Title: Symposium--Global Soil Mapping in a Changing World

Session Description: Globally ecosystems have been undergoing profound and accelerated change that imposes threats to the functioning and sustainability of agricultural production and natural systems. To assess the distribution, patterns and evolution of soil properties at a global scale under imposed pressures of land use/biome, management and global climate change poses new challenges. Digital soil maps, models, and approaches allow synthesizing our knowledge in support of global soil mapping in a changing world. Concerted efforts are needed to link agronomic and pedogenic perspectives to assess soils at a global scale.

Reviewer's Comments: This session is volunteered papers for a joint ASA Community / S-5 Symposium on Global Soil Mapping. The invited speaker session is on Tuesday, so the numbering of the sessions should be re-ordered, as this is the first of three parts of the symposium - CAS
