Five years after the publication of the first ASEAN Biodiversity Outlook (ABO 1),
the ASEAN Centre for Biodiversity (ACB) once again reviews the progress of the ASEAN
towards the achievement of milestone targets in global efforts to reduce biodiversity loss. In
the midst of the implementation of the Strategic Plan for Biodiversity 2011–2020 and Aichi
Biodiversity Targets of the Convention on Biological Diversity (CBD), the second edition
of the ASEAN Biodiversity Outlook (ABO 2) discusses ASEAN’s progress in achieving the
Aichi Biodiversity Targets, the state of major habitats in the region, and the many factors
that influence and contribute to their effective management.
