1. Science-Policy Interface
Bernhard Schlamadinger
Policy
Science
IPCC
COP (decision-making)
SBI
SBSTA
(science-policy
interface)

2. 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
Very specific inquiries from SBSTA
SBSTA approves work plan and results

3. Technical issues for the scientific community
CP1 issues vs. CP2 (or longer-term) issues
Methodologies
Measuring, monitoring and reporting (integrate statistical and env. data)
remote sensing
modelling
forest and soil inventories
flux towers
inverse modelling
especially combining different tools

4. 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)

5. CP2 technical issues Systems design
Accuracy
Simplicity
Scale Independence
Precedence
Incentives
Full C accounting: technical and policy implications
inter-annual variability
verification (e.g., independent methods such as inverse modelling)

6. CP 2 technical issues „Factoring out“
effects of pre-1990 activities
direct human-induced activities (as opposed to CO2, climate and similar impacts)
Deforestation avoidance (esp. baselines)

7. Science issues related to sinks in the future
Robustness of sinks is uncertain
permanence in the long term (land use)
Feedbacks from climate change on biosphere, e.g. emissions from soils
Long-term role of CO2 fertilization?
Other feedbacks
albedo changes
local climate etc.
Tropics can strongly affect the C balance

8. Science issues related to sinks in the future II
Biomass burning
significant in many regions
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.
leakage,
products and energy sectors

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