From May 14 to 18, 2012, 34 participants from six East Asian countries met in Phuket Thailand to participate in the Sida-sponsored, UNEP/COBSEA Regional Train-the-Trainer Course on Spatial Planning in the Coastal and Marine Zone in the EAS Region. The five-day training course provided instruction by international experts to future national trainers on how to integrate emerging issues such as adaptation to climate change and sea-level rise, and modern management approaches including ecosystem-based management, disaster-risk reduction and marine spatial planning, into national and sub-national spatial planning processes in the coastal and marine environments.
