JAXA's SAR Satellite Tech to Assist the UN

The Food and Agriculture Organization of the United Nations (FAO) will bolster the scale and scope of the organization's geospatial monitoring toolkit, thanks to collaboration with the Japan Aerospace Exploration Agency (JAXA) that will expand the capacity of FAO's accessible platforms for forestry and land-use assessments.

A signed, three-year agreement will enhance the access of FAO member states and other users to JAXA data sets and more "ground-truthing" evidence through FAO's forest monitoring platforms.

Technically, the new collaboration will expand the scope and usability of FAO platforms such as SEPAL and the Global Forest Resources Assessment Remote Sensing Survey, while also boosting the granular accuracy of JAXA-led initiatives that cover the world's mangroves as well as forestry and land-use themes in general.

JAXA uses L-band Synthetic Aperture Radar (SAR) technology which has a unique feature of being able to observe the Earth's land surface regardless of time (day and night) and weather (rains and clouds) with waves with especially long wavelengths, allowing to accumulate both vegetation and ground information.

The next steps include offering reciprocal access to select data and FAO and JAXA will conduct training workshops for FAO member states and integrate the data FAO's Open Foris platform. FAO's geospatial toolkit, including SEPAL (System for Earth Observation Data Access, Processing and Analysis for Land Monitoring) has more than 4,300 active users from 160 countries and offers anyone easy-to-use access to satellite data and super computing power, allowing them to create critical forest and land cover information in their efforts to mitigate and adapt to climate change.

The SEPAL platform is built on collaboration and partnerships, and JAXA joins Google, NASA, ESA, Planet, and the World Bank as contributors to the platform. The SEPAL project is funded by Norway's International Climate and Forest Initiative (NICFI).

FAO expects the collaboration will benefit its ongoing work on forest, peatland and mangrove monitoring and assessment, areas in which JAXA initiatives including the Global Mangrove Watch and JJ-Fast, a forest, early warning system in the tropics established by JAXA and the Japan International Cooperation Agency (JICA).

Daniel Gustafson, FAO's Deputy Director-General for Programs who signed the agreement, said that as deforestation and land-use changes are one of the leading sources of global carbon emissions, satellite-based information has a critical role to play in supporting countries to achieve their commitments on climate change.

JAXA Vice President Imai Ryoichi noted that for over 20 years, JAXA has accumulated global L-band SAR data, which is essential to understand changes in forests and predict their future. JAXA expects the satellite data to be used to support sound decision-making, adding that the application of L-band SAR data would be further required in a variety of areas to tackle global agenda and that JAXA stands ready to contribute in remote sensing areas.


"This is the kind of partnership that smartly leverages skills and resources to boost our knowledge base and potential impact," said Hiroto Mitsugi, FAO Assistant-Director-General of the Forestry Department.
