• „Avoiding dangerous climate climate change“
– science-based policy support from
observations and modelling
• From land cover change to land use change
• Earth system implications of land use change

Policy support for safeguarding the global
environment presently concerns Earth
System Interactions more than ever:
• Impacts of climate change on human life-
support systems on land and in the ocean
• Feedbacks from changing land (and ocean)
use to the atmosphere and climate
• Interactions between land and ocean

Policy support must be
• based on international conventions
• science-based & peer-reviewed
• use the best available information
This demands an assessment process (e.g.,
IPCC, Millennium Ecosystem Assessment)
which takes into account findings from Earth
Observation, process modelling and other
methods.
