Satellite-based map of global mangrove extent and changes: Global Mangrove Watch (GMW)

政策プロセスへの提言

(Japanese title: 世界のマングローブ林面積・変化(GMW))

This submission provides our input for the first Global Stocktake under the Paris Agreement. Our input focuses on a satellite-based map of global mangrove extent and changes: Global Mangrove Watch (GMW).

Summary of the submission:

  • Nature-based Solutions (NbS), including coastal and marine NbS, such as mangroves, are a critical element of meeting the goals of the Paris Agreement for their capacity to sequester and store vast amounts of carbon, commonly known as Blue Carbon, and prevent and minimize coastal erosion and flooding.
  • The Global Mangrove Watch (GMW)  map of global mangrove extent and changes is an open-access geospatial dataset and online tool, derived from a combination of optical and radar satellite data, for tracking changes in mangrove spatial extent, including the progress of mangrove conservation and restoration between the 1990’s and the present.
  • As such, the GMW can be used as a tool for countries that do not yet have their mangrove monitoring systems to design, implement and track the progress of their national climate commitments and identify opportunities to include mangroves in the next round of nationally determined contributions (NDCs), in support of the Paris Agreement’s long-term goals for mitigation and adaptation.
  • The GMW dataset is furthermore used by UNEP to support reporting on Sustainable Development Goals, Indicator 6.6.1 (Change in the extent of water-related ecosystems over time)
  • The GMW dataset is provided by the Global Mangrove Watch and JAXA.
