Rising cost of disturbances for forestry in Europe under climate change

Abstract

Climate change has large economic costs for society. An important effect is the disruption of natural resource supply by climate-mediated disturbances such as wildfires, pest outbreaks and storms. Here we show that disturbance-induced losses for Europe’s timber-based forestry could increase from the current €115 billion to €247 billion under severe climate change. This would diminish the timber value of Europe’s forests by up to 42% and reduce the current gross value added of the forestry sector by up to 15%. Central Europe emerges as a continental hotspot of disturbance costs, with projected future costs of up to €19,885 per hectare. Simultaneous climate-related increases in forest productivity could offset future economic losses from disturbances in Northern and Central Europe but not in Southern Europe. We find high disturbance-related cost of unmitigated warming, highlighting that climate change adaptation in forestry is not only an ecological but also an economic imperative. Climate change will raise the severity and frequency of forest disturbance, damaging the economic value of timber. Researchers show Europe’s timber-based forestry could lose up to €247 billion, yet in some regions the increase in forest productivity could offset these shocks.
