3 Outline Context European Disasters Ireland Policy shift Bray case study Perceptions of flood risk Preparedness Awareness Responsibility Policy 3

4 Natural Hazards Globally, 3.4b people exposed to one or more natural hazard Increasing number of events? Rising costs? Explained by increased awareness? Climate Change impacts? 4

5 Natural Hazards in Europe saw 928 major events recorded: 99,000 fatalities 148b losses ( 36b insured losses) Including 213 flooding events: 1,100 fatalities 52b losses ( 12b Insured losses) (EM DAT, 2010) 5

6 Ireland Summer Floods 2008 Localised flooding in counties Dublin, Wicklow, Wexford, Offaly, Tipperary, Kilkenny, Laois... Major flooding in Carlow, Newcastle West and Mallow Dublin Newcastle West 6 Carlow

7 Ireland Winter Floods 2009 Parteen Weir, Birdhill Cork Ballinasloe Mallow 7

8 Ireland Total identified costs of 2009 floods was 520.9m: 276.9m related to costs to the State damage to roads, infrastructure, the provision of temporary accommodation, costs incurred by the rescue services. 244m consisting of damage to private infrastructure and covered by private insurance Figures exclude uninsured and non-monetary social costs Importance of communications, preparedness, and emergency planning in response to extreme events: Joint Oireachtas Report (2011) DoECLG Review of the Response to Exceptional Severe Weather Events of (2012) General lack of socio-economic analysis of flooding in Ireland, its impact on people, and people s views on different policy responses. 8

9 Irish Context Ireland is also facing an increased likelihood of environmental hazards due to Climate Change (Sweeney et al., 2008; IPCC, 2007) Risks are likely to increase over time due to climate change (Murphy and Charlton, 2009) 9

10 Policy Responses to Flooding Mitigation: Spread the losses loss shared by wider society through public insurance schemes Plan for losses raise awareness of risk and relief only possible through private insurance Bear the losses individuals and companies bear the losses and cope as best they can. Protection: Modify the risk by reducing the probability of damage Structural solutions Macro protection community-level flood relief schemes Micro protection household level resistance measures Adaptation: Modify the loss potential by reducing the consequences through non-structural means early warning systems, evacuation plans, land use planning, household level resilience measures 10

11 Responses to Flooding Mitigation of losses: Spread the losses loss shared by wider society through public insurance schemes Plan for losses raise awareness of risk with relief only possible through private insurance Bear the losses individuals and companies bear the losses and cope as best they can. Protection: The Traditional Response Modify the risk by reducing the probability of damage through structural solutions Macro protection community-level flood relief schemes Micro protection household-level resistance measures Adaptation: Modify the loss potential by reducing the consequences through non-structural means early warning systems, evacuation plans, land use planning, household level resilience measures 11

Protection: Modify the risk by reducing the probability of damage Structural solutions Macro protection community-level flood relief schemes Micro protection household level resistance measures Adaptation: Modify the loss potential by reducing the consequences through non-structural means: Flood Awareness/Preparedness Early warning systems Emergency (evacuation) plans Land use planning Household-level resilience measures 12

13 New Policies Paradigm More focus on resilience than on prevention with increased attention on flood warnings, public perceptions of flood risk and flood awareness (Wolsink, 2010; Tunstall et al., 2004; Werritty, 2006) Little literature on public engagement, and on perceptions and attitudes to flood risk 13

14 New Policies Paradigm More recently, analysis of spatial patterns of social vulnerability associated with flooding why types of people locate in vulnerable locations, live in inadequate homes and fail to anticipate, resist or recover from the aftermath of an event (Tapsell et al., 2002). examination of place attachment, flood preparedness and evacuation dynamics (Mishra et al., 2010) 14

15 Case Study 15

16 Bray Case Study Bray, located in North East Wicklow and c. 12 miles south of Dublin city centre. Population of c. 27,000 Located on the Dargle River. Coastal location 16

17 Bray: Historic Flooding Four major flood events in Bray during the last century 25th August rd September th and 17th November th and 26th August 1986 less significant floods occurred in Bray in 1947 and Flooding in Bray occurs with an approximate frequency of once every 25 to 30 years Hurricane Charlie return period of between 50 and 100 years in the low lying areas of Bray 17

20 Bray Case Study Flood relief scheme designed and planned Planning approval from An Bord Pleanala in August 2008 Emergency Flood Plan employed Sept 2008 On-going media speculation throughout 2011 regarding likelihood of scheme progressing Funding reviewed 2011 = uncertainty Funding allocated Jan 2011 Contracts signed in February 2012 Work pending 20

21 Bray Case Study Survey undertaken between August and September 2011 targeted the population of the flood zone and environs 305 respondents from c. 1,500 properties in 1986 floodplain and within 150m of floodplain Gathered information on: Perceptions Risk Preparedness Awareness Responsibility Insurance Willingness to Pay (WTP) 21

22 Mapping Perceptions Thinking about the Dargle River here in Bray, could you outline as accurately as possible on this map, the likely extent of the area you believe would be affected by a severe flood, for example, a flood similar in scale to that of Hurricane Charlie in

Can t get cover 15% Too expensive 10% I am not concerned about flooding 35% It is not my responsibility 16% Have not thought about it 24% 41

42 Willingness To Pay (WTP) Given the current uncertainty about funding of the Bray Flood Relief Scheme would you be willing in principle to pay towards this public flood relief scheme? Yes 47% No 52% Average WTP 231 p.a. for 5 years 42

43 Conclusions Heightened flood risk arising from climate change. 28% of respondents have experienced some level of flooding 45% believe that their home is at risk of flooding Perceptions of flooding density overlaps reasonably strongly with 1986 historic floodplain 43

44 But, Conclusions Relatively low levels of preparedness Majority believe responsibility for flood clean up and cost of damage lies beyond the householder However, A significant proportion (47%) are willing to contribute in principle towards the flood relief scheme 44
