Brief history and objectives
The Experimental Geomorphology and Soil Erosion Group (GEES) started its activities in Guarapuava in 1998 with research on erosion and soil degradation in yerba mate plantation. Currently the group has a national and international repercussion in topics such as: fire effects on soil properties and soil erodibility-erosion in agricultural systems. The GEES research group aims to: 1) Educate scientists in geography and related fields; 2) Produce knowledge in Geomorphology and Pedology and to promote the sustainable use of soil and water in catchment; 3) Produce knowledge about the hydro-erosive dynamics of tropical and subtropical soils; 4) Create and disseminate studies in Experimental Geomorphology based on Earth superficial processes. The Group currently has two research laboratories: a) Hydrogeomorphology (Irati) and b) Soil erosion - AMBIOTEC link - Guarapuava. Among the main equipment of the group are rainfall simulators for use in the field and in the laboratory.
Main research topics
- Experimentation and soil erosion monitoring
- Fire effects on soil properties
- Soil quality, degradation and recovery
- Climate change and soil erosion
- Pedo-gemomorphology education and scientific dissemination
