Publishing relations in our institute

•05/07/2016 • Leave a Comment

A while ago I got hold of a list of current publications of employees in our section and institute (IGN). The network graph below shows how persons are connected by co-authored publications. You can also look at the results here.


Each circle represents one IGN staff member, who had at least one publication in 2014-2015, co-authored with another IGN staff member. Authors are coloured by section or research group (only section of Landscape Architecture and Planning).

Line connections represent co-authored publications. The thickness of the line represents the number of co-authored publications, weighted by the total number of authors of each publication.

All types of publications registered in the Copenhagen University Research Information System (CURIS) included. The graph does only show relationships between IGN staff members. It does not illustrate or include

  • the total number of publications
  • the quality or type of publications
  • publications with a single author
  • publications co-authored with external persons only
  • staff members who have no IGN co-authored publication

Analysis and graphics were done with Excel and Gephi 0.8.2.


Sweden still raising the bar – contribution to JPI Urban Europe by country

•21/12/2015 • 1 Comment

@JPIUrbanEurope has just launched its fourth call, the ERA-NET Cofund Smart Urban Futures Call (ENSUF). In a Joint Programme Initiatives (JPIs) several European countries go together to coordinate research. Since 2012 four calls have been launched through this particular JPI, with changing participation in terms of countries as well as contribution in Euros.

The following two graphs show the contribution to the four calls by country. The first graph shows the absolute contribution in million Euros. The second is a relative index, showing the contribution as share of the countries GDP in PPS (Purchasing Power Standards, Data from Eurostat).


Sweden leads both graphs and has also had an impressively stable and high contribution through all four calls. In the most recent call ENSUF, Cyprus is making the highes contribution compared to its economy. A handful of other countries, including Austria, Finland, Belgium, Norway or the Netherlands, contributed in several calls, while 11 EU member states have never participated in the initiative. On the other hand, JPI Urban Europe goes beyond the EU with the participation of Norway, Switzerland and Turkey in one or more calls.

ps: Actually I am more interested in the call topics, but I got curious about the countries’ shares. Denmark has had varying contributions and I was wondering how this compares to other countries.

Mapping municipal cooperation in Denmark

•21/10/2015 • Leave a Comment

In a previous post I wrote about relations illustrating functional regions, besides commuting, with the example of freight transport. The map below shows networks and cooperations between municipalities in Denmark. The data was collected by the Danish Town Planning Institute, prior to the latest Town Planner meeting focusing on the regional city in October this year.

municipal cooperation in Denmark

The lines show the number of cooperations between the 98 municipalities in Denmark. Only cooperations which were called “important” by at least one respondent were included. The data is based on a survey with about half of the municipalities, which means that some cooperations might not have been mentioned often or not at all. Also, for this map, no differentiation regarding the content of the cooperation was done. Topics included business development, infrastructure, tourism, branding or energy.

Still, the map shows some interesting relations, which also represent functional relations to a certain extend. The whole of Central Jutland is very strongly cooperating, which seems to be driven by the Region of Central Jutland. Another strong network have the western surburbs of Copenhagen, while the municipality of Copenhagen itself is participating in fewer cooperations. There are also other networks visible as in Northeastern Zealand, and Southern Funen.

Even if this particular data is disputable, the map shows that there are other important functional relations between municipalities besides commuting. Other relations in terms of transport (as for recreation, shopping, eduction, social reasons or also goods transport), as well as relations regarding the exchange of knowledge and ideas (as these municipal networks, but also business relations or civil networks) contribute to our understanding and experience of the functional (urban) area.

Small towns restructuring – new findings from Denmark

•04/08/2015 • 1 Comment

We just got published an article on the restructuring of small towns in Denmark.

Small towns are often considered as losing out in the current trend towards urban development. However, research from around Europe shows a great diversity of small town development, including successful development trajectories despite geographical disadvantages.

Population change per city size class, Denmark
Small towns with 1,000 – 5,000  inhabitants grew (on average) more than larger towns from the next size class and considerably more than smaller settlements or the rural countryside, which lost population in the period 2008-2013.

In the paper we examine how the restructuring of retail and service sectors, demographic composition, residential migration, social organisation and community engagement form and affect small town development patterns and specific place-based endowments. Our findings show how favourable development paths are a combination of a positive development in population, provision of daily commodities and attractive housing, and a high number of local voluntary social organisations. Introducing the concept of ‘residential urbanism’, the paper discusses the extent to which a residentially driven urban development can compensate for the generally unfavourable regional development context.

Special issue – Call for papers: Planning for Resource Efficient Cities

•03/06/2015 • Leave a Comment

I am happy to announce a call for papers for a Special issue called “Planning for Resource Efficient Cities” in the Journal of Settlements and Spatial Planning. The Special Issue will be guest edited by my colleague Niels Boje Groth and myself.

  • The deadline for abstracts is 15 July 2015.
  • Invited contributions have to submit the full paper by 15 November 2015.
  • Publication is planned for February 2016.

The Journal of Settlements and Spatial Planning (JSSP) was established in 2010 and is a biannual, peer-reviewed, open access journal, edited by the Centre for Research on Settlements and Urbanism, Faculty of Geography, Babeş-Bolyai University, Cluj-Napoca, Romania. Very recently it got accepted for indexation in Elsevier’s SCOPUS.

We hope to receive contributions from partners of the EU FP7 project PLEEC, but the call is open to other research as well!

Themes for submissions to the special issue can be, but are not limited to:

  • Sustainable urban development
  • Energy and resource planning in cities
  • Urban structure and energy systems
  • Transport planning and energy
  • Retrofitting of the built environment
  • Urban energy production and consumption
  • Sustainable transition and governance of energy and resource use
  • Multi-level energy planning and policies
  • Rebound effects and trade-offs in resource efficient cities

Still decoupling? GDP, energy use and CO2 emmissions in Denmark

•17/03/2015 • 2 Comments

[the post was updated with corrected data, see comments]

In a report from 2004, the Danish Ministry of the Environment published a graph illustrating the decoupling of economic growth from energy use and CO2 emissions. The graph shows that (after a restructuring phase in the beginning of the 1980s), GDP was increasing continuously since while energy use was stable and CO2 emissions even dropping since 1991. So the Danish economy was actually effectively decoupling from energy use and emissions.

I was wondering how the most current development looks like and if Denmark is still following this trend. After having some trouble with the data*, I finally managed to produce a current version. I used 1990 as an index as this is also the year Kyoto is refering to. Looking at the last decade we can see that energy use was slightly increasing until the ecomonic crisis and is since dropping and today back at the level of 1975. CO2 emissions have continued to drop which shows a real decoupling of the Danish economy from CO2 emissions.

It seems like investments in energy efficiency and renewable and CO2-neutral energy are making real progress. However, other factors like the outsourcing of CO2-emmitting and energy-intensive economic activities might also play a role. A footprint analysis could give clarity in that case.

* One data issue is, that emissions from international transport are not included the Kyoto-CO2 emissions target. However, while inland CO2 emissions were decreasing, CO2 emissions caused by e.g. Danish operated ships abroad was increasing heavily, and actually outpacing the inland reduction. So if this would be included in the CO2 balance, Denmark would actually have a strongly increasing CO2 emissions, increasing similarly to GDP.

The 1979-renewal plan for Nørrebro, which provoked violent riots in Copenhagen

•07/01/2015 • 1 Comment

As written in a previous post, I digitized the well-known Copenhagen Finger Plan from 1947. During my recent teaching activities I borrowed some more ‘classic’ planning documents from Denmark and digitzed parts of it. The first one is the 1979-Masterplan for the Copenhagen district of Nørrebro (Helhedsplan for Indre Nørrebro). The document confirmed the polarizing planned renewal of the district, which topped in violent local riots (‘Kampen om Byggeren‘) in spring 1980. On pages 14/15 you can see a proposal for the radical reduction of the built environment including the demolition of more or less all existing buildings of that time. Although it is highlighted that the proposal is only hypothetical, it is comprehensible that it has provoked many. Following the experiences from Nørrebro, urban renewal changed in Denmark towards a more inclusive approach focusing on renovation rather than on demolition, which could be seen in the following renewal of Vesterbro.
