GTI RAP for Southeast Asia (2017-2025). The CBD in its Ninth Meeting of the Conference of the Parties (COP 9) has recognized that the global taxonomic impediment constrains the global biodiversity agenda. In response, a GTI Regional Action Plan for South East Asia 2010–2015 was developed by the AMS with China, Japan, and Korea through the ACB. The action plan served as the roadmap in addressing the GTI as implemented in the ASEAN region. This Regional Action Plan 2017–2025 is a continuation of the first regional action plan 2010–2015 and was developed through a workshop with GTI national focal points, some members of the ACB Scientific Advisory Committee, and prominent taxonomists of the ASEAN Member States as participants. The current RAP 2017–2025 will also serve as the roadmap for taxonomy in the region for the next eight years. The GTI Regional Action Plan 2017-2025 shall serve as the roadmap for ASEAN Member States to address the taxonomic impediment in the region. Specifically, the GTI RAP 2017-2025 shall: Guide GTI national focal points in planning activities related to taxonomy; Serve as an instrument in seeking funds for its implementation and other related activities; and Help identify activities that will contribute to the achievement of Aichi Biodiversity Targets 12 (species extinction) and 19 (science-based information and transfer).
