GEO European Project Workshop - London February CEOP – AEGIS vs. EUGENE CEOP – AEGIS data products properly documented in Status Quo Report Water with accurate linkages to GEO Tasks CEOP – AEGIS not mentioned in the European GEOSS Workshop on Water CEOP – AEGIS irrelevant to European contribution to GEO? Does information on GEO Tasks gets lost in the process?

GEO European Project Workshop - London February Climate Change Adaptation hydrological observations, analyses and predictions mitigate the impacts of climate change remove the underlying causes of vulnerability to climate change Themes: – Short- and long-term hydrological variability and climate change – Resilience versus vulnerability of hydrologic systems – Resilience of hydrological systems to climate variability – Identifying and removing the causes of the vulnerability of hydrological systems to climate change – Reconstruction of adaptation mechanisms to hydrological variability in the recent past Need to integrate very diverse data and models river-wise
