In support of the development of European post-Kyoto policies, it is important for European countries to account for the sources and sinks of greenhouse gases (GHG) associated with major land-use classes. In 2004 agricultural land in Ireland accounted for approximately 60% of the total land cover and contributed approximately 27.7% of total national GHG emissions. The CCFLUX project, a collaborative research initiative between Trinity College Dublin, University College Dublin and Teagasc, was implemented to investigate GHG fluxes at the field scale in order to determine the net global warming potential from managed arable ecosystems. Eddy covariance techniques and static chamber measurements were employed to determine the fluxes of CO2 and N2O respectively from a spring barley (Hordeum vulgare) crop which was subject to two tillage management regimes: conventional and non-inversion tillage.

The CCFLUX project had two key objectives: (i) to provide the Environmental Protection Agency with a balance sheet detailing the GHG emissions by sources and removal by sinks for selected Irish land-use categories and to use this information as a basis for developing mitigation strategies to reduce national GHG emissions; and (ii) to equip policy-makers with the process-based knowledge, grounded on a sound scientific understanding needed to make rationally based recommendations for reducing national GHG emissions.
