Inter-Divisional Symposia
Innovation, Speculation and Disneyfication in Soil Science Education
Soil science is a dynamic science but the dynamism is often not reflected in the way that soil science is taught to our students. This symposium addresses soil science education by analysing trends and developments in various parts of the world. Some questions that will be addressed during the symposium are: do we hide our light under a bushel? What are the trends in soil science teaching and student numbers? How do we translate soil dynamics and its role in ecosystem functioning into inspirational learning products? How can we ensure the delivery well-equipped soil scientists for the future?

3.0W Sustainable Soils and Life on Land
The issue of soil sustainability provides an excellent opportunity for a broad community of scientists to engage in a dialog on sustainability and renewable and nonrenewable resource management. While this wide array of disciplines including physical, biological and social sciences have not always worked together, there are many issues where they can and should join forces. Such opportunities include landslides and slope stability; soil erosion and surface runoff; soil quality and land use; chemical, biological, and physical soil processes; carbon sequestration; resource assessment; and expected demand to gain an understanding of sustainable development for

3.3C Improved Management of Alkaline Soils for Dryland Agriculture
Alkaline and saline soils are widespread in dryland farming regions of Africa, West Asia, South Asia, Australia and North America. Crops grown on these soils are often limited by subsoil salinity, sodicity and high concentrations of boron and aluminum. The severity of the soil problems is often overlooked because low productivity is considered to be due to low rainfall. Managing these soils presents some of the least tractable problems of large-scale soil and crop management because of the large number of co-limiting factors.

4.0A Bridging Soil Science, Environmental Policy and Communications
While the relevance of soil science to emerging environmental debates may appear self-evident to the soil scientist, the marriage of science and policy can be difficult to forge.
