Abstract Current large-scale environmental and climate change leads to the emergence of new and potentially dramatic risks for individuals and societies. The welfare costs associated with these risks largely depend on our ability to take them into account in decision-making and adapt to new circumstances. By analysing how people perceive and manage risks individually and collectively, this thesis aims to improve the understanding of how these environmentally related welfare costs may be reduced. Papers 1–3 focus on risk perceptions and decision-making at the individual level and concern how people perceive and manage risks in relation to the increasing incidence of Lyme borreliosis (LB) and tick-borne encephalitis (TBE). The empirical analysis is based on a survey with 1500 randomly selected respondents in Sweden. Papers 4 and 5 focus on risk assessment and decision-making at the collective level and concern how strategic environmental assessments are used to manage environmental risks in low- and middle-income countries. The empirical analysis is based on interviews with stakeholders involved in environmental assessments of policy reforms. Paper 1: Learning to Live with Ticks? The Role of Exposure and Risk Perceptions in Protective Behaviour Against Tick-Borne Diseases We analyse the role of risk perceptions and exposure for five protective measures against tick bites and the related diseases TBE and LB. We find a strong positive association between exposure and checking the skin for ticks, but no or weak associations between exposure and the use of protective clothing, tucking trousers into socks, the use of repellent or avoidance of tall grass in areas with ticks. Paper 2: Valuation When Baselines Are Changing: Tick-borne Disease Risk and Recreational Choice We estimate willingness to pay to avoid recreational areas with ticks, LB and TBE risk. In northern Sweden, where the presence of ticks is relatively new, the willingness to pay to avoid risk is significantly higher than in southern Sweden, where ticks ...
