Global change impacts on ecosystem services and the vulnerability
of the human-environment system– The European assessment ATEAM
Dagmar Schröter and Marc J. Metzger
Potsdam Institute for Climate Impact Research
European vulnerability study
ATEAM-project, www.pik-potsdam.de/ateam
17 partners and sub-contractors, Funded by the European Union, 2001-2004.
1. To assess potential impacts of global change on ecosystem services in Europe
2. To translate these impacts into maps of our vulnerability these maps should inform the decision-making of stakeholders about adaptation options to global change
Objectives
Examples of questions to tackle• Which regions are most vulnerable to global change?• Which sectors are the most vulnerable in a certain region?• Which scenario is the least harmful for a sector?
The environmental dimension of vulnerability
• Ecosystems provide services that sustain and fulfill human life (see 1st MA book, Alcamo et al. 2003)
• To know the potential impacts of global change on ecosystem services within a specific region is to understand an essential part of this region’s vulnerability.

Methodology
Consistent global change scenarios
• Spatially explicit: 10' x 10' (ca. 16 x 16 km)• 4 time slices (1990, 2020, 2050, 2080)• 4 Socio-Economic Scenarios• 4 Emission Trajectories (greenhouse gases)• 17 Climate Scenarios (four climate models, one control)• 7 Land Use Scenarios• 4 Nitrogen Deposition Scenarios
As input to our ecosystem and adaptive capacity models.
Sectors, ecosystem services and modelled indicators
Metzger & Schröter 2004 (submitted).
Sectors Services Indicators
Agriculture Food & fibre production Bioenergy production
• Agricultural land area (Farmer livelihood)• Suitability of crops• Biomass energy yield
Forestry Wood production • Tree productivity: growing stock & increment
Carbon storage Climate protection • Carbon storage in vegetation• Carbon storage in soil
Water Water supply (drinking, irrigation, hydropower)Drought & flood prevention
• Runoff quantity • Runoff seasonality
Biodiversity BeautyLife support processes(e.g. pollination)
• Species richness and turnover (plants, mammals, birds, reptiles, amphibian)
• Shifts in suitable habitats
Mountains Tourism (e.g. winter sports)Recreation
• Snow (elevation of snow line)
Agriculture• Decline in arable land (cropland, grassland)
• Surplus land (up to over 10 % of European land surface)
• Land demand for bioenergy may go up, CO2 offset may approach 15% of 1990-emissions in 2080
• Climate driven decline in soil organic carbon, partly counteracted by land use and stimulated plant growth
• Crop suitabilitiy changes; some current agricultural areas become too hot and too dry to support agriculture

Conclusions: Vulnerability• Vulnerable region: Mediterranean seems most vulnerable within Europe -
multiple potential impacts [water, forestry, agriculture, tourism, carbon storage]and low generic adaptive capacity
• Vulnerable sectors: - Agriculture? Soil. Extensification potential. How do farmers decide? CAP...- Forestry? Fire risk. Biofuel potential. Shift to other species.- Carbon storage. Soil respiration and fire vs. net primary production- Mountain tourism. Reliable snowcover declines. Risks and discomfort?- Water. Droughts, floods. Seasonality changes. Hydropower, storage capacity.- Biodiversity. Current debate. Syndrome of impoverishment? Dynamic reserve
management.• Dialogue between science and stakeholders is an important part of the results.
Informed by best science, fair, focussed and sustained. Coordination, moderation, social learning.
• The digital Atlas developed with stakeholders is a useful communication tool in this dialogue.
- What will be most helpful to stakeholders? Maps of V? Maps of AC? Maps of 'raw data'? Which time slices? Scenarios?

Carbon emissions from energy & industry vs. carbon uptake by land use change
Zaehle et al. 2004 (in prep).
Compared to anthropogenic carbon emissions, even the most optimistic potential sink is very small.
