WHERE DO THE CITIES’ STRATEGIES FALL ON THE STABILITY LANDSCAPE?

THE RESILIENCE FRAMEWORK KEY TAKE AWAYSAN OVERVIEW OF CLIMATE-PROOFING STRATEGIES ADOPTED ACROSS THE WORLD

Components of Resilience

Latitude:the maximum

amount the system can be

changed before losing its ability

to recover

Resistance: the depth of basin representing the ease or difficulty of changing the

system

Precariousness:the current

trajectory of the system, and how close it currently

is to a limit or “threshold”

Panarchy:the influence ofother scales onthe states and

dynamics of the system

Adaptability:the capacity of

human agents to modify any of the

aspects of resilience

Transformability:to create a

fundamentally new system when the existing systems

becomes untenable

§ The Stability Landscape using a ball-in-bowl metaphor (from Walker et al. 2004).

§ The ball indicates the state of the system and the characteristics of the basin represents the stability and ability to recover from an external shock.

§ Each strategy was viewed as building one or more components ofResilience (Latitude, Resistance, Precariousness or Panarchy).

§ For example, Copenhagen increased the urban blue green areas to absorbmore rainfall and prevent urban flooding. This can be equated toincreasing the width of the stability basin. Thus, this strategy is classifiedas building Latitude.

§ On the other hand, Rotterdam built dykes to withstand the rising sealevel. This can be equated to increasing the depth of the stability basin asit is now harder for the threshold to be breached. Rotterdam’s strategywas thus classified under Resistance.

§ Curbing of carbon emissions falls under the class of Precariousness.§ City of Wuhan transformed its landfills to community gardens. This is an

example of landscape Transformation.

A Resilience Analysis of the C40 Cities

§ Majority of the C40 cities have sought to “reduce carbon emissions” as a ‘climate proofing’ strategy.

§ While this is critical as a long term, global strategy; reducing emissions is insufficient for tackling the short-term variability and mitigating impacts at a city scale

§ OBJECTIVE - To assess the efficacy of the strategies adopted across the world from a resilience perspective

Size of the node represents the number ofstrategies exclusively falling under each ofthe categories. Width of the link representsthe number of cases where a combinationof two were adopted. (schematic)

Paradox of threshold - In a dynamic system the basin characteristics as well as thresholds change stochastically. Thus, adapting to the changing environment is extremely important.

A question of scales - Extreme weather events happen at the city scale, and they are happening NOW. Therefore, they warrant LOCAL and IMMEDIATE solutions – Focus on regional adaptation

Understanding Panarchy - Impact at one scale might be the result of causes at a different scale.
