Economically Optimal Adaptation of Forest Management in the Changing Climate (ECONADA)

Sitemap | Search

Objectives

The project develops stand management schemes that are economically optimal under current and changed climate, as basis for adaptation and mitigation strategies for the Finnish forest sector in the future. Stand development under current and future climate is simulated with a process-based growth model based on light-use efficiency and optimal resource allocation in the stand. The model also incorporates soil nutrient and water dynamics. Simulations are conducted for pine and spruce.

The consortium consists of two subprojects focusing on

1. Economic optimization of forest management, which part is carried out at the University of Helsinki under the leadership of Olli Tahvonen.

2. Ecological modeling that facilitate analyses of stand management in changing conditions.  This part of the project is carried out at Finnish Forest Research Institute, and it’s specific objectives are:

  • To describe the nitrogen dynamics between the stand and the soil with a combined process-based stand growth model and soil decomposition model, and to analyze responses of boreal forests to changes in climate, stand management and tree species composition.
  • To evaluate performance of the soil models and to add a submodel for soil water dynamics simulating weather-related extremities, such as droughts, and their impact on stand productivity.
  • To experimentally test the response of the phenology and the development of photosynthetic activity of tree species to elevated temperature and CO2 concentration.
  • To incorporate a submodel of coarse wood decomposition into the decomposition model and to refine the submodel of tree mortality of the stand model.

The improved stand growth model will provide realistic predictions of stand development, timber production, forest carbon sequestration and impacts of bioenergy harvests in the changing climate. Analysis of the interaction between physiological processes and soil processes will provide a realistic background for the economic optimization of forest management in the changing climate.
