Background and Goals
The SAFE project is studying possible effects of global change on forests and forestry in Europe. The main objective of the project is to assess possible effects of global environmental changes on Europe's forests. This relates to the effects on growth and species composition of the forests, forest management and the forest economy, and the secondary forest functions.
The studies are being carried out on three different scales with different levels of detail. On a European scale, the studies are concentrating on regional changes in ecological factors and on assessing the potential development of natural and managed forests. On a national scale, the focus is on the sensitivity of existing forests and forestry in Germany to climate changes. On a regional scale, an integrated analysis and assessment of the ecological and socio-economic effects of climate change are being performed.
The following activities are being carried out:
- Development of an improved forest model for assessing ecological effects of global change, including a sub-model for forest management;
- Development a model for timber production and the socio-economic consequences;
- Establishment of a database for climate, climate change scenarios and current forest conditions;
- Model validation for the three geographical scales;
- Integrated assessment of effects for the forest sector at all levels.
- North-East German lowland
- South-Eeastern basin and hills
Steps in the process of adaptation to climate change
Step 1: Understand and describe climate change
A basic scenario and a climate change scenario with a temperature increase of 1.5°C and 3.0°C are being used. These are based on the global climate models HadCM2 and ECHAM4.
Simulation models for forest development are being developed and applied. Model development is focused on the so-called "forest gap model" 4C (FORESEE - Forest Ecosystems in a Changing Environment). The existing FORSKA and FORCLIM models are being used for the sensitivity analyses and regional studies. Using the basic scenario, the FORSKA model simulates the potential natural vegetation (PNV), which is compared with a map of the PNV for Brandenburg. In conjunction with the SANA project (Atmospheric Clean-Up for the Former East Germany), the FORSANA growth model for pine forests has been extended and applied to various scenarios for air pollution and climate.
- Higher average temperatures
Step 2a: Identify and assess risks - climate effects and impact
The climate effects for managed forests in the regional water and carbon cycle are being studied. In addition, the functions and services provided by the forests are being evaluated under global change. The effects of climate change and management on ecosystem services of carbon storage, biodiversity, water conservation and production, and leisure and recreation are being analysed.
Step 2b: Identify and assess risks - Vulnerability, risks and chances
There are shortcomings in the transfer of scientific findings into practical recommendations for action.
In forestry, there is a need for sustainable ecosystem management to cope with global change. To ensure environmentally friendly forest management and forestry in the long term, improved instruments for predicting forest development are required. This is not just important for individual ecosystems but where possible in the context of entire landscapes, taking account of water and material balance studies.
Step 3: Develop and compare measures
