Forest tower finds the answers to carbon
puzzle. The Weekend Australian, 5-6 April. 10.
Week 8.1 - One child policy
Sustainable population levels are a key criterion of
sustainable cities. In response to this facet, for the past three decades,
China has implemented controls in order to mitigate population growth in the
form of their one child per family policy. Substantial fines associated with
exceeding this limit effectively act as a birth control mechanism, and over
this period, it is assumed that the policy has resulted in 400 million fewer
births. However, in regards to sustainability and cities, the degree to which
this measure can be considered effective is questionable.
Over the short term, this is specifically true, with the
ability to have only one child, or two under certain circumstances, leaving
China with a rapidly aging population. As a consequence, the first children
born under this policy have been left with the added burden of caring for the
elderly. Furthermore, substantial fines associated with exceeding the one child
limit often leave families to lie on census data. In urban areas, children are
often listed to other family members, and in rural areas, left out all
together, with the real population expected to be higher than listed. In
addition, the desire to have a boy has also seen that millions of female
foetuses have been aborted, and resulted in an unprecedented man made gender
imbalance.

Week 7.3 - Adaption
With greenhouse emissions showing no signs of slowing down, this
facet espouses the increasing need for adaption to climate change. In Australia
we have the means to quantify and respond to forecasted impacts through the
implementation of additional infrastructure e.g. by increasing the height of levees
to reduce flooding. By contrast, the same cannot be said for places such as the
Maldives. Due to the fact that its highest point is 2m above sea level, in a
century, it will be completely underwater at high tide, illustrating how the
impacts of climate change are not evenly distributed around the world. Furthermore,
over the past decade, flooding has contributed to 6000 deaths per year, with
four of the top ten countries in terms of deaths relative to total population
from the Pacific (Samoa, the Philippines, Fiji and Papua New Guinea). As a
consequence, reducing the vulnerability of such societies to climate impacts is
essential if they are to remain sustainable.

Week 7.2 - Out of sight, out of mind
An issue which threatens to continually hinder the quest for
cities to become more sustainable is the notion of 'out of sight, out of mind.'
Even though cities are the primary contributors to green house gas emissions,
the effects of their actions are felt elsewhere first and often hardest. The
recent IPPC report illustrates the need for a united approach to mitigate the
impacts of climate change. Without immediate action, consequences will be later
exacerbated, and in regards to Australia, these include, but are not limited
to, loss of mountain ecosystems and native species, the decline of fresh water
resources and reduction in agricultural production.
Seemingly disconnected from urban life, aforementioned
facets come back to haunt urban dwellers through the health and economic
impacts of heatwaves, floods and bushfires. Coffee for instance, is a product
expected to suffer by the increase of global temperatures. With forecasts of
between 2-2.5 degrees of warming, changes in rainfall patterns and the spread
of plant diseases and pests, suitable growing land will contract significantly.
This disruption to production will effect processes of supply and demand, and
ultimately increase the price of a latte in inner city cafes.

Week 7.1 - Moral imperative
The Industrial Revolution (1760-1840) signalled a number of
unsustainable processes whose adverse effects are to be felt most strongly
three centuries on. In terms of climate change, global temperatures are
projected to warm by an average of 4 degrees by 2100, and in turn, negatively
impact on population health and social stability. Aforementioned facets dictate
the need to curb emissions, explore renewable energy resources/ carbon store
initiatives, and implement design mechanisms capable of sustainably mitigating
such increases. Economic considerations see that we are inclined to neglect
such initiatives, yet in doing so, we create problems for future generations
that will continue to impede the facilitation of sustainable cities. With
awareness on the issue as strong as ever, our generation have a moral
imperative to reverse the unsustainable practices of our predecessors for the
sake of our offspring. Failure to do so will have dire implications, with
forecasts that people will be unable to work during the hottest parts of the
year, and in turn, potentially cut global productivity by 40% in the warmest
months from 2100 onwards.

health expert. The Sydney Morning Herald, 31 March. 6.
Week 6 - Urban Consolidation: Sydney
Metropolitan planning strategies that pursue a consolidation
agenda do so in order to facilitate a sustainable future. This is due to the
fact that consolidation, as opposed to sprawl, is seen as a panacea for reducing carbon emissions,
protecting biodiversity, increasing the utilisation of public infrastructure,
and enhancing social cohesion. However, through an analysis of the Sydney Metropolitan Strategy (NSWDOP,
2005) and its review, Sydney
Towards 2036 (NSWDOP, 2010), it is evident that urban consolidation
is hard to implement in retrospect. At sites identified for increased
densities, the state government has encountered local resistance, which can be
seen through NIMBY (not in my backyard) protests in established suburban areas
such as Ku-ring-gai.
This resistance is born out of the desire to still live out
the ‘great Australian dream,’ the notion of owning a home
of one’s own on a suburban quarter acre block. Coupled with failed attempts at
consolidation in the past, traditional notions of consolidation e.g. taller
buildings overlooking/ overshadowing smaller ones, have been seen as the
antithesis of this dream, and help to explain why Australian’s, in comparison
to the rest of the world, have been slow to adopt such planning policies.
Relatively speaking, this problem is unique to Australia, as being such a large
continent; everyone feels they are entitled to their own block. A look to
Western Sydney is able to
reveal the spatial articulation of this dream, and illustrate the powerful grip
it still holds over Australians.
As a
consequence, it is the notion of sustainability, now seen as a common ground
for humanity, which will be integral in facilitating the necessary shift
towards consolidation. However, as this paradigm shift is still evolving, this
stipulates the need for consolidation to first and foremost take place in areas
where it can be justified under the guise of gentrification. As seen through
development at Green Square and Wentworth Point, low density areas traditionally
used for industrial purposes meet this criteria. Furthermore, due to the fact
that they are often run down and/ or underutilise, they provide the perfect
circumstance for strategic master planning to facilitate sustainable, utopian
communities.
In light of this, a look to both developments are able to
reveal a common shortcoming in that they are not readily accessible by public
transport. This is particularly worrying, as the degree to which consolidation
can be considered sustainable is directly proportionate to the degree to which
an efficient public transport network can reduce the reliance on private
vehicle ownership, and in turn reduce congestion and carbon emissions. The
notion of transient orientated development (TOD) is often promoted as a panacea
to implement these criteria, and refers to the process of increasing urban
densities around a centralised transport hub. As a consequence, mechanisms
implemented in retrospect are in contradiction to the very nature of TOD, with
both precincts electing to deal with the issue of accessibility in lieu of
population growth. Such propositions are short-sighted, driven by economics and
serve to counteract positive externalities associated with efficient land use
planning within the precincts themselves.

Week 5.3 - Development firms
Driven by the goal to be net positive by 2030, property
development firm Mirvac are beginning to question traditional motifs of
building design. Why does a building have to consume energy, why can't it
produce energy? Why does a building have to consume water, why can't it collect
water? Why can't a building re-use and recycle all of its outflows? A major
competitor, Lend Lease, is taking a similar approach. Their large mixed-use
development building in London's Elephant and Castle area, due for completion
in 2025, aims to do so with net-zero carbon growth. As touched on in the
previous post, such thinking has far reaching benefits that transcend initial
environmental and economic objectives associated with 'being green.'
In the case of the Elephant and Castle Development,
dwellings will be constructed from cross-laminated timber, a sustainably
sourced and highly insulating material. Subsequently, heaters are rendered
surplus to requirements, and the money saved will be used to install plumbing
which will utilize grey water for toilet flushing. Aforementioned facets of
design help to attract tenants by appealing to their moral obligation to be
sustainable. Of even greater benefit, however, is the developments intention to
influence the behaviour of people living in it and using it. It will improve
public transport links, encourage bicycle use, and a rainwater catchment will be
used to maintain a park in the middle of the development, the largest created
in central London for 70 years.

Entry 5.2 - Roles of Organisations
Utilising the same strand of thought as implemented by
Copenhagen, organisations are starting
to realise the tangible benefits associated with sustainability. This is
relevant to the relationship between sustainability and cities, as the inflows
and outflows of large scale organisations largely contribute to the overall urban
metabolism of a city. Due to associated implications, sustainably innovative
organisations are typically more productive, and similarly, more profitable due
to the fact that 'being green' is marketable. In recognition of this facet,
leading organisations are starting to adjust traditional approaches to appeal
to consumer conscious.
As sustainability is widely accepted as a new common ground
for humanity, innovative organisations will seek to be associated with
buildings that impute their core business objectives, linked to sustainability
in some way. In terms of building design, flexibility is an associated facet as
it allows the function of the building to change without requiring additional
embodied energy. So to natural lighting, which, in accordance with flexibility,
produces spaces rich in amenity and ultimately conducive to creating a
harmonious working environment. In sum, as organisations play an integral role
in forming the underlying fabric of a city, by adjusting their corporate
business practice to account for sustainable objectives, this allows the
overall fabric of the city to follow suit.
Week 5.1 - Copenhagen
Worldwide, the political and environmental climate dictates
the moral obligation for humanity to be sustainable. As a consequence, cities
who recognise this facet are the ultimate beneficiaries, and are able to enjoy
rewards which transcend initial ecological concerns. Copenhagen is a case in
point. Due to a transport network which places a heavy emphasis on public
transport and cycling, Copenhagen is on track to become the first carbon
neutral capital city in the world by 2025. This would be an extraordinary feat,
considering they only began to take sustainable action in 2005.
Changes to infrastructure have revolutionised the way
residents commute, as citizens are able to cycle short distances to public
transport networks, hop on and off with their bikes, before continuing on to
their next destination. Due to its efficiency, this method is more popular than
driving a car. By reducing CO2 emissions, this action gives rise to a multitude
of reactions that can be tied back to economic benefits. Cleaner air and
extensive cycle networks leads to improved health, reducing government funding
for public health care. Furthermore, improved health and reduced congestion
leads to increased production which, in turn, provides the funds necessary to
facilitate further sustainable initiatives. In Copenhagen, an example of this
was their initiative to improve their marine environment by cleaning the water
in their harbour. Due to the fact that 'being green' is marketable, such
actions contribute to the process which has seen an increase in tourism and
real estate prices.

Week 4 - Ecological Footprint... Being realistic
For the first time ever, my participation in SUSD0001 has
led me to calculate my ecological footprint. Entering relatively detailed
information on the EPA website, in about 15 minutes it became apparent that if
everyone lived like me, we would need
4.1 planet earths to sustain such a lifestyle. The degree to which I am
conscious of my ecological footprint probably extends to being wary of water
and electricity usage around the house. Sure, any action is better than
nothing, however from calculating my ecological footprint, and then trying to
reduce it, becomes apparent that even the staunchest of eco soldiers would
struggle to live a sustainable existence in an urbanised world.
In short, my
unsustainable lifestyle is characterised by commuting approximately 20km by car
per day, eating meat daily and travelling 20 air hours per year. This lifestyle
is a direct outcome of the westernised/ globalised culture I am immersed in,
whereby such patterns of living are considered the norm. As a consequence it is
likely that I, along with the majority of others, will continue living in an
unsustainable manner until a significant paradigm shift dictates otherwise.
This is due to the fact that once people become accustomed to certain luxury's
they are unlikely to give them up. In experimenting with the ecological
footprint calculator, the most startling realisation is that by giving up meat,
I could reduce my footprint by 42%. However, due to the aforementioned facet, I
am unlikely to do so.
In addition, it is
hard to realistically implement change when associated benefit seems
disproportionate to sacrifice. It is not always the case that by making a major
lifestyle change, e.g. by becoming a vegetarian, that a proportionate reaction
will ensure. By switching my primary mode of transport from car to public
transport, I would only be reducing my ecological footprint by .1 planets. As a
result, the exponential increase in travel time sees that I am not prepared to
make this sacrifice. Similarly, by forgoing the luxury of air travel, I am only
reducing my ecological footprint by .3 planets.
Even if I was to make
a series of major sacrifices to substantially reduce my ecological footprint, I
cannot realistically reduce my way of living to sustainable levels. Furthermore,
It would be hard to commit to making such a sacrifice considering that
individual action is not going to effect the situation at large. People who
endeavour to live a sustainable existence do so with noble intentions, and many
are content with their way of life, but as rates of consumption continue to
increase, it is akin to swimming against the tide. As mentioned previously, any
action is better than none, and on a large scale, small actions can have a big
effect. However, established institution see that large scale sustainable living
is unrealistic in the current urban climate. Paradoxically, people are almost
better off to continue living in their current manner in order to speed up the introduction
of the inevitable paradigm shift that will signal the widespread use of renewable
energy resources. It is only then that sustainable living can be implemented on
a large scale.

Week 3.3 - Land Use Planning
Land use planning is an overarching management strategy
integral to the facilitation of sustainable cities. Regardless of a cities size
or density, the effectiveness of its productivity is directly proportional to
the effectiveness of its planning. Subsequently, in order to effect the physical,
environmental and economic benefits associated with well-planned urban density,
high-quality development needs to take precedence over high quantity.
In the past, building to maximise returns without accounting
for liveability has proven to be detrimental to density. Contributing to urban
sprawl, this process has proved to be counterproductive to allowing people to
move around easily between home and work - one of the most important factors of
good land-use planning. In Sydney, increasing density around railway stations
would go a long way to rectifying this deficiency, reducing car dependency and
more appropriately utilising our fleet of double-decker trains.

Week 3.2 - Renewable Energy
In the near future, the world is due for a quantum shift in
relation to its primary energy resource. The rate of global oil consumption is
unsustainable, and as it is a non-renewable resource, this action, or lack of,
neglects bigger picture issues. A more strategic approach is needed in relation
to investing into renewable resources, even if it is currently less
economically feasible. In Australia, the long term viability of our cities is
dependent upon government initiatives to overhaul traditional systems and
infrastructure in order to utilise the indefinite amounts of sun, wind and wave
energy unique to our massive content. Such decisions require significant
amounts of funding, however delaying action only serves to delay the
inevitable. We shouldn't have to wait until we are forced into action when the
writing is already on the wall. The government will have to 'bite the bullet,'
so to speak, at one point or another, and the early it does so, the greater the
long term benefits.

Week 3.1 - In Retrospect
Amongst my group,
talk has centred around a focus point for our assignment, specifically whether
or not it is possible to implement sustainable mass urban transport
retrospectively. The general consensus was that implementing this proposal in
theory would undoubtedly differ to reality whereby economics and politics would
come into play. The previous post is a prime example of how Sydney will attempt
to implement sustainable mass urban transport retrospectively. At a cost of
$1.6 billion, The Light Rail Network deals with a problematic issue in the
heart of the city, however it is well documented that Sydney's overall transport
issues run much deeper, with various urban demographics subject to slow and
unreliable service. Furthermore, it emphasises the importance of a master plan
for the city at large, as the success of this addition (the degree to which it
is sustainable) is dependent upon how seamlessly it can integrate with existing
and proposed infrastructure.

Week 2.3 - Light Rail Network
News closer to home
centres around the introduction of the CBD and South East Light Rail Network.
Any addition to Sydney's abysmal public transport service is welcome, however
is this infrastructure a stop-gap solution or of long term benefit? The light
rail service will replace a large number of busses who frequent the CBD, freeing
up pedestrian networks and resulting in reduced congestion and carbon
emissions. For the first time, the infrastructure will provide viable public
transport for large crowds attending sporting fixtures at the SCG & SFS. The
service can accommodate 5 times more commuters than a bus, ensuring more
efficient transport within a high-traffic precinct. As a result the project should
prove to be both an environmental and economic success. Time will tell.

Week 2.2 - Increasing Urban Demographic
Currently around
half the worlds population live in urban cities, with that figure expected to
rise by 20% by 2050. Yes this is a worrying figure, but does it need to be? Can
humanity make the necessary adaption's within 35 years so that Co2 emissions
from cities do not disproportionately outweigh those from rural settings? In
established cities, it is optimistic to say they could, however it is realistic
in cases where effective action is already underway, e.g. Copenhagen who have
expectations to be carbon neutral by 2025.
It is apparent that
the key resource in this process is time, as drastic changes cannot be expected
to happen overnight. However, as innovative cities lay the blueprint for
change, this process can only improve as others follow. There is a great deal
of optimism for master-planned cities, e.g. Masdar City, and great scope for
developing cities (under the condition that strict planning conditions are
adhered to). If they are, there is potential for the increasing urban
population to be offset by a decline in per-capita carbon emissions.

Week 2.1 - An Integrated Approach
First entry! Where
to start? This week my research into the intersection of sustainability and
cities has begun through the transport paradigm. Initial research begun through
this paradigm as the driving requirement for the group assignment was to
establish an individual focus point within the intangibly large subject area of
sustainable cities. Through this investigation it soon became apparent that the
intersection of sustainability and cities consists of a variety of overlapping
paradigms that are impossible to analyse independently of one another. As a
consequence, in order to improve cities both sustainably and equitably, an integrated
approach is required whereby the various paradigms of transport, housing and
population growth are considered as a whole and not individually.
