MAGGnet What is MAGGnet? • Managing Agricultural Greenhouse Gases Network • MAGGnet represents a coordinated, multi-national approach for inventory and analysis of greenhouse gas mitigation research. • Project seeks to compile metadata from experimental sites* throughout the world where greenhouse gas fluxes and soil carbon dynamics are monitored. *[Sites with published data] • Initiated February 2012. http: //globalresearchalliance. org/maggnet/

MAGGnet – November 2016 Ø 23 countries Ø 337 experiments

MAGGnet Contributions Site identification for model inter-comparison exercise (INRA, France): 2014 -present • MAGGnet used to help identify sites for international modeling effort. Template used by GRA Paddy Rice Research Group (NIAES, Japan): 2014 -present • MAGGnet metadata template adapted for rice production in Japan, Indonesia, Philippines, Thailand, and Vietnam. Improved availability of metadata template, map, and sharing agreement: 2015 -present • Online access to MAGGnet information through GRA and GRAMP websites (http: //globalresearchalliance. org/maggnet/; http: //www. gramp. org. uk/). Manuscript published: 2016 • MAGGnet overview paper published in Carbon Management (http: //dx. doi. org/10. 1080/17583004. 2016. 1180586)

Challenges Efforts to include response data ‘flare out’ • Attempted twice (September 2012, March 2016) by adapting a simplified GRACEnet data entry template. • Finding consensus on units seems difficult. Mixed progress on FACCE-JPI effort • Problems with personnel recruitment (ARS) stymied efforts early on. • Preliminary outcomes not novel or inconclusive. Limited number of experimental sites an issue. • Provided travel support for networking purposes. Lack of open access of metadata • Metadata availability limited by the absence of an online home.

Proposed GRA Priority (submitted 8 August 2016) Create a searchable, online meta-database for MAGGnet experimental sites • Adapt within established webpages (GRA, GRAMP) or create anew. • Develop searchable interface to allow users to download metadata based on specific search criteria (e. g. , geographical region, crop, soil type, input use, etc. ). • Initial start-up design costs, followed by recurring support for project updates and metadata input activities. Included among nine flagship proposals, but not supported • What is the role of the GRA in maintaining/supporting/ populating databases? • Access to long-term resources needed.
