Message from IUSS President Professor Rattan Lal June 2018

4th June 2018

Please see the latest message from IUSS President Professor Rattan Lal with his views on the Urbanization Challenge. This is an important ramification of the Anthropocene. Several cities may have a population of >70 million by the end of the 21st century. Sustainable management of soils under cities is a challenge to soil scientists that cannot be overemphasized.
