Negotiators in Small Island Developing States (SIDS) are not always well informed and possess limited knowledge on the science and impacts of climate change, although such knowledge is essential for them to engage effectively in dialogue and negotiations relating to climate change. This workshop succeeded in transferring to negotiators and advisors, from nine countries, the much-needed knowledge summarised in the Third Assessment Report of the IPCC, such as vulnerability assessments of the region and policy measures to respond to changes. It also built their capacity to synthesise information for national communications to the United Nations Framework Convention on Climate Change (UNFCCC). This workshop has been regarded as a best practice activity to interface regional scientific outcomes with decision-making processes, and to build capacity to respond effectively to international requirements.
