Sustainability of intensified agricultural production in the Boyne catchment.

Abstract
Food Harvest 2020 is a national plan for intensification of agriculture with specific
targets to be delivered by 2020. The plan envisages increases in output across a range
of farm enterprises – dairying, beef, sheep and pigs. The motivation for this study was to
examine the environmental sustainability of the Food Harvest 2020 targets. The study
was carried out on the River Boyne catchment area.
A wide-ranging environmental systems analysis was carried out to assess the
environmental impacts associated with the intensification of agricultural production
envisaged in Food Harvest 2020. The following environmental impacts were assessed
using Life Cycle Assessment (LCA) modelling: Global Warming Potential, Primary
Energy Use, Eutrophication Potential, Acidification Potential, Abiotic Resource, Pesticide
Use and Land Use. Ideally, one would aim for a full LCA approach for all commodities in
the agricultural sector. However, this was not possible because of the complexity. The
scope of the study was therefore limited to 10 arable crops and 4 livestock production
systems.
Following an extensive review of the literature and consultation with expert opinion,
the Cranfield LCA Systems Model was selected to carry out the analysis. This model
proved to be very suitable as it was specifically developed for agricultural purposes.
The modelling identified significant increases in environmental burdens associated with
intensification of milk production, beef production and pig production. There are a
number of strategies that could mitigate or offset to some degree the increased
environmental burdens. The recommendation from this study is that the
implementation of Food Harvest 2020 should be tied to a package of transparent and
verifiable mitigation measures. Some of the mitigation measures may be cost neutral
and others may not. In any case business as usual is not a sustainable scenario.
