The Global Nitrous Oxide Budget: A joint new activity of GCP and INI
Abstract
Nitrous oxide (N2O) emissions and atmospheric concentrations have been steadily growing for decades, yet large uncertainties remain on the magnitude, sources and controlling factors of emissions. The Global Carbon Project (GCP) and International Nitrogen Initiative (INI), recognizing the increasing role of nitrous oxide (N2O) emissions in the human perturbation of the climate system and ozone depletion, agree to collaborate in a research effort to establish, improve, and update regularly the global N2O budget. The GCP has a well established reputation working on the global carbon budget (http://www.globalcarbonproject.org/carbonbudget) and global methane budget (http://www.globalcarbonproject.org/methanebudget). The INI is the only project that coordinates scientific and best practices in fertilizer use with a well-established global network of contributors and links to major stakeholders. Together, the projects have the capacity to mobilize the global community and resources to enable an effort: 1) to establish an improved global N2O budget with the capacity to update it at regular intervals (e.g., every two years or longer) with the highest spatial resolution attainable; 2) to foster research developments to improve component fluxes and the overall synthesis of the N2O budget as gaps and opportunities are identified; and 3) to quantify the relationship of the global N2O budget to anthropogenic activities including the extent of adoption of practices to limit N2O emissions. This presentation will provide an overview on the current activity of the GCP-INI global N2O budget, and discuss potential opportunities for collaboration, funding and stakeholder engagement. The first GCP-INI assessment of the global N2O budget is scheduled to complete at the end of 2017.
