1. TERRECO Workshop, Seoul September 27-29, 2009 Overview of TERRECO Developments In 2009 John Tenhunen Department of Plant Ecology, University of Bayreuth

2. TERRECO Workshop, Seoul September 27-29, 2009 Critical Problems and Attempted Solutions • Personnel appointed after March 1, 2009 • 36 month limit on appointments of doctoral • candidates • 3. 24 month limit on appointments of post-docs • 4. Planned studies require intensive field effort • 5. Necessary to build up infra-structure in Haean • 6. Necessary to network with cooperative farmers • 7. Visa only allows 3 month stay • 8. Social-science projects require new partners as • well as agreement on scales and integration strategy

3. TERRECO Workshop, Seoul September 27-29, 2009 Critical Problems and Attempted Solutions • Bora, Bumsuk and Eunyoung worked double time • A way was found to support 7 Korean student helpers (ca. 10,000 Euro) • 3. Graduate students were flexible in terms of housing • 4. Mayor‘s office supported establishment of weather • stations, building of weirs, drilling of wells, and • negotiations with farmers • 5. Vacation was taken in Japan • 6. Mr. Park and Mrs. Kwon accepted a new family

4. TERRECO Workshop, Seoul September 27-29, 2009 Accomplishments: Identification of TERRECO Phase I Experiments • Meteorological driver documentation • Landscape variation in structure and function • Integration of processes on slopes • Integration of processes in a sub-catchment

15. Global Change Framework: Climate Land Use Decision-Making (Probability of Land Use and Impacts on Ecosystem Services) (Bayesian Networks and Statistical Methods) Soil Topography Current land use Field and household’s properties Socio-economic factors Policy instruments Mathematical Programming Process-based Crop Yield Model (PIXGRO) Supply side of ASM Markets (producers and consumers) Demand side of ASM Population Alternatives Income Statistical Crop Yield Model Output prices Trade Model Crop literature synthesis Crop statistics • Expected Outcomes • - Future land use maps and impacts on examined ecosystem services • Best management practices with regards to socio-economic and policy systems • Optimal HWB of and trade-offs between producers and consumers • Impacts of climate and market changes and adaptive management strategies

16. TERRECO Workshop, Seoul September 27-29, 2009 Need for an Agency Partnership • TERRECO roadmap diagram • Summary document • Discussions with RIG (Dr. Jeong-Ho Kim)

17. TERRECO Workshop, Seoul September 27-29, 2009 Complex Terrain and Ecological Heterogeneity (TERRECO) Landscape Processes Atmospheric coupling Plant production Biogeochemistry Hydrology and transport DESIRED ECOSYSTEM SERVICES SCALING with respect to GLOBAL CHANGE ISSUES CLIMATE CHANGE SOCIAL-ECOLOGICAL SCENARIO EVALUATIONS AGENCY DISCOURSE ANALYSIS AND MODELING Land use decisions POLICY ACROSS SCALES Social Framework Demography Regulatory policy Economic analysis Land management Land use decisions SOCIAL RESPONSE SUSTAINABLE ECOSYSTEM SERVICES

18. TERRECO Workshop, Seoul September 27-29, 2009 Critical Challenges in 2010 • Escape “crisis mode management“ and build • a TERRECO joint framework and cooperation • Search for co-workers to investigate defined dimensions of TERRECO experiments on site and effectively manage communications • Utilize the TERRECO experiments as a means of overcoming funding imbalance • Focus on problems that will facilitate agency interactions • Develop a supporting data base

19. TERRECO Workshop, Seoul September 27-29, 2009 Way of Proceeding • Review methods and plans for experiments in conjunction with data analysis (winter) • Agree on joint experimental planning (winter) • Final planning of TERRECO experiments (April 2010 workshop in Bayreuth) • Establish experiments in the field (May-June 2010) • Critically evaluate experiments in the field (June 2010 workshop in Haean)
