The Cost

A key principle for achieving Tolerable Risk under the UK Health and Safety Executive’s (HSE) approach is the reduction of risks to “As Low As Reasonably Practicable” or ALARP. This principle is founded on the ideal of reducing risks to a point of diminishing returns where additional risk reduction would cost “disproportionally” more than the risk reduction benefit achieved. The HSE approach of estimating the degree of disproportionality between the cost and benefits associated with a potential risk reduction measure is a variation of the Cost Effectiveness approach to ALARP Evaluation. A probabilistic cost-benefit analysis method is outlined for evaluating design options and establishing whether the conditions of ALARP are met. This paper demonstrates the value of probabilistic cost-benefit analysis for the selection of a target safety level and also presents an example of its practical application by way of a case history.

Abstract. Citizen observatories are a relatively recent form of citizen science, which involve citizens in making environmental observations over a period of time. These observations can help to inform the decision making of local authorities and other stakeholders, creating a platform for two-way interaction between citizens and public agencies. Although citizen observatories can clearly generate many different benefits, they also have an associated cost. There are currently no examples of quantifying the costs and benefits of citizen observatories in the literature, yet this type of analysis is critical if there is to be real uptake of citizen observatories by public agencies more generally. This paper presents and applies a generic methodology for capturing the value of a citizen observatory for flood risk reduction in the Brenta-Bacchiglione catchment using a cost-benefit analysis. The results show that the benefits of implementing a citizen observatory approach outweigh the costs by approximately 2 to 1 and can reduce the annual expected damage to a greater degree than a much more costly structural approach.
