NITROUS OXIDE EMISSIONS

Nitrous oxide is a potent greenhouse gas (GHG) with a 100-year global warming potential 298 times greater than carbon dioxide. The Intergovernmental Panel on Climate Change (IPCC) estimate that agriculture contributes about 60% of total global anthropogenic N2O emissions, mainly due to nitrogen fertiliser use and emissions from animal waste. However, N2O fluxes from agricultural [...]

CARBON SEQUESTRATION

Carbon sequestration describes the process of transferring carbon from the atmosphere to the terrestrial biosphere (soil or vegetation). Soils contain vast quantities of plant, animal and microbial residues in varying stages of decomposition and store more carbon globally than the atmospheric and living vegetation pools combined. However, there is still large uncertainty surrounding baseline soil [...]

METHANE & THE RUMEN MICROBIOME

Agriculture accounts for the majority of methane (CH4) emissions in Ireland (almost 90%) due to the dominance of cattle and sheep livestock production in Irish agricultural output. These ruminant animals release CH4 as a bi-product of microbial fermentation of food in the rumen and large intestine. This process, called enteric fermentation, produces more than half [...]

INTEGRATED LAND MANAGEMENT

The agricultural sector faces significant challenges in reducing GHG emissions in line with EU targets and maintaining food security. This dual objective must be managed in an integrated way to avoid trade-offs and optimise the sector’s contribution to GHG mitigation and C sequestration. Integrated land management is a coherent approach that incentivises increased food production [...]

MODELLING & DATA COLLATION

In order to improve national GHG reporting and reduce the emissions profile of the agricultural sector, more refined emission factors and flexible inventories are urgently required. AGRI-I has adopted a twin measurement and modelling approach which will facilitate a move towards Tier 2 and Tier 3 country-specific methodologies rather than using Tier 1 default values [...]

AGRI-I WORK PACKAGES

The AGRI-I projects will be implemented in five linked work packages:   WP1: Establishment, management and global outreach of the AGRI-I Consortium Partner organisations: Teagasc, AFBI, UCD, TCD, Maynooth University and University of Limerick WP Leader: Dr. Gary Lanigan (Teagasc)   WP2: Carbon sequestration in permanent pastures and arable soils Partner organisations: University of Limerick, [...]
