Land-use related environmental indicators for Life Cycle Assessment

Abstract

In the context of life cycle impact assessment, the evaluation of land use impacts needs to be inclusive, incorporating models that allow the quantification of the impact of land use on soil. Soil is a key compartment, determining the supply of ecosystem services as well as supporting biodiversity. The present study reviews and compares a set of models for relating land occupation and land transformation to soil indicators at midpoint level, addressing soil properties and functions as well as threats to soil. Based on a systematic evaluation of available models, considering among other aspects their scientific soundness and ease of applicability for LCA practitioners, this work highlights their strengths and limitations. This allows identifying valuable approaches and research needs for improving the assessment of land use impact on soil in an LCA.
