The need for new competences:
Urban Planning and Management, Sustainable Cities Techno-antroplogy, Sustainable Design
“The complexity and challenges of sustainable development call for new understandings of the socio-technical and economic dynamics
involved and for experimenting with alternative courses of action.”

Cities matters!
And citites are …
• small as well as BIG
• part of something BIGGER – the urban and the rual are closely related

Metropolis for people
COPENHAGEN HAS A VISION
We want to be the worlds best city to live in
A sustainable city with urban spaces, which invites to a multiple and unique urban life
We want to be a metropolis for people
[Københavns Kommune 2009]
Anebjerg
– a new and sustainable urban neighbourhood
the overall goal is an urban quality based development
- characterised by health, sustainability, nature experiences, and environmental protection.
[Skanderborg Kommune]
Not just
Urban space
also
Urban life
Biophilic city – mixing people, animals and plants
The role of plants and animals in the city
Integrating large and small green and blue infrastructures
- More and more diversified nature
- Corridors and space for a range of different animals - A healthier environment - Interesting experiences - More friendly people ;-)

Recilient cities with adaptive capacity
The capacity to handle change and reorganise
… and taking challenges as potentials for development and gains
• Developing more flexible, diversified infrastructures
• Enabling different knowledge and learning to come into play

Urban water transitions?
Water – technology – society
Water supply
city Sewered
city
Water ways city Drained
city Water cycle
city Water sensitive city
Brown, Keath and Wong (2009). Water Science & Technology 59 (5), 847-855 Denmark
Water supply & sewered cities
Water systems part of modernity:
• Effective provision – safe and secure
• ‘Invisible’ disposal of waste water
• New technologies & urban networks
• Regulation and organisations Drivers:
- Health and hygiene - Science, Engineers - Progress and growth

Our drained city
- Post war (1864) + Post war boom (1945): the family dream of house, garden and car - New technologies and push of urban hydrology – to take the storm water of the city - Nature views – rational vs. romantic
- New challenges because of climate changes … and urban renewing

Water ways city
• Challenging the progression of the service delivery that have led to over extraction and pollution
• Working with the ways of water
Denmark - Ecological Modernisation
• Regulation and new technologies – e,g. waste water cleaning,
• Water becoming included in planning as a recreational value
• New professional disciplines
e.g. environmental engineers

Examples
Water Cycle city
• Response to water resource challenges and environmental problems
• Focusing on the water cycles – and nutrients – at different scales
• Saving, keeping and using different water qualities
Denmark:
- Wand plans …
- Water savings – and water balances - Urban gardening …
Examples?
Stenløse Syd Lokal afledning og genbrug af regnvandSilkeborg – faunapassage
Water sensitive city
• Environmental protection and repair
• Supply security and flood control
• Health, recreation values, liveability, economic sustainability
Taking water as a resource Being part of the nature
Technologies, infrastructure and urban form would be diverse and flexible … designed to reinforce sustainable practises and social capital … And be adaptive and continunally evolving …
Examples ?
Examples?
St at us
• Climate adaption on the agenda among water professionals …
• New networks and courses …
• A growing number of projects:
– Separation of storm water – Local handling of storm water
– Greening and visible water elements
• Urban scale – Ørestad, Skt. Kjelds, Greve, Middelfart …
• Municipal climate adaptation plans with risk maps …
• Plans and visions being developed …
… we are ready to go further …

The next steps
1. Up scaling
2. Water as a
resource 3. Integration
4. Strategic urban development
Up scaling
From projects to larger scales:
Working with grey, green, and blue structures:
• At urban level
• Across city and landscape
• Regional
Water as a ressource
From water as a problem to be controlled to Working with water
• Water cycles
• Seasonal changes
• Supporting nature
• Water qualities for health
• Recreative values
Integrative approaches
From a discipline for water professionals to
Working with more perspectives and disciplines - Water in urban development
- integration in other spheres: e.g. urban life, health, social, culture, learning
- Inviting these disciplines in to climate change
- Collaborating with citizens and users
Strategic planning
From infrastructure to Strategic urban planning
• Water in cities
• Water as a major perspective
• Integrations in other plans
