The Republic of Mauritius is at the forefront of climate change. The country experiences tropical cyclones, flash floods, droughts and sea-level rise that threaten the land and livelihood of the country’s most vulnerable populations. This policy brief summarizes the current situation of migration, environment and climate change in Mauritius and the country’s policies addressing environmental migration. It recommends the following: (a) Mauritius should take action towards developing the full potential of migration as a positive adaptation strategy to climate change (such as through diaspora cooperation); (b) concretize meaningful actions to build resilience of local communities; and (c) further cooperate with international and regional partners to achieve effective and comprehensive policies on human mobility and climate change.
