Second Symposium on Community-based Activities and Governance for Seascape Restoration


Date: 20 Sep 2022  

Time: 13:00-16:30 JST 

Venue: Online  

On 20 September 2022 UNU-IAS will co-host an online symposium on community-based activities and governance for seascape restoration. This symposium will be the second in the Satoumi and Ecosystem Restoration Symposium series. Focusing on blue carbon systems restoration—mangrove, seagrass, and salt marshes—and citizen science application, the symposium will feature practitioners of blue carbon ecosystem restoration from around the world and discuss how we can enhance and strengthen restoration efforts.  

The symposium series aims to build momentum towards the UN Decade on Ecosystem Restoration for coastal ecosystems, creating a network of stakeholders for Satoumi restoration. It will share information on good practices and challenges, and identify gaps in restoration to develop policy recommendations. 

The event is co-organised in partnership with the Ocean Policy Research Institute, the Ministry of the Environment, Japan (MOEJ), and the United Nations University Institute for the Advanced Study of Sustainability (UNU-IAS). 


The event will be held in English and Japanese.
