Science-Policy Interface Bernhard Schlamadinger [bernhard. schlamadinger@joanneum. at] Science Policy IPCC COP (decision-making) SBSTA (science-policy interface) SBI

How science feeds into the policymaking process Science directly to the COP (via IPCC, „Assessment reports“) Indirectly by lobbying SBSTA and COP negotiators; side events; sci. literature, etc. Technical issues from IPCC via SBSTA è Very specific inquiries from SBSTA è SBSTA approves work plan and results

Technical issues for the scientific community CP 1 issues vs. CP 2 (or longer-term) issues Methodologies Measuring, monitoring and reporting (integrate statistical and env. data) è remote sensing è modelling è forest and soil inventories è flux towers è inverse modelling è especially combining different tools

Technical issues for the scientific community II CP 1 issues cont‘d Focus on uncertainties. Especially soils Demonstrate a pool is not a source Georeferenced data Research towards „National System for estimation of anthropogenic emissions by sources and removals by sinks of all GHGs“ „Reversibility“ of credited C stocks (CDM)

CP 2 technical issues Systems design è Accuracy è Simplicity è Scale Independence è Precedence è Incentives Full C accounting: technical and policy implications è inter-annual variability è verification (e. g. , independent methods such as inverse modelling)

CP 2 technical issues „Factoring out“ è effects of pre-1990 activities è direct human-induced activities (as opposed to CO 2, climate and similar impacts) Deforestation avoidance (esp. baselines)

Science issues related to sinks in the future Robustness of sinks is uncertain è permanence in the long term (land use) è Feedbacks from climate change on biosphere, e. g. emissions from soils Long-term role of CO 2 fertilization? Other feedbacks è albedo changes è local climate etc. Tropics can strongly affect the C balance

Science issues related to sinks in the future II Biomass burning è significant in many regions è UNFCCC only addresses „human induced“ portion Converge top-down and bottom-up estimates Saturation: Technical vs. more constrained potentials; short vs. long-term Research towards a broad systems view, e. g. è leakage, è products and energy sectors

Science issues related to sinks in the future III Land-use policies Economics of land-management Synergies with other land-use objectives è Salinity è biodiversity è desertification è bioenergy è local livelihoods, . . . Link mitigation with adaptation strategies
