Valuation of terrestrial and marine biodiversity losses caused by forest wildfires

摘要

This study presents an economic valuation survey to estimate the social demand of a convenience sample for undertaking forest management measures aimed at reducing the negative impact of forest fires on terrestrial and marine ecosystems. The paper spans the traditional focus in forest economics by considering also the negative effects caused by forest fires in coastal areas, highlighting this way how the externalities go beyond the terrestrial area and can also affect marine ecosystems. Results from a willingness to pay in space modelling approach show that people are sensitive to the biodiversity losses produced by forest fires and are willing to pay (work on a voluntary basis) to undertake activities that reduce their impact. The main negative externalities are concerned to the terrestrial wildlife (animals and vegetation), following by the erosion and marine biodiversity losses and the pests and diseases prevention.
