Adapting to changing climate risk by local government in New Zealand: institutional practice barriers and enablers

Adaptation to climate change has been reviewed in several developed nations, but in none where consideration of the effects of climate change is required by statute and devolved to local government. We examine the role of institutional arrangements, the players operating under them, the barriers and enablers for adaptation decision-making in the developed nation of New Zealand. We examine how the roles and responsibilities between national, regional and local governments influence the ability of local government to deliver long-term flexible responses to changing climate risk. We found that the disciplinary practices of law, engineering and planning, within legal frameworks, result in the use of static mechanisms which create inflexible responses to changing risk. Several enablers are identified that could create greater integration between the different scales of government, including better use of national policy instruments, shared professional experience, standardised information collection and risk assessment methods that address uncertainties. The framing of climate risk as dynamic and changing that differentiates activities over their lifetime, development of mechanisms to fund transitions towards transformational change, are identified as necessary conditions for delivering flexible responses over time.

Integrating the effects of flood experience on risk perception with responses to changing climate risk

Flood management decision-makers face significant challenges as the climate changes. The perceptions of those affected by floods are critical to the successful implementation of adaptation responses; risk perceptions are affected by how information is communicated and, in turn, perceptions influence expectations on flood risk managers to respond. The links between flood experience, risk perception, and responses by individual households were examined in the Hutt Valley, New Zealand, through a household survey, a workshop and interviews with local government practitioners. Two propositions were tested: (1) that flood experience can influence flood risk perceptions; and (2) that flood experience can stimulate increased risk reduction and adaptation actions where changing climate risk is likely. Perceptions of responsibility for flood management were also examined. The study found that previous flood experience contributes to heightened perception of risk, increased preparedness of households, greater willingness to make household-level changes, greater communication with councils, and more advocacy for spatial planning to complement existing structural protection. Flood-affected households had a stronger preference for central government and communities having flood risk responsibilities, in addition to local government. Those who lacked experience were more likely to be normalised to their prior benign experiences and thus optimistic about flood consequences. These results suggest that harnessing positive aspects of experience and communication of changing risk through engagement strategies could help shift the focus from citizens’ expectation that governments will always provide protection, to a citizen–local government–central government dialogue about the changing character of flood risk and its implications, and build a ‘risk conscious’ society in which ‘sharing and bearing’ is considered desirable.

Dealing with changing risks: a New Zealand perspective on climate change adaptation

Future changes in New Zealand’s climate are expected to be less than in many other countries, and New Zealand has well-established governance structures for dealing with environmental risks. While this might imply that adaptation would be straightforward, extensive public and private investments, as well as many traditional Māori assets and cultural values, are in areas increasingly at risk of flooding and sea level rise. In order to consider the country’s adaptive capacity in more detail, we have used an empirical research approach, working with government practitioners at three levels and with Māori communities. Very different perceptions of risk, and structural inertia in planning processes have emerged as key issues for implementing adaptation responses. In particular, the use of static frameworks biases responses towards retrospective, rather than anticipatory analysis. Ongoing socioeconomic changes in New Zealand also raise the risk of structural effects caused by climate change impacts becoming unevenly distributed across society. Our analysis indicates that a national and regional strategic approach, centred on a dynamic view of climate risk, is necessary for effective decisions at the local government and community level. In addition, effective adaptation requires better identification of barriers and opportunities for addressing changing risk, together with more effective and continuous social engagement.

Comment on “From Data to Decisions: Processing Information, Biases, and Beliefs for Improved Management of Natural Resources and Environments” by Glynn et al.

Glynn et al. (2017, https://doi.org/10.1002/2016EF000487) note the importance of engaging stakeholders in the process of public policymaking and analysis. In particular, they highlight the central role biases, beliefs, heuristics, and values play in such engagement. However, the framework they propose neglects uncertainty, which significantly restricts any ability to engage effectively with BBHV. We show how their papers narrow view can be widened to include aspects of risk and uncertainty.
