Making Cities and Regions More Resilient

There is growing international interest in the idea of resilience, particularly in Europe. Last year I used the concept in writing the First ESPON 2013 Synthesis Report. This argued that “While competitiveness remains vitally important, new concepts are emerging: energy security, adaptation to climate change, regional resilience and capacity to bounce back.” Leading academics debated “The Resilient Region” in a special issue of the Cambridge Journal of Regions, Economy and Society in May of last year. Then this week I received a copy of the German Annual of Spatial Research and Policy, 2010, which has as its title “Urban Regional Resilience: How do cities and regions deal with change?” Practitioners often find the writings of academics other worldly: however, the annual is a refreshing little book which shows how “resilience” can be interpreted and applied. The Annual also illustrates how research and practice in Germany is tackling climate change and the challenges of “shrinking cities”.

What does it mean?

Like other important ideas, such as “sustainable development” or “territorial cohesion”, there is some ambiguity about just what “resilience” means. This is not necessarily a bad thing. Fuzziness and debate can create innovation. Much of the argument is about whether a concept from environmental science can be extended to encompass social and economic situations. The basic idea is that a system can return to an equilibrium state after a disturbance. Resilience is about the ability to absorb change. Use of “resilience” as a way of thinking can help in managing and reducing the risk that places face from natural hazards or climate change. The UN International Strategy for Disaster Reduction has led the way on this. It’s a pity then that the UK is cutting its funding to this body, as I argued in a recent blog. Through design and planning it is possible to reduce the vulnerability of buildings and places to identifiable hazard events such as floods, heat waves, hurricanes, earthquakes etc. The photo above illustrates only too well how floods, for example, can disrupt a busy city centre, causing economic as well as physical and social damage.

In their chapter in the German Annual, Thomas Naumann and his colleagues, explain how to do vulnerability analysis with particular reference to flood risks. This involves following a sequence that goes “Source – Pathway – Receptor – Consequence”. The findings then inform the design of mitigation measures, so that, for example, when buildings are flooded they can be reoccupied quickly and at low cost. Urban and Regional Resilience

So far, so good, but can we apply the resilience concept to cities and regions, and particularly to the place-based aspects of the management of social and economic risks? The US-based Center for Resilient Cities certainly thinks so. Another US body, the Building Resilient Regions Network concurs. It poses four questions:

• How well can and does the region assess its vulnerabilities to disturbances and its capacity for responding to them?

• How well can and does the region ready itself to respond to assessments and potential disturbances?

• How effectively, in absolute and relative terms, does the region respond to actual disturbances?

• How effectively, in absolute and relative terms, does the region recover from the disturbance and learn from its lessons and insights?

Others working in this area include the Stockholm Resilience Centre and the Association of European Schools of Planning’s group on “Resilience and Risk Mitigation Strategies”. Research in the USA has found that a number of older industrial cities have weathered the economic crisis surprisingly well. Their resilience seems to be explained by their diversified economies, including small advanced manufacturing industries as well as educational and health institutions. Furthermore, precisely because they were rather unattractive to speculative housing development, they managed to avoid the kind of property crash that so damaged “consumption belt cities”.

Resilience and Energy Security

One of the examples given in the German Annual shows how integration of energy issues into urban planning can created greater resilience in the face of energy shocks. It points to a study carried out by the German Ministry of Transport, Building and Urban Affairs (BMBVS) into the use of urban open space to generate renewable energy. It argues that there is untapped energy potential in brownfield sites, conversion sites, vacant lots and land held in reserve. Thus large vacant sites can have a temporary use as short-rotation plantations, or be a place for photovoltaic installations.

Gelsenkirchen shows how an integrated approach can be made to work. Even in this densely populated city in the Rhur, land could be found and turned into a location for energy generation. This leads Fabian Dosch and Lars Porsche to conclude that “The use of renewable energies in built environments requires a new mindset”. They say that “the use of renewable energy will lead to a changed cityscape”. The challenge is to match up energy concepts with urban development concepts. Dosch and Porsche say that there is a great opportunity to capitalise on synergies between urban planning and economic, social and ecological demands. They contend that there is no alternative to a compact and dense city, and that dealing with the spatial aspects should be an obligatory part of all renewable energy funding measures.

Planning to make places more resilient

The German Annual gives a fair picture of where we currently stand in translating the resilience concepts into a set of practical planning actions. It shows that the idea supports innovative interventions in fields like urban energy generation or flood management. However, the underlying prescriptions remain underdeveloped. Diversity and redundancy in network provision seem preferable to reliance on single large spatial concentrations or network connections. As one chapter in the book demonstrates, the idea of resilience is rooted in complexity theory. This provides a useful reminder of how one small and distant event can trigger widespread damage elsewhere. But just to argue that everything is massively complex does not help practitioners much. Perhaps the main message for practice is about the importance of learning and adaptation. Dialogues between research and practice are needed, backed by a willingness to innovate, experiment and share the lessons. The Germans are doing this: others should be.

The German Annual of Spatial Research and Policy 2010 is edited by Bernhard Muller and is published by Springer.
