What is lca
What is LCA? AGRI-ENVIRONMENTAL PROTECTION TOOL FOR THE SUSTAINABLE LAND USE

Life Cycle Assessment (LCA) is a technique for assessing the potential environmental aspects associated with a product (or service), by:

  • compiling an inventory of relevant inputs and outputs,

  • evaluating the potential environmental impacts associated with those inputs and outputs,

  • interpreting the results of the inventory and impact phases in relation to the objectives of the study.


LIFE CYCLE (MSZ ISO 14040, 1997) AGRI-ENVIRONMENTAL PROTECTION TOOL FOR THE SUSTAINABLE LAND USE

successive and associative stages of the impact system of a product, from the purchase of the raw material or the origin of the natural resource to the recycling or elimination.

LIFE CYCLE ASSESSMENT (MSZ ISO 14040, 1997)collection and evaluation of input, output and potential environmental impacts belonging to the impact system of a product during its full life cycle.

Conclusions
CONCLUSIONS the investigated area

  • The selected indicators can fulfil the role of a suitable assessment tool within the frame of LCA for evaluating the environmental efficiency of agricultural land use.

  • The farm management data and the own established geographical information system can provide a good data source for assessing and calculating the recommended indicators.

  • By assessing the results of the evaluation the investigated cropping system can be considered as an intensive one with less regards to the bio- and geo-physical characters of the land it uses.

  • The above presented indicator system can provide a good basis for comparing different (for instance ecological, extensive or conventional) cropping system according to the quality and quantity of land use.
