1. 1 CHARGE The goal of the breakout groups is to –define and prioritize research questions to help guide the US Global Change Research Program, –determine the relative priorities of the research questions, and –designate whether research priorities are sufficiently mature for short-term research or are more long-term in scope.

2. 2 Breakout #2 Questions What ecosystem observations are needed to improve our understanding of carbon on land? What land-use observations are needed to improve our understanding of how carbon can be managed?

3. 3 Breakout Notes Session 2 Group 3 Land-use conversion resolution - Spatial -Ex: Fertilize/Irrigate (yard-by-yard basis) -Push toward finer scale resolution -Trading done at plot-level -Wetlands - Temporal -Annual LUCC map -Annual statistics

4. 4 Breakout Notes Session 2 Group 3 Approaches of Observation: - Foresters -Structure - Inventory: -Remote Sensing -Soil carbon - Ecologist -LAI

5. 5 Breakout Notes Session 2 Group 3 Land Management Information - Surveys - Not statistical -Mapping management -Privacy issue - Historical Info -How and why land is changing?

6. 6 Breakout Notes Session 2 Group 3 Compliance Program - Anything C = international - Internal and global compliance - Policy and observations must be compatible Urban Interface - Need information at wildland/urban interface

7. 7 Breakout Notes Session 2 Group 3 Projection Models - What would go into a projection model? -How much seed was sold? -Policy? - Domain-specific / base-line information -Soils -Historical -Trend vs. Business –as-usual -How do you know what business-as-usual looks like in the future?

8. 8 Breakout Notes Session 2 Group 3 Soil - Better sampling methods -Goals? -What about other countries? Lateral C Flux - Water transport Wetlands - Production of methane (more attention)

9. 9 Breakout Notes Session 2 Group 3 Other environmental changes concurrent w/ LUCC - N deposition -> Uptake of C?? - Corridors - Fire - Insects - N-Cycle

10. 10 Breakout Notes Session 2 Group 3 Socio-Economic - The end result -Policies set on transportation and social planning - GDP? - Transportation sector

11. 11 Breakout Notes Session 2 Group 3 Forest conversion -Rate -Pattern -Fragmentation -Degradation -Fire -Edge-effects -Regeneration Integrate Data Sets -R.S. data with ground-based measurements -Socio-economics and policy

12. 12 Breakout Notes Session 2 Group 3 Atmospheric Measurements - Inverse modeling -Can it evaluate country contributions? Data Management - Collaborative Modeling? - Meta-data

13. 13 Research Questions – Session 2 Research question/topicPriorityMaturity What is a useful observation strategy for C compliance monitoring and reporting system? (multiple elements) 1S What are the drivers of these land use transitions and how can they be used to construct base-line information? 1S How can we improve or refocus carbon-specific allometry? (global) 1L How can we design a national carbon-specific soil sampling methodology? 1L How can we better estimate/model lateral transport of C? 2L How can we better estimate/manage methane?2L

14. 14 Research Questions – Session 2 Research question/topicPriorityMaturity We know the area of fire and insects, but what about the impact on C? 1S What are the socio-economic indicators of C storage and change? (development patterns, e.g. transportation network pattern) 1L Questions of policy/time/spatial scale?3L What is the magnitude rate and pattern of forest conversion? Fragmentation? Degradation? Fire? Edge- effect ? 1S How can we best manage and deliver collected data?1S
