METHODSEvaluating flood risk management options in Scotland: A participant-led multi-criteria approach
Introduction
In Scotland the estimated annual average damage attributable to inland flooding is £185 million (Werrity and Chatterton, 2004) and if the effects of climate change proceed as predicted this is likely to increase. The potential costs of flooding together with EU legislation in the form of the Water Framework Directive and the forthcoming Floods Directive have driven renewed interest in flood risk management in Scotland. Part of this interest has focussed on assessing flood risk management techniques, including flood warning, flood water storage (JBA consulting, 2005), and techniques that might be described as sustainable flood management (RSPB, 2004).
In terms of physical characteristics flood risk management is complex, uncertain and involves large temporal and spatial scales. In terms of social characteristics it involves conflicting interests between stakeholders, a plurality of legitimate standpoints, and diffuse responsibilities and impacts. Van den Hove (2000) and Proctor and Drechsler (2006) argue that natural resource problems that display such characteristics require the use of participatory approaches for proper assessment and management. With these characteristics in mind the aim of this study is to develop and test a method to evaluate flood risk management techniques or options using a deliberative, participatory multi-criteria process with members of the public in three regions of Scotland.
The paper is structured as follows. In the next section we critically discuss a number of deliberative methods that have been used to examine natural resource issues, and highlight the pitfalls we hope to avoid and benefits we hope to draw on in developing our method. Building on this review we set out the rationale for and steps of the method developed for this study in Section 3. In Section 4 we discuss implementation of the method before setting out the analysis and results in Section 5. In Section 6 we evaluate and discuss the method before concluding.

Deliberative evaluation processes
In recent years the use of participatory deliberative approaches has proved particularly interesting to those in natural resource management for substantive, instrumental and normative reasons (Fiorino, 1990); substantive, in that more people are brought in to analyse the problem and greater and wider expertise is brought to bear; instrumental, in getting agreement and acceptance of the problem and possible solutions; normative, in terms of building capacity within communities to get involved
Case study areas
The methodology developed was implemented at workshops held at three locations around Scotland in September and October 2005, Inverurie in Aberdeenshire, Callander in Stirling, and Alloa in Clackmannanshire. Table 2 provides some statistics from the local authorities to give a flavour of each, and for Scotland as a whole for comparison. In terms of employment, education and health, Inverurie seems to be the best off area, with Callander second, and finally Alloa. However, in terms of housing
Method design
The method used in this case study was designed to allow public participants to assess a range of different flood risk management options in general terms, drawing on their experiences and on discussions with other participants and experts. The workshops were designed around six multi-criteria steps broadly following the DETR (2001) approach. They are set out in detail below.
Analysis and results
One of the features of the method developed and implemented in this case study is that both qualitative and quantitative data are provided for analysis. In this section, we analyse and provide results from the quantitative data, and offer a richer picture and explanation of the quantitative results with reference to some of the qualitative data obtained.
In all, 69 participants took part in the workshops. Slightly more women than men participated overall, with a good balance between age groups.
Discussion
The discussion will focus on two areas: the findings of the workshop and an evaluation of the method developed and implemented in this study. Overall, the workshop results showed that participants preferred allowing regeneration or planting of native woodland to other flood management options and least preferred building flood walls and embankments. A number of points should be made in relation to this. First, the results must be seen in the context of events that occurred just before and
Conclusion
Conducting participant-led MC workshops to determine preferences for flood risk management options in Scotland provided some notable results: that participants preferred regeneration or planting of native woodland to other flood management options, and least preferred building flood walls and embankments. The design of the workshops allowed a rich dataset to reveal the thinking behind such results and provided a deeper understanding of why participants came to these conclusions.

2023, Omega (United Kingdom)Citation Excerpt :The annual flood damage in Scotland is approximately £252m (56% river flooding, 23% surface water flooding, and 21% coastal flooding) within 2016-2021. This amount can be increased considering the climate change effects as well as challenges to mitigation and adaptation that the country might face in its long-term planning [58,99]. This considerable cost of flooding has sparked interest in flood risk assessment by policy makers, necessitating sophisticated techniques to address long-term strategy selection via informed decisions.

2021, Ecological EconomicsCitation Excerpt :This was partly because it was more time efficient to have a single expert to brief the jurors, drawing on the work of a multi-disciplinary expert group on peatland ecosystem services (see Saarikoski, Mustajoki, Hjerppe, and Aapala, 2019). We also wanted to avoid the risk that the personality of experts might have more influence on people's perceptions than the content of their presentation (see Kenyon, 2007). Three parallel citizen panels with 9–11 participants in each (31 in total) were organised sequentially between April and October 2017.
