Project: Capturing Effects of Diet on Emissions from Ruminant Systems

Acronym	CEDERS (Reference Number: 45)
Duration	01/02/2018 - 31/01/2021
Project Topic	Feed management decisions are critical for ruminant production systems and also strongly affect agricultural greenhouse gas (GHG) emissions. Although ruminant management and production conditions differ between countries, a transnational approach is critical for (i) extending knowledge of ruminant dietary effects on GHG emissions and sustainable production, and (ii) improving GHG accounting methodologies. CEDERS (Capturing Effects of Diet on Emissions from Ruminant Systems), a 3-year proposal submitted to FACCE-JPI ERA-GAS, aims to align national agricultural GHG inventory and mitigation research across an international consortium of 9 countries (8 partner countries plus New Zealand). Its main objective is to delineate dietary effects on various on-farm GHG sources and their trade-offs, at the farm and national scales. Specific aims are to: (1) develop, expand and refine databases to evaluate dietary mitigation strategies on digestion, excretion, manure composition, and related GHG emissions; (2) fill, by experimentation, high-priority knowledge gaps on dietary effects on ruminant and manure emissions; (3) evaluate, using monitored farm cases in a modelling platform, the consequences of dietary mitigation measures on total farm GHG emissions; (4) improve farm accounting and national inventory methodologies to capture effects of dietary mitigation measures for on-farm GHG emissions; and (5) disseminate the implications of these findings to end-users of GHG accounting. CEDERS’s activities will extend to other countries participating in the ‘Global Network’, ‘Network and Database on Feed and Nutrition in Relation to GHG Emissions’ and ‘Manure Management Network’ (both part of the ‘Global Research Alliance’), FAO and CIRAD. These relationships will aid CEDERS to fill knowledge gaps for future GHG research priorities and inventory methodologies and reporting, to governments, non-governmental and advisory/extension organisations and the ruminant livestock sector.
