4TG5 Asia-RiCE meeting at AOGEO 16
Meeting Objectives
1. To discuss EO for climate mitigation /adaptation of rice farming forfood security and low carbon strategy in Asia-Oceania region. Thefocus is on the reduction of methane emissions by paddy fields
2. To initiate the multi-lateral research network in the region
3. To discuss with various stakeholders including private sector

5Summary of the TG5

Summary of

I. Achievements

1. Rice monitoring in Asia-Oceania region
Implement platforms for sharing of open data with standard format such as
CEOS ARD and tools is being established in Asia-RiCE, contributing toimproved agricultural statistics, agricultural policy making and beyond,
2. Multilateral network for agro-meteorological info and rice monitoring
Provision improved agromet information and rice crop monitoring to Asia
Ocean region and promote regional cooperation on data and information
sharing using available platform and knowledge sharing.

Summary of the TG5
II. Ongoing Issues
1. Provide earth intelligence using EO data with ground based data including automatic
measurement by IoT for Asia-Rice,
2. Satellite based water monitoring in paddy fields - CH4Rice:
Need to study water management of rice field (drainage –AWD Alternate Wetting andDrying) using remote sensing and ground based data, in order to reduce methane
emission (CH4) from paddy fields,
3. Yield estimation and damage assessment:
Need to assess damages caused by climate change including floods, droughts, salinity
intrusion, subsidence etc. and rice yield estimation and forecasting by integrating
remote sensing and models with weather forecast and climate predictions,
4. Derive adaptation and mitigation measures for stakeholders (e.g. using dashboard)7

Summary of the TG5
III. Way forward for post-2025
1. To discuss EO for food security and climate adaptation/mitigation in Asia-Oceania
region with ongoing issues described previously,
2. To seek international guidelines, especially for carbon trading regarding methane
emission from paddy fields,
3. To strengthen cross comparison between different countries and sharing
methodologies and validation results,

4. To promote collaboration with various stakeholders both public and private sectors
for the operational use of these achievements,
5. To promote continuous capacity building, young researchers support and field survey
using available funds such as international donors and governments etc.
