Former Research Fellow
Ocean Policy Research Institute of The Sasakawa Peace Foundation

Nagisa Yoshioka had been a Research Associate at the Ocean Policy Research Institute since November 2019.

Her research interests include Climate Change Adaptation and Disaster Risk Reduction (CCA and DRR), with a special focus on social vulnerability in developing countries. She has been involved in several research projects on climate-induced migration, climate risk insurance, and coastal community vulnerability. She also has extensive experience in field studies in Asia-Pacific countries, including Thailand, the Philippines, Fiji, and the Marshall Islands.
Prior to joining OPRI, she played a leading role in a Japanese youth NGO for climate action and engaged in advocacy and awareness rising activities. She has put great passion into protecting human security in the context of climate change and disasters, both as a researcher and an activist.
Nagisa is currently focused on “Climate Change and Ocean” topics and is involved in activities at the UN Climate Conference (UNFCCC-COP). Furthermore, she is a part of the joint research project with the Stimson Centre, titled “Climate and Ocean Risk Vulnerability Index (CORVI)”, which quantifies diverse climate and oceans risks at the city level in the Asia-Pacific region.
