Sustainability, no matter what definition is used,
is all about the future - putting in place now interventions
(solutions) to problems that will yield a positive rather than negative
future legacy.

Sustainability and Interventions II
For an intervention to succeed, certain necessary conditions must remain
in place
but these conditions are usually only implicitly considered (if at all) in
planning and development.
The continuation of necessary conditions determines the resilience of a
solution.

Question
“how sustainable are
the interventions we
propose?”
Designing Resilient Cities
Answer
“it depends on
what the futures
hold”
![Page 9: Sustainability - the driver of innovation](https://reader034.vdocument.in/reader034/viewer/2022042817/55a977301a28ab760e8b457a/html5/thumbnails/9.jpg)
The Future is plural
Futures thinking exploits the human capacity for change
Urban Futures are
• derived from established philosophical positions: Thomas
Hobbes, JS Mill, Adam Smith, EF Schumacher.
• derived from global scenarios → consistency across scales
Derived urban futures can pressure-test sustainability solutions
Method gives rise to a shared rationale for interventions
can guide practice at every level from policy formulation through to
implementation in specific sites, reducing the risk of “box-ticking”.

How might the future change?
The
population
decreases?
The site is sold
and the new
owner doesn‟t
prioritise reduced
car ownership?
Someone
removes the
roadside
trees?
Live/work
becomes
the
norm?
Shopping
patterns
change?
Government
policy
changes? The city
becomes
more
densely
populated?
There is no budget in five
years to pay for
maintenance?
Residents prefer a
tumble dryer to
hanging their
washing outside?

New Sustainability
Paradigm
An ethos of „one planet
living‟ facilitates a
shared vision for more
sustainable living and a
better quality of life
![Page 14: Sustainability - the driver of innovation](https://reader034.vdocument.in/reader034/viewer/2022042817/55a977301a28ab760e8b457a/html5/thumbnails/14.jpg)
Policy Reform
Comprehensive and
coordinated
government action
towards greater
sustainability is
initiated
![Page 15: Sustainability - the driver of innovation](https://reader034.vdocument.in/reader034/viewer/2022042817/55a977301a28ab760e8b457a/html5/thumbnails/15.jpg)
Market Forces
Well functioning
markets are seen as
the key to resolving
social, economic and
environmental
problems
![Page 16: Sustainability - the driver of innovation](https://reader034.vdocument.in/reader034/viewer/2022042817/55a977301a28ab760e8b457a/html5/thumbnails/16.jpg)
Fortress World
The world is divided,
with the elite in
interconnected,
protected enclaves
and an impoverished
majority outside

interventions made in the name of sustainability

Sustainability and Interventions III
An Intervention must have at least one intended benefit,
but it is often lost in the design or decision chains of planning and
development.
Any solution/intervention can have unintended drawbacks.
Drawbacks are often context-specific, but so too are benefits.

Step 2Necessary Conditions for Success
• Non-potable water demand
• Enough greywater must be
collected
• Enough greywater must be
stored
• Must be economically viable
• Must be acceptable to the
community
• Others?
