The International Union of Soil Sciences (IUSS) is the global union of soil scientists. The objectives of the IUSS are to promote all branches of soil science, and to support all soil scientists across the world in the pursuit of their activities. This website provides information for IUSS members and those interested in soil science.



TROP ICSU (“Trans-disciplinary Research Oriented Pedagogy for Improving Climate Studies and Understanding”) is a global project funded by the International Council of Science. The project is led by International Union of Biological Sciences (IUBS) and co-led by International Union For Quaternary Research (INQUA).

IUSS is partner in the project and supports the project by contributing soil related content and by carrying out local workshops (see:

TROP ICSU provides digital/ICT-based teaching resources that integrate climate studies across the curriculum of Science, Mathematics, Social Sciences and Humanities. These teaching resources (Teaching Toolsand  Lesson Plans) are locally rooted in their context, but globally relevant for their science. Please find the most recent project updates here: monthly newsletter 

The TROP ICSU team would be glad to learn from your experience related to soil simulators. If you and/or your colleagues are aware of such tools, please submit web links to either projects or web tools that are related to climate change and soil to
