The reports entitled “Migration, Environment, Disasters and Climate Change Data in the Eastern Caribbean” are based on a regional study assessing the national and regional data systems on migration, environment, disasters and climate change across the Eastern Caribbean. The set of reports includes one Regional Overview and six National Analyses, and are meant to assist the governments of the Eastern Caribbean in the governance of human mobility related to environmental change, through improved evidence and regional cooperation. The assessments were produced by the International Organization for Migration (IOM) in the six independent member states of the Organization of Eastern Caribbean States (OECS): Antigua and Barbuda, the Commonwealth of Dominica, Grenada, Saint Kitts and Nevis, Saint Lucia and Saint Vincent and the Grenadines, between 2020 and 2021, as part of a project entitled ‘Regional Dialogue to Address Human Mobility and Climate Change Adaptation in the Eastern Caribbean’, with support from the German Federal Foreign Office, in partnership between the IOM Dominica Country Office and IOM’s Global Migration Data Analysis Centre (GMDAC) and in close collaboration with the OECS Commission.
