Various methods were utilized for assessment of soil consumption patterns and trends in the cities of Central Europe within Urban Soil Management Strategy (URBAN-SMS) project. They included ex-post assessment of soil loss based on land use change data, modeling of future soil loss and participatory impact assessment. The major data inputs for ex-post and ex-ante assessments were satellite image...

Forest management often results in changes in soil microbial communities. To understand how forest management can change microbial communities, we studied soil microbial abundance and community structure in a natural Chamaecyparis (NCP) forest, a disturbed Chamaecyparis (DCP) forest, a secondary (regenerated) Chamaecyparis (SCP) forest and a secondary (reforested) Cryptomeria (SCD) forest. We a...
