Forest disturbances in Europe are very likely to increase in frequency and intensity. Assessing their economic consequences is required to identify feasible adaptation strategies. Such economic calculations depend on estimates for the reduction in revenues after disturbance events. These losses can be caused by both a lower wood quality as well as an oversupply on the wood markets. Despite its importance, data-driven approaches to quantify the consequences of disturbances on wood revenues in Central Europe are rare. We applied econometric time series analysis with Structural Vector Autoregressive (SVAR) models to harvest and sales data from Hesse, Germany. Additionally, we derived estimates for reductions in wood revenues for integration in bioeconomic simulation models. Our analyses indicate that the observed losses in wood revenues for spruce after disturbances are mainly due to an oversupply on the wood markets, rather than a loss in wood quality. In addition, the results suggest that calamities of transregional extent or multiple disturbances in subsequent years are likely to reduce wood revenues beyond the assumptions often used in bioeconomic simulation models. Although our results for beech were more ambiguous, they indicate that losses in revenues for beech after disturbances in the past were mainly due to a reduced wood quality. Our study highlights the importance of taking a differentiated view on the consequences of disturbances on wood revenues, considering their spatial extent and species-specific mechanisms.

使用脉冲响应函数量化干扰对木材收入的影响

欧洲的森林干扰很可能会增加频率和强度。需要评估其经济后果以确定可行的适应策略。这种经济计算取决于对干扰事件后收入减少的估计。这些损失可能是由较低的木材质量以及木材市场供过于求造成的。尽管它很重要,但量化干扰对中欧木材收入的影响的数据驱动方法很少见。我们应用计量经济学时间序列分析和结构向量自回归 (SVAR) 模型来收集和销售德国黑森州的数据。此外,我们得出了对木材收入减少的估计,以将其整合到生物经济模拟模型中。我们的分析表明,在干扰后观察到的云杉木材收入损失主要是由于木材市场供过于求,而不是木材质量下降。此外,结果表明,跨区域范围的灾难或随后几年的多重干扰可能会减少木材收入,超出生物经济模拟模型中经常使用的假设。尽管我们对山毛榉的结果更加模棱两可,但它们表明,在过去的干扰之后,山毛榉的收入损失主要是由于木材质量下降。我们的研究强调了对干扰对木材收入的影响采取不同观点的重要性,考虑到它们的空间范围和特定于物种的机制。而不是木材质量的损失。此外,结果表明,跨区域范围的灾难或随后几年的多重干扰可能会减少木材收入,超出生物经济模拟模型中经常使用的假设。尽管我们对山毛榉的结果更加模棱两可,但它们表明,在过去的干扰之后,山毛榉的收入损失主要是由于木材质量下降。我们的研究强调了对干扰对木材收入的影响采取不同观点的重要性,考虑到它们的空间范围和特定于物种的机制。而不是木材质量的损失。此外,结果表明,跨区域范围的灾难或随后几年的多重干扰可能会减少木材收入,超出生物经济模拟模型中经常使用的假设。尽管我们对山毛榉的结果更加模棱两可,但它们表明,在过去的干扰之后,山毛榉的收入损失主要是由于木材质量下降。我们的研究强调了对干扰对木材收入的影响采取不同观点的重要性,考虑到它们的空间范围和特定于物种的机制。尽管我们对山毛榉的结果更加模棱两可,但它们表明,在过去的干扰之后,山毛榉的收入损失主要是由于木材质量下降。我们的研究强调了对干扰对木材收入的影响采取不同观点的重要性,考虑到它们的空间范围和特定于物种的机制。尽管我们对山毛榉的结果更加模棱两可,但它们表明,在过去的干扰之后,山毛榉的收入损失主要是由于木材质量下降。我们的研究强调了对干扰对木材收入的影响采取不同观点的重要性,考虑到它们的空间范围和特定于物种的机制。
