Soil and Land Suitability Analysis

In September 2009, in Budapest, Hungary, several events were organized to celebrate the 100th anniversary of the first International Conference of Agrogeology. A symposium to review the 100 years of advances in soil sciences and a seminar entitled "From the Dokuchaev School to Numerical Soil Classifications" were organized. As result of these discussions, a resolution (known as the "Godollo Resolution") was prepared and forwarded to the International Union of Soil Science (IUSS) Council for discussion at the 2010 World Congress of Soil Sciences in Brisbane, Australia. The resolution stated that there is a need (i) to develop common standards, methods, and terminology in soil observations and investigations and a universal soil classification (USC) system and (ii) for a new working group to coordinate the efforts of this global undertaking. There was a general agreement that there is a need for evaluation of current spatial soil definition and classification systems and new innovative approaches should be investigated to develop a common universally accepted system. During the 2010 World Congress of Soil Sciences in Brisbane, Australia, the IUSS Council unanimously accepted the Godollo Resolution and formally accepted the proposal for a new working group to carry out the proposed investigations and development of common standards, methods, and terminology in soil observations and investigations and a USC system.
