Many policies have been implemented tomitigate the greenhouse gases in atmosphere overall of sectors.With considering the distinct characteristics of the food security, agricultural sectoris no exception to this situation.
To this regard, total amount of carbon which is emitted through all of the agricultural production process is calculated, and being based on this result, the demand for the introduction of agricultural production system with low carbon has been rising. Case studies on the application of life cycle assessment (LCA) technique to agricultural sector are found in many countries. For example, life cycle inventory (LCI) data bases of crop,
farm infrastructure, fertilizer, farm machinery, and etc., have been constructed and provided by Ecoinvent (Swiss centre forlife cycle inventories) of Swiss. In Japan, Top-down typedLCA methodology foragriculture is developed based on the inter-industry analysis, and is evaluated according to the productive method of crop.
On the otherhand, environmental impact assessment of agricultural systemusing LCA inKorea is just in the beginning stages. So it is required to assess environmental impact on agricultural fertilizer and pesticide, and
to develop their flow modeling and methodology of LCA of agricultural sector. Environmental impact assessment on agricultural materials, machinery, and infrastructure will also be carried out.
