Development in the Baltic Sea Region

The Planetary Shield is Injured
Here it is: our endangered
atmospheric shield
The Cities in the Baltic Sea Region is a
part of the Problem
So What is a Factor Five
Flow City?
Definition 1: Factor 5 City

A factor 5 City has reduced its need for life
support areas to 20% of the present
situation, without compromising with the
citizens’ access to culture, parks, service,
education and work places.
Definition 2 : Flow City

Physical, economic, organisational and
other resources continuously streaming or
being exchanged in a dynamic system
(e.g. a city).
E.g. flows of energy, money, traffic,
laundry and knowledge. Also a light state
of mind – a psychological sense of
Context.
Definition 3: Factor 5 Flow City

FFFC is a semi-quantitative metaphor for
a city with radically less need for physical
life support and with far less cultural,
social and organisational “friction” than
today.
Factor five flow city = 5 x more
efficient than today
Uses only 20% of the fossile fuels of today
 Has only 20% of the nutrient losses
 Reduce transport CO2-exhaust with 80%
 Has a five time longer ”active” coastline
between built and green structues
 Produces the same social, organisational
and cultural resources with only a fifth of
the ecosystems life support area.

Is this a Good Example?
I was just kidding….
There are good FFFC house level examples
– The Lindås house without Heat System
FFFC communities – Hågaby
model area: 50 aspects of SD.
There are also good FFFC plans
for townscape areas

Looks good, doesn’t it?
Simultaneously……
Life-Support areas (LSA) are too large
Carl Folke et al. 1997. AMBIO
The ratio between City and LSA
City – Life-support-Area
City-Primary Production: 1:200
City-Waste Assimilation area 1:550-1200
City- Total Life-Support Area ~ 1: 1000
The Goal is: 1:200 = Factor 5
Or expressed as footprints: 29 largest BSR
cities appropriate 75-150% of the Baltic Sea

Conserve physical resources and introduce
renewable energy, materials and waters
Decouple economy from environmental impact
Fractally integrate green and built structures
Forms an organisationally efficient city, town,
community and settlement structure
Upholds strong social communities supporting a
sustainable and healthy lifestyle
Always emphasises its local cultures over time
Designs intersensory supportive human habitats
Conserve physical resources:
energy, materials and waters

CONCLUSIONS: The Factor
Five flow City:
Decouples Economic Growth from
Environmental Impact – the Factor 5 Car
(energy and materials)
Fractally integrate built and Green
structures…
…Utilises the Green-Blue City Coast =
factor 5 longer than a compact circle
Forms an efficient communities-, transport-,
and information-infrastructure = factor 5
Upholds strong communities supporting a
sustainable and healthy factor 5 lifestyle
Always emphasises its local
Heritage over time, which
contributes to a Factor 5 lifestyle
Designs intersensory supportive human
habitats = supports factor 5 lifestyle
