Urban soils research: SUITMA 10

Research on Soils in Urban, Industrial, Traffic, Mining and Military Areas (SUITMA) has been presented at biennial SUITMA conferences held in cities around the world. Soils from these areas often present environmental, ecological, and health risks and can limit ecological functions and ecosystem services. However, as with all soils, they are an integral part of the local ecosystem. In urban areas in particular, soil is a critical resource and can play a key role in the long-term sustainability and resiliency of cities. This special section contains five papers from the SUITMA 10 conference held in Seoul, South Korea, in 2019. They cover diverse topics that include urban soil properties, risk from contaminated soils, biological indicators for ecological functions, air deposition in urban gardens, and international summer field school opportunities. This section highlights research on anthropogenic soils conducted by the SUITMA community to promote better understanding and management of these soils.
