IPCC SREX & AR5

Global Biodiversity Outlook 4

• Strong coordination of concepts, typologies, language, analyses

• Shared overall chapter structure

• Despite strong coordination, still lacking in study of interactions between Aichi Targets

Synthesis & interactions

Coordination & synthesis meetings

• SREX thematic assessment independent. Working Groups meet independently

• Weak integration across working groups seen as a serious problem.

• Good use of SREX in some parts of AR5, but poorly exploited in WGII

Greater coupling

• Thematic assessments have regional focus, with global synthesis

• Greater coordination of concepts, typologies, language, analyses

• Shared overall chapter structure between thematic & regional assessments

• Potentially improved analyses of interactions between drivers, impacts and responses.
