Technical Abstract: Multi-national greenhouse gas (GHG) flux networks play a central role facilitating model development and verification while concurrently identifying critical research needs. In 2012, a network was established within Component 1 of the Global Research Alliance (GRA) Croplands Research Group. The network, referred to as MAGGNET (Managing Agricultural Greenhouse Gases Network), sought to establish a coordinated, multi-national approach for inventory and analysis of GHG mitigation research specific to croplands. Initial MAGGNET activities focused on collection and organization of metadata from experimental sites where soil C dynamics and/or GHG flux had been part of the data collection protocol. Ten GRA countries (Argentina, Denmark, France, Indonesia, Italy, Japan, Korea, Spain, Uruguay, and USA), encompassing 123 unique experimental sites, contributed information in response to the initial metadata call. Follow-on activities have expanded collected metadata using published experimental site information, thereby establishing a foundation for inclusion of key response metrics (e.g., GHG flux, soil C stock changes, crop yields). MAGGNET aims to leverage data collected at cropland experimental sites throughout the world in order to strengthen estimates of GHG mitigation effectiveness from targeted management practices while identifying opportunities for additional field research. Moreover, network activities will be coordinated with ongoing C and N modeling efforts within the GRA Croplands Research Group (Component 3) and C/N Crosscutting Research Group, potentially improving national inventories of GHG emissions. Collectively, MAGGNET should serve to strengthen collaborations among scientists and contribute to the overall goal of the GRA Croplands Research Group, which seeks to reduce GHG intensity and improve overall production efficiency of cropland systems throughout the world.
