Abstract [en]

A method for environmental assessment of agricultural land use is outlined. Environmental objectives and indicators of the land use quality are defined. The method is tested in case studies of cultivated vegetable oil crops: Swedish rape seed, Brazilian soybean and Malaysian oil palm. The results from this study lead us to bclieve that the indicators soil erosion, soil organic matter, soil structure, soil pH, phosphorus and potassium status of the soil, and the impact on biodiversity are a good choice of indicators. These indicators would give a good picture of long-term soil fertility and biodiversity. However, taking them together involves results that are a mix of quantitative and qualitative information, which makes it difficult to aggregate in an acceptable way. Therefore, land use assessment performed in this way includes not only quantitative results but also qualitative descriptions.A method is developed for addressing agricultural land use in life cycle assessment. Based on a set of environmental objectives, a series of quantifiable variables is selected as indicators of the sustainability of the production capacity of agricultural land. These include: soil erosion, hydrology, soil organic matter, soil structure, soil pH, heavy-metal accumulation, phosphorus and potassium contents, biodiversity, and landscape aesthetic value. As illustration, three case studies are presented, involving rape seed production in Sweden, soybean production in Brazil, and oil palm production in Malaysia.
