Servicing our Cities(Civil) Engineers need to provide
... a source of clean water... energy (gas, electricity ... even fuel)... telecommunications... removal of wastewater (sewage)... removal of storm water (drainage)... removal of solid waste... street lighting
... a variety of means to move around (walking, cycling, cars, trams, buses, trains, rollerblades, pushchairs)
... and yet ‘resources’ extends to food, raw materials, manufactured goods and products, ... while taking advantage of ecosystem services and new technologies

How do we plan, design and construct for the future?... the big debate is about sustainability, or resilience
Sustainability is about putting in place now solutions that will yield a positive rather than negative future legacy
... and we are investing our limited resources today
... we want to make sure they are good investmentsThe essential underlying question is:
“how sustainable are these engineering solutions?” while the answer inevitably is: “it depends on how the future develops”
Resilience is about maintenance of function or service in the face of change ... or bouncebackability in the face of shocks

Vision
Vision: —To test the resilience of actions being taken today (today’s
‘solutions’) in the name of sustainability
Method:— Identifies a sustainability solution and its intended benefit(s)— Identifies the necessary conditions for each benefit to be
delivered … and ensures that they are in place today—Assesses the necessary conditions in four futures:
… will the necessary conditions remain in place?

— In this scenario, powerful actors organise themselves into alliances in an effort to safeguard their own interests
— The UK divides into two groups: an authoritarian elite who live in interconnected, protected enclaves (‘gated communities’) controlling access to resources, and an impoverished majority outside

— In this scenario, current demographic, economic, environmental, and technological trends unfold without major surprise, with convergence toward today’s structures
— Competitive, open markets drive UK development. The self-correcting logic of the market is expected to cope with problems as they arise
— Sustainability issues are addressed more through rhetoric than action
— Materialism and individualism spread as core human values, whereas social and environmental concerns are secondary

— In this scenario, co-ordinated government action is initiated to reduce poverty and social conflict while enhancing environmental sustainability
— Strong government policies and some changes in consumer behaviour emerge to support environmental and social consciousness. Such policies help to negate trends toward high distributional inequity.
— Tensions still exist between the continued dominance of conventional ideologies and values and key sustainability goals
Policy reform

— In this scenario, new socio-economic arrangements and fundamental alterations in societal values result in changes to the character of UK urban civilisation
— The notion of progress evolves and a deeper basis for human happiness and fulfilment is sought
— An ethos of ‘one planet living’ pervades, facilitating a shared vision for a more sustained quality of life, now and in the future

So we have some answer to: “how sustainable are these engineering solutions?” and its blocking answer:“it depends on how the future develops”
Yet the greatest value is in thinking about the intended benefits of our engineering solutions and the conditions necessary for their delivery

Thinking about the Future
To identify and test radical engineering interventions that will lead to low carbon, resource secure future cities in which societal wellbeing is prioritised.
This will be achieved by - envisioning 80%-reduced-carbon resource-secure cities, - working back from there to explore what’s
stopping us getting there, - creating the necessary engineering solutions,
and - proving the concept of a viable and socially
acceptable alternative future.

Why Worry About Resources?
We consume at a greater rate than the planet can supplyThe supply infrastructure is wearing out – material degradationClimate change is changing the environmental context
... and thus environmental stresses on the systemThe demands are changing – population growth, urbanisationExpectations are changing – we no longer tolerate disruptionsPolicy makers tend to take a short-term view – 4-5 years?There are interdependencies – if one service fails, a ‘co-located other’ might be fatally compromisedNational plans often don’t work well in a local context
... ‘local’ is where the services are delivered

Sustainable Engineering Solutions
Locally-sourced water (rainwater harvesting, groundwater abstraction), backed up with mains supplies
Local energy generation, from different sources and backed up by access to the grid
Local food sourcing backed up with sources from afar
Changed usage (consumption) patterns smoothing out the demand
Maximising ecosystem service provision also reduces demand
Local manufacturing paradigms – 3D printing a game changer?
