The objective of the present study is to build institutional capacity and knowledge to enable Nauru to improve plan and manage the impacts of climate change on migration. Through the development of indicators, the provision of new knowledge on labour migration and by analysing community attitudes to climate-related migration the report aims to both help the development of effective responses to climate change and national strategies to mitigate displacement risk and enhance national capacity to effectively participate in regional, bilateral and global schemes on labour migration. This report is the first national empirical study representing the relationship between household vulnerability, human mobility and climate change in Nauru. The report is based upon accumulating data through quantitative and qualitative fieldwork carried out in Nauru in early 2015 by researchers from the United Nations University Institute for Environment and Human Security (UNU-EHS), the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP) and University of the South Pacific (USP).
