Todays menue • Challenges, methods and tools to analyseecosystemsservices on the regional scale • Modeling & Analysis • Global vs. Regional Scale • Project (GLUES) and research programme in Germany • Database • Synthesis • Model-based analysis
Global vs. regional assessments • Land management is a regional process • direct feedbacks between ecosystem services and human well being • Regional case studies are key • What are the feedbacks between regions? • How to synthesize regional results? Roudsepp-Haerne et al. (2010, BioScience) • Human well-being and ecosystem services show globally different trends. Why? • Reject Hypothesis • Lack of data? • Lack of undersrtanding • Wrong Scale?
Global pollination demand Lautenbach et al. (in prep)
Examplepollination • Lautenbach et al. (in prep)
Experimental results on pollination • Summer 2010 Experiment: • Distribution of bee netsts • Yield increase of 20% Apple yield [kg/tree] ** no yes beesreleased • Dorman et al. (subm.)
Analysis of feedbacks: artificial landscapes • Recreation = f(forestarea, shape) • Production = f(fielsize, pollination, soilfertity) • Pollination= f(forestedge) Generation 800 10 Generations Generation 1 ~lineare Trade-offs Non-linearTrade-offs
Spatialconfiguration Pollination
Parthe basin and biofuel production • study trade-offs between bioenergy production, food production, water quality and water quantity • Varyation of the crop rotation schemes • Objective function: • 5 percentile discharge • Average NO3- concentration • Yield food production • Yield bioenergy crops Modifications
Results scenario analysis • trade-offs regarding scenario assumptions • but: how good are the scenario assumptions? Strauch 2010, Strauch, Ullrich, Volk 2010
Generation 2, e.g. Monte Carlo Analysis • Use of genetic algorithms for variation of crop rotation, e.g. variation of land use intensity
Generation 100 - 500 • Processes • Food yield ~ Bioenergy yield-1 • NO3 ~ Food yield-1 • NO3 ~ Bioenergy yield • Uncertainty • Hydrology: high (equifinality pattern) • Yield: low

Conclusions & Next Steps • Conclusion • Trade-offs: Separate (landscape) pattern and process! • Bundles of ecosystem functions/services are determined by patterns (landscape) and processes and are non-linear. • Next Steps • Regional focus demands synthesis of place-based studies • Blueprint or standardized prototokoll required • This is a prerequisite for standardized data-bases • Modelling, requires data based backgrounds
Review: Regional Ecosystem Services Studies • Considered uncertainty • Data source • Ecosystem services in isolation • Modelling approaches • Valuation • Number of ecosystem services • Scenario-Analysis • Specific recommendations • Stakeholder involvement Seppelt et al. (2011, JApplEcol)

Review: Regional Ecosystem Services Studies It is unclear to what degree biophysical realism is required in ecosystem service assessments Methods to analyze trade offs among ecosystem services and economic goals are not well developed Consideration of off-site effects is extremely rare Involvement of stakeholders rarely extends to the implementation phase (‚ownership‘) Seppelt et al. (2011, JApplEcol) Seite 23

GLUES Overarching Scientific Support and Synthesis GLUES: Global Assessment of Land Use Dynamics, Greenhouse Gas Emissions and Ecosystem Services Communication & Outreach Stakeholder & Products Szenario, Models & Synthesis Common Geodata Infrastructure
GLUES’ methodology • GLUES GDI (Geodata Infrastructure) – provides a common infrastructure to publish, share and maintain distributed global and regional data sets, scenario data and model results. • Mid-Term Projections (2030/50) – incorporate feedbacks of agricultural markets, land use and climate • Long-Term Scenarios (2100) delivers land use change scenarios based on global sustainability goals and climate change, to be used to project land management impacts on global climate. • Synthesis develops methods and tools for trade-off and off-site effect analysis, valuation of ecosystem services and support instruments development
GLUES GDI • Concept • Global distributed Geodata Infrastructure: Data ramains with the owner • INSPIRE Conform • Links up GLUES partners • Links up regional projects (in Version 1) • Open to the community (in Version 2) • Content & Function • Holds global data land use, ecosystem services, scenarios, climate change etc. • Harvests available databses • (FAO, IUCN based on standardized links) • Product • embeddeable in Google Earth, ArcGIS • Prototype for internal testing available • Version 1 available 1/2012
GLUES modelling concept • Concept: Global scale • Model based generation of Scenarios on land use, climate change pattern for short and long term scenarios • Concept: Regional Scale • Generec ESF/ESS Models of intermediate complexity relating land use (change/intensity) to ecosystem services • Using knowlege form well tested established system • Covering processes in hot spot regions • Partly meta-model to cover processes from regional projects • Analysis • Analysis of trade-offs via optimization and Monte-Carlo Simulation • Analysis on off-site effects
GLUES synthesis • Concept • Use of avaliable data on regional ecosystem service assessments (meta-analysis, accross projects: TEEB, Conservation Internation, etc.) • Use network and statistical analysis • Analysis • Relate Environmental and Economic Conditions and assessed Ecosystem Services • Identification of threasholds, nonlinearites
Someconcluding statements • Diversity of model developments is beneficial for scientific progress but might be contraproductive for ecosystem service assessments • Off-site effects and trade-off analysis are core challenges for regional studies • Biophysical realism of models supporting ecosystem service assesments is support by systematic analysis
Thank you for your un-prejudice attention! Questions welcome: ralf.seppelt@ufz.de (I forgot my cards)
SomeConcluding Statements • Various models and tools are helpful for untangling relationships between land use (intensity) and ecosystem services. In which do we belief? • Modeling provides virtual experiments with landscapes. How not to loose realistic constraints? • Regional resources management is embedded in global processes. How to be quantify off-site effects? • Need for research in appropriate development of reliable instruments and tools for supporting the Ecosystem Service Concept
