Public values and preference certainty for stream restoration in forested watersheds in Finland

摘要: Abstract Agriculture and forestry activities increase the deposition of fine sediments in river streambeds, with negative consequences for biodiversity stream ecosystem functioning. However, little is known about economic value headwater restoration associated improvement services. Here, we apply contingent valuation method to assess awareness, knowledge, values held by different stakeholder groups regarding a change set services related sediment-stressed forest streams large boreal catchment. The majority respondents (69%) place positive on restoration. A multiple bound discrete choice (MBDC) format applied sensitivity analysis carried out willingness pay (WTP) respect preference uncertainty. Preference uncertainty support program estimated compared ordered probit non-parametric WTP models. According our study, only 15% more than 450 are completely certain their preferences. Higher certainty significantly correlated with, example, stated easiness revealing household's WTP, trust program, living conditions trout, addition lower education level. Making benefits visible involving public stakeholders projects could help setting targets, creating effective plans better support, establishing stronger basis funding efforts.
