Book reviews
http://pacific-edge.info/?p=200
A couple weeks ago, I received a phone call from a woman in the
Department of Prime Minister and Cabinet. She wanted to know if the
Department could use a short piece from something I had written in a
set of guidelines they were producing. The guidelines, she explained,
were for other levels of government and institutions to use when
thinking about how to make communities more resilient. It was then
that it dawned on me just how far this notion of resilient communities
has gone and how broad is the depth of interest in it.
In the community sector, the term
'resilient communities' is heard among those active in the
relatively new Transtions Initiative groups
(www.transitionsydney.org.au). There, it summarises a range of ideas
on how societies can adapt to the synchronous impact of peak oil and
climate change.
Transition Initiatives, however, are far from the only ones using the
term. That was reinforced for me while in Gleebooks one day. There,
while perusing the environment titles shelves, I came across a
paperback, the collective work of three authors: Peter Newman,
professor of sustainability at Curtin University in WA, author of
Cities as Sustainable Ecosystems (2007, Island Press) - Peter Newman
was once the NSW Sustainabilty Commissioner - Timothy Beatley,
professor of Sustainable Communities at the University of Virginia and
author of Green Urbanism Down Under (2008, Island Press); and Heather
Boyer, senior editor at Island Press and Loeb Fellow at the Harvard
Graduate School of Design. None of these are intellectual light
weights and what they say must be taken with more than a grain of
seriousness.
And the book - it was
called Resilient Cities -
responding to peak oil and climate change. http://www.resilientcitiesbook.org/
Necessary reading
This is exactly the sort of book Transition Initiative people and
their fellow travelers, permaculturists, should take the time to read.
The synchronous peak oil-climate change challenge to our resource
intensive cities is analysed, as is the nature of the climatic and
energy threats. After creating a typology of four urban future
scenarios, the authors go on to describe visions and hopes for
sustainable cities. What is good is that there are many examples of
positive responses drawn from Australia
What is also of interest, to
those active in the permaculture and Transition movements, anyway, is
the revelation of how permaculture is perceived by planning and design
professionals working in education and sustainability practice. The
authors certainly take permaculture seriously, however they remain
critical of its approach to an oil-depleted and climatically-altered
future for our cities.
Why this is important is because
these people are influential. They frame thinking about permaculture
and affect how others perceive it. Permaculture, Transitions and
related approaches to sustainable development at the community level
all circulate in the public marketplace for ideas, something that
makes how they are perceived critical to their future
opportunities.
This is revealed in the chapter
describing four scenarios for the future of cities. Drawing up
scenarios is a way of thinking about the future that has now been in
use for decades and has been adopted by a range of organisations in
society, including business. One of its advantages is that it engages
the imagination to envision alternative futures based on current and
likely events and trends, as well as unexpected events, and allows you
to step out along exploratory pathways of the imagination in
considering how things could unfold from different starting conditions
and how they might be responded to.
What becomes clear as you read
the book is that the authors are familiar with the different
scenarios, including those of Richard Heinberg and David Holmgren.
Heinberg, an American, toured with David Holmgren several years ago to
alert Australian audiences to the challenge offered by the peaking of
global oil supplies. The authors have done their research and, to
that, they add their extensive and more than credible knowledge
developed of years of experience.
The four urban scenarios the
authors explore are: collapse, ruralisation, the divided city and the
resilient city. Transition and permaculture interests might wonder why
the ruralised city and the resilient city are treated separately, for
surely they are the same? Hasn't permaculture's Bill Mollison and
David Holmgren painted them as such? Well, it turns out that they are
not the same and that, for the authors, the resilient city is the
preferred future.
Collapse
The collapse scenario is familiar - the synchronous impact of peak
oil and climate change combine to create a descending spiralŠ price
rises for fuels and food hit the less affluent hardestŠ markets
change as household funds are diverted from discretionary spending
into buying increasingly costly basic needs, businesses collapse, jobs
disappear, family and mortgage stress increases, family homelessness
(already a phenomenon in Australia in the current recession) becomes
more common and, as a result of this trend, a climate of fear and
panic descends.
This is likely be be felt more
keenly, the authors say, in the newer, outer ring of suburbs that have
grown up on the assumption of a continuous supply of relatively cheap
vehicle fuel. Out there, car reliance is a basic given, public
transport is not particularly effective at moving people to and from
workplace, commercial centre and shopping mall and walking and cycling
simply are not options due to distance and lack of safe cycling
facilities. These distant suburbs are vulnerable suburbs in a
situation of energy and climate stress.
In a climate of despair, family and
community stress, the fear that sets in starts to manifest as panic.
Opportunities for adaptive responses collapse as the resilience of
civil society goes into freefall. Those who remain in the vulnerable
suburbs live on whatever meagre resources a society tumbling into
recession can provide. Others move on.
We can imagine this. Just as in the
Great Depression of the 1930s, shanty towns and tent cities appear.
And just as in those years, this triggers social resistance by the
more affluent, the employed middle class and environmentalists who
press the authorities to remove the squatter camps from their view and
off of nature reserves and national parks. Quickly, a social fracture
becomes a social chasm.
According to the authors, this is the type of future that stems from
the denial of peak oil and climate change. It is as Thomas Homer Dixon
wrote in The Upside of Down - that it is when resource,
environmental and social stresses combine in synchrounous failure that
social and personal support systems start to fail.
This is a bleak future that has a
certain appeal to the apocalyptic mindset. That mindset is more
prevalent in the US than in Australia and New Zealand, however it is
being talked up here, too, the authors suggest.
Bill Mollison and David Holmgren
(co-originators of the permaculture design concept) and Ted Trained (a
UNSW lecturer who has written extensively on future scenarios and
sustainability) have warned that our present society may find it
difficult to adapt to the potential impact of peak oil and climate
change, especially if their impacts start to be felt at the same
time.
None, however, say that we should
accept collapse in the way that some peak oilers (those who see peak
oil as, primarily, a collapse scenario) do with what the authors say
is their often overstated rhetoric. They say that in Energy Bulletin,
edition 6.6.04, David Holmgren is reported as portraying such a
doomsayer vision of a peak oil future.
The divided city
This model is one unconducive to achieving urban sustainability. It is
of a model the city divided along the lines of social class, with
wealth a determinant of sustainable living.
It was years ago that I first found
this model described in a novel. That book portrayed American society
of what was the near future, a society in which the less affluent
masses lived in socially and environmentally decaying suburbs in which
there was limited opportunity. The wealthier occupied what we would
now call ecovillages - in effect, they were gated communities in
which the residents enjoyed the benefits of renewable energy systems
and other technologies of sustainability, and the security that comes
from having guards on the gates.
We already have gated communities,
the most effective barrier of entry to which is less the guards than
the cost of the real estate. The products of social fear and
exclusivity, they are increasingly criticised by planners. They
sometimes have regulations that in effect become a form of social
control. In this, they have some parallel with some ecovillages in
which aspects of behaviour may be constrained, such as the colours you
can paint your house, how you can make use of your land, what types of
domestic animals you cannot keep, the discouragement of informal,
uninvited visitation to the ecovillage and so on. For the most part,
such restrictions are based on environmental considerations, and while
this is both reasonable and responsible, it is often only one
particular take on people and their environment. Nonetheless, it is
this that distinguishes authentic ecovillages from gated
communities.
The divided city is one in which
this social divide is also an opportunity divide. It is not a model
for sustainable urbanisation.
The ruralised city
Those in permaculture and some in the Transition Initiative movement
will be familiar with the ruralised city model. The scenario goes like
this - as climate change and peak oil make their combined impacts
felt, a demographic and agricultural renaissance takes place in the
suburbs of Australian cities as they are transformed into places where
food, fuelwood and fibre are produced.
This is an evolutionary scenario in
that it takes place over time. It is based on a household-led
renaissance in which suburban houses become multigenerational,
extended family locales amid the new, urban fields of food and fuel.
It is a vision very much along the lines of conventional permaculture
thinking and is even one that people have here and there sought to
give birth to where they have removed fences between adjoining
properties and shared resources. Ted Trainer, in particular, has been
a strong advocate of this vision of the city.
Those instances, few they might be,
where neighbours remove fences and share resources have been
exemplary, however they have proven largely unreplicable, not because
the idea is unworkable but because there has been no broad motivation
and because urban populations are often mobile populations, a
situation in which linking adjoining properties and sharing space is
unlikely to endure.
Elsewhere, the authors acknowledge that urban agriculture is a good
thing, however they agree that David Holmgren's vision of the
rurualised city is a flawed one. Their objections follow.
Urban sprawl
David's model encourages urban
sprawl. Its focus on the detached suburban dwelling would see the
further spread of the suburbs and the further loss of our urban fringe
farmlands, already threatened in Sydney and Melbourne by urban
development (52 percent of Sydney's existing market gardens and
small scale farming enterprises are in the state government's urban
growth areas).
The model thus threatens the resiliency of the cities.
The individualisation of the
problems
A focus on the ruralised city and
the suburban house as the centre of adaptation to peak oil and climate
change individualises both the problem and the solution. The authors
assert that individual, uncoordinated approaches to sustainable living
will not achieve desirable outcomes. What is needed are region-wide
solutions, not just the one-offs that rely on the individual
initiatives of householders. Those exemplary initiatives need to be
scaled-up and made affordable and accessible to
thousands.
Helena Norberg-Hodge, of the
International Society for Ecology and Culture and a leading figure
promoting community-based, urban food systems in the UK, has warned
against the individualisation of responsibility for our environmental
problems and against the placing of responsblity solely upon
householders and individuals. This, she suggests, allows industry,
government and institutions to avoid their share of
responsibility.
Whatsmore, the individualised
approach is socially inequitable, being dependent upon home ownership
and access to sufficient affluence to fund the changes. The continuity
of that affluence into a period marked by economic downturn stemming
from peak oil and climate change must be doubted. I realised that this
really is a factor when friends explained to me that they could not
afford to install solar hot water, although they would have preferred
to. People need funds for discretionary spending, even when government
rebates are available, to install solar water heating, photovotaic
panels and the rest of the energy and water efficiency domestic tech
kit. Maybe this is why we see them in mainly better off, more affluent
suburbs.
The authors say that cities are
collective entitiesŠ that is, they are more than individualised
houses and the nuclear or other family types inhabiting them. Thus,
common solutions are what is needed, rather than the one-off
initiatives of the environmentally committed. This might have been
what social entrepreneur Mitra Aadron was getting at when, some time
ago, he wrote on the Oceania permaculture email discussion list that
sustainability initiatives have been one-off affairs and that a more
innovative approach was called for to scale-up access to the
technologies of sustainability for householders. His solution was the
bulk-buying of the technology of household sustainability.
A bleak future for parts of the
city
The ruralised city model offers a
bleak future for those parts of the city unable to grow food and
fuelwood, harvest and store water and process their wastes
Presumably, this would include the denser, inner urban ring of
urbanisation close to the city centres. Yet, it is just this density
of population that commentators say is needed to make public transport
economically viable, and thus reliable and efficient, and to make
those places into walkable and cyclable suburbs.
This is a critique of the ruralised
city model that has been offered by others. They say it has little to
offer medium density residents at a time when more and more people are
attracted to apartment living or when that is the only type of
dwelling that is affordableŠ such as with first home
buyers.
The sustainable city
This is the authors' preferred model. It is eco-efficient in regard
to energy and water, has effective public transportation that includes
walkable and bicycleable suburbs, viable local economies, produces
much of its own fresh foods - especially in the ecovillages located
in what are presently the newer, outer suburbs vulnerable to peak oil
and climate change, and its infrastructure is carbon
neutral.
If I am allowed to add my bit, I
would say that the sustainable city is also the wired city in which
teleworking and teleconferencing replace a portion of personal,
workplace-related travel. High-speed, affordable bandwidth makes this
possible, as do the technologies of the mobile Internet.
It is also the food city, with urban
fringe market gardens, orchards, poultry farms and mushroomeries
protected by zoning legislation from being overrun by urban
development. Aquaponic installations exist as small businesses within
the suburbs as do community gardens for their food and social
values.
The path
So, how do we avoid the divided city and collapse and get to the
sustainable city?
You will have to read the book for the detail in which the authors
describe ten strategic steps towards sustainability. They include
among these the installation of sustainable infrastructure, the
regeneration of households and neighbourhoods, the facilitation of
localisation and the use of government approvals to regulate for a
post-oil transition.
For those community associations
pursuing the Transition approach to a sustainable future, Resilient
Cities - responding to peak oil and climate change will help to
bring rigour and credibility to their argument. At the same time it
will challenge them, especially in its constructive criticism of David
Holmgren's scenario of suburban adaptation. This might not be
received well in some permaculture circles as self-criticism has never
been a strong feature in permaculture and reaction to outside critical
comment has sometimes been quite defensive rather than
considerate.
Nonetheless, as the Transition
Towns/Transition Initiatives movement makes its presence felt more
keenly in the social marketplace for ideas, criticism will become more
frequent and more pointed. Reading this book in an open frame of mind
will help such groups revisit their core beliefs and ask themselves
questions about their validity.

Half of the world's inhabitants now live in cities. In the next
twenty years, the number of urban dwellers will swell to an estimated
five billion people. With their inefficient transportation systems and
poorly designed buildings, many cities-especially in the United
States-consume enormous quantities of fossil fuels and emit high
levels of greenhouse gases. But our planet is rapidly running out of
the carbon-based fuels that have powered urban growth for centuries
and we seem to be unable to curb our greenhouse gas emissions. Are the
world's cities headed for inevitable collapse?
The authors of this spirited book don't believe that
oblivion is necessarily the destiny of urban areas. Instead, they
believe that intelligent planning and visionary leadership can help
cities meet the impending crises, and look to existing initiatives in
cities around the world. Rather than responding with fear (as a legion
of doomsaying prognosticators have done), they choose hope. First,
they confront the problems, describing where we stand today in our use
of oil and our contribution to climate change. They then present four
possible outcomes for cities: "collapse," "ruralized,"
"divided," and "resilient." In response to their scenarios, they
articulate how a new "sustainable urbanism" could replace
today's "carbon-consuming urbanism." They address in detail how
new transportation systems and buildings can be feasibly developed to
replace our present low efficiency systems. In conclusion, they offer
ten "strategic steps" that any city can take toward greater
sustainability and resilience.
This is not a book filled with "blue sky" theory
(although blue skies will be a welcome result of its recommendations).
Rather, it is packed with practical ideas, some of which are already
working in cities today. It frankly admits that our cities have
problems that will worsen if they are not addressed, but it suggests
that these problems are solvable. And the time to begin solving them
is now.
