The Relevance of Economic Data from Forest Accountancy Networks for Forest Management,Research and Politics Consultation

Multifunctional forestry in Germany is characterized by long production periods and highly complex biological–technical processes. Therefore forest enterprises are complex systems, which are closely intertwined with their economic environment. To ensure their economic success, forest enterprises and forest policies need to take the economic development into consideration. The cost accounting scheme of the German Forestry Council provides a basis for management accounting in multifunctional forest enterprises and distinguishes five different production areas whereby intercompany comparisons of different kinds of ownership in forest accountancy networks (FANs) are possible. Results from such a FAN are used to illustrate the economic situation and long-term development of a panel of private forest enterprises. As well these data can support decision-making processes of individual enterprises, forest economic analyses and consultation in forest policy analyses.

Economic weight of tree survival relative to volume production in tree breeding: A case study with Pinus sylvestris in northern Sweden

Abstract

The primary aim of the study was to estimate economic weights of survival relative to volume production per unit area, and to analyse the observable impact of changing survival, for five different breeding populations of Scots pine in northern Sweden. The economic weights were calculated from the model previously presented by the authors. Data from genetic field trials associated with the breeding populations were used both to estimate economic weights and to analyse the validity of the model. The breeding populations used were chosen to encompass a range of climatic conditions. The effects on the estimates of economic weights of increasing harshness (expressed as decreasing temperature sum), actual levels of both survival and patchiness of survival, and different initial stand densities were also analysed. The results showed that an appropriately parameterized model can be used to estimate economic weights for Scots pine in northern Sweden. Both the economic weight of survival and the observable impact of changing survival varied markedly between the studied breeding populations. Decreasing temperature sum had no trend with increasing economic weight of survival whereas decreasing survival and increasing patchiness of survival increased the estimated economic weight of survival more than three-fold.     

Beetles, trees, and people: Regional economic impact sensitivity and policy considerations related to the mountain pine beetle infestation in British Columbia, Canada

This article investigates the regional economic impact sensitivity to the current mountain pine beetle infestation in five study areas of British Columbia, Canada, using a computable general equilibrium framework. Baseline general equilibrium economic databases are constructed for each region using a hybrid data collection approach involving primary and secondary sources. A computable general equilibrium model is constructed for each region and used to simulate the sensitivity of a suite of economic indicators to changes in forestry sector exports resulting from the impacts of mountain pine beetle on the available timber supply. The computable general equilibrium models constructed for each region provides an indication of economic vulnerability to the infestation and can assist decision-makers with the identification of policy considerations and priority areas for mitigation planning in response to the anticipated fluctuations in timber supply.

The regional economic impacts on the development of wood chip utilization in Maniwa city

This paper reports on an empirical investigation about regional economic impacts by the promotion of wood chip utilization in Maniwa city, Japan. We clarify the estimated potential of regional economy development by using input–output analysis for Maniwa city. The result indicates that 315 million JPY of woody chip products can be estimated to generate roughly 448 million JPY of direct, indirect, and induced economic effects. The value of 448 million JPY was equivalent to about 0.2 % of total production value in Maniwa. It is also expected to create approximately 21 jobs by promotion of wood chip utilization. We examined the regional economic impacts on the woody biomass utilization, and evaluated to estimate direct, indirect and induced economic effects, and job creation to clarify the economic impact on Maniwa. We will leave the negative economic effects and the environmental impacts in the process of woody biomass utilization as a future task.
